ABSTRACT:
An adjustable hinge for interconnecting the back part and seat part of a motor-vehicle seat has a fixed hinge element secured to the seat part and a movable hinge element secured to the back part. The movable hinge element is provided with a pinion having outer teeth centered on a movable axis and is further provided with a disk riveted with the pinion to the movable element and having an outer edge surface also centered on the movable axis. The fixed hinge element has a recess with a circular inner edge surface aligned radially with the outer edge surface of the disk and centered on a fixed axis spaced from the movable axis. Furthermore the fixed hinge element is formed with an array of inner teeth aligned with the outer teeth. The tooth depth is smaller than the spacing between the axes and there are fewer outer teeth than inner teeth. An eccentric ring carried on a handle has a circular outer periphery riding on the outer edge surface of the disk so that rotation of the handle orbits the movable axis about the fixed axis and adjusts the inclination between the hinge elements.
