ABSTRACT:
In the heel area of a ski boot a rubber torsion spring element is arranged, the core piece of which is anchored in a rotationally fixed manner on the lower shell of the ski boot by means of a bracket. An outer tubular piece, which surrounds the core piece coaxially, is connected to a tension member which engages with its end at the rear on a rear shaft part of the boot shell. The rear shaft part and a front shaft part are pivotable relative to the lower shell about an articulation axis into a forward lean position. The spring element damps the forward lean movement and, by means of the use of snappy rubber compounds, is extensively independent of the ambient temperature. Additionally, it allows the adjustment at least of the starting point of the spring or damping effect by means of a knurled nut.
