Patent

CA 2158702

The present invention pertains to a cassette blind with a weighting profile at the lower end of a set of blinds and with a blind drive, in which coupling elements with a winding shaft mounted in the cassette profile, complementary coupling elements with a drive member and complementary coupling elements at a pin which can be stationarily fastened are arranged, wherein coupling elements of the drive member and of the winding shaft mutually engage each other during a rotary movement of the drive member in the winding-up direction of the blinds, and coupling elements of the winding shaft and of the pin mutually engage each other in the opposite direction. The coupling elements at the winding shaft are arranged rotatably over a predetermined angle against spring action in the winding- up direction of the blinds in order to achieve a torsionally elastic tensioning of the weighting profile at the cassette profile at the end of the winding-up movement of the blinds.
