Abstract From the Canadian patent

A power actuator for automotive door latches. The actuator includes an electric motor mounted in a housing. A worm is operatively coupled to the motor for driving rotation of the worm about an axis in a first rotational direction. A worm gear which meshes with the worm, is mounted in the housing for rotation about an axis substantially orthogonal to the worm axis. A camshaft is mounted on the worm gear and has a rotation axis coincident with the gear axis. An output arm is affixed to the distal end of the camshaft for engaging the lever of a latch. The power actuator uses a reduced number of components.

Why it's free to use

  • Filed September 8, 2003 and granted September 20, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 8, 2023.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 8, 2025.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
