Abstract

A seat assembly is provided that may include a seatback and a seat bottom. The seatback may extend generally upright. The seat bottom may be connected to the seatback and may include a frame and a seat bottom adjustment mechanism. The seat bottom adjustment mechanism may include first and second cushion pans that are movable relative to the frame and movable relative to each other between first and second configurations. The first and second cushion pans may support one or more seat cushions.

Claims

1. A seat assembly comprising:

a seatback extending generally upright; and

a seat bottom connected to the seatback and including a frame and a seat bottom adjustment mechanism having first and second cushion pans that are movable relative to the frame and movable relative to each other between first and second configurations, the first and second cushion pans supporting one or more seat cushions.

2. The seat assembly of claim 1, wherein the first cushion pan includes an aft end that is pivotably connected to the frame and a forward end that is disposed at a first vertical distance from the frame in the first configuration and a second vertical distance from the frame in the second configuration, the second vertical distance being greater than the first vertical distance.

3. The seat assembly of claim 2, wherein upward-facing edges of the first and second cushion pans cooperate to define a first angle therebetween in the first configuration and a second angle therebetween in the second configuration.

4. The seat assembly of claim 3, wherein the first angle is greater than one-hundred-eighty degrees, and the second angle is less than one-hundred-eighty degrees.

5. The seat assembly of claim 2, wherein the second cushion pan is pivotably connected to the first cushion pan.

6. The seat assembly of claim 2, wherein the first cushion pan corresponds to a rear portion of the seat bottom that is adjacent the seatback.

7. The seat assembly of claim 6, wherein the second cushion pan corresponds to a front portion of the seat bottom that is spaced apart from the seatback.

8. The seat assembly of claim 1, wherein the first and second cushion pans simultaneously move relative to each other and relative to the frame.

9. The seat assembly of claim 1, wherein the seat bottom adjustment mechanism includes a first link pivotably mounted to the frame, a second link pivotably mounted to the first link and the first cushion pan, and a third link pivotably mounted to the first link and the second cushion pan.

10. A seat assembly comprising:

a seatback extending generally upright; and

a seat bottom connected to the seatback and including a frame and a seat bottom adjustment mechanism having a cushion pan assembly that is tiltable relative to the frame between first and second positions, the cushion pan assembly having a first profile shape in the first position and a second profile shape in the second position.

11. The seat assembly of claim 10, wherein the cushion pan assembly includes first and second cushion pans that are movable relative to each other to form the first and second profile shapes.

12. The seat assembly of claim 11, wherein the first cushion pan includes an aft end that is pivotably connected to the frame and a forward end that is disposed at a first vertical distance from the frame in the first position and a second vertical distance from the frame in the second position, the second vertical distance being greater than the first vertical distance.

13. The seat assembly of claim 12, wherein upward-facing edges of the first and second cushion pans cooperate to define a first angle therebetween in the first position and a second angle therebetween in the second position.

14. The seat assembly of claim 13, wherein the first angle is greater than one-hundred-eighty degrees, and the second angle is less than one-hundred-eighty degrees.

15. The seat assembly of claim 12, wherein the second cushion pan is pivotably connected to the first cushion pan.

16. The seat assembly of claim 12, wherein the first cushion pan corresponds to a rear portion of the seat bottom that is adjacent the seatback.

17. The seat assembly of claim 16, wherein the second cushion pan corresponds to a front portion of the seat bottom that is spaced apart from the seatback.

18. The seat assembly of claim 11, wherein the first and second cushion pans simultaneously move relative to each other and relative to the frame.

19. The seat assembly of claim 11, wherein the seat bottom adjustment mechanism includes a first link pivotably mounted to the frame, a second link pivotably mounted to the first link and the first cushion pan, and a third link pivotably mounted to the first link and the second cushion pan.

20. The seat assembly of claim 10, wherein the cushion pan assembly supports one or more seat cushions.
