Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, unless otherwise specified, the use of the directional words such as "up, down, left, right, front, and rear" generally means "up, down, left, right, front, and rear" in a state where the vehicle seat 100 is mounted on the vehicle, and corresponds to the direction of "up, down, left, right, front, and rear" when the vehicle is normally running, and specifically, the directions of the drawings as shown in fig. 1, 2, 3, and 6 may be referred to. Upright means substantially in a vertical position and may be inclined back and forth at an angle relative to the vertical position. The terms "inside and outside" refer to the inside and outside of the profile of the relevant component. In addition, the terms "first", "second", and the like used in the embodiments of the present disclosure are for distinguishing one element from another, and have no order or importance.

As shown in fig. 1 to 7, according to one aspect of the present disclosure, there is provided a vehicle seat 100, the vehicle seat 100 including a mounting bracket 10, a seat cushion 20, a backrest 30, and a headrest 40. The mounting bracket 10 is provided below the seat cushion 20 and is used for mounting to the floor in the vehicle. The seat cushion 20 is height-adjustably provided to the mounting bracket 10. The bottom end of the backrest 30 is hinged to the mounting bracket 10, and the headrest 40 is hinged to the top end of the backrest 30. The vehicle seat 100 has a folded position and a deployed position for seating. In the folded position, the headrest 40 is folded over relative to the backrest 30, the backrest 30 is stacked on the seat cushion 20, and the seat cushion 20 is stacked on the mounting bracket 10.

As shown in fig. 1, 2, 4, and 6, in the deployed position, the backrest 30 is in the upright seating position and the headrest 40 is in the upright seating position, and the vehicle seat 100 is in a state in which a passenger sits thereon. In this folded position, the head rest 40 is folded back relative to the backrest 30, the backrest 30 is stowed against the seat cushion 20, and the seat cushion 20 is lowered to a lower height to stow against the mounting bracket 10, as shown in fig. 3. At this time, the occupied space of the vehicle seat 100 becomes small, which is beneficial to enlarging the storage space in the vehicle and is convenient for placing articles.

With the above-described technical solution, as shown in fig. 3, the backrest 30 is folded down and placed on the seat cushion 20, and the vehicle seat 100 in the folded position can significantly reduce the occupation of the vehicle space in the up-down direction. Meanwhile, the seat cushion 20 stacked on the mounting bracket 10 can make up more space for the backrest 30 to turn over downwards, and further reduce the height of the backrest 30 in the up-down direction, so that the occupation of the vehicle seat 100 in the folded position in the up-down direction on the vehicle space is further reduced, the storage space in the vehicle is enlarged, large articles can be conveniently placed in the vehicle, the utilization rate of the space in the vehicle can be improved, the vehicle can carry people and also conveniently carry objects, and the vehicle use is increased.

Further, since the headrest 40 is foldable with respect to the backrest 30, when the vehicle seat 100 is folded, the headrest 40 can be pulled to be foldable with respect to the backrest 30 as shown in fig. 3, so that the space in the vehicle front-rear direction required when the backrest 30 is folded can be reduced, and the limitation on the installation space of the vehicle seat 100 can be reduced. Moreover, since the headrest 40 is folded back with respect to the backrest 30 in the folded position, the occupation of the vehicle space in the front-rear direction can be reduced, and the storage space in the vehicle can be enlarged.

In addition, since the seat cushion 20 is stacked on the mounting bracket 10 and the backrest 30 is stacked on the seat cushion 20, the stacked folding structure increases a contact area therebetween, so that the support is more stable, thereby reliably supporting the article placed on the backrest 30. At the same time, the stacked folding structure minimizes the exposed skin of the vehicle seat 100, thereby protecting the skin of the vehicle seat 100 from being scratched by the corner of the article.

In one embodiment of the present disclosure, as shown in fig. 3, the length of the backrest 30 is greater than the length of the seat cushion 20, an angle space 50 exists below the backrest 30 and at the front side of the seat cushion 20 when the vehicle seat 100 is in the folded position, the headrest 40 is folded down with respect to the backrest 30, and the headrest 40 is accommodated in the angle space 50.

