The invention provides a steering column assembly ( 10 ) for a vehicle. The steering column assembly ( 10 ) includes first and second steering column members ( 12, 14 ) engaged for movement relative to one another along one of a tilting path ( 16 ) and a telescoping path. The steering column assembly ( 10 ) also includes an electric lock ( 18 ) operable in a locked configuration and an unlocked configuration to selectively lock the first and second steering column members ( 12, 14 ). When the electric lock ( 10 ) is in the locked configuration, the first and second steering column members ( 12, 14 ) are locked with respect to one another. When the electric lock ( 10 ) is in the unlocked configuration, the first and second steering column members ( 12, 14 ) are moveable with respect to one another. The steering column assembly ( 10 ) also includes a sensor ( 20 ) operable to sense a condition corresponding to a vehicle crash. The sensor ( 20 ) emits a signal corresponding to the condition. The steering column assembly ( 10 ) also includes a controller ( 22 ) operable to receive the signal from the sensor ( 20 ) and controls the electric lock ( 18 ) to change from the locked configuration to the unlocked configuration in response to the signal.
