    • In a vehicle seat, two front and two rear links are pivotally connected between a seat cushion frame and a floor of vehicle. Each of the two front links has an arcuate gear region meshed with a corresponding pinion provided to the seat cushion at a point backwardly of that arcuate gear region. Two connecting links are pivotally connected between the respective two front and rear links, such that forward pivot points respective of the two connecting links in the respective two front links are always maintained forwardly of the respective pinions, irrespective of vertical rotation of the two front links. In the case of rear-end collision, such link arrangement allows an excessive backward and downward load to be transmitted through the two connecting links and front links to the two lateral sides of seat cushion frame and dispersed therein, thereby absorbing a corresponding excessive impact.
    • 在车辆座椅中,两个前部和两个后部连接件枢转地连接在座椅坐垫框架和车辆地板之间。 两个前连杆中的每一个具有与在该弓形齿轮区域的后方的点处设置到座垫的相应小齿轮啮合的弓形齿轮区域。 两个连接链节枢转地连接在相应的两个前连杆和后连杆之间,使得相应的两个前连杆中的两个连接连杆相对应的前枢轴点总是保持在相应小齿轮的前方,而不管两个前连杆的垂直旋转 。 在后端碰撞的情况下,这种连杆装置允许过度的向后和向下的负载通过两个连接链节和前连杆传递到座垫框架的两个侧面并分散在其中,从而吸收相应的过度冲击。
