  • Neck supporting exoskeleton
    Patent number: 11938074
    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.
