  • Patent number: 9492300
    Abstract: An exoskeleton designed to be worn by a user is generally configured to support and transfer the load supported by the head, the neck and/or the torso (shoulders, chest and/or back) of the user down to the ground. The exoskeleton is generally passive and comprises at least three interconnected sections: torso, hip, and leg sections. Each of the sections generally comprises of a plurality of interconnected rigid members which form the load-bearing structure of the exoskeleton. When a user wears the exoskeleton, load normally carried by the head, neck and/or torso of the user is at least partially supported and transferred to the ground by the exoskeleton, thereby reducing the load effectively supported by the user itself. The leg sections of the exoskeleton are designed to ensure that the load-bearing final location is located on the inner side of the feet, in accordance with human biomechanics.

  • Publication number: 20150045703
    Abstract: A lower extremity orthotic control system determines a movement desired by a user, particularly with a user employing gestures or other signals to convey or express their intent to the system, and automatically regulates the sequential operation of powered lower extremity orthotic components. In a particular application, the orientation of a stance leg is used to determine when the user wants to initiate a step, as well as when the user is in a safe position from which to take a step. The invention has particular applicability for use in enabling a paraplegic user to walk through a controlled operation of a human exoskeleton coupled to the user's lower limbs. A controller receives inputs regarding a motion desired by the user, determines the desired motion and then controls the movement of the user's legs or limbs through actuation of the exoskeleton.

  • Patent number: 8784344
    Abstract: A pelvic frame (20) for a walking assistance device (10) is configured to be worn on a pelvic part of a user, and comprises a main frame (22) extending from a lower back of the user to either side of the user, an abdominal belt (30) attached to the main frame at base ends thereof, extending along an inner periphery of the main frame (22) and configured to be detachably passed along an abdominal part of the user, and a pair of stabilizer member (90, 92) each having a base end attached to a free end part of the main frame (22) and a free end engaging the abdominal belt (30). Because the two free end of the main frame (22) are joined by the stabilizer members (90, 92) in cooperation with the abdominal belt (30), the stiffness and mechanical strength of the main frame (22) is effectively enhanced, and the weight of the main frame and material cost can be minimized. Also, the deformation of the pelvic frame (20) during use can be minimized, and this contributes to the comfort of the user.

  • Publication number: 20140200491
    Abstract: An orthotic system includes a controller, a joint and a fail-safe system for the joint. In a preferred embodiment, the orthotic system is an exoskeleton, the joint is a knee joint and the fail-safe system is a normally engaged brake that is controlled by the controller. The brake is engaged when the controller fails or the exoskeleton is powered off. The exoskeleton also includes an electrical or mechanical brake disengagement mechanism, separate from the controller, so that an exoskeleton user can disengage the brake when desired. The exoskeleton can also include an override mechanism that prevents the brake disengagement mechanism from functioning when the exoskeleton is powered on and the controller has not failed. Additionally, the exoskeleton can include a user interface at one location, with the brake disengagement mechanism located at a different, limited access location, so that the user cannot accidentally activate the brake disengagement mechanism.

  • Patent number: 8740822
    Abstract: An actuator is reduced in weight without impairing a walking assist function, and this reduces the inertial moment of a leg link. A drive crank arm on the output shaft of the actuator and a driven crank arm fixed to a second link portion so as to be concentric to the joint shaft of a third joint portion are connected to each other via a connection link. The connection link is placed so that a line connecting a pivot portion at which the drive crank arm is pivotally mounted and a pivot portion at which the driven crank arm is pivotally mounted obliquely crosses a line connecting the output shaft of the actuator and the joint shaft of the third joint portion.

  • Publication number: 20140121575
    Abstract: According to a walking motion assist device 10, an assisting force T of a leg in a standing-leg period is controlled to indicate a greatest value or a maximum value in a first designated period (refer to the one-dot chain line and the two-dot chain line in t=t1 to t2). By doing so, in the first designated period (an initial period or a prior period) of one leg, a translation of a body derived from a floor reaction force acting on the one leg is largely prompted compared to other periods of the standing-leg period. A smooth starting of floor leaving and bending motion of the other leg is prompted so as to follow the translation of the body.

The exoskeleton includes a soft “backpack”-style harness that interfaces primarily with the user's waist, back, and shoulders. A chassis is provided to mount two positively-driven legs. Each leg includes features that are analogous to a human leg—a hip joint, a thigh, a knee joint, a calf, and a foot plate. Each leg of the exoskeleton is physically connected to one of the human user's legs. A thigh cuff is used to connect to the user's thigh. A shin cuff is used to connect to the user's calf. A foot plate rests beneath the sole of the user's foot. Power actuators are provided in the exoskeleton's hip and knee joints, and possibly additional locations. A user interface is provided in one or more locations so that the user can control desired functions of the exoskeleton.

  • Patent number: 8690801
    Abstract: A leg assist device with a control law suitable for assisting standing up motion is provided. The leg assist device is provided with an upper leg link, a lower leg link, a rotary joint, and a controller. The upper leg link and the lower leg link is attached to a leg of a user. The rotary joint rotatably connects the lower leg link to the upper leg link. The rotary joint also has an actuator which rotates the lower leg link. The controller controls the actuator so that the lower leg link angle matches a target angle. The controller has a torque limiter that limits the magnitude of the command torque that is output to the actuator. The controller sets a standing position angle corresponding to a user's standing position to the target angle, and raises an upper limit of the torque limiter as a user's hip height rises.
