Abstract
A steering shaft lock actuator may include a motor having an output shaft, a drive train, and a lost motion device. The drive train may be coupled to the output shaft and may linearly urge a locking member to an unlocked position when the motor is energized. The lost motion device may be configured to store energy when the locking member is in the unlocked position and utilize the stored energy to drive the locking member toward a locked position with a steering shaft when the motor is de-energized.
