  • the load bar extending over the entire length of the first end, and the synchronization means are intended to ensure the horizontality of this load bar.
  • the synchronization means being then controlled so that the two load bars are always at the same height, so as to avoid crumpling the screen or soliciting it unsymmetrically.
  • the reference axis is a longitudinal axis of a load bar B connected to the first mobile end of the screen or to a portion of the first movable end of the screen.
  • the control circuit or a part thereof can be integrated in the load bar and comprise one or more accelerometers arranged for example on a plate of circuit board of the control circuit. It can also be provided that the control circuit is able to detect the rotation of each geared motor.
  • each winding drum constitutes a winding spool for a flexible link independent of the screen having a first end attached to the winding spool and a second end intended to be fixed directly or indirectly to a dormant structure or to a load bar.
  • the flexible connection may be constituted by any type of rope, cord, wire, tape or tape adapted to wind on a reel. To avoid having to manage the positioning of successive turns during winding, it is preferable a flat flexible connection ribbon type.
  • the winding coils rotate about the same longitudinal reference axis.
  • the winding coils each turn about two axes parallel and distant from each other.
  • a box defines two housings for the geared motors of the two winding units.

  • This solution offers the additional advantage, compared to a solution with a drum extending the entire length of the screen, to limit the mass at the mobile end of the screen. It should be borne in mind that increasing the mass of a load bar is not proportional to the increase in length, because additional reinforcements must be provided for long lengths, so as to preserve sufficient rigidity to the load bar.

To maximize these advantages, it can be provided in particular that a middle portion of the screen is not wound on any of the winding drums.
