Safety ski binding

Claim 1

Safety binding for releasably attaching a ski boot to a ski and allowing said ski to be fitted after release by rotating said boot on said ski, in a plane substantially parallel therewith, from a position transverse relative to said ski to a position wherein said boot is aligned with the longitudinal axis of and locked to said ski, said binding having (a) first connecting means secured to said ski and second connecting means secured to said boot, said connecting means being located under the skier's foot and one of them being substantially covered the other; (b) releasable retention means maintaining said boot upon said ski in the locked position and comprising at least a first locking element associated with the connecting means secured to said ski, and at least a second locking element associated with the connecting means secured to said boot, one of said locking elements having the form of a concave profile or housing and the other the form of a projection cooperating with said housing, said projection being resiliently retractable against the action of a resilient element in order to allow release of said boot; and (c) a system of guide ramps located in the immediate vicinity of said concave profile or housing, said guide ramps having a curved part extending laterally from said housing in a plane substantially parallel with the plane of contact between said boot and said ski and a projecting part vertically spaced from said housing, said projecting part protruding relative to said housing and to said curved part and cooperating with said resiliently retractable projection in such a manner that a vertical thrust applies said boot towards said ski to prevent its vertical separation during rotation of said boot prior to locking.
