ABSTRACT:
A roller blind includes a reversable electric motor disposed in and arranged to drive a roller winder via a reduction gear to roll-up and unroll the blind. The motor is switched off at an open and closed position of the blind by limit switches actuable by a control device drivable with the winding roller. The control device includes at least one actuating mechanism provided with first and last rotatable members. The first rotatable member can be brought into geared connection with the winding roller and the last rotatable member is associated with at least one of the limit switches and is provided with an actuator member to actuate the limit switches. The maximum rolling or unrolling-up length of the roller blind is arranged to correspond to an angular rotation of the last roller of less than 360.degree..
