BACKGROUND OF THE PRESENT DISCLOSURE
Field of the Present Disclosure

The present disclosure relates to a seat for mobility, which is capable of changing in seating directions.

Description of Related Art

Mobility vehicles including vehicles, in which occupants are seated, are provided with seats to ensure convenience for the occupants. The seat allows the occupant to be seated in a comfortable posture so that the occupant does not get tired even on long trips.

The seat is fixed in position in a cabin, and the occupant needs to manually adjust positions of a cushion and a seatback.

Recently, purpose-built vehicles (PBVs) have been developed as an electric vehicle-based ground transportation means. The PBVs are moved by electric wheels that move freely in 360 degrees instead of the wheels of a vehicle. The PBVs are not only used as a means of transportation, but also to provide personalized services to passengers as they travel to their destination. The personalized design of the PBVs means that they can function as city shuttles, provide leisure spaces such as restaurants, cafes, and hotels, and may be transformed into various spaces such as hospitals, pharmacies, and other socially essential facilities. To the present end, an interior of a vehicle body may be customized by use of products modularized to suit the purpose thereof.

However, because the internal space needs to be customized for various purposes of use, it is necessary to change seating directions of seats.

However, because the seats are fixed in position, it is inconvenient to detach the seats to change the positions of the seats.

The information included in this Background of the present disclosure is only for enhancement of understanding of the general background of the present disclosure and may not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

Furthermore, the term ‘mobility’ may be referred to a mobility vehicle for helping the understanding of the present disclosure hereinafter, as an example.

As illustrated in FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5 and FIG. 6, the seat for mobility according to an exemplary embodiment of the present disclosure includes guide rails 100 provided on a floor surface, support portions 200 movably mounted on the guide rails 100, link portions 300 rotatably provided on the support portion 200, and including first connection portions 310 and second connection portions 320 spaced apart from a rotation center 330 of link portions 300, a back frame 400 tiltably provided on the support portions 200 and including first operation portions 410 to which the first connection portions 310 of the link portions 300 are rotatably engaged, and a cushion frame 500 rotatably provided on the support portions 200 and including second operation portions 510 to which the second connection portions 320 of the link portions 300 are rotatably engaged, the cushion frame 500 being configured to be rotated by the link portions 300 in conjunction with a tilting operation of the back frame 400.

The guide rail 100 is fixed to the floor surface of the internal and extends in a straight or curved shape to provide a movement route of the support portion 200.

The support portion 200 is slidably connected to the guide rail 100. A seat rail structure may be applied as the support portion 200. Therefore, a movement position of the support portion 200 may change along the guide rail 100. A position of the moved support portion 200 may be fixed by a locking structure included in the seat rail structure. Because the seat rail structure is a typical technology, a detailed description of the structure thereof will be omitted.

According to an exemplary embodiment of the present disclosure, the back frame 400 and the cushion frame 500 are provided on the support portions 200. The back frame 400 and the cushion frame 500 are connected by the link portion 300 and operate in conjunction with each other.

The link portion 300 is rotatably provided on the support portion 200 and includes the first connection portion 310 and the second connection portion 320.

The back frame 400 may be rotatably and hingedly connected to the support portion 200 and connected to the first connection portion 310 of the link portion 300 through the first operation portion 410. In an exemplary embodiment of the present disclosure, the seat is configured so that an occupant may be seated in the seat in a forward/rearward direction thereof. Therefore, pads may be applied to the front and rear surfaces of the back frame 400.

The cushion frame 500 may be rotatably and hingedly connected to the support portion 200 and connected to the second connection portion 320 of the link portion 300 through the second operation portion 510. In an exemplary embodiment of the present disclosure, the seat is configured so that the occupant may be seated in the seat in the forward/rearward direction thereof. Therefore, pads may be applied to the two opposite surfaces of the cushion frame 500.

As described above, the first connection portion 310 of the link portion 300 is connected to the first operation portion 410, and the second connection portion 320 of the link portion 300 is connected to the second operation portion 510 so that the back frame 400 and the cushion frame 500 may simultaneously rotate in conjunction with the rotation of the link portion 300 when the back frame 400 or the cushion frame 500 rotates.

