Abstract

The invention relates to a fitting for a vehicle seat, especially for an automotive seat. Said fitting comprises two individual fittings (10, 50) that are arranged axially juxtaposed and in parallel in relation to the flow of force and that have at least two fitting parts (11, 12, 40, 51, 52) each that can be rotated in relation to each other, the inner fitting parts being interlinkable and the outer fitting parts being interlinkable. The invention is characterized in that one individual fitting is configured as an adjusting fitting (10) for adjusting the fitting (8) and the other individual fitting as locking fitting (50) for locking the fitting (8). Two fitting parts (11, 12) of the adjusting fitting (10) can be interlinked by means of a non-self-locking eccentric epicyclic gear. The locked locking fitting (50) bridges the adjusting fitting (10) in terms of the flow of force at least to a large extent.

Description

Beschlag für einen Fahrzeugsitz Fitting for a vehicle seat
Die Erfindung betrifft einen Beschlag für einen Fahrzeugsitz, insbesondere für einen Kraftfahrzeugsitz, mit den Merkmalen des Oberbegriffs des Anspruches 1.The invention relates to a fitting for a vehicle seat, in particular for a motor vehicle seat, having the features of the preamble of claim 1.
Aus der US 5,755,491 ist ein Beschlag dieser Art bekannt, bei dem ein Getriebebeschlag und ein Rastbeschlag bezüglich des Kraftflusses in Serie angeordnet sind. Der Getriebebeschlag dient der Neigungseinstellung einer Lehne, der Rastbeschlag zum Freischwenken derselben, d.h. um durch Vorschwenken der Lehne den Zugang zu einer hinteren Sitzreihe zu erleichtern. Der Getriebebeschlag kann prinzipiell motorisch angetrieben werden, während der Rastbeschlag hierfür ungeeignet ist.From US 5,755,491 a fitting of this type is known in which a geared fitting and a detent fitting with respect to the power flow are arranged in series. The gear fitting is used for the inclination adjustment of a backrest, the catch fitting for pivoting the same, i. to facilitate access to a rear row of seats by pivoting the backrest. The geared fitting can in principle be driven by a motor, while the catch fitting is unsuitable for this purpose.
Der Erfindung liegt die Aufgabe zu Grunde, einen Beschlag der eingangs genannten Art zu verbessern. Diese Aufgabe wird erfindungsgemäß durch einen Beschlag mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.The invention is based on the object to improve a fitting of the type mentioned. This object is achieved by a fitting with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.
Dadurch, dass der eine Einzelbeschlag als Justierbeschlag zum Verstellen des Beschlags und der andere Einzelbeschlag als Arretierbeschlag zum Feststellen des Beschlags ausgebildet ist, kann der Justierbeschlag hinsichtlich des Wirkungsgrades und der Arretierbeschlag hinsichtlich der Spielfreiheit und Crashlastaufhahme optimiert werden. Zur Verbesserung des Wirkungsgrades sind zwei Beschlagteile des Justierbeschlags mittels eines nicht-selbsthemmenden Exzenterumlaufgetriebes miteinander verbunden, d.h. der Justierbeschlag ist sehr leichtgängig, was sowohl bei einem manuellen als auch bei einem motorischen Antrieb vorteilhaft ist. Der arretierte Arretierbeschlag, welcher ein Rastbeschlag oder eine Bremse sein kann, überbrückt den Justierbeschlag bezüglich des Kraftflusses wenigstens weitgehend, vorzugsweise vollständig, d.h. der Justierbeschlag trägt allenfalls wenig zum Feststellen des Beschlags bei, beispielsweise aufgrund von Trägheitseffekten. Vorzugsweise ist ein Ausgleichsteil vorgesehen, welches eine taumelnde Bewegung der zwei Beschlagteile des Justierbeschlags ausgleichen und in eine gleichachsige Bewegung überführen kann, wie sie auch der Arretierbeschlag vollführt.The fact that the one single fitting is designed as adjustment fitting for adjusting the fitting and the other single fitting as a locking fitting for fixing the fitting, the Justierbeschlag can be optimized in terms of efficiency and the Arretierbeschlag in terms of backlash and Crashlastaufhahme. To improve the efficiency, two fitting parts of the Justierbeschlags are connected to each other by means of a non-self-locking eccentric revolving gear, ie the Justierbeschlag is very smooth, which is advantageous both in a manual and a motor drive. The locked locking fitting, which may be a detent fitting or a brake, bridges the Justierbeschlag with respect to the power flow at least largely, preferably completely, ie the Justierbeschlag contributes at most little to the detection of the fitting, for example due to inertial effects. Preferably, a compensation part is provided, which can compensate for a tumbling movement of the two fitting parts of the Justierbeschlags and convert into an equiaxial movement, as they also performs the Arretierbeschlag.
