Abstract
An adjustable steering column assembly having an outer jacket, an inner jacket, and a tilt housing. A longitudinal locking device moves between released and engaged positions allowing and preventing longitudinal movement of the inner jacket relative to the outer jacket. A tilt locking device moves between released and engaged positions allowing and preventing tilting movement of the tilt housing relative to the inner jacket. A control lever is coupled to both of the longitudinal locking device and the tilt locking device for simultaneously moving the devices between the released and engaged positions. The longitudinal locking device has first and second members each having interengaging chamfers. The first member has an engagement surface abutting an abutment surface of the inner jacket when in the engaged position to prevent the longitudinal movement of the inner jacket relative to the outer jacket. The engagement and abutment surfaces are preferably uninterrupted along a longitudinal axis to provide an infinite number of adjustment positions for the inner jacket.
