Driving air`s volume flow rate reducing device for motor vehicle, has surface section flexible in shape and connected with fastening unit for detachable fastening of surface section, where surface section has reinforcing section at edge

摘要

The device (1) has a surface section (3) for increasing flow resistance of a volume flow rate of driving air, when ventilating a vehicle, where the surface section is flexible in shape. The surface section is firmly connected with a fastening unit (5) for detachable fastening of the surface section. The surface section has a reinforcing section (4) at its outer edge, where the reinforcing section has high mechanical rigidity in comparison to the surface section, and the fastening unit is attached to the reinforcing section.
