ABSTRACT:
A ski brake has a pair of elongated braking elements which extend parallel to each other and are pivoted about their middle portions about a pivot axis extending parallel to the upper surface and transverse to the longitudinal direction of a ski so that these braking elements can pivot between a rest position parallel to the ski and a braking position transverse to the ski and digging into the snow under the ski. An actuating member or plate is displaceable toward and away from the upper surface of the ski and is linked to the upper ends of the braking elements so that its displacement toward the surface of the ski will swing the elements into the rest position. In addition this actuating member is provided with links which tend to swing the lower ends of the braking elements inwardly above the surface of the ski so that they do not project laterally from the ski during use thereof. A pivot spring normally urges the elements into the braking position and another spring urges them into the retracted position above the upper ski surface.
