Seat belt anchor for vehicle seat

摘要

A seat adjuster has upper and lower tracks slidably inter-engaged with the seat carried by the upper track. A bar extends along side the upper track and has a rearward end pivotally mounted on the vehicle floor. A lock member which carries the seat belt is attached to the upper track and slides freely along the bar during normal fore and aft adjusting movement of the seat. The lower track is mounted on the vehicle floor by yieldable legs. Upon rapid vehicle deceleration, the forward momentum of the seat mass induces yielding of the yieldable legs and forward canting of the seat causing the lock member to be canted relative the bar and lock therewith so that the occupant restraint loads imposed on the seat belt are transmitted through the lock member and bar to the vehicle floor. In addition, when the seat is adjusted full rearwardly, the upper track is cantilevered rearwardly from the lower track so that the upper track yields and bends to further cant the lock member and contribute to the locking engagement of the lock member with the bar.
