ABSTRACT:
A safety ski binding has a toe unit arranged in front of a front foot plate (21) and a heel unit which exerts a forwardly directed thrust force on the toe unit via the inserted ski boot. The toe unit has a sole clamp (16) which supports the front part of the sole (14) of the ski boot (15) from the front, sideways and from above and is pivotable against a substantially forwardly directed spring force about a respective one of two substantially vertical axes of rotation (17) provided on both sides of the vertical central longitudinal plane (11). An abutment (18) which faces downwardly and forwardly is provided on the sole clamp (16) at the region between the axes of rotation (17) and cooperates with an inclined surface (19) which is fixed relative to the housing and which extends downwardly and rearwardly from the top. The cooperation between abutment (18) and surface (19) is such that when the ski boot (15) is inserted its sole (14) holds the sole clamp (16) against the downwardly directed spring bias at a level at which the abutment (18) is located at at least a small distance from the inclined surface (19). The ski boot (15) is downwardly yieldingly supported on the ski (22) whereby a downwardly directed counterforce to the sole clamp resetting force is generated during a forward fall in dependence on the inclination of the inclined surface (19) and on the resilient bias of the sole clamp (16).
