VORRICHTUNG ZUR SEITLICHEN FUEHRUNG UND ABSTUETZUNG EINES SKISTIEFELS

摘要

A lateral guidance and support apparatus for a ski boot attached, at its front end, to a cross-country ski, whose heel is free to be displaced at least vertically with respect to the ski. The apparatus includes a longitudinally extending retention rib positioned at the upper surface of the ski which is adapted to engage a longitudinally extending groove in the sole of the boot having substantially the same cross-sectional configuration as the rib. The groove progressively covers the rib when the boot is flattening on the ski. Also provided are one or more projections extending laterally from the rib. These projections are positioned under a support zone of the boot when the boot is attached to the binding and when the grooves in the boot engage the rib on the ski. The support zone of the boot is that portion of the boot positioned under the metatarsus of the foot or positioned under a region of the foot in front of the metatarses. As a result of this structure the rib guides the boot from the beginning of the gait of the foot, thereby increasing the precision and effectiveness of cross-country skiing.
