Abstract
A multi-chambered airbag is sewn in a flat or 2-D state. The airbag includes a first fabric panel, a second fabric panel of a shape similar to the first fabric panel and coupled to at least a portion of a periphery of the first fabric panel, and a separator panel coupled to the first and second fabric panels. The separator panel forms two or more interior chambers in the airbag. The separator panel includes a venting mechanism to temporarily block the flow of inflation gases into one or more chambers in the airbag or to the outside.
