Abstract: A releasable safety ski binding holding a release plate, having a safety release device secured to the ski for releasably holding the release plate to the ski. A heel holder is longitudinally non-adjustably mounted on the rear of the release plate, and a toe holder is adjustably disposed on the front of the release plate to hold different size ski boots without affecting the safety release holding of the binding. In another embodiment, the safety ski binding has a lateral and vertical safety release member only adjacent one end of the release plate, the other end of the release plate defining a vertical release pivot fulcrum. The release plate is pivotally mounted on the ski intermediate its ends, whereby different lateral and vertical release moments exist.
