Abstract
A column unit, in particular a chair column unit, including a base tube (310) and a pneumatic spring (318), further comprises an axially movable guide bushing (314) which is inserted in an axially movable manner in the upper end (310b) of the base tube (310), and which encloses an axially movable part (318b) of the pneumatic spring (318). An exit movement of the guide bushing (314) can be effected, e.g., by driver- or pusher-stops (326, 314g). The exit movement is restricted by pullout-restricting stops (316, 312g) which are releasable for the disassembly of the column unit.
