Abstract

Described are tray tables having a shroud and a core assembly. The shroud may form an outer surface of the tray table. The core assembly may be within the shroud and may include a top sheet, a bottom sheet, and a honeycomb core. The honeycomb core may be between the top sheet and the bottom sheet. The honeycomb core may define a plurality of cells.

First claim

That which is claimed is:

1 . A tray table for a passenger seat, the tray table comprising:
a shroud forming an outer surface of the tray table; and a core assembly within the shroud, the core assembly comprising:
a top sheet;
a bottom sheet; and
a honeycomb core between the top sheet and the bottom sheet, wherein the honeycomb core defines a plurality of cells.

2 . The tray table of claim 1 , wherein the top sheet, the bottom sheet, and the honeycomb core each comprise aluminum.

3 . The tray table of claim 1 , wherein a thickness of the top sheet is different from a thickness of the bottom sheet.

4 . The tray table of claim 3 , wherein the thickness of the top sheet is greater than the thickness of the bottom sheet.

5 . The tray table of claim 1 , wherein the outer surface comprises a top surface of the tray table, and wherein each cell of the plurality of cells of the honeycomb core comprises a central axis extending perpendicular to a plane of the top surface of the tray table.

6 . The tray table of claim 1 , wherein a width of the top sheet is different from a width of the bottom sheet.

7 . The tray table of claim 6 , wherein the width of the top sheet is greater than the width of the bottom sheet.

8 . The tray table of claim 1 , wherein a width of the top sheet is different from a width of the honeycomb core.

9 . The tray table of claim 8 , wherein the width of the top sheet is greater than the width of the honeycomb core.

10 . The tray table of claim 1 , wherein the top sheet comprises a top surface and wherein the bottom sheet comprises a bottom surface, and wherein a surface area of the top surface is greater than a surface are of the bottom surface.

11 . The tray table of claim 1 , further comprising a slide housing within the shroud and attached to the core assembly, wherein the slide housing is configured to engage a sliding mechanism of the tray table, wherein the slide housing is attached to the top sheet, the honeycomb core, or the bottom sheet.

12 . The tray table of claim 11 , wherein the top sheet comprises a top surface and a bottom surface, and wherein the slide housing is attached to the bottom surface of the top sheet.

13 . The tray table of claim 1 , further comprising a slide housing attached to the shroud, wherein the slide housing is configured to engage a sliding mechanism of the tray table.

14 . A passenger seat assembly comprising:
the tray table of claim 1 ; and a table support attaching the tray table to the passenger seat, wherein the tray table is pivotably supported on the table support.

15 . The passenger seat of claim 14 , further comprising a sliding mechanism connecting the tray table with the table support, wherein the tray table further comprises a slide housing within the shroud and attached to at least one of the top sheet or the honeycomb core.

16 . A tray table for a passenger seat, the tray table comprising:
a shroud forming a top surface and a bottom surface of the tray table; and a core assembly within the shroud, the core assembly comprising a honeycomb core defining a plurality of cells, wherein each cell of the plurality of cells comprises a central axis extending perpendicular to at least one of the top surface or the bottom surface of the tray table.

17 . The tray table of claim 16 , wherein the core assembly further comprises a top sheet and a bottom sheet within the shroud, and wherein the honeycomb core is between the top sheet and the bottom sheet.

18 . The tray table of claim 17 , wherein at least one characteristic of the top sheet is different from the bottom sheet, and wherein the at least one characteristic comprises a thickness, a width, or a surface area.

19 . A tray table for a passenger seat, the tray table comprising:
a shroud assembly defining a top surface of the tray table, a bottom surface of the tray table, and a receiving area of the shroud assembly between the top surface and the bottom surface; and a core assembly within the receiving area of the shroud assembly, the core assembly comprising:
a sheet; and
a honeycomb core extending from the sheet and such that the sheet is between the honeycomb core and a portion of the shroud assembly, wherein the honeycomb core defines a plurality of cells.

20 . The tray table of claim 19 , wherein the sheet is a top sheet, wherein the core assembly further comprises a bottom sheet, wherein the honeycomb core is between the top sheet and the bottom sheet, and wherein the shroud assembly comprises a plastic material and the core assembly comprises a metal material.
