Air flaps having a symmetrical cross-sectional profile and arrangement of air flaps for a motor vehicle with such an air flap

摘要

The present invention relates to an air flap for an air passage with a variable flow cross-section on a motor vehicle, wherein the air flap (10; 110; 210) in the axial longitudinal direction (l) along a air damper shaft (l), about which the air flap (10; 110; 210) is rotatable, wherein the air flap (10) further in a for air damper shaft (l) orthogonal direction of width (b) and wherein the air flap (10; 110; 210) in a both for air damper shaft (l), as well as to the direction of width (b) orthogonal direction of thickness (d), wherein the maximum dimension of the air flap (10; 110; 210) in the direction of the thickness (d) is smaller than the maximum dimension in the direction of width (b) and this in turn is smaller than the dimension in the longitudinal direction (l), characterized in that an outer contour (16; 116; 216) of a cross-sectional profile of the air damper (10; 110; 210) when viewed in a to the intersecting plane orthogonal air damper shaft (l) at least along a axial symmetry along section is mirror symmetrical with respect to a plane of symmetry (se), which extends in the axial direction (l) and in the direction of the width (b), preferably the air damper shaft (l).
