Ski or skate binding
A binding for a vehicle, such as a skate for skating on ice or a ski. The binding has an upper chassis section and a lower chassis section, which are interconnected by means of coupling means. The upper chassis section and the lower chassis section are arranged to be rollable relative to each other in the vehicle's longitudinal direction. The binding includes a first and a second contact surface at least one of the first and the second contact surface being curved. Thereby a stepless rolling motion between the upper chassis and the lower chassis is provided for, allowing the chassis to rock both backwards and forwards in relation to each other.

an upper chassis section;
a lower chassis section; and
a coupler,
wherein the upper chassis section and the lower chassis section are engaged via the coupler, and are pivotally arranged relative to each other in the longitudinal direction of the vehicle,
wherein the upper chassis section is pivotable at least in a backwards direction in relation to a neutral position of the upper chassis section and the lower chassis section,
wherein the binding further includes a first contact surface and a second contact surface,
wherein at least one of the first contact surface and the second contact surface is curved, and
wherein the first contact surface and the second contact surface are arranged such that, during pivoting of said upper chassis section in the backwards direction, said first and second contact surfaces roll against each other providing a rolling motion between the upper chassis section and the lower chassis section in said backward direction.

3. The binding in accordance with claim 2 , wherein the coupler further includes at least one bushing.
4. The binding in accordance with claim 2 , wherein the coupler is arranged essentially horizontally in the transverse direction of the binding.
5. The binding in accordance with claim 2 , wherein at least one of the lower chassis section and the coupler is integrated with a vehicle.
6. The binding in accordance with claim 3 , wherein said bushing consists of one of at least one spring and an elastic material.
7. The binding in accordance with claim 1 , wherein the coupler includes at least one strap.
8. The binding in accordance with claim 1 , wherein at least one of the first contact surface and the second contact surface is interchangeable.
9. The binding in accordance with claim 8 , wherein at least one interchangeable contact surface includes a separate front portion and a separate rear portion.
10. The binding in accordance with claim 1 , wherein the coupler is arranged essentially horizontally in the transverse direction of the binding.
11. The binding in accordance with claim 1 , wherein the coupler is arranged essentially vertically in the binding.
12. The binding in accordance with claim 1 , wherein the binding is arranged to be mounted on top of or below a clap binding.
13. The binding in accordance with claim 1 , wherein at least one of the upper chassis section and the coupler is integrated with a shoe.
14. The binding in accordance with claim 1 , wherein at least one of the lower chassis section and the coupler is integrated with a vehicle.
15. The binding in accordance with claim 1 , wherein said first contact surface is included in the upper chassis section.
16. The binding in accordance with claim 1 , wherein said second contact surface is included in the lower chassis section.
17. A binding for a vehicle, such as a skate for skating on ice or a ski, comprising:
an upper chassis section;
a lower chassis section; and
a coupler,
wherein the upper chassis section and the lower chassis section are engaged via the coupler, and are pivotally arranged relative to each other in the longitudinal direction of the vehicle,
wherein the binding further includes a first contact surface and a second contact surface,
wherein at least one of the first contact surface and the second contact surface is curved, wherein the first contact surface and the second contact surface are arranged such that, during pivoting of said upper chassis section and said lower chassis section relative to each other, at least a portion of said first contact surface is in contact with at least a portion of said second contact surface,
wherein at least one of the first contact surface and the second contact surface is interchangeable, and
wherein at least one interchangeable contact surface is movable in relation to one of the upper chassis section and the lower chassis section in the longitudinal direction of the vehicle.
18. A binding for a vehicle, such as a skate for skating on ice or a ski, comprising:
an upper chassis section;
a lower chassis section; and
a coupler,
wherein the upper chassis section and the lower chassis section are engaged via the coupler, and are pivotally arranged relative to each other in the longitudinal direction of the vehicle,
wherein the binding further includes a first contact surface and a second contact surface,
wherein at least one of the first contact surface and the second contact surface is curved, and wherein the first contact surface and the second contact surface are arranged such that, during pivoting of said upper chassis section and said lower chassis section relative to each other, at least a portion of said first contact surface is in contact with at least a portion of said second contact surface, and
wherein the binding further includes a separate intermediate element arranged between the upper chassis section and the lower chassis section, which intermediate element includes an upper contact surface, which constitutes a further second contact surface, and a lower contact surface, which constitutes a further first contact surface, wherein at least one of said upper and lower contact surfaces is curved.
19. A ski, a skate for skating on ice, or shoe comprising:
a binding, the binding including,
an upper chassis section,
a lower chassis section, and
a coupler,
wherein the upper chassis section and the lower chassis section are engaged via the coupler, and are pivotally arranged relative to each other in the longitudinal direction of the vehicle,
wherein the upper chassis section is pivotable at least in a backwards direction in relation to a neutral position of the upper chassis section and the lower chassis section,
wherein the binding further includes a first contact surface and a second contact surface, wherein at least one of the first contact surface and the second contact surface is curved, and
wherein the first contact surface and the second contact surface are arranged such that, during pivoting of said upper chassis section in the backwards direction, said first and second contact surfaces roll against each other providing a rolling motion between the upper chassis section and the lower chassis section in said backward direction.
