ABSTRACT:
A safety ski binding for securing a ski boot to a ski having a medium plane extending longitudinally along the center of the ski and perpendicular to the ski comprises a toe boot element on the toe of the ski boot, a heel boot element on the heel of the ski boot, respective toe and heel ski elements secured to the ski at the median plane thereof and lockingly engageable with the toe and heel boot elements, and means for urging one of ski elements along the plane towards the other ski element. One of the toe elements comprises a pair of generally cylindrical and parallel pins flanking the median plane and the other one of the heel elements is a generally cylindrical body lying substantially perpendicular to the plane and formed at the plane with a circumferencial groove and the other heel element is a profiled button lying on said plane and engageable in the groove. The means for urging comprises a piston displaceable along the ski relative to an abutment by a spring braced between the abutment and the piston. The toe and heel elements may be carried on a separate sole plate releasably secured to the bottom of the ski boot, and the toe ski element may be carried on a pivotal support so as to allow the skier readily to release the ski boot from the ski. The spring is biased against the heel ski element so that when the boot is twisted or the toe of the boot is lifted this boot is displaced backwardly against the spring force allowing the toe to free itself from the binding. When the heel of the boot is lifted the grooved cylindrical body compresses the spring and allows the heel to pull free from the heel ski element.
