Abstract
The safety ski binding is primarily intended to retain the toe end of a ski boot and comprises a yoke pivotally mounted on a cross-pin in a stationary hollow body. The jaw unit for retaining the ski boot is guided in longitudinal sliding motion within the yoke. The jaw unit is provided with semi-cylindrical grooves directed towards the ski boot and having the function of cooperating with support rods attached to the yoke. The jaw unit is also associated with a cylindrical roller which is directed away from the ski boot and is intended to cooperate with a locking lever. The ski binding provides compensation for the parasitic friction forces which arise from complex falling movements involving forward-fall and twisting motion as well as backward-fall and twisting motion.
