Abstract: A telemark ski binding has a toe retainer pivotally coupled to a base. A lock assembly of the binding has an actuator assembly. The lock assembly is adjustable between a locked configuration and an unlocked configuration. The binding further has a heel retainer rotatably coupled to the toe retainer. When the lock assembly is in the unlocked configuration, the toe retainer is unlocked, and the toe retainer and heel retainer are both rotatable together substantially inline, relative to the base, around a first center point. When the lock assembly is in the locked configuration, the toe retainer is locked, and the toe retainer is restrained from rotating relative to the base. The heal retainer is rotatable relative to the toe retainer around a second center point. The second center point is at a different location from said first center point.

Abstract: The present invention relates to a ski binding used in telemark skiing. An exemplary system maintains a toe of a ski boot in association with a ski while permitting a heel of the ski boot to elevate to a top surface of the ski. The binding system comprises several complex subsystems, such as a toe mating mechanism, a toe plate system, a base plate system, a heel fastening mechanism, a sliding plate system, and rail system.
