<p>A hinge joint for adjustment of the angle of inclination of the backrest of a seat, particularly in motor vehicles, with a stationary articulated hinge lever and a pivotable articulated hinge lever, which articulated levers are pivotably mounted with respect to each other about a common axle by means of a handle, and each articulated lever has an inner gear rim on their sides facing one another. The inner gear rims have the same root base and gear tip diameters and jointly mesh in engagement with only a single disc comprising a toothed disc, the latter being rotatably mounted on an eccentric and movable in eccentric translation with the eccentric about the common axis of the two articulated hinge levers. One of the inner gear rims has at least one tooth less than that of the other inner gear rim, and the toothed disc has at least one tooth less than that of the inner gear rim with the smaller number of teeth.</p> |
