Vehicular seat
View Patent ↗To be able to store a seat back and a seat cushion in line from front to back and be able to widely ensure space above a storage position of the seat cushion. In a rear seat ( 10 ), when a seat back ( 18 ) is rotated to a forwardly collapsed position in a state where a seat cushion ( 16 ) has been moved to a storage position, the seat back ( 18 ) and the seat cushion ( 16 ) are stored in parallel from front to back. Consequently, the seat back ( 18 ) and the seat cushion ( 16 ) can be thinly stored in an up-down direction of a vehicle. Moreover, the storage position of the seat cushion ( 16 ) is set on a rear lower side of a use position, so space above the storage position can be widely ensured.
1. A vehicular seat comprising:
a seat cushion for seating a passenger;
a support mechanism that is configured to include a link member, one end side of which is rotatably coupled to the seat cushion and the other end side of which is rotatably coupled to a vehicle body floor, and which supports the seat cushion with respect to the vehicle body floor, the seat cushion having a use position where a passenger is capable of sitting on the seat cushion and a storage position where the seat cushion is slid to a rear lower side of the use position, wherein a top surface of the seat cushion faces upward in both the use position and the storage position;
a seat back that is supported on the vehicle body floor such that the seat back is rotatable between an upright position where the seat back supports the back of a passenger who is seated on the seat cushion that has been disposed in the use position and a forwardly collapsed position where the seat back is disposed in line in front of the seat cushion that has been moved to the storage position; and
a holding mechanism that holds the seat cushion in the use position and is capable of releasing the seat cushion from the use position and an urging member that urges the seat cushion toward the storage position.
2. The vehicular seat according to claim 1 , wherein the link member is disposed along the vehicle body floor in a state where the seat cushion has been moved to the storage position.
3.

4. The vehicular seat according to claim 1 , wherein the one end side of the link member is coupled to a front end portion of the seat cushion, and the support mechanism includes projections that are disposed on both left and right sides of a rear end portion of the seat cushion and guide members that are disposed on both left and right sides of the seat cushion, are attached to the vehicle body floor, and in which are formed guide grooves into which the projections fit such that the projections are relatively movable.
5. The vehicular seat according to claim 4 , wherein the guide members include a pair of wall portions that face each other in a left-right direction, with the guide grooves being formed in one wall and with the seat back being supported on the other wall via a reclining mechanism that is disposed between both walls.
6. The vehicular seat according to claim 1 , wherein the storage position is set on a lower side of a deck board that configures a floor of a cargo compartment.
7. A vehicular seat comprising:
a seat cushion for seating a passenger;
a support mechanism including a link member, one end and the other sides of the link member being pivoted to the seat cushion and to a vehicle body floor, respectively, for allowing the seat cushion to move in vehicle lengthwise and height directions between a use position where a passenger is capable of sitting on the seat cushion and a storage position where the seat cushion is slid to a rear lower side of the use position, wherein a top surface of the seat cushion faces upward in both the use position and the storage position; and
a seat back that is supported on the vehicle body floor such that the seat back is rotatable between an upright position where the seat back supports the back of a passenger who is seated on the seat cushion that has been disposed in the use position and a forwardly collapsed position where the seat back is disposed in line in front of the seat cushion that has been moved to the storage position.
8. The vehicular seat according to claim 7 , wherein the link member is disposed along the vehicle body floor in a state where the seat cushion has been moved to the storage position.
9. The vehicular seat according to claim 7 , further comprising a holding mechanism that holds the seat cushion in the use position and is capable of releasing the seat cushion from the use position and an urging member that urges the seat cushion toward the storage position.
10. The vehicular seat according to claim 9 , wherein the seat cushion includes a cushion frame that serves as a skeleton member, a rod portion that configures the skeleton of the seat cushion together with the cushion frame is disposed on the one end side of the link member, one end side of the urging member is locked to the rod portion, and the other end side of the urging member is locked to the cushion frame.
11. The vehicular seat according to claim 7 , wherein the one end side of the link member is coupled to a front end portion of the seat cushion, and the support mechanism includes projections that are disposed on both left and right sides of a rear end portion of the seat cushion and guide members that are disposed on both left and right sides of the seat cushion, are attached to the vehicle body floor, and in which are formed guide grooves into which the projections fit such that the projections are relatively movable.
12. The vehicular seat according to claim 9 , wherein the guide members include a pair of wall portions that face each other in a left-right direction, with the guide grooves being formed in one wall and with the seat back being supported on the other wall via a reclining mechanism that is disposed between both walls.
13. The vehicular seat according to claim 7 , wherein the storage position is set on a lower side of a deck board that configures a floor of a cargo compartment.
14. The vehicular seat according to claim 1 , wherein the seat cushion moves into the storage position independently of the movement of the seat back into the forwardly collapsed position.
15. The vehicular seat according to claim 7 , wherein the seat cushion moves into the storage position independently of the movement of the seat back into the forwardly collapsed position.
