Abstract
A front jaw for a ski binding having a base plate fixedly secured to the ski and on which two pivot axes are positioned which are perpendicular with respect thereto. A two-arm lever is pivotally supported on each of the pivot axes and one arm thereof is adapted to move into and out of engagement with the toe of the ski boot. The other arm of each two-arm lever cooperates with a pull rod resiliently urged to the initial position by an adjustable spring operated mechanism to resiliently hold the toe of the ski boot in the clamped position on the ski. Each of the two-arm levers cooperates with an intermediate structure to effectively control the spring force urging the two-arm levers to the clamping position holding the ski boot onto the ski. In one embodiment, this intermediate structure is a plate resiliently held perpendicular to the longitudinal axis of the pull rod and is moved to a position out of perpendicular relationship against the spring force by a pivoting of one of the two-arm levers. Another embodiment includes a guide for effecting a movement of the plate while maintaining the perpendicular relationship with the axis of the pull rod. A still further embodiment utilizes …
