一种汽车座椅头枕调节机构
本技术涉及汽车座椅配件领域,尤其是涉及一种汽车座椅头枕调节机构。
技术介绍
现有的头枕前后调节方式主要有两种:一种是通过头枕杆顶部直端的轴心旋转,无极调节或棘轮式有级前后旋转调节。缺点是随着头枕调节角度的变化,改变了头枕与乘员头部的接触部位的高度和接触面积,和头枕对头部支撑力的方向和角度,在车辆后撞的鞭挞中将会使人体头部在与头枕撞击使产生不利于颈椎的发作用力,从而使人体颈椎受到较大的外力损伤。第二种是平行四边形四连杆装置实现头枕的前后平移,缺点是使用棘轮装置实现有级调节,零部件较多,结构复杂;且,其只能实现从后向前的单方向调节,操作体验不人性化。因此,实有必要设计一种汽车座椅头枕调节机构,以克服上述问题。
技术实现思路
为解决上述问题,本技术提供了一种设计紧凑,强度更高,能够无级调节头枕的前后位置,从而对使用者达到较好的头部的支撑,同时有向前和向后的限位装置,防止头枕调节范围过度,另一方面,也降低在车辆后撞时的头部鞭挞损伤;同时,也将使得驾乘者在车内休息时通过调节头枕前后位置使头颈得到更加舒适的承托和支撑的汽车座椅头枕调节机构。本技术提供的一种汽车座椅头枕调节机构,包括:头枕杆、壳体、安装座、左安装板、右安装板、前传动板、后传动板、弹簧片;所述弹簧片下端活动套设在所述头枕杆上端;所述安装座固定在所述头枕杆上端,且所述安装座活动安装在所述弹簧片上;所述前传动板下端铰接在所述安装座前端,所述后传动板下端固定在所述弹簧片上;所述左安装板和所述右安装板左右相对设置,所述左安装板和所述右安装板两个安装板上端通过前轴销和后轴销两个轴销连接;所述前传动 ...
