Patent attributes
A snowboard binding is provided having a base to accommodate the boot of the user and keep it in a fixed position on the base; and a highback. The highback is adapted to allow the leg of a user to articulate through a range of motion. Attached to the highback is a system of springs or elastic members for returning the leg of the user to a neutral position relative to the board in the absence of an applied counterforce. For example, the highback can be attached to the base in such a manner as to allow the highback to articulate in a range extending from a forward position to a neutral position, and optionally to a rearward position, the neutral position being disposed between the forward position and any rearward position. In this binding, a tensioning member is affixed to the highback in such a manner as to resist articulation of the highback to the forward or the rearward position, and to apply a force to the highback to return it to the neutral position in the absence of an applied counterforce. Alternatively, the highback can be affixed to the base so that it does not articulate in use, so that the position of the highback is fixed relative to the base. In this case, the articulation of the user's leg results in movement of the leg away from the highback. Straps having an elastic portion and a rigid portion of defined length are attached to the highback and to the base to hold the foot in place. In the absence of an applied counterforce, for example when the user is airborne, the elastic straps draw the user legs back into a neutral position against the base and highback.
