SUMMARY OF INVENTION

Technical Problem

In recent years, a need to further change the arrangement of vehicle seats is increasing as autonomous cars spread.

However, since the vehicle disclosed in PATENT LITERATURE 1 has a configuration in which the vehicle seats are moved in the interior space of the vehicle body, a need of an occupant who wants to change the arrangement of the vehicle seats even in an exterior space of the vehicle body could not be sufficiently met.

The present invention has been made in consideration of the above-mentioned problem, and an object of the present invention is to provide a vehicle in which a sense of release can be given to an occupant as a passenger compartment can expand more than that in the related art and vehicle seats can be freely arranged.

Solution to Problem

In order to achieve the object, according to an aspect of the present invention, there is provided a vehicle that includes a vehicle body and vehicle seats arranged in an interior space of the vehicle body. The vehicle body includes a vehicle body floor on which the vehicle seats are arranged and a vehicle body-outer wall part that is disposed to surround the vehicle seats; the vehicle seat includes a seat body on which an occupant is seated, and a moving device that allows the seat body to be mounted and to move with respect to the vehicle body floor; at least a part of the vehicle body-outer wall part is provided to be switchable between a closed position at which an interior space of the vehicle body is closed and an open position at which the interior space of the vehicle body is opened; the moving device includes an operation part to be operated by the occupant and moves the seat body between a reference position and an upper position moved upward from the reference position as the operation part is operated; and at least a part of the seat body is disposed above at least the part of the vehicle body-outer wall part having been in the closed position when at least the part of the vehicle body-outer wall part is in the open position and the seat body is in the upper position.

According to the above-mentioned configuration, it is possible to realize a vehicle in which a sense of release can be given to an occupant as a passenger compartment can expand and vehicle seats can be freely arranged.

Specifically, since at least a part of the vehicle body-outer wall part can be switched from the reference position to the open position, the seat body is moved upward as being operated by the occupant. Then, at least a part of the seat body is moved to an exterior space of the vehicle body. Accordingly, since the passenger compartment expands and the seat body is moved to the exterior space of the vehicle body, a sense of release can be given to the occupant. Particularly, since an occupant can operate by oneself to move the vehicle seats to a desired position, it is possible to arrange the seat bodies in various ways.

In this case, the seat body may include a seat back and a headrest provided above the seat back. When at least the part of the vehicle body-outer wall part is in the open position and the seat body is in the upper position, an upper end portion of the headrest may be disposed above at least the part of the vehicle body-outer wall part having been in the closed position.

According to the above-mentioned configuration, since the height position of the headrest (the position of the sight line of the occupant) is moved to the exterior space of the vehicle body, the position of the sight line of the occupant becomes higher than the interior space of the vehicle body. As a result, a sense of release of the occupant can be further improved.

In this case, the vehicle body-outer wall part may include a vehicle body-upper wall portion that is disposed above the vehicle seats, and a sunroof that is mounted on the vehicle body-upper wall portion and is disposed at a position corresponding to the seat bodies. The sunroof may be provided to be switchable between the closed position and the open position. When the sunroof is in the open position and the seat body is in the upper position, at least the part of the seat body may be disposed above the sunroof having been in the closed position.

According to the above-mentioned configuration, as the sunroof disposed above the seat bodies is switched from the reference position to the open position, the passenger compartment expands and the seat body is moved up to the exterior space of the vehicle body. As a result, a sense of release can be given to the occupant.

In this case, one end portion and the other end portion of the sunroof in a front to rear direction may be arranged at the same height position as the vehicle body-upper wall portion when the sunroof is in the closed position, and the one end portion and the other end portion may be arranged at a position higher than the vehicle body-upper wall portion when the sunroof is in the open position.

According to the above-mentioned configuration, as the entire sunroof is switched from the reference position to the open position, the passenger compartment can further expand.

In this case, one end portion and the other end portion of the sunroof in a front to rear direction may be arranged at the same height position as the vehicle body-upper wall portion when the sunroof is in the closed position, and the one end portion may be disposed at the same height position as the vehicle body-upper wall portion and the other end portion may be disposed at a position higher than the vehicle body-upper wall portion when the sunroof is in the open position.

According to the above-mentioned configuration, as one side of the sunroof is switched from the reference position to the open position, the passenger compartment can expand with a simple configuration.

In this case, the vehicle may include a first seat body and a second seat body disposed behind the first seat body, on the vehicle body floor, the moving device may move the second seat body between the reference position and the upper position as the operation part is operated, and an upper end portion of the second seat body may be disposed above the sunroof having been in the closed position and above an upper end portion of the first seat body when the sunroof is in the open position and the second seat body is in the upper position.

According to the above-mentioned configuration, since the position of the sight line of an occupant seated on the rear seat body becomes higher the position of the front seat body, the sight line of the rear occupant is not blocked and a sense of release can be given to the rear occupant.

In this case, the vehicle body-outer wall part may include a first sunroof mounted on the vehicle body-upper wall portion and a second sunroof disposed behind the first sunroof, and at least one of the first sunroof and the second sunroof may be provided to be switchable between the closed position and the open position.

According to the above-mentioned configuration, since the sunroof is divided and switched from the reference position to the open position, the passenger compartment can expand in various ways.

In this case, the vehicle may include a first seat body disposed below the vehicle body-upper wall portion and a second seat body disposed below the sunroof and behind the first seat body, on the vehicle body floor, the moving device may move the second seat body between the reference position and the upper position as the operation part is operated, and at least a part of the second seat body may be disposed above the sunroof having been in the closed position when the sunroof is in the open position and the second seat body is in the upper position.

According to the above-mentioned configuration, as the sunroof disposed above the rear seat body is switched from the reference position to the open position, the passenger compartment expands and the rear seat body is moved up to the exterior space of the vehicle body. As a result, a sense of release can be given to the rear occupant even when the front occupant drives the vehicle.

In this case, the vehicle may include a first seat body and a second seat body disposed behind the first seat body, on the vehicle body floor, the moving devices may move the first seat body and the second seat body between the reference position and the upper position as the operation parts are operated, and the first seat body may be disposed at a height position different from a height position of the second seat body when at least the part of the vehicle body-outer wall part is in the open position and the first seat body and the second seat body are in the upper position.

According to the above-mentioned configuration, since each of the plurality of seat bodies can be moved, it is possible to freely arrange the vehicle seats.

In this case, the vehicle seat may include a rotating device that allows the seat body to be mounted and to rotate with respect to the vehicle body floor about an axis parallel to an up to down direction, and the rotating device may rotate the seat body by being operated by the occupant when at least the part of the vehicle body-outer wall part is in the open position and the seat body is in the upper position.

According to the above-mentioned configuration, since the seat body can be rotated, it is possible to freely arrange the vehicle seats.

Meanwhile, the present invention is not limited to a configuration in which the height of the seat body 20 is adjusted by the control of the drive motor, and may have a configuration in which, for example, the height of the seat body 20 is adjusted by a manual operation of an operation lever.

As shown in FIGS. 1 and 2, the lifting devices 30 move the seat bodies 20 between a reference position P3 and an upper position P4 moved upward from the reference position P3 as the lifting operation parts 32 are operated by occupants.

When the sunroof 16 is in the open position P2 and the seat bodies 20 are in the upper position P4 as shown in FIG. 2, upper end portions (the upper end portions of the headrests 23) of the seat bodies 20 are disposed above the sunroof 16 having been in the closed position P1.

An occupant switches the sunroof 16 of the vehicle body-outer wall part 10 to the open position P2 and operates the lifting operation part 32 to move the seat body 20 up. Accordingly, the occupant can move the headrest 23 of the seat body 20 to the exterior space of the vehicle body 1 to make the position of a sight line higher than the vehicle body-outer wall part 10. Therefore, a sense of release can be given to the occupant.

Since the passenger compartment can be expanded and the seat body 20 can be moved to the exterior space of the vehicle body 1 as described above, the moving distance of the seat body 20 in a height direction can be significantly increased. Particularly, since an occupant can operate the lifting operation part 32 by oneself to move the seat body 20 to a desired position, it is possible to arrange the seat bodies 20 in various ways.

The rotating device 40 is a device that allows the seat body 20 to move rotationally with respect to the vehicle body floor 15, and includes a rotating operation member 41 to be operated by an occupant. The rotating device 40 is mounted on a lower portion of the lifting device 30, and allows the seat body 20 and the lifting device 30 to be rotatably moved with respect to the vehicle body floor 15.

A drive motor provided in the rotating device 40 can be controlled to rotate the seat body 20 with respect to the vehicle body floor 15. Meanwhile, as with the lifting operation part 32, the rotating operation member 41 may also be provided on the vehicle body-side wall portion 14 or may be provided separately from the vehicle body 1 or the vehicle seat 2 like a remote controller.

An occupant can operate the drive motor by a button pressing operation for the rotating operation member 41 to adjust the orientation of the seat body 20 to a desired position.

Meanwhile, the present invention is not limited to a configuration in which the orientation of the seat body 20 is adjusted by the control of the drive motor, and may have a configuration in which, for example, the orientation of the seat body 20 is adjusted by a manual operation of a rotating operation lever.

When the seat body 20 is in the reference position P3 or the upper position P4, the rotating device 40 is operated by an occupant to rotate the seat body 20.

In addition, when the sunroof 16 is in the open position P2 and the seat body 20 is in the upper position P4, the rotating device 40 is operated by an occupant to rotate the seat body 20.

Since the seat body 20 can be rotated even in a state where the seat body 20 is moved up as described above, an occupant can operate the rotating operation member 41 by oneself to rotate the seat body 20 to a desired orientation. For this reason, the seat bodies 20 can be arranged in more various ways.

The rail device 50 is disposed between the seat body 20 and the vehicle body floor 15 in the up to down direction, and mainly includes right and left lower rails 51 that are fixed to the vehicle body floor 15 and extend in the front to rear direction of the seat and right and left upper rails 52 that are supported to be slidable along the lower rails 51.

An occupant can adjust the seat body 20 to a desired position in the front to rear direction using a rail operation lever.

Meanwhile, the present invention is not limited to a configuration in which the position of the seat body 20 in the front to rear direction is adjusted by a manual operation of the rail operation lever, and may have a configuration in which, for example, the position of the seat body 20 in the front to rear direction is adjusted by the control of the drive motor.

