Open the CIPO recordAbstract From the Canadian patent
An inflatable band occupant restraint system includes an inflatable band that is configured to lower the stresses encountered by the band fabric during inflation and secondary impact. This reduction is accomplished by including a pleat pattern that better approximates the ideal cylindrical curvature of the band when inflated, attaching the band to a seat belt using a smaller radius attachment portion, and stitching the pleated portion of the band to the belt while maintaining the center of the band stitching-free.

Why it's free to use
- Filed July 8, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 8, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 8, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