In the above technical solution, by using the length difference between the backrest 30 and the seat cushion 20, when the backrest 30 is stacked on the seat cushion 20, an angle space 50 is formed below the backrest 30 and at the front side of the seat cushion 20, and the headrest 40 is folded down to be just accommodated in the angle space 50. Therefore, when the vehicle seat 100 is in the folded position, the headrest 40 does not occupy an additional vehicle interior space in the front-rear direction nor an additional vehicle interior space in the up-down direction, so that the vehicle seat 100 in the folded position is more compact in structure, the storage space in the vehicle is further enlarged, and the utilization rate of the vehicle interior space is improved. In addition, because the headrest 40 in the folded position is located below the backrest 30, the skin on the headrest 40 can be effectively protected from being scratched by the corners of an article due to the shielding of the backrest 30.

It is understood that in other embodiments, the head rest 40 may also be folded back relative to the backrest 30 to engage the back surface of the backrest 30 above the backrest 30 when the vehicle seat 100 is in the folded position.

In one embodiment of the present disclosure, as shown in fig. 1 to 3 and 6, the seat cushion 20 includes a seat cushion frame 25 and a soft pad (not shown) mounted on an upper surface of the seat cushion frame 25. A lifting mechanism 90 is provided between the seat cushion frame 25 and the mounting bracket 10. When the vehicle seat 100 is in the folded position, the lifter mechanism 90 is lowered in height to bring the seatback 30 into abutment with the soft pad, i.e., the distance between the upper surface of the seat cushion frame 25 and the lower surface of the seatback 30 is equal to the thickness of the soft pad, so that the seatback 30 is in a horizontal state.

By providing the lifting mechanism 90, on the one hand, the seat cushion 20 can be adjusted to a suitable height when the vehicle seat 100 is in the deployed position, thereby improving the comfort of the sitting. On the other hand, when the vehicle seat 100 is in the folded position, the height of the seat cushion 20 is reduced, that is, the seat cushion frame 25 and the soft pad are together reduced along with the height of the lifting mechanism 90, so that more space is made for the backrest 30 to be folded downward, and the distance between the upper surface of the seat cushion frame 25 and the lower surface of the backrest 30 is made equal to the thickness of the soft pad. In this way, when the backrest 30 in the folded position is closely attached to the cushion, the backrest 30 can be in a horizontal state. Therefore, it is more stable when stacking an article on the backrest 30, the article is not easily dropped, and a horizontal platform of the plurality of vehicle seats 100 in the folded position, which can collectively form a stacked article, is facilitated.

In other embodiments, any other suitable structure may be employed to achieve a reduction in the height of the seat cushion 20 when the vehicle seat 100 is folded. For example, a locking mechanism may be provided at the hinge of the seat cushion 20 and the backrest 30. The locking mechanism serves to maintain the angle between the seat cushion 20 and the seatback 30 at substantially 90 °. And when the vehicle seat 100 needs to be folded, the lock mechanism is unlocked and the seat cushion 20 is lowered in height. Specifically, the seat cushion 20 is hinged to the backrest 30 through the second hinge shaft 21, the locking mechanism includes a locking pin, a plurality of first locking holes are formed in the backrest 30 around the second hinge shaft 21, and a plurality of second locking holes are correspondingly formed in the seat cushion 20. When the seat cushion 20 is rotated to the seating position, the at least one second locking hole can be aligned with the first locking hole, and after the position of the seat cushion 20 is adjusted, the locking pin simultaneously penetrates through the first locking hole and the second locking hole to lock the seat cushion 20.

In the present disclosure, the lift mechanism 90 may take any suitable configuration and shape as desired by design. In one embodiment, as shown in fig. 7, a fixed support plate 71 is provided at the hinge of the backrest 30 and the mounting bracket 10. The lower end of the fixed support plate 71 is fixedly connected with the mounting bracket 10, the upper end of the fixed support plate 71 is hinged with the backrest 30 through a first hinge shaft 31, the seat cushion framework 25 is hinged with the backrest 30 through a second hinge shaft 21, and the second hinge shaft 21 is arranged above the first hinge shaft 31. It can be appreciated that, upon folding, the seat cushion 20 rotates about the second hinge shaft 21 relative to the seatback 30, as well as rotates about the first hinge shaft 31 following the seatback 30. The second hinge shaft 21 is provided above the first hinge shaft 31 to reduce the height of the seat cushion 20 when it rotates along with the seatback 30, and at this time, the seat cushion 20 moves forward relative to the mounting bracket 10, thereby preventing interference with components located at the rear side of the seat cushion 20 and affecting the folding of the vehicle seat 100.

