ABSTRACT:
A clamping mechanism for an adjustable steering column for a vehicle includes an actuating lever for actuating a clamping device which is coupled to an operating lever to which is mounted an operating handle. The two levers are interconnected intermediate their ends such that one lever can pivot and slide in a slot relatively to the other and the lever having a moveable fulcrum to allow for adjustment of the steering column. The fulcrum of the lever is fixed and the geometry is such that the clamping device always returns to the same, fully locked position, regardless of the rake and/or reach adjustment position of the steering column.
