Abstract
A cable drive device for moving a vehicle component, such as a vehicle sliding roof, includes a cable that is guided in an endless loop and whose ends of which are wound up on two winding drums that are driven in the same direction. An intermediate section of the cable is looped around a further winding drum, thereby dividing the cable into two branches having entrainment elements provided thereon for engaging the vehicle component to be moved.
Claims17
A drive device for moving a vehicle component, comprising:
- at least one flexible traction transfer means that is guided in the form of a loop and has a first end and a second end;
- at least a first winding drum associated with the first end and a second winding drum associated with the second end, wherein the first and second winding drums are adapted to have the first and second ends of said at least one flexible traction transfer means wound up on and unwound from the first and second winding drums, respectively;
- a drive that rotates the first and second winding drums in a same rotational direction;
- at least one entrainment element secured to said at least one flexible traction transfer means and the vehicle component;
- at least one further winding drum coupled to the drive, wherein said at least one further winding drum is looped around by an intermediate section between the first and second ends of said at least one traction transfer means to form at least two branches of said at least one flexible traction transfer means,
- wherein said at least one entrainment element is fastened to one of said at least two said branches.
