Abstract
An outwardly deploying airbag system can maintain the internal pressure of an airbag for a required period without vainly increasing the maximum internal pressure of the airbag during inflation. When a sensor detects a collision with a pedestrian, an inflator performs a first gas injection step. An airbag is thereby deployed into a final deployment shape. Subsequently, when the internal pressure of the airbag falls to a predetermined pressure because of leakage of gas through vent holes, and a sensor predicts or detects a collision with a pedestrian, the inflator performs a second gas injection step. Consequently, the internal pressure of the airbag remains high for a long period, and the airbag sufficiently absorbs an impact whenever the pedestrian hits the airbag. The pressure and amount of gas injected in the first gas injection step can be made smaller than in related art, and the required airbag strength is reduced.
