Friction damper

A friction damper comprising

• a. a housing having a longitudinal axis,
• b. a tappet that is displaceable along the longitudinal axis,
• c. a friction unit for generating a direction-dependent friction force on the tappet, wherein the friction unit comprises at least one friction lining that rests frictionally on the tappet and a friction lining carrier on which the at least one friction lining is held, wherein the friction lining carrier is arranged to be displaced relative to the tappet between an extraction position and an insertion position,
• d. a switching unit for variably setting the friction force, wherein the switching unit comprises
• i. a switchable actuator,
• ii. a locking element,
• iii. a force transmission unit which is mechanically coupled to the actuator and to the locking element, wherein the force transmission unit comprises a threaded spindle, wherein the force transmission unit comprises a gear, wherein the gear is configured as a reduction gear, wherein the actuator has a drive pinion on the motor shaft, which interacts with an internal toothing on the gear spindle, wherein the internal toothing is integrally designed in a sleeve section of the threaded spindle and is firmly coupled to the movement thread of the threaded spindle.
