Abstract
An inflator assembly for an airbag includes a container with a plurality of exhaust ports positioned about a perimeter. A rupturable, non-combustible material covers the perimeter of the container to cover the exhaust ports. A plurality of perforated and rupturable walls define a plurality of chambers concentrically disposed within the container. Within each of the plurality of chambers is a detonator to trigger a gas-producing chemical to inflate an airbag cushion. The detonators disposed in each of the individual chambers can be detonated separately from other detonators in other chambers.