As described above, according to an exemplary embodiment of the present disclosure, the state in which the occupant may seated in the seat in the two directions may be implemented by the conjunction structure between the back frame 400 and the cushion frame 500 by the link portion 300 so that the convenience of accommodation and use of the seat may be ensured.

According to an exemplary embodiment of the present disclosure, the back frame 400 may be disposed on an external surface of the support portion 200, the cushion frame 500 may be disposed on an internal surface of the support portion 200, the link portion 300 may be provided on the external surface of the support portion 200, the first connection portion 310 may extend outward and be connected to the first operation portion 410 of the back frame 400, and the second connection portion 320 may extend inward and be connected to the second operation portion 510 of the cushion frame 500.

As illustrated in FIG. 3, according to an exemplary embodiment of the present disclosure, the back frame 400 and the cushion frame 500 are provided on the support portion 200. In the instant case, the support portions 200 may be provided as a pair of support portions 200, a pair of end portions of the back frame 400 is provided on the external surfaces of the two support portions 200, and the cushion frame 500 may be disposed inside the two support portions 200 and provided on the internal surfaces of the support portions 200. Therefore, the back frame 400 and the cushion frame 500 may be provided on the support portions 200 without interfering with each other.

The link portions 300 may be respectively provided on the two support portions 200 and connected to the back frame 400 and the cushion frame 500.

Therefore, the first connection portion 310 of the link portion 300 extends outward and is connected to the first operation portion 410 of the back frame 400, and the second connection portion 320 extends inwardly, at a position at which the second connection portion 320 does not interfere with the support portion 200, and is connected to the second operation portion 510 of the cushion frame 500.

Therefore, the back frame 400 and the cushion frame 500 may be connected by the link portion 300 to operate in conjunction with each other so that the back frame 400 and the cushion frame 500 may rotate simultaneously.

Meanwhile, a lower portion of the back frame 400 may be rotatably provided on the support portion 200 to be disposed below the link portion 300, and the first operation portion 410 may be provided to be spaced apart from a point at which the support portion 200 is provided.

As illustrated in FIG. 3, FIG. 4, FIG. 5 and FIG. 6, the lower portion of the back frame 400 is rotatably and hingedly connected to the support portion 200, and a point 250 to which the support portion 200 is connected may be positioned below the link portion 300. Therefore, when the back frame 400 rotates, the link portion 300 may rotate along a rotation radius of the back frame 400, and the cushion frame 500 may also be rotated by the link portion 300.

Furthermore, the first operation portion 410 may be positioned to be spaced apart from the point 250, at which the back frame 400 is mounted on the support portion 200, to be connected to the first connection portion 310 of the link portion 300 so that the link portion 300 may be rotated by the rotation of the back frame 400 while including the same rotation radius.

Meanwhile, as may be seen from FIG. 3, a point 550 at which the cushion frame 500 is provided on the support portion 200 may be disposed to be biased toward any one side in a longitudinal direction, and the second operation portion 510 may be spaced apart from the point 550, at which the cushion frame 500 is provided on the support portion 200, in a direction in which a length of a seat frame is short, based on the point 550 at which the cushion frame 500 is provided on the support portion 200 as the point 550 at which the cushion frame 500 is provided on the support portion 200 is biased.

Because the point 550 at which the cushion frame 500 is provided on the support portion 200 is disposed to be biased as described above, the cushion frame 500 is divided into a seating surface with a large area and a seating surface with a relatively small area. In the instant case, the seating direction of the cushion frame 500 may be changed in accordance with a position at which the seating surface with the large area is deployed so that the occupant may be seated on the seating surface with the large area.

The second operation portion 510 is formed at a side of the seating surface with the small area of the cushion frame 500 in a direction in which a length of the cushion frame 500 is short. Therefore, the cushion frame 500 may rotate in conjunction with the rotation of the link portion 300 so that the occupant may be seated on the seating surface with the large area, and the link portion 300 does not interfere with the occupant.

