AIR GUIDE SYSTEM FOR A MOTOR VEHICLE

摘要

Air guide system (10) for a motor vehicle, comprising a support structure (12) having an air passage opening (14), an air damper assembly (16) having at least one air damper (18) which is provided on the support structure (12) so that it can pivot about a damper axis (20) between a closed position (FIG. 1(a)) and an open position (FIG. 1(c)) in order to adjust a flow cross-section of the air passage opening (14), the flow cross-section being minimal in the closed position (FIG. 1(a)), and the air damper (18) comprising two opposing damper longitudinal edges (22) extending substantially in the direction of the damper axis (20), and an air guide means (24) for guiding air (L) flowing through the air passage opening (14) downstream of the air passage opening (14), wherein the air guide means (24) comprises one or more air guide walls (26), an air guide wall (26) of the air guide means (24) being assigned to at least one, preferably each, air damper (18) of the air damper assembly (16), and, for the respective air damper (18), the assigned air guide wall (26) extending from an air-damper-side edge (28) of the air guide wall (26) away from the damper axis (20) of the air damper (18), and, in a central region of the damper axis, which extends over at most 80 percent of the length (b) of the damper axis (20), the minimum distance (d) of the damper axis (20) of the air damper (18) in the closed position to the air-damper-side edge (28) of the assigned air guide wall (26) is less than the average distance (a) between the damper longitudinal edges (22), preferably less than half, particularly preferably less than a tenth of the average distance (a) between the damper longitudinal edges (22).
