    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: 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). When the supporting trunk (112) does not extend beyond the predetermined angle A, the torque generators (116, 118) do not impose resisting torques between the supporting trunk (112) and the thigh links (104, 106) during the entire range of motion of the thigh links (104, 106), thus enabling a wearer to walk, run, and sit without constraint while in a substantially upright position.

    Abstract translation: 外骨骼（100）包括两个扭矩发生器（116,118），两个大腿连杆（104,106）和可旋转地联接到大腿连杆（104,106）的支撑躯干（112）。 当穿戴者在矢状平面中向前弯曲，使得支撑躯干（112）相对于垂直方向延伸超过预定角度A时，至少一个扭矩发生器（116,118）在支撑躯干（112）之间施加阻力矩， ）和相应的大腿连杆（104,106），从而将力施加到穿着者的躯干上，并且大腿以帮助将佩戴者支撑在弯曲位置。 外骨骼（100）可以包括用于致动扭矩发生器（116,118）的主动或被动装置（116,134）。 当支撑躯干（112）不延伸超过预定角度A时，扭矩发生器（116,118）在整个范围内不会在支撑躯干（112）和大腿连杆（104,106）之间施加阻力转矩 大腿连杆（104,106）的运动，从而使得佩戴者能够在大致直立位置时无限制地行走，跑步和坐着。
