    • A seat back lock is included in a seat back of a vehicle. A knob is provided at the top of the seat back. A passenger in the vehicle pushes down the knob to cause the seat back to move from a standing position to a folding position on a seat. In the standing position, a striker extending from the body of the vehicle engages with a hook of the seat back lock. The seat back lock comprises a binding lever and a warning lever connected to the knob. Whenever the strike engages with the hook, the binding lever directly contacts the striker. If the striker incompletely engages with or disengages from the hook, the knob is pulled down by the warning lever to expose an indicator to permit the passenger to visually recognize it.
    • 汽车座椅靠背中包括座椅靠背锁。 在座椅靠背的顶部设有旋钮。 车辆中的乘客按下按钮使座椅靠背从座位上的立起位置移动到折叠位置。 在站立位置,从车身延伸的撞针与座椅靠背锁的钩接合。 座椅靠背锁包括连接杆和连接到该旋钮的警告杆。 每当撞击与钩子啮合时,装订杆直接接触撞针。 如果撞针与钩不完全接合或脱离接头,则通过警告杆将旋钮向下拉以露出指示器,以允许乘客在视觉上识别。
