A seat for use in a motor vehicle has a body supporting unit and a back rest which is pivotably connected to the body supporting unit by two hinges having pintles provided with eccentrics which cause the back rest to perform a composite pivotal and transverse movement while it changes its orientation with reference to the body supporting unit. The back rest carries two pivotably mounted arm rests which are connected to the back rest and to the body supporting unit by linkages serving to ensure that the orientation of the arm rests remains substantially or completely unchanged while the back rest is pivoted with reference to the body supporting unit. A second linkage can be used to pivot the front ends of the arm rests rearwardly and upwardly when the back rest is lifted with reference to the body supporting unit and is pivoted forwardly toward the dashboard in a two-door motor vehicle in order to afford convenient access to the rear seats or to permit a passenger to leave a rear seat with a minimum of effort.

Seat with adjustable back and arm rests

A hinge has two hinge parts pivotally connected with one another and an adjusting and fixing device including interengaging external and internal gears, wherein each gear has an annular groove formed by deformation in the region of its teeth root circle so that during formation of the annular groove the material is displaced toward the teeth tips of the respective gear.

Hinge, particularly for seat with adjustable back rest and method of

A swivel joint, especially for seats with an adjustable back rest, comprises two link members connected to each other by a pivot pin and a device for angularly adjusting the two link members with respect to each other and for holding the same in any adjusted position and comprising an internal spur integral with one link member and meshing with a spur gear integral with the other link member in which one of the gears is mounted on an eccentric portion of a pivot pin, wherein at least one and preferably both gears are provided at the base lands thereof with elastic buffer elements for compensating tolerances and for eliminating noise.
