Abstract: A steering column having: an adjustable body intended to be mounted so as to be free to slide on a support and comprising two walls, a tube fixed to the adjustable body, a wedge inside the adjustable body and mobile between an unlocked position and a locking position inside the adjustable body between and at a distance from the walls, driving means and guiding means for the wedge, arranged with the wedge so as to be able to drive the wedge in a simple translation movement so that the wedge can come to bear against the adjustable body to immobilize the adjustable body relative to the wedge.

Abstract: A steering column mechanism a movable subassembly including a tube body and a steering shaft rotating around an rotation axis in the tube body, and a connecting articulation between the movable subassembly and a fixed support to guide pivoting of the movable subassembly relative to the fixed support around a pivot axis perpendicular to the rotation axis. An antitheft locking mechanism includes a locking body that is movable relative to the fixed support between a retracted position and at least one locking position and a matching member mounted on the shaft. In the locking position, the locking member ensures with the matching member positive locking to lock the rotation of the steering shaft. The locking member and the matching member have, in the locking position, a mutual contact zone which, in reference to a direction parallel to the rotation axis, extends on either side of the pivot axis.
