Variable-height device for supporting a boot on a ski

摘要

A supporting device which is adjustable for height in order to adapt ski bindings to the thickness of ski-boot soles comprises a control member guided for longitudinal sliding motion within a stationarily fixed base plate. The control member cooperates with a support plate by means of stair-step surfaces having inclined risers. The longitudinal displacement of the control member produces a vertical displacement of the support plate by wedge effect.
