Abstract
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.