As shown in fig. 1 to 3 and 6, the lifting mechanism 90 may include a first link 91 and a second link 92, one end of the first link 91 is hinged to the mounting bracket 10 through a third hinge shaft 93, the other end of the first link 91 is hinged to one end of the second link 92 through a fourth hinge shaft 94, the other end of the second link 92 is fixedly connected to the bottom of the seat cushion frame 25, and the first hinge shaft 31, the second hinge shaft 21, the third hinge shaft 93 and the third hinge shaft 93 are parallel to each other. Therefore, the mounting bracket 10, the fixed support plate 71 (corresponding to a frame), the first link 91 (corresponding to a side link), the second link 92, the seat cushion frame 25 (corresponding to a link), and the backrest 30 (corresponding to a side link) between the first hinge shaft 31 and the second hinge shaft 21 constitute a planar four-bar mechanism.

Therefore, when the backrest 30 rotates relative to the first hinge shaft 31, the seat cushion 20 is rotated relative to the second hinge shaft 21, the first link 91 and the second link 92 are pushed to rotate and be overlapped, and the elevation mechanism 90 is lowered in height, so that the seat cushion 20 is overlapped on the mounting bracket 10.

With the above technical solution, since a part of the backrest 30 is a side link of the planar four-bar mechanism, the seat cushion 20 cannot rotate even when the backrest 30 does not rotate, which is convenient for keeping the backrest 30 and the seat cushion 20 in the seating position. On the contrary, when the vehicle seat 100 needs to be folded, the backrest 30 rotates and simultaneously rotates the seat cushion 20, and the lifting mechanism 90 is linked to move. Therefore, in folding the vehicle seat 100, the folding operation of the vehicle seat 100 is facilitated by stacking the backrest 30 on the seat cushion 20 and stacking the seat cushion 20 on the mounting bracket 10 only by actuating the rotation of the backrest 30. The seat cushion 20 can be switched between the seating position and the folded position stacked on the mounting bracket 10 without providing an additional driving mechanism, thereby simplifying the structural design and reducing the manufacturing cost.

In other embodiments, the lifting mechanism 90 may be another mechanism, for example, a linear motion mechanism such as a linear motor, a hydraulic cylinder, or a pneumatic cylinder may be provided between the seat cushion frame 25 and the mounting bracket 10. The linear motor, the hydraulic cylinder or the pneumatic cylinder, etc. are controlled to ascend and descend by starting the switch, thereby driving the seat cushion 20 to ascend and descend. Or the screw and nut pair is driven by the stepping motor, the nut is fixedly connected with the seat cushion 20, and the screw rotates to drive the nut to move up and down, so that the seat cushion 20 is lifted.

Alternatively, in the present disclosure, as shown in fig. 1 to 4, 6, and 7, the seat cushion 20 may include a front beam 22 and two L-shaped connecting beams 23. Two L-shaped connecting beams 23 are respectively provided on the left and right sides of the backrest 30, and the front beam 22 is connected between the two L-shaped connecting beams 23 to jointly enclose a part of the seat cushion frame 25. Specifically, a front beam 22 and a rear beam are connected between two L-shaped connecting beams 23 to enclose a frame of the seat cushion frame 25. The rear beam is disposed adjacent to the backrest 30.

As shown in fig. 7, the L-shaped connecting beam 23 may include a vertical beam section 231 and a horizontal beam section 232, the vertical beam section 231 extends upward relative to the seating surface 24 of the seat cushion 20, the horizontal beam section 232 is disposed parallel to the seating surface 24 of the seat cushion 20, and an end of the vertical beam section 231 remote from the horizontal beam section 232 is hinged to the backrest 30 by a second hinge shaft 21.

The provision of the L-shaped connecting beam 23 makes it possible to raise the height of the center of rotation (second hinge shaft 21) of the seat cushion 20 without raising the seating surface 24 of the seat cushion 20, thereby providing a sufficient space for accommodating the soft pad so as to maintain the backrest 30 in the folded position in a horizontal state while also facilitating the maintenance of the seat cushion 20 at a height for comfortable seating. During the folding of the backrest 30, a downward force in the vertical direction may be applied to the seat cushion 20 through the mullion section 231, thereby facilitating the folding of the lifting mechanism 90.

