Abstract: Interface plate (1) intended to be secured to the upper face of a ski and capable of accommodating the toe piece and the heel piece of a safety binding, characterized in that it has a longitudinal recess forming a slideway capable of holding projecting parts situated under the toe piece and under the heel piece, while allowing the toe piece and the heel piece to slide inside the slideway with a view to adjusting the binding to the length of the boot, and in which the profiles (10, 11; 12, 13) of the zones of the slideway respectively holding the toe piece and the heel piece are geometrically identical.

Abstract: Safety binding for a ski boot, comprising a jaw having two arms (3, 4) which are independent so as to open in an opposite manner to one another when the boot is put on and are capable of retaining the boot vertically via its projecting sole (10), the jaw being able to pivot laterally counter to the action of a return spring. The arms (3, 4) bear on the upper (11) of the boot, while the sole (10) bears on front-bearing means (12, 13) which are located either on the arms or on the base (1).

Abstract: An alpine binding element equipped with a detachable ski brake (22) comprising a base (23) removably assembled with the binding element. The latter comprises a latch/spring assembly mounted in the base (3) of the binding element or in the rail carrying the body of the binding element, and the brake base (23) having a part (35, 36) interlocking with the latch/spring assembly in such a way that it is retained by the latch, which is itself held in the locked position by the spring.

Abstract: A bearing plate for a front binding, equipped with a member (8) for retaining the boot via a part of the sole (10) resting on the bearing plate (1), this bearing plate being compressible so as to adapt to the variations in thickness of the sole. The bearing plate forms a nonlinear system comprising an elastic body (12) which is precompressed on a rigid base (11) and opposes the deformation of the elastic body beyond a certain degree of deformation, so as to form a nonlinear system.
