ABSTRACT:
Safety release ski binding. There is here disclosed a release binding for skis in which the force required to effect a release is modulated in response to the relative angular position of the leg of the skier with respect to the longitudinal line of the ski. In the several embodiments shown, a resiliently backed device is provided in the usual manner for releasably holding a ski boot onto a ski, such device effecting release when a predetermined stress is applied for moving the ski boot relative to the ski. A further device is affixed either directly to the leg of the skier or to the upper part of the boot for detecting a longitudinal angular movement of the skier's leg with respect to the ski which device then diminish from a central position, corresponding to a central angular position of the skier's foot or leg, the tension on the above-mentioned resilient holding device. Thus, in a central position, the force required for release is at maximum. As, however, the skier's leg moves toward either a forward or backward limit position, such spring tension is reduced and the force required to effect release is also reduced.
