Motorised roller shutter with motor stop upon detection of obstacle

摘要

The blind has control units (9) controlling stopping of a motor, are defined by a control unit (10), an emitting or modifying unit (12) and a measuring unit. The unit (10) is unwinded inside a slide (6). The unit (12) extends longitudinally inside the slide and emits and/or modifies an electrical signal in continuous manner under the effect of continuous deformation by the unit (10). The measuring unit measures electrical characteristics of the signal and controls stopping of the motor in case of measurement of characteristics corresponding to a contact of an apron (3) with an obstacle.
