An adjusting device (1) for a motor vehicle interior component includes a housing (3) in which a rotational element (2) is provided in a rotatable manner about a rotation axis (100). A first locking element (21) is rotationally fixed to the rotational element (2), and a second locking element (22) is provided on the housing (3). The locking elements are reversibly movable relative to each other from a locked situation, in which the locking elements (21, 22) interact with each other in a positively and/or non-positively engaged manner, into an adjustment situation, in which said positive and/or non-positive engagement is released. The adjusting device has an adapter plate (23) which is provided in a rotatable manner relative to the rotational element (2) and the housing (3) and at least temporarily drives a locking element (21, 22).

To reduce an operation synchronization failure of recliners on both sides of a seat frame, thereby enabling smoother operation despite variations in the dimensional accuracy of the seat frame. A seat recliner structure includes: recliners which are provided on the left and right sides of a cushion frame and a back frame to recline the back frame relative to the cushion frame; and a connecting rod which connects the left and right recliners to synchronize them, wherein the left and right recliners have different backlashes, and the backlash of the driving-side recliner is smaller than the backlash of the driven-side recliner.

A long rail assembly attached to a vehicle floor for repositioning vehicle seats in a vehicle between a plurality of seating positions. The long rail assembly includes a fixed long rail having an internal channel, and a power rail drive assembly configured to travel along the channel of the fixed long rail. The power rail drive assembly has a rail main body having a lateral driving wheel configured to frictionally and/or meshingly engage with the fixed rail, an electric motor operatively coupled to the lateral driving wheel, and spring-loaded stability rolling elements attached to the rail main body configured to absorb channel variation as the power rail drive assembly travels along the channel of the long rail.

A seat and armrest assembly includes a seat including a frame having a movable element that is supported on the frame in a position. An armrest is supported on the frame and is movable relative to the seat between a first position and a second position. The armrest includes a locking pin that is disposed adjacent to the movable element of the frame to retain the armrest in the first position. A free play adjustment mechanism is provided to adjust the position of the movable element relative to the frame to minimize or eliminate space between the movable element and the locking pin. The free play adjustment mechanism includes an adjustment actuator having a threaded outer surface that cooperates with a correspondingly threaded inner surface of an aperture extending through the frame.

A longitudinal adjusting device for the motorized longitudinal adjustment of a motor vehicle seat may have a first rail and a second rail. The device may also have a spindle gearbox, a spindle cooperating with the spindle gearbox for the longitudinal adjustment, and a mount for receiving the spindle gearbox. The spindle gearbox may be at least partly held in the inner channel so as to be fixed relative to the first rail. Laterally projecting protrusions of the holding legs of the mount, which legs may be each arranged in front of and behind the spindle gearbox in the longitudinal direction, engage through lateral openings in the first rail. An abutment device having a contact section may be arranged in the region of the lateral openings. The contact section contacts the holding leg arranged in the particular opening. A vehicle seat with the device is also provided.

The invention relates to a device for attaching a seat assembly in a vehicle, wherein the device comprises a carriage and a floor rail, wherein the carriage can be fixed on the floor rail, wherein the floor rail has a longitudinal slot with a support section limiting the longitudinal slot, wherein a locking assembly having a locking element adjustably accommodated on the carriage is provided for fixing the carriage attached to the floor rail.
