Abstract

The airbag system is activated by collision sensors. The protection is enhanced by ensuring that the occupant is correctly positioned in the seat before the full airbag (4) pressure is released. This is achieved by a progressive action airbag, or by additional position control airbags or by movable padded sections of the seat. The collision sensor action is extended to include a more sensitive, longer reach mode, to pre-empt the main sensor action. This can include microwave proximity sensors which can be used to predict a collision. The position control airbag action can be powered by a separate pressure source powered from a reservoir and pumped by the engine. ADVANTAGE - Occupant is correctly positioned for maximum protection from airbag, less injury risk.

Description

Die Erfindung betrifft eine Sicherheitsvorrichtung gemäß dem Oberbegriff des Patentanspruchs 1. Die Aktivierung des Airbags erfolgt bekanntlich in Abhängigkeit von Signalen eines den Beginn eines Unfalls signalisierenden Sensors, beispielsweise eines Beschleunigungs- bzw. Verzögerungssensors oder eines außen am Fahrzeug angebrachten Berührungssensors, der bei bekannten Konstruktionen mehrere normalerweise in einem definierten Abstand verlaufende Kontaktleisten enthält, die nach crash­ bedingter Verformung in Berührung miteinander gelangen.The invention relates to a safety device according to the Preamble of claim 1. The activation of the airbag is known to occur depending on the signals of one of the Start of an accident signaling sensor, for example an acceleration or deceleration sensor or one outside attached to the vehicle touch sensor, which in known Constructions usually defined in one Contains spaced contact strips that after crash contingent deformation come into contact with each other.

Ein Problem beider vollen Aktivierung des Airbags entsteht dadurch, daß er im Hinblick auf einen in einer vorgegebenen Rückhalteposition befindlichen Insassen ausgelegt ist, der Insasse aber im Augenblick des Crashs und der Aktivierung des Airbags gerade eine davon abweichende Position inne haben kann. Bei einem seitlich des Insassen angeordneten, dem Seitenschutz insbesondere des Kopf- und Brustbereichs des Insassen dienenden Airbag ergeben sich so Schwierigkeiten, wenn sich Kopf und Brustbereich des Fahrzeuginsassen nicht etwa in der Mitte des zugehörigen Fahrzeugsitzes befinden, sondern der Insasse seinen Kopf beispielsweise nahe dem Seitenairbag abgestützt hat. Wird dieser Airbag bei einem Crash dann sofort voll aktiviert, können infolge des sehr geringen Ausgangsabstands zwischen Airbag und Fahrzeuginsassen unerwünschte Belastungen des Insassen auf­ treten. A problem arises when the airbag is fully activated in that it is with respect to one in a given Restraint position is designed occupant who But occupants at the moment of the crash and the activation of the Airbags can have a different position. With a side protection arranged on the side of the occupant especially serving the head and chest area of the occupant Airbag difficulties arise when head and head Chest area of the vehicle occupant is not approximately in the middle of the associated vehicle seat, but the occupant his Head, for example, has supported near the side airbag. Becomes this airbag can then be fully activated immediately in the event of a crash due to the very small initial distance between the airbag and Vehicle occupants have undesirable loads on the occupant to step.  

Aus diesem Grunde sind beispielsweise aus der DE-PS 38 09 074, B60R 21/16, und der DE-OS 40 19 677, B60R 21/26, bereits Airbag­ systeme bekannt, die zunächst relativ "sanft" oder schwach auf­ geblasen werden, damit der Aufprall auf den out of position sitzenden Fahrzeuginsassen nicht zu stark ist, und die dann anschließend voll aktiviert werden. Hier besteht jedoch die Gefahr, daß ein Teil des Verzögerungswegs für den Fahrzeugin­ sassen verloren geht.For this reason, for example from DE-PS 38 09 074, B60R 21/16, and DE-OS 40 19 677, B60R 21/26, already airbag systems known to be relatively "gentle" or weak at first be blown so that the impact hits the out of position seated vehicle occupants is not too strong, and then then be fully activated. Here, however, there is Risk of part of the deceleration distance for the vehicle get lost.

