Safety ski-binding having a sole plate

摘要

A safety ski-binding having force transmitting surfaces which are inclined at an angle which corresponds substantially to the angle of friction. The force component acting in the direction of release of the sole plate created by the additional load compensates for the friction, so that the release resistance is not influenced even for a heavy load from the ball of the skier's foot even for the purely rotary fall load. These inclined surfaces are preferably provided on a rearward tongue which is disposed between the base plate and a rearward guide rail, the rearward tongue comprising an upper surface in substance in the shape of a flat M whose upper tips are flattened to abut in the normal position supporting elements depending from the guide rail. A forward tongue and guide rail is similarly provided and both the forward and/or rearward tongues which are configured at their lower and upper surfaces, respectively, as a W or an M, for engaging two supporting elements on a ski structure cooperating with the respective tongues for compensating for friction on the binding.
