Cover elements e.g. laminar underbody covers, for underbody of motor vehicle i.e. car, have elongated recess and/or elevation that runs in direction of air flow, where air flow is self-adjustable in underbody during drive of motor vehicle

摘要

The elements (10-14), have an elongated recess (22) and/or elevation provided in a region of an underbody (1) and runs in a direction of air flow i.e. wall flow line, with a longitudinal extension. The air flow is self-adjustable in the underbody during drive of motor vehicle, where the air flow deviates from a direction of longitudinal axis (L) of the vehicle. The elongated recess receives a fastening element (21) i.e. screw. The elongated recess and/or elevation is in the form of reinforcement ribs (20).
