Further, the front ends of the second support links 220 are connected to the front parts of the seat rails 10 by a second rotating shaft 320, and the rear ends of the second support links 220 are connected to the lower part of the second seat frame part 120 using hinges.
Particularly, first hinge terminals 212 bent upwards are formed at the front ends of the first support links 210, first hinge brackets 112 are provided at the lower part of the first seat frame part 110, and thus, the first hinge terminals 212 and the first hinge brackets 112 overlap each other and are coupled to each other using hinge pins.
In the same manner, second hinge terminals 222 bent upwards are formed at the rear ends of the second support links 220, second hinge brackets 122 are provided at the lower part of the second seat frame part 110, and thus, the second hinge terminals 222 and the second hinge brackets 122 overlap each other and are coupled to each other using hinge pins.
Therefore, the first support links 210 are disposed to be inclined downwards from the front ends thereof connected to the first seat frame part 110 to the rear ends thereof combined with the first rotating shaft 310, the second support links 220 are disposed to be inclined downwards from the rear ends thereof connected to the second seat frame part 120 to the front ends thereof combined with the second rotating shaft 320, and thus, the first support links 210 and the second support links 220 are disposed to cross each other in an X shape.
Here, in order to easily assure the rotating trajectories of the first seat frame part 110 and the second seat frame part 120 in the forward and rearward directions as in a seesaw motion, the positions of the first hinge brackets 112 of the first seat frame part 110 hinge-coupled to the first hinge terminals 212 of the first support links 210 and the second hinge brackets 122 of the second seat frame part 120 hinge-coupled to the second hinge terminals 222 of the second support links 220 need to be varied.
For this purpose, the first hinge brackets 112 are coupled to first guide rails 114 separately mounted under the lower part of the first seat frame part 110 so as to be slidably movable, and the second hinge brackets 122 are coupled to second guide rails 124 separately mounted under the lower part of the second seat frame part 120 so as to be slidably movable.
Particularly, the first rotating shaft 310 is spline-coupled to the rear ends of the first support links 210 so as to transmit rotating force thereto, and the second rotating shaft 320 is spline-coupled to the front ends of the second support links 220 so as to transmit rotating force thereto.
Further, both ends of the first rotating shaft 310 are hinge-coupled to first support brackets 11 mounted at the rear parts of the seat rails 10, and both ends of the second rotating shaft 320 are hinge-coupled to second support brackets 12 mounted at the front parts of the seat rails 10.
Particularly, the first support brackets 11 are mounted at the rear parts of movable rails 30 mounted on stationary rails 20 so as to be movable forwards and rearwards, out of elements of the seat rails 10, and the second support brackets 12 are mounted at the front parts of the movable rails 30.
The seat for a vehicle according to the present disclosure includes a driving device configured to rotate the seat frame 100 including the first seat frame part 110 and the second seat frame part 120 forwards and rearwards as in a seesaw motion.
The driving device is connected to the first rotating shaft 310 and the second rotating shaft 320 so as to transmit rotating force thereto, the angles of inclination of the first support links 210 and the second support links 220 are adjusted due to driving of the driving device, and thereby, the seat frame 100 including the first seat frame part 110 and the second seat frame part 120 may be rotated forwards and rearwards.
For this purpose, the driving device includes a first motor 410 disposed around the first rotating shaft 310, a first gear box 412 connected to the output shaft of the first motor 410 and mounted on the first rotating shaft 310 so as to transmit rotating force thereto, a second motor 420 disposed around the second rotating shaft 320, and a second gear box 422 connected to the output shaft of the second motor 420 and mounted on the second rotating shaft 320 so as to transmit rotating force thereto.
For example, the first rotating shaft 310 may be rotated by receiving rotating force through engagement between a driving gear (not shown) provided in the first gear box 412 and a driven gear (not shown) mounted on the first rotating shaft 310, and thereby, the first support links 210 spline-coupled to the first rotating shaft 310 may be rotated forwards and rearwards.
In the same manner, the second rotating shaft 320 may be rotated by receiving rotating force through engagement between a driving gear (not shown) provided in the second gear box 422 and a driven gear (not shown) mounted on the second rotating shaft 320, and thereby, the second support links 220 spline-coupled to the second rotating shaft 320 may be rotated forwards and rearwards.
According to the present disclosure, a support plate 40 is mounted on the movable rails 30 of the seat rails 10, and a suspension device 500 configured to support the boundary between the first seat frame part 110 and the second seat frame part 120 so that the boundary between the first seat frame part 110 and the second seat frame part 120 is movable upwards and downwards is mounted on the support plate 40.
In more detail, the suspension device 500 includes, as shown in
Here, the upper end of the guide link 530 is connected to a third hinge bracket 115 formed on the lower part of the boundary between the first seat frame part 110 and the second seat frame part 120 using a hinge, and the lower end of the guide link 530 is inserted into the guide pipe 510 and connected to the upper end of the spring 520 so as to compress the spring 520.
Particularly, in order to assure the upward and downward rectilinear movement of the guide link 530, a guide hole 512 extending in the vertical direction may be formed in the guide pipe 510, and a guide pin 532 inserted into the guide hole 512 may protrude from the guide link 530.
