Assembly for generating adjustment movements at automobile ventilation devices
First Claim
1. In combination an assembly generating adjustment movements on automobile ventilation devices driven by motor drive means, especially on roof openings closeable by a slideable or pivoted lid comprising:
- a generator coupled to a component of the automobile which revolves during travelling and the rotational speed of which is directly proportional to the speed of travel, said generator generating a control signal to adjust said drive means for the ventilation device which is switched on according to the speed of travel, in the direction of closing the ventilation device at a higher speed and in the direction of opening at a lower speed;
said switching on of the drive means is carried out optionally for two different ranges of travel speed, one for town driving and the other for country driving;
said drive means can be selectively switched on.

Abstract
An assembly which is to be used for generating adjustment movements on automobile ventilation devices driven by electric motors. 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.
