DEVELOPMENT AND TESTING OF AN AIRBAG AND ENERGY ABSORBING LAP BELT COMBINATION RESTRAINT SYSTEM

AN ENERGY-ABSORBING LAP BELT SYSTEM WAS DESIGNED TO BE USED IN CONJUNCTION WITH AN INFLATABLE RESTRAINT SYSTEM FOR PROTECTION OF THE FRONT PASSENGER OF A STANDARD-SIZE CAR. THE FORCE DEFLECTION CHARACTERISTICS OF THE BELT SYSTEM WERE DETERMINED ON THE BASIS OF ANALYTICAL SIMULATION OF OCCUPANT MOTIONS IN FRONT COLLISION, INCLUDING INTERACTIONS WITH THE INFLATABLE RESTRAINT SYSTEM AS WELL AS ON THE BASIS OF DYNAMIC TENSION TESTS OF ENERGY ABSORBING LAP BELT MATERIAL. FOUR IMPACT SLED TESTS AT 30 MPH WERE CONDUCTED USING THE COMBINED SYSTEM TO RESTRAIN A 50TH PERCENTILE DUMMY. TEST DATA INDICATED ACCEPTABLE PERFORMANCE DURING ALL FOUR IMPACTS. /AUTHOR/
