ABSTRACT:
Disclosed is a leg seat track fitting used to removably secure the leg of an airplane seat to the floor of the fuselage. The fitting has a body member, including a wall element from which a series of pairs of tabs project outwardly. These tabs engage the track in which the fitting is carried. A pivotable detent element attached to one end of the wall element secures the fitting in position when depressed. A yoke element mounted at another end of the wall is moved towards and away from the body member by a spring loaded screw. This yoke includes a pair of plungers which straddle the wall and engage the floor of the track when the yoke is moved toward the body member. The detent element and plungers resist sliding movement of the fitting in its track. To absorb energy when torque is exerted on the seat, a spherical bearing fitting snugly in its race carries a pin which passes through this bearing member and attaches to the leg of the seat.
