This paper reports on the National Highway Traffic Safety Administration’s (NHTSA’s) research program on Advanced Air Bag Technology. This program was initiated to establish the technical basis for new vehicle performance requirementsf or improved occupantc rashp rotection. The primary tasks include: real-world crash investigations, development and certification of test dummies and associated injury criteria, evaluation of advanced air bag technology, and development of test procedures. NHTSA also has initiated cooperative research programs with NASA/Jet Propulsion Laboratory and Transport Canada, and is gathering information and data through the Motor Vehicle Safety Research Advisory Committee (MVSRAC). Research work will be used to support rulemaking activities on advanced air bag systems, This paper presents an overview of this effort.