The vehicle seat 100 further includes a first latch mechanism 60, a second latch mechanism 70, and an unlock mechanism 80. The first lock mechanism 60 is used to lock the headrest 40 on the seatback 30 when the vehicle seat 100 is in the deployed position. The second lock mechanism 70 is used to lock the seatback 30 to the mounting bracket 10 when the vehicle seat 100 is in the deployed position. The unlocking mechanism 80 is used to unlock the first lock mechanism 60 to enable the headrest 40 to rotate relative to the backrest 30, and is used to unlock the second lock mechanism 70 to enable the backrest 30 to rotate relative to the mounting bracket 10. By providing the first and

second lock mechanisms

60, 70, the vehicle seat 100 can be maintained in the deployed position, i.e., the backrest 30 is substantially at 90 ° to the seat cushion 20, and the headrest 40 is flattened out above the backrest 30, thereby providing a comfortable seating experience for the occupant. By providing the unlocking mechanism 80, when the vehicle seat 100 needs to be folded, the first locking mechanism 60 and the second locking mechanism 70 can be released from the limit by the unlocking mechanism 80, thereby facilitating the subsequent folding of the headrest 40 and the backrest 30.

In the present disclosure, the first locking mechanism 60 may take any suitable configuration and shape as desired by design. In one embodiment, as shown in fig. 2 and 4, the headrest 40 may include a headrest body 41, a support bar 42, and a hinge 43. The hinge member 43 is hinged to the backrest 30, and both ends of the support rod 42 are respectively fixed to the headrest body 41 and the hinge member 43, as shown in fig. 4 and 5, and the first locking mechanism 60 includes a latch 61, a lock plate 62, a mounting plate 63, and a first elastic member 64. Specifically, the first locking mechanism 60 further includes a cover plate (not shown) covering the mounting plate 63, and an accommodating space for accommodating the latch tongue 61, the locking plate 62 and the first elastic member 64 is formed between the cover plate and the mounting plate 63. The mounting plate 63 is fixed to the backrest 30. The latch tongue 61 and the lock plate 62 are rotatably provided to the mounting plate 63, respectively. One of the latch tongue 61 and the lock plate 62 is provided with a card slot 611, and the other is provided with a latch tooth 621 that cooperates with the card slot 611. The locking tongue 61 is provided with a limiting groove 612. Both ends of the first elastic member 64 are connected to the latch tongue 61 and the latch plate 62, respectively. The first elastic element 64 and the limiting groove 612 are respectively located at the front side and the rear side of the clamping groove 611, and the first elastic element 64 is used for providing a locking force for locking the clamping groove 611 and the clamping teeth 621 in a meshing manner. When the vehicle seat 100 is in the unfolded position, the latch 621 is inserted into the latching groove 611, the support rod 42 is limited in the limiting groove 612 to limit the rotation of the headrest 40 relative to the backrest 30, and the unlocking mechanism 80 can drive the locking plate 62 to rotate to overcome the locking force provided by the first elastic member 64, so that the latch 621 is disengaged from the latching groove 611, and the support rod 42 is disengaged from the limiting groove 612, thereby unlocking the first locking mechanism 60.

The first elastic member 64 may be a compression spring, or may be a common spring, a spring plate, a hollow rubber tube, or other elastic mechanism.

Specifically, in one embodiment, as shown in fig. 5, the latch 621 is disposed on the latch plate 62, and the slot 611 is disposed on the latch tongue 61. The front end of the bolt 61 is provided with a limiting groove 612, the rear end of the bolt 61 is connected with the first end of the first elastic element 64, the front end and the rear end of the bolt 61 are respectively positioned at two sides of the rotating shaft of the bolt 61, and the clamping groove 611 is arranged at the outer edge of the bolt 61 close to the locking plate 62. The front end of the lock plate 62 is provided with a rotating shaft, the rear end of the lock plate 62 is connected with the second end of the first elastic element 64, and the latch 621 is convexly arranged on the outer edge of the lock plate 62 close to the lock tongue 61. The operating principle of the first locking mechanism 60 is generally: when the headrest 40 is in the seating position, the latch 621 is embedded in the slot 611, the compressed first elastic member 64 abuts between the lock plate 62 and the latch 61, so that the tooth surface of the latch 621 abuts against the side wall of the slot 611, and the first elastic member 64 applies a leftward thrust to the latch 61, so that the support rod 42 can be limited in the limiting groove 612. When the vehicle seat 100 needs to be folded, the unlocking mechanism 80 rotates the locking plate 62 clockwise to separate the latch 621 from the slot 611, so that the limitation on the latch 61 is removed, the locking plate 62 continues to rotate, and the latch 61 is pulled to rotate clockwise through the first elastic element 64, so that the support rod 42 is separated from the limiting groove 612, and the limitation on the support rod 42 by the limiting groove 612 is removed. At this time, the headrest 40 can be rotated with respect to the backrest 30, and the folding of the headrest 40 can be achieved.

