坐垫要如何选择

1、轮椅的座面深度：所谓座面深度是指座面前后的距离。这个距离的长度应该允许用户的整个臀部得到有效的支撑。另外，合理的座深不宜过长，允许使用轮椅。靠背方便地支撑用户的腰椎。这个距离大约是用户整个大腿长度的四分之三。座垫表面的形状要与使用者臀部的曲线相适应，使凹凸相得益彰，并具有一定的弹性和支撑性。

2、轮椅的座面宽度：座面宽度是指轮椅座面左右两侧的横向距离。座面宽度的距离首先要满足使用者臀部的水平宽度。人体尺寸中臀部的宽度决定了座垫宽度的最小距离。

3、轮椅的臀部坐深：指人坐在座垫上时臀部底部最低点到座垫平面的垂直距离。我们可以通过实验模拟得到一个更合适的臀座深度约30mm。由于臀部对座垫的压力向外逐渐减小，因此座垫的最深度在其他方向上应该是合理的弧形设计，这样会对腿部保持一定的支撑，减轻腿部的负担。
