摘要

A window blind has a fan-fold web anchored at the top by a horizontal profile (10) and a lower rail (12) whose synchronized operation is coordinated by a collector cord (111). Both sides of the top rail are linked to a cord wind-up regulator (20) incorporating an operating cord (22) linked to an anchor plug. One end of the operating cord (22) is coupled to a moving plug.