In other embodiments, the first locking mechanism 60 may also adopt other structures, for example, the mechanism may only adopt the structure of the locking tongue 61 described above, corresponding locking holes are formed in the locking tongue 61 and the mounting plate 63, and when the headrest 40 is in the seating position, a limiting pin simultaneously penetrates through the locking holes in the locking tongue 61 and the mounting plate 63 to limit the rotation of the locking tongue 61 relative to the mounting plate 63, so that the limiting groove 612 can limit the support rod 42 therein. When the headrest 40 needs to be rotated, the limiting pin is pulled out, and the limiting of the support rod 42 can be released.

In the present disclosure, the second locking mechanism 70 may take any suitable configuration and shape as desired by design. In one embodiment, as shown in fig. 6 and 7, the second locking mechanism 70 includes a fixed support plate 71, a side plate 72, a rotating plate 73, and a second elastic member 74. The lower end of the fixed support plate 71 is fixedly connected with the mounting bracket 10, the upper end of the fixed support plate 71 is hinged with the backrest 30 through the first hinge shaft 31, the side plate 72 is fixed on the side surface of the backrest 30, the rotating plate 73 is rotatably arranged on the side plate 72, two ends of the second elastic member 74 are respectively connected with the rotating plate 73 and the side plate 72, a plurality of first teeth are arranged on the outer edge of the second end of the fixed support plate 71, a plurality of second teeth are arranged at one end, close to the fixed support plate 71, of the rotating plate 73, and two ends of the second elastic member 74 are respectively connected with the rotating plate 73 and the side plate 72 to provide locking force for enabling the first teeth and the second teeth to be locked in a meshing. When the vehicle seat 100 is in the deployed position, the first tooth and the second tooth are engaged to restrict the rotation of the seatback 30 with respect to the seat cushion 20, and the unlocking mechanism 80 can drive the rotating plate 73 to rotate to overcome the locking force provided by the second elastic member 74, and separate the first tooth and the second tooth.

The second elastic element 74 may be a tension spring, a common spring, an elastic pull rope, a spring plate or other elastic mechanisms.

Specifically, in one embodiment, as shown in fig. 7, the second teeth of the rotating plate 73 and the second elastic member 74 are respectively provided on both sides of the rotating shaft of the rotating plate 73. The rotation shaft of the rotation plate 73 is fixed to the side wall of the backrest 30 through the side plate 72. The working principle of the second locking mechanism 70 is generally: when the backrest 30 is in the seating position, the first teeth and the second teeth are engaged, the stretched second elastic member 74 is connected to the rotating plate 73 and the side plate 72, and the rotating plate 73 tends to rotate clockwise by applying a rightward pulling force to the rotating plate 73 through the second elastic member 74, so that the first teeth and the second teeth are engaged more tightly without being easily disengaged, and thus, the rotation of the backrest 30 with respect to the mounting bracket 10 can be restricted. When the vehicle seat 100 needs to be folded, the unlocking mechanism 80 overcomes the pulling force of the second elastic member 74, rotates the rotating plate 73 counterclockwise, separates the first teeth from the second teeth, releases the rotation limitation on the backrest 30, and realizes the folding of the backrest 30.

It is understood that in other embodiments, the compressed second elastic member 74 may be connected to the left side of the rotating plate 73 and the side plate 72, as long as the second elastic member 74 can apply a rightward pushing force to the rotating plate 73, so that the rotating plate 73 tends to rotate clockwise.

