ABSTRACT:
A jointed fitting is described for vehicle seats comprising a planetary gear enabling the two fitting parts joined by a joint axle to be pivoted relative to each other, a second gear wheel (6) with an external toothing engages a first gear wheel (5) with an internal toothing. Both gear wheels (5, 6) have an involute toothing. Their teeth (7, 8) have a rounded-off head and the number of teeth of the second gear wheel (6) is slightly less than that of the first gear wheel (5). That point on the tooth flanks of the first gear wheel (5) at which the flank section extending along an involute passes into the flank section formed by the rounding-off of the head lies on a circle, the diameter (d.sub.el) of which is chosen so as to be at least approximately the same as the base circle diameter (d.sub.bl) of the first gear wheel (5). The top circle diameter (d.sub.al) of the first gear wheel (5) is smaller than its base circle diameter (d.sub.bl).
