Antifriction bearing device for ski safety binding

摘要

The antifriction bearing device for a safety binding (2) of a ski (1) is arranged in the front zone of the boot (3) between the sole of the latter and the ski (1). It comprises an antifriction small plate (4) attached to a support plate (5) and arranged so that the plane of the lower face of the sole of the boot (3) in position and the plane of the upper face of the small plate (4) in the bearing zone form an acute angle ( alpha ) which opens up towards the rear and so that the support plate (5) has at least one ramp (6) inclined rearwards, running as far as the upper face of the ski (1), the small plate (4) covering this ramp (6) also as far as the ski (1).
