ABSTRACT:
A steering column rotary tilt locking mechanism. The mechanism includes a rod pivotally interconnecting upper and lower column members and a sleeve supported about the rod. The rod and sleeve have selectively engageable surfaces. The sleeve has opposed slots with one end of each slot having axis offset from the other slot. Upon rotation of the sleeve, the sleeve moves out of perpendicularity relative to the shaft such that the slots bind against the shaft and the sleeve moves off center relative to the rod and binds thereagainst.
