Abstract:
A method may be used to produce a steering column for a motor vehicle that includes an inner steering column tube that receives a steering shaft such that the steering shaft is rotatable about its longitudinal axis, an outer steering column tube that receives the inner steering column tube and has a longitudinal slot that extends in a direction of the longitudinal axis, and a clamping apparatus that can be switched over between a release position in which the inner steering column tube is adjustable relative to the outer steering column tube and a fixing position in which the inner steering column tube is fixed relative to the outer steering column tube. The longitudinal slot may have a greater width in the release position than in the fixing position. The method may involve, amongst other steps, manufacturing at least one single blank of the outer steering column tube and/or of the inner steering column tube using an extrusion process.
