Abstract (en)
[origin: EP0839988A1] The roller blind has a tube on which the blind is rolled or unrolled, a drive motor (M) and a reduction gear system. At each end of the shutter there is a housing (2) covered by a plate (3) designed to support one end of the tube and creating a narrow space holding the reduction gear assembly (20). The reduction gear assembly has a central gear which engages with a driving pinion, either direction or through an intermediate gear. The central gear and driving pinion can be cylindrical in shape with parallel axes and straight or helicoid teeth, or they can be in the form of bevel gears; the central gear can also be driven through an endless screw.
