Impact Tests of Adjusters for the HBU-12 Lap Belt.

Abstract

Impact tests were performed to evaluate the adequacy of 1-3/4-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 ft/sec. The tests were accomplished using the Air Force Medical Research Lab's 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.
