Abstract (en)

The device has a movable jaw permitting releasing of a shoe i.e. ski shoe, from a snow-sliding board i.e. ski, in case of dangerous stress caused by the shoe during its fixation on the board. A chamber (1) contains magneto-rheological fluid that is subjected to an electromagnetic field generated by an actuator (3) e.g. magnetic field generator such as electromagnet or permanent magnet. Detection units (MD) detect stress. The units transmit a signal (S1) to the actuator. The chamber is parallely mounted with a compression spring.
