An existing vehicle seat design is equipped with strain gauges welded to structural seat members to sense occupant seated weight. A microprocessor compensates for preload on the sensors and multiplies each signal by an empirically determined gain, and then combines the gauge outputs. The combined output is low pass filtered to avoid motion induced errors. The measured occupant seated weight is used by decision logic to decide whether to allow passenger airbag deployment.
