Title: Arrangement for sensing weight of an occupying item in vehicular seat

Abstract: Vehicle including a seat support structure, a cushion arranged thereon and having an upper surface for supporting an occupying item and that deflects downward as a function of weight of the occupying item, and a sensor system including a force-measuring device that responds to downward deflection of the cushion. An interrogator sends a signal to the force-measuring device and the force-measuring device transmits, after receipt of the signal from the interrogator, a return signal to the interrogator related to the response of the force-measuring device to the downward deflection of the cushion. In a method for obtaining an indication of weight of an occupying item of the seat, a signal is transmitted from the interrogator on the vehicle to the force-measuring device and from the force-measuring device, the transmitted return signal related to the response of the force-measuring device to the downward deflection of the cushion is received.
