Open the CIPO recordAbstract From the Canadian patent
Universal health seat in which the peripheral edge of the top face of the sitting part (5) and the sitting face (4) are formed in such a way that the user thereof receives ideal support. The pelvis of the user is tilted into a correct position by a combination of the position of the recess (6) and the support of the thighs by the peripheral edge of the top face of the sitting part (5). The position of the pelvis affects the curvatures of the spine and consequently the sitting posture of the user. Back complaints are prevented in this way by the universal health seat.

Why it's free to use
- Filed July 16, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 16, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 16, 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.
