A snow glider comprises a longitudinally-extending runner for supporting a rider on ridden snow and having a generally central, longitudinally-extending slot. The glider further comprises an elevated rider-supporting deck and chatter-absorbing means straddling the slot for supporting the deck above the runner. Preferably, the bottom surface of the runner is preferably generally convex across its width, with curved outer edges that provide directional control to the rider when turning, and at least one longitudinally-extending, generally straight longitudinally-extending inner edge adjacent the periphery of the slot for greater directional control when the rider is going straight. To enhance controllability, the deck of the preferred embodiment is preferably coupled to the runner near the runner's outer periphery so that the force exerted by the rider is transmitted from his/her feet directly to the outer edges of the runner. To further reduce frictional contact with the snow, the bottom surface of the runner is preferably dimpled.

1. A snow glider comprising: a longitudinally-extending runner for supporting a rider on the ridden snow and having an elongated generally central opening;at least one deck supported above the runner for supporting the rider; andchatter-absorbing means including suspension arms extending longitudinally from the at least one deck to the runner for supporting the deck above the runner, at least a portion of the suspension arms straddling the generally central opening to support the deck on opposite sides of the opening. 2. The snow glider of claim 1 wherein the chatter-absorbing arms couple the at least one deck to the runner closely adjacent the runner's periphery. 3. The snow glider of claim 2 wherein the snow-facing bottom surface of the runner is generally convex across its width. 4. The snow glider of claim 3 wherein the convex shape has a pitch in the range of approximately 1°-40°. 5. The snow glider of claim 4 wherein the pitch is an angle lying within the range of approximately 1°-40°. 6. The snow glider of claim 2 wherein the chatter-absorbing arms are approximately 10-30 cm long. 7. The snow glider of claim 2 wherein the chatter-absorbing arms couple the deck to the runner at locations near the runner's periphery. 8. The snow glider of claim 2 wherein the surface area of the at least one deck is between approximately 15-30 cm wide and between approximately 20-45 cm long. 9. The snow glider of claim 2 wherein the thickness of the at least one deck is approximately 2 mm to 2 cm. 10. The snow glider of claim 2 wherein the deck has a composite tube-like frame. 11. The snow glider of claim 2 wherein the at least one deck has a plurality of weight-reducing openings. 12. The snow glider of claim 2 wherein the at least one deck has a rider-facing top surface having a row of internally threaded holes to which a binding attachment rail can be secured with screws. 13. The snow glider of claim 1 wherein the elongated generally central opening extends approximately 30% to 90% of the runner's length. 14. The snow glider of claim 1 wherein the elongated generally central opening extends 10% to 50% of the runner's width. 15. The snow glider of claim 1 wherein the runner has a curved outer metallic edge that runs the length the runner at each side to provide directional control to the rider when turning. 16. The snow glider of claim 1 wherein the runner has at least one generally straight longitudinally-extending inner edge extending longitudinally adjacent the periphery of the elongated opening to provide the rider with directional control when the rider is going in a generally straight direction. 17. The snow glider of claim 1 including means for stopping the movement of the at least one deck towards the runner prior to its contacting the runner as the at least one deck undergoes chatter-absorbing movement in a direction generally perpendicular to the runner. 18. The snow glider of claim 17 wherein the stopping means includes a structural component affixed to the deck and extending generally downward therefrom towards the runner to be stopped at the limit of travel. 19. The snow glider of claim 18 wherein the stopping means includes a structural component formed integrally with the deck and extending generally downward therefrom towards the runner to be stopped at the limit of travel. 20. The snow glider of claim 18 wherein the stopping means includes a structural component affixed to the runner and extending generally upward therefrom towards the deck to stop the deck at its limit of travel. 21. The snow glider of claim 18 wherein the stopping means includes a structural component formed integrally with the deck and extending generally upward therefrom towards the deck to stop the deck at its limit of travel. 22. The snow glider of claim 21 wherein the runner has at least one generally straight inner edge extending longitudinally adjacent the elongated opening to provide the rider with directional control when the rider is going in a generally straight direction. 23. The snow glider of claim 17 wherein the elongated generally central opening extends approximately 30% to 90% of the runner's length. 24. The snow glider of claim 17 wherein the elongated generally central opening extends 10% to 50% of the runner's width. 25. The snow glider of claim 17 wherein the runner has a curved outer metallic edge that runs the length the runner at each side to provide directional control to the rider when turning. 26. The snow glider of claim 25 wherein the runner has at least one generally straight inner edge extending longitudinally adjacent the elongated opening to provide the rider with directional control when the rider is going in a generally straight direction. 27. The snow glider of claim 1 including a piston-type shock absorber mounted between the deck and the runner. 28. A snow glider comprising: a longitudinally-extending runner for supporting a rider on the ridden snow and having an elongated generally central opening;at least one deck supported above the runner for supporting the rider;chatter-absorbing means for supporting the deck above the runner, at least a portion of the chatter-absorbing means straddling the generally central opening to support the deck on opposite sides of the opening; andmeans for stopping the movement of the at least one deck towards the runner prior to its contacting the runner as the at least one deck undergoes chatter-absorbing movement in a direction generally perpendicular to the runner, the stopping means being positioned to couple the force exerted by the rider to the periphery of the runner.
