Abstract:

Impact tests were performed to evaluate the adequacy of 1-34-in webbing adjusters proposed for the HBU-12 automatic lap belt. Four tests were conducted at impact levels ranging from 41.8 to 43.7 with impact velocities ranging from 84.9 to 86.7 ftsec. The tests were accomplished using the Air Force Medical Research Labs Horizontal Decelerator Facility with anthropometric dummy subjects. The adjusters were installed on the HBU-12 lap belt and tested with an MB-6 double shoulder harness. During the first impact test, the metal clevis of the shoulder harness failed at its attachment point but the lap belt and adjusters successfully withstood the impact loads. The subsequent three tests were completely successful. Originator-supplied keywords include Restraint, Adjusters and Impact protection.
