Safety ski binding

Safety ski binding designed to hold releasibly in place the front of a boot (2) mounted on the ski (3), comprising a body (4) attached to said ski and having a rear portion carrying a boot position-retention jaw (5) incorporating two lateral position-retention wings located opposite each other (7), an energy-generating mechanism (8) housed in said body and for returning said jaw elastically to a locked position, and a forward fall-compensation mechanism comprising a forward fall-sensor pedal (12) mounted on said ski to the rear of a front stop (1), said pedal having a rear portion jointed to a seating (13) attached to said ski for pivoting movement about a horizontal, transverse axis (14,23), said pedal being returned upward to a predetermined rest position by a spring (19,25) and having a forward extension (18) which, in the event that the skier falls forward, exerts a downward force on a movable control element belonging to the forward fall-compensation mechanism and housed in said body (4) of said front stop so as to lower a release threshold of said front stop, wherein a front end (12a,21a) of said pedal (12) is, in said predetermined rest position, located at a distance (d) above said movable control element (9) which approximates a standard tolerance for the thickness of a sole (6) of said boot, said tolerance being equal to a standard distance between maximum (e2) and minimum (e1) thicknesses of said sole 6.
