Abstract
A snow sled (100) comprising a seating portion (116) that includes a lightweight space frame (104) having a suspension-type seat (108) stretched among the space frame. The sled further includes a steering portion (120) and an articulated steering mechanism (112) that links the steering portion to the seating portion. The articulated steering mechanism allows the steering portion to be pivoted laterally relative to the seating portion so as to make the sled readily steerable. A pair of rear skis (164, 168) are removably attachable to the seating portion. The steering portion (120) includes a ski support (200) and a pair of front skis (204) pivotably attached to the ski support. Chatter and movement of the front skis are dampened by a pair of boots (228) that engage the ski support and the respective front skis.
