Abstract: A safety binding device for retaining a boot on a gliding board including: a module for detecting the forces to which the boot is subjected, the detection module generating an analog signal proportional to the forces; a decision module integrating a mechanism to convert the analog signal into digital information, and a mechanism to process the digital information according to a release-controlling algorithm depending upon the time and parameters determined by the user's characteristics and/or snow conditions and/or type of sports practice, the processing mechanism generating a control signal; and further including a mechanical actuation module controlled by the control signal and allowing the boot to be released.
