Abstract

The automatic roller blind has shaft (1) on which the blind is wound, supported at each end in a pillow-block (5) by means of a sleeve integral to the shaft. One of these sleeves cooperates with a non-return catch mechanism located in the corresponding pillow- block, while the other sleeve (10) is mounted on a shaft (11), locked while rotating in the corresponding pillow-block (5) by its outer end, on which is inserted a return spring (14) attached at one end to the sleeve and at the other to the inner end of the shaft (11). The sleeve associated with the shaft (11) has a stop on its inside wall which engages with at least one protrusion on the shaft, locking it.
