ABSTRACT:
A quick disconnect assembly (20) provides for the releasable attachment of a fixture, such as a helicopter seat frame (26), to a support structure, such as the interior structure of the aircraft cabin (28). The assembly includes a tie down stud (100) having a substantially spherical outer surface (182) and a threaded bolt (188) extending therefrom for attachment to the support structure. An attachment fitting (22) is provided having a main body (40) with means for attachment (56) to the fixture. A plurality of grip arms (148) are pivotally associated with the main body. The arms have inwardly curved ends (156) for cooperating with the spherical outer surface of the stud to engage the stud by positioning the arms inwardly. With the attachment fittings secured to the tie down stud, the attachment fitting is movable relative to the stud through a predetermined angle.
