Abstract: A step-in binding for a telemark ski has a safety release mechanism. The binding comprises a mounting plate, a housing, a clamp lever and a step-in lever. Step-in securing is initiated by applying pressure to a step-in lever, which in turn causes a clamp lever to rotate downwardly to hold a ski boot in place. A latching means comprising a tooth and a catching post locks the clamp lever in an engaged position to securely hold the ski boot. A safety release mechanism is activated by rotating the housing assembly about a pivot post such that the tooth falls off the catching post, thus allowing the key to be lowered and opening the toe clamp to release the ski boot. The binding is automatically reset to a position for receiving the ski boot after the safety release mechanism is activated. Preferably, a cable is included within the binding, the cable having a first end which extends around and tightens against the heel of the ski boot and a second end which is raised and lowered as the key is raised and lowered.
