摘要： A pair of separable hinge assemblies mount a seat cushion on a vehicle for positioning between a rearwardly folded regular seating mode and a forwardly folded stored mode. The hinge assemblies each comprise a body-half hinge plate mounted to the vehicle body and a seat-half hinge plate mounted to the seat cushion hardened undersurface. The body-half plate has upstanding side webs each formed with open end mirror image slots adapted to releasably capture a pintle pin extending transversely between parallel ear portions of the seat-half hinge plate. Each ear portion includes mirror image first and second cam shoulders adapted to frictionally retain the hinge assemblies in their respective seating or folded modes. Upon placement of the seat cusion in an intermediate position both sets of cam shoulders of each seat-half hinge plate are spaced from their associated body-half plate camming surfaces. An improved fail-safe arrangement provides arcuate-shaped guide prongs on the seat-half hinge plate adapted for reception in aligned apertures in the body-half hinge plate with the plates in positive full engagement. If, however, the hinge plates are not properly engaged the seat-half hinge plate guide prongs are moved into rocking contact with the body-half hinge plate preventing the seat cushion from being folded to its regular seating position.
摘要翻译：一对可分离的铰链组件将座垫安装在车辆上，用于在向后折叠的正常就座模式和向前折叠的存储模式之间定位。铰链组件各自包括安装到车体的主体半铰链板和安装到座垫硬化下表面的座半铰链板。主体半板具有直立的侧腹板，每个腹板均形成有开口端镜像槽，其适于可释放地捕获在座半铰链板的平行的耳部之间横向延伸的枢轴销。每个耳部包括镜像第一和第二凸轮肩部，其适于摩擦地将铰链组件保持在它们各自的座位或折叠模式中。在将座位插入件放置在中间位置时，每个座半铰链板的两组凸轮肩部与其相关联的半体半凸轮表面间隔开。改进的故障安全装置在座椅半铰链板上提供弧形导向插脚，其适于在主体半铰链板中的对齐的孔中接收，板正面完全接合。然而，如果铰链板没有适当地接合，则座半铰链板引导插脚被移动到与主体半铰链板的摇摆接触中，防止座垫折叠到其正常的就座位置。
