Abstract
An air outlet device is to grant in its closing position a tight closing e from whistling noises. This is to be achieved by simple means and despite component tolerances. For this purpose longitudinal gaps formed between a closure flap and seat edges before the closing process narrow towards that end of the closure flap which is remote from the actuating part. During the closing movement the closure flap is distorted elastically so that the longitudinal gaps close at first in the sections remote from the actuating part.
