PERFORMANCE EVALUATION OF AUTOMOBILE HEAD RESTRAINTS

ACCIDENT CASES INVOLVING CARS WITHOUT HEAD RESTRAINTS ARE COMPARED WITH CARS HAVING THIS DEVICE TO EVALUATE THE EFFECTIVENESS OF HEAD RESTRAINTS, THEIR POSITION WHEN IMPACT OCCURRED, AND TO PROVIDE SOME DETAILS CONCERNING THE RELATIONSHIP BETWEEN OCCUPANT POSITION, SEAT BACK DAMAGE, AND CERVICAL INJURY. A REDUCTION IN NON-DANGEROUS CERVICAL INJURY WAS ASSOCIATED WITH THE HEAD RESTRAINT GROUP. HOWEVER, DUE TO SMALL NUMBERS THIS COULD NOT BE CONFIRMED, STATISTICALLY. APPROXIMATELY 73% OF THE ADJUSTABLE HEAD RESTS WERE IN THEIR LOWEST POSITION. THE POSITION OF THE OCCUPANT ON THE SEAT BACK WAS ASSOCIATED WITH LOWER INJURY SEVERITY. /HSL/
