Abstract
In a crew member detecting device, an acoustic wave generator element mounted on a vehicle body generates a standing wave between the acoustic wave generator element and a bucket seat, and an acoustic wave receiver element is provided in the region of the standing wave, to detect the presence of a person on the bucket seat from variations in the output of the acoustic wave receiver element which are due to the movement of the person on the bucket seat.
