Abstract
A passenger detecting system is disclosed, that comprises a seat, a plurality of electrodes disposed at predetermined intervals on at least the front surface of the seat, an oscillating circuit for generating a weak electric field between at least one particular electrode (referred to as a first type electrode) of the electrodes and the other electrodes (referred to as second type electrodes), a current/voltage converting circuit for detecting displacement currents that flow corresponding to the weak electric field and for converting the displacement currents into respective voltages, a controlling circuit for detecting a seating pattern of an passenger or the like on the seat corresponding to output signals of the current/voltage converting circuit, and an air bag device for inflating an air bag in case of a collision.
