Patent ID: 7211752

Claim:
A method for setting, by use of a plurality of dummies of different sizes, an inner pressure of a vehicular external airbag deployed along an outer surface of at least a front windshield of a vehicle, said method comprising: a first step of, when a small-size dummy of the plurality of dummies has collided against the vehicle and once a head of the small-size dummy hits the deployed airbag at a predetermined velocity, setting the inner pressure of the deployed external airbag to a characteristic such that the inner pressure takes a predetermined maximum level value capable of not only preventing the small-size dummy from bouncing off said external airbag but also preventing the head of the small-size dummy from hitting a bottom of said external airbag; and a second step of, when a medium-size dummy of the plurality of dummies collided against the vehicle, setting the inner pressure of the deployed external airbag to a characteristic such that the inner pressure decreases away from the predetermined maximum level value at a pre-determined decrease rate to prevent the medium-size dummy from bouncing off said external airbag.
