Abstract

A seat assembly may include a seat support configured to be fixed to a first mounting portion of a mounting surface; a seatback frame having an upper portion and a lower portion; a seat base including a seat base frame rotationally connected to the seat support, and a track movably connected to the seat base frame; and a linkage connecting the lower portion of the seatback frame with the track. The upper portion of the back frame may be configured to be rotationally connected to a second mounting portion of said mounting surface.

First claim

What is claimed is:

1. A seat assembly, comprising:
a seat support configured to be connected to a first mounting portion of a mounting surface;
a seatback frame having an upper portion and a lower portion;
a seat base including:
a seat base frame rotationally connected to the seat support, and
a track movably connected to the seat base frame; and

a linkage connecting the lower portion of the seatback frame with the track;
wherein the upper portion of the seatback frame is configured to be rotationally connected to a second mounting portion of said mounting surface.

2. The seat assembly of claim 1 , wherein a seatback frame rotation axis of the seatback frame is fixed.

3. The seat assembly of claim 1 , wherein the linkage includes:
a bracket connected to the track; and
a lever rotationally connected to the bracket and rotationally connected to the lower portion of the seatback frame.

4. The seat assembly of claim 3 , wherein a first lever rotation axis of the lever is substantially fixed relative to the seatback frame such that the lever and the seatback frame can rotate relative to each other and do not substantially translate relative to each other.

5. The seat assembly of claim 4 , wherein a second lever rotation axis of the lever is substantially fixed relative to the bracket such that the lever and the bracket can rotate relative to each other and do not substantially translate relative to each other.

6. The seat assembly of claim 5 , wherein the linkage is configured such that the first lever rotation axis and the second lever rotation axis move relative to the seat support; and
a seatback frame rotation axis is substantially fixed relative to the seat support.

7. The seat assembly of claim 3 , wherein the track includes a first track portion connected to the seat base frame and includes a second track portion slidably connected to the first track portion; and
the bracket is connected to the second track portion.

8. The seat assembly of claim 7 , wherein the second track portion is configured to slide relative to the first track portion and the seat base frame to facilitate adjustment of the seatback frame.

9. The seat assembly of claim 8 , wherein the second track portion is configured to slide to a plurality of track positions relative to the first track portion;
the plurality of track positions correspond to angles of the seatback frame; and
the seat base frame is configured to rotate from a seating position to a storage position when the second track portion is in the plurality of track positions.

10. The seat assembly of claim 8 , wherein the bracket is fixed to the second track portion such that sliding movement of the second track portion causes rotation of the seatback frame about a seatback frame rotation axis that is substantially fixed proximate the upper portion of the seatback frame.

11. The seat assembly of claim 1 , wherein the seat base frame is configured to rotate relative to the seat support between a seating position and a storage position.

12. The seat assembly of claim 11 , wherein, in the storage position, the seat base frame is substantially vertical.

13. A vehicle, comprising:
said mounting surface; and
the seat assembly of claim 1 ;
wherein the seat support is substantially fixed to the first mounting portion; and
the upper portion of the seatback frame is rotationally connected to the second mounting portion.

14. The vehicle of claim 13 , wherein the seat assembly includes a headrest fixed to the second mounting portion proximate the upper portion of the seatback frame.

15. The vehicle of claim 14 , wherein the second mounting portion includes a glass portion at least partially aligned with the headrest; and
the upper portion of the seatback frame is rotationally connected to the second mounting portion such that (i) a seatback frame rotation axis is substantially fixed relative to the mounting surface, (ii) the seatback frame cannot substantially translate relative to the mounting surface, and (iii) rotation of the seatback frame does not damage the glass portion.

16. The vehicle of claim 13 , wherein the first mounting portion is substantially perpendicular to the second mounting portion.

17. The vehicle of claim 16 , wherein the first mounting portion includes a floor of the vehicle; and
the second mounting portion includes a substantially vertical wall of the vehicle.

18. The vehicle of claim 13 , wherein
the linkage includes:
a bracket connected to the track; and
a lever rotationally connected to the bracket and rotationally connected to the lower portion of the seatback frame;

a first lever rotation axis of the lever is substantially fixed relative to the seatback frame such that the lever and the seatback frame can rotate relative to each other and do not substantially translate relative to each other;
a second lever rotation axis of the lever is substantially fixed relative to the bracket such that the lever and the bracket can rotate relative to each other and do not substantially translate relative to each other;
the linkage is configured such that the first lever rotation axis and the second lever rotation axis move relative to the seat support;
a seatback frame rotation axis is substantially fixed relative to the seat support;
the track includes a first track portion connected to the seat base frame and includes a second track portion slidably connected to the first track portion;
the bracket is connected to the second track portion;
second track portion is configured to slide relative to the first track portion and the seat base frame to facilitate adjustment of the seatback frame;
the second track portion is configured to slide to a plurality of track positions relative to the first track portion;
the plurality of track positions correspond to angles of the seatback frame; and
the seat base frame is configured to move from a seating position to a storage position when the second track portion is in the plurality of track positions.

19. The vehicle of claim 18 , wherein the seat base frame is configured to move from the seating position to the storage position when the second track portion is in the plurality of track positions without the second track portion moving relative to the first track portion.

20. The vehicle of claim 18 , including a headrest connected to the second mounting portion such that the headrest does not move with the seatback frame.
