ABSTRACT:
A ski brake has a pair of ski elements flanking the ski and each formed by a pair of wires which in the braking position with the ski element projecting down below the bottom of the ski extend at an angle to each other, and which in the rest position extend parallel to the normal displacement direction of the ski and to each other. One of the legs of each of these elements is pivoted about an axis fixed on the ski and the other is pivoted about an axis which can be moved toward and away from the immovable axis on the ski for swinging of the elements up and down between the brake and rest positions. A spring is provided either in the form of a springy joint between the lower ends of the two legs or as a separate compression spring to urge the legs into the brake position. An actuator is displaceable from a raised or advanced position into a depressed position to move the brake elements into the rest position and is similarly urged into the raised or advanced position by the spring.
