  • Patent number: 11760235
    Abstract: 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.
