ABSTRACT:
A vehicle seat is mounted on the vehicle floor by a seat adjusting mechanism permitting fore and aft adjusting movement of the seat. A grooved rod is mounted on the vehicle floor. A locking device connected to the seat belt buckle houses a jaw sleeve which surrounds and is normally freely slidable along the grooved rod during seat adjustment. The jaw sleeve is slotted at one end to form a plurality of tooth members having a ramped outer surface. A collar formed integral with the jaw sleeve is threaded to receive a bolt attach to the seat adjuster and provides the connection of the locking device with the seat adjuster. The collar is moveable within a recess in the housing of the locking device from the normal, unlocked position in which the tooth members clear the grooves of the rod to a locked position in which the housing acts on the ramped surface of the tooth members to deflect the tooth member into a rod groove to lock the locking device on the rod under the imposition of a substantial occupant restraint load on the locking device by the seat belt. The seat belt attachment bracket is pivotable about the locking device housing to allow variable positioning of the belt buckle assembly during seat adjustment.
