Abstract: A system for selectively locking a steering column comprises a lock bolt configured for translating along its axis so as to extend, in a first state, a first length from a base and, in a second state, a second length from the base. A motor is supported by a housing and has an output shaft. A driving platform with driving ramps is disposed about the lock bolt and coupled to the output shaft. A driven platform is disposed about the lock bolt, between a shoulder of the lock bolt and the driving platform. The driven platform is configured for interacting with each of the driving ramps to define a separation distance that depends upon a rotational position of the driving platform. The driven platform is also configured to cooperate with the shoulder of the lock bolt such that translation of the driven platform causes the lock bolt to translate.
