The flap arrangement may further include a rib arranged in the region of the sealing lip and outside the sealing surface. The rib may project substantially vertically from the front side of the flap main body, and may serve for air flow rate reduction during opening of the flap. The sealing lip and the rib may be formed in one piece.
