ABSTRACT:
The invention pertains to a control unit, especially for setting heating, oling and/or ventilation systems in motor vehicles. Sliding members are guided between two end positions in an oblong body. Setting members, e.g., louvers or motors, are adjusted by means of these sliding members via transmission means. A step-down unit is provided as the transmission means, which consists of a first toothed rack molded onto the sliding member and of a second toothed rack molded onto the body, and a gear which is mounted rotatably between the two toothed racks and moved when the sliding member is moved. The gear is connected to an adjusting means, e.g., a rod, which in turn operates the setting member.