Bei einer bevorzugten Scheibenform der Beschlagteile kann der Beschlag auf einfache Weise als vormontierte Einheit geschaffen werden, wobei vorzugsweise eine - beispielsweise durch Lasergeschweißen erzeugte - Transportsicherung für eine erste Verbindung der Einzelbeschläge sorgt, die dann durch die Anbringung der Adapter gefestigt wird, wobei die an die Scheibenform angepasste Geometrie der Adapter sehr einfach gestaltet werden kann.In a preferred disc shape of the fitting parts of the fitting can be easily created as a preassembled unit, preferably one - for example, generated by laser welding - transport lock provides for a first connection of the individual fittings, which is then strengthened by the attachment of the adapter, wherein the attached to the Slice shape adapted geometry of the adapter can be made very simple.
Der erfindungsgemäße Beschlag wird bevorzugt zur Neigungseinstellung der Lehne verwendet, beispielsweise bei einem Einzelsitz, insbesondere Gurtintegralsitz, oder bei einer Rücksitzanlage mit geteilter (40% / 60%) Lehne in zweiter oder dritter Sitzreihe, kann aber auch anderweitig als Antrieb im Fahrzeugsitz eingesetzt werden, beispielsweise für einen Höheneinsteller oder Neigungseinsteller des Sitzkissens.The fitting of the invention is preferably used for tilt adjustment of the backrest, for example, in a single seat, especially seat belt integral seat, or in a rear seat system with divided (40% / 60%) back in second or third row of seats, but can also be used elsewhere as a drive in the vehicle seat, for example, for a height adjuster or tilt adjuster of the seat cushion.

Ein Fahrzeugsitz 1 eines Kraftfahrzeuges, der beispielsweise einen Teil einer Rücksitzanlage bildet, weist ein Sitzteil 3 und eine Lehne 4 auf, welche mittels einer Beschlagsanordnung 5 am Sitzteil angebracht und relativ zu diesem in ihrer Neigung einstellbar ist. Die Anordnung der Lehnenschwenkachse definiert als axiale Richtung das nachfolgend verwendete Zylinderkoordinatensystem. Die Beschlagsanordnung 5 umfasst wenigstens auf einer Fahrzeugsitzseite einen Beschlag 8. Der Beschlag 8 ist als Doppelbeschlag ausgebildet, d.h. er besteht aus zwei für sich prinzipiell voll funktionsfähigen Einzelbeschlägen, welche axial nebeneinander angeordnet sind. Die Einzelbeschläge sind ungleich ausgebildet und bezüglich des Kraftflusses alternativ zueinander angeordnet.A vehicle seat 1 of a motor vehicle, which forms, for example, a part of a rear seat system, has a seat part 3 and a backrest 4, which is attached by means of a fitting assembly 5 on the seat part and relative to this in its inclination adjustable. The arrangement of the Lehnenschwenkachse defined as the axial direction of the cylinder coordinate system used below. The fitting assembly 5 comprises at least on a vehicle seat side a fitting 8. The fitting 8 is designed as a double fitting, i. it consists of two in principle fully functional single fittings, which are arranged axially side by side. The individual fittings are uneven and arranged with respect to the power flow alternatively to each other.
