Claim 12:
13. A roller blind actuation assembly for a roller blind system comprising a roller blind tube, the roller blind actuation assembly comprising:
a. an actuation shaft having an actuation axis;
b. first and second roller blind actuation cables having each a spool-mounting end portion and a free end portion;
c. a first roller blind-operating system pivotably mounted to the actuation shaft and comprising:
i. a first driving assembly having a first spool member, the spool-mounting end portion of the first roller blind actuation cable being engaged therewith to rotate the first driving assembly about the actuation axis in a first direction when a pulling force is exerted on the free end portion thereof; and
ii. a first unidirectional angular coupler selectively couplable to the roller blind tube upon rotation of the first driving assembly about the actuation axis in the first direction;

d. a second roller blind-operating system pivotably mounted to the actuation shaft and comprising:
i. a second driving assembly having a second spool member, the spool-mounting end portion of the second roller blind actuation cable being engaged therewith to rotate the second driving assembly about the actuation axis in a second direction opposed to the first direction when a pulling force is exerted on the free end portion thereof; and
ii. a second unidirectional angular coupler selectively couplable to the roller blind tube upon rotation of the second driving assembly about the actuation axis in the second direction; and

e. a biasing member operatively coupling the first and second driving assemblies and arranged between first and second unidirectional angular couplers.