Therefore, when the seat frame 100 including the first seat frame part 110 and the second seat frame part 120 is rotated forwards or rearwards, the boundary between the first seat frame part 110 and the second seat frame part 120 is slightly moved downwards, and in this case, the third hinge bracket 115 presses the guide link 530 of the suspension device 500 downwards, and the guide link 530 is moved downwards by a designated distance while compressing the spring 520 in the guide pipe 510.
On the other hand, when the forward or rearward rotation of the seat frame 100 including the first seat frame part 110 and the second seat frame part 120 has been completed, the boundary between the first seat frame part 110 and the second seat frame part 120 is slightly moved upwards, and in this case, the guide link 530 in the guide pipe 510 is rectilinearly moved upwards due to the elastic restoring force of the spring 520, and thus, supports the boundary between the first seat frame part 110 and the second seat frame part 120 while pushing the boundary between the first seat frame part 110 and the second seat frame part 120 upwards.
As such, when the seat frame 100 including the first seat frame part 110 and the second seat frame part 120 is rotated forwards or rearwards, or when the forward or rearward rotation of the seat frame 100 including the first seat frame part 110 and the second seat frame part 120 has been completed, the suspension device 500 supports the boundary between the first seat frame part 110 and the second seat frame part 120, thereby being capable of preventing movement of the seat frame 100 and dispersing the load of passengers.
According to the present disclosure, a first leg rest frame 130 also used as a headrest frame is mounted at the distal end of the first seat frame part 110, and a second leg rest frame 140 also used as a headrest frame is mounted at the distal end of the second seat frame part 120.
Therefore, when the first seat frame part 110 is used as a seat cushion and the second seat frame part 120 is used as a seat back, the first leg rest frame 130 may be used as a leg rest and the second leg rest frame 140 may be used as a headrest.
On the other hand, when the first seat frame part 110 is used as a seat back and the second seat frame part 120 is used as a seat cushion, the first leg rest frame 130 may be used as a headrest and the second leg rest frame 140 may be used as a leg rest.
For this purpose, the first seat frame part 110 and the second seat frame part 120 may be provided to have the same shape, and the first leg rest frame 130 and the second leg rest frame 140 may be provided to have the same shape.
Here, the first leg rest frame 130 is mounted at first mounting brackets 131, mounted at the distal end of the first seat frame part 110 by welding or the like, by a first hinge shaft 132 such that the angle of the first leg rest frame 130 is adjustable, and the second leg rest frame 140 is mounted at second mounting brackets 141, mounted at the distal end of the second seat frame part 120 by welding or the like, by a second hinge shaft 142 such that the angle of the second leg rest frame 140 is adjustable.
Further, a third gear box 134 connected to the output shaft of a third motor 133 is mounted as a driving unit configured to adjust the angle of the first leg rest frame 130 on the first hinge shaft 132 so as to transmit rotating force to the first hinge shaft 132, and a fourth gear box 144 connected to the output shaft of a fourth motor 143 is mounted as a driving unit configured to adjust the angle of the second leg rest frame 140 on the second hinge shaft 142 so as to transmit rotating force to the second hinge shaft 142.
Hereinafter, the operating flow of the seat for a vehicle having the above-described configuration according to the present disclosure will be described.
The seat for a vehicle according to the present disclosure may be adjusted so as to face the front part of the vehicle.
For this purpose, when rotation driving force of the first motor 410 of the driving device in one direction is transmitted to the first rotating shaft 310 through the first gear box 412, the first rotating shaft 310 is rotated in the corresponding direction and the front ends of the first support links 210 are rotated downwards about the rear ends thereof connected to the first rotating shaft 310 simultaneously, and thereby, the first seat frame part 110 connected to the front ends of the first support links 210 using the hinges may be rotated forwards so as to be adjusted to the position of a seat cushion on which a passenger may sit.
Simultaneously, when rotation driving force of the second motor 430 of the driving device in one direction is transmitted to the second rotating shaft 320 through the second gear box 422, the second rotating shaft 320 is rotated in the corresponding direction and the rear ends of the second support links 220 are rotated upwards about the front ends thereof connected to the second rotating shaft 320 simultaneously, and thereby, the second seat frame part 120 connected to the rear ends of the second support links 220 using the hinges may be rotated forwards so as to be adjusted to the position of a seat back over which the passenger may lean.
Therefore, as shown in
Here, when forward rotation of the seat frame 100 including the first seat frame part 110 and the second seat frame part 120 has been completed, the guide link 530 in the guide pipe 510 is rectilinearly moved upwards due to elastic restoring force of the spring 520, and thus, supports the boundary provided with the second hinge bracket 115 between the first seat frame part 110 and the second seat frame part 120 while pushing the boundary between the first seat frame part 110 and the second seat frame part 120 upwards.
Further, the first leg rest frame 130 may be spread through rotation of the first hinge shaft 132 due to driving of the third motor 133 and thus be used as a leg rest on which the passenger may put his/her legs, and simultaneously, the second leg rest frame 140 may be rotated forwards through rotation of the second hinge shaft 143 due to driving of the fourth motor 143 and thus be used as a headrest which may support the passenger's head.
