Abstract
A steering column assembly includes a mounting bracket and a column jacket moveable relative to the mounting bracket. The mounting bracket defines a rake slot having rake slot teeth and a telescope slot having telescope slot teeth. A shaft extends through the rake slot and the telescope slot transverse to a longitudinal axis of the column jacket. A rake lock having rake lock teeth is disposed within the rake slot and a telescope lock having telescope lock teeth is disposed within the telescope slot. The shaft extends through and rotatably supports the rake lock and the telescope lock. The rake lock and the telescope lock rotate as the rake lock and the telescope lock move into interlocking toothed engagement with the slot teeth to avoid peak-to-peak contact between the lock teeth and the slot teeth, thereby permitting full meshing engagement between the lock teeth and the slot teeth.
