Abstract

A reclining cushion assembly for a seat includes a fixed portion and a movable portion mounted to the fixed portion. The movable portion is movable between an upright position and a reclined position. At least one reclining and locking mechanism is mounted to the fixed portion. The at least one reclining and locking mechanism is movable between a first position and a second position. The at least one reclining and locking mechanism is operable to engage the movable portion to transform the movable portion from the upright position to the reclined position.

First claim

What is claimed is:

1. A reclining cushion assembly for a seat comprising:
a fixed portion including a side plate;
a movable portion mounted to the fixed portion, the movable portion being movable between an upright position and a reclined position, wherein in the reclined position, a lower end of the movable portion is offset from a surface of the fixed portion; and
at least one reclining and locking mechanism mounted to the side plate of the fixed portion, the at least one reclining and locking mechanism being movable between a first position and a second position, wherein the at least one reclining and locking mechanism is operable to engage the movable portion to transform the movable portion from the upright position to the reclined position.

2. The reclining cushion assembly of claim 1 , wherein the movable portion is rotatable about an axis defined at an upper edge of the cushion assembly.

3. The reclining cushion assembly of claim 1 , wherein the at least one reclining and locking mechanism is rotatable about an axis.

4. The reclining cushion assembly of claim 3 , wherein the movable portion further comprises an engagement surface, and the at least one reclining and locking mechanism further comprises a cam having a surface arranged in contact with the engagement surface.

5. The reclining cushion assembly of claim 4 , wherein as the at least one reclining and locking mechanism rotates about the axis from a first position to a second position, the engagement between the engagement surface and the cam rotates the movable portion from the upright position to the reclined position.

6. The reclining cushion assembly of claim 4 , wherein the surface of the cam includes a groove and when the reclining and locking mechanism is in the second position, the engagement surface is received within the groove.

7. The reclining cushion assembly of claim 6 , wherein engagement between the groove and the engagement surface restricts movement of the cushioning assembly.

8. The reclining cushion assembly of claim 1 , wherein the fixed portion includes a rigid base affixable to a seat structure.

9. The reclining cushion assembly of claim 1 , wherein the fixed portion includes a first side plate and a second side plate disposed at opposing sides of the cushion assembly, and the at least one reclining and locking mechanism includes a first reclining and locking mechanism coupled to the first side plate and a second reclining and locking mechanism coupled to the second side plate.

10. The reclining cushion assembly of claim 9 , wherein the first reclining and locking mechanism and the second reclining and locking mechanism are operably coupled.

11. The reclining cushion assembly of claim 1 , wherein the movable portion includes a cushion attached to an insert panel.

12. The reclining cushion assembly of claim 1 , wherein when the movable portion is in the reclined position, an angle of recline is about 15 degrees.

13. A seat comprising:
a seat frame having an upper portion and a lower portion, the upper portion being movable relative to the lower portion to achieve a first angle of recline; and
a cushion assembly attached to a portion of the seat frame, the cushion assembly being movable between an upright position and a reclined position to achieve a second angle of recline, distinct from the first angle of recline; and
at least one reclining and locking mechanism operable to move the cushion assembly between the upright position and the reclined position, wherein the seat frame and the cushion assembly are independently operable.

14. The seat of claim 13 , wherein the second angle of recline is compounded with the first angle of recline.

15. The seat of claim 13 , wherein the cushion assembly is removably mounted to the seat frame.

16. A method of reclining a seat comprising:
reclining an upper portion of a seat frame relative to a lower portion of a seat frame to achieve a first angle of recline; and
operating at least one reclining and locking mechanism mounted to the seat frame and associated with a cushion assembly affixed to a portion of the seat frame, wherein operating the at least one reclining and locking mechanism moves the cushion assembly between an upright position and a recline position to achieve a second angle of recline, wherein the seat frame and the cushion assembly are independently operable.

17. The method of claim 16 , wherein the first angle of recline and the second angle of recline are compounded.
