ABSTRACT:
A thin plastic film is used to make the airbag of this invention. A preferred embodiment uses multiple thin film airbags which are inflated and confined to act together through the use of a surrounding net. In another embodiment, multiple layers of anisotropic film are joined together to form an airbag which is resistant to tearing. The inflator, which is typically of the aspirated type, fills the airbags through a manifold in a controlled sequence until each bag is filled to a specific pressure indicative of either being fully inflated or of interaction with an occupant.
