Each of a pair of primary pawls is configured to be driven into an engaged position by a primary camming surface of the primary cam and a camming edge, and into a disengaged position by a camming edge of the secondary cam. Each of a pair of secondary pawls is configured to be driven into an engaged position by a secondary camming surface of the primary cam and into a disengaged position by a camming edge of the secondary cam.

Abstract: A track assembly of a vehicle seat adjuster includes an upper track secured to the seat and adjustable back and forth along a lower track which is anchored to the vehicle floor pan. Friction between the tracks is reduced by load-bearing rollers located between the tracks at the center thereof and by spherical balls located between the tracks along the sides thereof. The rollers travel independently of the balls to prevent possible binding of the rollers, the balls along each side of the track being held in fixed longitudinally spaced relation by a strip-like retainer.
