<p>A telescopic helm (10) having a steering drive shaft (12) and a steering wheel shaft (14) separated by a collet (32) to axially adjust the position of a steering wheel hub (18) of a vehicle. The steering wheel shaft (14) has an inner wedged surface (20) and the collet (32) has an outer wedged surface (22) which, when in contact with each other, produce a radially, inwardly directed force that grips the steering drive shaft (12) preventing axial movement of the steering wheel shaft (14). When the wedged surfaces (20,22) are moved out of contact with each other, the radially inwardly directed force is relieved allowing the steering wheel shaft (14) to move axially relative to the support structure (24). the assembly is characterized by the collet (32) having fingers defining the wedged surfaces (22) for clamping engagement inwardly about the steering wheel shaft (14).</p> |
