Abstract
A steering column including a mast jacket pivotable up and down for vertical adjustment of the steering column and variable lengthwise for horizontal adjustment of the steering column. A clamp includes a first rotatable screw shaft on a stationary bracket perpendicular to a longitudinal centerline of the steering column, a second rotatable screw shaft on the mast jacket parallel to the longitudinal centerline of the steering column, a first split nut on the first screw shaft, and a second split nut on the second screw shaft. The first split nut and the first screw shaft cooperate in converting vertical adjustment of the steering column into idling rotation of the first screw shaft. The second split nut and the second screw shaft cooperate in converting horizontal adjustment of the steering column into idling rotation of the second screw shaft. A manual operating lever of the clamp rotates a control shaft which squeezes the first and the second split nuts against the first and the second screw shafts to frictionally couple the split nuts and the screw shafts and thereby capture the position of the steering column.
