Abstract: A hinge fitting for motor vehicle seats having an adjustable backrest comprises a fixed hinge member, which is associated with the seat, and a swivelling hinge member which is associated with the backrest. The two hinge members are connected via an eccentric so as to swivel, and both hinge members comprise sets of toothing which engage with each other and form part of a wobble mechanism. In this regard, the eccentric may be swivelled about a first swivelling axis in a first pivot bearing relative to one hinge member and about a second swivelling axis in a second pivot bearing relative to the other hinge member. Both pivot bearings are arranged eccentrically relative to each other.      The pivot bearings are formed by plain bearing bushes which are mounted in the hinge members. For the purpose of calibration by means of a calibrating mandrel, the plain bearing bushes are plastically compressible. The running surfaces of the plain bearing bushes observe the, in each case, smallest spacing from the associated axis of the hinge member which accommodates the respective plain bearing bush. The hinge fitting has an only small overall width and has a high internal stability, even against high forces such as may arise during accidents. In addition, the hinge fitting has extremely small bearing clearances which are obtained with simple manufacturing methods.
