摘要：【中文】本发明公开了一种带气囊减震器座椅的限高机构，包括交叉臂，交叉臂包括内臂和外臂，内臂和外臂交叉设置，且内臂和外臂的交叉处通过销轴连接，交叉臂上设置有限制机构，限制机构包括两个连接杆，两个连接杆的一端通过销轴连接，两个连接杆的另一端分别活动连接内臂和外臂，内臂和外臂连接连接杆的连接点位于内臂和外臂交叉点的同一侧，两个连接杆之间连接的一端指向远离内臂和外臂交叉点的一侧，其中一个连接杆上固定连接有阻挡板，交叉臂上设置有凸轮，且凸轮与阻挡板配合，凸轮的回转中心通过销轴安装在交叉臂上，交叉臂上还设置有调节装置，调节装置控制凸轮转动。本技术方案通过阻挡板去接触凸轮，当阻挡板接触凸轮时，从而来限制高度。 【EN】The invention discloses a height limiting mechanism of a seat with an airbag shock absorber, which comprises a cross arm, wherein the cross arm comprises an inner arm and an outer arm which are arranged in a cross way, the crossing part of the inner arm and the outer arm is connected through a pin shaft, a limiting mechanism is arranged on the crossing arm and comprises two connecting rods, one ends of the two connecting rods are connected through the pin shaft, the other ends of the two connecting rods are respectively and movably connected with the inner arm and the outer arm, the connecting point of the connecting rods for connecting the inner arm and the outer arm is positioned at the same side of the crossing point of the inner arm and the outer arm, one end of the connection between the two connecting rods points to one side far away from the crossing point of the inner arm and the outer arm, one of the connecting rods is fixedly connected with a blocking plate, the cross arm is provided with a cam, the cam is matched with the blocking plate, the rotating center of the cam is installed on the cross arm through a pin shaft, and the cross arm is further provided with an adjusting device which controls the cam to rotate. This technical scheme is through the barrier plate to contact the cam to when the barrier plate contacts the cam, thereby come the restriction height.
