Board sports dynamic systems and methods of use thereof

Abstract

A stance interface assembly for installation between a rideable board and a binding includes a base fixed to the board in an intermediate region, an annular flex ring surrounding the base and mechanically coupled to the board, the flex ring being tunable to vary at least one of axial stiffness, radial stiffness, or damping, and a binding interface plate supported for rotation about a vertical stance axis. The assembly may include a rotary bearing assembly supported on the flex ring, a tuning subsystem with a preload-maintaining fastener array and indexed orientation feature for directional damping, a pressurizable chamber in the flex ring for fluid-based stiffness adjustment, an actuation stage with a motor or servo for repositioning the binding interface plate, a manual lever with override priority, and a sensor suite with a controller for scheduling set-points and enforcing safety constraints. The system supports both manual and automated stance adjustments.
