Abstract From the Canadian patent

A seat adjuster comprising a system of linkages utilizing the effect of a compensating primary link which compensates for the normally uncompensated arcuate motion of the primary links. The links are attached to the riser, or the seat bottom and cooperate with each other in motion through the compensating link which is attached to the riser if the links are attached to the seat bottom and vice versa. The motion of the compensating link combines with the motion of the primary links to provide a substantially linear fore and aft motion to the seat.

Why it's free to use

  • Filed June 30, 1992 and granted May 19, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 30, 2012.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 30, 2014.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
