Abstract
In a steering column, a mechanism for adjusting its length and inclination relative to the vehicle body, the steering column consisting of a steering column casing or housing, interconnecting first and second steering column tubes, the first tube being displaceable and the second pivotable relative to the housing, the second steering column tube end cooperating with the housing and having a hub limitably rotatable in a seat in the housing about an axle located perpendicular to the tube and adapted to be arrested in different angular positions by a locking mechanism, an angularly adjustable coupling interconnecting the steering gear post and the steering axle extending through the first and second steering column tubes in the housing, a common control for releasing or locking both adjustments of the steering column, a piston axially displaceable and/or pivotably supported in the housing, and biased to a position wherein it locks the first steering column tube against actual displacement and causes the blocking mechanism to prevent the hub from rotation, the piston by actuation of the control being displaceable and/or pivotable to a first position wherein it allows actual displacemen…
