Abstract

In one aspect, an apparatus for protecting an occupant of a vehicle includes an airbag having a stored condition in which the airbag is deflated, flattened, and rolled and/or folded. A packaging wrap is formed from a fabric sheet. The packaging wrap includes a cover and an elongated tail that extends from the cover. The cover is configured to be wrapped or folded about the rolled and/or folded airbag to envelope and package the airbag in the stored condition. The tail is configured to be wrapped around the cover and the airbag packaged therein to secure the airbag packaged in the cover.
