Abstract: A composite torsion box core for a snowboard comprises a center core member of lightweight wood or foam enveloped within a composite of a seamless, large diameter tubular sock. By expanding or compressing the length of the large diameter tubular sock during fabrication, the alignment of fibers within the sock is adjusted for programming a desired longitudinal and torsional rigidity relationship for the snowboard. Furthermore, side members, comprising separate composite torsion box cores having smaller diameter tubular socks, are disposed on opposite sides of the center core member and provide increased side strength for the overall torsion box core for enhancing the snowboard's edging strength without compromising torsional flexibility. Plural side members of various materials, sizes and spacing relative to each other are employed to provide snowboards having differing ride characteristics.
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.
