A door hinge pad (12) and body hinge pad (14) are respectively mounted on the door and body of an automotive vehicle, and interrelated for relative swinging movement by a pivot pin (16). A pair of spaced apart camming surfaces 30 integral with the door hinge pad (12) are resiliently tracked by first and second rollers (68) connected to opposite ends of a compression spring (66) integrally related to the body hinge pad (14). Swinging movement of the door hinge pad (12) away from the closed position moves the rollers (68) over a camming raised portion into a dwell (34) serving as a limit stop at a predetermined door opening angle.

Why it's free to use
- Filed June 30, 1999 and granted June 25, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 30, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 30, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
