The assembly is especially designed for use on roof openings or sunroofs closeable by a lid. The assembly is characterized in that a generator is coupled to a component of the automobile which revolves during traveling and the rotational speed of which is directly proportional to the speed of travel. A control signal directly proportional to the speed of travel is obtained from the generator by means of which the adjustment drive for the ventilation device can be switched on according to the speed of travel. The adjustment drive can be switched on in the direction of closing the ventilation device at a higher speed and in the direction of opening at a lower speed.
