礼堂椅如何保护腰椎？
发布日期：2019-10-15 23:09:44
礼堂椅的设计要说简单也不简单，要说复杂也不复杂，结构包括扶手、脚架、座包和靠背，有时候扶手会和脚架连在一起，做成扶脚的样式，剩下的座包和靠背。不少人以为礼堂椅保护人体腰椎最重要靠的是靠背。
其实不然，礼堂椅保护人体的腰椎关乎到礼堂椅的整体结构。首先是扶脚一定要稳固，如果扶脚不够牢靠，不小心就会动，人体腰椎可能会受到突如其来的变化而受伤，所以礼堂椅的扶脚都做得十分坚固，长时间摆放也不会出现变形等情况。
其次就是座包，座包主要接触的是人体的臀部，支撑人体重心，不要以为看起来跟腰椎没什么关系哦！如果座包不稳或者变形，导致人体重心不停变化或者停在不恰当的地方，就会影响腰椎，因为重心不稳，腰椎需要以一个不太舒服的姿势来保持身体平衡。
最后就是靠背了，靠背的设计十分重要，因为它是与腰椎直接接触的，对于腰椎的支撑是最为重要，所以靠背一般都要根据人体工程学来设计，保证侧面曲线能紧贴腰椎的曲线，给人体腰椎最好的支撑点，防止腰椎的支撑力不足造成腰椎劳损。
