Abstract: The adjustable hinge mount for motor vehicle seats having a reclinable seat back comprises means for holding respective hinge members of the mount in a fixed axial position. The holding means comprises a bearing shield supported for rotation on the rotary axle interconnecting the two hinge members. The rim portions of the shield above the rotary axle and on the level of the latter are connected to the outer hinge member assigned to the seat back in such a manner that substantially no axial play takes place. The lower range of the outer hinge member is secured against axial play by means of a Z-shaped guiding plate integrally connected to the hinge member assigned to the seat proper.

Abstract: A knob is used on an adjustment member rotatable about an axis and having a periphery formed with a plurality of radially outwardly open recesses. This member may be the adjustment member of a motor-vehicle seat-angle adjuster. The knob comprises an annular collar closely surrounding the periphery of the adjustment member, a plurality of entrainment formations projecting inwardly from the collar into every other recess, and a plurality of hooks each engaging axially through the remaining recesses with the member. The hooks and the formations together transmit angular force between the member and the knob which is made of synthetic-resin material as one integral piece.
