Ski binding suspension system for vertical load transmission

A method for mitigating force between a ski boot and a ski, comprising:

• receiving a vertical force imposed from a ski towards a boot;
• drawing a near constant force member around a rigid member in response to the vertical force;
• and
• deforming a segment of the near constant force member in an elastic field from a curved orientation around the rigid member towards a straight orientation based on the vertical force.

An impact absorbing ski binding interface device, comprising:

• an elongated top plate having a toe end and a heel end and adapted to engage a boot toe and a boot heel, respectively;
• a bottom plate adapted to engage a ski;
• a plurality of near constant force spring linkages between the top plate and the bottom plate, further comprising:
• a near constant force spring linkage between the toe end and the bottom plate;
• and
• a near constant force spring linkage between the heel end and the bottom plate, each of the constant force spring linkages having at least one deformable member for exerting a counterforce to vertical displacement forces between the top plate and the bottom plate.
