US Patent 7464979 Wind deflecting device

A wind-deflecting and wind-guiding device is disposed in the region of a windshield of a motor vehicle. The device is formed, in particular, as a cowling extending in the transverse direction of the vehicle. A prestressing device biases lateral longitudinal end regions of the wind-deflecting device in the direction of the vehicle and in the direction of the windshield and, as a result, effectively prevents said longitudinal end regions from lifting off, even under temperature loadings.
