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.
Claims19
A vehicle roof assembly, comprising:
- a roof panel having an opening;
- a cover member that is selectively moveable relative to the opening to selectively close the opening;
- a first belt associated with a driving member near one side of the cover member;
- a second belt associated with a driving member near a second side of the cover member;
- and
- at least one drive member that engages the belts and rotates each belt about a loop to move the cover relative to the opening, the drive member comprises a pinion and each belt wraps around a portion of the pinion.

A vehicle roof assembly, comprising:
- a roof panel having an opening;
- a cover member that is selectively moveable relative to the opening to selectively close the opening;
- a first belt associated with a driving member near one side of the cover member;
- a second belt associated with a driving member near a second side of the cover member;
- and
- at least one drive member that engages the belts and rotates each belt about a loop to move the cover relative to the opening;
- a guide frame with frame cross pieces and lateral frame parts, wherein the drive member comprises one common driven, rotatable toothed pinion supported on one of the frame cross pieces of the guide frame, the toothed pinion being partially wrapped by the two belts at different levels, each of the belts being guided about a deflection element approximately at the end of one of the lateral frame parts, an axial height of the common rotatable toothed pinion corresponding approximately to the combined width of the belts.
4 more elements
A drive device for a motor vehicle sliding roof panel, comprising:
- two flexible belts having an inner surface including teeth, one belt being associated with each side of the sliding roof panel;
- and
- at least one drive member having an externally toothed surface that engages the teeth on the inner surfaces of the belts to synchronously rotate the belts about belt loops in a manner that causes sliding movement of the sliding roof panel.
