Automotive seats are tested for compliance with federal motor vehicle safety standards (FMVSS) to assure safety during impact. Many wheelchair users rely upon their wheelchairs to serve as vehicle seats. However, the crashworthiness of these wheelchairs during impact is often unknown. This study evaluated the crashworthiness of five combinations of wheelchair back support surfaces and attachment hardware using a static test procedure simulating crash loading conditions. The crashworthiness was tested by applying a simulated rearward load to each seat-back system. The magnitude of the applied load was established through computer simulation and biodynamic calculations. None of the five tested wheelchair back supports withstood the simulated crash loads. All failures were associated with attachment hardware.
汽车座椅需经过测试以确保符合联邦机动车安全标准（FMVSS），从而保证在碰撞时的安全性。许多轮椅使用者依靠他们的轮椅作为车辆座椅。然而，这些轮椅在碰撞时的耐撞性往往未知。本研究使用模拟碰撞加载条件的静态测试程序，评估了五种轮椅靠背支撑表面和固定硬件组合的耐撞性。通过对每个座椅靠背系统施加模拟向后载荷来测试耐撞性。施加的载荷大小通过计算机模拟和生物动力学计算确定。测试的五种轮椅靠背均无法承受模拟碰撞载荷。所有故障均与固定硬件有关。
