Passenger Air Bag Linear Impactor Dynamic Testing Method and Data Analysis

In order to quantify the dynamic restraint capability of a passenger airbag, a sub-system test method has been developed. The sub-system included a passenger airbag, an adjustable generic instrument panel (IP) and an adjustable windshield. The test was called the Passenger Air Bag Linear Impactor Test (PABLIT). This test method could be used for not only A to B comparisons, but also to evaluate the performance of any PAB module design in general, including performance variability of airbag systems. A variety of impactor, pendulum and drop tower test methods are currently used by inflatable restraint suppliers. PABLIT was aimed to standardize airbag testing and data analysis. Various production hardware designs were tested to investigate the characteristics of the sub-assemblies that provide restraint capability.

Vehicle to vehicle crash compatibility is becoming an increasingly more important consideration during vehicle safety development due to the increasing numbers of SUVs and pickups in the vehicle fleet. According to the Insurance Institute for Highway Safety (IIHS), their side impact crash test represents what happens when a passenger vehicle is struck by a pickup truck or SUV. The IIHS side impact test measures 37 different response criteria using an instrumented 5th percentile female SID-IIs ATD (anthropomorphic test device) in driver and left rear passenger seats. These measures are grouped into head and neck, torso, and pelvis and left leg regions. This paper will describe the development of transfer function equation models to assess the performance of design countermeasures by comparing the response measures of the torso region of the body.
