Development of Load-Limiting Wheelchair Securing System

轮椅和其他轮式移动装置（WMD）在公共汽车上的固定存在安全和人为因素问题。许多轮椅在不寻常的事件期间不能抵抗当前固定系统的负载。此外，许多轮椅没有适当地固定，因为固定是困难的。提出了一种能量吸收和载荷限制捆扎系统的发展，以减少受伤的风险。此外，将开发附件工具，以方便使用。虽然通用附件系统正在开发中，但它们不能很好地与现有的公共汽车或大规模杀伤性武器配合使用。该计划的总体目的是改善报废系统的功能，使现有系统可以在新公交车上轻松实现改造和负载限制。该系统将对今天运输的大规模毁灭性武器有效。设计的可行性将在第一阶段提案中进行评估。将对限载带进行制造和测试，以证明我们有能力可靠地设计限载系统。将开发附接和释放捆扎系统的改进方法。拟议的商业应用：该系统将满足所有FMVSS和ADA要求，并有助于减少残疾人乘坐公共交通工具时可能发生的伤害。这种限载带设计适用于所有车辆的乘员约束带。

Securement of wheelchairs and other wheeled mobility devices (WMDs) on buses presents safety and human factors problems. Many wheelchairs cannot resist the loads of current securing systems during unusual events. Also, many wheelchairs are not secured properly because securement is difficult. Development of an energy-absorbing and load-limiting strapping system is proposed to reduce the risk of injury. Also, attachment tools will be developed to provide easy use. Although universal attachment systems are under development,, they do not work well with existing buses or WMDs. The overall purpose of this program is to improve the functionality of scrapping systems in such a way that current systems can be retrofit and load-limiting easily implemented in new buses. The system will be effective for WMDs transported today. The feasibility of the design will be evaluated in this Phase I proposal. Load-limiting belts will be fabricated and tested to demonstrate our ability to reliably design a load-limiting system. Improved methods of attaching and releasing strapping systems will be developed. PROPOSED COMMERCIAL APPLICATIONS: This system will meet all FMVSS and ADA requirements and help reduce the possible injury of people with disabilities when riding public transportation. This load-limiting belt design is adaptable to occupant restraint belts for all vehicles.
