Abstract
A highback for controlling a gliding board, such as a snowboard, through leg movement of a rider. The highback is provided with stiffness adjustability for accommodating the rider's particular riding preferences. Adjusting the highback stiffness allows the rider to selectively increase or decrease force transmission and board response based on individual riding preferences and/or riding conditions. Adjusting highback stiffness may also allow a rider to reduce pressure points between the highback and the leg, particularly the rider's calf muscle, for increased comfort while maintaining heelside support for board control. The highback includes a back member that may employ one or more sections that can be selectively adjusted to achieve a desired highback stiffness for board response and comfort. The degree of stiffness may be established by adjusting the flexibility of the highback at preselected locations of the back member. One or more interchangeable control elements may be mounted to the back member to adjust the highback stiffness.