Als erster Einzelbeschlag des Beschlags 8 ist jeweils ein Justierbeschlag 10 vorgesehen, welcher einen guten Wirkungsgrad für die Neigungseinstellung der Lehne 4 hat und daher dem Verstellen des Beschlags 8 dient. Dabei ist der Justierbeschlag 10 vorzugsweise für einen motorischen Antrieb ausgelegt. Der Justierbeschlag 10 weist ein erstes Justier-Beschlagteil 11 und ein zweites Justier-Beschlag- teil 12 auf, welche mittels eines als nicht-selbsthemmendes Exzenterumlaufgetriebe ausgebildeten Getriebes zum Verstellen miteinander verbunden sind. Die beiden Justier-Beschlagteile 11 und 12 weisen eine im wesentlichen flache Scheibenform auf. Zur Ausbildung des Getriebes ist am zweiten Justier-Beschlagteil 12 ein Zahnrad 16 mit einer Außenverzahnung und am ersten Justier-Beschlagteil 11 ein Zahnkranz 17 mit einer Innenverzahnung ausgeprägt, welche miteinander kämmen. Der Durchmesser des Kopfkreises der Außenverzahnung des Zahnrads 16 ist um wenigstens eine Zahnhöhe kleiner als der Durchmesser des Fußkreises der Innenverzahnung des Zahnkranzes 17. Der entsprechende Unterschied der Zähneanzahl von Zahnrad 16 und Zahnkranz 17 ermöglicht eine Abwälzbewegung des Zahnkranzes 17 relativ zum Zahnrad 16.As the first single fitting of the fitting 8 each Justierbeschlag 10 is provided, which has a good efficiency for the inclination adjustment of the backrest 4 and therefore serves to adjust the fitting 8. In this case, the Justierbeschlag 10 is preferably designed for a motor drive. The adjusting fitting 10 has a first adjusting fitting part 11 and a second adjusting fitting part 12, which are connected to one another by means of a gear designed as a non-self-locking eccentric planetary gear mechanism for adjusting. The two adjusting fitting parts 11 and 12 have a substantially flat disc shape. To form the transmission, a toothed wheel 16 with an outer toothing and the first adjusting fitting part 11, a toothed ring 17 is pronounced with an internal toothing on the second adjusting fitting part 12, which mesh with each other. The diameter of the tip circle of the external toothing of the toothed wheel 16 is smaller by at least one tooth height than the diameter of the root circle of the internal toothing of the ring gear 17. The corresponding difference in the number of teeth of gear 16 and ring gear 17 allows a rolling movement of the ring gear 17 relative to the gear 16th
Das erste Justier-Beschlagteil 11 weist auf der dem Zahnrad 16 zugewandten Seite konzentrisch zur Innenverzahnung des Zahnkranzes 17 einen angeformten Kragenzug 19 auf. Entsprechend der WO 03/024740 Al, deren Offenbarungsgehalt ausdrücklich einbezogen wird, ist ein Mitnehmer 21 vorgesehen. Der zweiteilig aufgebaute Mitnehmer 21 besteht aus einer Mitnehmerbuchse 21a, welche mit Luft in den Kragenzug 19 hineinragt und welche im Zentrum ein Innenprofil zur Aufnahme einer profilierten Antriebswelle 22 aufweist, und einem drehfest mit der Mitnehmerbuchse 21a verbundenen und außerhalb des Kragenzugs 19 angeordneten Mitnehmerring 21b. Der Mitnehmerring 21b definiert zusammen mit einem mondsichelförmigen Element, im folgenden kurz als Sichelelement 23 bezeichnet, einen Exzenter. Dabei wird das Sichelelement 23 in Umfangsrichtung von einem Mitnehmersegment 21c des Mitnehmerrings 21b mit Spiel gefasst. Der besagte Exzenter läuft durch eine Drehung der Antriebswelle (und damit des Mitnehmers 21) angetrieben in einer Gleitlagerbuchse 28 des zweiten Justier-Beschlagteils 12 um und bewirkt dadurch die relative Abwälzbewegung von Zahnkranz 17 und Zahnrad 16. Die Bewegung stellt sich als eine Relativdrehbewegung von erstem Justier-Beschlagteil 11 und zweitem Justier-Beschlagteil 12 mit überlagerter Taumelbewegung dar. Im Bereich der maximalen Exzentrizität stützt sich der Mitnehmerring 21b am Kragenzug 19 ab.The first adjusting fitting part 11 has on the gear 16 side facing concentric with the internal teeth of the ring gear 17 has a molded collar 19. According to WO 03/024740 Al, the disclosure of which is expressly incorporated, a driver 21 is provided. The two-part constructed driver 21 consists of a Mitnehmerbuchse 21a, which projects with air in the collar 19 and which has an inner profile for receiving a profiled drive shaft 22 in the center, and a non-rotatably connected to the Mitnehmerbuchse 21a and arranged outside of the collar 19 catch ring 21b. The driving ring 21b defines together with a crescent-shaped element, hereinafter referred to as sickle element 23, an eccentric. In this case, the sickle element 23 is taken in the circumferential direction of a driver segment 21c of the driver ring 21b with play. The said eccentric is driven by a rotation of the drive shaft (and thus of the driver 21) in a plain bearing bushing 28 of the second adjustment fitting part 12 and thereby causes the relative rolling movement of ring gear 17 and gear 16. The movement turns as a relative rotational movement of the former Justier fitting part 11 and second adjustment fitting part 12 with superimposed wobble. In the region of maximum eccentricity, the driving ring 21b is supported on the collar 19.
