Apparatus for adjusting a safety ski binding

Apparatus for adjusting a safety ski binding, comprising:

• a support with means for rigidly fixing a ski to said support.
• A foot-simulating device intended to be introduced and fixed in a ski boot mounted in a ski binding which belongs to said ski, said device including an upright,
• means for applying stress to said upright according to a plurality of different stress modes, said means for applying stress to said upright comprising:
• an elongated stress-transmission element having a first end integral with said upright, a second end formed as a coupling part and a central portion between said ends, arranged for undergoing resilient deformations as a function of said stresses applied to said upright;
• and
• a stress creating means connectable to said coupling part according to a plurality of different ways for imparting stresses to said upright in different ranges corresponding to said different stress modes, said stresses imparting to said central portion, in each of said stress modes, resilient deformations in a corresponding range of deformations;
• and said apparatus further comprising measuring means including means for commutation between a plurality of functioning modes, each of which corresponds to another one of said stress modes, and able in each functioning mode to provide information on the stresses applied to the upright, said information being responsive to measurements by said measuring means of the deformations imparted to said central portion in the corresponding stress mode.
