ABSTRACT:
A ski brake for bringing a lost ski on a ski slope to a halt, comprises arms which pivot under spring action into an operative position in which a pointed front end of each arm digs into the snow when the ski boot leaves its bindings. Insertion of the ski boot in the binding causes a pedal to be depressed onto the ski and the pedal moves the arms back into an inoperative position almost parallel to the ski. The rear end of each arm is hollow and contains a spring-loaded piston which bears on a cam. In one embodiment the cam is fixed relative to the ski, and the piston and the arm pivot around the cam surface under the action of the spring when the pedal is released. In another embodiment the cam is part of the arm and forms a pivot mounted to rotate in a bearing in a part of the ski. The cam is pivotted by the spring-loaded piston which in this embodiment is slidably mounted in a sleeve fixed relative to the ski.
