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 comprising a top wall, a bottom wall, and a side wall extending between the top wall and the bottom wall, wherein the top wall, bottom wall, and side wall form an outer surface of the tray table, and wherein the top wall, bottom wall, side wall define a receiving area of the shroud; and
a core assembly within the receiving area of the shroud and such that the core assembly is enclosed within the shroud, the core assembly comprising:
a top sheet;
a bottom sheet;
a honeycomb core between the top sheet and the bottom sheet, wherein the honeycomb core defines a plurality of cells; and
a slide housing positioned within the shroud and secured to the core assembly at the top sheet or the honeycomb core, wherein the slide housing is configured to engage a sliding mechanism of the tray table.

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 enclosed 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;
a top sheet;
a bottom sheet, wherein the honeycomb core is between the top sheet and the bottom sheet; and
a slide housing positioned within the shroud and secured to the core assembly at the top sheet or the honeycomb core, wherein the slide housing is configured to engage a sliding mechanism of the tray table.

17. The tray table of claim 16 , 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.

18. 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 enclosed within the receiving area of the shroud assembly, the core assembly comprising:
a top sheet;
a bottom sheet; and
an 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, wherein the honeycomb core is positioned between the top sheet and the bottom sheet; and

a slide housing positioned within the shroud and secured to the core assembly at the top sheet or the honeycomb core, wherein the slide housing is configured to engage a sliding mechanism of the tray table.

19. The tray table of claim 18 , wherein the honeycomb core comprises aluminum, and wherein the shroud assembly comprises a plastic material.
