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 2):
The trunk support exoskeleton of  claim 1 , wherein at least one of the first and second torque generators comprises:\n an upper bracket configured to be coupled to the supporting trunk; a lower bracket configured be coupled to one of the first and second thigh links and rotatably coupled to the upper bracket; a pendulum rotatably coupled to the upper bracket; an engagement bracket slidingly coupled to the upper bracket; a compression spring rotatably coupled to the lower bracket from its first end and rotatably coupled to the engagement bracket from its second end, wherein the engagement mechanism is rotatably coupled to the upper bracket, and wherein:\n when the engagement mechanism is in its contacting position, the engagement mechanism is in contact with the engagement bracket and therefore prevents the engagement bracket from sliding on the upper bracket, causing the compression spring to provide a resisting torque between the upper bracket and the lower bracket, and \n when the engagement mechanism is in its non-contacting position, the engagement mechanism is not in contact with the engagement bracket and therefore the resisting torque between the supporting trunk and at least one of the first and second thigh links depends on the angle of the predetermined portion of the supporting trunk, such that: \n when the predetermined portion of the supporting trunk extends beyond the predetermined angle from vertical, the pendulum comes into contact with the engagement bracket and prevents it from sliding, causing the compression spring to provide a resisting torque between the upper bracket and the lower bracket; and \n when the predetermined portion of the supporting trunk does not extend beyond the predetermined angle from vertical, the pendulum is not in contact with the engagement bracket, the engagement bracket is free to slide on the upper bracket, and the compression spring does not provide resisting torque between the upper bracket and the lower bracket.
