ABSTRACT:
Articulated fitting for seats having an adjustable backrest, in particular motor vehicle seats. The articulated fitting arranged on each longitudinal side of a seat has a stationary articulated part associated with the seat part and a swivelable articulated part associated with the backrest, these articulated parts being connected with one another via a swivel axle. The position of the two articulated parts relative to one another is determined by an adjusting and fixing device constructed as a gear unit. The swivel axle has an eccentric portion for supporting one articulated part and the swivel axle of each articulated fitting has a central receptacle serving to connect with a transmission rod so as to be fixed with respect to rotation relative thereto, which transmission rod couples the two articulated fittings of a seat with one another. In order to eliminate faulty assembly by means of determining visually whether or not the angular positions of the articulated parts of the two articulated fittings conform to one another, these articulated parts being connectable with the backrest, the transmission rod and the recess of the swivel axle which receives the transmission rod so as to be fixed with respect to rotation relative thereto have a profile cross section in the shape of a polygonal or toothed circumference having a missing corner or tooth, as the case may be, at a location on the circumference, this location being reduced to the core cross section of the transmission rod so that the transmission rod may be inserted into the recess of the swivel axle after a complete revolution of 360 degrees.
