The invention discloses a seat folding mechanism. The mechanism comprises a backrest, a seat plate, armrests, a socket and the like, the lower end of the backrest, the rear end of the seat plate and the upper end of the socket are coaxially and rotationally connected through a large joint; the lower ends of the armrests are rotationally connected with the front end of the seat plate through small joints, and a backrest lock is arranged in the backrest; a seat plate lock is arranged in the large joint, and a handrail lock is arranged on the seat plate; the technical scheme is mainly characterized in that the seat plate lock and an armrest lock are mainly designed to be of an integrated linkage folding operation structure, that is, an armrest and a seat plate are subjected to integrated linkage folding by sequentially unlocking the armrest lock and the seat plate lock; specifically, a backrest lock on a backrest is unlocked, and the backrest rotates towards a socket around a large joint; then the armrest lock is unlocked to drive the armrest to rotate around the small joint to be folded on the seat plate, and the seat plate lock is unlocked to drive the folded armrest and the seat plate to rotate around the large joint to be folded on the socket. Therefore, through the armrest lock and the seat plate lock which are ingenious in structural design and reliable in action matching, the folding process of the seat is simpler, more convenient and more labor-saving.

    本发明公开了一种座椅折叠机构,包括靠背、座板、扶手和插座等,该靠背下端、座板后端和插座上端经大关节作同轴心转动连接,扶手下端经小关节转动连接在座板前端,并在靠背内设有靠背锁,大关节内设有座板锁,座板上设有扶手锁,主要是将座板锁和扶手锁设计成一体联动折叠操作的结构,也就是通过依次解锁扶手锁和座板锁来将扶手和座板一体联动折叠,具体是将靠背上的靠背锁解锁,使靠背围绕大关节向插座转动,并解锁扶手锁而带动扶手围绕小关节转动折叠在座板上,以及解锁座板锁而带动折叠后的扶手连同座板一起围绕大关节转动折叠在插座上。因此,通过这种结构设计巧妙、动作配合可靠的扶手锁和座板锁,使得座椅的折叠过程更加简单、方便、省力。
