Patent number: 11760235Abstract: A fitting for a vehicle seat may have a first ring gear having first ring gear teeth, a second ring gear having second ring gear teeth, and a planet gear mounted on a planet carrier and which meshes with the first and second ring gear teeth. A blocking planet gear, which can be rotated about a blocking-planet-gear axis of rotation, permanently meshes with the first ring gear teeth and with the second ring gear teeth, and the distance between the blocking-planet-gear axis of rotation and the axis can be changed so that the blocking planet gear can be transferred selectively between locking meshing and non-locking meshing with the first ring gear teeth and/or with the second ring gear teeth. A vehicle seat having a seat part, a backrest and a fitting of this type for setting an angle of inclination of the backrest is provided.Type: GrantFiled: October 26, 2020Date of Patent: September 19, 2023Assignee: Keiper Seating Mechanisms Co., Ltd.Inventors: Kirubaharan Albert, Grit Scholz, Daniel Huebner, Dieter Henkel, Balaji Paramasivam, Arkadius Rock, Rolf Schueler, Mothanna Yasen, Thomas Dill, Christian Wolf

Patent number: 9303685Abstract: A fitting for a vehicle seat, such as a motor vehicle seat, includes a first fitting part, on which a ring gear is formed, and a second fitting part, on which a spur gear is formed, which meshes with the ring gear. The two fitting parts are in transmission connection with each other. A rotatably supported eccentric rotates in the circumferential direction for driving a relative rolling motion of the spur gear and the ring gear. The outside of the eccentric is arranged in a plain bearing bushing in the radial direction. The plain bearing bushing is arranged in a bearing seat, such as a collar of the first or second fitting part. The plain bearing bushing has a wall thickness of less than 1 mm and is connected to the bearing seat in a bonded manner by laser welding. A running side of the plain bearing bushing is plastic-coated.Type: GrantFiled: October 23, 2012Date of Patent: April 5, 2016Assignee: KEIPER GMBH & CO. KGInventor: Grit Scholz
