<p>An automatic releasing seat belt assembly utilizes a plate attached to a flexible belt portion of a seat belt. The plate is provided with a rectangular opening. A housing is attached to the other seat belt component having a compartment therein which is accessible by having a slot on one side and an opening on another side adjacent to the side of the slot. The plate is inserted in the slot such that the opening in the plate is disposed adjacent to the opening in the housing. Within the housing there is a camming plate utilizing a spring to bias upwardly and outwardly towards the opening in the housing a camming edge thereof. The camming edge engages one side of the opening in the plate. Thus, when the plate is inserted into the slot, the camming plate locks the plate into a given position. A flexible cable is disposed having one end engaged within the cavity of the housing and has a cam rod attached to the end of the inner cable portion thereof. When the inner cable is retracted, the cam rod is pulled toward the camming edge of the cam plate so as to dispose it downwardly, releasing the cam plate edge from the plate thereby disengaging same. The cam rod is activated by a solenoid coil, which in turn is sensitive to a plurality of sensors disposed about the interior portion of a motor vehicle, such sensors being responsive to an impact. Upon impact, the sensors operate a timer which energizes the solenoid to activate the cam rod and thereby to release the cam plate.</p> |
