Abstract

Composite components ( 22, 32 ) are described herein. An example composite component ( 22, 32 ) includes a fill material sandwiched between a first shell and a second shell. The first shell can include a cavity for receiving the fill material. The second shell can include a recessed portion extending into the cavity. The recessed portion can be configured to receive a separate component ( 16 a, 30 ) of a passenger seat ( 12 ).

First claim

That which is claimed is:

1. A seat assembly, comprising:
a base frame;
a seat spreader bracket coupled to the base frame, and supporting at least a seatback; and
a bumper device comprising (i) an outer shell, (ii) an inner shell, and (iii) a foam fill material disposed between the outer shell and the inner shell, wherein an outer surface of the inner shell is coupled to the seat spreader bracket and encloses at least a portion of the seat spreader bracket.

2. The seat assembly of claim 1 , wherein the outer shell is a first outer shell, the inner shell is a first inner shell, and the foam fill material is a first foam fill material, the seat assembly further comprising a shroud coupled to the seatback and covering at least a portion of the seatback, the shroud comprising a second outer shell and a second inner shell, with a second foam fill material disposed between the second outer shell and the second inner shell.

3. The seat assembly of claim 1 , wherein:
the outer shell comprises a cavity bounded along an inner surface of the outer shell; and
the inner shell comprises a recessed portion extending into the cavity toward the outer shell, the outer surface of the recessed portion configured to receive the seat spreader bracket and enclose at least the portion of the seat spreader bracket when the bumper device is installed on the seat spreader bracket.

4. The seat assembly of claim 1 , wherein each of the outer shell and the inner shell is formed using a thermoforming technique.

5. A device for use with a seat assembly, the device comprising:
an outer shell comprising a cavity bounded along an inner surface of the outer shell;
an inner shell comprising a recessed portion extending into the cavity toward the inner surface of the outer shell, the recessed portion configured to receive a component of the seat assembly; and
a fill material disposed within at least a portion of the cavity and extending between the outer shell and the inner shell.

6. The device of claim 5 , wherein the outer shell is formed from a thermoplastic polymer comprising a thickness of between 0.03 inches and 0.1 inches.

7. The device of claim 5 , further comprising one or more bosses attached to the outer shell, the one or more bosses used to releasably couple the device to the component of the seat assembly.

8. The device of claim 5 , wherein the fill material comprises at least one of an expanded polystyrene foam or a polyvinylidene fluoride foam.

9. The device of claim 5 , wherein the fill material has a density of between 15 kilograms per cubic meter and 40 kilograms per cubic meter.

10. The device of claim 5 , wherein the component comprises a seat spreader bracket, an armrest, or a seatback.

11. The device of claim 5 , wherein:
the outer shell comprises a first perimeter edge, with the cavity bounded by the first perimeter edge; and
the inner shell comprises a second perimeter edge, the first perimeter edge and the second perimeter edge forming a connection between the outer shell and the inner shell.

12. The device of claim 11 , wherein the connection comprises at least one of a nested connection, an adhesive connection, a bonded connection, or combinations thereof.

13. A shroud for use with a seat assembly, the shroud comprising:
an outer shell comprising;
a first cavity bounded along a first inner surface of the outer shell; and a first lip at least extending about a first portion of a first perimeter of the outer shell;

an inner shell comprising:
a second cavity bounded along a second inner surface of the inner shell; and
a second lip at least extending about a second portion of a second perimeter of the inner shell, at least one of the first lip or the second lip configured to at least partially overlap the other; and
a fill material disposed within the second cavity and extending between the outer shell and the inner shell.

14. The shroud of claim 13 , further comprising an opening configured to receive a personal entertainment device.

15. The shroud of claim 13 , further comprising a first leg, a second leg, and a space disposed between the first leg and the second leg, the space configured to receive a tray table coupled to the seat assembly.

16. The shroud of claim 13 , wherein the first lip and the second lip form a connection between the outer shell and the inner shell.

17. The shroud of claim 13 , wherein the outer shell is formed from a thermoplastic polymer comprising a thickness of between 0.03 inches and 0.1 inches.

18. The shroud of claim 13 , further comprising one or more bosses attached to the outer shell, the one or more bosses used to releasably couple the shroud to the seat assembly.

19. The shroud of claim 13 , wherein the fill material comprises at least one of an expanded polystyrene foam or a polyvinylidene fluoride foam.

20. The shroud of claim 13 , wherein the fill material has a density of between 15 kilograms per cubic meter and 40 kilograms per cubic meter.

21. The shroud of claim 13 , wherein the inner shell has a predefined rigid shape, and comprises an outer surface that is configured for mounting to a seatback.

22. The shroud of claim 13 , wherein the fill material occupies substantially all of the second cavity and extends between the first inner surface of the outer shell and the second inner surface of the inner shell.

23. A method, comprising
providing a composite component comprising an outer shell and an inner shell, with a foam fill material disposed between the outer shell and the inner shell, the composite component configured to couple to a part of a seat assembly, wherein the inner shell comprises an outer surface; and
installing the composite component on the seat assembly such that (i) the composite component detachably couples with the part of the seat assembly, and (ii) the outer surface of the inner shell encloses at least a portion of the part of the seat assembly.
