Abstract
An aircraft seat comprising a pair of pivot pins, a pair of spaced seat back mounting brackets having apertures therein to permit the insertion of the pins therethrough, a pair of side frame forgings, each including a boss, each of the bosses including a peripheral clamping surface and an aperture therein for receiving one of the pins such that the pin and the boss surface have a common axis, a tray assembly including a pair of legs having bifurcated clamp ends for clamping over the peripheral clamping surfaces for selective pivotal motion relative thereto, whereby the tray assembly and the seat back brackets pivot about the common axis, the tray assembly can be removed without removing the seat back mounting brackets, and the seat back mounting brackets may be removed, by removing the pins, without removing the tray assembly.

4. An aircraft seat comprising
a pair of spaced seat back mounting brackets, a tray assembly including a pair of spaced legs, a first support for supporting one of said brackets and one of said legs, a second support for supporting the other end of said brackets and the other one of said legs, said supports each including a post means having first and second selectively separable pieces, each said piece having a peripheral surface concentric to a single predetermined axis, said legs having bifurcated clamp ends for selectively clamping over said first post piece peripheral surfaces for pivotal rotation relative thereto, and said brackets having aperture means therein for receiving said second post pieces therethrough such that said brackets can be mounted on said second post pieces for pivotal rotation about said axis whereby said seat back mounting brackets and legs pivot about the same axis, said tray assembly can be removed from said support means without removing said brackets and vice versa.
