Abstract
The present disclosure is directed to a novel heavy duty, weather and shock resistant retractable lanyard. In one aspect of the disclosure, the retractable lanyard comprises dual independently retractable lanyard cords that share a common axis. In another aspect of the disclosure, the retractable lanyard employs a multi-piece reader arm pivotally connected to a reader arm bracket to assist the lanyard in operating under heavier loads. In another aspect of the disclosure, the lanyard may employ deeper tracks on the spool's track system to allow the reader arm to stay in contact with the tracks when the lanyard cord is under heavier loads. In another aspect of the disclosure, the lanyard comprises a robust power spring that allows it to retract under heavier loads.
