Abstract

An adjustable steering column for motor vehicles, in which a steering axle (2), which is composed of parts that are telescopingly displaceable in relation to one another and is connected at its top end (3) to the steering wheel, is rotatably mounted in a housing (1), and this housing is supported in a holder (4) that is a rigid part of the body both pivotably around a transverse axis (7) and displaceably in the longitudinal direction of the steering column in relation to the body. The actually supported position is continuously lockable by two hydraulically acting piston-and-cylinder units (13, 14), which are rigidly articulated to the body, on the one hand, and are connected to the housing (1) in an articulated manner, on the other hand. One of the two piston-and-cylinder units (13) is connected to the housing (1) in an articulated manner via an angle lever (10) that is mounted in the holder (4) pivotably around a transverse axis (7), and both piston-and-cylinder units (13, 14) are aligned approximately in parallel to the longitudinal axis (8) of the steering column.
