1. An airbag comprising:
- an inflatable cushion made from a first material having an inflator opening to accommodate receipt of an inflator, the inflator having a longitudinal axis;
a baffle comprising a second material and a baffle opening, the baffle opening being aligned with at least one-third of the inflator opening and having an area that is approximately double the area of the inflator opening, wherein the baffle opening is present in the baffle before the airbag is filled with inflation gas from the inflator, and wherein upon inflation the inflator opening is visible when looking through the baffle opening in a direction parallel to the longitudinal axis of the inflator; and
a heat shield having the inflator opening to accommodate receipt of the inflator, the heat shield is made from a material different from that comprising the inflatable cushion.

Abstract
An airbag comprising a baffle and a heat shield. The baffle contains an opening, which is aligned with at least one-half of the inflator opening and having an area that is at minimum one-half of the area of the inflator opening. Inflation gas from an inflator flows into the baffle and then enters the airbag by way of the baffle opening. Because of the tortuous flow of the inflation gas inside the baffle, the hot particulates fall to the bottom of the baffle and thus never come into contact with the in flatable cushion.
