  • Patent number: 4494769
    Abstract: The toe abutment member of a ski binding is adapted to cooperate with a ski boot provided with a sole having a truncated front end and a toe-cap extension in overhung relation to the truncated front end. The abutment member comprises a feeler element placed directly beneath the toe-cap extension of the ski boot in close proximity to the toe-cap extension under normal skiing conditions. In the event of a forward fall, the feeler element undergoes a vertical displacement in the downward direction under the thrust exerted by said extension while producing a reduction in inherent stiffness of release of the toe abutment member.
