Seat belt anchoring apparatus.

摘要

Apparatus for securing a seat belt to a longitudinally adjustable seat track mechanism (12) of a motor vehicle. The seat belt is connected to one end of a lever (60, 60'), the lever being pivotal within the legs of a stepped U bracket (40), the step being secured to the movable track (16) of the mechanism (12). The lever (60, 60') has a clamp end normally held out of engagement with a longitudinally extending tension member such as a wire cable (70) secured to the vehicle body (23). The lever is held in its normal condition by either a shear pin (94) or by the action of a helical spring (80). When a crash load is applied to the seat belt, the load causes the pin (94) to shear (or when a spring is used - overcomes the spring bias) and the lever (60, 60') freed of restraint rotates to a position clamping the tension member I (70) against the base of the U bracket (40) and preventing movement of the seat and seat belt relative to the vehicle body.
