Ski binding and related process for releasing a boot from said binding

A ski binding (1) comprising:

• a casing (2) defining at least a seat (20) developing along a longitudinal axis (2a);
• elastic opposition means (3) housed in said seat (20) and configured, when subject to dilation along said longitudinal axis (2a), to produce a resistance force to opening of said binding (1) proportional to said dilation;
• adjusting means (4) suitable to adjust said resistant force and comprising at least:
• a cursor (40) housed in said seat (20), movable along said longitudinal axis (2a), operatively connected to said opposition means (3) and configured to determine, when moved along said longitudinal axis (2a), said dilation on said opposition means (3) so as to define at least:
• a minimum limit position wherein said opposition means (3) is minimally loaded or unloaded and exert said minimum force, and
• a loading position wherein said opposition means (3) undergoes said dilation so as to exert said greater resistant force than said minimum force,
• a control element (41) integral to said cursor (40) and movable along said longitudinal axis (2a) so as to be able to control the passage from said unloading position to said loading position and vice versa,
• locking means (5) operatively connected to said adjusting means (4) and suitable to lock said control element (41) when actuated;
• and characterized in that
• said adjusting means (4) further comprises a control element (42) kinematically constrained to said control element (41) so that, when said control element (41) translates along said longitudinal axis (2a), said control element (42) rotates around said longitudinal axis (2a), and
• said locking means (5) comprises an obstruction element (50) defining at least:
• a locking configuration wherein said obstruction element (50) interferes with the rotation of said control element (42) at least when said cursor (40) is in loading position by locking the motion of said control element (41) along said longitudinal axis (2a), and
• an unlocking configuration wherein said obstruction element (50) does not interfere with the rotation of said control element (42) and said control element (42) is free to rotate around said longitudinal axis (2a) so that said control element (41) could be moved along said longitudinal axis (2a) at least by said resistant force.