Aus der DE-OS 40 23 109, B60R 21/32, ist auch bereits ein In­ sassenschutzsystem für Fahrzeuge bekannt, bei dem laufend die jeweilige Sitzposition des betreffenden Insassen in Relation zu den zugeordneten Insassenschutzvorrichtungen gemessen wird; daraus werden die Zeitpunkte und der Umfang der einzuleitenden Schutzmaßnahmen abgeleitet. Abgesehen von dem relativ großen Aufwand, der bei dieser Lösung letztlich für jeden Fahrzeugin­ sassen bzw. für jeden Sitzplatz im Fahrzeug zu treiben ist, nimmt auch dieser Stand der Technik die out of position - Situation des jeweiligen Insassen als gegeben an.From DE-OS 40 23 109, B60R 21/32, there is already an In known vehicle protection system, in which the respective seating position of the occupant in relation to the associated occupant protection devices is measured; from this, the times and the extent of those to be initiated Protective measures derived. Except for the relatively large one The effort involved in this solution ultimately for every vehicle sitting or driving for every seat in the vehicle, this state of the art also takes the out of position - Situation of the respective occupant as given.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Sicherheitsvorrichtung zu schaffen, die mit möglichst geringem zusätzlichen Aufwand für gleichbleibende Verhältnisse im Augen­ blick der vollen Aktivierung des Airbags sorgt.The invention has for its object a generic To create safety device with the lowest possible additional effort for constant conditions in the eye view of full activation of the airbag.

Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kenn­ zeichnenden Merkmalen des Hauptanspruchs, vorteilhafte Ausbil­ dungen der Erfindung beschreiben die Unteransprüche.The inventive solution to this problem consists in the drawing features of the main claim, advantageous training The invention describes the subclaims.

Während beim Stand der Technik also out of Position - Situatio­ nen als gegeben hingenommen werden und lediglich eine Verzöge­ rung der vollen Aktivierung des Airbags vorgenommen wird, sieht die Erfindung eine Positionierung des Insassen in seiner vorge­ gebenen Rückhalteposition vor. Im Augenblick der vollen Aktivie­ rung des Airbags liegen demgemäß stets gleiche Verhältnisse hin­ sichtlich der relativen Lage von Fahrzeuginsasse und Airbag vor. So while in the state of the art out of position - situation are accepted as given and only a delay tion of full activation of the airbag is made the invention a positioning of the occupant in its pre given retention position. At the moment of full activation Airbag are therefore always the same conditions the relative position of the vehicle occupant and airbag.  

Selbst wenn die dazu vorgesehenen Mittel ebenfalls einen Airbag oder ggf. denselben Airbag, wie er den eigentlichen Bestandteil der Sicherheitsvorrichtung bildet, verwenden, erfolgt, ausgelöst zweckmäßigerweise durch einen Precrash-Sensor, die Aktivierung dieses Airbags mit einem derart hoch gewählten Druck, daß er zwar nicht die eigentliche Sicherheitsaufgabe wahrnimmt, aber dafür sorgt, daß der Fahrzeuginsasse in seine vorgegebene Rück­ halteposition bewegt wird. Dies bedeutet verständlicherweise eine entsprechende Dimensionierung des Positionierungsairbags so, daß er den jeweiligen Fahrzeuginsassen (oder einen theo­ retischen mittleren Fahrzeuginsassen) in die Rückhalteposition zu bewegen vermag.Even if the means provided are also an airbag or possibly the same airbag as it is the actual component the safety device forms, use, takes place, triggered expediently by a pre-crash sensor, the activation this airbag with such a high pressure that it does not perform the actual security task, but ensures that the vehicle occupant in its predetermined return holding position is moved. This means understandably an appropriate dimensioning of the positioning airbag in such a way that it corresponds to the respective vehicle occupant (or a theo middle vehicle occupants) in the restraint position able to move.

Bereits an dieser Stelle sei eingefügt, daß die Mittel nicht notwendigerweise ebenfalls einen Airbag zu enthalten brauchen, sondern daß dazu auch bei Beginn eines Crashs verschiebbare oder drehbare Klappen oder Polster Verwendung finden können.At this point it should be added that the funds are not necessarily also need to contain an airbag, but that it can be moved at the beginning of a crash or rotatable flaps or upholstery can be used.

