Abstract

The mechanism consists of base (6) fitted to the car floor with two seatings for lateral rods. One of the rods (9) has a set of levers (3) welded onto it, with toothed segment (7). The other rod (11) is fitted on the end of lever (5) with its other end seated on the base. The second lever (3) also has a toothed segment (7). Both segments are in mesh with gears (8) fitted on servomotors. The geometrical arrangement of the lever assemblies is such that, when both servomotors are simultaneously operated, the seat top performs a movement in horizontal direction. If only one servomotor is operated, the tilt of the seat is changed.

Description

"Höhen- und neigungsverstellbarer Kraftwagensitz" "Height and tilt adjustable vehicle seat"

Die Erfindung betrifft einen höhen- und neigungsverstellbare Kraftwagensitz, wobei die Verstellbewegungen durch unterhalb des Sitzkissens angeordnete Servomotoren ausgelöst und in eine zugeorndete Hebwlanordnung eingeleitete werden, die zwischen fahrzeugfesten Konsolen und mit Sitzfährungsschienen in Verbindung stehenden Lagerstellen angeordnet ist, und wobei durch in Fahrzeugquerrichtung verlaufende Wellen eine Ubertragung der Stellbewegungen erfolgt.The invention relates to a height and tilt adjustable motor vehicle seat, the adjustment movements by servomotors arranged below the seat cushion triggered and introduced into an assigned Hebwlan arrangement, which between Consoles fixed to the vehicle and bearing points connected with seat rails is arranged, and wherein a shaft extending in the vehicle transverse direction The actuating movements are transmitted.

Eine derartige Anordnung ist durch die US-PS 2 839 124 bekannt wobei als nachteilig anzusehen ist, daß wegen bid w@@@ unter die Sitzfläche reichenden aufwendigen Übertragungs- und Antriebselemente kein Platz mehr für die Verlegung von Leitungen oder Heizkanälen bleibt.Such an arrangement is known from US Pat. No. 2,839,124 wherein is to be regarded as disadvantageous that because of bid w @@@ reaching under the seat complex transmission and drive elements no longer have space for laying of pipes or heating ducts remains.

Es ist Aufgabe der Erfindung, unter Verwendung einfacil aufgebauter und platgünstig angeordneter Elemente einen höhen-und neigungsverstellbaren Kraftwagensitz schaffen, der als vormontierte Baueinheit auch in Kraftfahrzeuge einsatzbe ist, bei deiien unterhalb des Sitzkissens Vcrsorgungs lej tungen und/oder Luftzuführungskanäle verlaufen.It is the object of the invention to use a simple structure and elements arranged in a space-saving manner a height and tilt adjustable motor vehicle seat create that can also be used as a pre-assembled unit in motor vehicles, for the supply lines and / or air supply ducts below the seat cushion get lost.

Deshalb wird höhe- und neigungsverstellbarer Kraftwagensitz der eingangs genanten Art vorgeschlagen, wobei erfiridungsgemäß die Hebelanordnung aus paarweise angeordneten Laschen besteht, die sich vorzugsweise an der Sitzkissenvorderseite zusätzlich über Streben an der Konsole abstützen, und wobei die laschen einer Seite über die Lagerstellen hinaus verlängert sind und ein Zahnsegment tragen, das mit einem antreibsseitigen Ritzel kämmt.That is why the vehicle seat is adjustable in height and inclination the initially mentioned type proposed, according to the invention, the lever arrangement from There are tabs arranged in pairs, which are preferably located on the front of the seat cushion In addition, support it via struts on the console, and with the tabs on one side are extended beyond the bearings and carry a toothed segment that with meshes with a drive-side pinion.

Auf diese Weise werden die /ritriebs- und Verstellelemente in Konsolennähe angeordnet, wobei zur besseren Raumnusnutzung Antrieb und Getriebe - verbunden durch eiiic flexible zelle -voneinander entfern plaziert sein können.In this way, the drive and adjustment elements are close to the console arranged, whereby for better use of space drive and gear - connected by A flexible cell can be placed at a distance from one another.

