1. A method for correcting seat occupant weight measurement error induced by a seat belt comprising the steps of:

  • (a) measuring an occupant load applied to a vehicle seat;

    (b) determining the value of an asymmetrical load applied to the vehicle seat resulting from forces generated by securing an occupant to the seat with a seat belt by using data obtained during step (a);

    (c) determining a compensation factor if the asymmetrical load value load is greater than a minimum threshold; and

    (d) modifying the measured occupant load value by the compensation factor to obtain a corrected seat occupant weight value.
