Open the CIPO recordAbstract From the Canadian patent
A suspension system for an automobile includes a compound torsion bar arrangement. The compound arrangement has a first bar which acts as a sway bar and a second bar which provides an output torque opposite to that of an input torque. The two bars are arranged to operate together and to be attached to the same location of respective wheel support structures. Variation of the torsional characteristics of the two bars of the compound arrangement allows the roll stiffness to be varied while also varying the forces which tend to lift the inside wheel when the automobile is moving in a curved path.

Why it's free to use
- Filed July 25, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 25, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 25, 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.
