Support for flattened shaft end of roller blind

摘要

The support has a bearing opening (6) adapted to the cross-sectional shape of the shaft end and an assembly slit (16). The slit is fitted with a detent lock (27) acting against the dismantling direction and the bearing opening is turned opposite the direction of the slit in the turning direction of the coil spring. The detent lock is resilient like a barb. The support is defined on its side remote from the blind by a surface running in a sectional plane parallel to the window plane perpendicular to the axis of the bearing opening and inclined in a sectional plane perpendicular to the window plane.
