The invention discloses a vehicle seat buffer structure, when a vehicle is collided and a vehicle seat is subjected to external force, a mounting bolt for connecting a seat guide rail displaces, a bolt hole deforms at a weakening groove, and when the bolt hole deforms to a certain amount, a connecting part between the bolt hole and the weakening groove is cut off by the mounting bolt; meanwhile, the sensing part sends out an unlocking command, so that the gas spring is decompressed and unlocked, the mounting bolt is in contact with the sliding block, and the metal spring is compressed, when the collision force is small, buffering can be performed through the shearing effect of the connecting part between the bolt hole and the weakening groove and the elasticity of the metal spring, and when the collision force is large, the mounting bolt enters the longitudinal part of the T-shaped hole while compressing the metal spring, and due to the fact that the width of the longitudinal part is smaller than the diameter of the mounting bolt, the mounting bolt can shear the crumple part to further buffer and absorb energy.

    本发明公开了一种车辆座椅缓冲结构,在车辆受到碰撞,车辆座椅受到外力时,用于连接座椅导轨安装螺栓将发生位移,螺栓孔将在弱化槽处发生形变,形变至一定量时,螺栓孔与弱化槽之间的连接部将被安装螺栓剪断,与此同时感测部发出解锁命令,使气弹簧泄压解锁,安装螺栓与滑块进行接触,并压缩金属弹簧,当碰撞力较小时,通过螺栓孔与弱化槽之间的连接部的剪切作用以及金属弹簧的弹性即可进行缓冲,当碰撞力较大时,安装螺栓在压缩金属弹簧的同时将进入T形孔的纵向部分,由于纵向部分的宽度小于安装螺栓直径,安装螺栓将会对溃缩部进行剪切,进一步缓冲吸能。
