Abstract:
A vehicle seat weight sensor for sensing the weight of an occupant in a vehicle seat, comprising:a) four substrates, each having a first and second end, one of the substrates mounted at each corner of the seat, the substrate mounted so as to be in a seat weight path between an upper slide rail and a seat pan; b) at least one strain gage resistor, located on the substrate, for generating an electrical signal in response to the substrate being stressed, the electrical signal changing as a function of the weight of the seat occupant; c) a plurality of wire harnesses, a wire harness electrically connected to each of the strain gage resistors; d) a junction box positioned under the seat, the wire harnesses electrically connected to the junction box; and e) a common wiring harness connected to the junction box, the common wiring harness adapted to be connected to an airbag controller, the common wiring harness providing the electrical signal to the airbag controller.