Für den axialen Zusammenhalt des Justierbeschlags 10 ist ein erster Umklammerungsring, im folgenden als Justierbeschlag-Ring 30 vorgesehen, welcher einerseits entlang des Außenumfangs des zweiten Justier-Beschlagteils 12 angeordnet und mit diesem verbunden ist, beispielsweise aufgepresst und gegebenenfalls laserverschweißt ist, und andererseits das erste Justier-Beschlagteil 11 übergreift.For the axial cohesion of the Justierbeschlags 10 is a first Umklammerungsring, hereinafter provided as Justierbeschlag ring 30, which is arranged on the one hand along the outer periphery of the second Justier fitting part 12 and connected thereto, for example, pressed and optionally laser welded, and on the other hand, the first Justier fitting part 11 overlaps.
Während die Mitnehmerbuchse 21a vorzugsweise aus Kunststoff gefertigt ist, bestehen die anderen Bauteile des Justierbeschlags 10 vorzugsweise aus Metall, beispielsweise Stahl, gegebenenfalls gesintert, gehärtet oder anderweitig behandelt. Alternativ zum beschriebenen Aufbau können der Mitnehmerring 21b und das Sichelelement 23 als Festexzenter einstückig miteinander ausgebildet sein. Es ist auch möglich, dass der gesamte Mitnehmer 21 einteilig ausgebildet ist, oder dass der Mitnehmer 21 und das Sichelelement 23 durch einen einteiliger Festexzenter ersetzt sind. Wenn das Sichelelement 23 durch zwei Keilsegmente entsprechend der WO 03/024740 Al ersetzt wird, ist der Justierbeschlag 10 im nicht-angetriebenen Ruhezustand spielfrei.While the drive bush 21a is preferably made of plastic, the other components of the Justierbeschlags 10 preferably made of metal, such as steel, optionally sintered, hardened or otherwise treated. As an alternative to the construction described, the driver ring 21b and the sickle element 23 can be integrally formed with each other as a fixed eccentric. It is also possible that the entire driver 21 is formed in one piece, or that the driver 21 and the sickle element 23 are replaced by a one-piece fixed eccentric. If the sickle element 23 is replaced by two wedge segments according to WO 03/024740 Al, the Justierbeschlag 10 is free of play in the non-driven resting state.
Am ersten Justier-Beschlagteil 11 ist auf der vom zweiten Justier-Beschlagteil 12 abgewandten Seite eine Außenverzahnung 37 vorgesehen, welche in einem gemeinsamen Prägevorgang zusammen mit dem Zahnkranz 17 ausgebildet wird. Ferner ist auf der vom zweiten Justier-Beschlagteil 12 abgewandten Seite des ersten Justier- Beschlagteils 11 als drittes Beschlagteil ein Ausgleichsteil 40 angeordnet, welches wie die beiden Justier-Beschlagteile 11 und 12 eine im wesentlichen flache Scheibenform aufweist und aus Stahl besteht. Das Ausgleichsteil 40 ist auf der dem ersten Beschlagteil 11 zugewandten Seite als Hohlrad 42 ausgebildet, d.h. mit einer entsprechenden Innenverzahnung versehen. Das Hohlrad 42 kämmt mit der Außenverzahnung 37, wobei der Fußkreis des Hohlrades 42 einen um wenigstens eine Zahnhöhe größeren Durchmesser als der Kopfkreis der Außenverzahnung 37 aufweist und die Anzahl der Zähne des Hohlrades 42 sich entsprechend von der Anzahl der Zähne der Außenverzahnung 37 unterscheidet.On the first adjusting fitting part 11, an external toothing 37 is provided on the side facing away from the second adjusting fitting part 12, which toothing is formed together with the toothed ring 17 in a common embossing process. Further, on the side facing away from the second adjustment fitting part 12 side of the first adjustment fitting part 11 as a third fitting part a compensation member 40 is arranged, which has like the two adjustment fitting parts 11 and 12 has a substantially flat disc shape and made of steel. The compensation part 40 is formed on the first fitting part 11 side facing as a ring gear 42, i. provided with a corresponding internal toothing. The ring gear 42 meshes with the external teeth 37, wherein the root circle of the ring gear 42 has a larger diameter by at least one tooth height than the tip circle of the external teeth 37 and the number of teeth of the ring gear 42 is correspondingly different from the number of teeth of the external teeth 37.
