Abstract
The invention relates to a telescopic column with one outer and at least one inner rod element capable of telescoping relative to each other, where at least the outer rod element surrounds at least one ball arrangement with at least one ball, which acts as a rolling bearing between the outer and inner rod elements during telescoping movement. In order to create a telescopic column which, while having a low weight and low manufacturing costs, displays high lateral stability, the at least one inner rod element is provided with a longitudinal groove, which surrounds part of the circumference of at least one ball of the ball arrangement and serves as a ball guide. The longitudinal groove can provide two or more laterally separated running surfaces for the at least one ball. An area with a larger radial distance can be provided on at least one rod element between adjacent running tracks for an assigned ball, this being able to act as an abutment for the ball in the manner of an overload protector.
