Abstract
The present invention is a speed control for a cable retractor. The cable retractor with which the speed control is used comprises a pulley that engages a cable that may be extended and retracted. A friction element configured to adjustably contact the cable adjacent to the pulley is attached to a movable linkage. The movement of the linkage is constrained to move along a predetermined path such that movement of the linkage along the path alters the distance between the friction element and the pulley. In one or more embodiments a cantilevered spring is attached to the linkage. An adjustable control, for example a thumbscrew, is configured to move the spring in relation to the linkage in a manner that alters the position of the friction element with respect to the cable and/or the pressure exerted by the friction element on the cable.
