Description
Die Erfindung betrifft einen Fahrzeugsitz gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to a vehicle seat according to the preamble of the claim 1.
Ein
gattungsgemäßer Fahrzeugsitz
ist aus den Dokumenten
Das Hauptproblem bei einem Seitencrash des Fahrzeugs ist die relativ weiche Seitensteifigkeit des Fahrzeugs bzw. der Seitenstruktur. Ein seitlich auf das Fahrzeug crashendes, d.h. auf die Seitenstruktur aufprallendes anderes Fahrzeug, dringt in das gecrashte Fahrzeug ein. Durch die feste Verbindung von Sitzstruktur und Bodenblech wird dabei sowohl die Fahrzeug- als auch die Sitzstruktur deformiert. Die Deformation des Fahrzeugsitzes führt jedoch dazu, dass der Überlebensraum für den Sitzbenutzer eingeschränkt wird, zumindest jedoch Hüftverletzungen die Folge sein können. Die Deformation der Seitenstruktur erfolgt in Abhängigkeit von der Wucht des Aufpralls teilweise so tief, dass der Überlebensraum für den Benutzer des Fahrzeugsitzes in kritischer Weise eingeschränkt wird, da sich die Seitenstruktur auf die Außenseite des Fahrzeugsitzes zubewegt und dabei den freien Raum verkleinert oder auch auf den Fahrzeugsitz auftreffen kann.The The main problem with a side crash of the vehicle is the relative soft lateral stiffness of the vehicle or the side structure. A side crash on the vehicle, i. on the page structure bouncing other vehicle, penetrates into the crashed vehicle one. Due to the fixed connection of seat structure and floor panel In this case, both the vehicle and the seat structure is deformed. However, the deformation of the vehicle seat causes the survival space for the Seat user restricted is, at least but hip injuries the result can be. The deformation of the page structure is dependent from the impact of the impact partly so deep that the survival space for the User of the vehicle seat is critically restricted, because the side structure moves toward the outside of the vehicle seat while reducing the free space or on the vehicle seat can hit.
Damit geht auch ein Problem für die Entfaltung eines evtl. vorhandenen Seitenairbags einher. Heutzutage werden Kraftfahrzeuge immer häufiger serienmäßig zusätzlich zu den seit längerem gebräuchlichen Frontalairbags mit Seitenairbags ausgestattet, zumindest für den Fahrer und den Beifahrer. Bei einem seitlichen Aufprall eines solchen Fahrzeugs werden die Seitenstrukturen, insbesondere die Vordertür, die B-Säule und die Hintertür in das Innere des Kraftfahrzeugs gedrückt. Ein dem Seitenairbag zugeordneter Sensor detektiert den Seitenaufprall und löst einen Gasgenerator aus, der schlagartig Gas in den Gassack des Seitenairbags strömen lässt, um diesen in Sekundenbruchteilen aufzublasen.In order to is also a problem for the unfolding of a possibly existing side airbags associated. nowadays Motor vehicles are becoming more common in addition to for a long time common Frontal airbags equipped with side airbags, at least for the driver and the passenger. In a side impact of such a vehicle become the side structures, in particular the front door, the B-pillar and the back door pressed into the interior of the motor vehicle. An associated with the side airbag Sensor detects the side impact and triggers a gas generator, which suddenly allows gas to flow into the airbag of the side airbag, around this one inflate in fractions of a second.
Der für die Entfaltung des Seitenairbags notwendige Entfaltungsfreiraum in der Zündphase des Airbags wird durch die intrudierte Fahrzeug-Seitenstruktur verkleinert, auch wenn ein Abstand zwischen der Seitenstruktur und der Außenseite des Fahrzeugsitzes verbleibt. Die Eindringgeschwindigkeit der Seitenstruktur bei einem Seitencrash kann so hoch sein, dass sich der Seitenairbag noch nicht voll entfaltet hat, wenn der Sitzbenutzer in den Gassack des Seitenairbags eintaucht. Dadurch entfaltet sich der Airbag nicht immer optimal. Die Folge hiervon ist, dass der Seitenairbag als passive Rückhaltekomponente seine Funktion nicht in vollem Umfang wahrnehmen kann.Of the for the Unfolding the side airbag necessary unfolding freedom in the ignition phase of the airbag is reduced by the intruded vehicle side structure, even if a distance between the page structure and the outside of the vehicle seat remains. The penetration rate of the page structure in a side crash can be so high that the side airbag has not fully unfolded when the seat occupant in the gas bag of the side airbag. As a result, the airbag does not unfold always optimal. The consequence of this is that the side airbag as passive retention component its Function can not fully perceive.
