Abstract
A vehicle seat weight sensing system includes a plurality of sensors mounted below a seating surface of a vehicle seat. Each sensor includes a tubular inner wall about which are coiled an activation coil and a detection coil. All of the weight of the seating surface is borne by the inner walls of the sensors. The activation coil induces a current in the tubular inner wall which is detected by the detection coil. Stress in the inner wall alters the signal detected by the detection coil. Analysis of the wave form of the signal indicates the amount of stress applied to the tubular inner wall and the weight upon the vehicle seating surface. A fastener connecting to vehicle seat components passes through the tubular inner wall and retains the sensors in the vehicle seat.
