The invention relates to a vehicle seat crash securing device () used for a vehicle seat of a motorized vehicle. The vehicle seat crash securing device () comprises a locking device for locking a height of a seat cushion frame. An actuator () is actuated in the case of a crash for tightening a belt rope (). A blocking element in a blocking position holds a locking element of the locking device in an unlocked position. In a releasing position, the blocking element releases the locking element. The locking element is biased by a spring element into the locked position. The blocking element can be moved by a friction force generated by the actuator () from the blocking position into the releasing position. Preferably, the friction force is generated by a follower () (e.g. a friction wheel ()), the follower () being pressed against the belt rope (). The movement of the follower () is coupled to the movement of the blocking element.
