The invention provides a seat collision retraction structure, a seat assembly and an automobile, the seat collision retraction structure comprises an upper slide rail, a lower slide rail is arranged below the upper slide rail, an upper front end fixing plate is arranged at the front end of the upper slide rail, and a lower front end fixing plate is arranged at the front end of the lower slide rail; the two ends of the blasting screw are installed between the upper front end fixing plate and the lower front end fixing plate correspondingly, and the upper sliding rail is fixed to the lower sliding rail. The compression spring is sleeved on the blasting screw and is sealed between the upper front end fixing plate and the lower front end fixing plate, and the compression spring is in a compressed state; when the vehicle collides forwards, the explosion screw is exploded and fractured after receiving a signal, the compression spring extends and resets under the action of spring force, and the upper sliding rail is pushed to drive the vehicle seat connected to the upper portion to move backwards along the lower sliding rail to leave the front space of the vehicle seat. Human bodies are prevented from being hurt by colliding with front parts, and the safety of passengers is improved.

    本发明提供一种座椅碰撞退缩结构、座椅总成及汽车,包括上部滑轨,所述上部滑轨的下方设置有下部滑轨,所述上部滑轨前端设置有上前端固定板,所述下部滑轨前端设置有下前端固定板,所述爆破螺丝的两端分别安装在上前端固定板和下前端固定板之间,将上部滑轨固定在下部滑轨上;所述压缩弹簧套在爆破螺丝上并封闭在上前端固定板和下前端固定板之内,且压缩弹簧处于压缩状态;爆破螺丝接收信号爆破断裂,压缩弹簧在弹簧力作用下伸长复位,推动上部滑轨带动上方连接的车座椅沿下部滑轨向后移动,让出车座椅前部空间,本发明申请车辆发生前碰时实现座椅及人体的快速向后调节,防止人体撞向前面部件而受伤,提升乘员安全性。
