An electrically releasable safety ski binding in which a measuring system determines the load applied to a skier\s leg during skiing and a release mechanism incorporating an electromechanical converter such as a solenoid acts on a clamp device securing the ski boot to the binding to release the ski boot when the aforementioned load reaches a dangerous level. To prevent the binding becoming inoperative on failure of the electrical power supply the binding is equipped with an auxiliary release mechanism having a first inoperative state and a second operative state which can be selected either manually or automatically should the electrically operated release mechanism fail.

An electrically releasable safety ski binding comprising a fixed binding part; retaining means for releasably retaining a ski boot in the binding; a battery operated power supply; electrical measuring sensor means for sensing the load on a skier\s leg; a signal former connected to said electrical measuring sensor means for forming a release signal when said load reaches a predetermined value; a release mechanism including an electromagnetic converter, wherein said electromagnetic converter is responsive to said release signal to release said retaining means for movement away from said ski boot; a normally inoperative release spring associated with said release mechanism, said release spring having first and second ends; and means for placing said release spring in an operative state on failure of said power supply; wherein, in said operative state, said release spring is disposed operatively in parallel with said electromagnetic converter, with said first end being braced against a fixed housing part and said second end bearing on said release mechanism; and wherein said release spring is arranged to yield in said operative state to permit release of said binding once a predetermined release setting is reached.
