Abstract

A vehicle seat is movable between a seating position and a storage position to form a relatively flat horizontal load floor. The seat includes a seat bottom and a seat back. A side member extends upward from the seat bottom. The seat back is rotatably mounted on the side member such that the seat back is rotatable about a horizontally extending axis. The seat back is preferably mounted on the side member so that the seat back can be rotated or flipped around by about 180 degrees so that a seating surface and a back surface of the seat back are rotatable to a reverse position. Preferably, the side member is pivotally attached to the seat bottom and is capable of moving the seat back into a generally horizontal position to define the load floor. An optional panel can be movably attached to the seat back. The panel is movable between a first position adjacent the seat back, and an extended position extending outward from the seat back and covering the seat bottom to further extend and define the load floor.

Claims

1. A vehicle seat comprising:

a seat bottom;

a side member pivotally mounted relative to said seat bottom about a first axis; and

a seat back rotatably mounted on said side member such that said seat back is rotatable about a horizontally extending second axis;

wherein said seat back is movable between multiple reclined seating positions by movement of said seat back about said first axis;

and wherein said seat back has a seating surface on one side thereof and a back surface on the other side thereof, said seat back being rotatable about said second axis between a first position, wherein said seating surface faces forward in a vehicle in which said seat is mounted and said back surface faces rearward in the vehicle, and a second position, wherein said seating surface faces rearward in the vehicle and said back surface faces forward in the vehicle.

2. The vehicle seat of claim 1, wherein said seat back rotates about 180 degrees between said first and second positions.

3. The vehicle of claim 2, wherein said seat includes a stop for preventing further rotation of said seat back beyond about 180 degree rotational movement.

4. The vehicle seat of claim 1 further including a second side member extending upward from said seat bottom, said seat back being rotatably mounted on said second side member about said horizontally extending axis such that said seat back is positioned between said side member and said second side member.

5. The vehicle seat of claim 1, wherein said seat back is rotatably mounted on said side member about said horizontally extending axis centrally located between upper and lower ends of said seat back.

6. The vehicle seat of claim 1 further including a power actuated mechanism which can be actuated to rotate said seat back.

7. The vehicle seat of claim 1, wherein said seat back is rotatably mounted on said side member by a Geneva wheel and crank mechanism.

8. The vehicle seat of claim 1, wherein said side member is mounted on a frame of said seat bottom.

9. The vehicle seat of claim 1 wherein said side member is rotatably mounted on said seat bottom.

10. The vehicle seat of claim 1 further including a power actuated mechanism which can be actuated to rotate said side member.

11. The vehicle seat of claim 1 wherein said side member is rotatably mounted on said seat bottom by a Geneva wheel and crank mechanism.

12. The vehicle seat of claim 1 further including a mechanism connected to said seat bottom for moving said seat bottom in a fore and aft direction relative to a floor of the vehicle.

13. The vehicle seat of claim 12, wherein said mechanism includes a sliding track assembly.

14. The vehicle seat of claim 12 wherein said mechanism includes a link having a first end pivotally attached to said seat bottom, and a second end pivotally attached relative to the floor of the vehicle.

15. The vehicle seat of claim 14, wherein said mechanism moves said seat bottom between a rearward position and a forward position within the vehicle, wherein a front portion of said seat bottom is at a lower position in said forward position than when in said rearward position.

16. The vehicle seat of claim 12, wherein said mechanism is power actuated.

17. The vehicle seat of claim 1 further including an extension panel fastened to said seat back such that said extension panel is movable between a first position adjacent said seat back, and an extended position extending outward from said seat back.

18. The vehicle seat of claim 17, wherein said extension panel is pivotally attached to said seat back.

19. The vehicle seat of claim 18, wherein said extension panel is pivotally attached to an upper portion of said seat back when said seat back is in a position defining a seating position.

20. The vehicle seat of claim 17, wherein said extension panel is slidably mounted on said seat back.

21. The vehicle seat of claim 17, wherein said extension panel is movable between said first and extended positions by a power actuated assembly.

22. The vehicle seat of claim 17, wherein said seat back has a relatively flat rear surface.

23. The vehicle seat of claim 17, further including a second panel pivotally connected to said extension panel.

30. The seat back of claim 1, wherein said first end of said side member is directly pivotally mounted on a frame member of said seat bottom.

31. The seat back of claim 1, wherein said seat bottom includes a cushion for supporting an occupant, and wherein said cushion is fixed relative to said first axis.

24. A method of moving a vehicle seat from a seating position to a storage position to form a load floor comprising the steps of:

a. providing a vehicle seat including;

a seat bottom;

a side member having first and second ends, the first end pivotally attached relative to the seat bottom such that the side member is rotatable about a first axis; and

a seat back rotatably mounted to the second end of the side member such that the seat back rotates about a second axis, the seat back having a seating surface on one side thereof, and a back surface on the other side, the seat back being in a normal seating position wherein the seating surface faces forward in the vehicle and the back surface faces rearward in the vehicle;

b. rotating the seat back about the second axis such that the seating surface faces rearward in the vehicle and the back surface faces forward in the vehicle; and

c. subsequently to step (b), pivoting the side member about the first axis to move the seat back to a generally horizontal position such that the back surface faces upward, thereby forming a load floor defined by the back surface of the seat back.

25. The method of claim 24, wherein the vehicle seat includes a panel, the method further comprising the step of moving the panel from a first position adjacent the back surface of the seat back to a second movable wherein the panel extends outwardly from the seat back and positioned above the seat bottom, wherein the back surface of the seat back and the panel define the load floor.

26. The method of claim 24, wherein the panel is moved to the second position such the panel is generally co-planar with the back surface of the seat back.

27. The method of claim 24, wherein step (c) is performed subsequently to step (b).

28. The method of claim 24, wherein step (b) is performed simultaneously with step (c).

29. The method of claim 24 further providing a second seat having a seat bottom and a seat back pivotable relative to the seat bottom, the method further comprising the step of moving the seat back to a generally horizontal position such that a back surface of the seat back faces upward, wherein the back surface further defines the load floor.

32. A vehicle seat comprising:

a seat bottom;

a side member pivotally mounted relative to said seat bottom about a first axis; and

a seat back rotatably mounted on said side member such that said seat back is rotatable about a horizontally extending second axis,

wherein said seat back has a seating surface on one side thereof and a back surface on the other side thereof, said seat back being rotatable about said second axis between a first position, wherein said seating surface faces forward in a vehicle in which said seat is mounted and said back surface faces rearward in the vehicle, and a second position, wherein said seating surface faces rearward in the vehicle and said back surface faces forward in the vehicle;

wherein said seat back is movable between said first and second positions without rotational movement of said side member about said first axis.

33. The vehicle seat of claim 32, wherein said seat back rotates about 180 degrees between said first and second positions.
