Abstract

Described are seat backs for passenger seats. The seat back includes a frame, and the frame includes an upper portion and a lower portion. The upper portion includes a top end of the seat back, and the lower portion is adjacent to the upper portion. A thickness of the upper portion of the frame may be less than a thickness of the lower portion of the frame.

First claim

That which is claimed is:

1 . A seat back for a passenger seat, the seat back comprising a frame, the frame comprising:
an upper portion comprising a top end of the seat back; and a lower portion adjacent to the upper portion, wherein a thickness of the upper portion of the frame is less than a thickness of the lower portion of the frame.

2 . The seat back of claim 1 , wherein the frame is tubular and defines a central cavity.

3 . The seat back of claim 2 , wherein the frame supports a back sheet, and wherein the back sheet defines a housing area in an aft side of the seat back.

4 . The seat back of claim 1 , wherein the upper portion of the frame extends vertically at a non-zero angle relative to the lower portion of the frame.

5 . The seat back of claim 1 , further comprising a reinforcing member reinforcing at least a portion of the upper portion of the frame.

6 . The seat back of claim 1 , wherein the frame comprises a metal material.

7 . A passenger seat comprising a seat back, the seat back comprising a tubular frame, the tubular frame comprising:
a forward side; an aft side; an upper portion; and a lower portion, wherein a distance from the forward side to the aft side is a thickness of the tubular frame, and wherein the thickness of the upper portion of the tubular frame is less than the thickness of the lower portion of the tubular frame.

8 . The passenger seat of claim 7 , further comprising a seat base, and wherein the seat back is joined to the seat base.

9 . The passenger seat of claim 7 , further comprising a reinforcing member joined to at least a portion of the upper portion of the tubular frame, and wherein the reinforcing member comprises at least one of a doubler and a stiffener.

10 . The passenger seat of claim 9 , wherein the reinforcing member is joined to the portion of the upper portion of the tubular frame through at least one of a mechanical fastener, welding, and an adhesive.

11 . The passenger seat of claim 7 , wherein the upper portion of the tubular frame extends vertically at a non-zero angle relative to the lower portion of the tubular frame such that the upper portion of the tubular frame extends forward relative to the lower portion of the tubular frame.

12 . The passenger seat of claim 7 , wherein the tubular frame supports a back sheet, and wherein the back sheet defines a housing area in an aft side of the seat back.

13 . The passenger seat of claim 7 , wherein the tubular frame comprises a metal material.

14 . A passenger seat comprising a seat back, the seat back comprising a hollow frame, the hollow frame comprising:
a forward side; an aft side; and a central cavity defined within the hollow frame, wherein a distance from the forward side to the aft side is a thickness of the hollow frame, and wherein at least a portion of the aft side of the hollow frame defines an aperture providing access to the central cavity.

15 . The passenger seat of claim 14 , further comprising a seat base, and wherein the seat back is joined to the seat base.

16 . The passenger seat of claim 14 , wherein the thickness of the hollow frame is from about 0.0 mm to about 70.0 mm.

17 . The passenger seat of claim 14 , further comprising a reinforcing member, wherein the reinforcing member is positionable in the aperture and is joined to the hollow frame.

18 . The passenger seat of claim 14 , wherein the hollow frame further comprises an upper portion and a lower portion, wherein the upper portion defines a top end of the seat back, and wherein the thickness of the upper portion of the hollow frame is less than the thickness of the lower portion of the hollow frame.

19 . The passenger seat of claim 18 , wherein the upper portion defines the aperture providing access to the central cavity.

20 . The passenger seat of claim 14 , wherein the entire aft side of the hollow frame defines the aperture providing access to the central cavity.
