Abstract
The present invention is a safety system for use in conjunction with a control bar for a kite wherein the two front lines are secured by a front line swivel positioned between the bar and the kite. One front line terminates at the swivel and one extension of the other front line, the center line, travels through a central aperture in the swivel. The center line is then routed through an aperture on the control bar and terminated with an end that can be secured to the user either manually or by a leash arrangement. The swivel allows any twists that may form in the front lines to unwind. An increased diameter element located proximally of the swivel is configured to engage the center swivel, but is configured to pass through the aperture on the control bar. When the bar is released, sufficient slack is imparted into the remaining flying lines to effectively depower the kite while retaining attachment to the kite through the restrained front line.
