Abstract: A leg support exoskeleton is strapped on as wearable device to support its user during squatting. The exoskeleton includes a knee joint connected to a first line and a second link, which is configured to allow flexion and extension motion between the first link and the second link. A force generator has a first end that is rotatably connected to the first link. A constraining mechanism is connected to the second link and has at least two operational positions. In a first operational position, the second end of the force generator engages the constraining mechanism, where the first link and the second link flex relative to each other. In a second operational position, the second end of the force generator does not engage the constraining mechanism; the first link and the second link are free to flex and extend relative to each other.

Abstract: A human interface device is configured to be coupled to a trunk of a person and comprises a frame, a fabric coupled to said frame configurable to be under tensile forces, and a belt configured to be coupled to two side edges of said frame wherein when said belt is worn by said person, an area of said fabric will be pushed against the person's lower back conforming to the shape of the lower back of said person. In operation when said human interface device is worn by said person, the weight of any load coupled to or supported by said frame will be partially supported by the friction force between the area of said fabric which is pushed against the person's lower back, and the person's lower back allowing said person to carry said load.

Abstract: An exoskeleton leg is wearable by a person. The exoskeleton includes a thigh link configured to move in unison with the thigh of the person, a shank link rotatably coupled to the thigh link and comprising at least one tooth, and a locking block coupled to the thigh link and comprising a locking face. Moreover, when the at least one tooth of the shank link contacts with the locking face, the shank link is prevented from flexion motion relative to the thigh link, but is allowed to extend relative to the thigh link.

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.
