Abstract
An arrangement of air flaps for a motor vehicle, comprising an air flap frame which surrounds a through-flow opening, as well as at least one air flap which is movably mounted on the air flap frame, for changing the effective through-flow area of said through-flow opening, said at least one air flap at least protruding into the through-flow opening and preferably extending across said opening; said arrangement of air flaps including a Hall effect sensor and a detection section comprising magnetizable or permanently magnetized material and which cooperates in such a manner with a detecting section of the Hall effect sensor, the Hall effector sensor that detects a magnetic field emanating from the detection section, emits a detection signal when the at least one air flap is in a prescribed reference position relative to the air flap frame, which is different from a detection signal emitted by the Hall effect sensor when the at least one air flap is not in the prescribed position.
