ABSTRACT:
A clamp for capturing an adjusted position of a motor vehicle steering column including a stationary bracket having planar sides on opposite sides of the steering column, vertical slots in the planar sides of the stationary bracket, and a rotatably immobilized bolt spanning the planar sides of the stationary bracket through the vertical slots. A primary nut includes a frustoconical shoulder and a tubular boss. The primary nut is screwed onto the bolt on one side of the stationary bracket and cooperates with a head of the bolt on the other side of the stationary bracket in squeezing together the planar sides of the stationary bracket. A plastic operating lever of the clamp has a lateral bore around the tubular boss on the primary nut and a frustoconical cavity which faces the frustoconical shoulder on the primary nut. A secondary nut screwed onto the tubular boss on the primary nut thrusts the frustoconical shoulder into the frustoconical cavity to couple together the plastic operating lever and the primary nut for unitary rotation. The secondary nut seats against an annular land at the base of the tubular boss to limit the thrust of the frustoconical shoulder into the frustoconical cavity.
