  • Patent number: 4047689
    Abstract: Track fitting for anchoring seats or cargo to a slotted floor track in an aircraft includes a plurality of spaced lobe portions which are adapted to be positioned so as to underlie retaining portions of the track to restrict upward movement of the fitting. Forward movement is restricted by shear pin means positioned so as to engage the track intermediate a pair of lobe portions. In a preferred embodiment, the fitting has four sets of lobes and two shear pins. The lobes are located in alternate pairs on first and second pivoted support plate means which are sandwiched together inside a housing and pivotally mounted fore and aft of the load attachment aperture in the housing so that the lobes and support plates can pivot under load to uniformly distribute the loading over an extended track length.
