Abstract: A safety binding for a ski adapted to maintain the front of a boot mounted on the ski. Each journal axis of a wing which pivots with respect to the body is engaged in at least one oblong hole for allowing relative displacement over a short distance of the wing with respect to the journal axis and it is in contact under the effect of an energy generating mechanism against a first end of the oblong hole. In the rest position, the wing rests, through its front edge, against a fixed support line of the body situated, in projection, in a vertical and transverse plane, between the journal axis of the wing and the end portion of the front arm in contact with the energy generating mechanism.

Abstract: A safety ski binding, preferably for engaging the front of a ski boot. The binding includes an elastic energization mechanism for the jaw of the binding and a separate arrangement for compensating for different sole thicknesses. In a specific embodiment, the binding is formed as a monobloc and includes a deformation zone to automatically accommodate soles of different thicknesses. The binding also includes a front fall sensor and a rear fall compensating mechanism to further compress the spring of the energization mechanism to lessen the amount of force required to release the boot during front and rear falls.
