Abstract
A method can be used to adjust a steering column for a motor vehicle that includes a casing unit in which a steering spindle is mounted rotatably about a longitudinal axis and at least two casing tubes that are guided so as to be adjustable relative to one another by adjustment travel in a longitudinal direction of the longitudinal axis. Along the adjustment travel, the casing tubes are extended farther out of one another in an operating region than in a transitional region, and a motorized adjustment drive acting on the casing tubes is actuated electrically for the relative adjustment of the casing tubes at a predetermined adjustment speed. To allow optimized switching between the operating region and the stowage position, a first adjustment speed is set in the operating region and a second adjustment speed, which is higher than the first adjustment speed, is set in the transitional region.
