ABSTRACT:
This invention is an improvement over the structure illustrated in U.S. Pat. No. 3,902,730. The ski binding includes a pair of pivoted sole holders pivotal about axles which are fixed to the ski. The sole holders each have two arms, one of which engages the ski boot adjacent the toe thereof and the other arm engaging a structural part which is under spring tension, which spring tension must be overcome in order to effect a release of the ski boot from the ski. Structure is provided to interrupt the transfer of force of the ski boot acting on the spring intermediate the travel of the particular sole holder so that a decrease in the force resisting movement of the ski boot occurs and the ski boot can be freely removed from engagement with the ski.