Bei inem bevorzugten Ausführungsbeispiel der Erfindung umgreifen die Laschen die konsolen- bzw. strebenseitige Lagerstelle gabelförmig und die einander zugekehrten Gabelschnitte si'..-d durch eine felle miteinander verbunden. Dadurch ergibt sich neben einer erheblichen Versteifung auch eine günstige Übertragung der Stellbewegungen von der Antriebsseite zu der dieser abgewandten Seite.In a preferred embodiment of the invention, the encompass Tabs the bracket or strut-side bearing point fork-shaped and each other facing fork cuts are connected to one another by a skin. Through this In addition to a considerable stiffening, there is also a favorable transmission of the Adjusting movements from the drive side to the side facing away from it.

Der Gegenstand der Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.The subject matter of the invention is explained below with reference to one in Drawing illustrated embodiment explained in more detail.

Liia nicht näher dargestellter Kraftwagensitz, der durch Sitzführungsschienen 1 in Fahrzeuglängsrichtung verschiebbar ist, weist eine vordere und hintere ilebelanordnung 2 auf. Diese besteht im wesentlichen aus Lascheii 3, die von mit den Sitzführungsschienen 1 in Verbindung stehenden Lagerstellen 4 aufgenommen werden und die sich nn der Sitzkissenvorderseite zusätzlich über StrcXaen 5 5 an Konsolen G abstutzen, die fest mit dem Fahrzeug verbunden sind.Liia motor vehicle seat, not shown, which is supported by seat guide rails 1 is displaceable in the longitudinal direction of the vehicle, has a front and rear fog arrangement 2 on. This consists essentially of Lascheii 3, which from with the seat guide rails 1 related bearings 4 are included and the nn of In addition, support the front of the seat cushion via StrcXaen 5 5 on brackets G, which fixed connected to the vehicle.

Die Laschen 3 auf einer Seite sind über die Lagerstellen hinaus verlängert und tragen ein Zahnsegment 7, das mit einem angedeuteten Ritzel 8 kämmt. Dieses bildet das Eiidglied eines selbsthemmenden, nicht wiedergegebenen Servoantriebes. In weiterhin nicht näher dargestellter Weise umgreifen die Lnschen 3 die konsolen- bzw. strebenseitigen Lagersteiltii 9 bzw. 10 gabelförmig, und die einander zugekehrten inncre?l Gabelabschnitte sind zur Übertragung der Stellbewegungen durch jeweils eine Welle 11 miteinander verbunde.The tabs 3 on one side are extended beyond the bearings and carry a toothed segment 7 which meshes with an indicated pinion 8. This forms the main element of a self-locking, not shown servo drive. In a manner not shown in any more detail, the lugs 3 encompass the console or strut-side bearing parts 9 or 10 fork-shaped, and those facing each other inncre? l fork sections are used to transmit the adjusting movements through each a shaft 11 connected to each other.

Durch gleichzeitiges Antreiben beider Ritzel 8 erfolgt wegen des gleichen Tei lkreisdurchmessers beider Zahnsegmente 7 eine weitestgehen parallel verlaufenden Änderung der Sitzhähe, während beim Antrieb nur eines der llitzel 8 uiiter Ausgleich des Längsverschiebeweges durch die Streben 5 eine Neigungsänderung des Sitzes eintritt. In beiden Fällen wird durch geeignete Endaiischläge oder Endschalter ein Austritt des Ritzels n aus dein jeweils zugeordneten Zahnsegment 7 verhindert.By simultaneously driving both pinions 8 takes place because of the same Partial circle diameter of both tooth segments 7 a largely parallel Change of seat height, while only one of the pinions 8 uiiter compensation when driving of the longitudinal displacement path through the struts 5, a change in the inclination of the seat occurs. In both cases, an exit is triggered by suitable end stops or limit switches of the pinion n from your respective associated tooth segment 7 prevented.
