The invention provides an automobile seat manual height adjusting device locking mechanism. A height adjusting device is provided with a brake component and a handle driving disc, the brake componentis provided with a brake shaft, the locking mechanism comprises: a locking fluted disc which penetrates through the brake shaft and is installed on the handle driving disc, and an annular boss is arranged on the upper surface of the locking fluted disc; a locking plate which is installed on the locking fluted disc, wherein a kidney-shaped hole is formed in the locking plate, an annular boss on thelocking fluted disc is arranged in the kidney-shaped hole in a relatively sliding mode, a cylindrical pin protruding downwards is arranged on one side of the lower surface of the locking plate, and the cylindrical pin is embedded in the cam sliding groove of the handle driving disc in a sliding mode; partial gear ring characteristics are arranged on the lower surface of the locking plate and between the cam and the kidney-shaped hole, and when the cylindrical pin on the locking plate moves from the far end of the cam chute relative to the brake shaft to the near end of the cam chute relativeto the brake shaft, the locking fluted disc is meshed with the partial gear ring characteristics. The multiple tooth grooves are engaged at the same time, enough large locking torque can be provided,and the problem that front-back collision self-locking of a manual seat height adjusting device is unreliable can be solved.

    本发明提供了一种汽车座椅手动调高装置锁止机构,调高装置设有制动部件和手柄驱动盘,制动部件设有制动轴,锁止机构包括:锁止齿盘,穿过制动轴并安装在手柄驱动盘上,锁止齿盘上表面设置有环状凸台;锁片,安装在锁止齿盘上,锁片开设有一腰形孔,锁止齿盘上环状凸台相对滑动设置在腰形孔中,在锁片下表面一侧设置有向下凸出的圆柱销,圆柱销可滑动的嵌入在手柄驱动盘的凸轮滑槽中;在锁片下表面且在凸轮和腰形孔之间设置有部分齿圈特征,当锁片上的圆柱销由凸轮滑槽相对制动轴远端运动至相对制动轴近端时,锁止齿盘与部分齿圈特征啮合。本发明中多齿槽同时啮合能提供足够大的锁止扭矩,能解决座椅手动调高装置前后撞自锁不可靠的问题。
