Abstract
A safety clutch is provided for operating a window treatment having a headrail, a bottomrail and a window covering material extending therebetween. The safety clutch is mounted on a movable frame within the headrail and is moved to rotatably engage the tube lift cord spool on which lift cords are wound and unwound to raise and lower the bottomrail. A brake mechanism connected to the headrail prevents rotating of the tube lift cord spool, and the brake is automatically disengaged upon operation of the safety clutch. A single pull cord is used to operate the safety clutch and the pull cord is maintained in a raised location when not in use.
