Occupant weight detecting apparatus

An occupant weight detecting apparatus for detecting an occupant weight on a seat comprising:

• a load sensor mounted on the seat to detect a load on the seat and output a load signal;
• load calculating means for periodically calculating a detected load value based on the load signal;
• load delaying means for delaying the detected load value so that the delayed load value varies with a time lag following change of the detected load value when the detected load value is less than a first predetermined value;
• zero point setting means for setting the delayed load value delayed by the load delaying means to a zero point;
• and
• occupant weight detecting means for detect the occupant weight based on the detected load value and the zero point when the detected load value exceeds a second predetermined value.

• load calculating means for calculating a detected load value periodically based on the load signal;
• load delaying means for delaying the detected load value so that the delayed load value varies with a time lag following change of the detected load value when no occupant is on the seat;
• zero point setting means for setting the delayed load value delayed by the load delaying means to a zero point;
• and
• occupant weight detecting means for detect the occupant weight based on the detected load value and the zero point when the occupant is on the seat.
