Abstract
A binding having a jaw is adapted to pivot laterally around two converging support lines on a support against the bias of an elastic mechanism. The binding also includes two lateral wings for receiving a front end of the boot, and a support zone positioned between the wings. The support zone is adapted to contact the front end zone of the boot along a line which intersects a transverse plane passing through the support lines above their convergence point. As a result, when a torsional fall is combined with a frontward fall, the torsional component of the fall causes the boot to apply lateral pressure to one of the wings, thereby providing a torque or moment on the jaw. The frontward component of the fall causes the boot to apply frontward pressure on the support zone, thereby increasing the torque experienced by the jaw in the direction of the torque resulting from the torsional component of the fall.