Diese Problematik wird dadurch vergrößert, dass bei dem Seitenaufprall auf die Seitenstruktur die gesamte Seitenwand bzw. Seitenstruktur gestaucht wird und sich dadurch verhärtet. Hierdurch bedingt verschlechtert sich die Dämpfung und der Aufschlag der Fahrzeuginsassen wird härter.These Problem is magnified by the fact that in the case of the side impact on the side structure, the entire side wall or side structure is compressed and thereby hardened. hereby conditionally worsens the damping and the impact of the Vehicle occupants get harder.
Ferner werden die gesetzlichen Vorschriften und Anforderungen für die zulässige Belastung von Fahrzeuginsassen bei einem Seitencrash ständig erhöht, so dass ein andauerndes Bedürfnis dafür besteht, das Seitencrashverhalten von Fahrzeugen zu verbessern. Hierzu ist bekannt, aktive Stützelemente aus dem Fahrer- und Beifahrersitz sowohl in Richtung zu dem Fahrzeuginneren als auch in Richtung zu den außen liegenden Seitenstrukturen des Fahrzeugs auszufahren und hierdurch im Falle eines Seitencrashs einen mechanischen, Last aufnehmenden Querverbund durch das Fahrzeug zu bilden. Nachteilig bei diesem bekannten System ist jedoch, dass aufgrund der Verstellbarkeit der Fahrzeugsitze in ihrer Längsposition sowie der Verstellbarkeit der Lehnenteile in ihrer Neigung in aller Regel die Lehnenteile aufgrund individuell vorgenommener Einstellungen im Fahrzeug nicht genau für einen solchen Querverbund nebeneinander angeordnet sind.Further Be the legal requirements and requirements for the allowable load of vehicle occupants in a side crash constantly increased, so that a lasting desire insists to improve the side crash behavior of vehicles. This is known, active support elements the driver and passenger seats both toward the vehicle interior as well as towards the outside extending side structures of the vehicle and thereby in the case of a side crash, a mechanical load-bearing cross-connection to form through the vehicle. A disadvantage of this known system However, that is due to the adjustability of the vehicle seats in their longitudinal position and the adjustability of the backrest parts in their inclination in all Rule the backrest parts due to individually made settings in the Vehicle not exactly for such a cross-connection are arranged side by side.
Der Erfindung liegt die Aufgabe zugrunde, Fahrzeugsitze derart zu verbessern, dass das Seitencrashverhalten mit einem geringen konstruktiven Aufwand verbessert wird.Of the Invention is based on the object to improve vehicle seats such that the side crash behavior with a low design cost is improved.
Die Aufgabe wird erfindungsgemäß durch einen Fahrzeugsitz mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen und der nachfolgenden Beschreibung mit zugehörigen Zeichnungen.The Task is achieved by a vehicle seat with the features of claim 1 solved. preferred Refinements and developments of the invention will become apparent the dependent claims and the following description with accompanying drawings.