In other embodiments, the second locking mechanism 70 may also adopt other structures, for example, a locking mechanism as in patent CN 201310521386.6. The rotation of the backrest 30 with respect to the mounting bracket 10 is restricted by the locking mechanism. Alternatively, the fixed support plate 71 and the side walls of the backrest 30 may be provided with corresponding locking holes, and when the backrest 30 is in the seating position, the backrest 30 is maintained in the upright seating position by limiting the rotation of the backrest 30 relative to the fixed support plate 71 by passing the limit pins through the locking holes of the fixed support plate 71 and the backrest 30.

In the present disclosure, the release mechanism 80 may take any suitable configuration and shape as desired by design. In one embodiment, as shown in fig. 2 and 4-7, the unlocking mechanism 80 may include a first unlocking member 81, a second unlocking member 82, and an operating handle 83. The first unlocking member 81 includes a first cable 811, and both ends of the first cable 811 are connected to the operating handle 83 and the first locking mechanism 60, respectively. The second unlocking member 82 includes a second wire 821, and both ends of the second wire 821 are connected to the operating handle 83 and the second locking mechanism 70, respectively. Operating the operating handle 83 can pull the first cable 811 and the second cable 821 simultaneously to unlock the first locking mechanism 60 and the second locking mechanism 70, respectively.

In actual operation, when the vehicle seat 100 needs to be folded, the first cable 811 and the second cable 821 can be pulled simultaneously only by moving or rotating the operating handle 83, the first locking mechanism 60 and the second locking mechanism 70 are unlocked simultaneously, and the first locking mechanism 60 and the second locking mechanism 70 which are located at different positions do not need to be unlocked respectively, so that unlocking operation is greatly simplified, operation of a user is facilitated, and operation of the vehicle seat 100 is simple and convenient. Optionally, the first cable 811 and the second cable 821 may be made of steel wire, and the first cable 811 and the second cable 821 may be sleeved with a hose so that the first cable 811 and the second cable 821 can freely slide in the hose.

In one embodiment, specifically, as shown in fig. 4 and 5, an end of the first cable 811 is connected to the locking plate 62 in the first locking mechanism 60, and when the operating handle 83 is pulled to pull the first cable 811, the first cable 811 drives the locking plate 62 to rotate clockwise, so as to unlock the first locking mechanism 60 and turn over the headrest 40 as described above. As shown in fig. 6 and 7, an end of the second cable 821 is connected to the rotating plate 73, and when the operating handle 83 is pulled to pull the second cable 821, the second cable 821 drives the rotating plate 73 to rotate counterclockwise, so as to unlock the second locking mechanism 70 and fold the backrest 30 as described above.

It is understood that, in some embodiments, the operating handle 83 in the above embodiments may not be provided, and when it is necessary to fold the vehicle seat 100, the cables corresponding to the first and

second lock mechanisms

60 and 70 are pulled, respectively, to achieve unlocking. In other embodiments, the appropriate unlocking mechanism 80 may also be selected for different locking mechanisms, such as the locking pin and the spacing pin described above.

In one embodiment of the present disclosure, the number of the second locking mechanisms 70 is two and the two second locking mechanisms are respectively disposed on the left and right sides of the backrest 30, and the number of the second cables 821 is two and corresponds to the second locking mechanisms 70 one by one. By providing the second locking mechanism 70 on both sides of the backrest 30, the firmness of the limitation of the backrest 30 in the sitting position can be increased, so that the limitation is more reliable. Moreover, by providing the second cables 821 in one-to-one correspondence with the two second locking mechanisms 70, the number of locking mechanisms is increased without increasing the operation of unlocking the locking mechanisms. The unlocking operation of all the lock mechanisms can be realized only by operating the operating handle 83 on the backrest 30, and the operation is simple.

According to another aspect of the present disclosure, there is also provided a vehicle including the vehicle seat 100 described above, the vehicle seat 100 being mounted on the floor in the vehicle interior of the vehicle by the mounting bracket 10. Due to the fact that the vehicle seat 100 is arranged, when a vehicle needs to transport large articles, the vehicle seat 100 can be folded, the space of the original position of the vehicle seat 100 is saved, the occupation of the vehicle seat 100 in the up-down direction and the front-back direction on the vehicle space is reduced, the storage space in the vehicle is enlarged, large articles can be conveniently placed in the vehicle, the utilization rate of the space in the vehicle can be improved, the vehicle can carry people and conveniently carry articles, and the purpose of the vehicle is improved.
