Abstract: A heel ski boot binding for mounting onto a conventional snow ski is adapted to receive and releasibly maintain the heel of a conventional ski boot during normal skiing operations and to release the boot heel upon application of a predetermined vertical, lateral or torque force through the heel against the heel binding. The heel binding incorporates a biased clamp member that is compressed into a locked attitude against a top edge of the ski boot heel but can be released upon application of a predetermined vertical or torque force. The heel binding also incorporates one or more adjustable biased roller members adapted to be urged against the ski boot heel to secure the heel in position against the ski. The roller members release the ski boot when a predetermined lateral or rotational force is applied through the boot heel to the roller members. The biasing means of the roller members and clamp members are manually adjustable to set the amount of force necessary to overcome the bias and release the ski boot.

Abstract: An adjustable release ski boot binding is provided for holding a ski boot attached to the surface of a snow ski while skiing. The binding is adapted to permit the toe of the ski boot to pivot laterally and/or vertically out of the binding should a predetermined torque force be applied in that direction; as during a fall by a skier utilizing the binding. Individual spring-loaded components of the binding are provided for restricting movement of the ski boot toe in lateral and vertical planes. The compression force of each spring is adjustable to provide different release capabilities for accommodating different skiing styles, and skier weights. In a preferred embodiment, the spring-loaded components for restricting lateral pivoting of the ski boot out of the binding reset automatically after the displacing torque has been removed.
