<p>The outlet (10) has air guiding elements such as upper lamellas, middle lamellas and lower lamellas rotatable about parallel axes. The elements are aligned parallel to each other, in one position, and aligned different from each other, in another position. A control device i.e. control wheel (28), moves the elements between the two positions. The control device is coupled with two of the elements by respective coupling parts i.e. toothed racks (22, 24). The control device is coupled with the remaining element by a coupling part i.e. lever arm (26).</p> |