Das Ausgleichsteil 40 ist gleichachsig zum zweiten Justier-Beschlagteil 12 angeordnet, d.h. die Drehachsen fluchten miteinander, wobei der Durchmesser des Ausgleichsteils 40 vorzugsweise geringfügig kleiner ist als derjenige des zweiten Jus- tier-Beschlagteils 12, und wird - wie das erste Justier-Beschlagteil 11 - vom Justierbeschlag-Ring 30 übergriffen, wobei radial zwischen dem Ausgleichsteil 40 und dem Justierbeschlag-Ring 30 vorzugsweise noch ein Lagerring 44 angeordnet ist. Ein am Mitnehmer 21 angebrachter, vorzugsweise mit der Mitnehmerbuchse 21a verclipster Sicherungsring 45 dient als Sicherung für den Mitnehmer 21. Die genaue Ausbildung des Hohlrades 42 ist so gewählt, dass die Taumelbewegung des ersten Justier-Beschlagteils 11 relativ zum zweiten Justier-Beschlagteil 12 durch eine weitere Taumelbewegung des Ausgleichsteils 40 relativ zum ersten Justier-Be- schlagteil 11 ausgeglichen wird. Das Ausgleichsteil 40 beschreibt somit relativ zum zweiten Justier-Beschlagteil 12 eine reine Drehbewegung.The compensating part 40 is arranged coaxially to the second adjusting fitting part 12, ie the axes of rotation are aligned with each other, wherein the diameter of the compensating part 40 is preferably slightly smaller than that of the second adjusting fitting part 12, and - like the first adjusting fitting part 11 - Surpassed by Justierbeschlag ring 30, wherein radially between the compensation part 40 and the Justierbeschlag-ring 30 preferably still a bearing ring 44 is arranged. An attached to the driver 21, preferably verclipster with the drive sleeve 21a circlip 45 serves as a backup for the driver 21. The exact design of the ring gear 42 is selected so that the wobbling movement of the first adjustment fitting part 11 relative to the second adjustment fitting part 12 by a further wobbling movement of the compensating part 40 relative to the first adjusting fitting 11 is compensated. The compensating part 40 thus describes a pure rotational movement relative to the second adjusting fitting part 12.
Der Beschlag 8 weist als zweiten Einzelbeschlag einen Arretierbeschlag 50 auf, welcher dem Feststellen des Beschlags 8 in den verschiedenen Positionen der Lehne 4 dient, da der nicht-selbsthemmende Justierbeschlag 10 hierzu nichts beitragen kann. Der arretierte Arretierbeschlag 50 überbrückt den Justierbeschlag 10 bezüglich des Kraftflusses. Der geöffnete Arretierbeschlag 50 gewährt dem Justierbeschlag 10 die volle Bewegungsfreiheit und den vollen Kraftfluss während des Antriebs des Justierbeschlags 10. Diese "Wechselschaltung" ist zu unterscheiden von einer ständigen parallelen Anordnung bezüglich des Kraftflusses, wie sie für eine erhöhte Lastaufnahme bekannt ist, beispielsweise aus der DE 35 29 887 C2, und für Gurtintegralsitze dient.The fitting 8 has as a second single fitting a locking fitting 50, which serves to lock the fitting 8 in the various positions of the backrest 4, since the non-self-locking Justierbeschlag 10 can contribute anything this. The locked locking fitting 50 bridges the Justierbeschlag 10 with respect to the power flow. The open locking fitting 50 grants the adjustment fitting 10 the full freedom of movement and full power flow during the drive of the Justierbeschlags 10. This "change circuit" is to be distinguished from a constant parallel arrangement with respect to the power flow, as is known for increased load bearing, for example from DE 35 29 887 C2, and serves for Gurtintegralsitze.
