<p>A heel piece for a safety ski binding is provided comprising a support member in the form of a slide member on which is pivotally mounted a sole holder having a pedal, a sole engaging portion and an interior cam surface configured to cooperate with a bearing member or cam follower which engages the cam surface. The cam follower is supported by a bearing lever having an axis of rotation near the upper surface of the ski, and a connecting member. The cam surface has an upper portion, a lower portion and an intermediate critical portion, and the binding opens when the soleholder is driven upwardly so that the critical portion passes the cam follower. An opening lever for manually opening the binding is rotatably attached to the connecting member, and is pivotally mounted on the soleholder. A spring disposed between the axes of the opening lever and of the bearing lever biases the connecting member to urge the soleholder to a closed position when the cam follower is in the upper cam portion, and to an open position when the cam follower is in the lower cam portion.</p> |
