Abstract
A lock for a steering column comprises a bracket disposed along a raking direction. A control shaft is supported for translation with the steering column. A tooth lock is disposed on the control shaft and comprises a lever and an actuator. The actuator is configured to cause the lever to rotate in an adjustment direction when a force is applied in the adjustment direction and so as to apply a locking moment to the lever when a force is applied in the locking direction. The bracket has a teeth disposed along the raking direction. The lever is configured for engaging, upon rotation in the locking direction, at least one tooth so as to resist translation in the raking direction. The lever is configured for disengaging, upon rotation in the adjustment direction, from the at least one tooth so as to selectively facilitate translation in the raking direction.