Der Arretierbeschlag 50 ist als Rastbeschlag in einer Art ausgebildet, wie sie in der WO 00/44582 Al beschrieben ist, deren Offenbarungsgehalt ausdrücklich einbezogen wird. Der Arretierbeschlag 50 weist ein erstes Arretier-Beschlagteil 51 und ein zweites Arretier-Beschlagteil 52 mit jeweils einer im wesentlichen flachen Scheibenform auf. Das zweite Arretier-Beschlagteil 52 weist vier Führungs- und Lagersegmente zum radialen Führen zweier Riegel 53 und zum Lagern des ersten Arretier-Beschlagteils 51 auf. Das erste Arretier-Beschlagteil 51 weist entsprechend dem ersten Justier-Beschlagteil 11 einen Zahnkranz mit einer Innenverzahnung aus, mit welcher sowohl zum Verriegeln des Arretier-Beschlags 50 mit den Riegeln 53 zusammenwirkt also auch zur Lagerung auf den Führungs- und Lagersegmenten aufliegt. Die Riegel 53 werden durch einen federbelasteten, drehfest auf einem zweiten Mitnehmer 55 sitzenden zweiten Exzenter 56 radial nach außen zum Zahnkranz gedrückt und zum Entriegeln des Arretierbeschlags 50 durch eine Mitnehmerscheibe 57 radial nach innen gezogen. Die Mitnehmerscheibe 57 ist mittels des zweiten Exzenters 56 oder direkt mittels des zweiten Mitnehmers 55 aufgrund Betätigen eines außerhalb des Arretierbeschlags 50 angeordneten, auf den zweiten Mitnehmer 55 einwirkenden Hebels 59 drehbar. Analog zum Justierbeschlag-Ring 30 ist ein Arretierbeschlag-Ring 60 vorgesehen, welcher entlang des Außenumfangs des zweiten Arretier-Beschlagteils 52 angeordnet und mit diesem verbunden ist, beispielsweise aufgepresst ist, und andererseits das erste Arretier-Beschlagteil 51 übergreift.The locking fitting 50 is formed as a detent fitting in a manner as described in WO 00/44582 Al, the disclosure of which is expressly incorporated. The locking fitting 50 has a first locking fitting 51 and a second locking fitting 52 each having a substantially flat disc shape. The second locking fitting part 52 has four guide and bearing segments for radially guiding two latches 53 and for supporting the first locking fitting part 51. The first locking fitting part 51 has corresponding to the first adjustment fitting part 11 a sprocket with an internal toothing, with which cooperates both for locking the locking fitting 50 with the bolts 53 so rests for storage on the guide and bearing segments. The latch 53 are pressed by a spring-loaded, non-rotatably seated on a second driver 55 second eccentric 56 radially outward to the ring gear and pulled to unlock the Arretierbeschlags 50 by a drive plate 57 radially inward. The driver disk 57 is rotatable by means of the second eccentric 56 or directly by means of the second driver 55 due to actuation of a lever 59 arranged outside the arresting fitting 50 and acting on the second driver 55. Analogous to the adjustment fitting ring 30, a lock fitting ring 60 is provided, which is arranged along the outer periphery of the second locking fitting 52 and connected thereto, for example, is pressed, and on the other hand, the first locking fitting 51 engages over.
