Samenvatting
The expected improved performance of a combined restraint system where an airbag supplements the conventional safety belt was not reflected in reduced G- values on the dummy's chest. However, by the distribution of forces over the wider area of the airbag and the corresponding reduction of the pressure exerted by the 3- point belt, improved occupant protection is actually produced.Therefore, a new method to measure the deflection of dummy ribs with strain gauges has been developed. The resulting data indicate a significantly reduced chest deflection when a combined system is used.
