Open the CIPO recordAbstract From the Canadian patent
A composite air bag assembly door is disclosed comprising, an outer-surface layer, a flexible polyurethane foam layer and a structural support. The polyurethane foam used in the door was designed to withstand the high tensile and tear forces generated by deployment of the air bag. The cohesive strength of the foam acts as a bonding agent between the surfacing film or film and the structural support or substrate helping to ensure that the door remains intact.

Why it's free to use
- Filed September 1, 1993 and granted August 17, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 1, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 1, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
