Abstract
A safety ski binding includes a holding jaw and a jaw which can be released electrically under control of a control circuit. The holding jaw includes two movable sole holders having thereon pistons movable in respective, fluid-filled chambers. The holding jaw also includes a movable stepping plate, and the stepping plate and one sole holder can each flex respective membranes of a further fluid-filled chamber. Each of the three chambers communicates with a respective piezoelectric element which is connected to the control circuit. Forces applied to the holding jaw by a ski boot can increase the pressure in the various chambers and the piezoelectric elements each produce a signal proportional to such pressure, the control circuit electrically releasing the other jaw if the forces exceed predetermined values.
