<p>A safety binding for a cross-country ski including a longitudinal rib bordered laterally by two longitudinal surfaces which are substantially planar and are adapted to engage a groove in a shoe sole. The rib is independent of and displaceable laterally with respect to the longitudinal surfaces and supports an apparatus defining a transverse journal axis around which the anterior zone of the shoe is adapted to pivot. Also provided is a locking apparatus for immobilizing the rib in a skiing position in which the rib is substantially aligned with the longitudinal axis of the ski and for permitting lateral displacement of the rib in response to a lateral force on the rib which exceeds a predetermined threshold produced by the locking apparatus. This binding has a mass and a cumbersomeness which is comparable to the mass and cumbersomeness of a conventional binding.</p> |
