Crash performance of emergency locking retractor seat belts : TARU 5/76

The crash performance of emergency locking retractor (inertia reel) seat belts is examined by in-depth field investigations and by laboratory simulations. It is found that the inclusion of the retractor increases body excursions for the wearer of a lap/sash seat belt. The increase is not excessive and in general, crash performance is found to be satisfactory. The Australian Design Rule requirements for emergency locking retractor seat belts are examined and a number of efficiencies are discussed. It is concluded that a revised dynamic test is required, based on the limitation of excursions of a specific validated anthropomorphic dummy.

本研究通过深入的现场调研与实验室模拟试验，对紧急锁止式卷收器安全带 (emergency locking retractor (inertia reel) seat belts) 的碰撞性能展开评估。研究发现，加装该卷收器会使胯肩组合式安全带佩戴者的身体位移量有所增加。该增幅并未超出合理范围，整体而言其碰撞性能表现令人满意。本研究同时对紧急锁止式卷收器安全带的澳大利亚设计规则（Australian Design Rule，ADR）要求进行了评估，并就多项效能指标展开了讨论。最终得出结论：需基于特定经过验证的拟人测试假人的位移限值，修订现有的动态试验方案。
