Abstract
Description
Die Erfindung bezieht sich auf einen Fahrzeugsitz für Kraftfahrzeuge, wie er im Oberbegriff des Hauptanspruchs beschrieben ist.The The invention relates to a vehicle seat for motor vehicles, as in The preamble of the main claim is described.
Bei Kraftfahrzeugen werden in zunehmendem Maße Fahrzeugsitze eingebaut, bei denen an der Außenseite des Lehnenrahmens (also zwischen dem Lehnenrahmen und benachbarten Karosserieabschnitten wie Fahrzeugtür, B-Säule usw.) ein Seitenairbag integriert ist. Dessen Aufgabe ist es, bei einem Seitenaufprall den Insassen vor Verletzungen zu schützen.at Motor vehicles are increasingly being fitted with vehicle seats, where on the outside the back frame (ie between the back frame and adjacent Body sections such as vehicle door, B-pillar etc.) a side airbag is integrated. Its task is with a side impact to protect the occupants from injury.
Des Weiteren sind die Lehnen der Fahrzeugsitze üblicherweise mit einem meistens aus Metall bestehenden Lehnenrahmen versteift. Bei bestimmten Ausführungen von Fahrzeugsitzen, insbesondere bei so genannten Sportsitzen weisen die Lehnenrahmen an den Längsseiten Lehenholme auf, die nach vorne – in Fahrtrichtung gesehen – orientiert sind. Sie stützen die Körperseiten des Fahrzeuginsassen ab und geben ihm auf diese Weise zusätzlichen Halt.Of Further, the backrests of the vehicle seats are usually one with most stiffened metal back frame. For certain versions of vehicle seats, especially in so-called sports seats have the backrest frames on the long sides Lehenholme on, the forward - in Direction seen - oriented are. They support the body sides of the vehicle occupant and give him in this way additional Stop.
Es hat sich jedoch gezeigt, dass sich bei einem Seitencrash die Fahrzeugtür bzw. die sie umgebenden Karosserieabschnitte so schnell und stark verformen, dass sich in Folge auch der Lehnenrahmen des Sitzes in Richtung des Insassen verformt und ihn vor allem im Rippenbereich verletzen kann. Mit anderen Worten: Bei einem solchen Seitencrash verbleibt der Fahrzeuginsasse aufgrund seiner Trägheit am selben Ort im Raum, während sich die eindringenden Karosserieabschnitte relativ gesehen auf den Fahrzeuginsassen zubewegen. Der Fahrzeugsitz wird sozusagen unter dem Insassen weggezogen. Die erwähnten Lehnenholme erhöhen die Verletzungsgefahr noch erheblich. Der herkömmliche Seitenairbag kann dies nicht verhindern, da er sich lediglich zwischen dem Oberkörper des Fahrzeuginsassen und den eindringenden Karosserieabschnitten entfaltet.It However, it has been shown that in a side crash the vehicle door or the deforming surrounding body sections so quickly and strongly, that in consequence also the backrest frame of the seat in direction deformed the occupant and hurt him especially in the rib area can. In other words, with such a side crash remains the vehicle occupant due to its inertia in the same place in space, while the penetrating body sections relative to the Move vehicle occupants. The vehicle seat is, so to speak, under moved away from the inmate. The mentioned Increase backrests the risk of injury even more. The conventional side airbag can do this not prevent, since he only between the upper body of the Vehicle occupants and the invading body sections deployed.
Aufgabe der Erfindung ist es, einen gattungsgemäßen Fahrzeugsitz so auszugestalten, dass er den Fahrzeuginsassen bei einem Seitencrash noch besser schützt.task The invention is to provide a generic vehicle seat in such a way that it better protects the vehicle occupants in the event of a side crash.
Die Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The Object is according to the invention with the characterizing Characteristics of claim 1 solved. Further embodiments of the invention will become apparent from the dependent claims.
