Patent ID: 11826298

Abstract:
A human motion assistance device has an upper torso harness and a preloaded leg strap arrangement affixed to the upper torso harness. The preloaded leg strap arrangement has an X-bracket connected to the upper torso harness. The preloaded leg strap arrangement further uses a plurality of blocks and a preloaded strap routed through the blocks and connected to the X-bracket. The preloaded leg strap arrangement further uses a knee pad with a split seam. The preloaded strap is under tension, even when the human motion assistance device is in a relaxed state. The preloading provides an immediate force which increases under a loaded state. The potential energy stored during the loaded state is released when transitioning from a standing position to a crouched, squatting, or seated position. The configuration allows for maximizing the energy storage without putting excess shoulder pressure on the user when standing.
