  • Patent number: 10864102
    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.

  • Publication number: 20200171648
    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.

  • Publication number: 20200121543
    Abstract: A neck supporting exoskeleton is configured to be worn by a person to support the person's head during backward extension motions of the person's neck. The neck supporting exoskeleton may comprise a torso frame configured to be coupled to the person's torso, a head pillow configured to contact the rear portion of the person's head during backward extension motions of the person's neck, a linkage allowing for relative motion between the head pillow and the torso frame in the sagittal plane of the person, and an actuator configured to impose a supporting force onto the head pillow. When the person's neck extension angle increases beyond an engagement angle, the actuator causes the linkage to impose a supporting force onto the head pillow resisting the backward extension motion of the head pillow and the person's head relative to the torso frame thereby providing a support for the person's head.

  • Patent number: 10463562
    Abstract: Provided is an exoskeleton assembly configured to be coupled to a wearer, including a plurality of members corresponding to body segments of the wearer. An adjustable first member includes a first component and a second component. The assembly further includes a first locking mechanism and a second locking mechanism, each configured to alternate between a locked position and unlocked position. When the first locking mechanism and the second locking mechanism are in the respective unlocked positions, the first component and the second component are free to slide relative to each other thereby adjusting the length of the first member. When either the first locking mechanism or the second locking mechanism is in the respective locked position, the first component and the second component are not free to slide relative to each other. The first member may be a spine assembly, a hip assembly, or a leg assembly.

  • Publication number: 20190231574
    Abstract: An exoskeleton includes two torque generators, thigh links, and a supporting trunk rotatably coupled to the thigh links. When a wearer bends forward in the sagittal plane such that the supporting trunk extends beyond a predetermined angle A with respect to vertical, at least one of the torque generators imposes a resisting torque between the supporting trunk and a corresponding thigh link, thus imposing a force onto a wearer's trunk and thighs to aid in supporting the wearer in a bent position. The exoskeleton may include an active or passive means for actuating the torque generators. When the supporting trunk does not extend beyond the predetermined angle A, the torque generators do not impose resisting torques between the supporting trunk and thigh links during the entire range of motion of the thigh links, thus enabling a wearer to walk, run, and sit without constraint while in a substantially upright position.

  • Patent number: 10357392
    Abstract: An exoskeleton (100) includes two torque generators (116, 118), two thigh links (104,106), and a supporting trunk (112) rotatably coupled to the thigh links (104, 106). When a wearer bends forward in the sagittal plane such that the supporting trunk (112) extends beyond a predetermined angle A with respect to vertical, at least one of the torque generators (116, 118) imposes a resisting torque between the supporting trunk (112) and a corresponding thigh link (104, 106), thus imposing a force onto a wearer's trunk and thighs to aid in supporting the wearer in a bent position. The exoskeleton (100) may include an active or passive means (116, 134) for actuating the torque generators (116, 118).

  • Publication number: 20180250187
    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.