Nach der Erfindung ist demnach zwischen dem Fahrzeuginsassen und wenigstens dem Lehnenholm, der den eindringenden Karosserieabschnitten zugewandt ist, ein Airbag vorgesehen. Dieser Airbag kann neben dem herkömmlichen Seitenairbag als zusätzliche Schutzreinrichtung vorgesehen sein, er bedingt aber nicht den Seitenairbag. Im Crashfall wird der erfindungsgemäße Airbag in der üblichen Weise über einen Gasgenerator in Sekundenbruchteilen aufgeblasen, so dass er ein schützendes Luftpolster zwischen den betroffenen Köperabschnitten des Fahrzeuginsassen und dem Lehnenholm aufbauen kann. Dabei erfolgt die Gaserzeugung über einen getrennten Gasgenerator. Soweit auch ein Seitenairbag vorgesehen ist, kann es vorteilhaft sein, diesen Gasgenerator – durch entsprechende Dimensionierung – mitzuverwenden. Das Gleiche gilt für den Auslösemechanismus.To Accordingly, the invention is between the vehicle occupant and at least the backrest spar, which faces the penetrating body sections is, an airbag provided. This airbag can be in addition to the conventional Side airbag as additional Protective device may be provided, but it does not require the side airbag. In the event of a crash, the airbag according to the invention in the usual manner via a Inflated inflator in fractions of a second, allowing it to protective Air cushion between the affected body parts of the vehicle occupant and can build the backrest spar. The gas is generated via a separate gas generator. As far as a side airbag provided is, it may be advantageous to this gas generator - through appropriate dimensioning - to be used. The same goes for the Trigger mechanism.
Die Anbringung des erfindungsgemäßen Airbags ist auf beschriebene, der Karosserie zugewandten Sitzseite nicht beschränkt. Es kann ebenso gut ein zweiter Airbag in der innenliegenden, zur Fahrzeugmitte zeigenden Sitzseite verbaut sein. In diesem Fall ist der Insasse auch bei einem Seitencrash auf der Beifahrerseite geschützt.The Attachment of the airbag according to the invention is not on described, the body facing seat side limited. It may as well be a second airbag in the inside, for Vehicle center facing seat side to be installed. In this case is the occupant protected even in the event of a side crash on the passenger side.
Komfortable Sportsitze sehen eine Möglichkeit für die Verstellung der Lehnenbreite vor. Auf diese Weise kann sich der Fahrzeuginsasse die ihm Halt gebenden Lehnenabschnitte für seine Körpergröße optimal einstellen. Die Lehnenverstellung erfolgt in der Regel über einen Luftsack, der zwischen wenigstens einem Lehnenholm und einem dem Fahrzeuginsassen zugewandten als Polsterung dienenden Schaumteil. Wird der Luftsack aufgeblasen, drückt er zunehmend das Schaumteil gegen die Körperseite des Fahrzeuginsassen.comfortable Sports seats see a possibility for the Adjustment of the backrest width. In this way, the Vehicle occupant to give him support back sections for his Body size optimal to adjust. The backrest adjustment is usually done via a Airbag, between at least one backrest spar and a Vehicle occupants facing as foam padding foam part. When the airbag is inflated, it increasingly presses the foam part against the body side of the Vehicle occupants.
In einer vorteilhaften Ausgestaltung sieht die Erfindung in einem solchen Fall einen Airbag vor, der dem Luftsack für die Lehnenbreitenverstellung vorgelagert ist, das heißt, er befindet sich zwischen diesem Luftsack und dem Schaumteil.In an advantageous embodiment, the invention provides in such Case an airbag, the air bag for the backrest width adjustment is upstream, that is, it is located between this airbag and the foam part.
In einer weiteren zweckmäßigen Ausgestaltung sind der Luftsack für die Lehnenverbreiterung und der Airbag für den Kollisionsfall zu einem einzigen Bauteil zusammengefasst. In diesem Fall liegt es auf der Hand, dass der Luftsack in seiner Ausgestaltung den bekannten Anforderungen eines Airbags genügen muss. Des Weiteren wird die Luftzufuhr zum Aufblasen des Sacks je nach Einsatzfall entweder durch eine die Luftmenge regulierende Luftpumpe (Lehnenbreitenverstellung) oder durch einen herkömmlichen Gasgenerator (Airbagfunktion) erfolgen.In a further advantageous embodiment are the airbag for the Lehnenverbreiterung and the airbag for the collision case to a single component combined. In this case, it lies on the Hand, that the airbag in its configuration the known requirements an airbag suffice got to. Furthermore, the air supply to inflate the bag is ever after use, either by an air volume regulating Air pump (backrest width adjustment) or by a conventional Gas generator (airbag function) done.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus der nachfolgenden Beschreibung anhand der dazugehörenden Zeichnung. Es zeigenFurther advantageous embodiments of the invention will become apparent from the following description with reference to the accompanying drawings. Show it
