ABSTRACT:
In a dual spool seat belt retractor system where one retractor reels in a shoulder belt and another retractor reels in a lap belt and at least one of the retractors, e.g., the shoulder belt retractor, has an associated tension relieving mechanism which relieves the winding spring tension from the belt worn by the occupant, a device associated with the tension relieving mechanism for releasing the mechanism from its tension relieving mode is actuated by a cable extending between the two retractors. One end of the cable is connected to the release device and the other end is connected to the lap belt retractor in a manner that is senses full lap belt retraction. In a preferred embodiment, the cable is looped partially around the windings of the lap belt retractor so that as the diameter of the lap belt winding increases during lap belt retraction, the cable loop expands causing the other cable end to pull on the release device. The cable actuator is adaptable to a two retractor seat belt system irrespective of the relative orientations of the two retractors. A mechanism is also provided to allow the retractor to be mounted at several angles to the vertical, e.g., 45.degree. and still use the vertical displacement of an inertia member to lock the retractor.
