Telescopic column with rolling bodies between inner and outer tube, which also has screening tube between inner and outer tube

摘要

The column (S) consists of an inner tube (1) and an outer tube (2), between which is a cage for rolling bodies. A screening tube (7) is also fitted between the inner and outer tubes, which is displaced by the cage to an extension screening position. This covers the out-of-sight region of the column in the extended position.
