Abstract: An adjustable vehicle steering column clamping mechanism for a rake and reach adjustable steering column includes a steering column support bracket which has two flanks extending on either side of a steering column outer tube, each flank incorporating a slot to permit rake adjustment. A reach adjustment bracket has two flanks which extend on either side of the tube and lie adjacent the flanks of the bracket, the flanks also having slots extending parallel to the tube axis for reach adjustment. The flanks are spaced from the tube so as to accept heads of clamping bolts operated by a handle acting on associated clamping parts mounted on the bolts. The arrangement enables the bolts to be located on a substantially on-center line passing at right angles through the axis of the steering column.
