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

A draft deflector movable between an inoperative position and an extended operative position for a motor vehicle having a roof contour, a front, and a rear, comprising:

• a roof opening, having a front edge, formed in the motor vehicle;
• an airfoil profile, having a front boundary edge, a top surface and a bottom surface, extending in a transverse direction of the motor vehicle and arranged adjacent to said front edge of said roof opening;
• and
• adjusting mechanisms arranged at both longitudinal sides of the opening, for moving the draft deflector from the operative position to the inoperative position;
• wherein each adjusting mechanism has first and second levers which are arranged crosswise with respect to one another;
• wherein, in the operative position, the first lever connects an end area of the draft deflector which is in the front viewed in the driving direction with a rear roof-side linking point, whereas the second lever extends between a rear end area of the draft deflector and a front roof-side linking point;
• wherein both levers are in an operative connection in a crossing area in such a manner that a set-off pin of the second lever engages in a longitudinal slot guide of the first lever and is displaceably guided in it;
• and wherein, when in the operative position, said airfoil profile forms an acute angle with respect to a horizontal plane and has a transverse cross-section spaced apart from and above the roof contour, said front boundary edge of said airfoil profile forming a gap having a height of approximately 5 to 15 mm with the roof contour, and being spaced rearward of said front edge of the roof opening, allowing air currents flowing around both the top and bottom surfaces of said airfoil profile to act upon the top and bottom surfaces forcing the air currents away from the roof opening.
