Abstract: A binding element adapted to retain the end of a boot. It includes a body that bears on a jaw. The jaw is vertically movable, and its movement is transmitted to the return spring of the jaw, which constitutes a compensation for a backward fall. The sole of the boot is pinched between a support plate and sole-tightener of the jaw. The support plate is movably mounted about a horizontal and longitudinal axis so that a twisting of the boot causes an elevation of the jaw and thus, activates the compensation mechanism.

Abstract: Front ski binding designed to hold the end of a boot supported on a ski. The binding comprises a base (3) and a body (8) which moves in relation to the base (3) and parallel to a vertical median longitudinal plane of the ski. The body carries, moreover, a mechanism (15) for position retention of the front end of the boot. The front parts of the body (8) and the base (3) are connected, so as to allow the body (8) to pivot in relation to the base and parallel to the vertical, median longitudinal plane of the ski. An elastic return mechanism (30), distinct from the elastic return device (26) which returns the wings (21) of the position-retention mechanism, connects the body (8) to the base (3) and elastically returns the rear part of the body (8) toward the base (3).
