Hand crank-operated emergency drive of a drive unit which can be driven by means of an electric motor, in particular for sliding roofs of motor vehicles, the drive unit having a transmission connected to the electric motor and whose drive component (4), which emerges from the transmission, interacts with the mechanism to be actuated. An emergency actuation component (5) which is prestressed with a spring (10) engages in its position corresponding to the normal operating state of the drive unit in the drive component (4) in a positively locking manner and in a coaxial transmission gearwheel (3) in such a way that the emergency actuation component (5) can be moved under slight pressure, counter to spring force, axially out of engagement with the transmission gearwheel (3), by means of an emergency actuation tool (15) which can also be inserted into said wheel in a positively locking manner, and into an emergency actuation position in which it is only engaged with the power-output component (4). …<IMAGE>… |
