Motor vehicle seat with two pivot axes
View Patent ↗A seat assembly for a motor vehicle comprises a seat cushion frame, a seatback, and a leg. The seat cushion frame has an outboard end pivotally mounted to a fixed support proximate a side wall of the vehicle, and the seatback is pivotally connected to the seat cushion frame. The leg is pivotally mounted to the inboard end of the seat cushion frame and includes a latch mechanism for securing to the vehicle floor. A brace is pivotally connected to the leg and to the fixed support proximate the side wall, so that the seat cushion frame, leg, brace and fixed support act a parallel linkage to move as a unit from a use position to a stowed position of the seat assembly. The assembly is held in the stowed position by a pin that engages the brace to prevent its pivoting relative to the fixed support.
1. A seat assembly for a motor vehicle having a load floor and a side wall, the seat assembly comprising:
a seat cushion frame having an outboard end pivotally mounted to a fixed support proximate the side wall of the vehicle, the seat cushion frame being movable between a use position and a stowed position, wherein the stowed position is generally parallel to and proximate a side wall of the vehicle;
a seatback pivotally connected to the seat cushion frame; and
a support leg pivotally mounted to an inboard end of the seat cushion frame, wherein the support leg is movable between a use position generally perpendicular to the seat cushion frame and the load floor of the vehicle for supporting the seat cushion frame and a stowed position parallel to and proximate the seat cushion frame;
a brace pivotally connecting the support leg and the fixed support, wherein the brace is pivotally connected to the support leg and the fixed support; and
a pin for engaging the brace to lock the brace in a stowed position relative to the fixed support and thereby lock the seat cushion frame in the stowed position.
2. The seat assembly of claim 1 further comprising a headrest connected to the seatback.
3. The seat assembly of claim 1 further comprising an armrest connected to the seatback.
4. The seat assembly of claim 1 wherein the support leg is latchable to the load floor of the vehicle.
5. The seat assembly of claim 1 wherein the leg is normally biased toward the stowed position.
6. The seat assembly of claim 1 , wherein the brace extends from the leg to the side wall of the vehicle.
7. The seat assembly of claim 6 wherein the brace is pivotally connected to the side wall of the vehicle.
8. A seat assembly for a motor vehicle having a load floor and a side wall, the seat assembly comprising:
a fixed seat support proximate the side wall;
a seat cushion frame having an outboard end pivotally mounted to the fixed seat support, the seat cushion frame being movable between a use position and a stowed position, wherein the stowed position is generally parallel to and proximate the side wall of the vehicle;
a support leg pivotally mounted to an inboard end of the seat cushion frame, wherein the support leg is movable between a use position generally perpendicular to the seat cushion frame and the load floor of the vehicle for supporting the seat cushion frame and a stowed position parallel to and proximate the seat cushion frame, wherein the leg is normally biased toward the stowed position; and
a brace pivotally connected to the support leg and to the fixed seat support;
wherein the seat cushion frame, the fixed seat support, the brace and the support leg are pivotally connected to form a parallel linkage, whereby moving the seat cushion frame from the use position to the stowed position causes the support leg to remain substantially parallel to the fixed support and move to the stowed position as the brace also moves to the stowed position.
