Abstract
A hinge joint which pivotably connects the back to the weight carrying portion of a seat in a motor vehicle has a shaft with two concentric and two eccentric cylindrical portions. The component which is attached to the back has an internal gear mating with a spur gear of the component which is attached to the weight carrying portion of the seat. One of the components is rotatably mounted on the concentric cylindrical portions of the shaft, and the other component surrounds with a small clearance one of the eccentric cylindrical portions. The other eccentric cylindrical portion is surrounded by the prong-like segments of a diaphragm spring or by discrete segments to compensate for radial clearance between the mating teeth of the gears on the two components. Abutments are provided on the segments and/or on the other component to prevent tilting of the segments beyond positions of minimal inclination relative to the other component to thus ensure that each of the segments can be caused to change its inclination in response to engagement by the apex of the other eccentric cylindrical portion when the shaft is caused to turn in order to change, or to permit a change of, the inclination of the back relative to the weight carrying portion of the seat. The shaft need not move axially in response to turning about the common axis of its concentric cylindrical portions.
