ABSTRACT:
A rollerless seat track assembly and a motor vehicle seat having a rollerless seat track assembly is shown having a lower track mounted to a base or floor of a motor vehicle, and a slidable upper track attached to a seat base. The upper track has a top wall and a pair of side walls. The lower track has a pair of flanges positioned adjacent a primary load bearing contact surface. Preferably a low friction coating, such as a PTFE epoxy paint is applied to the primary load bearing contact surface of the lower track, and a preferably elongate glide strip or glide member may be affixed to a lower side of the top wall of the upper track. As the seat track slides back and forth, the glide strip would slide over the low friction coating, minimizing the efforts required to adjust the seat. Lateral stability may be enhanced by lateral stabilization ball bearings running in raceways between the upper and lower tracks. Preferably a swizel stick or retainer having a series of openings sized to receive the ball bearings is positioned in each raceway to maintain proper spacing of the ball bearings. Optionally the raceway may have four contact points with each ball bearing. The tracks may be interlocking, that is, capable of resisting upward dislocation forces.
