Abstract
Description
Die Erfindung betrifft einen Airbag eines Kraftwagens gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to an airbag of a motor vehicle according to the preamble of patent claim 1.
Ein solcher Airbag ist der
In ihrer Rückhalteposition umgibt die Stützstruktur ein Rückhaltevolumen des Airbags zumindest bereichsweise. Die Stützstruktur kann dabei besonders schnell, d. h. in kurzer Zeit, aus der Aufbewahrungsposition in die Rückhalteposition bewegt werden und in der Rückhalteposition ein besonders großes Volumen im Innenraum des Kraftwagens einnehmen, so dass wenigstens ein Fahrzeuginsasse bei einer unfallbedingten Kraftbeaufschlagung und einer daraus resultierenden, unfallbedingten Verlagerung des Fahrzeuginsassen sehr gut aufgefangen, rückgehalten und vor schwerwiegenden Verletzungen geschützt werden kann.In its retention position, the support structure surrounds a retention volume of the airbag at least in regions. The support structure can be particularly fast, d. H. be moved from the storage position to the retention position in a short time, and occupy a particularly large volume in the interior of the motor vehicle in the retention position, so that at least one vehicle occupant very well caught in an accidental force application and a resulting accidental displacement of the vehicle occupant, and retained can be protected against serious injury.
Es ist dabei von Vorteil, wenn sich die Stützstruktur besonders schnell aus ihrer Aufbewahrungsposition in ihre Rückhalteposition bewegt.It is advantageous if the support structure moves very quickly from its storage position to its retention position.
Es ist daher Aufgabe der vorliegenden Erfindung, einen Airbag der eingangs genannten Art derart weiterzuentwickeln, dass die Stützstruktur besonders schnell aus ihrer Aufbewahrungsposition in ihre Rückhalteposition bewegt werden kann.It is therefore an object of the present invention, an airbag of the type mentioned in such a way that the support structure can be moved very quickly from its storage position to its retention position.
Um einen Airbag der im Oberbegriff des Patentanspruchs 1 angegebenen Art zu schaffen, dessen Stützstruktur besonders schnell, d. h. in besonders kurzer Zeit aus der Aufbewahrungsposition in die Rückhalteposition bewegbar ist, ist es erfindungsgemäß vorgesehen, dass die Stützstruktur einen Basisbereich aufweist, welcher einen Teil der Volumenelemente umfasst und in der Rückhalteposition in Stützanlage mit der Windschutzscheibe des Kraftwagens bewegbar ist. Von dem Basisbereich erstreckt sich in der Rückhalteposition beidseitig ein jeweiliger, jeweils einen weiteren Teil der Volumenelemente umfassender Seitenbereich der Stützstruktur zumindest im Wesentlichen in Fahrzeuglängsrichtung nach hinten weg. Vorzugsweise ist es vorgesehen, dass sich der Basisbereich in der Rückhalteposition der Stützstruktur in zumindest bereichsweiser Stützanlage mit der Windschutzscheibe befindet.To provide an airbag specified in the preamble of claim 1 species whose support structure particularly fast, d. H. is movable from the storage position into the retaining position in a particularly short time, it is provided according to the invention that the support structure has a base portion which comprises a part of the volume elements and is movable in the retaining position in support system with the windshield of the motor vehicle. From the base region extends in the retaining position on both sides of a respective, each a further part of the volume elements comprehensive side region of the support structure at least substantially in the vehicle longitudinal direction to the rear away. It is preferably provided that the base area is in the retaining position of the support structure in at least partially support system with the windshield.
