A head restraint is mounted to the frame for translation along the guide. A motor is mounted to the frame for driving a threaded rod that is engaged with a fixed nut that is mounted to the guide for translating the head restraint. A pair of conductive brushes is provided on the guide and a pair of conductive contacts is mounted to the frame in electrical communication with the motor for providing power to the motor.
