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.
Ski braking device for stopping the free sliding of a ski on snow in case the ski is accidentally or otherwise separated from the ski boot comprising a pivoting braking lever adapted to be brought into frictional contact with, or sunk into, the snow under the force of a spring, said lever being rotatably rigid with a rotary shaft extending across the ski, said rotary shaft being coupled through mechanical means adapted to convert rotation of the shaft into translation of said mechanical means, said mechanical means comprising a toothed pinion rigid with said shaft and a rack portion, said rack portion being movable in the longitudinal direction and responsive to a compression spring reacting against a member substantially fixed in the longidutinal direction.
