A vehicle seat adjuster includes a pair of spaced upper tracks, each slidably mounted in one of a pair of lower tracks. A seat support arm connected to each upper track slidably extends through a slot formed in each lower track. A rod extends between each pair of track assemblies and releasably engages a notch formed in each support arm and one of a plurality of notches formed in the lower track to releasably lock the upper track in a stationary position relative to the lower track. A bearing conforming to the shape of the upper track is interposed between each upper and lower track. Support members are connected to each lower track to anchor each lower track to a vehicle floor. Cooperating resisting elements are formed in each upper and lower track pair and inter-engage under deforming load of the tracks and bearing to resist separation of the upper track from the lower track.
