Abstract
A steering column assembly includes a mounting bracket and a column jacket moveable relative to the mounting bracket to adjust a position of the column jacket. A rake plate is pivotably coupled to the mounting bracket and defines a rake slot having rake slot teeth. A telescope plate is pivotably coupled to the column jacket and defines a telescope slot having telescope slot teeth. 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 rake plate and the telescope plate pivot as the rake lock and the telescope lock move into interlocking toothed engagement 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.
