DEVELOPMENT OF SIDE IMPACT AIRBAG SYSTEM USING FULL CAR SIDE IMPACT SIMULATION

D S Kim, M S Lee

Open publisher page 0 citations

Abstract

In order to reduce passenger injuries in side impact collisions, car makers are developing a side impact airbag system while a few car makers have already adopted the system. This study shows a simple SDM (sensing diagnostic algorithm) logic and examines effect of a side airbag system on dummy injury reduction using full car side impact simulation according to FMVSS 214 test procedure. The simulation result without side airbag shows a good correlation with test data. The developed SDM logic gives a reasonable firing time for triggering inflator. Through the side impact simulation with side airbag module integrated in the seat frame, it is found that the side airbag system provides a substantially enhanced protection for car occupants in side collisions. For the covering abstract see ITRD E116488.