Wie in den Unteransprüchen zum Ausdruck gebracht, ist es zweck­ mäßig, zum Betrieb dieser Positionierungsmittel einen separaten Druckspeicher zu verwenden, der vorzugsweise ventilgesteuert mit einem fahrzeugeigenen Kompressor zwecks erneuten Aufladens ver­ bindbar ist. Weiterhin können die Mittel insbesondere dann, wenn der eigentliche Sicherheitsairbag nicht voll ausgelöst worden ist, durch Verbindung mit einer Unterdruckquelle des Fahrzeugs, wie sie beispielsweise der Antriebsmotor zur Verfügung stellt, wieder in ihre Ursprungslage zurückgeführt ("regeneriert") werden.As expressed in the subclaims, it is useful moderate, a separate to operate this positioning To use pressure accumulator, which is preferably valve-controlled with an in-vehicle compressor for recharging is binding. Furthermore, the funds can in particular if the actual safety airbag has not been fully deployed by connecting to a vacuum source of the vehicle, such as that provided by the drive motor, returned to its original position ("regenerated") become.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung erläutert, deren Fig. 1 einen Querschnitt durch den Dachsäulenbereich eines Fahrzeugs mit einem dem Seitenschutz des Kopfes des benachbart sitzenden Fahrzeuginsassen dienenden Airbag wiedergibt, während Fig. 2 zugeordnete elektrische und pneumatische Einzelheiten zeigt. An exemplary embodiment of the invention is explained below with reference to the drawing, in which FIG. 1 shows a cross section through the roof pillar region of a vehicle with an airbag serving to protect the side of the head of the adjacent seated vehicle occupant, while FIG. 2 shows associated electrical and pneumatic details.

Betrachtet man zunächst Fig. 1, so erkennt man bei 1 die Dach­ säule, die bei 2 in üblicher und daher nicht zu beschreibender Weise mit Türdichtungen ausgerüstet ist. In der Dachsäule 1 ist der Gasgenerator 3 für den in seinem aktivierten Zustand ge­ zeichneten Seitenairbag 4 angedeutet. Einzelheiten hinsichtlich Gasgenerator 3 und Airbag 4 brauchen nicht beschrieben zu wer­ den, da sie dem Fachmann bestens bekannt sind. Bekannt ist auch, daß der Gasgenerator 3 den Airbag 4 durch schnelle Zufuhr von Gas dann aufbläst (aktiviert), wenn ein Sensor ein einen Crash anzeigendes elektrisches Signal an eine Zündvorrichtung liefert.Looking first at Fig. 1, one can see at 1 the roof pillar, which at 2 is equipped in the usual and therefore not to be described manner with door seals. In the roof pillar 1 , the gas generator 3 is indicated for the side airbag 4 drawn in its activated state. Details regarding gas generator 3 and airbag 4 do not need to be described to who, since they are well known to those skilled in the art. It is also known that the gas generator 3 inflates (activates) the airbag 4 by rapidly supplying gas when a sensor supplies an electrical signal indicating a crash to an ignition device.

In dem beschriebenen Ausführungsbeispiel der Erfindung ist nun der Airbag 4 nicht nur als wesentlicher Bestandteil der eigent­ lichen Sicherheitsvorrichtung, sondern zugleich als Mittel zum Bewegen des zugeordneten Fahrzeuginsassen aus einer weitgehend zufälligen Ist-Position im Augenblick des Crashbeginns in eine vorgegebene Rückhalteposition ausgenutzt. Zu diesem Zweck ist der Druckmitteleinlaß a gemäß Fig. 2 über das Ventil 5 mit dem Druckspeicher 6 verbindbar, sobald der hier in der Seitentür 7 angeordnete, berührungslos, z. B. mit Mikrowellentechnik arbei­ tende Precrashsensor 8 bekannten Aufbaus den nahenden Beginn eines Seitencrashs signalisiert. Der Precrashsensor besitzt ein relativ großes Abtastfeld, charakterisiert durch den Winkel α (hier 90°). Die Sensorleiste 9, die beispielsweise aus mehreren, normalerweise einen elektrisch isolierenden Querabstand zwischen sich einschließenden Kontaktleisten besteht, dient zur vollen Aktivierung des Airbags 4.In the described embodiment of the invention, the airbag 4 is now used not only as an essential component of the actual safety device, but also as a means for moving the assigned vehicle occupant from a largely random actual position at the start of the crash into a predetermined restraint position. For this purpose, the pressure medium inlet a according to FIG. 2 can be connected to the pressure accumulator 6 via the valve 5 as soon as the one arranged here in the side door 7 , without contact, for. B. with microwave technology working pre-crash sensor 8 known structure signals the approaching beginning of a side crash. The pre-crash sensor has a relatively large scanning field, characterized by the angle α (here 90 °). The sensor bar 9 , which consists, for example, of a plurality of contact bars, which usually include an electrically insulating transverse distance between them, serves to fully activate the airbag 4 .