Therefore, the direction of the seating surface with the large area of the cushion frame 500 may be changed in accordance with the direction in which the cushion frame 500 rotates in conjunction with the rotations of the back frame 400 and the link portion 300 so that the seating direction may be selectively changed between the two directions.

Meanwhile, the first connection portion 310, the first operation portion 410, the second connection portion 320, and the second operation portion 510 may be respectively configured as protrusions or slits and define insertion structures.

That is, the connection structures between the first connection portion 310 and the first operation portion 410 and the connection structures between the second connection portion 320 and the second operation portion 510 are connected to one another by the structure in which the protrusion is inserted into the slit. Therefore, the back frame 400 and the cushion frame 500 as the protrusion rotates and moves in the slit.

In the description of the present disclosure, the first connection portion 310 and the second connection portion 320 of the link portion 300 are configured as protrusions, and the first operation portion 410 of the back frame 400 and the second operation portion 510 of the cushion frame 500 are configured as slits. Of course, the first connection portion 310 and the second connection portion 320 may be configured as slits, and the first operation portion 410 and the second operation portion 510 may be configured as protrusions. The same operational principle may be applied.

Each of the slits related to the first connection portion 310, the first operation portion 410, the second connection portion 320, and the second operation portion 510 may extend to define a movement route of the protrusion.

In an exemplary embodiment of the present disclosure, the first operation portion 410 and the second operation portion 510 may be configured as slits, the first operation portion 410 extends in a longitudinal direction of the back frame 400, and the second operation portion 510 extends in a longitudinal direction of the cushion frame 500.

Therefore, in a state in which the first connection portion 310, which is configured as a protrusion, is inserted into the first operation portion 410, the back frame 400 may also rotate along the rotation radius of the link portion 300, and the tilting position of the back frame 400 may be changed in accordance with the position at which the protrusion moves in the slit.

Furthermore, in a state in which the second connection portion 320, which is configured as a protrusion, is inserted into the second operation portion 510, the cushion frame 500 may also rotate along the rotation radius of the link portion 300, and the rotation position of the cushion frame 500 may be changed in accordance with the position at which the protrusion moves in the slit.

In the case of the slit related to the first connection portion 310, the first operation portion 410, the second connection portion 320, and the second operation portion 510, in the state in which the back frame 400 and the cushion frame 500 are rotated on the lines perpendicular to the upward/downward direction, the protrusions of the first connection portion 310 and the first operation portion 410 may be positioned at uppermost end portions of the slits, and the protrusions of the second connection portion 320 and the second operation portion 510 may be positioned at lowermost end portions of the slits.

With reference to FIG. 8 and FIG. 9, in the accommodation state in which the back frame 400 and the cushion frame 500 are rotated on the lines perpendicular to the upward/downward direction, the first connection portion 310, which is the protrusion, is positioned at the uppermost end portion of the first operation portion 410, which is the slit, and the second connection portion 320, which is the protrusion, is positioned at the lowermost end portion of the second operation portion 510 which is the slit so that the back frame 400 and the cushion frame 500 may rotate in opposite directions.

Furthermore, one end portion of the link portion 300 is rotatably provided on the support portion 200, and the first connection portion 310 and the second connection portion 320 are sequentially spaced apart from each other toward the other end portion. Therefore, when the link portion 300 rotates about a rotation center 330, the rotation radius of the second connection portion 320 may be ensured to be greater than the rotation radius of the first connection portion 310. In the instant case, in the accommodation state of the back frame 400 and the cushion frame 500, one direction of the link portion 300 may be a downward direction, and the other direction of the link portion 300 may be an upward direction thereof.

Therefore, a length of the slit of each of the first connection portion 310 and the first operation portion 410 is shorter than a length of the slit of each of the second connection portion 320 and the second operation portion 510 so that the rotation amount of the cushion frame 500 may be greater than the tilting amount of the back frame 400.

That is, the length of the first operation portion 410, which is configured as the slit, is configured as a relatively short length in accordance with the movement amount of the first connection portion 310 that moves along a relatively small rotation radius so that a tilting angle of the back frame 400 may be changed to support the occupant's back.