As such, when the first seat frame part 110 is used as the seat cushion and the second seat frame part 120 is used as the seat back, the first leg rest frame 130 may be used as the leg rest and the second leg rest frame 140 may be used as the headrest.
The seat for a vehicle according to the preset disclosure in the state in which the seat for a vehicle is adjusted so as to face the front part of the vehicle or in the state in which the seat for a vehicle is adjusted so as to face the rear part of the vehicle, may be easily adjusted to the relaxed comfort posture as if a passenger lies down to rest.
In order to assist in understating of the present disclosure, operation of converting the seat for a vehicle from the state in which the seat for a vehicle is adjusted so as to face the front part of the vehicle, as shown in
When rotation driving force of the first motor 410 of the driving device in the other direction is transmitted to the first rotating shaft 310 through the first gear box 412, the first rotating shaft 310 is rotated in the corresponding direction and the front ends of the first support links 210 are rotated upwards about the rear ends thereof connected to the first rotating shaft 310 simultaneously, and subsequently, the first seat frame part 110 connected to the front ends of the first support links 210 using the hinges is rotated rearwards, thereby being capable of implementing tilting of the seat cushion.
Simultaneously, when rotation driving force of the second motor 430 of the driving device in the other direction is transmitted to the second rotating shaft 320 through the second gear box 422, the second rotating shaft 320 is rotated in the corresponding direction and the rear ends of the second support links 220 are rotated downwards about the front ends thereof connected to the second rotating shaft 320 simultaneously, and subsequently, the second seat frame part 120 connected to the rear ends of the second support links 220 using the hinges is rotated rearwards, thereby being capable of implementing reclining of the seat back.
Thereby, as shown in
As such, the tilting operation of the first seat frame part 110 used as the seat cushion and the reclining operation of the second seat frame part 120 used as the seat back are performed, thereby being capable of easily implementing the relaxed comfort posture as if the passenger lies down to rest.
Further, when the seat frame 100 including the first seat frame part 110 and the second seat frame part 120 is rotated rearwards so as to implement the relaxed comfort posture, the boundary between the first seat frame part 110 and the second seat frame part 120 is slightly moved downwards, and in this case, the third hinge bracket 115 presses the guide link 530 of the suspension device 500 downwards, and the guide link 530 is moved downwards by a designated distance while compressing the spring 520 in the guide pipe 510, and thus supports the seat frame 100 without movement.
The seat for a vehicle according to the present disclosure may be adjusted so as to face the rear part of the vehicle, in order to implement a facing mode in which the passenger sitting on the seat for a vehicle faces a passenger sitting on another seat for a vehicle placed just behind the seat for a vehicle.
For this purpose, when rotation driving force of the first motor 410 of the driving device in the other direction is transmitted to the first rotating shaft 310 through the first gear box 412, the first rotating shaft 310 is rotated in the corresponding direction and the front ends of the first support links 210 are rotated upwards about the rear ends thereof connected to the first rotating shaft 310 simultaneously, and thereby, the first seat frame part 110 connected to the front ends of the first support links 210 using the hinges may be rotated rearwards so as to be adjusted to the position of a seat back over which a passenger may lean.
Simultaneously, when rotation driving force of the second motor 430 of the driving device in the other direction is transmitted to the second rotating shaft 320 through the second gear box 422, the second rotating shaft 320 is rotated in the corresponding direction and the rear ends of the second support links 220 are rotated downwards about the front ends thereof connected to the second rotating shaft 320 simultaneously, and thereby, the second seat frame part 120 connected to the rear ends of the second support links 220 using the hinges may be rotated rearwards so as to be adjusted to the position of a seat cushion on which the passenger may sit.
Therefore, as shown in
Here, when rearward rotation of the seat frame 100 including the first seat frame part 110 and the second seat frame part 120 has been completed, the guide link 530 in the guide pipe 510 is rectilinearly moved upwards due to elastic restoring force of the spring 520, and thus, supports the boundary provided with the second hinge bracket 115 between the first seat frame part 110 and the second seat frame part 120 while pushing the boundary between the first seat frame part 110 and the second seat frame part 120 upwards.
Further, the first leg rest frame 130 may be rotated rearwards through rotation of the first hinge shaft 132 due to driving of the third motor 133 and thus be used as a headrest which may support the passenger's head, and simultaneously, the second leg rest frame 140 may be spread through rotation of the second hinge shaft 143 due to driving of the fourth motor 143 and thus be used as a leg rest on which the passenger may put his/her legs.
As such, when the first seat frame part 110 is used as the seat back and the second seat frame part 120 is used as the seat cushion, the first leg rest frame 130 may be used as the headrest and the second leg rest frame 140 may be used as the leg rest.
As described above, the seat frame 100 including the first seat frame part 110 and the second seat frame part 120 may be rotated forwards and rearwards as in the seesaw motion about the shaft of the vehicle in the width direction thereof using the first support links 210, the second support links 220, etc., and thus, the seat for a vehicle according to the present disclosure may be easily adjusted to the facing mode posture, in which passengers sit facing each other, the relaxed comfort posture, etc.
