Abstract: A locking mechanism for an axially adjustable steering column includes a lock cam including a cam portion and a hub portion, wherein the cam portion and the hub portion are independent, separately formed components. The locking mechanism also includes a pin extending through the cam portion to permit the cam portion to pivot. The locking mechanism further includes a toothed portion formed on the cam portion for pivoting into engagement with teeth associated with the axially adjustable steering column in a locked position and out of engagement with the teeth in an unlocked position. The locking mechanism yet further includes an interface surface on the hub portion that includes at least one angled surface that interfaces with an adjustable lever and biases the cam portion from the locked position to the unlocked position.