The reclining device 60 is a device that connects the seat back 21 to the seat cushion 22 to allow the seat back 21 to move rotationally and can lock the seat back 21.

The reclining device 60 has a configuration in which an occupant tilts the seat back 21 rearward while the state of the seat back 21 is an unlocked state, and the state of the seat back 21 returns to a locked state when a reclining operation lever is released at a point of time when a rearward tilt angle reaches a desired angle.

An occupant can tilt the seat back 21 rearward using the reclining operation lever to adjust the rearward tilt angle to a desired angle.

Meanwhile, the present invention is not limited to a configuration in which the tilt angle of the seat back 21 is adjusted by a manual operation of the reclining operation lever, and may have a configuration in which, for example, the tilt angle of the seat back 21 is adjusted by the control of the drive motor.

When the seat body 20 is moved to the exterior space of the vehicle body 1 by the lifting device 30 and the rail device 50 as described above, the orientation and the tilt angle of the seat can be changed by the rotating device 40 and the reclining device 60.

The seat back 621 is transformed into a desk shape when being folded down by a reclining device 660 such that the back side of the seat back 621 faces upward.

Meanwhile, as shown in FIG. 18, the seat body 620 may include a footrest 624 that is mounted on a seat cushion 622 to be rotationally movable.

When the seat bodies 620 are moved to an exterior space by the lifting devices 630 and the rail devices 650 as described above, it is possible to arrange the seat bodies 620 in a desired form, such as a footrest shape or a desk shape, by changing the orientations and the tilt angles of the seats with rotating devices 640 and the reclining devices 660. Further, since the positions of the seat bodies 620 can be finely adjusted in the front to rear direction with the first sub-rails 650d and the second sub-rails 650e, it is possible to arrange the seat bodies 620 in a more desired form.

Furthermore, when the right front seat body 620A and the left front seat body 620C are moved to the exterior space as shown in FIG. 18, it is possible to arrange the plurality of seat bodies 620 in a still more desired form by changing the orientations of the seats with the rotating devices 640 to allow the seats to face each other and changing the orientations and the tilt angles of the seats with the reclining devices 660.

Eighth Embodiment

Next, a vehicle V8 according to an eighth embodiment will be described with reference to FIG. 19.

Meanwhile, the repeated description of the same contents as the vehicles V1 to V7 described above will be omitted.

The vehicle V8 according to the eighth embodiment is mainly different from the vehicles V1 to V7 in terms of the configuration of sunroofs 716 and seat bodies 720.

As shown in FIG. 19, the sunroofs 716 are mounted by shafts, which extend in the front to rear direction, to be rotationally movable with respect to an upper surface of a vehicle body-outer wall part 710. Specifically, fixed end portions 716b that are end portions of the sunroofs 716 in the right to left direction are mounted on the vehicle body-outer wall part 710 to be rotationally movable.

The sunroofs 716 are provided to be switchable between a closed position P1 at which an interior space of a vehicle body 701 is closed and an open position P2 at which the interior space of the vehicle body 701 is opened as movable end portions 716a are moved upward.

As shown in FIG. 10, lifting devices 730 move a right front seat body 720A and a left front seat body 720C between a reference position P3 and an upper position P4 moved upward from the reference position P3 as a lifting operation part 732 is operated by an occupant.

A front rail device 750 of the vehicle body 701 includes two lower rails 750a that extend in the right to left direction, two first upper rails 750b that are provided on the right front seat body 720A and are supported to be slidable along the lower rails 750a, and two second upper rails 750c that are provided on the left front seat body 720C and are supported to be slidable along the lower rails 750a.

Further, the seat body 720 includes massage devices 770 in a seat back 721 and a seat cushion 722.

The massage device 770 is to operate to correct the posture of an occupant seated in the seat. The massage device 770 is, for example, an air bag and bulges to correct the posture of a seated occupant as air is injected into the air bag.

Meanwhile, a mechanism for pressing the seated occupant is not limited to an object that bulges as with an air bag or a bag body, and may be a mechanism for pushing members having a fixed shape, such as roller-shaped bodies, ball-shaped bodies, or block-shaped bodies, against a seated occupant to press the seated occupant.

When the seat bodies 720 are moved to an exterior space of the vehicle body 701 by the lifting devices 730 and the rail devices 750 as described above, the orientations and the tilt angles of the seats can be changed by rotating devices 740 and reclining devices 760. Then, the right front seat body 720A is disposed at a position at which the massage devices 770 press the shoulder and waist of a seated occupant, and the left front seat body 720C is disposed at a position at which the massage device 770 presses legs of the seated occupant. Accordingly, since the occupant can get a massage in the exterior space of the vehicle body 701, the occupant can further feel a sense of release.

In addition, the left front seat body 720C is rotated by the rotating device 740 such that the back side of the seat back 721 faces the right front seat body 720A. Accordingly, the occupant seated in the right front seat body 720A can use the seat back 721 and a headrest 723 of the left front seat body 720C as a footrest.

Ninth Embodiment

Next, a vehicle V9 according to a ninth embodiment will be described with reference to FIGS. 20 to 24.

Meanwhile, the repeated description of the same contents as the vehicles V1 to V8 described above will be omitted.

A tailgate 819 is mounted to be openable and closable with respect to a vehicle body-outer wall part 810, and includes a rear glass part 819a, a gate part 819b that is mounted to be rotationally movable with respect to the rear glass part 819a, and an awning part 819c that is slidably mounted on the gate part 819b.

The tailgate 819 is provided to be switchable between a closed position P5 at which an interior space of a vehicle body 801 is closed and an open position P6 at which the interior space of the vehicle body 801 is opened.

The gate part 819b is in a horizontal position when the rear glass part 819a rotationally moves rearward, and can be used as, for example, a rain cover and a sunshade for a left rear seat body 820D.

The awning part 819c slides rearward to extend from the gate part 819b when the gate part 819b is in the horizontal position. The awning part 819c can be used as a rain cover and a sunshade when, for example, the left rear seat body 820D has been moved to a rear position P8.

The vehicle V9 includes a plurality of seat bodies 820. Specifically, the vehicle V9 includes a right front seat body 820A, a right rear seat body 820B disposed behind the right front seat body 820A, a left front seat body 820C disposed on the left side of the right front seat body 820A, and a left rear seat body 820D disposed behind the left front seat body 820C, on a vehicle body floor 815.

As shown in FIG. 20, lifting devices 830 move the seat bodies 820 between a reference position P3 and an upper position P4 moved upward from the reference position P3 as being operated by occupants.

For example, when a sunroof 816 is in an open position P2 and each seat body 820 is in the upper position P4 as shown in FIG. 20, an upper end portion (an upper end portion of a headrest 823) of the seat body 820 is disposed above the sunroof 816 having been in a closed position P1.

A rail device 850 includes two lower rails 850a that extend in the front to rear direction, two upper rails 850b that are supported to be slidable along the lower rails 850a, and two sub-rails 850c that are slidably supported by the upper rails 850b.

Sub-rails 850c of a left rail device 850 of the vehicle body 801 allow the right rear seat body 820B and the left rear seat body 820D to move in the front to rear direction. Likewise, the front rail device 850 may also be adapted to include sub-rails 850c.

Meanwhile, as shown in FIG. 21, a battery 803 for driving a vehicle is disposed on the inner side than the right lower rail 850a of the rail device 850 for the right front seat body 820A and the right rear seat body 820B, which are provided on the right side in the vehicle body 801, in the right to left direction. Further, the battery 803 is disposed on the inner side than the left lower rail 850a of the rail device 850 for the left front seat body 820C and the left rear seat body 820D, which are provided on the left side in the vehicle body 801, in the right to left direction.

As shown in FIG. 20, the rail device 850 moves the seat body 820 between a reference position P7 and a rear position P8 moved to the rear side (outside) of the reference position P7 as a rail operation lever is operated by an occupant.

For example, when the tailgate 819 is in the open position P6 and the left rear seat body 820D is in the rear position P8 as shown in FIG. 20, the left rear seat body 820D is disposed behind the tailgate 819 having been in the closed position P5.

Since a passenger compartment can be expanded and the seat body 820 can be moved to an exterior space of the vehicle body 801 by the lifting device 830 and the rail device 850 as described above, the moving distance of the seat body 820 in the front to rear direction can be significantly increased. Particularly, since an occupant can operate by oneself to move the seat body 820 to a desired position, it is possible to arrange the seat bodies 820 in various ways.

Further, when the seat body 820 is moved to the exterior space, it is possible to change the orientation and the tilt angle of the seat by the rotating device 840 and the reclining device 860 and to arrange the seat body 620 at a desired position.

Modification examples of the vehicle V8 will be described below.

Specifically, lower rails 850a of a rail device 850 are formed in a shape in which portions extending in the front to rear direction and portions extending in the right to left direction cross each other. Accordingly, upper rails 850b mounted on the lower rails 850a are slidable with respect to the lower rails 850a not only in the front to rear direction but also in the right to left direction, so that the seat bodies 820 can be arranged at various positions.

Meanwhile, portions of the lower rails 850a extending in the front to rear direction are not provided on a driver seat side where a steering wheel 870 is provided. That is, the left front seat body 820C serving as a passenger seat is disposed in front of the right front seat body 820A serving as a driver seat when being moved forward along the rail device 850.

Further, the vehicle body 801 includes a partition 871 that divides the passenger compartment into a driver seat side (right area) and a passenger seat side (left area). The partition 871 is to partition off private spaces for occupants, is mounted on the vehicle body-outer wall part 810 or the vehicle body floor 815, and is provided to be switchable between a use position and a storage position. The partition 871 is, for example, a bellows-shaped curtain, extends up to a position at which the partition 871 divides the driver seat from the passenger seat at the use position (a solid line in FIG. 22), and is folded and stored at a position at which the partition 871 does not divide the driver seat from the passenger seat at the storage position (a dotted line in FIG. 22). Meanwhile, the partition 871 may be a sliding panel.

The vehicle V13 includes a battery 1203 and a plurality of seat bodies 1220. Specifically, the vehicle V13 includes a front seat body 1220A, a middle seat body 1220B disposed behind the front seat body 1220A, and a rear seat body 1220C disposed behind the middle seat body 1220B, on a vehicle body floor 1215.

