Draft deflector for sliding roofs, removable roof sections or the like of motor vehicles

Year	Description
1991	Invention patented by Jens Eberius and Hans-Martin Gerhard on September 17th, 1991. Abstract: A draft deflector for a sliding roof is disclosed for a removable roof section or the like. The deflector exhibits an airfoil profile which extends in the transverse direction of the vehicle, is arranged adjacent to a front edge of the roof opening and can be moved from a sunk inoperative position to a swivelled-up operative position and vice versa. In the operative position, the airfoil profile extends at a negative setting angle and projects beyond an imaginary roof contour at least in sections in the upward direction. In order to reliably avoid, during the driving operation, when the roof is open, the occurrence of annoying low-frequency vibrations in the vehicle interior (sliding roof rumbling) and to essentially maintain the aerodynamic drag of the vehicle, it is provided that the airfoil profile, in the operative position, is arranged such that it is ensured that the air current occurring in the driving operation flows around the airfoil profile on both sides.
