Abstract
A human motion assistance device has upper back straps and is configured to attach to a user. A leg strap arrangement with lower back straps is configured to attach to the user. A differential assembly is connected between the upper back straps and lower back straps to reduce resistance of the upper torso harness and leg strap arrangement during gait. When crouching or lifting, the differential assembly transfers force to stretch and retract the upper torso harness and leg strap arrangement, which provides human motion assistance. The differential assembly can be implements as an x-bar, lever arm, pulley, gears, or tube. The leg strap arrangement has a knee pad adapted to cover a knee of the user. The knee pad opens along a segment. The upper torso harness has a shoulder strap and buckle. The leg strap arrangement is an elastic material.
