A hinge mounting for an adjustment device of a motor vehicle seat having a first external gear wheel comprising a first inner toothed surface and a second external gear wheel comprising a second inner toothed surface. At least two planet wheels mesh with both the first and second inner toothed surfaces. A driving toothed sun wheel meshes with the at least two planet wheels. At least one of the planet wheels has a ring-shaped spring forming the toothed surface of the plane wheel that is radially elastically deformable and permanently exert a force onto the sun wheel, the first inner toothed surface and the second inner toothed surface; and/or the sun wheel comprises a ring-shaped spring forming at least a portion of the toothed surface of the sun wheel and configured to be radially elastically deformable and permanently exert a force onto the planet wheels and bias these with force into abutment with the first and second inner toothed surfaces.
