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.
