Abstract
Abstract A ski binding having a portion which holds the ski boot and moves relative to a ski over a predetermined distance and in predetermined directions, which may be perpendicular to each other, relative to the ski. The binding employs a mechanical or electromechanical transducer for sensing the skier's movement which triggers a relative movement of the binding. Guides are provided to direct and limit the movement of the binding. A power activator for the binding is generally disposed between the sole of the ski boot and the ski and utilizes relatively minor movements of the ski boot sole, or electrical power, to move the binding portion relative to the ski.
