ABSTRACT:
A load limiting apparatus for a vehicle safety restraint belt is inserted in the force path between a mounting for a seat belt and a vehicle occupant. The load limiting apparatus has a vessel which contains fluid. The fluid is moved from one part of the vessel to another through a valve having a tapering profile to decrease the open area of a constriction as a function of the deceleration of the vehicle in a crash. Ideally the load limiting is self regulating and the force absorbed increases with increasing crash severity.
