Abstract

A seat leg and track fitting assembly for removably securing a seat to a generally channel-shaped track secured to the fuselage of an aircraft. The track fitting assembly includes a forged body member having a narrow finger portion; a plurality of spaced track lugs projecting laterally from the narrow finger portion, and an enlarged boss portion having a recess formed therein. The recess extends through the narrow finger portion to form a pair of shoulders adjacent opposite sides of the recess and a plunger has surfaces positioned between the shoulders such that the shoulders limit movement of the plunger. An actuating arm is secured to the plungers in each of a plurality of track fitting assemblies to move the plungers in the recesses between first positions wherein the lower ends of the plungers are positioned adjacent the lower edge of the narrow finger portion of each body and an elevated position wherein the plungers are retracted from the track.
