ABSTRACT:
A hinge mount assembly for motor vehicle seats includes at each lateral side of the seat an outer hinge mount member shaped with an embossed external gear meshing at one point with the internal gear. Both hinge mount members are supported on a rotary axle having an eccentric portion supporting the inner hinge mount member and thus forming a wobble gear inclination adjuster for the backrest. The axial compactness of both hinge mount assemblies of the seat is insured by bearing plates adjoining the inner hinge mount members and being interconnected above the pivot axle by a U-shaped attachment frame for the backrest and, below the pivot axle, by a transverse beam. In addition, each inner hinge mount member is rigidly connected to a reinforcing side strap which overlaps the outer surface of the outer hinge mount member.
