The automotive vehicle steering column (1), the height of which is manually adjustable, has a telescopic tube which consists of an inner tube (3) and an outer tube (2). On the inner tube in the overlapping region with the outer tube two sliding bushings (6, 8) arranged at a distance from one another, injection-moulded or cast-on are provided which have plane sliding faces. In the displacement region of the outer tube which has a polygonal cross-section sliding faces are assigned to said sliding faces. A sliding bushing (8) is provided in the vicinity of one end (7) of the inner tube (3) and mounted on an end piece (9) of a rotational rod (10) extending into the inner space of the inner tube (3). The end piece (11), lying within the inner tube, of the rotational rod (10) is connected to the inner tube (3). The sliding faces of the sliding bushing (8) which is fixed with respect to the rotational rod are offset in relation to the sliding faces of a sliding bushing (6) mounted on the surface of the inner tube (3) and can be aligned by means of a rotational deformation of the rotational rod (10) with respect to the sliding faces of the outer tube (2). …<??>The height-adjustable automotive vehicle steering column has a large adjustment range between the outer tube (2) and the inner tube (3). |
