Abstract
A vehicle seat weight sensor for sensing the weight of an occupant in a vehicle seat. The sensor has a substrate that is attached between the ends of a seat bracket such that a portion of the forces applied to the seat are transferred from a seat pan to an upper slide rail through the substrate. Strain gage resistors are located on the substrate to generate an electrical signal in response to the substrate being stressed. The electrical signal changes magnitude as a function of the weight of the seat occupant. The substrate has a pair of step sections for concentrating the forces onto the strain gage resistor.
