A ski safety binding is designed to allow both a dangerous bending moment exerted about a transverse axis 15 through the weakest point of a skier's leg and a torsional moment exerted about a vertical axis 24 through the skier's leg to be detected and to be used to initiate release of the ski boot 54 from the binding when the bending and/or torsional loads approach dangerous levels. The binding basically consists of a sole plate 11 which carries a boot retaining system 56, 57 and which is mounted on a ski 12 for limited displacement in the longitudinal direction of the ski and for limited pivotal movements about a transverse axis 17 and a vertical axis 24. The sole plate is guided at its rear end for limited movement along an inclined guide 18 and along a transverse guide 21. This movement is resisted by respective hydraulic retaining means 28, 28'; 29, 29' which are however able to resiliently deflect once a predetermined load is exceeded. Movement of the sole plate in the direction of the guides 21, 28 trips a release lever 19 which releases the boot securing system. A mechanical retaining system is also described. |
