Patent Images
1. An occupant-detecting apparatus, comprising:
- a plurality of load sensing devices each configured to detect a load imparted on a vehicle seat; and
an occupant-sitting determination device configured to determine whether or not an occupant is seated on the vehicle seat based on detected loads of the load sensing devices,said load sensing devices being configured to detect loads at a plurality of different positions on the vehicle seat, andsaid occupant-sitting determination device being configured to determine whether to perform an occupant-sitting determination based on a comparison between a predetermined threshold value and an absolute value of a variable amount between a sum of previously-collected load sample values and a sum of presently-collected load sample values detected by the load sensing devices.

Abstract
An occupant-detecting apparatus includes a plurality of load sensors configured to detect a load imparted on a vehicle seat, and an occupant-sitting determination device configured to determine whether or not an occupant is seated on the vehicle seat, based on detected result of the load sensors. The load sensors are configured to detect loads at different positions on the vehicle seat, and the occupant-sitting determination device is configured not to perform occupant-sitting determination if an absolute value (ΔW) of a variable amount in a sum of detected result of the load sensors is lesser than a predetermined threshold value (TH/L).
