Abstract
The track assembly of a seat adjuster is formed by upper and lower tracks of inverted U-shaped cross-section with the lower track being nested in the upper track and with the rear end portion of the upper track serving as an anchor for a seat belt. A tubular sheath of anti-friction material is located between the tracks to promote gliding of the upper track on the lower track. Crash bars with longitudinally spaced teeth on their lower edges are housed within and anchored to the lower track. If the vehicle is involved in a frontal crash, load exerted by the seat belt on the upper track causes the rear end portion of the upper track to buckle upwardly and bring a latch on the lower side of the upper track into latching relation with the teeth of the crash bars for purposes of locking the upper track against upward and forward movement relative to the lower track. The bottom of the sheath normally holds the latch out of latching relation with the teeth and yields under a crash condition to allow the latch to move into latching relation with the teeth.
