Quick release mounting for seat back tray table
First Claim
1. A seat back mounted tray table asembly for a transport vehicle passenger seat which may be quickly assembled not disassembled, without tools, from a mounted relationship with a pair of seat frame members located adjacent the opposed side edges of a seat back member by authorized persons but protected form removal by passengers, said tray table assembly including a tray table and having a pair of spaced, downwardly extending legs pivoted thereto, said legs being joined by a torsion tube but deflectable by authorized persons toward each other at their lower ends;
- a pair of short, axially aligned pivot studs mounted to said seat frame members, said pair of pivot studs forming a pivot axis for said pair of legs and cooperating with a pivot aperture or opening formed in each of said legs to mount said legs;
stop means on said seat frame members for limiting the outward pivotal movement of said legs away from said seat back when said tray table is deployed from its generally vertical storage position in the seat back to a generally horizontal use position; and
means mounted to at least one of said seat frame and seat back members for preventing unauthorized disassembly of said legs from said pair of pivot studs.

Abstract
Improved constructions for mounting seat back tray tables to the frames of vehicle seats permit the tables to be quickly removed and replaced by authorized persons without the use of tools. Small studs on each side of the seat pivotally support apertures in the lower ends of the tray table legs. The legs may be deflected toward each other to release their mounting engagement with the studs but means are provided to prevent such release by unauthorized persons. In one embodiment, release can only be accomplished when the seat back is in its forward "break-over" position. In such position, the legs can be lifted so that a frame-mounted stud having a cylindrical end interrupted by a pair of opposed flats will pass from a small opening in the leg through a slot narrower than the small opening to a larger opening. In a second embodiment, a torsion tube joining the leg ends has a spring-loaded pin and slot connection to one leg so that the leg can be slightly axially retracted along the tube to accomplish release. The dress cover of the seat back includes a rear portion which overlies and conceals the torsion tube.
