The invention relates to a vehicle seat crash safety device (1). The vehicle seat crash safety device (1) has a locking device for locking the height of a cushion frame of the vehicle seat. The actuator (3) is actuated in the event of a collision in order to tighten the belt rope (5) with a pulling force. In the locking position, the locking element holds the locking element of the locking device in the unlocking position. In the release position, the locking element releases the locking element. The locking element is loaded into the locking position by a spring element. According to the invention, the locking element can be moved from the locking position into the release position by means of a frictional force generated by the actuator (3). Preferably, the friction force is generated by a driver (8), such as a friction wheel (9), which is pressed against the belt rope (5). The movement of the driver (8) is coupled to the movement of the locking element. The invention also relates to the use of a vehicle seat for a motor vehicle.
本发明涉及一种车辆座椅碰撞安全装置(1)。该车辆座椅碰撞安全装置(1)具有用于锁止车辆座椅的坐垫框架的高度的锁止装置。促动器(3)在碰撞时被操纵,用于以拉力收紧带绳(5)。锁定元件在锁定位置中将锁止装置的锁止元件保持在解锁位置中。在松开位置中,该锁定元件释放锁止元件。锁止元件由弹簧元件加载到锁止位置中。根据本发明,锁定元件可借助于由促动器(3)产生的摩擦力从锁定位置运动到松开位置中。优选摩擦力由携动件(8)(例如摩擦轮(9))产生,该携动件压到带绳(5)上。携动件(8)的运动与锁定元件的运动耦合。本发明还涉及机动车的车辆座椅的应用。
