Abstract
The invention relates to a screen device () comprising a screen () movable between a retracted position and a deployed position, bearing on a load bar (), and motorized by an installation comprising at least two winding units (), each comprising a winding coil () associated with a driving gear motor (), the winding coils () being guided to rotate relative to the box () mechanically independently from one another. A control circuit () synchronizes the two winding units () by driving each gear motor () so as to ensure the horizontal position of the load bar. To that end, the control circuit () is connected to one or more sensors (), for example accelerometers, delivering a signal representative of the levelness of the load bar.
