Abstract:
1. A ski binding device for fastening a mountaineering boot on a downhill ski comprising: a toepiece and a heelpiece which are adapted to be rigidly fixed on the back of a ski, aligned along a ski longitudinal axis (L), and are structured so as to selectively retain respectively a front part and a rear part of a shell of a boot; the toepiece being provided with a clamping member which is structured so to selectively clamp and stably retain the front part of the shell, and at the same time allow the shell to pivot freely on the toepiece about a boot rotation axis (A) substantially perpendicular to the ski longitudinal axis; the heelpiece comprising a fastening base structured for being rigidly fastened on the back of the ski; a turret protruding upwards from the fastening base; and a hooking projecting appendix that juts out from the turret towards the toepiece while remaining substantially parallel to a first reference axis (C) substantially aligned to the ski longitudinal axis (L), and is structured so as to couple to the rear part of the shell to stably retain the heel of the ski boot in abutment on or close to the back of the ski, therefore preventing any rotation of the boot on the toepiece about said boot rotation axis; the binding device being characterized in that the heelpiece comprises a latch element which extends through the body of the turret remaining substantially parallel to said first reference axis (C), with the possibility of moving forwards and backwards with respect to the turret parallelly to said first axis (C); the hooking projecting appendix being formed by the tip of said latch element, and the heelpiece also comprising a manually-operated command device, which is structured so as to displace the latch element forwards and backwards on the turret, and stably lock said latch element
