  • Snow sled
    Patent number: 7559558
    Abstract: A snow sled comprising a seating portion that includes a lightweight space frame having a suspension-type seat stretched among the space frame. The sled further includes a steering portion and articulated steering mechanism 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 are removably attachable to the seating portion. The steering portion includes a ski support and a pair of front skis pivotably attached to the ski support. Chatter and movement of the front skis are dampened by a pair of boots that engage the ski support and the respective front skis.
