Embodiment Construction

[0020] according to figure 1 A flap arrangement 1 according to the invention, in particular for a vehicle air-conditioning system 2 , has a housing 3 and has a flap 5 mounted in said housing 3 so as to be pivotable about an axis 4 . In this case, the flap 5 serves to regulate the air flow in the housing 3 and has a flap body 6 with a front side 7 which, in the operating state, is arranged on the air inflow side. According to the invention, an elastic sealing lip 8 with a sealing surface 9 is now arranged on the flap body 6 , wherein ribs 10 are arranged in the region of the sealing lip 8 and on the outside of the sealing surface 9 , said ribs 10 Protrudes substantially vertically from the front side 7 of the flap body 6 and serves to reduce the air velocity during opening of the flap 5 , wherein the sealing lip 8 and the rib 10 are formed in one piece.

[0021] in accordance with image 3 Looking at the flap 5 in the detail illustration of , it can be seen that the free edge...

Abstract

The invention relates to a flap arrangement (1), especially used for a vehicle air conditioning system (2). The flap arrangement may include a housing and a flap arranged in the housing for regulating an air flow in the housing. The flap may have a flap main body with a front side arranged on an air inflow side in an operating state. The flap arrangement may also include an elastic sealing lip with a sealing surface provided on the flap main body. 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.

Description

technical field [0001] According to the preamble of claim 1 , the invention relates to a flap arrangement, in particular for a vehicle air-conditioning system. The invention also relates to an air conditioning system having at least one such flap arrangement. Background technique [0002] DE 10 2007 036 824 A1 already discloses a general flap device with a housing and with a flap arranged in the housing for regulating the air flow in the housing, wherein the flap has a flap body with a front The front side is arranged on the inflow side at least in the operating state, and the rear side is arranged on the side avoiding the air flow. In this case, on the rear side of the flap body, an air guide element extending at an oblique angle relative to the rear side of the flap body is arranged. In this way it is especially intended to be able to at least minimize the annoying howl when opening and closing the flaps. [0003] Another flap arrangement with flaps is known from EP1783...
