Safety binding for e.g. off-track ski, has heelpiece comprising cam and lateral post formed as single piece, where cam and locking piston generate immobilization of body with respect to post or release of rotation of body relative to post

摘要

The binding has a heelpiece (7) comprising a cam (201) and a lateral post (200) formed as a single piece using synthetic material. The cam is extended transversely with respect to the post. A locking body of a shoe is rotatably mounted on the cam around a transverse axis. A return spring is housed in the body. A locking piston is housed in the body and plated by the spring in contact with the cam. The locking piston and the cam generate, according to their relative position, immobilization of the body with respect to the post or release of rotation of the body with respect to the post.
