The latch (6) consists of a fitted part separate from the lever, sliding transversally to the plate, and the base also comprises a mobile element, like a shoe (16) which removes play between the plate and the slider, and may be moved to an active or inactive position by action on the release lever.

Abstract: A binding mounting system for releasably mounting bindings on a ski apparatus comprises a binding plate having a front end and rear end, a first mounting structure positioned adjacent to the front end of the binding plate, a second mounting structure positioned adjacent to the rear end of the binding plate. The first mounting structure is positioned coextensive with a front mounting location of the ski apparatus, and the second mounting structure is positioned coextensive with a rear mounting location of the ski apparatus. The first mounting structure is releasably attachable to the front mounting location, and the second mounting structure is releasably attachable to the rear mounting location. Several varieties of mounting structures are used to encompass the ski apparatus mounting techniques.

Abstract: A ski binding in which a heel part can be adjusted in the longitudinal direction relative to a guide fixed to a ski and can be actuated by hand. In order to prevent the connecting web of the opening lever disengaging from the locking plate s well as involuntary unlatching of the heel part due to external influences, the invention provides that the connecting web of the opening lever is designed in a U-shaped manner, and that the connecting web, bent in the direction of the upper side of the ski, forms protecting web which terminates flush with the guide fixed to a ski. A restoring lug assists the function of the spring, which acts on the locking piece, the restoring lug being actuable, by way of an edge of the connecting web, by pulling on the opening lever and being formed by being bent out of the locking plate.

Abstract: A snowboard binding system employs a frame system which substantially encloses the boot and includes at least two attachment points for engagement by a corresponding binding portion mounted to the snowboard. Mounts engage the corresponding binding cables on the board. The binding system includes anchor straps for adjusting snugness of the boot to the binding frame and adjustable toe contact cable which in conjunction with a forward-lean slide and adjustment member enables variable pivot point selection at the front of the binding system. An adjustable highback pivotally mounts to the binding frame. The adjustment straps enable control of tension for medial and lateral leaning to further provide a variation of the binding system control as desired by the rider. Further, the boot sole remains flexible, since no rigid plate or the like is employed.

Abstract: A snowboard boot binding comprising a base adapted to receive a boot, an in-step pad adapted to cover the top of the boot, a rear support adapted to cover a heel and the back of the boot, the rear support being pivotedly mounted at the base. The in-step pad is attached to the base via tension cables passing through the sides of the base, coming out under the base below a pivot point and being attached to the rear support and progressing longitudinally along the rear support. The rear support is maintained in a vertical position by a spring loaded lever, which when pulled back, provides space to insert the boot and most importantly releases the tension in the cables, and which allows the easy insertion of the boot. Bringing the rear support back to its original position reestablishes the tension in the cables. The boot is thus firmly held in place by the combined effects of the pressure provided by the in-step pad and the rear support. For storage the rear support can be folded over the base, to save space.

The elongated holes allow for rotational adjustment of the binding. A hook-shaped structure extends from one side of the base with the hook facing outward. On the opposite side of the base is a camming structure with a downward and outwardly sloping surface ending in a bale-receiving notch.
