GONFIATORE A DUE STADI CON MODULO DI SFIATO PER CUSCINI D'ARIA LATO PASSEGGERO

A passive two stage passenger side inflator is disposed in a module funnel coupled to an airbag. The two stage inflator provides a gentle onset during the initial deployment to help protect out-of-position passengers. The second rapid stage is ignited passively by hot gas communication from the first stage. The inflating gases from both stages flow through a module funnel into the airbag. Openings in the module funnel permit pressure relief venting of the airbag to further protect out-of-position passengers even if the bag has not yet unfolded. Preferably the module is mounted such that the funnel vent openings direct the vented gas into the instrument panel, thus minimizing the particulate released into the passenger compartment.
