A ski brake includes a length of spring wire of circular cross-section and a holding plate for retaining the brake on the top surface of a ski. The wire has two end portions which are covered with plastic protective caps forming the effective surfaces of the brake. One of the end portions lies on each side of the ski, the brake portions being movable between a position in which they lie essentially in the major plane of the ski and a position in which they extend downwardly below the bottom surface of the ski. A retaining plate is fastened to the top surface of the ski and includes two arcuate recesses which extend transversely across the ski. Between the two end portions, the wire is bent to form a first central shaft portion which extends through one of the arcuate recesses, a second central portion which is U-shaped, and a third central shaft portion which extends through the other arcuate recess. The central portion acts as a spring tending to urge the two end brake portions to their active, downwardly extending position. A small U-shaped bulge permits the central spring portion to clear one of the transverse axis portions to permit the loop to lie flush against the ski surface. Protective caps having longitudinal ribs enclose the end portions to form the active surfaces of the brake.
In a ski brake securable to the upper surface of a ski and having, laterally of the ski, first and second brake spurs which are pivotable about first and second pivot axes, respectively, extending on the upper side of the ski transversely with respect to the longitudinal axis thereof and a holding lever depressible by the ski boot to hold said brake spurs in a rest position, said brake spurs being pivoted into their braking positions by spring action upon removal of a ski boot from the ski binding, the improvement in the brake comprising a wire bent so that one end portion forms a first one of said brake spurs, the other end portion forms the second one of said brake spurs, a first central shaft portion lies in the first one of said pivot axes, a second central portion is shaped into a holding loop forming said holding lever, and a third central shaft portion lies in the second one of said pivot axes, said first and second axes being paarallel and longitudinally spaced apart, said holding loop acting as a spring which moves said spurs to their braking positions and having two positions, one position being against the ski when depressed by the ski boot and the other position being away from the ski when the ski boot is removed from the binding.
