Abstract: Damper system for orthopaedic devices, with a proximal fastening device and a distal fastening device which are coupled to each other in such a way as to be displaceable relative to each other, with a first hydraulic or pneumatic damper device, which is arranged between the fastening devices and has a flexion chamber and an extension chamber separated from each other by a movable piston and connected fluidically to each other by at least one overflow line, wherein a second damper device with a parallel action, and with a velocity-independent hysteresis behaviour, is arranged between the fastening devices and is configured as a tube structure damper.
