Abstract

An occupant detection system comprises a weight sensor and an electric field sensor, each operatively coupled to a seat. The electric field sensor generates an electric field from at least one electrode in the seat bottom of the seat, provides for generating a response to an influence of the occupant thereupon, and is adapted to provide for discriminating from the response a seated infant or child seating condition from another seating condition. If a measure of weight from the weight sensor is less than a threshold, or if a seated child seating condition is detected by the electric field sensor, then a signal processor provides for disabling an associated restraint actuator. The electric field sensor may comprise a plurality of electrodes over separate first and second regions of differing proximity to a seated infant or child, or at least one electrode in cooperation with a shield or void over at least one of the regions.
