Abstract
The invention concerns a powered rolling shutter whereof the stator of the motor is connected to a fixed support via elastic means (R , R ) for stopping the shutter in high and low abutment when the resisting torque exceeds a selected value, consisting of two springs (R , R ) compressed by the stator rotation. The travel distance ( ) before on of the springs (R ) is compressed is greater than the travel distance ( ) before the other spring (R ) is compressed. The compression is ensured by a mobile element ( ) also actuating a switch ( ). The travels (c , c ) required for activating the switch can be inverted. The motor can be mounted on the left or on the right with a differentiated resisting torque for stopping in high abutment and low abutment.
