ABSTRACT:
An occupant sensor with a complex arrangement of antenna or a simple single antenna determines a charge or discharge characteristic of the antenna. By determining the change in voltage or current of the antenna as a function of time, any occupant may be detected or characterized. The sensor restricts air bag activation or is used for another purpose. The same or different occupant sensor is used for seat belt warnings. A seat belt latch sensor determines whether a seat belt is being used. The occupant sensor determines whether the seat belt should be used. A driver is warned when a seat belt should be used by an occupant, but is not.
