Abstract
The invention relates to a drive unit for a closure of an open roof construction. It comprises an electric motor having a drive shaft and transmission means and an electric circuit including said motor and control means to actuate the motor. An emergency clutch is coupled to at least one of the drive shaft and the transmission means and is reachable to enable hand actuation of the movable part in case of an emergency. The emergency clutch is covered by a part of the electric circuit, which must be disconnected to reach the clutch. The part of the electronic circuit is provided on a breakable seal, which is a pierceable metal foil strip. As a result it is possible to observe the use of the clutch, either visibly or electronically.
