Abstract
Sensors in a vehicle seat provide data for classifying occupants. Information from the sensors may be used to determine the position of an occupant relative to the seat and relative to the vehicle, the weight of the occupant, whether the seat belt is latched, and the position of the occupant relative to an airbag before and during a crash. Situations wherein airbag deployment is not desired are identified. A particularly inexpensive system meets the occupant classification needs of a system comprising a low risk deployment passenger airbag.
