Abstract: An adjustable steering column assembly includes a steering column and a lever moveable between an unlocked position and a locked position. The position of the steering column is adjustable when the lever is in the unlocked position and fixed when the lever is in the locked position. An anti-unlocking device is provided to prevent the lever from moving to the unlocked position from the locked position when a first force is applied to the steering column. The anti-unlocking device prohibits adjustment of the steering column when a first force is applied to the steering column. An example anti-unlocking device may include a member defining a slot, with the lever being at least partially insertable in the slot in the unlocked and locked positions. The member includes a wall defining a ramp surface configured to abut at least one surface of the lever when the first force is applied.
