The need has been recognized for automotive occupant restraint systems that are capable of sensing specific occupant, vehicle and crash attributes in a given crash. The sensed values of these variables form the basis for modifying the performance of seat belts and airbags, and the interaction between them when both are involved, in effectively restraining an occupant in a crash. Systems with these capabilities have been dubbed "intelligent" or "smart" systems. Four basic areas of development leading ultimately to the installation in vehicles of "intelligent" restraint systems are: (1) the characterization and implementation of sophisticated energy management in a crash event; (2) the development and development and application of suitable sensors; (3) the development and implementation of "smart" seat belt and airbag systems; and (4) the demonstration of the economic benefits to be realized through reduction of crash fatalities and serious injuries.
