<p>The heel piece (1) is constituted by a base (2) fixed to the ski (S) and by an upper block (4) bearing attachment pins (5) to the boot. The block (4), by means of a vertical-axis joint (3), is rotatable with respect to the base (2), in order to define two use configurations, respectively a hooked (K) configuration and a non-hooked (W) configuration of the pins (5) to the relative boot. The joint (3) is defined by a vertical-axis hub (40), solidly constrained to the block (4), projecting downwards and destined to rotatably couple with a circular seating (20) realised in the base 2. Positioning organs (30) are associated to the joint (3), destined to define and elastically stabilise the two use configurations (K, W) of the heel piece (1). Calibration organs (50) are in turn associated to the positioning organs (30), which calibration organs (50) are destined to vary resistance to rotation offered by the block (4) from a minimum to a maximum.</p> |
