Abstract
An inflator system that includes an inflatable and an inflator apparatus having a supplemental gas assembly is provided. The supplemental gas assembly supplies gas to the inflatable in order to maintain a desired inflatable volume and pressure for a relatively longer period of time. The inflator apparatus also includes a pyrotechnic inflator. The supplemental gas assembly and the pyrotechnic inflator can be activated at essentially the same time using the same initiator assembly. The supplemental gas assembly preferably has a stored gas that weighs less than 200 grams.
