Binding system

1. A binding configured to releasably couple a boot to a ski comprising:

a toe receiving member configured to engage a toe portion of the boot;

a releasable system configured to couple the toe receiving member to the ski in at least two independent operational states, wherein a first state corresponds to a state in which the toe receiving member is free to rotate with respect to the ski, and wherein a second state corresponds to a state in which the toe receiving member is locked with respect to the ski, and wherein the releasable system further comprises:

a switching mechanism configured to transition the releasable mechanism between the first and second state; and

an engagement mechanism configured to engage the toe receiving member in the second state, wherein the engagement mechanism is an under-boot rotatational latching mechanism, and wherein the axis of rotation of the latching mechanism is substantially parallel to the ski.

2. The binding of claim 1 further includes a selectively engaged heel retention system to provide a third state in which both the toe receiving member and a heel portion of the boot are fixed with respect to the ski.

3. The binding of claim 1 , wherein the releasable system further includes a rotation point about which the toe receiving member is able to rotate with respect to the ski in the first state.

4. The binding of claim 3 , wherein the toe receiving member includes a pivot point about which a boot is able to pivot with respect to the ski in the second state, wherein the pivot point is disposed at least 30 mm away from the rotation point.

5. The binding of claim 1 , wherein the toe receiving member includes a pivot point about which a boot is able to pivot with respect to the ski in the second state, wherein the pivot point is disposed at least 24 mm away from the front of the boot.

6. The binding of claim 1 further including a heel attachment system configured to couple between the toe receiving member and a heel portion of the boot, wherein the heel attachment system includes a replaceable pivot biasing system.

7. The binding of claim 1 further including a heel attachment system configured to couple between the toe receiving member and a heel portion of the boot, wherein the heel attachment system includes a heel throw and at least one under-boot cable.

8. The binding of claim 1 , wherein the switching mechanism is configured to require a pushing force to transition between the first and second state and between the second and first state.

9. The binding of claim 1 , wherein the engagement mechanism is spring-biased toward an engaged position.

10. The binding of claim 1 , wherein the engagement mechanism is configured to automatically engage the second state if operation of the releasable mechanism is compromised in any manner.

11. A binding configured to releasably couple a boot to a ski comprising:

a toe receiving member configured to engage a toe portion of the boot;

a releasable system configured to couple the toe receiving member to the ski in at least two independent operational states, wherein a first state corresponds to a state in which the toe receiving member is free to rotate with respect to the ski, and wherein a second state corresponds to a state in which the toe receiving member is locked with respect to the ski, and wherein the releasable system further comprises:

a switching mechanism configured to transition the releasable mechanism between the first and second state; and

an engagement mechanism configured to engage the toe receiving member in the second state, wherein the engagement mechanism is a spring-biased under-boot latching mechanism.

12. The binding of claim 11 further includes a selectively engaged heel retention system to provide a third state in which both the toe receiving member and a heel portion of the boot are fixed with respect to the ski.

13. The binding of claim 11 , wherein the spring-biased latching mechanism is spring-biased toward an engaged position.

14. The binding of claim 11 , wherein the toe receiving member includes a pivot point about which a boot is able to pivot with respect to the ski in the second state, wherein the pivot point is disposed at least 24 mm away from the front of the boot.

15. The binding of claim 11 further including a heel attachment system configured to couple between the toe receiving member and a heel portion of the boot, wherein the heel attachment system includes a replaceable pivot biasing system.

16. The binding of claim 11 , wherein the switching mechanism is configured to require a pushing force to transition between the first and second state and between the second and first state.

17. The binding of claim 11 , wherein the engagement mechanism is configured to automatically engage the second state if operation of the releasable mechanism is compromised in any manner.

18. A binding configured to releasably couple a boot to the ski comprising:

a toe receiving member configured to engage a toe portion of the boot;

a releasable system configured to couple the toe receiving member to the ski in at least two independent operational states, wherein a first state corresponds to a state in which the toe receiving member is free to rotate with respect to the ski, and wherein a second state corresponds to a state in which the toe receiving member is locked with respect to the ski, and wherein the releasable system further comprises:

a switching mechanism configured to transition the releasable mechanism between the first and second state; and

an engagement mechanism configured to engage the toe receiving member in the second state, wherein the engagement mechanism is configured to automatically engage the second state if operation of the releasable mechanism is compromised in any manner.

19. The binding of claim 17 , wherein the engagement mechanism is an under-boot rotatational latching mechanism, wherein the axis of rotation is substantially parallel to the ski.

20. A method for automatically engaging a locked state on a multiple operational state ski binding comprising the acts of:

providing a ski binding which releasably engages a toe portion of a boot to a ski in at least two independent operational states, wherein the binding includes a first state in which the boot is free to rotate with respect to the ski, and a second state in which a portion of the boot is substantially fixed with respect to the ski;

causing an operational failure of the ski binding in which the binding is no longer capable of switching between the independent operational states; and

automatically engaging the second state of the ski system to substantially fix a portion of the boot with respect to the ski.
