ABSTRACT:
A ski mountaineering binding, used for both alpine ski touring and downhill skiing, comprises a subassembly of ski boot binding components used for alpine ski touring, utilizing a hinged flexible touring plate under the sole of a skier's boot, and a subassembly of ski boot safety plate binding components used for downhill skiing. The subassembly of alpine ski touring ski boot binding components during downhill skiing are non flexibly secured from toe to heel, after the flexure interfitting of the rear of the hinged flexible touring plate to a non flexible downhill plate, to which the front of the hinged flexible touring plate is always pivotally secured. During alpine ski touring and downhill skiing the six way safety release functions of the downhill plate safety binding are potentially immediately available. During alpine ski touring a spring force applied at the pivotal securement of the hinged flexible touring plate is stronger at smaller angle positions of the ski boot relative to the ski and becomes weaker at larger angles, thereby making level or near level walking strides easier, yet making hillside side steps more convenient and safe, as the ski at these smaller angles tends to remain closely underneath the ski boot.
