Impact Tests of HBU-X Automatic Lap Belt Prototypes.

Abstract

Impact tests were conducted to evaluate three preproduction HBU-X automatic lap belts of different designs developed by three competing contractors. Eight impact tests were performed as part of a program to select a lap belt to replace all HBU and MA-5/6 series lap belts currently in service. Each lap belt was to be tested at progressively higher G levels (32 G, 38 G, and 40 G) and velocities (up to 106 ft/sec) until failure occurred or until the 40 G test level was achieved without failure. Each of the lap belts failed structurally or exceeded the belt adjuster slippage limit (1/2 in.) during the impact tests. Further tests of a single buckle that did not structurally fail in the test series and adjusters that passed the slippage criteria are recommended. (Author)
