A new crash mode will be introduced in the North American market If the existing 56kph frontal crashworthiness was one of the most important challenges for the manufacturer, the 90kph 15 ° inclined 35% overlap collision is an issue in the future. Major injuries that occurred during frontal collision were head acceleration and neck injury, while in new mode, head rotation and neck injury were major injuries. This is to protect passengers in actual crash mode based on actual accident investigation.
In addition to the new crash mode, the use of new mode makes it difficult to satisfy passenger injuries with the characteristics of existing airbags. Accordingly, various tasks are being performed by the manufacturers of passive safety systems. Especially, the pressure and performance of PAB are very important because the THOR dummy located in RH side is greatly influenced by PAB performance. In this paper, we analyze the passenger Movement of the RH side and improve the injury through the airbag performance. The thor dummy of the far side is of interest in the left-leaning collision.
Plus, North America regulations must also satisfy LRD testing with the same inflator and cushion. In this paper, I propose improvement of airbag which can satisfy both BRIC injury and LRD performance which are main items of OMDB crash test. Especially, we will seek improvement through the inflator optimization and new concept of cushion which is the most important factor of the passenger airbag
