Abstract
Abstract A safety ski binding in which the boot is clamped to the ski by the interaction of a ski boot plate and a ski plate; the clamping force is obtained by a rodlike actuating member extending longitudinally in a channel provided in the ski plate and forcing the boot plate rearwardly against complementary engaging surfaces of the ski plate, the complementary engaging surfaces located at a point intermediate the heel and toe of the boot.
