System for mitigating musculoskeletal stresses from head-related moments exerted on a person

A stress mitigation system for mitigating stresses in a wearer of a headgear, wherein the headgear is configured to apply a load on the wearer that is offset from a center of gravity of a head of the wearer so as to apply a first torque in a first torque direction on the head of the wearer, the stress mitigation system comprising:

• a first force transfer cable segment and a second force transfer cable segment, wherein each force transfer cable segment has a first end and a second end, wherein the first ends are mounted to one of the headgear and the bodywear member and the second ends are mounted to the other of the headgear and the bodywear member, wherein the first ends are laterally inboard from the second ends and are vertically spaced from the second ends sufficiently such that, during pivoting movement of the head of the wearer in a first pivot direction about a vertical axis, the first force transfer cable segment changes orientation towards a vertical orientation and the second force transfer cable segment changes orientation towards a horizontal orientation, and during pivoting movement of the head of the wearer in a second pivot direction about the vertical axis, the first force transfer cable segment changes orientation towards the horizontal orientation and the second force transfer cable segment changes orientation towards the vertical orientation;
• and
• a tensioning device including a cable segment biasing member is biased under flexure so as to apply a restoring force that increases tension in any of the first and second force transfer cable segments that changes orientation towards the vertical orientation, and reduces tension in any of the first and second force transfer cable segments that changes orientation towards the horizontal orientation.