The front seat body 1220A includes an elastic spring (not shown) that generates a biasing force toward the front. The front seat body 1220A is moved with respect to the vehicle body floor 1215 in a direction in which the front seat body 1220A approaches the vehicle body-front wall portion 1213 (forward) by the biasing force of the elastic spring. Accordingly, an occupant is seated in the front seat body 1220A, presses the vehicle body-front wall portion 1213 with feet against the biasing force, and moves the front seat body 1220A with respect to the vehicle body floor 1215 in a direction in which the front seat body 1220A is away from the vehicle body-front wall portion 1213 (rearward), so that the occupant can perform foot muscle exercises.

The middle seat body 1220B includes an elastic spring (not shown) that generates a biasing force toward the rear. A seat back 1221 is rotationally moved with respect to the seat cushion 1222 in a direction in which the seat back 1221 approaches the rear seat body 1220C (rearward) by the biasing force of the elastic spring. Accordingly, an occupant is seated in the rear seat body 1220C, presses the seat back 1221 of the middle seat body 1220B with feet against the biasing force, and moves the middle seat body 1220B in a direction in which the middle seat body 1220B is away from the rear seat body 1220C (forward), so that the occupant can perform foot muscle exercises.

An exercise device 1270 (roof handle 1271) is mounted on a lower surface of a front portion of the upper wall-rear portion 1212b. The roof handle 1271 is a member that is gripped by an occupant when the occupant seated in the middle seat body 1220B performs pull-up exercises to pull up the upper half of the body.

When the sunroof (not shown) is in an open position and the rear seat body 1220C is in an upper position, an upper end portion of the rear seat body 1220C is disposed above the sunroof having been in a closed position (that is, the upper wall-rear portion 1212b) as shown in FIG. 29.

When the front seat body 1220A, the middle seat body 1220B, and the rear seat body 1220C are in upper positions, respectively, the height of a sight line for the front seat body 1220A overlaps the front portion 1218a. The height of a sight line for the middle seat body 1220B overlaps the rear portion 1218b.

That is, the front portion 1218a and the rear portion 1218b are provided at positions at which a field of view in front of occupants seated on the seat bodies 1220 is secured even when the seat bodies 1220 are moved in the up to down direction.

Since the seat bodies 1220 can be moved by lifting devices 1230 and a rail device 1250 as described above, it is possible to arrange the seat bodies 1220 in various ways.

Further, it is possible to change the orientations and the tilt angles of the seats by rotating devices 1240 and reclining devices 1260 and to arrange the seat bodies 1220 at desired positions.

Furthermore, an occupant can move the rear seat body 1220C to an exterior space of the vehicle body 1201 to make the position of a sight line higher than the vehicle body-upper wall portion 1212. Therefore, a sense of release can be given to the occupant.

Since the vehicle V13 according to this embodiment can be used as a gym vehicle in which an occupant can exercise, it is possible to arrange the seat bodies 1220 in a way suitable for exercises while improving a sense of release.

Fourteenth Embodiment

Next, a vehicle V14 according to a fourteenth embodiment will be described with reference to FIG. 30.

Meanwhile, the repeated description of the same contents as the vehicles V1 to V13 described above will be omitted.

The vehicle V14 according to the fourteenth embodiment is mainly different from the vehicles V1 to V13 in terms of the configuration of a vehicle seat 1301. The vehicle seat 1301 is applied to, for example, a passenger seat for an autonomous car. Meanwhile, the vehicle seat 1301 may be applied to seats other than the passenger seat.

The vehicle seat 1301 includes a seat body that includes a seat back 1302 and a seat cushion 1303, a rotating device 1304 that allows the seat body to be mounted and to rotate with respect to a vehicle body floor about an axis parallel to the up to down direction, and a cushion-rotational movement device 1305 that connects the seat cushion 1303 to the seat back 1302 to allow the seat cushion 1303 to move rotationally.

When an occupant seated in a driver seat is to move to a rear seat, the occupant causes the seat cushion 1303 to rotationally move (tip up) with respect to the seat back 1302 by the cushion-rotational movement device 1305 to make a tip-up state where the seat back 1302 and the seat cushion 1303 are in contact with each other. Then, in this tip-up state, the occupant rotates the seat body with respect to the vehicle body floor in a horizontal direction by an angle of 90 degrees with the rotating device 1304 to make a walk-through state where the occupant can move to the rear seat.

In this case, the occupant may rotate the seat body in the tip-up state or may make the tip-up state after rotating the seat body. Alternatively, the occupant may tip up the seat cushion and rotate the seat body at the same time.

When the disposition of the seat body is changed by the rotating device 1304 and the cushion-rotational movement device 1305 as described above, it is possible to meet a need in which an occupant wants to relax in the rear seat during autonomous driving. Particularly, an occupant seated in the driver seat can easily move to the rear seat even in the case of a compact car having a small interior space of a vehicle body.

A publicly known technique can be used for drive mechanisms of the rotating device 1304 and the cushion-rotational movement device 1305, and the rotating device 1304 and the cushion-rotational movement device 1305 may be manually driven or driven by motors.

The rotating device 1304 may be embedded below the vehicle body floor. In this case, a pillar member connecting the rotating device 1304 and the seat cushion 1303 may be provided.

A hook for hanging baggage, a wireless charger for charging an electronic equipment, a USB port for communication with the vehicle V14, or the like may be provided on back surfaces or side surfaces of the seat back 1302 and the seat cushion 1303 of the vehicle seat 1301.

A folding table and the like may be further provided on the back surface of the seat cushion 1303.

Further, a passenger seat may be adapted to be capable of being manually driven in a walk-through state. In this case, the rotation angle of the seat body may be adapted to be fixed at an angle (for example, 45 degrees) other than 90 degrees. Accordingly, a field of view on the side can be secured even in the walk-through state.

Furthermore, a seat belt reminder detecting that an occupant is seated in a passenger seat may be provided. At this time, in a case where the seat belt reminder detects that an occupant is seated, it is preferable to perform control to prevent the rotation of the seat body.

In addition, even in a case where the seat belt reminder detects that a child seat, baggage, or the like is placed on the seat body, control to prohibit the rotation of the seat body may be performed.

Fifteenth Embodiment

Next, a vehicle V15 according to a fifteenth embodiment will be described with reference to FIG. 31.

Meanwhile, the repeated description of the same contents as the vehicles V1 to V14 described above will be omitted.

The vehicle V15 according to the fifteenth embodiment is mainly different from the vehicles V1 to V14 in terms of the configuration of a vehicle seat 1401 and a door panel 1450.

The vehicle seat 1401 includes a seat back 1402, a seat cushion 1403, a headrest 1404, an armrest 1405 that is mounted to be rotationally movable with respect to the seat back 1402, an operation device 1410 that is mounted on a seating surface for an occupant, and a control device 1460.

The armrest 1405 is mounted to be rotationally movable between a storage position at which the armrest 1405 is stored on the side surface of the seat back 1402 and a support position at which the armrest 1405 can support an occupant's arm.

As shown in FIG. 31, a blower device 1420, heating devices 1430, and airbag modules 1440 are arranged on the seat back 1402.

The blower device 1420 is adapted to blow air out of a first blow-out port 1421 toward a seated occupant through a duct from a blower body. The first blow-out port 1421 is provided on the surface of a middle support portion 1402a of the seat back 1402 facing a seated occupant.

The heating devices 1430 are heaters for heating a seated occupant and are provided in side support portions 1402b of the seat back 1402.

The airbag modules 1440 are provided in the side support portions 1402b of the seat back 1402 below the heating devices 1430.

As shown in FIG. 31, second blow-out ports 1422 of the blower device 1420 are arranged on the seat cushion 1403.

The second blow-out ports 1422 are provided on front surfaces of a middle support portion 1403a and side support portions 1403b of the seat cushion 1403.

As shown in FIG. 31, a third blow-out port 1423 of the blower device 1420 is disposed on the armrest 1405.

The third blow-out port 1423 is provided on the surface of the armrest 1405 facing a seated occupant at a tip portion of the armrest 1405 in a longitudinal direction. Meanwhile, an armrest ventilation channel 1406 that allows air from the blower body to pass therethrough is formed in the armrest 1405.

Since the armrest 1405 is mounted to be rotationally movable with respect to the seat back 1402, the position of the third blow-out port 1423 can be adjusted. Accordingly, since the position of the third blow-out port 1423 can be adjusted, an occupant can apply air having passed through the armrest ventilation channel 1406 to a desired position.

Meanwhile, the tip portion of the armrest 1405 in the longitudinal direction may be adapted to be rotatable about an axis parallel to the longitudinal direction of the armrest 1405. Accordingly, since an angle of the third blow-out port 1423 provided at the tip portion of the armrest 1405 in the longitudinal direction can be adjusted, the third blow-out port 1423 can be directed to an occupant and air can be efficiently sent to the occupant.

Further, the armrest 1405 is provided at a position at which the third blow-out port 1423 does not overlap the seat back 1402 in the right to left direction when being in the storage position. That is, since the armrest 1405 is disposed at a position at which the third blow-out port 1423 is not closed by the seat back 1402 when being in the storage position, air can be efficiently sent to the neck or chest of an occupant.

Meanwhile, the present invention is not limited to a configuration in which the armrest 1405 is provided on only one side of the seat back 1402, and it is preferable that armrests 1405 are provided on both right and left sides of the seat back 1402 in the seat width direction. Accordingly, air can be more efficiently sent to an occupant.

The operation device 1410 includes a mat part 1411 that is formed of a cushion member, a mat holding part 1412 that allows the mat part 1411 to be detachably mounted on the seat body, and sensor parts 1413 that are provided in the mat part 1411.

As shown in FIG. 31, the mat part 1411 includes a first mat portion 1411a that is disposed at a position corresponding to the middle support portion 1402a of the seat back 1402, second mat portions 1411b that are arranged at positions corresponding to the side support portions 1402b of the seat back 1402, a third mat portion 1411c that is disposed at a position corresponding to an upper surface of the middle support portion 1403a of the seat cushion 1403, fourth mat portions 1411d that are arranged at positions corresponding to the side support portions 1403b of the seat cushion 1403, and a fifth mat portion 1411e that is disposed at a position corresponding to a front surface of the middle support portion 1403a of the seat cushion 1403.

The thickness of the cushion member at a mat bending portion 1411f that is a connection portion of each of the mat portions (1411a to 1411e) is smaller than the thickness of the cushion member at each of the mat portions.

