  • Patent number: 4358132
    Abstract: A safety ski binding includes an end piece engageable with a ski boot and horizontally pivotable on a body rotatably mounted on a pivot member carried on the surface of a ski for vertical pivotability with respect to the ski. The vertical pivot member includes two diametrically opposed cam faces movable in the longitudinal direction of the ski, each of the cam faces being engaged by a separate piston while being urged by a common spring. The end piece is adapted to move one of the two pistons away from the corresponding cam surface on vertical movement of the end piece. A modified embodiment of the invention utilizes a single piston and the spring controls the release of the ski boot under both side torsion stresses and vertical movements of the ski boot end associated with the binding when they exceed predetermined and adjustable limit values.
