Claim 11:
12. A roller blind mechanism for a roller blind system comprising a roller blind tube with a blind mounted thereto, the blind being extendable and retractable between upper and lower end positions, the roller blind mechanism having a longitudinal direction and comprising:
a roller blind-stopping system comprising a holding portion, a threaded spindle and a winding stopper;
a limit nut threadedly engaged with the threaded spindle, operatively connectable to the roller blind tube and travelling along the threaded spindle upon extension and retraction of the blind, wherein, in use, the limit nut abuts the winding stopper when the blind reaches one of the upper and lower end positions; and
a mechanism-levelling system fixedly mountable to a roller blind support and defining a roller blind stopper-receiving cavity to receive at least partially the holding portion of the roller blind-stopping system;, wherein the mechanism-levelling system comprises a bottom abutting portion at least partially supporting the holding portion when received in the roller blind stopper-receiving cavity, the bottom abutting portion being configurable into at least two vertical positions so as to adjust a vertical position of the roller blind mechanism.