Meanwhile, since the mat bending portions 1411f are arranged at connection portions of the seat body (for example, connection portions of the middle support portion 1402a and the side support portions 1402b), the positions of the mat bending portions 1411f in the seat width direction are regulated. For this reason, the shift of the position of the operation device 1410 from the seat body can be suppressed.

As shown in FIG. 31, the mat holding part 1412 has a string shape and is mounted on an upper portion of the first mat portion 1411a. The mat holding part 1412 is hooked to headrest pillars of the headrest 1404, so that the mat part 1411 is detachably mounted on the seat body.

In this case, the mat part 1411 is disposed at a position that does not overlap the first blow-out port 1421 and the second blow-out ports 1422 of the blower device 1420, the heating devices 1430, and the airbag modules 1440 in the front to rear direction. Accordingly, the influence of the mat part 1411 on the blower device 1420, the heating devices 1430, and the airbag modules 1440 can be suppressed.

As shown in FIG. 31, the sensor part 1413 is a sheet-shaped pressure sensor that detects a seating pressure applied to the seating surface of the seat body when an occupant is seated in the seat, and is mounted inside the mat part 1411.

Here, “seating pressure” s a value that is periodically changed depending on the physiological activity, specifically, respiration of the seated occupant in a state where the occupant is seated on the seat body, and is an object value that is detected by the pressure sensor.

Meanwhile, the sensor part 1413 may be a seating sensor that is turned on or off depending on the seating pressure of the seated occupant. Preferably, the sensor part 1413 may be a push switch type seating sensor. The sensor part 1413 is not limited to the seating sensor, and may be a heart rate sensor, a respiration sensor, a blood pressure sensor, a pulse wave sensor, or the like.

As shown in FIG. 31, fourth blow-out ports 1424 of the blower device 1420 are arranged on the door panel 1450.

The fourth blow-out ports 1424 are provided on the surface of the door panel 1450 facing a seated occupant. A plurality of fourth blow-out ports 1424 are provided in the up to down direction and are arranged at positions corresponding to the neck, the waist, the femoral region, and the feet of an occupant, respectively.

Meanwhile, a door panel ventilation channel 1451 that allows air from the blower body to pass therethrough is formed in the door panel 1450.

The vehicle seat 1401 can be applied to the following seats.

<<Health Seat>>

A health seat is a seat that allows an occupant to perform core-strengthening exercises while the occupant is seated. In the related art, an EXA-RIDE seat in which a seating surface of a vehicle seat moves has been proposed as a health seat (for example, JP 2018-086996).

However, since the EXA-RIDE seat in which a seating surface moves as in the related art has large movement of the seating surface, there is a concern that a sense of incompatibility is given to an occupant. For this reason, a seat in which a sense of incompatibility to be given to an occupant is further suppressed has been required.

The present invention is to provide a health seat in which a sense of incompatibility to be given to an occupant is further suppressed.

The vehicle seat 1401 as a health seat further includes a vibration device in addition to the above-mentioned configuration.

The vibration device includes a vibration unit that is provided in a seat body at a position corresponding to a seating surface for an occupant (seated occupant) and applies vibration to the seated occupant, and a moving unit that moves the vibration unit to a seated occupant side.

The vibration unit is to provide a stimulus to the back and hips of the seated occupant, and is provided on a seated occupant side in the seat back 1402 and the seat cushion 1403.

The moving unit is, for example, an air cell and is provided on the back side and the lower side (a side away from the seated occupant) of the vibration unit in the seat back 1402 and the seat cushion 1403. The moving unit moves the vibration unit to the seated occupant side in response to a seated occupant's operation.

Specifically, the moving unit moves the vibration unit toward the seated occupant side from the back side in the seat back 1402 by the driving of a motor to press the vibration unit against the back portion and the waist of the seated occupant.

Further, the moving unit moves the vibration unit toward the seated occupant side from the lower side in the seat cushion 1403 by the driving of the motor to press the vibration unit against the hips or the femoral region of the seated occupant.

As described above, the vibration unit is moved to the seating surface of the seat body by the moving unit only when vibration is to be applied to the seated occupant. Accordingly, a sense of incompatibility to be given to the seated t can be suppressed as compared to a configuration in which the vibration unit is always disposed on the seating surface of the seat body.

Meanwhile, the vibration device may be provided with a pressure sensor detecting that the vibration unit is moved to the seating surface. When the pressure sensor detects that the vibration unit is moved to the seating surface, the vibration device limits (stops) the movement of the vibration unit toward the seated occupant side that is performed by the moving unit. Accordingly, the excessive movement of the vibration unit to the seated occupant side can be suppressed.

An example in which the present invention is applied to the vibration device has been described in this embodiment, but the present invention may be applied to a notification device (a light emitting unit or a voice generation unit) in addition to the vibration device. In this case, the light emitting unit or the voice generation unit is moved to the seating surface of the seat body by the moving unit only when a seated occupant is to be notified with light or voice. For this reason, a sense of incompatibility to be given to the seated occupant can be suppressed as compared to a configuration in which the light emitting unit or the voice generation unit is always disposed on the seating surface of the seat body.

Moreover, the present invention may be applied to a detection device (a detection unit to be moved to the seating surface) or a temperature adjustment device (a heater unit to be moved to the seating surface) in addition to the notification device.

<<Desk Seat>>

A desk seat is a seat that can be used as a desk for work or study. In the related art, a seat in which a heater panel provided on the back of a front seat of vehicle seats can be used as a table has been proposed as a desk seat (for example, WO 2018/086996).

However, since a table surface of a desk seat as in the related art is also shaken in a case where a vehicle is shaken, there is a concern that work or study may be disrupted. For this reason, a seat that can notify an occupant in a case where shaking is large has been required.

The present invention is to provide a desk seat that can notify an occupant in a case where shaking is large.

The vehicle seat 1401 as a desk seat further includes a table, a vibration detection device, and a notification device that are provided on the back of a front seat in addition to the above-mentioned configuration.

The vibration detection device includes a shaking detection unit that detects the shaking of a vehicle, and a transmission unit that shaking transmits information detected by the shaking detection unit to the notification device.

The shaking detection unit is to detect vibration that is generated when a vehicle passes through a connection portion or a stepped portion of a road, vibration that is generated when a vehicle is overtaken by a large vehicle, such as a large truck, and the like.

In a case where vibration equal to or higher than a predetermined value is detected by the shaking detection unit, the transmission unit transmits shaking information, which corresponds to the level of the vibration, to the notification device.

The notification device includes a light emitting unit and a voice generation unit that inform an occupant depending on information transmitted from the transmission unit. For example, the notification device turns on the light emitting unit in yellow in a case where the level of the vibration is slightly high, and turns on the light emitting unit in red in a case where the level of the vibration is high.

Meanwhile, in a case where the level of the vibration is very high, the notification device may turn off all illumination for a desk so that an occupant cannot continue work or study.

Since the notification device notifies an occupant of the shaking information detected by the vibration detection device as described above, work or study can be limited (or prohibited).

Meanwhile, the vibration detection device may be adapted not to be provided with the shaking detection unit and to inform an occupant of information on the uneven state of a road surface stored in an in-vehicle navigation device or shaking information (predictive value) calculated on the basis of information on surrounding vehicles acquired by an imaging device. In addition, the vibration detection device may correct the calculated predictive value with a vehicle speed and display the corrected predictive value. In this case, the vibration detection device may display a time required until a state where study can be performed is made in addition to displaying the predictive value.

<<Active Seat>>

An active seat is, for example, a seat that can be used as a controller for a game displayed on a smartphone. An occupant can operate characters in the game displayed on a display by alternately moving up and down the right and left legs on the vehicle seat 1401 or tilting the body.

Since the control device 1460 outputs pressure values acquired from the pressure sensors of the sensor parts 1413 provided in the mat part 1411 to the smartphone as signals for operating a game application of the smartphone, an occupant seated in the vehicle seat 1401 can operate the smartphone by moving one's legs or shoulder on the seat body.

For this reason, an occupant does not need to operate the smartphone with a hand and can operate the smartphone by moving one's body on the seat body.

In addition, it is also possible to vibrate the seating surface of the seat body depending on the development of the game to provide a realistic experience of the game to the occupant. For example, when a balance between the right and left is poor in a game in which a user drives an automobile, the user may feel vibrations that make the user feel bad roads.

Further, the seat body may be rotated by a rotating device or may be moved up and down by a lifting device depending on the progress of the game. In this case, the vehicle seat 1401 may include support parts that prevent an occupant from falling out of the vehicle seat.

The support parts are to support an occupant from the outside in the seat width direction, and are provided on, for example, the seat cushion 1403. The support parts are mounted such that the protruding length of the support part from the seat cushion 1403 can be adjusted.

In addition, it is preferable that the protruding length of the support part can be automatically adjusted depending on the progress of the game by the control device 1460. In this case, information on a situation (the protruding length of the support part, and the like) corresponding to the progress of the game may be displayed on the display.

<<Refreshing Seat>>

A refreshing seat is a seat that provides pleasant wind (cold wind, warm wind), a desired aroma, a desired music, and pleasant vibration to an occupant.

A case where the control device 1460 provides effects of wind, an aroma, a music, and vibration to a seated occupant on the basis of biological information (for example, an electrocardiogram, a blood pressure, a body temperature, respiration, and the like) detected from the sensor parts 1413 provided in the mat part 1411, and the like are assumed.

In addition, the control device 1460 may include artificial intelligence (AI). In this case, a comfort level of an occupant is calculated on the basis of the biological information detected from the sensor parts 1413, and an effect corresponding to the comfort level is provided.

For example, a case where the blower device 1420 is controlled by the control device 1460 including artificial intelligence (AI) to send wind suitable for the characteristics (sensitivity to cold, sensitivity to heat, or the like) of a seated occupant to the occupant, and the like are assumed. In this case, information on the comfort level may be displayed on the display.

<<Stretch Seat>>

A stretch seat is a seat that allows an occupant to perform stretching exercises, such as stretching and twisting one's body. The stretch seat includes a seat rotating device that rotates the seat cushion 1403 with respect to the seat back 1402 about an axis parallel to the seat front to rear direction of the seat as a rotation axis in response to an occupant's operation, and a reclining device that connects the seat back 1402 to the seat cushion 1403 to allow the seat back 1402 to move rotationally in response to an occupant's operation.

