Proposed is a seat retainer in which first outer teeth and first inner teeth or second outer teeth and second inner teeth are engaged with each other at an angle, thereby a gap between a gear plate and a first flange or between the gear plate and a second flange can be removed.

An adjustment fitting for a vehicle seat for adjusting an inclination of a backrest of the vehicle seat may have a first fitting part connectable to a seat substructure of the vehicle seat. The fitting may also have a second fitting part pivotable about an axis relative to the first fitting part and connectable to the backrest of the vehicle seat. The first fitting part and the second fitting part may be constituent parts both of a gearing unit of the adjustment fitting and of a locking unit of the adjustment fitting.

A seat back assembly including a pultrusion reinforcement and a seat back frame formed of a resin material, the seat back frame is only partially overmolded onto the pultrusion reinforcement such that the pultrusion reinforcement is configured to be visually inspected through a plurality of openings formed in the seat back frame.

Proposed is a vehicle recliner including a mobile flange including a support part located in the center of a placement space and configured to protrude upwards from a lower surface thereof, the support part being formed in a multi-step structure having a different outer diameter for each step, a cam having a corresponding step formed thereon, the corresponding step corresponding to the multi-step structure of the support part, and a gear plate eccentrically pressed by the cam so that an external gear thereof meshes with an internal gear of the mobile flange.

A vehicle seat comprising a seat part, an adjustable backrest part attached to the seat part, and a floor assembly supporting the seat part and arranged on a vehicle floor. The seat part is connected to the floor assembly in a pivotal manner about a first axis, and the backrest part is connected to the seat part in a pivotal manner about a second axis. The vehicle seat has a first adjusting device powered by an electric motor for pivoting the seat part relative to the floor assembly about the first axis and a second adjusting device powered by an electric motor for pivoting the backrest part relative to the seat part about the second axis.

A vehicle seat comprises a seat part and a backrest, which are pivotally connected to each other via at least two swivel fittings, and the swivel fittings each have toothing rolling off on each other and are different in size.

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 a seat part, a backrest and a fitting of this type for setting an angle of inclination of the backrest is provided.

An automobile seat and an automobile comprising same, the automobile seat comprising a seat base, a seat back and a seat back adjusting mechanism; the seat back adjusting mechanism comprises a rotating part which is disposed at the lower end of the seat back; the rotating part rotates about the rear end part of the seat base to enable the angle between the seat back and the seat to be changed, and the center of rotation of the rotating part is located below the upper end surface of the seat base. A small step difference may be formed between the lower end part of the seat back and the upper end surface of the seat base when the seat back rotates, and a step difference may even be avoided. The lower end part of the seat back basically does not abut against and press the back of a passenger.

Disclosed is a vehicle seat locking device including: a single latch having an engaging groove and first through third arm portions; a ratchet having a restraining portion engaging the first and second arm portions, restraining the latch in first and second latching positions respectively; and an engagement auxiliary lever having a first auxiliary arm portion abutting with a leg portion of a striker and a second auxiliary arm portion pivoting by this abutment. The latch pivots from an unlatching position to the first latching position by engaging its engaging groove with the leg portion entered a striker entering groove of a baseplate, and pivots to a second latching position by the pivot of the second auxiliary arm portion. The leg portion exits the engaging groove by the pivot of the latch to the second latching position to be clamped between the engagement auxiliary lever and the third arm portion.

A recliner mechanism for a vehicle seat may include a guide plate, a locking plate, a pawl, an actuator hub, and a coil spring. The guide plate includes a recess and a projection. The locking plate includes a surface having teeth formed thereon. The pawl is movable in the recess between a secure position in which the pawl is engaged with the teeth of the locking plate to restrict relative rotation between the guide plate and the locking plate and a release position in which the pawl is disengaged from the teeth of the locking plate to allow relative rotation between the guide plate and the locking plate. Rotation of the actuator hub causes corresponding movement of the pawl between the secure position and the release position. The coil spring includes a first end engaging the actuator hub and a second end that hooks the projection of the guide plate.
