The invention discloses a zero-gravity seat crumple mechanism which comprises a base and a seat frame located on the upper side of the base, the rear end of the seat frame is rotationally connected with the base, the front end of the seat frame is rotationally connected with an upper linkage component, the front end of the base is rotationally connected with a lower linkage component, and the upper linkage component and the lower linkage component are hinged to each other through a pin shaft. The crumpling device is characterized in that one side of the upper linkage part is fixedly connected with a crumpling piece, the crumpling piece is provided with a transfer hole located in the lower portion, a crumpling channel located in the upper portion and a weakening portion formed between the transfer hole and the crumpling channel, the upper linkage part is provided with a strip-shaped receding hole, and the transfer hole and the crumpling channel are both exposed in the strip-shaped receding hole. The method has the beneficial effects that when the automobile is collided, the seat can instantly return to the normal sitting posture mode from the zero-gravity mode, and the safety of the seat is improved.

    本发明公开了一种零重力座椅溃缩机构,包括底座以及位于底座上侧的座框,座框后端与底座转动连接,座框前端转动连接有上联动部件,底座前端转动连接有下联动部件,上联动部件与下联动部件通过销轴互相铰接,其特征在于:所述上联动部件一侧固接有溃缩片,溃缩片具有位于下部的转接孔、位于上部的溃缩通道、以及成型在转接孔和溃缩通道之间的弱化部,所述上联动部件具有条形避让孔,转接孔和溃缩通道均暴露在条形避让孔内。本发明的有益效果是:汽车发生碰撞时,座椅能够瞬间从零重力模式回到正常坐姿模式,提升座椅安全性。
