Abstract

A motor vehicle roof arrangement having a cover that can be slid and/or tilted out with respect to an opening in the roof. The cover is movable by means of an electric motor through at least one incompressible driving cable. The electric motor is mounted at a front side of the opening in the roof on a stationary part of the roof, and by means of a secondary drive wheel of an intermediate drive, drives a pinion that is engaged in the driving cable. The pinion is arranged in a front rain groove of a roof frame essentially on the center longitudinal axis of the roof of the motor vehicle. The intermediate drive is located in a gear housing to which the electric motor is flanged to form a drive unit. A secondary drive gear of the intermediate drive is detachably connected with a shaft of the pinion by mating internal and external gear elements. The drive unit comprising the electric motor and the intermediate drive can be exchanged for a hand crank having gear elements that correspond is shape to gear elements of the secondary drive gear without modification to the remainder of the roof arrangement.
