Abstract

Described are tray table assemblies comprising a table body including a frame. The frame is formed of an upper bar and a lower bar that connect a pair of slide guides, wherein the upper bar, the lower bar, and the pair of slide guides are integrally formed as a single piece.

First claim

That which is claimed is:

1. A tray table assembly comprising:
a pair of slide guides; and
a table body positioned between the slide guides, the table body comprising a frame, the frame comprising an upper bar and a lower bar that connect the pair of slide guides in a substantially parallel alignment;
wherein the upper bar, the lower bar, and the pair of slide guides are manufactured together as a unitary one-piece construction so that the substantially parallel alignment between the pair of slide guides does not vary due to a cumulative effect of part tolerances among individually-assembled components.

2. The tray table assembly of claim 1 , wherein the table body is formed of aluminum, stainless steel, aramid fibers, polycarbonate, or polypropylene.

3. The tray table assembly of claim 1 , wherein the table body has a thickness that is not greater than approximately one-half inch.

4. The tray table assembly of claim 1 , wherein the tray table assembly is configured to substantially fit within a recess formed in a seat back of a passenger seat.

5. The tray table assembly of claim 4 , wherein a first end of each of a pair of retractable arms is coupled to the pair of slide guides, and a second end of each of the pair of retractable arms is pivotally coupled to the seat back.

6. A passenger seat comprising:
(a) a tray table assembly comprising
a pair of slide guides; and
a table body positioned between the slide guides, the table body comprising a frame, the frame comprising an upper bar and a lower bar that connect the pair of slide guides in a substantially parallel alignment,
wherein the upper bar, the lower bar, and the pair of slide guides are manufactured together as a unitary one-piece construction so that the substantially parallel alignment between the pair of slide guides does not vary due to a cumulative effect of part tolerances among individually-assembled components;

(b) a first end of each of a pair of retractable arms is coupled to each of the pair of slide guides; and
(c) a second end of each of the pair of retractable arms is pivotally coupled to a seat back.

7. The tray table assembly of claim 6 , wherein the table body is formed of aluminum, stainless steel, aramid fibers, polycarbonate, or polypropylene.

8. The tray table assembly of claim 6 , wherein the table body has a thickness that is not greater than approximately one-half inch.

9. The tray table assembly of claim 6 , wherein the tray table assembly is configured to substantially fit within a recess formed in the seat back of the passenger seat.

10. A tray table assembly comprising
a pair of slide guides; and
a table body positioned between the slide guides, the table body comprising:
(a) upper bar connecting a first end of each of the pair of slide guides;
(b) a lower bar connecting a second end of each of the pair of slide guides; and
(c) a pair of diagonal supports, each of the pair of diagonal supports connecting the first end of one of the pair of slide guides to the second end of another one of the pair of slide guides;
wherein the pair of slide guides are connected in a substantially parallel alignment;
wherein the upper bar, the lower bar, the pair of slide guides, and the pair of diagonal supports are manufactured together as a unitary one-piece construction so that the substantially parallel alignment between the pair of slide guides does not vary due to a cumulative effect of part tolerances among individually-assembled components.

11. The tray table assembly of claim 10 , wherein the table body is formed of aluminum, stainless steel, aramid fibers, polycarbonate, or polypropylene.

12. The tray table assembly of claim 10 , wherein the table body has a thickness that is not greater than approximately one-half inch.

13. The tray table assembly of claim 10 , wherein the tray table assembly is configured to substantially fit within a recess formed in a seat back of a passenger seat.
