ABSTRACT:
The present invention relates to a ski binding that retains a boot to a ski in at least two independent operational states. One embodiment of a ski binding includes a toe receiving member and a releasable system. The toe receiving member is configured to engage the toe portion of the boot. The releasable system is configured to couple the toe receiving member to the ski in at least two independent operational states. A first state corresponds to a state in which the toe receiving member is allowed to freely rotate with respect to the ski. The first state is particularly useful in minimizing the necessary energy output for uphill travel. A second state corresponds to a state in which the toe receiving member is locked with respect to the ski. The second state is particularly useful in high performance downhill travel. The releasable system further includes an engagement mechanism and a switching mechanism. Additional states may also be included such as a third state in which both the toe receiving member and a heel portion of the boot are fixed with respect to the ski.
