The invention relates to an anti-extrusion double-layer guide rail automobile seat applied to the technical field of automobile seats, by arranging double-layer guide rails, when a center console displaces, an ejector can push a seat body and an upper-layer guide rail to the direction away from the center console along a lower-layer guide rail together, and then the distance between the seat body and the center console is increased; compared with the prior art, the situation that a driver is squeezed when the center console moves is effectively avoided, then the rescue difficulty is reduced, and the probability that the driver is rescued when a serious traffic accident occurs is improved; besides, in cooperation with the arrangement of the self-adaptive force relief unit, when the seat body is close to the stroke limit position of the lower-layer guide rail, the buffer bag can conduct self-adaptive pressure relief according to the moving speed of the buffer bag, meanwhile, when the buffer bag reaches the limit position, the upper-layer guide rail and the lower-layer guide rail are controlled to be locked again, and then the position of the seat body is effectively limited; therefore, the device is not easy to move towards the center console again due to the reverse acting force, and the safety is further improved.

    本发明涉及应用于汽车座椅技术领域的一种防挤压的双层导轨汽车座椅,通过设置双层的导轨,当中控台发生位移时,弹射器可将座椅本体和上层导轨沿着下层导轨一同推移至远离中控台的方向,进而拉开座椅本体与中控台之间的距离,相较于现有技术,有效避免在中控台发生移动时驾驶员被挤压的情况发生,进而降低救援难度,提高在出现严重交通事故时,驾驶员的被救概率;另外,配合自适应泄力单元的设置,当座椅本体靠近下层导轨行程极限处时,缓冲囊可根据其移动速度自适应泄压,同时可在到达极限位置时,控制上层导轨和下层导轨再次锁定,进而有效限制座椅本体的位置,使其不易因反向作用力而再次朝向中控台移动,进而进一步提高安全性。
