Abstract
A position lock for a steering column comprises a rake lock bracket, a tooth lock, a driver, and a spring. The rake lock bracket is fixed to the vehicle has a rake lock tooth wall that bounds a control slot and that defines a plurality of rake lock teeth. The tooth lock is coupled to the steering column for movement in a raking direction and supported for rotation about a tooth lock rotation axis. The driver, supported for translation with the tooth lock and for rotation about a driver rotation axis, is configured for contacting an actuation feature of the tooth lock so as to cause the tooth lock to rotate with the driver as the driver rotates within the active range of rotation of the driver. The spring is configured and arranged to apply a biasing moment to cause the tooth lock to rotate in a locking direction.