Ein erfindungsgemäßer Fahrzeugsitz, insbesondere für ein Kraftfahrzeug, umfasst ein Sitzteil, ein Lehnenteil und eine Sitzhalterung, die derart ausgebildet ist, dass der Fahrzeugsitz bei einem Seitenaufprall, insbesondere bei einem Seitenaufprall auf die bei einem unfallbedingten Eindringen der neben dem Fahrzeugsitz verlaufenden Seitenstruktur des Fahrzeugs in das Innere des Fahrzeugs, eine in Wirkungsrichtung des Seitenaufpralls zum Fahrzeuginnern hin gerichtete Querbewegung des Fahrzeugsitzes zulässt, und weist die Besonderheit auf, dass die Sitzhalterung mindestens ein den Fahrzeugsitz in Querrichtung fixierendes Halteelement umfasst, das eine Sollbruchstelle aufweist, die beim Überschreiten einer vorgegebenen Querbelastung des Fahrzeugsitzes bricht und dabei dessen Bewegung in seiner Querrichtung freigibt.An inventive vehicle seat, in particular for a motor vehicle, comprises a seat part, a backrest part and a seat support, which is designed such that the vehicle seat in a side impact, in particular in a side impact on the case of an accidental intrusion of running next to the vehicle seat side structure of the vehicle in the interior of the vehicle, in the direction of action of the side impact to the vehicle interior directed transverse movement of the vehicle seat permits, and has the peculiarity that the seat support comprises at least one vehicle seat transversely fixing retaining element having a predetermined breaking point, which exceeds a predetermined transverse load of Fahrzeugsit zes breaks and thereby releases its movement in its transverse direction.
Ein erfindungsgemäßer Fahrzeugsitz ist nicht fester Bestandteil der Crash-Struktur, in der er Abstützungsaufgaben erfüllt und dabei durch die Krafteinwirkung verformt wird, sondern der Fahrzeugsitz wird aus der Crash-Struktur entkoppelt. Dadurch wird der "Überlebensraum Fahrzeugsitz" in seiner Größe nicht bzw. weniger durch Deformationen u.ä. verkleinert und bietet dem Sitzbenutzer solange wie möglich einen Schutz vor Verletzungen, insbesondere durch Zusammendrücken in Querrichtung.One Inventive vehicle seat is not an integral part of the crash structure in which it performs support tasks Fulfills and is deformed by the force, but the vehicle seat is decoupled from the crash structure. As a result, the "survival vehicle seat" in its size does not or less by deformations and the like. reduced and offers the Sit users as long as possible protection against injury, in particular by compression in Transverse direction.
In weiterer vorteilhafter Ausgestaltung kann vorgesehen sein, dass der Fahrzeugsitz ein die Querbewegung des Fahrzeugsitzes dämpfendes Element aufweist. Ein solches dämpfendes Element kann im Crashfall Spitzenbelastungen und Kraftspitzen von dem Sitzbenutzer abhalten oder abmildern.In Another advantageous embodiment may be provided that the vehicle seat a the transverse movement of the vehicle seat damping element having. Such a dampening Element can in the event of a crash peak loads and force peaks of discourage or mitigate the seat user.
Besonders vorteilhaft wird der Fahrzeugsitz mit einem in den Fahrzeugsitz integrierten Gurt und/oder einem Gurtstraffer kombiniert, wodurch der Sitzbenutzer fester an den Fahrzeugsitz gebunden wird.Especially Advantageously, the vehicle seat with a in the vehicle seat integrated belt and / or a belt tensioner combined, thereby the seat occupant is tied tighter to the vehicle seat.
In einer weiteren vorteilhaften Ausgestaltung kann vorgesehen sein, dass der Fahrzeugsitz auf seiner Außenseite, der Seitenstruktur des Fahrzeugs zugewandten Seite, ein Hüftschutzelement aufweist, dass sich im Falle eines Seitenaufpralls auf die Seitenstruktur des Fahrzeugs nach oben bewegt, um die zur Außenseite gewandte Hüfte des Sitzbenutzers gegen die in das Fahrzeug eindringende Seitenstruktur vor Verletzungen zu schützen. Das Hüftschutzelement kann beispielsweise ein festes Element sein, das aufgestellt, ausgeschwenkt oder ausgefahren wird, beispielsweise eine Sitzseitenwange, oder ein im Bereich des Sitzteils des Fahrzeugsitzes angeordneter Seitenairbag.In a further advantageous embodiment can be provided that the vehicle seat on its outside, the side structure the vehicle-facing side, a hip protection element has that in the event of a side impact on the side structure of the vehicle moved up to the outside skilled hip of the seat occupant against the penetrating into the vehicle side structure to protect against injury. The hip protection element For example, it may be a solid element that is erected, swung out or extended, for example, a seat side cheek, or a arranged in the region of the seat part of the vehicle seat side airbag.
