• This opening is usually located at the end of the defrost duct.
• the arrangement of the ducts has been modified so that the second duct withdraws the air at the center of the opening of the defrosting duct, the first duct withdrawing the air on the sides of the same opening of the defrosting duct, on both sides of the second duct.

• the area of the dashboard located in front of the opening of the defrosting duct has a certain rigidity, which can be detrimental to a pedestrian in case of pedestrian impact. Deporting the channels towards the rear of the opening of the de-icing duct would furthermore lead to pressure losses in the duct because of the making of a pronounced rear bend, the opening of the de-icing duct being in inclined effect from bottom to top towards the windshield.
