Abstract
An airflow control device for air streams in a motor vehicle air-conditioning system includes an installation frame with pivotable lamellae (2) that are driven by an electric motor via a gear mechanism arranged on the outside of the frame. The gear mechanism comprises a plurality of cylindrical gearwheels (9 to 12) arranged one above the other, so as to be very narrow and such that the overall dimensions of the housing (5) for the gear mechanism do not exceed the width and height dimensions of the frame (1). This novel arrangement allows integration of the drive as a whole and minimizes the amount of space required.
