机动车辆中使用的轮椅固定和乘员束缚系统

[中文适用范围]： 本 SAE 推荐做法适用于由轮椅束缚系统或装置以及约束轮椅使用者的系统或装置组成的 WTORS。它规定了 WTORS 的设计要求、测试方法和性能要求、制造商对安装人员和用户的说明要求以及产品标记和标签要求。本文件特别强调 WTORS 在 48 公里/小时、20 克正面碰撞中动态性能的设计要求、测试程序和性能要求。它还规定了带式轮椅系紧装置调节装置上织带滑动的测试程序和性能要求，以及轮椅系紧装置部分但无效的接合，以及可被认为有效接合的系紧部件的测试程序和性能要求。附录 F 包括针对 WTORS 的其他建议，这些建议将增强 WTORS 的设计、性能、安装和使用，但目前不需要遵守本文件。本文件的内容适用于面向前坐轮椅的儿童和成人使用的 WTORS，并适用于个人许可机动车辆的乘客和驾驶员以及公共和学校交通中使用的机动车辆的乘客。虽然本文件的大部分重点是使用四点轮椅束缚系统的 WTORS，但除非另有说明，否则本文件的规定适用于所有类型的 WTORS，包括使用对接式轮椅束缚系统的 WTORS。虽然本文件的主要重点是由制造商包装为完整系统或套件的 WTORS，但人们认识到 WTORS 市场的很大一部分由单独的 WTORS 组件和子组件组成，例如出售给的锚固轨道公共汽车制造商，或出售给交通提供商的固定和约束组件。此类 WTORS 组件和组件的制造商可以证明其设备符合本文件，前提是：旨在一起使用以创建 WTORS 的子组件和组件满足本文件的所有适当要求，并且 b．单独销售的组件和组件均附有符合 5.5 的说明，其中“兼容”一词是指一起测试以符合本文件的要求。 [外文原描述]： This SAE Recommended Practice applies to WTORS comprised of a system or device for wheelchair tiedown and a system or device for restraining the wheelchair-seated occupant. It specifies design requirements, test methods, and performance requirements for WTORS, requirements for manufacturer’s instructions to installers and users, and requirements for product marking and labeling. This document places particular emphasis on design requirements, test procedures, and performance requirements for the dynamic performance of WTORS in a 48-km/h, 20-g frontal impact. It also specifies test procedures and performance requirements for webbing slippage at adjustment devices of strap-type wheelchair tiedowns, and for partial but ineffective engagement of wheelchair tiedowns, and tiedown components that could be perceived to be effectively engaged. Appendix F includes additional recommendations for WTORS that will enhance the design, performance, installation, and use of WTORS, but which are not, at this time, required for compliance with this document.The contents of this document apply to WTORS used with forward-facing wheelchair-seated children and adults, and apply to passengers and drivers of personally licensed motor vehicles as well as to passengers of motor vehicles used in public and school transportation. While much of the focus of this document is on WTORS that use four-point wheelchair tiedown systems, unless otherwise specified, the provisions of this document are applicable to all types of WTORS, including those that use docking-type wheelchair tiedowns.While the primary focus of this document is a WTORS that is packaged by the manufacturer as a complete system or kit, it is recognized that a significant portion of the WTORS market consists of separate WTORS components and subassemblies, such as anchorage track that is sold to the bus manufacturer, or securement and restraint assemblies that are sold to the transit provider. Manufacturers of such WTORS components and subassemblies may certify their equipment as being in compliance with this document provided that:aThe subassemblies and components intended to be used together to create a WTORS meet all the appropriate requirements of this document, andbThe separately sold components and subassemblies are provided with instructions in accordance with 5.5 , where the word “compatible” means tested together to comply with this document.Cross Reference: AS2942,CAN-D409-M85,CSAZ604,CSAZ605,DIN75,FMVSS201,FMVSS209,FMVSS222,FMVSS302,ISO10542-1,ISO10542-2,ISO7176/19,ISO7193,J128,J1834_201401,J2094,J211-2,J211/2_201406,J2252,J383_201410,J850_201504,PL-101-476,PL101-336
