Abstract
Various embodiments of a drive device for motor vehicle sliding sunroofs or the like are proposed, in which the drive cables wound with wire in screw thread-like manner used hitherto as drive transmission elements in particular for the drive of the displaceable cover but also for the drive of displaceable shading or wind deflection elements are replaced by endless, tensile stress-resistant, low-noise guided toothed belts.
Claims21
A drive device for motor vehicle sliding sunroofs, having two flexible drive transmission elements which are in driving connection, one on one side and the other on an opposite side of a displaceable element that is displaceable in one direction or another direction of movement, in the form of a cover of the sliding sunroof construction, with guide components for the displaceable element, and which may be synchronously displaced in the one or the other direction of movement by engagement with a rotatable toothed pinion, which may be selectively driven in one or another direction of rotation;
- wherein the two flexible drive transmission elements take the form of endless, tensile stress-resistant toothed belts, which are provided on an inside thereof with internal toothing complementary to the toothing of the pinion, wherein deflection of the two toothed belts takes place at one end in each case with partial wrap of the pinion and at the other end in each case by means of a deflection element.
