  • Patent number: 5954251
    Abstract: A mounting device for roof racks on motor vehicles, especially automobiles, includes mounting elements located in longitudinal roof channels in which the endwise supporting parts of the roof racks can be secured. Each mounting element is formed by a base plate that rests on the bottom of the roof channel and is fastened thereto, on which plate at least one threaded section is formed for screwing in a mounting bolt for the supporting part. In order for high roof loads to be carried by the mounting device and readily conducted into the fixed body, on the underside of an upright rib of the supporting part, at least one supporting surface is provided that forms a sloping plane relative to the screwing direction in the transverse direction of the vehicle. The supporting surface abuts a corresponding supporting surface of the base plate that extends in the same direction and projects upward.
