Abstract
A system for incorporation into a retractable covering that includes a flexible lift cord extending from a headrail to a bottom rail. The system includes a flexible protector of a length similar to that of an associated lift cord with the lift cord being operatively connected to the protector. The protector is in turn connected to a fabric extending between the headrail and the bottom rail at predetermined spaced locations so that any loop of protector formable is limited by the spacing between the locations at which the protector is connected to the fabric. The maximum size of a loop so formed in the protector and thus the lift cord associated therewith is insufficient to encapsulate a body part of a child or infant.
