Open the CIPO recordAbstract From the Canadian patent
An armature (1) for a motor-vehicle steering wheel. The hub (2), spokes (3), and rim (4) are at least partly made out of a single sheet of metal. The metal is folded at the edge (10) to produce a cross-section in the form of a U or L. The base (5) of the section is essentially perpendicular to the axis of the steering wheel. The sides (6, 7, 8) of the section essentially parallel that axis. The sides of the U or L are provided with an undulation as viewed longitudinally, that is almost non-existent in the vicinity (9) of the base, and that increases continuously to a maximum as it approaches the edge (10).

Why it's free to use
- Filed August 8, 1997 and granted October 2, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 8, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 8, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
