ABSTRACT:
A method and apparatus for actuating a safety ski binding, for the purpose, in hazardous situations, of automatically releasing a ski boot from a ski on which it is held. The forces exerted by the ski on the leg of the skier are continuously integrated with respect to time. The thus formed time integral of the force releases the connection between the ski and boot on reaching a threshold value representing a product of force.times. time which is higher than the integration threshold value corresponding to the holding force of the ski binding. To avoid a summation of pulses, a pulse that has not resulted in actuation is cleared through downward integration.
