A binding for a snowboard or other type of board that has a base plate structure formed of a lower plate that is mountable on a board; an upper plate that is adapted to receive a boot and is mounted above the lower plate in a spaced relationship; and a spring-based suspension system connecting the upper plate to the lower plate. The suspension system has a plurality of springs, one spring being connected between a flange of the upper plate and a corresponding flange on the lower plate. A boot attachment apparatus is connected to the base plate structure.

What is claimed is: 1. A binding for a snowboard or other type of board, comprising: a base plate structure comprising: a lower plate that is mountable on a board; an upper plate that is adapted to receive a boot and is mounted above the lower plate in a spaced relationship; the upper and lower plates each comprising a plurality of flanges extending outwards from a footprint area of the plates, the flanges of the upper plate being aligned with corresponding flanges of the lower plate, each flange having an aperture formed therethrough; a spring-based suspension system connecting the upper plate to the lower plate, comprising: a plurality of springs, one spring extending between each flange of the upper plate and its corresponding flange on the lower plate, with the ends of each spring being substantially in contact with the flanges of the upper and lower plates; a plurality of bolts, one bolt extending upwardly through each aperture of each flange of the lower plate and being fixedly mounted thereto, each bolt non-fixedly passing through the corresponding aperture of the upper plate, a spring around each bolt; an end cap attached to the distal end of each bolt above the upper plate so that when there is no weight on the upper plate the springs force the upper plate up against the end caps and when weight is applied to the upper plate, the upper plate can compress the springs and move down relative to the bolt away from the end caps; wherein the spring-based suspension system is compressed by the application of force and thereby absorbs vibration and shock. 2. The binding of claim 1 further comprising spring seats engaging each end of each spring. 3. The binding of claim 1 further comprising a pair of lateral brackets mounted on the top of the upper plate, one along each lateral edge, inside the laterally extending flanges. 4. The binding of claim 1 further comprising a boot attachment apparatus connected to the base plate structure. 5. The binding of claim 4 wherein the boot attachment apparatus comprises: a heel portion; a toe retainer apparatus; a mid-boot retainer apparatus. 6. The binding of claim 5 wherein the toe retainer apparatus comprises a toe retainer, a strap connecting the toe retainer to the binding, and a tensioning and releasing buckle in the strap. 7. The binding of claim 6 wherein the mid-boot retainer apparatus comprises a mid-boot retainer, a strap connecting the mid-boot retainer to the binding, and a tensioning and releasing buckle in the strap. 8. The binding of claim 5 further comprising a pair of lateral brackets mounted on the top of the upper plate, one along each lateral edge, inside the laterally extending flanges.
