RETENUE DE TALON POUR UNE FIXATION DE SECURITE DE SKI

摘要

The invention relates to a heel holder for a safety ski binding, in particular for a safety ski binding for use in both cross-country skiing and downhill skiing. The heel holder has a bearing block fixedly oriented relative to the ski and a housing which carries a sole holder. The housing is supported for an upward pivoting movement about a transversely extending axis provided on the bearing block and against the force of a spring. A spring is arranged in a chamber provided on the housing. One end of the spring is supported on a housing-fixed part and the other end is supported on an adjustable abutment pivotally supported on the bearing block. A two-arm release lever is hingedly connected to the bearing block for effecting a switching between a cross-country mode and a downhill mode of skiing as well as a release of the ski boot from the binding. A control bolt exists on the housing and is guided along a control cam surface arranged on the two upstanding sidewalls of the bearing block.