Je nach Anforderung, insbesondere dem zur Verfügung stehenden Bauraum und der Art des Antriebs, sind der Justierbeschlag 10 und der Arretierbeschlag 50 in bestimmter Orientierung zueinander ausgerichtet. Die "inneren Beschlagteile", beispielsweise das Ausgleichsteil 40 des Justierbeschlags 10 und das erste Beschlagteil 51 des Arretierbeschlags 50, sind einander zugewandt und miteinander verbunden, beispielsweise durch einzelne Schweißpunkte als Transportsicherung 63, während die "äußeren Beschlagteile", d.h. vorliegend das zweite Justier-Beschlagteil 12 und das zweite Arretier-Beschlagteil 52, voneinander abgewandt sind. Auf der Außenseite des zweiten Arretier-Beschlagteils 52 ist der Hebel 59 angeordnet, während auf der Außenseite des zweiten Justier-Beschlagteils 12 (oder innerhalb des Exzenters des Justierbeschlags 10) auf einem Motorträger 64 ein Elektromotor 65 mit einer Kupplung 67 angeordnet ist, welche die in den Mitnehmer 21 greifende Antriebswelle 22 antreibt. Ein Relais 69 steht mittels eines Seilzuges 71 in Verbindung mit dem Hebel 59.Depending on the requirements, in particular the available space and the nature of the drive, the Justierbeschlag 10 and the locking fitting 50 are aligned in a specific orientation to each other. The "inner fitting parts", for example the compensation part 40 of the Justierbeschlags 10 and the first fitting 51 of the locking fitting 50 are facing each other and connected to each other, for example, by individual welds as transport lock 63, while the "outer fittings", i. in the present case, the second adjusting fitting part 12 and the second locking fitting part 52, facing away from each other. On the outside of the second locking fitting 52, the lever 59 is arranged, while on the outside of the second adjusting fitting part 12 (or within the eccentric of the Justierbeschlags 10) on an engine mount 64, an electric motor 65 is arranged with a coupling 67 which the in the driver 21 cross drive shaft 22 drives. A relay 69 is connected by means of a cable 71 in connection with the lever 59th
Wenn die Neigung der Lehne 4 geändert werden soll, wird zunächst das Relais 69 betätigt, welches mittels des Hebels 59 den Arretierbeschlag 50 entriegelt und aktiv im entriegelten Zustand hält. Dann treibt der Elektromotor 65 den Justierbeschlag 10 an. Wenn die gewünschte Neigung erreicht ist, stoppt der Elektromotor 65, und das Relais 69 gibt den Hebel 59 frei, so dass der Arretierbeschlag 50 selbsttätig verriegeln kann. Um Stellungen "Zahn auf Zahn" aufzulösen, ist es möglich, dass sich der Elektromotor 65 vor dem endgültigen Stoppen geringfügig zurückdreht (oder weiterdreht), damit der Arretierbeschlag 50 um etwa eine halbe Zahnstellung verdreht wird und vollständig verriegeln kann.If the inclination of the back 4 is to be changed, the relay 69 is first actuated, which unlocks the locking fitting 50 by means of the lever 59 and actively holds in the unlocked state. Then, the electric motor 65 drives the Justierbeschlag 10. When the desired inclination is reached, the electric motor 65 stops, and the relay 69 releases the lever 59, so that the locking fitting 50 can lock automatically. In order to resolve "tooth to tooth" positions, it is possible for the electric motor 65 to slightly turn back (or continue to rotate) prior to final stoppage to allow the detent fitting 50 to be rotated about half the tooth position and fully locked.
In Notfällen, d.h. bei nicht vorhandenen Bordnetzspannung, beispielsweise wenn nach einem Unfall Insassen einer weiter hinten angeordneten Sitzreihe ohne eigene Türen aussteigen müssen, ist es für die Insassen möglich, den Arretierbeschlag 50 des davor angeordneten Fahrzeugsitzes 1 manuell zu entriegeln und durch Druck auf die Lehne 4 den Justierbeschlag 10 - unter Ausnutzung der fehlenden Selbsthemmung - manuell anzutreiben, so dass die Lehne 4 nach vorne schwenkt.In an emergency, ie in the absence of vehicle electrical system voltage, for example, if after an accident inmates a further back arranged row of seats without own Doors need to get off, it is possible for the occupants to unlock the locking fitting 50 of the front of the vehicle seat 1 manually and manually by pressure on the back 4 the Justierbeschlag 10 - taking advantage of the lack of self-locking - drive so that the back 4 pivots forward ,
