Abstract
Description
Die Erfindung betrifft eine Seitenaufprall-Schutzvorrichtung für Fahrzeuge, mit einem aufblasbaren Gassack, der sich zwischen einer Seitenstruktur des Fahrzeugs und dein Thoraxbereich eines Fahrzeuginsassen entfaltet.The invention relates to a side impact protection device for vehicles, with an inflatable gas bag, which is between a side structure of the vehicle and your thorax area of a vehicle occupant.
Die derzeit zum Schutz des Thoraxbereichs eines Fahrzeuginassen eingesetzten Seitenaufprall-Schutzvorrichtungen umfassen meistens einen kissenförmigen Gassack, der sich aufgrund seines flächigen Aufbaus im wesentlichen in einer zur Fahrzeugseitenstruktur parallelen Ebene entfaltet und durch das Aufblasen mittels einen Gaszufuhreinrichtung eine Ausdehnung in der dazu senkrechten Querrichtung des Fahrzeugs erfährt. Der Abstand des Fahrzeuginsassen von der Fagrzeugseitenstruktur, insbesondere der Fahrzeugtür, variiert abhängig vom Körperaufbau des Insassen erheblich. Dieser Umstand wurde bei der Auslegung der Seitenaufprall-Schutzvorrichtungen, insbesondere beim Gassack-Design, bisher nicht berücksichtigt. Der Gassack einer herkömmlichen Seitenaufprall-Schutzvorrichtung entfaltet sich unabhängig von der Körpergröße des Fahrzeuginsassen, so daß Insassen mit einem relativ schmalen Brustkorb bei einer Fahrzeugintrusion im Vergleich zu Insassen mit einem relativ breiten Brustkorb erst zu einem späteren Zeitpunkt durch den aufgeblasenen Gassack in Richtung Fahrzeuginnenraum beschleunigt werden.The currently used to protect the chest area Side impact protection devices used in vehicle occupants usually include a pillow-shaped Airbag, which due to its flat structure essentially unfolded in a plane parallel to the vehicle side structure and through the inflation by means of a gas supply device an expansion experienced in the perpendicular transverse direction of the vehicle. The Distance of the vehicle occupant from the vehicle side structure, in particular the vehicle door, varies depending on body composition of the occupant significantly. This fact was taken into account when interpreting the Side impact protection devices, especially in gas bag design, not yet taken into account. The gas bag of a conventional one Side impact protection device unfolds independently the height of the vehicle occupant, so that inmates with a relatively narrow chest in a vehicle intrusion compared to occupants with a relatively wide chest first to a later one Time through the inflated airbag towards the vehicle interior be accelerated.
Die Erfindung schafft eine Seitenaufprall-Schutzvorrichtung, die eine möglichst frühzeitige Beschleunigung des Fahrzeuginsassen in den Fahrzeuginnenraum ermöglicht.The invention provides a side impact protection device the one if possible early Allows acceleration of the vehicle occupant into the vehicle interior.
Gemäß der Erfindung ist bei einer Seitenaufprall-Schutzvorrichtung der eingangs genannten Art vorgesehen, daß wenigstens ein Mittel zur Begrenzung der Entfaltung des Gassacks in Fahzeuglängsrichtung vorgesehen ist. Durch die erfindungsgemäße Begrenzung der Gassackentfaltung in Fahrzeuglängsrichtung kann sich der Gassack früher und stärker in der Querrichtung des Fahrzeugs ausdehnen. Der Gassack ist somit sehr schnell optimal positioniert, so daß der Fahrzeuginsasse bereits zu einem sehr frühen Zeitpunkt an der Beschleunigung in Richtung Fahrzeuginnenraum teilnimmt. Ein weiterer Vorteil der Erfindung besteht darin, daß aufgrund der frühen Querausdehnung des Gassacks der Gassackinnendruck zu Beginn der Entfaltung relativ gering sein kann und erst nachfolgend ansteigt.According to the invention is one Side impact protection device of the type mentioned is provided, that at least a means for limiting the deployment of the gas bag in the longitudinal direction of the vehicle is provided. By limiting the airbag deployment according to the invention in the longitudinal direction of the vehicle the gas bag can change earlier and stronger expand in the transverse direction of the vehicle. The gas bag is thus very quickly optimally positioned so that the vehicle occupant already at a very early Time participates in the acceleration towards the vehicle interior. Another advantage of the invention is that due to the early Transverse expansion of the gas bag the gas bag pressure at the beginning of Unfolding can be relatively low and only increases subsequently.
Als Mittel zur Begrenzung der Entfaltung des Gassacks in Fahrzeuglängsrichtung ist vorzugsweise wenigstens ein innerhalb des Gassacks angeordnetes Fangband vorgesehen, das sich im entfalteten Zustand des Gassacks im wesentlichen in Fahrzeuglängsrichtung erstreckt.As a means to limit development of the gas bag in the vehicle's longitudinal direction is preferably at least one arranged inside the gas bag Tether provided that the gas bag is unfolded essentially in the longitudinal direction of the vehicle extends.
Gemäß der bevorzugten Ausführungsform der Erfindung ist der Gassack in der Rückenlehne eines Fahrzeugsitzes verstaut und entfaltet sich bei einem Seitenaufprall aus der Rückenlehne heraus.According to the preferred embodiment of the Invention is the gas bag in the backrest of a vehicle seat stowed and unfolded in the event of a side impact from the backrest out.
