Abstract:
A vehicle seat weight sensor for sensing the weight of an occupant in a vehicle seat, the seat having an upper and a lower slide rail, a seat pan, a seat back and a seat bottom, the sensor comprising:a) at least one seat bracket having a first and second end, the seat bracket located between the seat pan and the upper slide rail;a) a substrate attached substantially diagonally between the first and second ends of the bracket such that a portion of force applied to the seat bottom is transferred from the seat pan to the upper slide rail through the substrate;b) a plurality of strain gauge resistors, 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; andc) a plurality of fasteners, located at the first and second ends of the bracket, for attaching the substrate to the seat bracket.
