Means for holding a flap which is rotatably mounted in a conduit, and housing containing said means, for a vehicle air conditioning installation

摘要

In an installation for heating, ventilating or air conditioning the cabin of a motor vehicle, a conduit (10) has a wall (20) over which the edge of a flap (15) passes during travel of the flap to control the flow of air in the conduit. The wall has a rib or thickening (25) which engages the edge of the flap by friction to prevent the flap from moving away from a position to which it has been set.
