Abstract
A vehicle includes a pair of frame rails and a bumper assembly. The bumper assembly includes a bumper beam supported by the frame rails and an airbag. The airbag includes a first airbag chamber supported by the bumper beam and inflatable to an inflated position, and a second airbag chamber supported by the bumper and inflatable to an inflated position. The first airbag chamber is disposed in a cross-vehicle direction relative to the second airbag chamber. The first airbag chamber has a first volume in the inflated position. The second airbag chamber has a second volume in the inflated position. The first volume is different than the second volume.
