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.

A safety ski-binding releasable from a latched condition in response to the occurrence of an external force exceeding a predetermined force setting of the binding, said binding comprising sole plate means mountable on a ski for pivotable movement about an axis perpendicular to the surface of the ski; tongue means operatively associated with said sole plate means and with said base plate means, said tongue means having a lower surface with configuration of the letter W; lower support means fixable on the ski opposite the W-shaped lower surface of said tongue means, said lower support means being engageable with the tips of said W in the absence of a sideways load on the binding; and said W-shaped lower surface being inclined to engage said lower support means upon the occurrence of a downward and sideways load to compensate for the effect of friction on said internal force.
