Open the CIPO recordAbstract From the Canadian patent
A lightweight can assembly for housing and protecting the gas generator and inflatable bag of a passenger side restraint system includes a tether in the bag flush with the mouth of the can and at the center which retains the spreading forces at the mouth of the can upon bag deployment. This allows for a lighter section at the mouth of the can and eliminates the need for flanges along the sides of the can which flanges, would undesirably increase the envelope.

Why it's free to use
- Filed June 1, 1990 and granted April 28, 1992. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 1, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 1, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
