Vehicle seat
A vehicle seat is capable of taking a stowed position in which a seat back is folded onto a seat cushion and the seat cushion together with the folded seat back is rotatably lifted away from a floor, and the vehicle seat is configured to include a support member coupled to the floor; a rotating member rotatably supported by the support member via a support shaft extending in a right-left direction; a lower rail extending in a front-rear direction and coupled at an end to the rotating member so as to be extend literally offset relative to the support shaft; an upper rail slidably supported by the lower rail and coupled to the seat cushion; a coupling device provided at a second end of the lower rail on a side toward the support shaft and capable of selectably connecting to the floor; and an urging device extending the front-rear direction and having one end coupled to the support member and a second end coupled to the lower rail on the side toward the support shaft side, wherein the urging device is configured to be expandable and contractible in a longitudinal direction thereof so as to urge the seat cushion in such a direction as to rotate about the support shaft away from the floor.
1. A vehicle seat including a seat cushion, wherein the vehicle seat is capable of taking a usable position and a stowed position in which the seat cushion is rotatably lifted away from a floor, the vehicle seat comprising:
a support member coupled to the floor;
a rotating member rotatably supported by the support member via a support shaft extending in a right-left direction;
a lower rail extending in a front-rear direction and coupled to the rotating member;
an upper rail slidably supported by the lower rail and coupled to the seat cushion;
a coupling device provided at a rear end of the lower rail and capable of selectably connecting to a striker provided on the floor; and
an urging device extending the front-rear direction and having a front end coupled to the support member and a rear end coupled to the lower rail,
wherein the urging device is configured to be expandable and contractible in a longitudinal direction thereof so as to urge the seat cushion in such a direction as to rotate about the support shaft away from the floor, and
wherein the front end of the urging device is arranged lower than an upper end of the striker.
2. The vehicle seat according to claim 1 , wherein when the vehicle seat is in the usable position, the rear end of the urging device is arranged at substantially the same height as the upper end of the striker.
3. The vehicle seat according to claim 1 , wherein the urging device is arranged leftward of a right end of the support member and rightward of a left end of the support member.
4. The vehicle seat according to claim 1 , wherein the front end of the urging device is arranged rearward of the support shaft and forward of a front end of the lower rail.
5. The vehicle seat according to claim 1 , wherein in a left-right direction, the urging device is arranged on a center side of the seat cushion rather than the coupling device.
6. The vehicle seat according to claim 1 , wherein a rear end of the lower rail is arranged rearward of the striker.
7. The vehicle seat according to claim 1 , wherein viewed from the front, the support member has a portion overlapping the lower rail.
8. The vehicle seat according to claim 1 , wherein the rear end of the urging device is coupled to the lower rail via a reinforcing member coupled to the lower rail, and
viewed from the front, the support member has a portion overlapping the reinforcing member.
9. The vehicle seat according to claim 8 , wherein the reinforcing member has a bend portion protruding away from the lower rail, and
the bend portion is arranged between the rear end of the urging device and the striker.
10. The vehicle seat according to claim 8 , wherein a rear end of the reinforcing member is arranged at substantially the same position as the striker in the front-rear direction.
11. A method of making a vehicle seat including a seat cushion, the vehicle seat being capable of taking a usable position and a stowed position in which the seat cushion is rotatably lifted away from a floor, the method comprising:
coupling a support member to the floor;
supporting a rotating member rotatably to the support member via a support shaft extending in a right-left direction;
coupling a lower rail to the rotating member, the lower rail being extending in a front-rear direction;
coupling the seat cushion to an upper rail supported slidably to the lower rail;
coupling a coupling device to a rear end of the lower rail, the coupling device being capable of selectably connecting to a striker provided on the floor; and
coupling an urging device extending the front-rear direction to the support member at a front end and the lower rail at a rear end,
wherein the urging device is configured to be expandable and contractible in a longitudinal direction thereof so as to urge the seat cushion in such a direction as to rotate about the support shaft away from the floor, and
the front end of the urging device is arranged lower than an upper end of the striker.
12. The method according to claim 11 , wherein when the vehicle seat is in the usable position, the rear end of the urging device is arranged at substantially the same height as the upper end of the striker.
13. The method according to claim 11 , wherein the urging device is arranged leftward of a right end of the support member and rightward of a left end of the support member.
14. The method according to claim 11 , wherein the front end of the urging device is arranged rearward of the support shaft and forward of a front end of the lower rail.
15. The method according to claim 11 , wherein in a left-right direction, the urging device is arranged on a center side of the seat cushion rather than the coupling device.
16. The method according to claim 11 , wherein a rear end of the lower rail is arranged rearward of the striker.
17. The method according to claim 11 , wherein viewed from the front, the support member has a portion overlapping the lower rail.
18. The method according to claim 10 , wherein the rear end of the urging device is coupled to the lower rail via a reinforcing member coupled to the lower rail, and
viewed from the front, the support member has a portion overlapping the reinforcing member.
19. The method according to claim 18 , wherein the reinforcing member has a bend portion protruding away from the lower rail, and
the bend portion is arranged between the rear end of the urging device and the striker.
20. The method according to claim 18 , wherein a rear end of the reinforcing member is arranged at substantially the same position as the striker in the front-rear direction.
