Open the CIPO recordAbstract From the Canadian patent
A fastener bolt for an automobile seat belt anchor is provided with an annular energy-absorbing cushion on the front surface of the bolt head. In a crash situation, forcible movement of a vehicle occupant's head against the cushion will have a lessened tendency to cause human injury or pain. The annular cushion has a central access opening that registers with a non-circular cavity in the bolt head, such that the fastener bolt can be screwed into a hidden fastener nut while the cushion is in place on the bolt.

Why it's free to use
- Filed January 5, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 5, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 5, 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.
