Abstract
A window covering includes a head rail that supports a panel by lift cords such that one end of the panel may be raised and lowered relative to the head rail. An operating system controls movement of the panel and includes spools coupled to the lift cords such that rotation of the spools retracts and extends the lift cords. A shaft is connected to a spool of the lift spool assembly and to a brake and a spring motor. The spring motor applies a motor force to the shaft and the brake applies a brake force to the shaft such that the forces generated by the spring motor and brake hold the panel in the desired position.
