Abstract
A hinge mechanism for a vehicle seat, allowing adjustment of the tilt of a seat backrest relative to a seat cushion. The hinge mechanism has two plates, the first plate containing base gear teeth on an edge directed inward, a set of first elements cooperating with a first control cam biased by first springs, a set of second elements cooperating with a second control cam biased by second springs, and a control hub for moving the control cams toward an unlocking position against the biasing of the first and second springs. The set of first elements have teeth offset angularly by at most a half-tooth relative to teeth of the set of second elements, thereby obtaining a small locking pitch.
