Abstract

A steering device for motor vehicles has a steering shaft that is guided by a guide box (3) which is connected to a retaining console and, for example, clamped. The console has at least one sliding surface (8) along the axis of the shaft (1) which allows for a displacement path (20) with respect to the chassis (18) in case of a collision. A clamp (17) is provided for axial retention of the console (6) in an initial position of the displacement path (20). In this way at least one part of the clamped surface is slanted in relation to the vertical clamping device so that the clamping surfaces can move away from each other when the steering shaft is displaced and clamping is reduced.
