Abstract: An impact absorbing ski binding interface device includes an elongated top plate having a toe end and a heel end adapted to engage a boot toe and a boot heel, respectively, and a bottom plate adapted to engage a ski, thereby securing the device between the boot and ski. A plurality of constant force spring linkages between the top plate and the bottom plate include a constant force spring linkage between the toe end and the bottom plate, and a constant force spring linkage between the heel end and the bottom plate, such that each of the constant force spring linkages have an opposed pair of deformable members for exerting a counterforce to vertical displacement forces between the top plate and the bottom plate for load mitigation.
