Abstract

The airbag (5) comes to its working position (I) in the event of a crash, by expanding from its folded position in the backrest. In its working position, it adopts a shape by which the passenger (4) is held in an upright position relative to the fold-out backrest (3). The airbag may cover the backrest like a mushroom. The gas store for filling the airbag may also be fitted inside the backrest. The filling of the airbag can be controlled, depending on the position of the backrest.

Description

Die Erfindung betrifft einen Airbag, welcher einer neigungsverstellbaren Rückenlehne eines Kraftwagensitzes zugeordnet ist, gemäß dem Oberbegriff des Anspruches 1.The invention relates to an airbag, which one reclining backrest of a motor vehicle seat is assigned, according to the preamble of claim 1.

Aus der DE 20 58 608 A1, die im Oberbegriff des Anspruches 1 berücksichtigt ist, ist ein Airbag an der neigungsverstellbaren Rückenlehne eines Kraftwagensitzes bekannt, der in der Rückenlehne eingefaltet liegt und bei einem Crash nach vorne in Richtung der Rückseite eines Insassen austritt und sich vor eine Nackenstütze ausbreitet. Hierdurch wird die Gefahr einer Kopf- bzw. Halswirbelverletzung des auf dem Kraftwagensitz sitzenden Insassen reduziert, da der Insasse nun auf den breiteren Airbag nahe der oberen Kante der Rückenlehne trifft und die Nackenstütze nicht mehr verfehlen kann.From DE 20 58 608 A1, which is defined in the preamble of claim 1 is taken into account is an airbag on the tilt adjustable Backrest of a motor vehicle seat known in the Backrest is folded in and in a crash in front Leaves toward the back of an occupant and faces forward spreads out a headrest. This will increase the risk of Head or cervical spine injury on the car seat seated occupants reduced because the occupant is now on the wider airbag hits near the top edge of the backrest and can’t miss the neck support.

Die Aufgabe der Erfindung besteht darin, einen gattungsgemäßen Airbag derart auszubilden, daß ein Insasse bei einer crashbedingt nach hinten abklappender Rückenlehne sicher im Sitz gehalten werden kann.The object of the invention is a generic Train airbag such that an occupant at a backrest that folds back safely due to the crash Seat can be held.

Die Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. The task is characterized by the characteristic features of the Claim 1 solved.  

Bei einem Crash des Kraftwagens kann bei in der Rückenlehnenneigung einstellbaren Sitzen, deren Rückenlehne also schwenkbar angelenkt ist, das Problem auftreten, daß die Rückenlehne durch die einwirkenden Massenkräfte der Rückenlehne und des Insassen nach hinten abklappt. Dadurch kommt der auf dem Sitz sitzende Insasse in eine liegende Position und kann vor allem dann, wenn er nicht angegurtet ist, oder wenn der obere Gurtanlenkpunkt des Schultergurtes an der Wageninnenseite und nicht am Sitz liegt, entlang der als Rampe wirkenden, flachliegenden Rückenlehne in den dahinterliegenden Innenraum geschleudert werden.In the event of a crash of the motor vehicle, in the Backrest recline adjustable seats, the backrest So is pivoted, the problem that the Backrest due to the inertial forces acting on the backrest and the occupant folds backwards. This brings it up seated occupant in a lying position and can especially if he is not wearing a seat belt or if the Upper belt pivot point of the shoulder belt on the inside of the car and not on the seat, along the ramp flat backrest in the interior behind to be flung.

Um dies zu verhindern, wird der Airbag sensorgesteuert bei einem Crash und dabei nach hinten abklappender Rückenlehne in Richtung auf den Rücken des Insassen aus der Rückenlehne heraus entfaltet und weist gasgefüllt eine Körperform auf, durch die der Insasse in einer aufrechten Position gehalten wird, die in etwa der Stellung entspricht, die der Insasse einnehmen würde, wenn die Rückenlehne noch aufgerichtet wäre. Der Schultergurt eines Sicherheitsgurtes würde dabei von der Fahrzeugseite auf Höhe der B-Säule ausgehend den Insassen weiterhin in Position halten können.To prevent this, the airbag is controlled by sensors a crash with the backrest folding backwards Direction towards the occupant's back out of the backrest unfolds and has a gas-filled body shape through which the occupant is held in an upright position in roughly corresponds to the position the occupant would occupy, if the backrest were still upright. The shoulder strap a seat belt would be from the vehicle side The height of the B-pillar continues to be in position with the occupants can hold.

Eine gute Unterstützung des Insassen kann durch eine pilzförmig vorgegebene Form des befüllten Airbags erreicht werden. In einer günstigen Anordnung ist der Gasspeicher zur Befüllung des Airbags in der Rückenlehne untergebracht.Good support for the occupant can be achieved through a mushroom shape predetermined shape of the inflated airbag can be achieved. In A favorable arrangement is the gas storage for filling the Airbags housed in the backrest.

Weitere Vorteile und Ausgestaltungen gehen aus den Unteransprüchen und der Beschreibung hervor. Further advantages and configurations come from the Subclaims and the description.  

Die Erfindung ist nachstehend anhand einer Zeichnung näher beschrieben.The invention is described below with reference to a drawing described.

Die Figur zeigt in einer Seitenansicht einen Beifahrersitz 1 in einem Kraftwagen 2, dessen Rückenlehne 3 bei einem Crash aus einer aufrechten, strichpunktiert dargestellten Position nach hinten abgeklappt ist. Damit der Insasse (Beifahrer) 4 während des Crashes nicht entlang der Rückenlehne 3 nach hinten in den Heckraum geschleudert wird, wird aus der Rückenlehne 3 ein Airbag 5 in seine Wirkstellung I entfaltet, der sich beim Abklappvorgang der Rückenlehne 3 zwischen die Rückenlehne 3 und den Insassen 4 schiebt und diesen in einer aufrechten Position hält. Der Insasse 4 wird dadurch auch weiterhin von einem nicht dargestellten Schultergurt eines Sicherheitsgurtes gehalten, welcher in üblicher Weise von der Seitenwand des Kraftwagens ausgehend über die Schulter und den Bauchraum des Insassen 4 gespannt liegt. Eine günstige Form für die Unterstützung des Insassen 4 bei abgeklappter Rückenlehne 3 ist durch eine Pilzform des Airbags 5 gegeben, da der Insasse 4 hierdurch annähernd seine Aufrichtung entsprechend seiner Haltung an der aufrechten Rückenlehne 3 beibehalten kann. Der Gasspeicher 6 zur Befüllung des Airbags 5 liegt günstigerweise zusammen mit dem gefalteten Airbag 5 in der Rückenlehne 3 aufgenommen.The figure shows a side view of a passenger seat 1 in a motor vehicle 2 , the backrest 3 of which is folded back in the event of a crash from an upright, dash-dotted position. So that the occupant (co-driver) 4 is not thrown backwards into the rear space along the backrest 3 during the crash, an airbag 5 is deployed from the backrest 3 into its active position I, which, when the backrest 3 is folded down, between the backrest 3 and the Pushes occupant 4 and holds it in an upright position. As a result, the occupant 4 is also held by a shoulder belt (not shown) of a seat belt, which, in a conventional manner, is tensioned over the shoulder and the abdomen of the occupant 4 starting from the side wall of the motor vehicle. A favorable form for supporting the occupant 4 when the backrest 3 is folded down is provided by a mushroom shape of the airbag 5 , since the occupant 4 can thereby approximately maintain his or her upright position in accordance with his posture on the upright backrest 3 . The gas reservoir 6 for filling the airbag 5 is advantageously accommodated in the backrest 3 together with the folded airbag 5 .
