Abstract

Described are monocoque seat backs having a structural shroud with a rear panel, a top lip and two side lips positioned along edges of the rear panel to form an interior volume. A mesh suspension system is coupled to the structural shroud and suspended over an opening of the interior volume. In certain embodiments, the structural shroud may be formed of one or more of a composite, a thermoplastic resin, a thermoset resin, or a polyfuryl phenolic resin. The structural shroud is constructed to satisfy 16G criteria and FST criteria.

Claims (27)

1 . A monocoque seat back comprising:

a structural shroud comprising a rear panel, a top lip, and two side lips, the top lip and two side lips positioned along edges of the rear panel and extending forward to form an interior volume of the structural shroud, wherein the rear panel, the top lip, and the two side lips are formed of a single, continuous material; and

a mesh suspension system comprising a mesh surface directly connected to the structural shroud and suspended over an opening of the interior volume.

2 . The monocoque seat back of claim 1 , wherein the mesh suspension system extends into the interior volume when compressed.

3 . The monocoque seat back of claim 1 , wherein the mesh suspension system is coupled to the structural shroud by at least one of sonic welding, friction welding, mechanical fasteners, or chemical fasteners.

4 . The monocoque seat back of claim 1 , wherein the structural shroud comprises a composite.

5 . The monocoque seat back of claim 1 , wherein the structural shroud comprises a thermoplastic resin.

6 . The monocoque seat back of claim 1 , wherein the structural shroud comprises a thermoset resin.

7 . The monocoque seat back of claim 1 , wherein the structural shroud comprises a PFA phenolic resin.

8 . The monocoque seat back of claim 1 , wherein the structural shroud satisfies 16G criteria of FAA regulation 14 C.F.R. 25.562.

9 . The monocoque seat back of claim 1 , further comprising a stowage pocket integrally formed with the structural shroud.

10 . The monocoque seat back of claim 1 , further comprising a monitor surround integrally formed with the structural shroud.

11 . The monocoque seat back of claim 1 , wherein the structural shroud is formed by compression molding.

12 . The monocoque seat back of claim 1 , wherein the structural shroud is formed by injection molding.

13 . A monocoque seat comprising:

a mesh suspension system comprising a mesh surface directly connected to the structural shroud and suspended over an opening of the interior volume; and

a cellular cushion positioned within the interior volume between the rear panel and the mesh surface of the mesh suspension system.

14 . The monocoque seat back of claim 13 , wherein the cellular cushion comprises a variable cell size.

15 . The monocoque seat back of claim 13 , wherein the cellular cushion comprises a variable cell height.

16 . The monocoque seat back of claim 13 , wherein the cellular cushion comprises a variable cell wall thickness.

17 . The monocoque seat back of claim 13 , wherein the cellular cushion comprises at least one of a honeycomb cell, a square cell, or a circular cell.

18 . A monocoque seat back comprising:

a structural shroud comprising a rear panel, a top lip, and two side lips, the top lip and two side lips positioned along edges of the rear panel and extending forward relative to the rear panel, wherein an aft side of the rear panel forms an aft surface of the seat back, and wherein a forward side of the panel, the top lip, and the two side lips together form an interior volume of the structural shroud, wherein the rear panel, the top lip, and the two side lips are formed of a single, continuous material and the structural shroud further comprises a tray table attachment point integrated into at least one of the two side lips;

a tray table directly attached to the structural shroud at the tray table attachment point;

a mesh suspension system comprising a mesh surface directly connected to the structural shroud and suspended over an opening of the interior volume; and

a cellular cushion positioned within the interior volume between the rear panel and the mesh surface of the mesh suspension system.
