Abstract

The seat has a back rest and a seat surface with a spring unit (1), where the spring unit is formed as an arrangement for a person, which is arranged in the seat. The spring unit has bendings (4), which provide a tensile strength, and is adapted into its form of required spring effects. The spring unit is fastened at a seat frame in a longitudinal axial direction of the seat, and is composed of a fiber-reinforced plastic.

Description

Die Erfindung betrifft einen Sitz, bestehend aus einer Rückenlehne und einer Sitzfläche mit einem Federelement, insbesondere für Autositze.The The invention relates to a seat consisting of a backrest and a seat with a spring element, in particular for car seats.

Bekannte Fahrzeugsitzfedern bestehen vorzugsweise aus einem Drahtgeflecht als ein Federelement und aus einem darüberliegenden Schaumstoffpolster als Dämpfereinheit, deren Lage sich in der Sitzfläche befindet.Known Vehicle seat springs are preferably made of a wire mesh as a spring element and an overlying foam pad as damper unit, their location is in the seat located.

Aufgabe der Erfindung ist es, einen Sitz, bestehend aus einer Rückenlehne und einer Sitzfläche mit einem Federelement zu entwickeln, wobei der technische Aufwand verringert wird und deren Verwendung auch einen Rallyeeinsatz ermöglicht.task The invention is a seat consisting of a backrest and a seat with to develop a spring element, the technical complexity is reduced and their use also allows rallying.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass das Federelement als eine in einem Sitz angeordneten Anlage für eine Person ausgebildet ist, wobei das Federelement Krümmungen aufweist, die einer Zugbeanspruchung dienen, und das Federelement in seiner Form der jeweiligen geforderten Federwirkung angepasst ist, sowie das Federelement in Längsachsrichtung des Sitzes am Sitzgestell befestigt ist. Weitere Ausführungsformen der Erfindung sind in den Unteransprüchen dargestellt.According to the invention Task solved by that the spring element as a arranged in a seat plant for one Person is formed, wherein the spring element curvatures which serve a tensile stress, and the spring element adapted in its form of the respective required spring action is, as well as the spring element in the longitudinal axis direction the seat is attached to the seat frame. Further embodiments The invention are set forth in the subclaims.

Von besonderem Vorteil ist es, dass die körperschädlichen Vertikalbeschleunigungen, hervorgerufen durch Straßenunebenheiten, wesentlich vermindert werden. Dadurch erhöht sich auch die Fahrsicherheit.From It is particularly advantageous that the body-damaging vertical accelerations, caused by uneven roads, be substantially reduced. This also increases driving safety.

Nachfolgend wird die Erfindung anhand eines Ausführungsbeispieles näher erläutert. Die dazugehörige Zeichnung zeigt:following the invention will be explained in more detail with reference to an embodiment. The associated Drawing shows:

1: ein Federelement, 1 a spring element,

2: eine schematisch dargestellte Seitenansicht eines Sitzes und 2 : A schematically illustrated side view of a seat and

3: eine schematisch dargestellte Vorderansicht des Sitzes. 3 : A schematically illustrated front view of the seat.

1 zeigt ein Federelement 1, das für einen Sitz 5, bestehend aus einer Rückenlehne 2 und einer Sitzfläche 3, bestimmt ist. Das Federelement 1 ist als eine im Sitz 5 angeordnete Anlage für eine Person ausgebildet, wobei das Federelement 1 Krümmungen 4 aufweist, die der Zugbeanspruchung dienen. Das Federelement 1 ist in seiner Form der jeweiligen geforderten Federwirkung angepasst und in Längsrichtung des Sitzes 5 am nicht dargestellten Sitzgestell befestigt. Wie die 2 zeigt, ist das Federelement 1 im Bereich 6 der Rückenlehne 2 und im Bereich 7 der Sitzfläche 3 befestigt sowie im Bereich 8 des Überganges von der Rückenlehne 2 in die Sitzfläche 3 drehbar bzw. biegsam angeordnet. Im Bereich 9 der Sitzfläche 3 ist das Federelement 1 der Anatomie des menschlichen Körpers angepasst, wie 2 verdeutlicht. 3 zeigt die Vorderansicht des Sitzes 5 mit dem Federelement 1, wobei die Anordnung des Federelementes 1 im Sitz 5 dargestellt. Das Federelement 1 kann aus faserverstärktem Kunststoff, auf Kunststoff oder aus Metall bestehen. Das Federelement 1 kann auch in einer Sandwichbauweise ausgeführt sein. Weiterhin kann das Federelement 1 mit Sensoren und aktorischen Elementen, die elektronisch steuerbar sind, verbunden sein, um die Eigenschaften des Federelementes aktiv zu beeinflussen. 1 shows a spring element 1 that for a seat 5 , consisting of a backrest 2 and a seat 3 , is determined. The spring element 1 is as one in the seat 5 arranged system designed for a person, wherein the spring element 1 curvatures 4 has, which serve the tensile stress. The spring element 1 is adapted in its shape of the respective required spring action and in the longitudinal direction of the seat 5 attached to the seat frame, not shown. As the 2 shows is the spring element 1 in the area 6 the backrest 2 and in the area 7 the seat 3 attached as well as in the area 8th the transition from the backrest 2 in the seat 3 arranged rotatable or flexible. In the area 9 the seat 3 is the spring element 1 adapted to the anatomy of the human body, like 2 clarified. 3 shows the front view of the seat 5 with the spring element 1 , wherein the arrangement of the spring element 1 in the seat 5 shown. The spring element 1 can be made of fiber-reinforced plastic, on plastic or metal. The spring element 1 can also be designed in a sandwich construction. Furthermore, the spring element 1 be connected with sensors and actuator elements that are electronically controllable, to actively influence the properties of the spring element.
