ABSTRACT:
A ski brake comprises a symmetrically arranged bearing device comprising a housing on each side of the central ski axis, the housing defining a first bore extending parallel to the central axis, and a bearing bore extending perpendicularly to the central axis. A brake lever is rotatably mounted in the bearing bore, a crank arm extending from one end of the brake lever above the upper ski surface and a brake arm extending from an opposite end at an angle thereto, rotation of the brake lever causing the brake arm to be pivoted from a rest position above the upper surface to a braking position therebelow. A spring is arranged in the first bore for applying an adjusting force to the brake lever to pivot the brake arm into the braking position, an adjustment element is provided having a portion extending into the first bore and having a flange at an end thereof, the spring being arranged between the flange and an end wall of the housing, and a pivot pin extending outside the housing perpendicularly to, and towards, the central axis. A foot pedal is arranged between the adjustment element and the crank arm for transmitting the adjusting force, and the ski brake comprises a damping device exerting a damping force in a direction opposite to the adjusting force of the spring and having a length which is variable along an adjustment path from a rest position in the direction of the damping force, the minimal damping force in the rest position being at least equal to the adjusting force in the braking position of the brake arm.
