An inflator for an air bag-type passenger restraint system for a motor vehicle includes two cup-shaped members which are joined to form chambers for a gas generator and activating devices for activating the gas generator. The two members are coupled by threads which do not increase the weight of the inflator. The inflator also includes a filter for filtering particulate matter from the gas generator.

Why it's free to use
- Filed July 9, 1992 and granted April 21, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 9, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 9, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
