An airbag inflator system includes a housing defining a flow passage comprising a first end area and a second end area leading into an interior of an airbag connected to the housing. A reverse flow valve is arranged at the second end area and selectively enables connection of the flow passage to ambient atmosphere dependent on a pressure differential on opposite sides of the reverse flow valve. Anignition system supplies power to a gas generator component to induce gas generation. An aspirator component comprises an inlet part located beside the reverse flow valve and an aspiration part separated from the inlet part to define at least one opening surrounding the circumference of the flow passage. The aspirator part communicates with the gas generator component and faces the first end areaso that gas generated by the gas generator component flows to the flow passage and flows to the first end area via the opening.
