Abstract

A head rest arrangement for a motor vehicle seat includes a back rest frame, a head rest which can be fixed in at least one position of use on the back rest frame and comprises a head rest body for supporting the head of a vehicle passenger, a device for displacing the head rest in the event of a collision, in order to be able to move the head rest body in relation to the back rest frame into a pre-determinable position different from the position of use, and a locking device which counteracts a displacement of the head rest and can be unlocked in a the event of a collision. The head rest arrangement is provided with a device for blocking the displacement device in an unlocked state as long as the head rest is moved out of the position of use.
