Research on the neck protective effect with airbag

The neck injury is usually ignored by researchers and regulations, but in fact the human neck injury is very serious and the rate of being disabled in the traffic accidents is very high.This paper focuses its study on the influence of different parts of the dummy loaded after the initiation of the airbag on the dummy's neck so as to protect the occupants better by changing the design of the airbag.Hybrid III dummy is used to evaluate the response of the occupant in the collision.Recently people are interested in the neck's response to airbag during the process of its loading.The biological force reaction of Hybrid III dummy's neck is based on inertia during the collision, when the dummy is constrained by the safety belt or the seat back.When the Hybrid III dummy is designed, the response caused by the airbag is not considered.This paper evaluates the effect of airbag loading on 5% female Hybrid III dummy.With experimental methods, this paper studies the different effects of different contacting parts when the initiation of the airbag loads on the dummy, focusing on the effect of 5% female Hybrid III dummy.It also illustrates some results that are changed by the experiment about the head / neck design of the 5% female hybrid III dummy preventing the airbag from trapping in.
