Abstract: Safety ski binding for use in both downhill and cross-country skiing. A conventional 3-pin 75 mm. toe binding is mounted on a front base plate which is rotatable during downhill skiing, but is locked against rotation for cross-country skiing. The rear binding assembly employs a reversed Cubco toe binding used as a heel binding, which is locked to a heel latch assembly during downhill skiing, the heel latch being unlocked during cross-country skiing. In downhill skiing a safety release occurs by overcoming the spring compression of the Cubco binding, and such release is facilitated by the rotation of the ski boot about the axis of the front base plate. During cross-country skiing the heel latch is unlocked, and the heel of the ski boot is free to move vertically above the ski.
