Drive arrangement for sliding roofs, window panes and other similar members in motor vehicles

摘要

A drive arrangement for sliding roofs, window panes, and other similar sliding members of motor vehicles is constructed for motorized operation and also for emergency manual operation. According to a preferred embodiment, the driving shaft of the drive arrangement has a first part of a clutch constrained from movement therewith and a second part displaceably mounted relative to the first part for interconnecting the drive motor with a drive pinion and for disengaging the drive pinion from the drive motor in a second relative position of the clutch parts. The driving force transmittable between the above-noted clutch parts is controlled by an adjustment member mounted on the driving shaft. The adjustment member can be connected to a manually operable handle for emergency operation of the sliding member by a handle through the use of a locking member which secures the adjustment member relative to the driving shaft in a plurality of positions.
