Abstract
Abstract A seat slide structure which includes upper and lower tracks, each formed of a pair of complementary opposite hand track members. The track members of the upper track interfit with the track members of the lower track and are normally interengaged therewith through a plastic spacer between the tracks. Occupancy of a seat supported by the slide structure compresses the spacer to release the upper track for movement relative to the lower track. The upper track is driven relative to the lower track by means of a gear housed between the members thereof and engageable with gear teeth of the spacer. Screwjack mechanisms are housed between the members of the upper track to support a seat thereon for vertical adjustment. The upper track members also support a gear mechanism to adjust the inclination of a seat back supported on the upper track.
