ABSTRACT:
A ski braking device adapted to be preset automatically by fitting the ski boot to the ski. It comprises essentially a pair of braking arms having a common transverse shaft. These arms are normally parallel to the top surface of the ski and their shaft is rigid with a crank arm pivoted to a longitudinally movable member associated with spring means and adapted to transform the movement of rotation of said shaft into a movement of translation of said longitudinally movable member against the resistance of a spring. This arrangement constitutes a knee action mechanism and the device can operate efficiently whether the ski is sliding downhill with the ski tip or the heel end first. Means for locking the device against operation for transport or other purposes are provided.
