Abstract: A part for a ski binding comprising a carriage slidably attached to a base plate. One end of the base plate is fastened to the ski with fasteners, while its other end rests freely on the bottom of a U-shaped clamp, also fastened to the ski with fasteners. Attachment of the carriage to the base plate is accomplished by carriage structural features that retain the carriage in the clamp, and further carriage structural features that prevent the carriage from being vertically disengaged from the part of the base plate adjacent to the base plate's fastened end. However, such features allow the carriage to be moved horizontally back and forth relative to the base plate along the longitudinal axis of the ski. The ski binding part disclosed prevents a substantial amount of the vertical forces ordinarily experienced during skiing from being transmitted to the ski through the base plate, allowing the base plate to be made of lightweight construction.

Abstract: A binding for a snowboard has a base, side members extending upwardly and rearwardly from the sides of the base, towards the back of the base, with an arcuate member joining the rear ends of the side members. Fastening means on one side member and on one side edge of the board at the front provide for attachment of one end of each of two straps. Fastening means on the other side member and on the other side edge serve for attachment of a locking bar which in turn connects the other end of each strap to the side member and base. Attachment means are provided in the base for attachment to a snowboard. A snowboard for use in conjunction with the binding has a forward attachment position which provides for attachment of a binding inclined in either direction as desired, that is forward and to the right or forward and to the left, as desired, at about 45.degree.. A rear attachment position provides for attachment of the binding transverse of the board.

The assembly is guided slidably lengthwise of the ski in a mounting (3) attached to the ski. By means of a latching arrangement, the assembly is latchable in several slide positions. The mounting has at least one insertion aperture for the point of a ski pole (17). One of the units (7) carries spaced above the insertion aperture two bearing surfaces (11) for the ski pole (17) facing each other lengthwise of the ski, which permit a tilting movement of the ski pole (17) whose point has been inserted into the insertion aperture about an axis transverse to the lengthwise direction of the ski. The ski pole (17) serves as a lever which acts to displace the binding lengthwise of the ski without having to separate the ski (1) from the boot. The latching arrangement can be unlocked by a manual actuating device or by the ski pole (17).
