Abstract
A window blind assembly is provided. A header mounts near a window. A window blind is moveable between a raised position near the header and a lowered position over a portion of the window. A shaft is rotatably mounted in the header and connected to the blind such that rotation in a first direction raises the blind, and rotation in a second direction lowers the blind. A brake engages the shaft to prevent rotation in the first direction, but allows rotation in the second direction to lower the blind when a downward force is applied to the blind. A brake release is engaged with the brake and is configured such that activation of the brake release releases the brake, allowing the shaft to rotate in the first direction and raise the blind, until deactivation of the brake release causes the brake to reengage the shaft.
