ABSTRACT:
Inclination adjustment fitting for back rest of a vehicle seat includes first fitting part affixed to seat section, and second fitting part affixed to back rest, and which fitting parts are relatively pivotable around a pivoting axis. The two fitting parts include gearings forming components of a wobble gearing and roll on one another under influence of eccentric elements rotated around the pivoting axis. Eccentric element includes an eccentric ring, on which two wedge segments covering regions of eccentric ring lie in a mirror-image arrangement, and which are forced away from one another in the sense of an increase in eccentricity by a spring. Under excessive load, force transfer between fitting parts not accomplished via wedge segments; rather, a contact cam forming a single piece with eccentric ring projects into gap between end surfaces of wedge segments, transfers load via a contact surface from second fitting part first fitting part.
