Abstract: A snowboard binding assembly with an adjustable backplate that can be quickly and easily positioned at a desired angle of inclination while on the slopes and without any tools. The binding assembly has a baseplate attachable to the snowboard with a forward end, a rearward end, and a heel brace toward the rearward end shaped to conform to a heel of a rider's boot. A backplate is pivotally mounted to the baseplate to adjust the desired angle of inclination between the backplate and baseplate. A plurality of teeth are positioned on the rear face to form a rack of teeth arranged on the rear face along a longitudinal axis of the backplate, and a movable block is attached to the rear face of the backplate along at least a portion of the rack of teeth so that the block can move along the longitudinal axis of backplate.
