Abstract

A manually height-adjustable steering column of power vehicle comprises an inner tube and an outer tube together forming a telescopeable tubular element, the inner and outer tubes having an overlapping and displacement region, the outer tube having a multi-cornered cross-section, two sliding bushes arranged in the region at a distance from one another and having sliding surfaces associated with the outer tube in the region, a rotary bar extending inside the inner tube and having two end pieces one of which is connected with the inner tube, one of the sliding bushes being arranged in the vicinity of an end of the inner tube and being mounted on the other of the end pieces, the other of the sliding bushes being mounted on an outer surface of the inner tube, the sliding surfaces of the one bush being offset relative to the sliding surfaces of the other sliding bush and orientable relative to sliding surfaces of the outer tube by a rotary deformation of the rotary bar.
