In safety ski bindings with electronic evaluation and release circuits, which can be supplied from a voltage source through a switching device and which activate, in case of risk of injury, a release mechanism for the release of a ski boot held in the binding, there exists the problem that the control circuit is supplied with voltage even when the skier stands still with attached skis or travels on a chairlift, which results in an unnecessary current consumption. To solve this problem, a selectively activatable acceleration responsive device is provided in the switching device, which acceleration responsive device is connected to an electronic switching element through a time circuit and, if desired, through a threshold switch.

A safety ski binding adapted to be mounted on a ski, comprising: electrically actuated release means for releasably holding a ski boot on the ski; sensor means for producing electrical signals in response to forces acting on a ski boot releasably held by said release means; control circuit means operatively coupled to said release means and said sensor means and adapted to evaluate said signals from said sensor means for selectively causing said release means to release a ski boot held therein if said signals from said sensor means indicate forces in excess of a predetermined value are acting on the ski boot; an electrical power source; acceleration responsive means which produces an output signal when an acceleration force in excess of a predetermined value acts on said binding; and time circuit means responsive to said acceleration responsive means for supplying electrical operating power from said power source to said control circuit means for a predetermined interval of time in response to said output signal from said acceleration responsive means and for automatically interrupting the supply of electrical power from said power source to said control circuit means at the end of said predetermined interval of time, wherein electrical power is supplied by said time circuit means to said control circuit means only for said predetermined interval of time in response to each said output signal from said acceleration responsive means.