Furthermore, the length of the second operation portion 510, which is configured as the slit, is configured as a relatively long length in accordance with the movement amount of the second connection portion 320 that moves along a relatively large rotation radius so that an angle of the cushion frame 500 may be changed so that the occupant may be seated on the cushion frame 500 in a state in which the cushion frame 500 stands upright.

As described above, according to an exemplary embodiment of the present disclosure, the rotation amounts of the back frame 400 and the cushion frame 500 may be set based on the positions of the first connection portion 310 and the second connection portion 320, which form the link portion 300, and the lengths of the second operation portion 510 and the first operation portion 410. Therefore, the back frame 400 and the cushion frame 500 may be implemented as the seat in which the occupant may be seated.

The operation of the present disclosure may be performed as follows.

In the accommodation state in which the back frame 400 and the cushion frame 500 are deployed on the perpendicular line as illustrated in FIG. 7, the first connection portion 310, which is the protrusion, is positioned at the uppermost end portion of the first operation portion 410, which is the slit, and the second connection portion 320, which is the protrusion, is positioned at the lowermost end portion of the second operation portion 510, which is the slit, as illustrated in FIG. 8 and FIG. 9.

In the instant case, when the back frame 400 rotates in any one direction as illustrated in FIG. 10, the first connection portion 310, which is the protrusion, moves downwardly in the opposite direction in the first operation portion 410, which is the slit, in accordance with the rotation of the back frame 400, as illustrated in FIG. 11 and FIG. 12. At the same time, when the first connection portion 310 moves in the first operation portion 410, the link portion 300 rotates, and the second connection portion 320, which is the protrusion, moves in the opposite direction in the second operation portion 510, which is the slit so that the cushion frame 500 rotates.

Therefore, during the tilting operation of the back frame 400, the cushion frame 500 rotates in conjunction with the back frame 400 by the link portion 300 so that the back frame 400 and the cushion frame 500 may be switched to the state in which the occupant may be seated.

Furthermore, when the back frame 400 rotates in another direction as illustrated in FIG. 13, the first connection portion 310, which is the protrusion, moves downwardly in the opposite direction in the first operation portion 410, which is the slit, in accordance with the rotation of the back frame 400, as illustrated in FIG. 14, and FIG. 15. At the same time, when the first connection portion 310 moves in the first operation portion 410, the link portion 300 rotates, and the second connection portion 320, which is the protrusion, moves in the opposite direction in the second operation portion 510, which is the slit so that the cushion frame 500 rotates.

As described above, according to an exemplary embodiment of the present disclosure, the link portion 300 rotates in accordance with the rotation direction of the back frame 400, and the cushion frame 500 rotates in conjunction with the link portion 300. Therefore, the back frame 400 and the cushion frame 500 are rotated in the opposite directions by the connection structure using the connection portion and the operation portion so that the seat posture is changed. Furthermore, the seating direction changes between the two directions in accordance with the rotation directions of the back frame 400 and the cushion frame 500 so that the convenience of use may be improved.

Meanwhile, as may be seen from FIG. 5 and FIG. 6, the back frame 400 may be rotatably provided on the support portions 200 by recliners 600.

The recliner 600 includes functions of adjusting the tilting angle of the back frame 400 and locking the back frame 400, and the back frame 400 is provided on the support portions 200 by the recliners 600 so that the tilting angle of the back frame 400 may be adjusted and fixed.

The recliner 600 may include a housing, a locking plate coupled to a rotation shaft in the housing, a fixing portion configured to restrict a relative rotation between the locking plate and the housing, an elastic portion configured to apply an elastic force to the locking plate in a direction in which the fixing portion is caught and coupled, and a lever configured to release the fixing portion. The detailed structure of the recliner 600 may be applied as various embodiments.

In the instant case, a cable may be connected to the lever so that the occupant may directly manually perform the locking or unlocking operation. Alternatively, a motor may be connected so that the locking or unlocking operation may be automated.

