Vehicle seat track assembly

Abstract

An actuating device has an arm which controls the movement of a track locking mechanism for use in conjunction with a vehicle seat assembly adapted for installation in a vehicle. The seat assembly has a first track member, fixed to the vehicle, and a second track member, secured to the vehicle seat, which track members can be locked in position with respect to one another. A cable is attached to a vehicle seatback, and when the seatback is moved from an upright position to a forwardly folded position, the cable moves the arm of the actuating device from a rest position to a cocked position. When the vehicle seat is moved forward to allow access to the rear seat area of the vehicle, the arm of the actuating device correspondingly moves a cam follower from a raised position to a lowered position. The cam follower restrainingly engages the arm in the cocked position against the biasing of a spring member. When the seat is returned to an occupancy position and the seatback to its upright position, the cam follower contacts a cam that is located at a set position. Upon such contact, the cam follower is moved from its lowered position to its raised position, thus releasing the arm to its rest position. The track locking mechanism is correspondingly allowed to return to its locking configuration, thus locking the vehicle seat in place at this set position.
