Abstract: An orthopedic device for supporting a lower back of a user includes a mechanical energy store, a pelvic element, an upper body element with a first force transmission element and an upper leg element with a second force transmission element. The upper leg element is arranged on the pelvic element such that it can be swivelled about a first swivel axis, the upper body element is movably arranged relative to the pelvic element, the first force transmission element can be engaged and disengaged with the second force transmission element by moving the upper body element relative to the pelvic element, and the mechanical energy store can be charged and discharged by swivelling the upper leg element relative to the upper body element when the first force transmission element is engaged with the second force transmission element.

Abstract: An orthopedic device for supporting a lower limb and/or a lower back of a user includes at least one upper joint element, at least one lower joint element which can be pivoted relative to the upper joint element, and at least one actuator configured to apply a torque to the upper joint element and/or the lower joint element. Application of a torque pivots the upper joint element and the lower joint element relative to each other. The orthopedic device also includes at least one ground contact element which is connected to the lower joint element such that when the orthopedicdevice is in the mounted state, the torque applied by the at least one passive actuator is transmitted by the ground contact element to a ground on which the user is located.

Abstract: The invention relates to an orthopedic device with an energy storage device 2 that comprises at least one cylinder 4, in which a first cylinder chamber 6, a second cylinder chamber 8, which is fluidically connected to the first cylinder chamber 6 by at least one fluid line 14, and a piston 10 are located, wherein the piston 10 is arranged relative to the cylinder 4 such that it can be displaced in such a way that by displacing the piston 4, an operating medium, which is a fluid, is conveyed through the at least one fluid line 14 from one cylinder chamber 6, 8 into the other cylinder chamber 8, 6, wherein the energy storage device 2 has at least one compensation volume 24, which is fluidically connected to the fluid line 14 via a fluid connection 22, and a first controllable valve 26, by means of which the fluid connection 22 can be opened and closed.
