ABSTRACT:
The present invention relates to an airbag cushion that is lighter-weight, smaller, and more compact than the previously known airbag systems, yet still capable of providing a vehicle occupant with ample impact protection during a crash. Generally, the airbag comprises a one-piece woven cushion with two or more inflatable chambers. These chambers have a generally flat two-dimensional shape in its uninflated and unfolded configuration. However, once gas is added, the airbag cushion rapidly inflates and converts into a three-dimensional shape capable of providing impact protection to the occupant. Preferably, the three-dimensional configuration of the inflated airbag is generally triangular, V-shaped, or polygonal in shape. One of the inflatable chambers functions as an inflatable impact chamber configured such that when an inflation gas in infused into the airbag cushion during a vehicle crash, the inflatable impact chamber inflates and presents a surface to receive the impact of the body of a vehicle occupant. One of the other inflatable chambers is configured to comprise an inflatable support column that is in fluid communication with the inflatable impact chamber. The inflatable support column is constructed such that if inflatable impact chamber begins to compress or deflate under the stress of a crash, the inflatable support column provides a compression-resisting force to the inflatable impact chamber. Additional inflatable support columns may also be added.
