ABSTRACT:
An occupant weight sensing system includes a loading rod, which replaces a seat height adjuster pivot bolt and extends away from a seat height adjuster link. A sensing element is mounted at the opposing end of the loading rod. When force is applied the loading rod acts as a cantilever to transfer radial force to the sensing element. A plurality of strain gages are arranged down the center of the sensing element to provide a measurement of strain on the sensing element. The loading rod flexes to transfer any excessive force to a seat bracket. The sensing element has a low sensitivity to axial forces to avoid requiring additional mechanical components to protect the sensing element.
