ABSTRACT:
A flap arrangement, especially for a ventilation or airconditioning system or vehicles, has two flaps which are pivotable about pivot axes parallel to one another and which are coupled to one another for the oppositely directed pivoting movement. The coupling is made via a coupling rod articulated on the two flaps. To achieve a pivoting angle of the same amount on both flaps, the articulation points are so determined that, on the one hand, the radius of the circular paths described by them during the pivoting of the flaps is of equal size and, on the other hand, during the pivoting of the flaps, an imaginary effective straight line respectively connecting the two articulation points rotates about an imaginary center of rotation located approximately in the middle between the two pivot axes.
