Abstract:
A trunk supporting exoskeleton comprises: a supporting trunk; thigh links configured to move in unison with a wearer's thighs; and first and second torque generators located on both left and right halves of the wearer substantially close to the wearer's hip. The torque generators couple the supporting trunk to the thigh links, and generate torque between the thigh links and the supporting trunk. When the wearer bends forward such that a predetermined portion of the supporting trunk passes beyond a predetermined angle from vertical, a torque generator(s) imposes a resisting torque between the supporting trunk and the thigh link(s), causing the supporting trunk to impose a force against the wearer's trunk, and the thigh link(s) to impose a force onto the wearer's thigh. When the predetermined portion does not pass beyond the predetermined angle, the torque generators impose no resisting torques between said supporting trunk and respective thigh links.

Claim (Index 18):
A trunk supporting exoskeleton configured to be worn by a person to reduce muscle forces in a back of the person during forward lumbar flexion, the trunk supporting exoskeleton comprising:\n a supporting trunk configured to be coupled to a trunk of the person; first and second thigh links configured to move in unison with thighs of the person in a manner resulting in flexion and extension of respective first and second thigh links relative to the supporting trunk; and first and second torque generators located on both left and right halves of the person substantially close to a hip of the person, coupling the supporting trunk to the first and second thigh links respectively and configured to generate torque between the first and second thigh links and the supporting trunk, wherein when the person bends forward in a sagittal plane such that a predetermined portion of the supporting trunk passes beyond a predetermined angle from vertical, at least one of the first or second torque generators imposes a resisting torque between the supporting trunk and at least one of the first and second thigh links, causing the supporting trunk to impose a force against the trunk of the person and at least one of the first and second thigh links to impose a force onto the person's thigh and, wherein when the predetermined portion of the supporting trunk does not pass beyond the predetermined angle from vertical, the first and second torque generators, during an entire range of motion of the first and second thigh links, impose no resisting torques between the supporting trunk and the respective first and second thigh links, wherein the supporting trunk comprises: a lower frame substantially located behind the person configured to partially surround the person's trunk and coupled to the first and second torque generators from two sides of the person; a spine frame located behind the person rotatably coupled to the lower frame; and an upper frame coupled to the spine frame configured to be in contact with a general area of the person's trunk.
