It has an outer shell mounted on a vehicle frame and an inner shell suspended on the inside of the outer shell. The outer shell peripheral wall is formed to provide some resiliency to cushion the inner shell. The suspension of the vehicle includes a trailing arm and a one-quarter elliptical spring biasing the trailing arm awayfrom the vehicle.

Why it's free to use
- Filed March 24, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 24, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 24, 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.