An occupant can perform an exercise to twist the lower half of the body by rotating the seat cushion 1403 with respect to the seat back 1402 with the seat rotating device while holding the upper half of the body with the armrest 1405.

Further, an occupant can perform an exercise to bend the body backward and to stretch the body by rotating the seat back 1402 with respect to the seat cushion 1403 with the reclining device such that the seat back 1402 is disposed on the lower side.

In this case, information on the degree of flexibility (the degree of twisting, the degree of stretching, and the like) may be displayed on the display.

<<Sport Gym Seat>>

A sport gym seat is a seat that allows an occupant to train muscles. The vehicle seat 1401 as a sport gym seat includes elastic members on the members (the seat back 1402, the seat cushion 1403, the armrest 1405, and the like), respectively.

An occupant can perform exercises to strength muscles by pressing the elastic member against a biasing force with arms or legs.

In this case, information on training results (the degree of pressing, the number of times of pressing, and the like) may be displayed on the display.

Sixteenth Embodiment

Next, a vehicle V16 according to a sixteenth embodiment will be described with reference to FIGS. 32 and 33.

Meanwhile, the repeated description of the same contents as the vehicles V1 to V15 described above will be omitted. The vehicle V16 according to the sixteenth embodiment is mainly different from the vehicles V1 to V15 in terms of the configuration of a vehicle seat 1501 and a door panel 1530.

As shown in FIG. 32, the vehicle seat 1501 includes a seat back 1502, a seat cushion 1503, headrests 1504, an armrest 1505 that is mounted to be rotationally movable with respect to the seat back 1502, sensor parts 1510, a blower device 1520, and a control device 1540.

The armrest 1505 is mounted to be rotationally movable between a storage position at which the armrest 1505 is stored in the side surface of the seat back 1502 and a support position at which the armrest 1505 can support an occupant's arm.

The blower device 1520 is adapted to blow air out of a seat-side blow-out port 1521 toward a seated occupant through a duct from a blower body. The seat-side blow-out port 1521 is provided on the side surface of the armrest 1505 facing a seated occupant. Meanwhile, an armrest ventilation channel 1506 that allows air from the blower body to pass therethrough is formed in the armrest 1505.

Since the armrest 1505 is mounted to be rotationally movable with respect to the seat back 1502, the position of the seat-side blow-out port 1521 can be adjusted. Accordingly, since the position of the seat-side blow-out port 1521 can be adjusted, an occupant can apply air having passed through the armrest ventilation channel 1506 to a desired position.

As shown in FIG. 33, the door panel 1530 includes a movable door armrest 1531. A door-side blow-out port 1522 of the blower device 1520 is disposed on the surface of a movable arm part 1532 of the door armrest 1531.

Meanwhile, a movable arm ventilation channel 1533 that allows air from the blower body to pass therethrough is formed in the door armrest 1531.

Since the movable arm part 1532 is mounted to be slidable with respect to the door armrest 1531 in the front to rear direction, the position of the door-side blow-out port 1522 can be adjusted. Accordingly, since an occupant can adjust the position of the door-side blow-out port 1522, the occupant can apply air having passed through the movable arm ventilation channel 1533 to a desired position.

The control device 1540 may drive the blower device 1520 according to a seating state of the occupant that is detected by the sensor parts 1510. Accordingly, since the blower device 1520 can be driven only when the occupant is seated, power consumption can be reduced.

Seventeenth Embodiment

Next, a vehicle V17 according to a seventeenth embodiment will be described with reference to FIG. 34.

Meanwhile, the repeated description of the same contents as the vehicles V1 to V16 described above will be omitted.

The vehicle V17 includes vehicle seats 1601, an instrument panel part 1602, first pillar portions 1603, second pillar portions 1604, a ceiling portion 1605, a console box 1606, a sterilization device 1610, and a blower device 1620.

The sterilization device 1610 is to perform sterilization treatment, such as sterilization, disinfection, air cleaning, deodorization, and ventilation for an interior space of the vehicle V17.

For example, ozone having a strong sterilization effect can be used for sterilization treatment for the vehicle V17. The closed interior space of the vehicle V17 is fumigated with ozone by an ozone generation device, so that sterilization treatment is performed.

A first slit blow-out port 1623 and a second slit blow-out port 1624 are fumigation ports of the ozone generation device. The first slit blow-out port 1623 is provided over the first pillar portions 1603 and the ceiling portion 1605. The second slit blow-out port 1624 is provided over the second pillar portions 1604 and the ceiling portion 1605.

Meanwhile, the first slit blow-out port 1623 and the second slit blow-out port 1624 may also be used as blow-out ports of the blower device 1620. In this case, fumigation ports and blow-out ports are alternately arranged at interval of, for example, 50 mm.

The sterilization treatment is started when various sensors detects that no occupant is present in the vehicle V17. In the vehicle V17, doors are locked when the sterilization treatment is started and the opening of the doors is prohibited until the sterilization treatment ends. Accordingly, an occupant is prevented from accidentally getting in the vehicle V17 during the sterilization treatment. In this case, an occupant may be informed that an occupant cannot get in the vehicle during the sterilization treatment.

After fumigation using ozone ends, ventilation for making an air state where an occupant can get in the vehicle V17 is performed by a ventilator. When the sterilization treatment ends, an occupant may be informed that disinfection has been performed.

For the sterilization treatment, ozone does not necessarily need to be used and a disinfectant, such as alcohol, may be sprayed. In this case, the disinfectant is stored in a chemical storage part 1611 and is sprayed into the interior space of the vehicle V17 from instrument panel blow-out ports 1621 of the instrument panel part 1602 by the blower device 1620.

Meanwhile, the disinfectant may be sprayed into the interior space of the vehicle V17 from console box blow-out ports 1622 of the console box 1606. Further, the disinfectant may be sprayed using ventilation channels formed in the seat bodies of the vehicle seats 1601.

After the spray of the disinfectant ends, ventilation for making an air state where an occupant can get in the vehicle V17 is performed by the ventilator.

Eighteenth Embodiment

Next, a vehicle V18 according to an eighteenth embodiment will be described with reference to FIGS. 35 and 36.

Meanwhile, the repeated description of the same contents as the vehicles V1 to V17 described above will be omitted.

As shown in FIGS. 35 and 36, a vehicle seat 1701 includes a seat back 1702, a seat cushion 1703, a headrest 1704, and sterilization devices 1710.

The sterilization devices 1710 are to perform sterilization treatment for an occupant seated in the vehicle seat 1701. The sterilization devices 1710 are, for example, LEDs that can apply ultraviolet light or LEDs that use a specific wavelength in visible light, and are arranged in the seat back 1702, the seat cushion 1703, and the headrest 1704. Meanwhile, the shape of the LED may be a rod shape or a dot shape. Further, a cloth-shaped member that emits ultraviolet light may be disposed under an outer skin.

As shown in FIGS. 35 and 36, the sterilization devices 1710 are arranged at positions corresponding to apocrine glands of an occupant in the seat back 1702, the seat cushion 1703, and the headrest 1704. Groove portions or concave portions are formed on the seat back 1702, the seat cushion 1703, and the headrest 1704, and the sterilization devices 1710 are arranged in the groove portions or the concave portions.

Since the sterilization devices 1710 are arranged in the groove portions or the concave portions, a sense of incompatibility to be given to an occupant can be suppressed as compared to a case where the sterilization devices 1710 are arranged on the seating surface of the seat.

Nineteenth Embodiment

Next, a vehicle V19 according to a nineteenth embodiment will be described with reference to FIGS. 37 to 39.

Meanwhile, the repeated description of the same contents as the vehicles V1 to V18 described above will be omitted.

The vehicle V19 is an autonomous four-wheeled electric vehicle (EV) of which the form is changed, for example, when an occupant drives the vehicle and when an occupant gets in and off the vehicle as shown in FIGS. 37 and 38, and includes a vehicle body 1801 that is long in the front to rear direction and a vehicle seat 1802 that is disposed in an interior space of the vehicle body 1801.

Meanwhile, the vehicle V19 is not limited to a four-wheeled autonomous car, and may be, for example, three-wheeled (two front wheels, one rear wheel) autonomous car.

The vehicle V19 is adapted to be switchable between a traveling mode (FIG. 37) in which the vehicle travels and a getting-in/off mode (FIG. 38) in which an occupant can get in and off. The traveling mode is a state where the vehicle body 1801 lies down, and the getting-in/off mode is a state where the vehicle body 1801 stands up.

Meanwhile, the vehicle V19 may include an informing unit that allows an occupant to check a change in the form of the vehicle body 1801 and a permission operation unit that allows an occupant to perform an operation for permitting a change in the form of the vehicle body 1801, when the traveling mode and the getting-in/off mode are switched. Accordingly, for example, when two or more occupants get in the vehicle, it is possible to suppress the unexpected operation of the vehicle body 1801.

Since the vehicle body 1801 is long in the front to rear direction and a front end portion thereof has a rounded shape, wind resistance of the vehicle body 1801 is reduced in the traveling mode. As a result, fuel efficiency can be improved. Further, since the interior space of a passenger compartment can be made small, air-conditioning performance in the interior space can be improved.

Furthermore, when the vehicle V19 is to be parked, the vehicle V19 may be switched to the getting-in/off mode. Accordingly, a parking space can be reduced in size.

The vehicle body 1801 includes a vehicle body-outer wall part 1810 that partitions off the interior space of the vehicle body 1801 from an exterior space of the vehicle body, a door part 1811 that allows an occupant to get in and off the vehicle, front tires 1812, rear tires 1813, a tire link part 1814 that is mounted on a middle portion of the vehicle body-outer wall part 1810 in a longitudinal direction, a display device 1830 that is mounted on the inside of the door part 1811, and a storage device 1840 that is mounted on the vehicle body-outer wall part 1810 to be rotationally movable.

The vehicle body-outer wall part 1810 includes, at a front end portion (a position corresponding to a lower end portion in the getting-in/off mode), a charging unit 1810a that is used to charge the vehicle V19 and a state detection sensor 1810b that detects the state of the vehicle body 1801. Further, the vehicle body-outer wall part 1810 includes, at a rear end portion (a position corresponding to an upper end portion in the getting-in/off mode), an upper detection sensor 1810c that detects an obstacle present above the vehicle body 1801.

