Abstract
A rake lock assembly for a steering column assembly includes a component operatively associated with a rake bracket, the component including a trigger element, and a locking cam configured to be disposed within the rake bracket and to rotate about a rotational axis. The locking cam includes a first contact surface configured to interact with the trigger element, and a second contact surface having a plurality of teeth configured to interact with rake teeth. When an impact force acts on the steering column assembly and a rake bolt is shuttled in a first direction, the trigger element is configured to contact the first contact surface and rotate the locking cam about the rotational axis such that the second contact surface plurality of teeth and the rake teeth are disposed in interlocking meshing engagement to facilitate preventing a vehicle steering column from raking movement in a second direction.
