Abstract: The invention discloses a method and a production installation for producing a sub-assembly consisting of a plurality of parts joined together, in which the first part (1) and second part (2) are removed from a parts delivery site in the vicinity of a transport device and deposited oriented in position on one of a plurality of parts transport carriers of the transport device, and subsequently together with the parts transport carrier transported to an assembly station. The parts transport carrier is stopped in the assembly station in a holding position, whereupon the parts (1, 2), oriented towards one another, are moved by means of a vertical positioning device (200a, 200b) together from a transport position on the parts transport carrier into a preparation position, then positioned relative to one another, clamped and then joined to form a sub-assembly, whereupon the joined subassembly is again deposited on one of a plurality of parts transport carriers and transported away thereby.

Abstract: An adjustable steering column for a motor vehicle includes a setting unit displaceable in at least one setting direction, a holding unit nondisplaceable in this setting direction, and a securement device. In the opened state of the securement device, the setting unit is displaceable with respect to the holding unit for setting the position of the steering column and, in the closed state of the securement device, the setting unit is secured with respect to the holding unit by the securement device. The securement device includes a clamp bolt penetrating openings in the setting unit and holding unit, at least one tooth plate penetrated by the clamp bolt, which tooth plate comprises at least one toothing (set of teeth) with teeth directed away from the clamp bolt. The holding unit has at least one toothing (set of teeth), facing the clamp bolt for cooperation with the at least one toothing of the tooth plate in the closed state of the securement device.

The surface parts (20, 21) are arranged offset relative to one another by an offset (19). One of the parts (2, 3) comprises a mounting projection (6), which forms the mounting surface of the first part (2). The parts (2, 3) are positioned relative to one another so that the second part (3) forms the joint (16) with the first part (2) in the section of the first part (2) at which the dislocation density of the base material is lower than the dislocation density of the joint in a deformation area (18) on the first part (2) produced by cold forming.
