ABSTRACT:
A safety binding for a ski boot which includes a jaw adapted to retain a portion of the boot and to release under the effects of a force greater than a predetermined release threshold wherein the jaw is moveable between a stable equilibrium position and a release position in which the jaw releases the boot. The binding further includes an energization assembly which includes an elastic return device, such as a spring, for exerting a force on the jaw to bias the jaw into the stable equilibrium position; a shock absorber; and a compensation mechanism for varying the release threshold as a function of the intensity and duration of force whereby under the effect of a soft force. The release threshold is defined mainly by (1) the initial energization of the elastic return such that the shock absorber will not substantially change the compression of the spring, and (2) under the effect of a violet force, i.e. a brief force, the release threshold will increase because of the reaction of the shock absorber which opposes the compression of the spring, wherein such an increase in the release threshold is limited by the initial energization of the spring, increased by the additional energization that the shock absorber produces in the spring via the compensation mechanism.
