An unlocking assembly for a feedback window curtain set, which is applicable for use in a window curtain set provided with a self-rewinding curtain having an automatic and feedback mechanism. When the curtain has been released to its lowermost position, the unlocking assembly for the entire unit unlocks a locking device. Free ends of lower sections of the pull cords pass through the underside of the counterweight pendulum rod to enable the pull cords to add to an unlock travel distance. The displacement length of the unlock travel distance is used to actuate a locking device of a winding unit, which enables unlocking the locked state of the curtain. Accordingly, when the curtain is released to any height, an unlocking operation can be effected at any time that rewinds the entire system, thus avoiding danger from the pull cords being exposed. |
