Abstract
A cordless blind having a mechanism for introducing a variable amount of friction into the operation of the cordless blind is disclosed. The cordless blind includes a spring motor operatively connected to a cord connected to the window covering of the blind. Pulling and releasing the cord expands and retracts the blind. In order to introduce additional resistance to movement into the system when retracting the blind and not when expanding the blind, variable friction mechanisms or retarders, including one-way bearings, and one-way braking arms, are used for introducing friction into the system only when desired.
