Abstract
The invention relates to a mechanical adjusting device for an adjusting element, for example an air flap (2) in an air channel (1) of a ventilation system in the passenger compartment of a motor vehicle. The mechanical adjusting device comprises two toothed wheels (5, 6) that mesh with one another, one of which wheels (6) comprises an operating wheel (17) and the other of which toothed wheels (5) is connected to an air flap so as to rotate therewith. By the overcoming of a pressure point created by a raised base (13) between two teeth, the air flap (2) is held in a closed position. The invention provides a stiffening element (15), for example in the form of a spoke, which braces the toothing (7) of one of the toothed wheels (5) in a chordal direction and thereby increases the bias with which the air flap (2) rests in position.
