The invention relates to an overturning locking mechanism of an automobile seat backrest, which comprises a seat frame and two hinge assemblies symmetrically arranged on the left side and the right side of the seat frame, the hinge assembly comprises a hinge strip rotationally connected to the outer wall of the left side or the right side of the seat frame and a locking shaft transversely fixed to the outer wall of the corresponding side of the seat frame, located behind the rotation axis of the hinge strip and used for supporting and positioning the hinge strip. The locking assembly is arranged between one hinge strip and the seat frame; the locking assembly comprises a locking piece, and the middle of the locking piece is rotatably connected to the outer wall of one hinge strip and always has the trend of elastic reset rotation in the clockwise direction. On the premise that the safety performance of the automobile seat is ensured, the requirement for installing an angle adjuster is omitted, so that the manufacturing cost is effectively reduced, the assembling difficulty is effectively reduced, and the assembling efficiency is improved.

    本发明涉及一种汽车座椅靠背的翻转锁止机构,包括座架以及两个对称设于座架左右两侧的铰链组件,铰链组件包括可转动的连接在座架左侧或右侧外壁上的铰链条以及横向固定在座架的对应侧外壁上并位于铰链条的回转轴线的后方以用于对铰链条进行支撑和定位的锁止轴;还包括设于其中一个铰链条与座架之间的锁止组件;锁止组件包括锁止片,锁止片的中部可转动的连接在其中一个铰链条的外壁上并始终具备朝顺时针方向弹力复位转动的趋势;本发明在确保汽车座椅安全性能的前提下省去了安装调角器的必要,从而有效降低了制造成本,而且还有效降低了装配难度以提高了装配效率。
