Air Bag cushion having variable volume

摘要: An air bag cushion having variable volume. The includes a front wall central region for contacting the passenger, and periphery. This periphery is connected to of both an intermediate rear outer wall. Both these walls are operatively gas generator, but has larger area than generator provides initially inflate volume defined between wall, however, in manner which permits its release upon exceeding predetermined pressure within bag. Above this released inflates As such, if small amount produced, such as minor collision or due reduced ambient temperature, smaller inflated proper pressure. If greater generated, major increased provide
