Freely slidable antifriction plate which automatically recenters for

Abstract

A safety binding for binding a boot to a ski, which includes first and second laterally pivotable independent wings adapted to retain one end of the boot on the ski. Each of the wings is mounted to pivot around respective first and second lateral pivot axes. Elastic return means bias each of the wings towards a centered stable maintenance position of the boot. The apparatus includes a movable antifriction plate adapted to slide laterally in a sliding zone of the upper surface of the ski. An intermediate linkage assembly is provided for associating the antifriction plate with the binding wings. The intermediate linkage assembly is adapted whereby lateral pivoting of either of the wings permits rearward movement of the linkage assembly whereas return of either of the wings to the centered position assures the return of the intermediate linkage assembly towards its front longitudinal extreme position. The intermediate linkage assembly is linked with the antifriction plate in a manner so as to permit free lateral movement of the antifriction plate between two extreme positions. The spacing between the extreme positions of the antifriction plate is proporational to the extent of displacement of the intermediate linkage assembly, and return of the intermediate linkage assembly towards its front longitudinal extreme position tends to recenter the antifriction plate.
