Abstract

A seat track assembly comprises a lower track assembly having a lower track and an upper track assembly slidable over the lower track assembly and having an upper track. An elongate upper bracket and an elongate lower bracket enhance resistance to vertical dislocation. The upper bracket is attached to the upper track and has first and second projections which are positioned on opposite sides of the upper track. The lower bracket is attached to the lower track. The upper bracket can slide free of the lower bracket in a normal operating condition, and the first and second projections of the upper bracket are received by the lower bracket to resist vertical dislocation of the upper track when the upper track assembly is subjected to a vertical dislocation force. The first and second projections are preferably unitary extensions of the upper bracket, and are connected to each other by a connecting segment attached to the upper track. Preferably the upper bracket first and second projections are mirror images of one another so that a vertical dislocation force transmits loading evenly across the brackets. A pair of upper track assemblies can be used with a pair of lower track assemblies, each upper track having an upper bracket as described and each lower track having a corresponding lower bracket.
