Abstract

A clamping device for an adjustable steering column of a motor vehicle for the detachable fixation of a housing accommodating the steering column at a bracket rigidly connected to the body of the motor vehicle. The device has at least two friction surface pairs, each of which consists of at least one friction surface arranged at the body bracket and at least one corresponding friction surface at the steering column housing and a tilting pin mechanism for generating the clamping forces, which is axially movable along an axis arranged at right angles to the plane of the friction surface pairs. The tilting pin mechanism has two individual, separately adjustable clamping mechanisms which can be actuated together via a synchronizing sleeve. The synchronizing sleeve may have a toothed belt gear on its outside, or it may have a hand lever.
