ABSTRACT:
This invention is a lumbar-friendly cargo carrier sled that can be used by humans to move cargo across rough or snow covered terrain and is adapted for use in conjunction with skis or wheels. The sled has an adjustable harness that articulates, by pivoting about three points in two planes. The sled frame itself flexes under dynamic loading conditions to absorb shock, and the harness is adjustable in length to transfer the majority of the load more directly onto the pelvic girdle region via a curved hip plate. The overall result is a lumbar—friendly pack sled that has the capability of maximizing the load that can be transported while minimizing the strain upon the human body.
