  • Steering column slider assembly
    Patent number: 6540618
    Abstract: A steering column slider shaft assembly includes a shaft and yoke assembly having yoke at a first end and an attached non-cylindrical shaft extending therefrom to a second end. The second end is engaged with a non-cylindrical tube which forms a second end of a tube and yoke assembly, the tube being congruent with and adapted to slidably receive the shaft and provide a slip fit therefor. The shaft and yoke assembly and the tube and yoke assembly each have interengaging provisions which are over-molded or otherwise attached, for sealing the slider shaft assembly. The interengaging provisions also serve to limit extension of the slider assembly to resist inadvertent separation of the slider shaft assembly during assembly of the steering column.
