"QUICK RELEASE MOUNTING FOR SEAT BACK TRAY TABLE" 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 inter- rupted 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.
