与耳朵齐平!
头枕高度合适才能更好起到保护效果
否则可能会适得其反
增加伤害性
许多车主喜欢将头枕作为颈枕来使用
将头枕降至最低
垫在颈部后方
靠上去觉得很舒服
但是,其实这样的做法非常危险!
过低的头枕垫在颈后,在遇到追尾事故时,巨大的冲击力会通过头枕直接传递给颈部,而头部则因为惯性向后翻转,颈部会遭受非常严重的伤害,甚至可能出现折断颈椎这样的致命伤;如果头枕高于头部很多,在受到撞击时,头部很可能会被向下挤压,头部被压低,造成颈部严重伤害。另外,头部被下压时有可能还会撞到头枕的金属杆,造成更严重的伤害。
一般来说,头枕中央是最为柔软的,在遭遇外力冲击时,头部靠在头枕中央最为安全。所以,调节头枕正确的高度是,将头枕中央与耳朵上沿平行,这样就使头部中间对应头枕中央,在受到冲击时,头枕最柔软的部分会给予头部安全的保护。
今天的三秒知识点就是这样
咱们下期再见咯~
