ABSTRACT:
A passive three-point lap and shoulder belt system has lap and shoulder belt retractors mounted on the lower rear corner of the door. The shoulder belt is slidable through an anchor loop mounted on the upper rear corner of the door. The inboard ends of the lap and shoulder belts are joined together at the juncture which is connected to a control belt mounted inboard the seat by an inboard retractor. The winding effort of the shoulder belt retractor is greater than the winding effort of both the lap belt retractor and the inboard retractor to locate the juncture of the lap and shoulder belts adjacent the anchor loop so that the lap belt is stowed vertically along the door and the control belt extends diagonally between the inboard retractor and the juncture of the lap and shoulder belts. The inboard retractor has a motor and a latch mechanism which forcibly retract and hold the control belt against the effort of the shoulder belt retractor when the door is closed to position the lap and shoulder belt juncture at the inboard retractor and thereby establish the shoulder belt and lap belt in their restraining positions. When the door is opened the latch mechanism unlocks the control belt for extension by the greater retracting effort of the shoulder belt retractor so that the juncture of the lap and shoulder belts is returned to the door mounted shoulder height anchor loop to lift the lap belt off the occupant.
