ABSTRACT:
Under normal skiing conditions, two lateral arms of a jaw unit cooperate with the toe end of a ski boot in order to maintain the boot in the axis of the ski and are held in position with a force designated as the inherent stiffness of release. When an excessive twisting effort is exerted on the skier's leg, the arms both move in a transverse direction with respect to the ski in order to permit lateral disengagement of the boot. A toe abutment feeler member is in contact with the front end of the boot and cooperates with a spring-loaded piston unit in order to reduce the inherent stiffness of release as well as resistance to torsional disengagement in the event of a forward fall of the skier and/or of an axial thrust exerted by the boot, thus achieving considerably enhanced safety.
