ABSTRACT:
A telescopic winch for tilting a cover closing a roof opening in a motor vehicle, with a plurality of threaded parts, screwable into one another, of which the outermost or innermost is connected with an axially fixed wheel and the other threaded part is connected with the cover. In order to make a telescopic winch of this type electrically drivable and to provide it with an emergency manual drive, provision is made for a crown gear to be on an outside jacket of the wheel, said crown gear being in mesh with a worm shaft of an electric motor unit, and for the mesh between the crown gear and worm shaft to be releasable. Separation between the crown gear and the worm shaft can be accomplished either by removing the wheel or by pivoting the electric motor unit.
