<p>A flap for a ventilator, heater, or air conditioner installation in particular for the cabin of a motor vehicle, comprises a support plate (12) and at least one block-shaped air-guiding blade (20) mounted on said plate. Said block-shaped blade is constituted by at least two thin walls (22, 24) of plastics material which are made on and fixed to said support plate by molding. At least one of said walls is folded back and fixed to the other wall to obtain a a block-shaped blade having a volume which is greater than the sum of the volumes of said thin walls. This avoids the need to add on a plastic or foam block separately.</p> |
