The invention discloses a seat backrest unlocking mechanism. The mechanism comprises a rotary support body, and a backrest supporting plate which can rotate relative to the rotary support body; a control part is mounted on the backrest supporting plate; one end of the control part is movably connected with a limiting component through a first elastic element; an assembling hole is formed in the backrest supporting plate corresponding to the limiting component; a limiting hole is formed in the rotary support body; in a locked state, the limiting component penetrates through the assembling holeand is kept in the limiting hole through the first elastic element, the rotary support body and the backrest supporting plate are combined into a whole, the limiting component can overcome the resistance of the first elastic element to be disengaged from the limiting hole by controlling the control part, and the backrest supporting plate can rotate relative to the rotary support body under the action of external force. The seat backrest unlocking mechanism has the beneficial effects that the mechanism has extremely high locking strength in a locking state, the backrest supporting plate can bekept fixed relative to the rotary support body even under severe conditions such as automobile collision, and the safety coefficient is high.

    本发明公开了一种座椅靠背解锁机构,包括转动支撑体,以及能够相对转动支撑体转动的靠背支撑板,靠背支撑板上安装有操纵部件,操纵部件一端通过第一弹性元件活动连接有限位构件,靠背支撑板对应限位构件的位置设有装配孔,转动支撑体上设有限位孔,在锁止状态下,限位构件穿过装配孔,并通过第一弹性元件保持在限位孔内,将转动支撑体和靠背支撑板结合为一体,操控操纵部件能够使限位构件克服第一弹性元件的阻力脱离限位孔,使靠背支撑板能够在外力作用下相对于转动支撑体旋转。本发明的有益效果是:在锁止状态下具有极高的锁定强度,即便是在车辆发生碰撞等恶劣情况下,靠背支撑板也能相对转动支撑体保持固定,安全系数高。
