Fitting for an adjusting device of a motor vehicle seat and a method for the production thereof. The invention relates to a fitting (1), more particularly for an adjusting device of a motor vehicle seat, with a fitting top part and a fitting bottom part (3) adjustable relative to the fitting top part (2), a transmission gear unit, which is in operative connection with the fitting top part and fitting bottom part, for adjusting the fitting top part relative to the fitting bottom part, and a drive shaft (21) extending at one end through the fitting in a longitudinal axial direction of a fitting axis and in engagement with the gear unit. The invention also relates to a method for producing a fitting of the type mentioned above. To provide a fitting and a method for producing a fitting that ensures, even under elevated loads, a reliable arrangement of the fitting parts relative to one another, the invention provides wobble riveting the drive shaft (21) at one end to a bushing (6) to secure the axial position of the fitting top part (2) relative to the fitting bottom part (3), said bushing being arranged in an opening (11), arranged coaxially to the fitting axis, of the fitting top part or fitting bottom part, the drive shaft resting, on the side opposite the bushing, with a stop (12) against the fitting.

Die Erfindung betrifft einen Fahrzeugsitz mit einem scherenförmigen Schwingsystem und mit einer Vorrichtung zur Neigungs- und/oder Höhenverstellung der Sitzfläche. Es ist die Aufgabe gestellt, daß die Vorrichtung zur zur Neigungs- und/oder Höhenverstellung platzsparend sein muß und das Schwingsystem nicht beeinflussen darf. Vorgeschlagen werden Scherenlenker für das Schwingsystem, deren obere Lenkerteilstücke winkelverstellbar und fixierbar relativ zu dem verbleibenden unteren Teilstücken desselben Lenkers sind.

Fitting for an adjustment device of a motor vehicle seat. The invention relates to a fitting (1) for an adjustment device, in particular inclination adjustment of a motor vehicle seat, with a fitting upper part (2) having a first internal toothing (4), a fitting lower part (3) which is adjustable relative to the fitting upper part about a fitting axis and has a second internal toothing (5) arranged coaxially with respect to the first internal toothing, at least two, preferably, three, rotatably arranged planet gears (7) which are in engagement with the first and second internal toothings, and a drive shaft (6) which is in operative connection with the at least two planet gears by means of a pinion (23). In order to provide a fitting of the type mentioned at the beginning, in which noise loads and buckling effects are avoided even after a relatively long period of operation, a spring element (11) prestressing the planet gears (7) in the direction of the axis of rotation onto the fitting lower part (3) or fitting upper part (2) is provided.

Disclosed is a reclining mechanism comprising: a first plate (1) fixed to a seat back; a second plate (2) fixed to a seat cushion; a plurality of planetary gears (3) in meshing engagement with internal gears of the first and second plates; a sun gear (4) in meshing engagement with the planetary gears; and a holding member (5) rotatably holding the planetary gears. An inner peripheral wall of the holding member and an opposing wall section of the sun gear define therebetween a wedge-shaped space in which a restriction member (7) is displaceably disposed. The opposing wall section of the sun gear is formed such that a width of the wedge-shaped space is gradually narrowed toward a counter direction opposite to a specific direction along which the first plate is urged to be rotated according to a force applied to the seat back in a rearward tilting direction.
