ABSTRACT:
A safety binding for a ski including a body having a jaw for holding a ski boot and a support fixed to the ski. The support has a rear transverse face with two recesses therein, and a front transverse face. The body includes a transverse face having two projections thereon, each adapted to engage one of the recesses of the support. The recesses and projections define two lines of support converging at a point above the ski and disposed, respectively, on either side of the longitudinal plane of symmetry of the ski, so that the body can pivot along either one of the lines of support. A spring urges the rear face of a piston against the front transverse face of the support so that the rear traverse face of the support is urged against the transverse face of the body. The rear face of the piston includes two lines of reaction converging toward the ski. Because the two lines of reaction are on the rear face of the piston, the return moment of the binding increases continuously as the binding pivots further away from a central retaining position, thereby ensuring the rapid return of the binding whatever the displacement of the boot. In addition, because lines of reaction are on the rear face of the piston, the line of contact between the rear face of the piston and the support is constant.
