  • Seat foam humidity compensation for vehicle seat occupant weight detection system
    Patent number: 6818842
    Abstract: A vehicle seat occupant classification system uses a pressure responsive, fluid filled bladder and pressure sensor adapted for engagement with an underside of a foam seat cushion so as to generate a pressure signal corresponding to the weight of an occupant on an upper side of the foam seat cushion. A humidity sensor responds to relative humidity of air adjacent the pressure sensor and/or foam seat cushion to generate a humidity signal that is used to compensate at least one of the pressure signal, a stored reference pressure value and a stored threshold value, from which at least in part; an occupant classification is determined.
    Type: Grant