A battery (not shown) of the vehicle V19 can be charged through a wire or wirelessly by the charging unit 1810a.

Furthermore, whether the vehicle body 1801 is in the traveling mode or the getting-in/off mode is detected by the state detection sensor 1810b. When the vehicle body 1801 is in the traveling mode, a control device 1850 provided in the vehicle body 1801 controls the vehicle such that the door part 1811 is not opened and closed. Further, when the vehicle body 1801 is in the getting-in/off mode, the control device 1850 controls the vehicle to limit traveling. In this case, it is preferable that the vehicle is controlled to be capable of traveling at a speed equal to or lower than a predetermined speed (for example, a speed at which the vehicle can travel in a parking lot) while the vehicle body is in the getting-in/off mode. Accordingly, the vehicle can travel in the parking lot while the vehicle body is in the getting-in/off mode.

In addition, in a case where an obstacle (the ceiling of the parking lot, or the like) present above the vehicle body 1801 is detected by the upper detection sensor 1810c when the vehicle body 1801 is to be transformed from the traveling mode into the getting-in/off mode, the control device 1850 controls the vehicle to limit the transformation of the vehicle body 1801. Accordingly, it is possible to suppress interference with the obstacle, which is present above, when the vehicle body 1801 is transformed from the traveling mode into the getting-in/off mode.

The door part 1811 is, for example, an opening/closing door of a canopy type, a gull wing type, a scissor door type, or the like and is mounted on the vehicle body-outer wall part 1810 to be rotationally movable.

The door part 1811 is mounted to be openable and closable with respect to the rear end portion of the vehicle body-outer wall part 1810. The door part 1811 can be opened and closed in the getting-in/off mode. When the front end portion of the door part 1811 flips upward, the door part 1811 is opened and an occupant can get in and off the vehicle.

The tire link part 1814 is to switch the vehicle body 1801 between the traveling mode and the getting-in/off mode, and one end portion of the tire link part 1814 is mounted on the vehicle body-outer wall part 1810 to be rotationally movable and the other end thereof is fixed to the rear tires 1813.

The tire link part 1814 is rotationally moved to a position at which the rear tires 1813 are close to the front tires 1812 by a motor (not shown), so that the vehicle body 1801 is switched between the traveling mode and the getting-in/off mode.

The display device 1830 is a touch panel type display that allows an occupant to check the surroundings of the vehicle body 1801. The display device 1830 displays a video acquired from a camera (not that images the shown) surroundings of the vehicle body 1801. Further, when an occupant sets a destination using a touch panel, the vehicle V19 can be autonomously driven.

Meanwhile, when the vehicle body 1801 is in the getting-in/off mode, the display device 1830 may be made optically transparent so that a field of view in front of an occupant seated in the vehicle seat 1802 is not blocked by the display device 1830.

The storage device 1840 is a trunk in which occupant's baggage can be stored. The storage device 1840 includes a storage part 1841 in which occupant's baggage is placed, a storage rotating part 1842 that allows the storage part 1841 to rotationally move with respect to the vehicle body-outer wall part 1810, and a storage link part 1843 that holds a placement surface of the storage part 1841 having rotationally moved at a position at which the placement surface is held horizontal.

The storage part 1841 is moved from the interior space of the vehicle body 1801 to the exterior space when the vehicle body 1801 is transformed from the traveling mode into the getting-in/off mode.

The storage rotating part 1842 allows the storage part 1841 to be rotationally moved by the driving of a motor in response to an occupant' operation. When the vehicle body 1801 is transformed from the traveling mode into the getting-in/off mode, the storage rotating part 1842 allows the storage part 1841 to rotationally move to a position at which the stored baggage can be taken in and out in conjunction with the transformation of the vehicle body 1801 from the traveling mode to the getting-in/off mode.

The control device 1850 provided in the vehicle body 1801 controls the storage rotating part 1842 such that the placement surface of the storage part 1841 is kept in a horizontal state by a horizontal sensor detecting a horizontal state when the vehicle body 1801 is transformed from the traveling mode into the getting-in/off mode.

Accordingly, for example, in a case where a cup containing beverage is placed in the storage part 1841 in the traveling mode, it is possible to suppress the spilling of the beverage contained in the cup when the vehicle body 1801 is transformed into the getting-in/off mode.

As shown in FIGS. 37 and 38, the vehicle seat 1802 includes a seat body 1820 that includes a seat back, a seat cushion, and a footrest, a seat drive device 1821 that allows the seat body 1820 to be rotatably mounted on a bottom of the vehicle body-outer wall part 1810, and a seat transformation device 1822 that changes the shape of the seat body 1820.

The seat drive device 1821 allows the seat body 1820 to rotationally move between a traveling position at which the seat body 1820 lies down when the vehicle body 1801 is in the traveling mode and a getting-in/off position at which the seat body 1820 stands up when the vehicle body 1801 is in the traveling mode.

The seat transformation device 1822 changes angles of the seat back and the footrest with respect to the seat cushion. Specifically, when the seat body 1820 is in the getting-in/off position, the seat body 1820 is brought into a state (the shape of a bed substantially flat in a horizontal direction) where the angles of the seat back and the footrest with respect to the seat cushion are changed to about 180 degrees by the seat transformation device 1822. When the seat body 1820 is in the traveling position, the seat body 1820 is brought into a state (the shape of a chair in which an occupant can be seated) where the angles of the seat back and the footrest with respect to the seat cushion are changed to about 90 degrees by the seat transformation device 1822.

Since the seat body 1820 is rotationally moved in accordance with the form of the vehicle body 1801 by the seat drive device 1821 as described above, it is possible to obtain the vehicle seat 1802 where an occupant easily gets in and off while making the vehicle body 1801 compact in size.

In addition, since the seat body 1820 is transformed in accordance with the form of the vehicle body 1801 by the seat transformation device 1822, it is possible to suppress the slip-down of an occupant's body from the seat body 1820 when the seat body 1820 rotationally moves from the traveling position to the getting-in/off position.

A modification example of the vehicle V19 will be described below.

A modification example shown in FIG. 39 is mainly different from FIG. 38 in terms of the configuration of a storage device 1840.

The storage device 1840 includes a storage part 1841 fixed to the tire link part 1814. When the vehicle body 1801 is transformed from the traveling mode into the getting-in/off mode, the storage part 1841 is moved from the interior space of the vehicle body 1801 to the exterior space with the rotational movement of the tire link part 1814.

When the vehicle body 1801 is transformed from the traveling mode into the getting-in/off mode as described above, it is possible to move the storage part 1841 to a position where stored baggage can be taken in and out with a simple configuration.

Twentieth Embodiment

Next, a vehicle V20 according to a twentieth embodiment will be described with reference to FIG. 40.

Meanwhile, the repeated description of the same contents as the vehicles V1 to V19 described above will be omitted.

The vehicle V20 according to the twentieth embodiment is mainly different from the vehicles V1 to V19 in terms of the configuration of a vehicle body 1901.

The vehicle body 1901 includes a vehicle body-outer wall part 1910 that partitions off an interior space of the vehicle body 1901 from an exterior space of the vehicle body, a door part 1911 that allows an occupant to get in and off the vehicle, front tires 1912, rear tires 1913, a tire link part 1914 that is mounted on a middle portion of the vehicle body-outer wall part 1910 in a longitudinal direction, a display device 1930 that is mounted on the inside of the door part 1911, and a storage device 1940 that is mounted on the tire link part 1914 to be rotationally movable.

The vehicle body-outer wall part 1910 is divided into two parts at the middle portion in the longitudinal direction. A front vehicle body part 1910A provided on a front side and a rear vehicle body part 1910B provided on a rear side are connected to each other by the tire link part 1914.

Meanwhile, the vehicle body-outer wall part 1910 includes a charging unit 1910a, a detection sensor 1910b that detects a state where the vehicle body-outer wall part 1910 is divided into two parts, and an upper detection sensor 1910c that is provided at a position corresponding to an upper end portion in the getting-in/off mode and detects an obstacle present above the vehicle body 1901.

The front vehicle body part 1910A is provided with a door part 1911, the front tires 1912, and a display device 1930. Further, a vehicle seat 1902 is disposed in an interior space of the front vehicle body part 1910A.

The rear vehicle body part 1910B is provided with the rear tires 1913. Further, a storage device 1940 is disposed in an interior space of the rear vehicle body part 1910B.

The storage device 1940 includes a storage part 1941 fixed in the interior space of the rear vehicle body part 1910B. When the vehicle body 1901 is transformed from a traveling mode into a getting-in/off mode, the storage part 1941 is moved to a position where stored baggage can be taken in and out with the rotational movement of the tire link part 1914.

When the vehicle body 1901 is transformed from the traveling mode into the getting-in/off mode as described above, it is possible to move the storage part 1941 to a position where stored baggage can be taken in and out with a simple configuration.

Twenty-First Embodiment

Next, a vehicle V21 according to a twenty-first embodiment will be described with reference to FIG. 41.

Meanwhile, the repeated description of the same contents as the vehicles V1 to V20 described above will be omitted.

The vehicle V21 according to the twenty-first embodiment is mainly different from the vehicles V1 to V20 in terms of the configuration of a vehicle body 2001.

The vehicle body 2001 includes a vehicle body-outer wall part 2010 that partitions off an interior space of the vehicle body 2001 from an exterior space of the vehicle body, a door part 2011 that allows an occupant to get in and off the vehicle, front tires 2012, rear tires 2013, a door drive unit 2014 that is mounted on a front portion of the vehicle body-outer wall part 2010 in a longitudinal direction, a display device 2030 that is mounted on the inside of the door part 2011, and a storage device 2040 that is mounted in an interior space of the vehicle body-outer wall part 2010.

In this embodiment, the positions of the front tires 2012 and the rear tires 2013 with respect to the vehicle body-outer wall part 2010 are fixed.

The door part 2011 is mounted to be openable and closable with respect to the vehicle body-outer wall part 2010, and is mounted on a front end portion of the vehicle body-outer wall part 2010.

The door drive unit 2014 allows the door part 2011 to rotationally move to switch the door part 2011 between a traveling position and a getting-in/off position. When the door part 2011 is in the traveling position, the door part 2011 is disposed at a position where the door part 2011 is closed with respect to the vehicle body-outer wall part 2010. When the door part 2011 is in the getting-in/off position, a rear end portion of the door part 2011 is moved upward, so that the interior space of the vehicle body 2001 is opened. Meanwhile, a front end portion of the door part 2011 may be moved upward, so that the interior space of the vehicle body 2001 may be opened.

