Technical Field
The present invention relates to a steering column, and more particularly, to a rake adjustment assembly of a steering column.
Known rake adjustment assemblies include teeth that mesh together when the rake adjustment assembly is placed in a locked position after a desired rake adjustment is made. Unfortunately, if the teeth between the elements are not properly aligned when locked, damage to the teeth may occur and/or it may be difficult to lock the rake adjustment assembly.
Accordingly, it is desirable to design a rake adjustment assembly that is more robust, reliable, and has self-aligning teeth.
