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