Abstract

Heel tensioner for ski safety bindings, with an advance member for the ski boat, arranged substantially between the branches of a u or V-shaped retention motion, which supports it in a pivotable manner about an axis transverse to the longitudinal axis of the ski and parallel to the support surface of the ski, the free ends of the branches serving as guides for the traction organs, with which the tensioner is subject to skiing and which, under the intercalation of at least, a spring acts on the advancing member, providing the spring, or the springs, both the force for holding the heel, as well as the tightening against a retaining device for the tip of the ski boat, and having a safety coupling is provided between the advancing member and the retaining frame, by means of which, acting the heel tensioner arranged to run with the ski, prevents a rotation of both parts relative to each other eg however, they uncouple two parts when an excessive load is actuated, characterized in that said advancing member extends backwards beyond its articulation axis in the retaining frame and forms a two-armed lever, whose arm extended forward can to be brought into contact by its free end, with the heel of the boot, while its other arm forms, in the longitudinal direction of the guide lever, a guide for a sliding part, to which the traction members are coupled; because each of the springs presses the sliding part with one of its ends, while with its other end it rests against a fixed part of the advancing member, and because as a coupling part provided in the advancing member, it serves a the spigot supported on the sliding part, while a locking member, which can be released at will, serves as the coupling part provided in the retaining frame.