As shown in FIG. 41, the rear end portion of the door part 2011 is moved upward by the door drive unit 2014, so that the door part 2011 is opened and an occupant can get in and off the vehicle. A state where the door part 2011 is in the traveling position is the getting-in/off mode of the vehicle body 2001, and a state where the door part 2011 is in the getting-in/off position is the getting-in/off mode of the vehicle body 2001.

An upper detection sensor 2011a is mounted on the rear end portion of the door part 2011. In a case where an obstacle (for example, the ceiling of a parking lot, or the like) present above the vehicle body 2001 is detected by the upper detection sensor 2011a when the vehicle body 2001 is to be transformed into the getting-in/off mode, the control device 2050 controls the vehicle to limit the transformation of the vehicle body 2001. Accordingly, it is possible to suppress interference with the obstacle, which is present above, when the vehicle body 2001 is transformed from the traveling mode into the getting-in/off mode.

A seat drive device 2021 allows a seat body 2020 to rotationally move between a traveling position at which the seat body 2020 lies down when the vehicle body 2001 is in the traveling mode and a getting-in/off position at which the seat body 2020 stands up when the vehicle body 2001 is in the traveling mode.

A seat transformation device 2022 changes angles of a seat back and a footrest with respect to a seat cushion. Specifically, when the seat body 2020 is in the getting-in/off position, the seat body 2020 is brought into a state (the shape of a bed substantially flat in a horizontal direction) where the angles of the seat back and the footrest with respect to the seat cushion are changed to about 180 degrees by the seat transformation device 2022. When the seat body 2020 is in the traveling position, the seat body 2020 is brought into a state (the shape of a chair in which an occupant can be seated) where the angles of the seat back and the footrest with respect to the seat cushion are changed to about 90 degrees by the seat transformation device 2022.

Since the seat body 2020 is rotationally moved in accordance with the form of the vehicle body 2001 by the seat drive device 2021 as described above, it is possible to obtain the vehicle seat 2002 where an occupant easily gets in and off while making the vehicle body 2001 compact in size.

In addition, since the seat body 2020 is transformed in accordance with the form of the vehicle body 2001 by the seat transformation device 2022, it is possible to suppress the slip-down of an occupant's body from the seat body 2020 when the seat body 2020 rotationally moves from the traveling position to the getting-in/off position.

Twenty-Second Embodiment

Next, a vehicle V22 according to a twenty-second embodiment will be described with reference to FIG. 42.

Meanwhile, the repeated description of the same contents as the vehicles V1 to V21 described above will be omitted.

As shown in FIG. 42, the vehicle V22 includes a vehicle body 2101, a vehicle seat 2102 that is disposed in an interior space of the vehicle body 2101, a battery 2103 for driving a vehicle that supplies electric power to an electric motor, a heat sink 2104 that dissipates the heat of the battery 2103, and a seat-air conditioner 2130.

As shown in FIG. 42, the vehicle body 2101 includes a vehicle body-outer wall part 2110 that partitions off an interior space of the vehicle body 2101 from an exterior space of the vehicle body and a vehicle body floor 2115 on which a vehicle seat 2 is disposed. The vehicle body-outer wall part 2110 includes a vehicle body-bottom wall portion 2111, a vehicle body-upper wall portion 2112, a vehicle body-front wall portion 2113, a vehicle body-rear wall portion 2114, and vehicle body-side wall portions 2116.

The vehicle body-bottom wall portion 2111 is to partition off the interior space from the exterior space at a lower portion of the vehicle V22. Equipments, such as the battery 2103, the heat sink 2104, the seat-air conditioner 2130, an ECU of an automatic driving control device, and harness, are arranged on the vehicle body-bottom wall portion 2111.

The heat sink 2104 is a plurality of fins provided on an upper surface of the battery 2103. The heat sink 2104 is connected to a blower passage 2133 of the seat-air conditioner 2130, and radiates heat generated from the battery 2103 to the blower passage 2133.

The seat-air conditioner 2130 includes a first blower body 2131 that sends air to a seat body 2120, a second blower body 2132 that sends air to the outside of the vehicle body 2101, a blower passage 2133 that allows air heated by heat radiated from the heat sink 2104 to pass therethrough, and a cabin-connecting passage 2134 that allows air to pass from the first blower body 2131 to the seat body 2120.

The first blower body 2131 is disposed below the seat body 2120, and discharges air, which is heated in the blower passage 2133, toward the seat body 2120.

Further, the first blower body 2131 sucks air in a passenger compartment of the vehicle body 2101 (a space surrounded by the vehicle body-upper wall portion 2112, the vehicle body-front wall portion 2113, the vehicle body-rear wall portion 2114, the vehicle body floor 2115, and the vehicle body-side wall portions 2116).

As described above, the first blower body 2131 can be switched between a state where air heated in the blower passage 2133 is discharged toward the seat body 2120 and a state where air in the passenger compartment of the vehicle body 2101 is sucked.

The second blower body 2132 is to discharge air, which is heated in the blower passage 2133, to the outside, and is disposed at a rear portion of the vehicle body-outer wall part 2110.

The blower passage 2133 is a hollow pipe member extending in the front to rear direction of the vehicle body 2101, a front end portion of the blower passage 2133 is connected to the vehicle body-front wall portion 2113, and a rear end portion thereof is connected to the vehicle body-rear wall portion 2114.

An openable and closable lid 2133a is provided at the front end portion of the blower passage 2133. When the lid 2133a is opened, air flows in from the outside. Accordingly, even though the first blower body 2131 or the second blower body 2132 is not driven, air in the passenger compartment can be sucked and can be discharged from the rear end portion of the blower passage 2133.

As shown in FIG. 42, the vehicle seat 2102 includes a seat body 2120 that includes a seat back 2121 and a seat cushion 2122.

A cushion ventilation channel 2122a that allows air from the first blower body 2131 to pass therethrough is formed in the seat cushion 2122. Air sent from the first blower body 2131 passes through the cushion ventilation channel 2122a and is blown out from blow-out ports provided on the surface of the seat cushion 2122 toward a seated occupant.

When a temperature in the passenger compartment of the vehicle body 2101 is low, a control device provided in the vehicle body 2101 controls the first blower body 2131 to drive the first blower body 2131 and to send air, which is heated in the blower passage 2133, toward the seat body 2120.

When a temperature in the passenger compartment of the vehicle body 2101 is appropriate, the control device controls the second blower body 2132 to drive the second blower body 2132 and to discharge air, which is heated in the blower passage 2133, to the outside.

When a temperature in the passenger compartment of the vehicle body 2101 is high, the control device controls the first blower body 2131 and the second blower body 2132 to drive the first blower body 2131 and the second blower body 2132, to suck air in the passenger compartment, and to discharge the air to the outside.

Accordingly, since it is possible to heat the passenger compartment with the exhaust heat of the battery 2103 while appropriately cooling the battery 2103, it is possible to improve a power-saving effect.

Meanwhile, in a case where a lithium-air battery is used as the battery 2103, the blower passage 2133 may be used to supply oxygen. When the blower passage 2133 is used for two purposes, an energy loss can be reduced as compared to a case where the flow of air is made separately.

Twenty-Third Embodiment

Next, a vehicle V23 according to a twenty-third embodiment will be described with reference to FIG. 43.

Meanwhile, the repeated description of the same contents as the vehicles V1 to V22 described above will be omitted.

A charging system that can simultaneously charge electric vehicles has been proposed in the related art (for example, JP 2021-141648).

However, the charging system in the related art supplies electric power according to a priority, but there is a concern that an electric vehicle with a low priority may have a long waiting time for charging.

As a waiting time for charging is increased, an occupant takes a nap or snack in a passenger compartment during charging and becomes absorbed in a smartphone. For this reason, there is a concern that the occupant cannot notice the completion of charging or the occurrence of a problem in charging. Further, in a case where vehicles stay at a charging station for so long, there is a concern that other vehicles cannot be charged which causes inconvenience.

An object of the present invention is to provide a vehicle that can notify an occupant of the completion of charging or the occurrence of a problem in charging and can also allow an occupant to be considerate of other vehicles.

Further, the use of an air conditioner provided in a vehicle is usually limited during charging (for example, a power saving mode). For this reason, as a waiting time for charging is increased, there is a concern that the passenger compartment cannot be kept at a comfortable temperature.

An object of the present invention is to provide a vehicle that makes a passenger compartment as a comfortable space even during charging.

As shown in FIG. 43, the vehicle V23 includes a vehicle seat 2201, heating/cooling devices 2210, a console box 2220, a door panel 2230, and a control device 2240.

The vehicle seat 2201 includes a seat back 2202, a seat cushion 2203, and a headrest 2204.

The heating/cooling device 2210 is a rechargeable panel member that can control heating and cooling, and is formed of, for example, a Peltier element that can radiate heat by being energized in one direction and absorb heat by being energized in the other direction.

As shown in FIG. 43, a plurality of heating/cooling devices 2210 are provided, and are arranged on the vehicle seat 2201, the console box 2220, and the door panel 2230. The heating/cooling devices 2210 are detachably mounted on mounting portions that are provided on the vehicle seat 2201, the console box 2220, and the door panel 2230.

The sliding desk 2362 is provided to be switchable between a position (a solid line in FIG. 46) far from an occupant seated on the seat body 2320 and a position (a dotted line in FIG. 46) close to a seated occupant.

Accordingly, an occupant can move the sliding desk 2362 to a desired position to use the sliding desk 2362.

The vehicle seat 2302 includes the fixed storage part 2370 that is used for an occupant to store baggage.

As shown in FIG. 46, the fixed storage part 2370 is provided at a position near each seat body 2320. The fixed storage part 2370 is detachably mounted on the vehicle body-outer wall part 2310 or the vehicle body floor 2315.

Accordingly, an occupant can mount the fixed storage part 2370 at a desired position to use the fixed storage part 2370.

Twenty-Fifth Embodiment

Next, a vehicle V25 according to a twenty-fifth embodiment will be described with reference to FIG. 47.

Meanwhile, the repeated description of the same contents as the vehicles V1 to V24 described above will be omitted.

