ELECTRONIC SAFETY SKI BINDING WHICH AUTOMATICALLY ADJUSTS ITSELF TO THE CORRECT RELEASE VALUE

摘要

A safety ski binding having force transducers, which derive analog electric signals from vertically acting forces occurring in the ball and heel portions of a skiing boot and from torques acting on the skiing boot. An electronic circuit or a microprocessor is provided having a converter for converting signals from the force transducer into a value which depends on the magnitude and duration of the signals and a comparator circuit for comparing the value with a threshold value which corresponds to permissible stresses. The comparator generates a signal for initiating release of the binding when the threshold value is exceeded. An electric circuit is provided for detecting those of the forces sensed by the force transducers which act in the same sense in a vertical direction during the time for which these forces are acting when no torques are being detected. This circuit detects forces, such as the weight of the skier, if the forces are quasistatic. Another circuit is provided which, in accordance with a predetermined program, sets the release value in dependence on the measured weight of a skier.
