ABSTRACT:
The present invention is directed toward an vehicle airbag construction that reduces the incidence of an unrestrained passenger engaging the A-pillar during a high-speed crash. The present invention is also directed toward an airbag structure that reduces the risk of a restrained passenger's hands contacting the instrument panel. In accordance with the present invention, an airbag is formed so as to take on a generally hourglass shape when inflated. Thus, the inflated airbag of the present invention has a greater width dimension at the upper and lower ends thereof than at the middle. The enlarged width dimension at the airbag upper end prevents or minimizes contact between the passenger's head and the vehicle A-pillar. The enlarged width at the airbag lower end prevents or minimizes contact between the passenger's hands and the vehicle instrument panel.