Infolge dieser Ausgestaltung der Stützstruktur kann der Basisbereich nicht direkt bzw. unmittelbar mit einem Fahrzeuginsassen interagieren, wenn dieser bei einer unfallbedingten Kraftbeaufschlagung des Kraftwagens verlagert wird und auf die Stützstruktur aufprallt, was als Eintauchen bezeichnet wird. Diese mangelnde Integration führt zu einer besonders geringen Belastung des Fahrzeuginsassen, insbesondere wenn sich dieser in einer ungünstigen Position relativ zur Stützstruktur befindet. Eine solche ungünstige Position wird auch als Out-of-Position (OOP) bezeichnet. Mit anderen Worten kann der Fahrzeuginsasse, obwohl sich dieser in einer ungünstigen Position relativ zur Stützstruktur befindet, dennoch besonders vorteilhaft aufgefangen, rückgehalten und vor schwerwiegenden Verletzungen geschützt werden.As a result of this configuration of the support structure, the base portion can not directly or directly interact with a vehicle occupant when it is displaced in an accidental application of force of the motor vehicle and bouncing on the support structure, which is referred to as immersion. This lack of integration leads to a particularly low load on the vehicle occupant, especially if this is in an unfavorable position relative to the support structure. Such an unfavorable position is also referred to as out-of-position (OOP). In other words, although the vehicle occupant is in an unfavorable position relative to the support structure, the vehicle occupant can still be caught, retained and protected against serious injuries.
Die Anordnung des Basisbereichs unterstützt darüber hinaus die Bewegung der Stützstruktur, d. h. eine Entfaltung der Stützstruktur aus ihrer Aufbewahrungsposition in die Rückhalteposition, so dass eine besonders schnelle Befüllung des Rückhaltevolumens mit einem gasförmigen Medium, insbesondere mit Luft aus dem Innenraum des Kraftwagens, realisiert werden kann. Darüber hinaus kann eine besonders robuste Aufstellung der Stützstruktur in ihre Rückhalteposition erreicht werden, so dass sie eine vorteilhafte Stellung im Innenraum einnehmen und den Fahrzeuginsassen sehr gut auffangen kann.The arrangement of the base region further supports the movement of the support structure, i. H. a deployment of the support structure from its storage position to the retention position, so that a particularly rapid filling of the retention volume with a gaseous medium, in particular with air from the interior of the motor vehicle, can be realized. In addition, a particularly robust installation of the support structure can be achieved in its retention position, so that they occupy an advantageous position in the interior and can catch the vehicle occupant very well.
Der Basisbereich bietet aufgrund seiner entsprechenden Anordnung zwischen der Windschutzscheibe und den Seitenbereichen auch eine zusätzliche Schutzfunktion. Da der Basisbereich vor der Windschutzscheibe, d. h. zwischen der Windschutzscheibe und dem Fahrzeuginsassen und insbesondere zwischen der Windschutzscheibe und den Seitenbereichen angeordnet ist, kann die Gefahr, dass der Fahrzeuginsasse und insbesondere sein Kopf auf die Windschutzscheibe durchschlägt, besonders gering gehalten werden. Ebenso ist es möglich, ein solches Durchschlagen mittels des Basisbereichs abzumildern, was insbesondere dann vorteilhaft ist, wenn der Fahrzeuginsasse seinen Sicherheitsgurt nicht angelegt hat und somit nicht zusätzlich durch den Sicherheitsgurt rückgehalten wird.The base area also offers an additional protective function due to its corresponding arrangement between the windscreen and the side areas. Since the base area in front of the windshield, d. H. is arranged between the windshield and the vehicle occupant and in particular between the windshield and the side areas, the risk that the vehicle occupant and in particular his head strikes the windshield, can be kept particularly low. It is also possible to mitigate such penetration by means of the base region, which is particularly advantageous if the vehicle occupant has not put on his seat belt and thus is not additionally retained by the seat belt.
Darüber hinaus ist der erfindungsgemäße Airbag schnell und einfach an unterschiedliche Fahrzeuge, insbesondere Instrumententafeln, anbringbar. Dabei kann der Airbag, insbesondere hinsichtlich seiner Breite und/oder hinsichtlich der Ausgestaltung und Anordnung der Volumenelemente, besonders zeit- und kostengünstig an unterschiedliche Bedingungen im Innenraum des entsprechenden Fahrzeugs angepasst werden. Des Weiteren ist der erfindungsgemäße Airbag besonders einfach und kostengünstig herstellbar, da die Stützstruktur beispielsweise einfach zugeschnitten werden kann.In addition, the airbag according to the invention is quickly and easily attachable to different vehicles, in particular instrument panels. In this case, the airbag, in particular in terms of its width and / or in terms of the design and arrangement of the volume elements, particularly time and cost to be adapted to different conditions in the interior of the corresponding vehicle. Furthermore, the airbag according to the invention is particularly simple and inexpensive to produce, since the support structure can be easily cut, for example.
