The invention provides an automobile seat backrest folding mechanism, and relates to the technical field of automobile seat folding equipment.The automobile seat backrest folding mechanism comprises a seat framework and an arm-chair framework, an electric cylinder is arranged at the bottom of the seat framework, a movable plate is fixedly connected to one side of the electric cylinder through a connecting rod, and the bottom of the seat framework is slidably connected with the movable plate through a sliding block; according to the invention, through the arrangement of the stabilizing mechanism, when the electric cylinder drives the movable plate to move at the bottom of the seat framework, the sliding effect of the sliding pins in the limiting sliding grooves at the two ends of the arm-chair framework is realized; compared with traditional folding operation, the structure can share stress of the seat framework and the arm-chair framework to the positions of the sliding pins, and therefore stress damage to the connecting position of the seat framework and the arm-chair framework is reduced.

    本发明提供一种汽车座椅靠背收折机构,涉及汽车座椅收折设备技术领域,包括座椅骨架和靠椅骨架,所述座椅骨架的底部设置有电动缸,所述电动缸的一侧通过连杆固定连接有活动板,且座椅骨架的底部通过滑块与活动板之间滑动连接,所述座椅骨架的一端设置有分级机构,且靠椅骨架通过分级机构与座椅骨架之间活动连接,本发明通过设置的稳定机构,在电动缸带动活动板移动咋子座椅骨架的底部时,实现滑动销在靠椅骨架两端限位滑槽内部滑动效果,相比传统的收折操作,该结构能将座椅骨架和靠椅骨架的受力分担到滑动销位置上,从而降低座椅骨架和靠椅骨架连接位置发生受力损坏。
