The invention solves the problem of constructing such a head-rest of a seat in a vehicle, especially in a car, which can be moved manually or by means of remote control from the passive to active position and vice versa. According to the invention the head-rest is made up of the movable back squab (2) which is rotationally connected with the back of the seat, with the rotation plane of the back squab (2) being approximately corresponding to the plane of the back of the seat. The pin (3) is permanently connected with the back squab (2) and it rotates inside the sleeve (4) which is connected with the back of the seat. The pin (3) is connected with the blocking pad (5) furnished with the blocking's seat (6) with which the elastically supported locking pin (7) is mated. From the locking position the locking pin (7) is moved by means of either the lever (9) or electromagnet (11). In the second version the back squab (2) is moved by means of the worm gear.
