Abstract

The seat and/or back rest of the vehicle seat is divided into individual segments (3) which owing to their inherent elasticity provide a resilient effect without the need for any extra means. These segments which can be made of a resilient pliable material such as sprung steel, fibre-glass reinforced plastics etc., may have traverse gaps between and can be covered with a suitable upholstery. The segments which can be dish-shaped to provide a good lateral support of the occupant are preferably attached to a common foundation member. These segments adapt more easily to the occupant for greater comfort without a heavy expensive structure.

Description

"Sitz, insbesondere für Kraftwagen' "Seat, especially for motor vehicles"

Die Erfindung betrifft einen Sitz, insbesondere für Kraftwagen.The invention relates to a seat, in particular for motor vehicles.

Herkörmliche Sitze fül- Kraftwagen bestehen im allgemeinen aus einem Rahmen mit darin befestigten Federn und einer darüber angeordneten Polsterauflage oder aber aus einer starren, praktisch unnachgiebigen Schale mit einer besonders dicken Polsterauflage. Der dazu erforderliche Aufwand an Bauelementen bedingt im allgemeinen ein relativ hohes Gewicht derartiger Sitze. Darüber hinaus weisen herkömmliche Kraftwagensitze durchweg den Nachteil auf, daß eine Verstellbarkeit verschiedener Körperauflagepunkte im Sitz- und Lehnenbereich zur Anpassung an die unterschiedlichen anatomischen Verhältnisse verschiedener Sitzbenutzer nur unter großem Aufwand möglich ist.Conventional seats for motor vehicles generally consist of one Frame with springs fastened in it and a cushion overlay or from a rigid, practically unyielding shell with a special one thick padding. The required expenditure on components depends on the generally a relatively high weight of such seats. In addition, conventional Motor vehicle seats consistently have the disadvantage that an adjustability of different Body support points in the seat and backrest area for adaptation to the different anatomical conditions of different seat users only possible with great effort is.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, diese Nachteile zu vermeiden und einen Sitz für Kraftwagen zu schaffen, der denkbar einfach nufgebaut ist, nur ein geringes Gewicht aufweist und eine weitgehende Anpassung an die anatomischen Verhältnisse des jeweiligen Benutzers zulässt.The present invention was therefore based on the object of addressing these disadvantages to avoid and to create a seat for a motor vehicle that is very easy to build is, only has a low weight and is largely adapted to the anatomical Conditions of the respective user allows.

Dies wird erfindungsgemäß dadurch erreicht, daß seine Sitz-und/oder Lehnenfläche in einzelne Segmente aufgeteilt ist bzw. sind, die aufgrund ihrer Elastizität ohne Zuhilfenahme weiterer Mittel eine federnde Wirkung ausüben.This is achieved according to the invention in that its seat and / or Backrest surface is divided into individual segments or are due to their elasticity exert a resilient effect without the aid of other means.

Durch dieses Bauprinzip sind - im Gegensatz zu bekannten Sitzen - Rahmen und Federelemente zu einer funktionellen Einheit zusammengefaßt, was einen besonders einfachen und kostengünstigen Aufbau ergibt.Due to this construction principle - in contrast to known seats - Frame and spring elements combined into a functional unit, what a particularly simple and inexpensive structure results.

Bei dem erfindungsgemäßen Sitz sind vorzugsweise zwischen den einzelnen Segmenten quer verlauf ende Spalte vorgesehen.In the seat according to the invention are preferably between the individual Segments transverse column provided.

Die einzelnen Segmente können vorteilhaft aus elastisch nachgiebigem Material wie Federstahl, glasfaserverstärktem Kunststoff oder dgl. bestehen.The individual segments can advantageously be made of elastically resilient Material such as spring steel, glass fiber reinforced plastic or the like. Exist.

Nach einer bevorzugten Ausführungsform der Erfindung sind den einzelnen Segmenten Spannelemente zugeordnet, die eine Variation der Federeigenschaften des jeweiligen Segments ermöglichen.According to a preferred embodiment of the invention are the individual Tensioning elements assigned to segments, which allow a variation of the spring properties of the enable the respective segment.

Zur Erhöhung des Sitzkomforts können die einzelnen Segmente mit einer Polsterung versehen sein.To increase the seating comfort, the individual segments with a Be provided with upholstery.

Eis onders giinstiger Aufbau ergibt stich, wenn die Segmente von Sitz- und Lehnenteil jeweils mit einem gemeinsamen Grundkörper verbunden sind.Ice or a favorable structure results when the segments of seating and backrest part are each connected to a common base body.

Gute Federeigenschaften des Sitzes und ein guter seitlicher Halt für den Sitzbenutzer werden erreicht, wenn die Segmente schalenförmig ausgebildet sind.Good spring properties of the seat and good lateral support for the seat user can be reached when the segments are shell-shaped.

Schließlich ist es noch vorteilhaft, wenn die Segmente über abgewinkelte Stützteile mit dem Grundkörper verbunden sind.Finally, it is also advantageous if the segments are angled over Support parts are connected to the base body.

Der Gegenstand der Erfindung soll im folgenden anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels näher erläutert werden.The object of the invention is to be based on one in the Drawing schematically illustrated embodiment will be explained in more detail.

In der Zeichnung zeigen Fig. 1 eine perspektivische Arisicht eines Kraftwagensitzes, und Fig. 2 eine Darstellung entsprechend Fig. 1, jedoch in einem Längssclinitt.In the drawing, FIG. 1 shows a perspective view of a Motor vehicle seat, and FIG. 2 shows a representation corresponding to FIG. 1, but in one Longitudinal sclinity.

Sitzteil 1 und Lehnenteil 2 des in der Zeichnung dargestellten Sitzes bestehen jeweils aus einzelnen Segmenten 3, die mit einem gemeinsamen Grundkörper 4 bzw. 5 verbunden sind. Die Segmente 3 sind schalenförmig ausgebildet und über abgewinkelte Stützteile 6 mit dem Grundkörper 4 bzw. 5 verbunden. Durch diese Ausbildung aus Schale und Stützteil werden besonders gute Federungseigenschaften erreicht. Aus Fig. 2 der Zeichnung ist zu ersehen, daß die einzelnen Segmente 3 z.B. durch Umschäumen mit einer Polsterung 7 versehen sind.Seat part 1 and backrest part 2 of the seat shown in the drawing each consist of individual segments 3, which have a common base body 4 and 5 are connected. The segments 3 are shell-shaped and over angled support parts 6 are connected to the base body 4 and 5, respectively. Through this training particularly good suspension properties are achieved from the shell and the support part. From Fig. 2 of the drawing it can be seen that the individual segments 3 e.g. Foam is provided with a padding 7.
