A sub-system test method for driver air bags has been established to quantify their dynamic restraint capability. The sub-system includes a driver airbag module as well as a steering wheel with rim supported. The test is called Driver Air Bag Linear Impactor Test – Dynamic (DABLIT-D). This test method can be used for not only A to B comparisons, but also for evaluating the performance of any DAB module design in general. A variety of impactor, pendulum and drop tower test methods are currently used at suppliers. DABLIT-D is aimed to standardize airbag testing. A DOE test series was done to determine the best test parameters. Production and prototype hardware were tested to investigate the characteristics of the sub-assemblies that provide restraint capability. A modification of the Weibull function was used to characterize the resultant data. The DABLIT-D test can also be used to assess the variability in the DAB modules, optimize inflator and airbag cushion designs, evaluate new venting technologies and calibrate CAE models.
