Ski safety binding

Claim 1

A ski safety binding for ski boots comprising, a foot-plate for mounting on the upper surface of a ski, spaced front and rear end stops fixed to said ski upper surface and between which said binding is mounted, at least one of said stops including a flexible retaining device, said foot-plate including clamping members for a boot, at least one of said clamping members being adjustable so as to enable the attachment to said ski of a boot of shorter or longer length than the length of said foot-plate, the upper surface of said rear stop disposed substantially flush with the upper surface of said foot-plate to enable one of the ends of a boot longer than the foot-plate to extend beyond it, and a planar extension plate mounted on the rear of said footplate and extending the upper surface of the rear end of said foot-plate beyond the rear of said foot-plate and in an overlying manner relative to said rear stop, said extension plate engaging the upper surface of said rear stop and supporting at least a portion of the bottom surface of a heel of a boot to provide a continuous boot supporting member having a substantially planar supporting surface from the toe to the heel of the boot, said extension plate having a low coefficient of friction relative to said rear stop to facilitate separation as an integral unit of said foot-plate extension plate and boot from said ski upon impact of an unusual force.
