<p>The outlet (B) has a base plate (2) provided with an air duct (4). A diffusion grid (10) is mounted on the base plate with respect to an outlet of the duct. The diffusion grid comprises high and low diffusion zones (110, 120) comprising ribs (112, 114, 122) to selectively direct the circulation of flow of air in two different directions. A cover selectively covers one of the zones. Some ribs of one of the zones direct the flow of air along axial direction parallel to a longitudinal axis (X-X') of the duct.</p> |
