Airbags are restraining safety devices aimed at reducing both mortality and morbidity from crashes, but their activation may sometimes produce an increase in the number of injuries when the vehicle occupant is very close to the airbag or in direct contact when it deploys. In fact, when this occurs, the force resulting from the energy released by the airbag can be stronger than claimed by the manufacturer. This kind of force is very important when the vehicle occupants are in different positions from those considered normal, called out-of-positions. For the Side Airbag and Curtain Airbag, there is already a protocol in place recommending procedures for assessing out-of-position injury risks through injury criteria.
