ABSTRACT:
An acceleration compensated step-in type ski binding for releasably securing a ski boot to a ski. The ski binding includes a pivotable body member mounted on a support plate attached to the ski which engages the boot on one side of a pivot and carries a mass on the opposite side of the pivot. The mass generates a moment equal and opposite to the moment generated by the acceleration of the boot so as to cancel out the internal forces resulting from such acceleration of the boot. The ski binding further includes a boot engagement assembly for engaging a first portion of the ski boot. The boot engagement assembly is further coupled to the support plate so as to be prevented from rotating under the influence of external forces acting on the bindings such that the boot engagement assembly translates across the ski and the fulcrum length between the contact point of the boot and the boot engagement assembly remains constant to insure the proper functioning of the acceleration compensating part of the ski binding despite the wide variety of positions at which the ski boot can engage the binding.
