轮椅座椅第13部分:座垫横向稳定性的测定

[中文适用范围]： 本文件规定了通过测量坐垫对坐垫上负载质心移动的响应来确定轮椅座垫横向稳定性能的设备、测试方法和披露要求。 它提供了一种确定坐垫特定物理和机械性能变化的方法。 它不提供特定于特定个人用户的缓冲性能的信息。 它不提供与前后稳定性相关的信息，也不提供与坐垫边缘的稳定性贡献相关的信息。 注 1：测试条件模拟对称解剖结构。 注 2：负载旨在代表 40% 至 60% 轮椅使用者骨盆下方的负载。 本文件适用于轮椅以外情况下使用的垫子。 [外文原描述]： This document specifies apparatus, test methods, and disclosure requirements for determination of lateral stability properties of wheelchair seat cushions by measuring the response from the cushion to a shift in the centre of mass of the load on the cushion. It provides a method of determining changes in a particular physical and mechanical property of the cushion. It does not provide information specific to cushion performance for a particular individual user. It does not provide information related to anterior-posterior stability, nor to stability contributions from cushion edges. NOTE 1 Test conditions simulate a symmetric anatomy. NOTE 2 Loads are intended to represent those seen under the pelvis of a 40th to 60th percentile wheelchair user. This document is applicable to cushions used in situations other than a wheelchair.