As shown in FIG. 47, a vehicle body 2401 includes a vehicle body-outer wall part 2410 that is disposed to surround a vehicle seat 2402 and a vehicle body floor 2415 on which the vehicle seat 2402 is disposed.

The vehicle body-outer wall part 2410 includes a right curved door 2411 and a left curved door 2412 as doors that allow occupants to get in and off the vehicle.

As shown in FIG. 47, each door is a curved door that bulges outward in the vehicle width direction and has a curved shape.

As shown in FIG. 47, the vehicle seat 2402 includes a seat body 2420, a rail device 2430 that supports the seat body 2420 to allow the seat body 2420 to move forward and rearward with respect to the vehicle body floor 2415, and storage parts 2440 that store occupant's baggage.

The seat body 2420 is a seat having a substantially circular shape in a top view, and includes a seat back 2421 that is provided at a center of the seat body 2420 and a doughnut-shaped seat cushion 2422 that is provided at a peripheral edge portion of the seat back 2421.

The seat back 2421 is a backrest part that supports the backs of seated occupants. The seat cushion 2422 is a seat part that supports seated occupants from below.

For example, four occupants can be seated on the seat body 2420, and the seat body 2420 includes a first seat body 2420A, a second seat body 2420B, a third seat body 2420C, and a fourth seat body 2420D. Concave portions are formed on the seat cushion 2422 at positions corresponding to the first to fourth seat bodies 2420A to 2420D so that occupants are easily seated. The number of persons who can be seated on the seat body 2420 is not limited to four.

The seat body 2420 is mounted to be rotatable with respect to the vehicle body floor 2415 about an axis parallel to the up to down direction. Each of the first to fourth seat bodies 2420A to 2420D is rotated to a driving position facing a steering wheel 2450. Each of the first to fourth seat bodies 2420A to 2420D is locked not to rotationally move to the driving position facing the steering wheel 2450. Since a position (driver seat) on the seat body 2420 facing the steering wheel 2450 can be rotated as described above, an occupant who drives the vehicle can be easily replaced.

Meanwhile, a driving-prohibited seat may be provided at a part of the seat body 2420 to prohibit an occupant not having a driver's license from driving the vehicle.

For example, in a case where the first seat body 2420A and the second seat body 2420B are set as driving-allowable seats and the third seat body 2420C and the fourth seat body 2420D are set as driving-prohibited seats in FIG. 47, each of the first seat body 2420A and the second seat body 2420B is rotated to be lockable at the driving position facing the steering wheel 2450. Further, each of the third seat body 2420C and the fourth seat body 2420D is rotated not to be lockable at the driving position facing the steering wheel 2450.

Since the driving-prohibited seat is not locked at the driving position facing the steering wheel 2450 as described above, an occupant seated in the driving-prohibited seat is prohibited from driving the vehicle. Accordingly, an occupant not having a driver's license can also be seated on the seat body 2420 together.

As shown in FIG. 47, the rail device 2430 moves the seat body 2420 in the front to rear direction as a rail operation lever is operated by an occupant.

Since the seat body 2420 is moved forward as an occupant operates the rail operation lever, the seat body 2420 serving as a driver seat can be moved to a position close to the steering wheel 2450.

Meanwhile, only a part (for example, the first seat body 2420A) of the seat body 2420 may be adapted to be separated from the seat body 2420 and to be moved to a position close to the steering wheel 2450.

Twenty-Sixth Embodiment

The door pocket 2612 is provided on the door part 2611 in a state where the door pocket 2612 is divided into front and rear parts.

The instrument panel part 2630 includes footrests 2631 that support feet of occupants seated on seat bodies 2620 from below, and a table 2632 that serves as a desk for occupants.

The footrest 2631 is mounted on the instrument panel part 2630 to be rotationally movable, and is rotationally moved to be switchable between a use position (FIG. 50) at which the footrest 2631 can support feet of an occupant and a storage position (FIG. 51) at which the footrest 2631 is stored on the side surface of the instrument panel part 2630.

As the operation button 2640 is pressed by an occupant, a footrest drive motor (not shown) is operated and the footrest 2631 is rotationally moved between the use position and the storage position.

When the footrest 2631 is in the use position, the footrest 2631 is disposed at a position higher than an occupant's chest (the position of the heart).

Meanwhile, a rearview mirror provided on a ceiling surface of the vehicle body-outer wall part 2610 facing a passenger compartment may be adapted to move up and down or to move in the right to left direction to avoid interference with the footrest 2631 when the footrest 2631 is in the use position.

Alternatively, the rearview mirror may be integrated with a windshield to avoid interference with the footrest 2631.

Meanwhile, the footrests 2631 may be adapted to move up and down or may be adapted to move in the right to left direction, instead of being adapted to rotationally move. In a case where the footrest 2631 is freely driven, the position of the footrest 2631 can be adjusted according to occupant's preference. Further, an occupant can perform exercises using the footrest 2631 by changing the disposition of the footrest 2631.

The table 2632 is mounted on the instrument panel part 2630 to be rotationally movable, and is rotationally moved to be switchable between a use position (FIG. 50) at which an occupant can use the table 2632 and a storage position (FIG. 51) at which the table 2632 is stored on the side surface of the instrument panel part 2630.

As the operation button 2640 is pressed by an occupant, a table drive motor (not shown) is operated and the table 2632 is rotationally moved between the use position and the storage position.

The operation button 2640 is a button to be pressed by an occupant, and is provided on the seat body 2620 of the vehicle seat 2602. Specifically, the operation button 2640 is mounted on a tip portion of an armrest 2623 provided on the seat body 2620.

Meanwhile, the position of the operation button 2640 is no limited to the tip portion of the armrest 2623, and the operation button 2640 may be provided separately from the vehicle body 2601 or the vehicle seat 2602 like a remote controller.

In this case, the remote controller may be stored in the door pocket 2612 of the door part 2611. Further, a pocket for storing the remote controller may be provided on the instrument panel part 2630 or on a partition that partitions off private spaces for occupants.

The steering wheel 2650 is a driving steering wheel to be operated by an occupant who drives the vehicle, and is provided on the instrument panel part 2630.

The steering wheel 2650 is provided to be switchable between a use position (FIG. 51) at which an occupant can drive the vehicle and a storage position (FIG. 50) at which the steering wheel 2650 is stored in a storage recess 2630a formed in the instrument panel part 2630.

In a case where the steering wheel 2650 is unnecessary due to autonomous driving, an occupant can store the steering wheel 2650 at the storage position. Accordingly, when the seat bodies 2620, the footrests 2631, or the table 2632 is moved, interference between the steering wheel 2650 and the seat bodies 2620, the footrests 2631, or the table 2632 can be suppressed.

Meanwhile, a position in which the steering wheel 2650 is stored is not limited to a position formed in the instrument panel part 2630. For example, the steering wheel 2650 may be moved up and down not to interfere with the seat bodies 2620, the footrests 2631, or the table 2632.

Further, when the steering wheel 2650 is in the storage position, the deployment of an airbag may be limited (the volume of the airbag to be deployed may be reduced or the deployment of the airbag may be prohibited).

Airbags are provided in the ceiling surface of the vehicle body-outer wall part 2610, which faces the passenger compartment, and the seat body 2620 and are deployed between an occupant and the windshield. In a case where the footrest 2631 is in the use position, the airbag provided in the ceiling surface is deployed. In a case where the footrest 2631 is in the storage position, the airbag provided in the seat body 2620 is deployed.

As shown in FIGS. 50 and 51, the vehicle seat 2602 includes a seat body 2620 that includes a seat back 2621 and a seat cushion 2622, an armrest 2623 that is mounted to be rotationally movable with respect to the seat back 2621, and a seat lever 2624 that is mounted on the seat cushion 2622.

The vehicle V27 includes a plurality of seat bodies 2620. Specifically, the vehicle V27 includes a right front seat body 2620A and a left front seat body 2620B disposed on the left side of the right front seat body 2620A, on the vehicle body floor 2615.

The rail device 2660 is disposed between the seat body 2620 and the vehicle body floor 2615 in the up to down direction, and allows the seat body 2620 to move with respect to the vehicle body floor 2615 in the right to left direction.

An occupant can manually move a rail operation lever to adjust the position of the seat body 2620. Meanwhile, a drive motor provided in the rail device 2660 may be operated by a button pressing operation for the operation button 2640 to adjust the position of the seat body 2620 to a desired position.

The rotating device 2670 is mounted below the seat body 2620 and allows the seat body 2620 to rotatably move with respect to the vehicle body floor 2615.

An occupant can manually move the seat lever 2624 to adjust the orientation of the seat body 2620. Meanwhile, a drive motor provided in the rotating device 2670 may be operated by a button pressing operation for the operation button 2640 to adjust the orientation of the seat body 2620 to a desired position.

When the seat bodies 2620 are to be moved inward in the right to left direction, the rail device 2660 moves the seat bodies 2620 to positions where the seat bodies 2620 are close to each other. In this case, the seat levers 2624 provided on the seat bodies 2620 are arranged at positions where the seat levers 2624 do not interfere with each other.

For example, when the seat bodies 2620 are to be moved to positions where the seat bodies 2620 are close to each other, the seat lever 2624 of the right front seat body 2620A may be stored in a concave portion formed in the seat cushion 2622 of the left front seat body 2620B and the seat lever 2624 of the left front seat body 2620B may be stored in a concave portion formed in the seat cushion 2622 of the right front seat body 2620A. Accordingly, even though the seat levers 2624 are disposed at positions where the seat levers 2624 protrude from the seat bodies 2620, the seat bodies 2620 can be moved to positions where the seat bodies 2620 are in contact with each other.

Further, when the seat bodies 2620 are to be moved outward in the right to left direction, the rail device 2660 may move the seat bodies 2620 to positions where the seat bodies 2620 are in close contact with the door parts 2611. When the door parts 2611 and the seat bodies 2620 are in close contact with each other, air-conditioning performance in an interior space of the vehicle body 2601 can be improved.

Further, since a gap is formed between the front and rear door pockets 2612, interference between the seat body 2620 and the door pockets 2612 can be suppressed when the seat body 2620 is rotated.

Furthermore, concave portions for avoiding interference may be formed on pillars of the vehicle body-outer wall part 2610 so that interference between the seat body 2620 and the pillars is avoided when the seat bodies 2620 are rotated.
