Abstract
An air flap apparatus for a motor vehicle having a driving force source to drive a plurality of air flaps between their operating positions; the apparatus having at least two sub-groups of air flap(s) which are displaceable separately from one another between their operating positions but are drivable by the shared driving force source; there being arranged between the driving force source and the at least two sub-groups a gated control configuration which in order to transfer driving force to different sub-groups has, on a groove carrier rotatable around a rotation axis, at least two control grooves embodied separately and arranged at a distance from one another, into each of which a control pin penetrates, each combination of control pin and control groove being motion-transferringly coupled to a different sub-group, the at least two control grooves are embodied on an enveloping surface of the groove carrier at an axial distance from one another and are coded such that for two sub-groups, they permit at least four different combinations of operating positions.
