The invention relates to a fixed-point return mechanism integrated with a maintaining function, which comprises a base, a connecting rod, a cam, a check block and a trigger, wherein the connecting rodis rotatably connected to the base around a first pivot shaft, the cam and the connecting rod are relatively fixed, the check block is rotatably connected to the base around a second pivot shaft andis matched with the cam on a first plane, and the trigger is rotatably connected to the base around the second pivot shaft and is matched with the connecting rod on a second plane. The automobile seatprovided by the invention comprises the fixed-point return mechanism with the integrated maintaining function. According to the invention, the interlocking function is maintained through the triggermatched with the connecting rod to ensure that the seat does not retreat accidently, fixed-point return is achieved through the check block matched with the cam, after the trigger is knocked off to remove the interlocking function, the cam is driven to press the check block open through retreating of the connecting rod to remove the fixed-point function, the structure is simple, the function is reliable, failure is not likely to happen, and the sliding rail is free of a clamping stagnation phenomenon.
本发明涉及一种集成保持功能的定点回位机构,其包括基座、连杆、凸轮、挡块和扳机,其中,连杆围绕着第一枢转轴可转动地连接在基座上,凸轮与连杆相对固定,挡块围绕着第二枢转轴可转动地连接在基座上并在第一平面上与凸轮配合,扳机围绕着第二枢转轴可转动地连接在基座上并在第二平面上与连杆配合。根据本发明的汽车座椅,其包括上述的集成保持功能的定点回位机构。本发明通过与连杆配合的扳机来实现保持互锁功能,确保座椅不会意外回退,通过与凸轮配合的挡块来实现定点回位,在扳机撞开解除互锁功能后,通过连杆回退驱动凸轮压开挡块解除定点功能,不仅结构简单,而且功能可靠不容易失效,滑轨无卡滞现象。
