Abstract
An actuating device for operating a safety unit mounted on a vehicle which includes a motor having an output shaft, a movable support for supporting the safety unit and moving it between its retracted and extended positions, and a non-mechanical switch arrangement that includes a pair of beam generators and sensors located in the path of the beams, and a plate for interrupting the beam and generating one control signal, and permitting passage of the beam to the sensor to generate another control signal. A control circuit is provided to operate the motor and movable support between its retracted and extended positions in response to the sensor's signals.
