Abstract

Described is a passenger seat that includes a seat bottom assembly with a forward edge and a rear edge and a seat back assembly extending up from the rear edge of the seat bottom assembly. The seat back assembly may include a frame, a plurality of panels within a perimeter of the frame, and at least one attachment member configured to attach the plurality of panels to the frame. The seat bottom assembly may include a frame and a plurality of panels within a perimeter of the frame.

First claim

That which is claimed is:

1. A seat back assembly comprising:
a plurality of panels arranged in a vertical direction;
at least one connection member that connects adjacent panels, wherein the at least one connection member is integrally formed with each of the adjacent panels; and
a rear spine member attached to an aft side of each of the plurality of panels;
at least one suspension member,
wherein the rear spine member comprises an arc shape such that at least one panel in the vertical arrangement of the plurality of panels is disposed aft of a lowermost panel of the plurality of panels;

wherein the at least one suspension member is directly coupled to the rear spine member and the plurality of panels; and
each of the plurality of panels comprises a rectangular shape.

2. The seat back assembly of claim 1 , wherein the plurality of panels comprises at least four panels.

3. The seat back assembly of claim 1 , wherein each connection member comprises at least one of a hinge, a portion with decreased thickness, a portion with smaller cross-sectional area, and a portion made from a flexible material.

4. The seat back assembly of claim 1 , wherein the plurality of panels are not attached to one another.

5. The seat back assembly of claim 1 , wherein each suspension member comprises at least one of a spring, a box, and a cylinder.

6. The seat back assembly of claim 1 , wherein each suspension member comprises a leaf spring, wherein the leaf spring comprises (i) a connection on a rear side thereof to the rear spine member and (ii) two connections on a front side thereof to a respective panel.

7. A seat back assembly comprising:
a plurality of panels arranged in a vertical direction;
at least one connection member that connects adjacent panels, wherein the at least one connection member is integrally formed with each of the adjacent panels;
a plurality of suspension members, whereon each suspension member is directly coupled to an aft side of a respective panel; and
a rear spine member disposed on an aft side of the plurality of panels, wherein the rear spine member is directly coupled to each of the plurality of suspension members.

8. The seat back assembly of claim 7 , wherein the rear spine member comprises an arc shape such that (i) at least one panel in the vertical arrangement of the plurality of panels is disposed aft of a lowermost panel of the plurality of panels and (ii) at least one panel in the vertical arrangement of the plurality of panels is disposed aft of an uppermost panel of the plurality of panels.

9. The seat back assembly of claim 7 , wherein the plurality of panels comprises at least four panels.

10. The seat back assembly of claim 7 , wherein each connection member comprises at least one of a hinge, a portion with decreased thickness, a portion with smaller cross-sectional area, and a portion made from a flexible material.

11. The seat back assembly of claim 7 , wherein the plurality of panels are not attached to one another.

12. The seat back assembly of claim 7 , wherein each suspension member comprises at least one of a spring, a box, and a cylinder.

13. The seat back assembly of claim 7 , wherein each suspension member comprises a leaf spring, wherein the leaf spring comprises (i) a connection on a rear side thereof to the rear spine member and (ii) two connections on a front side thereof to a respective panel.

14. A passenger seat comprising:
at least one seat pan assembly; and
at least one seat back assembly, wherein each of the at least one seat back assembly comprises:
four panels arranged in a vertical direction;
at least one connection member that connects adjacent panels, wherein the at least one connection member is integrally formed with each of the adjacent panels;
four suspension members, whereon each suspension member is directly coupled to an aft side of a respective panel; and
a rear spine member disposed on an aft side of the four panels, wherein the rear spine member is directly coupled to each of the four suspension members and extends from an uppermost panel to a respective seat pan assembly.

15. The passenger seat of claim 14 , wherein a lowermost panel has a smaller height than the other three panels.

16. The passenger seat of claim 14 , wherein the rear spine member comprises an arc shape such that (i) at least one panel in the vertical arrangement of the four panels is disposed aft of a lowermost panel of the four panels and (ii) at least one panel in the vertical arrangement of the four panels is disposed aft of an uppermost panel of the four panels.

17. The passenger seat of claim 14 , wherein each connection member comprises at least one of a hinge, a portion with decreased thickness, a portion with smaller cross-sectional area, and a portion made from a flexible material.
