ABSTRACT:
An arrangement is described for pivoting a flap (5) relative to an air duct (1), as used for example in a vehicle heating and ventilation system. A first actuating element (7a) is connected by film hinge (8) to a base plate (4) on the duct, and a second actuating element (7b) is connected by film hinge (9) to the flap (5). The actuating elements (7a) and (7b) are further hinged to each other along a film hinge (10). Movement of the actuating elements 7a, 7b for example by means of a Bowden cable (12) rotates the closure flap (5) about its film hinge (6).
