ABSTRACT:
A track fastener apparatus for use with a locking track of the type used to secure a seat or cargo apparatus to the floor of a vehicle. The track includes a slot, and the upper walls of the slot have regularly spaced-apart enlarged openings separated by relatively narrower track slot segments defining locking segments. The track fastener apparatus includes a housing. The track fastener housing has a top side and a bottom side with first and second spaced-apart locking studs on the bottom side, the spacing of the locking studs being the same as the spacing of the spaced-apart enlarged openings in the track for being positioned into the enlarged openings. A locking wedge is extended through one enlarged opening in the slot when the locking studs are shifted along the length of the track to adjacent, relatively narrow locking segments, and tightened into the slot to prevent movement of the track fastener apparatus in the track. A screw member cooperates with the track fastener housing and the locking wedge to perform first and second functions in distinct first and second locking wedge positions. In the case of the first position, the locking wedge is not completely positioned in alignment with and into the one enlarged opening, preventing the locking wedge from being tightened into the track. In the case of the second position, the locking wedge is positioned in alignment with and into the enlarged opening, permitting the locking wedge to be tightened into the track.