Meanwhile, as illustrated in FIG. 16, stoppers 210 may be formed on the support portion 200 to restrict the rotation position of the link portion 300. The stopper 210 may be formed at a position at which the link portion 300 comes into contact with the stopper 210 when the cushion frame 500 rotates at a deployment angle at which the occupant may be seated on the cushion frame 500.

The stopper 210 is configured to regulate the rotation positions of the back frame 400 and the cushion frame 500. The stopper 210 may be formed in a wedge shape on the support portion 200. The stopper 210 may be brought into contact with and supported by the link portion 300 which is rotated when the back frame 400 and the cushion frame 500 are rotated in the state in which the occupant may be seated on the back frame 400 and the cushion frame 500.

Therefore, when the link portion 300 comes into contact with the stopper 210, the rotation of the link portion 300 is restricted, the position of the link portion 300 is fixed, and the positions of the back frame 400 and the cushion frame 500 are regulated so that the positions of the back frame 400 and the cushion frame 500 may be maintained so that the occupant may be seated on the back frame 400 and the cushion frame 500.

Furthermore, the link portion 300 may come into contact with the stopper 210 and implement the support structure so that the postures of the back frame 400 and the cushion frame 500 may be stabilized.

Meanwhile, as illustrated in FIG. 16, a latch 520 may be provided on the cushion frame 500, and the latch 520 may be provided to connect the link portion 300 when the cushion frame 500 rotates at a deployment angle at which the occupant may be seated on the cushion frame 500.

The latch 520 may be provided on the second operation portion 510 and are configured to regulate the rotation positions of the back frame 400 and the cushion frame 500.

FIG. 16 illustrates the exemplary embodiment in which the second connection portion 320 is configured as a groove, and the second operation portion 510 is configured as a protrusion.

In the instant case, the latch 520 is configured to fix the position of the link portion 300 when the link portion 300 is connected. The latch 520 is provided at a position at which the latch 520 may be connected to the link portion 300 when the link portion 300 rotates in conjunction with the rotation of the cushion frame 500 when the cushion frame 500 rotates in the state in which the occupant may be seated on the cushion frame 500. The latch 520 may be provided as a single latch 520 or a plurality of latches 520. According to an exemplary embodiment of the present disclosure, because the seating direction changes between the two directions, a pair of latches 520 may be configured based on the two directions.

Therefore, when the back frame 400 and the cushion frame 500 rotate and switch to the state in which the occupant may be seated on the back frame 400 and the cushion frame 500, the link portion 300 also rotates and moves to the position at which link portion 300 may be connected to the latch 520, and the link portion 300 is fixed by being connected to the latch 520 so that the positions of the back frame 400 and the cushion frame 500 may be regulated. Therefore, the positions of the back frame 400 and the cushion frame 500 may be maintained so that the occupant may be seated on the back frame 400 and the cushion frame 500.

Meanwhile, as may be seen from FIG. 1 and FIG. 2, a headrest 420 may be provided on an upper portion of the back frame 400, and the headrest 420 may be rotatably provided on the back frame 400.

To the present end, a fixing shaft a may be provided at an upper side of the back frame 400, and the headrest 420 may be rotatably engaged to the fixing shaft. When the headrest 420 rotates by 180° about the fixing shaft a, the position of the headrest may change between the two directions. The rotation angle of the headrest 420 may be set to various angles in accordance with the implementation of the seat.

Therefore, it is possible to stably support the occupant by changing the position of the headrest 420 in accordance with the change in seating direction by the back frame 400 and the cushion frame 500.

Meanwhile, the cushion frame 500 may be divided into a plurality of cushion frames 500. Any one cushion frame 500 may be provided on the support portion 200, and the remaining cushion frames 500 may be rotatably engaged to the cushion frame 500 provided on the support portion 200.

As described above, in the state in which the cushion frame 500 includes the plurality of cushion frames 500, the cushion frames 500 may be configured to be folded or unfolded. When the cushion frames 500 are folded, the accommodation space may be reduced. When the cushion frames 500 are unfolded, the occupant may be seated. Furthermore, it is possible to optimize the seating posture of the occupant by changing angles of the cushion frames 500.
