Abstract: A position lock for a steering column assembly is provided. The position lock includes an outer cam. Also included is an inner cam defining a slotted aperture to receive a rake bolt operatively coupled to the outer cam, the slotted aperture facilitating shuttling movement of the rake bolt therein. Further included is a tooth lock operatively coupled to the inner cam, the tooth lock rotatable between an unlocked position and a locked position. Yet further included is a pin extending through the inner cam and operatively coupled to the outer cam, and rotation of the outer cam facilitates movement of the tooth lock out of engagement with the rake lock tooth wall when rotating between the locked position and the unlocked position.

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.