Zur Anbindung des Beschlags 8 an das Sitzteil 3 einerseits und die Lehne 4 andererseits, sind ein erster äußerer Adapter 81, ein zweiter äußerer Adapter 82 und ein innerer Adapter 83 vorgesehen. Die beiden äußeren Adapter 81 und 82 weisen beide senkrecht zur axialen Richtung eine ebene Grundform mit je einem Lagerauge 85 auf, von der am Rand Verbindungslaschen 87 axial abstehen können. Vorliegend stehen vom ersten äußeren Adapter 81 zwei Verbindungslaschen 87 ab, vom zweiten äußeren Adapter 82 keine. Die beiden äußeren Adapter 81 und 82 sind mittels der Verbindungslaschen 87 miteinander unter Bildung eines Hohlkastens zu verbinden. Der innere Adapter 83 weist eine Gabel 89 mit einer halbkreisförmigen Aufnahme auf. Für spezielle Hochlastfälle kann der innere Adapter 83 radial über die Mitte des Beschlags 8 hinaus verlängert sein und anstelle der Gabel 89 ein ringförmig von Material umgebenes, weiteres Lagerauge aufweisen.To connect the fitting 8 to the seat part 3 on the one hand and the backrest 4 on the other hand, a first outer adapter 81, a second outer adapter 82 and an inner adapter 83 are provided. The two outer adapters 81 and 82 both have a plane basic shape, each with a bearing eye 85 perpendicular to the axial direction, from which connection tabs 87 can project axially at the edge. In the present case are from the first outer adapter 81 two connecting plates 87 from the second outer adapter 82 no. The two outer adapters 81 and 82 are to be connected to each other by means of the connecting plates 87 to form a hollow box. The inner adapter 83 has a fork 89 with a semicircular receptacle. For special high load cases, the inner adapter 83 may be extended radially beyond the middle of the fitting 8 and instead of the fork 89 have a ring-shaped surrounded by material, another bearing eye.
Zur Anbringung der Adapter 81, 82 und 83 wird der Beschlag 8 von der Gabel 89 des inneren Adapters 83 aufgenommen und sodann der innere Adapter 83 fest mit den "inneren Beschlagteilen" 40, 51 verbunden, vorzugsweise verschweißt, ganz besonders bevorzugt laserverschweißt. Dann werden die "äußeren Beschlagteile" 12, 52 mit den äußeren Adaptern 81 und 82 übergriffen, wobei vorzugsweise jeweils ein Absatz der "äußeren Beschlagteile" 12, 52 in je einem Lagerauge 85 zu liegen kommt, und schließlich die äußeren Adapter 81 und 82 direkt mit den jeweiligen "äußeren Beschlagteilen" 12, 52 und untereinander mittels der Verbindungslaschen 87 fest verbunden. Die Zuordnung zu Sitzteil 3 und Lehne 4 hängt vom Anwendungsfall ab. Die Verbindungslaschen 87 sind so weit von der Lehnen- schwenkachse angeordnet, dass der innere Adapter 83 beim Vorschwenken der Lehne 4 zwischen die äußeren Adapter 81 und 82 eintauchen kann. Besonders bevorzugt wegen der festen und daher guten Anbindungsmöglichkeit ist eine Anordnung von Justierbeschlag 10 und Arretierbeschlag 50, bei welcher der Justierbeschlag-Ring 30 und der Arretierbeschlag-Ring 60 mit den jeweils "inneren Beschlagteilen" verbunden sind, d.h. gemeinsam mit der Gabel 89 des inneren Adapters 83 verbunden werden können. To attach the adapters 81, 82 and 83, the fitting 8 is received by the fork 89 of the inner adapter 83 and then the inner adapter 83 is fixedly connected to the "inner fitting parts" 40, 51, preferably welded, most preferably laser welded. Then, the "outer fitting parts" 12, 52 are overlapped with the outer adapters 81 and 82, preferably each one shoulder of the "outer fitting parts" 12, 52 comes to lie in a respective bearing eye 85, and finally the outer adapters 81 and 82 directly with the respective "outer fitting parts" 12, 52 and with each other by means of the connecting plates 87 firmly connected. The assignment to seat part 3 and back 4 depends on the application. The connecting straps 87 are arranged so far from the backrest pivot axis that the inner adapter 83 can dip during the pivoting of the backrest 4 between the outer adapters 81 and 82. Particularly preferred because of the solid and therefore good connection possibility is an arrangement of Justierbeschlag 10 and Arretierbeschlag 50, wherein the Justierbeschlag ring 30 and the Arretierbeschlag ring 60 are connected to the respective "inner fittings", ie together with the fork 89 of the inner Adapters 83 can be connected.
