ABSTRACT:
A drive arrangement for moving a glass panel of a window of a vehicle has a motor and an input member connectable with the motor means for moving the glass panel. The input member is rotatable in two opposite directions so as to close or to open the glass panel. At the same time, the input member is displaceable between a first position in which it is coupled to a drive shaft of the motor and is rotated by the latter, and a second position in which the input member is uncoupled from the motor so as to be rotated by hand. A lock is provided which is inoperative in the position when the input member is coupled to the motor, and is operative in the position when the input member is uncoupled from the same. When the lock is operative permits rotation of the input member for closing the glass panel, but does not permit the rotation for opening of the latter so that unauthorized opening of the glass panel is prevented. The lock is formed as an overrunning lock provided with a locking element.
