A drive mechanism having a drive motor that rotatably drives a threaded spindle against a specific braking force generated by a pretensioned spring of a friction brake arrangement. The drive motor and the threaded spindle are arranged coaxially in a housing tube of the drive mechanism, and components of the friction brake arrangement are arranged in a tubular brake housing, which is arranged in an axially and rotationally fixed in the housing tube. A first end of the brake housing has one or more radially inwardly directed first stop shoulders and at a second end of the brake housing has one or more radially inwardly directed second stop shoulders. The brake housing has at its first end a radially circumferential ring with one or more radially resilient spring arms extending axially toward the second end, at the free ends of which spring arms are arranged the second stop shoulders.

Drive mechanism

A trigger device includes an actuation device for converting an electrical activation signal into a movement of an actuator, a control device, which is connected to the actuation device for transmitting an actuation signal and which comprises receiving means for receiving an activation signal, and a power supply unit for supplying the actuation device and the control device with electric power.

A chair column arrangement of a swivel chair includes an upright tube which has a star base at its end region and in which a support tube is rotatably mounted. An end region of support tube remote from the star base protrudes from the upright tube and carries a seat at its protruding end region. A driven wheel is arranged non-rotationally coaxially on the support tube. A driving wheel arranged on a generator shaft of an electrical generator generating alternating current can be driven rotatably directly or indirectly by the driven wheel, wherein the electrical generator is arranged rigidly on the upright tube.