Sobald also mittels des Precrashsensors 8 das Bevorstehen eines Seitencrashs erfaßt wird, erfolgt durch Entladung des Druckspei­ chers 6 über den Anschluß a das Aufblasen des Airbags 4 mit einer Geschwindigkeit und einem Druck, die ein erträgliches Be­ wegen des benachbarten Fahrzeuginsassen aus einer out of posi­ tion-Stellung oder -Lage zumindest ungefähr in die vorgegebene Rückhalteposition bewirken, für die der Airbag 4 optimiert ist. As soon as the imminence of a side crash is detected by means of the pre-crash sensor 8, the airbag 4 is inflated by discharging the pressure accumulator 6 via the connection a at a speed and a pressure which is a tolerable loading due to the neighboring vehicle occupants from an out of position -Position or -position at least approximately in the predetermined retention position for which the airbag 4 is optimized.

Sollte es zu einem Fehlauslösen dieser Positionierung kommen, so besteht die Möglichkeit, durch von der Antriebsmaschine 10 des Fahrzeugs erzeugten, ggf. in einem Unterdruckbehälter 11 ge­ speicherten Unterdruck über den Anschluß b den Airbag 4 wieder in seine Ausgangslage zurückzuziehen, in der er weitgehend innerhalb des Umrisses des Dachträgers 1 verläuft. Auch ist die Möglichkeit gegeben, über den von der Antriebsmaschine 10 an­ getriebenen Kompressor 12 und das Ventil 5 den Druckspeicher 6 (der auch durch eine Patrone gebildet sein kann) wieder zu befüllen.If there is a false triggering of this positioning, there is the possibility of withdrawing the airbag 4 back into its initial position by the vacuum generated by the engine 10 of the vehicle, possibly stored in a vacuum container 11 via the connection b, in which it is largely within of the outline of the roof rack 1 . There is also the possibility of refilling the pressure accumulator 6 (which can also be formed by a cartridge) via the compressor 12 driven by the drive machine 10 and the valve 5 .

Verständlicherweise ist die Erfindung nicht auf einen derartigen Seitenairbag im Bereich des Kopfes des benachbarten Fahrzeugin­ sassen beschränkt. Bei einem anderen Einbauort des Airbags muß ggf. auch der zugeordnete Precrash-Sensor an einer anderen Stel­ le, beispielsweise in einem Stoßfänger, untergebracht werden. Auch kann bei entsprechender "gestufter" Ausbildung des Crash­ sensors auf einen Precrashsensor verzichtet werden.Understandably, the invention is not limited to such Side airbag in the area of the head of the neighboring vehicle sat limited. If the airbag is installed in a different location if necessary, the assigned pre-crash sensor at another location le, for example in a bumper. Even with a corresponding "staged" training of the crash sensors without a pre-crash sensor.

Mit der Erfindung ist demgemäß eine gattungsgemäße Sicherheits­ vorrichtung geschaffen, die sicherstellt, daß bei einem Crash der jeweilige Fahrzeuginsasse zunächst in eine vorgegebene Rück­ halteposition bewegt wird, ehe der Airbag voll aktiviert wird.With the invention is accordingly a generic security created device that ensures that in the event of a crash the respective vehicle occupant first in a predetermined return holding position is moved before the airbag is fully activated.
