Abstract

A seat includes a seat-bottom frame, a seat-back frame rotatable relative to the seat-bottom frame between a forward position and a rearward position, and a first wedge and a second wedge on opposite side of the seat-back frame. The first wedge extends from the seat-back frame in the forward position to the seat-bottom frame, and the second wedge extends from the seat-back frame in the rearward position to the seat-bottom frame.

First claim

What is claimed is:

1. A seat comprising:
a seat-bottom frame;
a seat-back frame rotatable relative to the seat-bottom frame between a forward position and a rearward position; and
a first wedge and a second wedge on opposite sides of the seat-back frame, the first wedge extending from the seat-back frame in the forward position to the seat-bottom frame, and the second wedge extending from the seat-back frame in the rearward position to the seat-bottom frame;
wherein the seat-bottom frame includes a seat-track bracket and a seatpan coupled to the seat-track bracket, and the seat-back frame is hingedly coupled to the seat-track bracket.

2. The seat of claim 1 , wherein a rotational range of the seat-back frame from the rearward position to the forward position is no more than 60°.

3. The seat of claim 1 , wherein the first and second wedges are a first material, the seat-bottom and seat-back frames are a second material, and a yield strength of the first material is at least as high as a yield strength of the second material.

4. The seat of claim 1 , further comprising a hinge connecting the seat-bottom frame and the seat-back frame, and the first and second wedges are aligned in a seat-forward direction with the hinge.

5. The seat of claim 1 , wherein the seat-back frame includes a side beam elongated from the seat-bottom frame, and the first and second wedges are wider in a cross-seat direction than the side beam.

6. The seat of claim 1 , wherein the seat-bottom frame includes a side beam elongated from the seat-back frame, and the first and second wedges are wider in a cross-seat direction than the side beam.

7. The seat of claim 1 , wherein the first and second wedges are fixed relative to the seat-bottom frame.

8. The seat of claim 1 , wherein the first and second wedges are integral with the seat-bottom frame.

9. The seat of claim 1 , wherein the first and second wedges are welded to the seat-bottom frame.

10. The seat of claim 1 , wherein the first and second wedge are fixed relative to the seat-back frame.

11. The seat of claim 1 , further comprising a plurality of upholstery panels covering the seat-back frame and the seat-bottom frame, wherein the upholstery panels conceal the first and second wedges.

12. The seat of claim 11 , further comprising cushioning extending between the upholstery panels and first and second wedges.

13. The seat of claim 1 , wherein the second wedge is fixedly attached to the seat-track bracket.

14. The seat of claim 1 , wherein the seatpan is adjustable relative to the seat-track bracket.

15. The seat of claim 1 , wherein the first wedge is fixedly attached to the seat-track bracket.

16. A seat comprising:
a seat-bottom frame;
a seat-back frame rotatable relative to the seat-bottom frame between a forward position and a rearward position; and
a first wedge and a second wedge on opposite sides of the seat-back frame, the first wedge extending from the seat-back frame in the forward position to the seat-bottom frame, and the second wedge extending from the seat-back frame in the rearward position to the seat-bottom frame;
wherein the seat-bottom frame includes a side beam elongated from the seat-back frame, and the first and second wedges are wider in a cross-seat direction than the side beam.

17. A seat comprising:
a seat-bottom frame;
a seat-back frame rotatable relative to the seat-bottom frame between a forward position and a rearward position; and
a first wedge and a second wedge on opposite sides of the seat-back frame, the first wedge extending from the seat-back frame in the forward position to the seat-bottom frame, and the second wedge extending from the seat-back frame in the rearward position to the seat-bottom frame;
wherein the seat-back frame includes a side beam elongated from the seat-bottom frame, and the first and second wedges are wider in a cross-seat direction than the side beam.
