Electrically operated roller blind for providing sun, heat and sound protection for window

摘要

The blind has a driven roller shaft onto which the blind material is wound, with a weighting rod (7) attached to the bottom end of the blind (4), the weighting rod closing the opening for passage of the roller blind formed in the roller housing (11) when the roller blind is in the uppermost position, cooperating with at least 2 stops (17a,17b).
