Abstract

The inflatable body (5) forms a buffer protruding beyond the outline of the vehicle. It is accommodated between the outer skin (1) of the vehicle and an inner base (4), the latter consisting of beams or reinforcing plates, and unfolds between them. Part of the skin not solidly secured to the chassis can move for a limited distance away from the vehicle, and protects the inflatable body. The latter also distributes the impact over a wide surface of the stiffening members behind. Outward movement of the skin can be allowed by unlocking the joint between it and the chassis, and can be limited by belts between the two.

Description

Besonders beim Bau von Automobilen geringer Abmessungen und damit auch geringer seitlicher Freiheit zwischen Türe und Passagier ist der Schutz vor seitlichen Zusammenstößen von erheblicher Bedeutung.Especially when building automobiles of small dimensions and therefore also The protection against is little lateral freedom between door and passenger side collisions of considerable importance.

Diesem Schutz - besonders bei seitlichen Stößen oberhalb des Türschwellers - wird üblicherweise durch verstärkte Innenkonstruktion der Türen oder durch ihre Verstärkung mit Traversen begegnet.This protection - especially in the event of side impacts above the door sill - is usually due to reinforced internal construction of the doors or their Reinforcement met with trusses.

Problematisch bleibt dabei, daß sich der eigentliche Pufferraum zwischen Stoßursache und Fahrzeug, also außerhalb des Fahrzeugs, nicht vergrößern läßt. Durch Einbau eines Airbags in die Türe, der sich zumindest zwischen Türe und Passagier einschiebt, sobald ein seitlicher Aufschlag erfolgt ist, lassen sich Verletzungen in gewissem Umfang abmildern; es bleibt jedoch bei dem geringen Pufferraum von etwa 15-25 cm zwischen dem Körper des Fahrgastes und dem Außenblech der Türe bzw. auch der türlosen Fahrzeugwandung.The problem remains that the actual buffer space between The cause of the impact and the vehicle, i.e. outside the vehicle, cannot be enlarged. By installing an airbag in the door, which is at least between the door and Passenger pushes in as soon as there is a side impact To some extent mitigate injuries; however, it remains the low one Buffer space of about 15-25 cm between the passenger's body and the Outer panel of the door or the doorless vehicle wall.

Die erfindungsgemäße Anordnung kann diesen Pufferraum bei jedem Fahrzeug um mindestens 30 cm erweitern, ohne daß das Fahrzeuggewicht vergrößert würde oder neuartige Technologien angewendet werden müßten.The arrangement according to the invention can accommodate this buffer space in any vehicle expand by at least 30 cm without increasing the vehicle weight or new technologies would have to be applied.

Grundsätzlicher Aufbau einer erfindungsgemäßen VorrichtungBasic structure of a device according to the invention

Fig. 1a zeigt einen Längsschnitt durch eine Fahrzeugwandung oder Fahrzeugtüre (übliche Einbauten wie Fensterkurbeln etc. sind nicht eingezeichnet):
das äußere Türblech (1) ist mit einem Türrahmen (1a) nicht fest verschweißt, sondern mit entriegelbaren Aufhängungen (2) befestigt. Diese können auch durch Halteteile mit je einer Sollbruchstelle gebildet werden. Zusätzlich ist das Außenblech mit einer ausreichenden Anzahl von beweglichen Laschen (3) befestigt - etwa aus dem Material, das für Sicherheitsgurte verwendet wird. 1 a shows a longitudinal section through a vehicle wall or vehicle door (customary installations such as window cranks etc. are not shown):
the outer door panel ( 1 ) is not firmly welded to a door frame ( 1 a), but is fastened with unlockable suspensions ( 2 ). These can also be formed by holding parts, each with a predetermined breaking point. In addition, the outer panel is fastened with a sufficient number of movable tabs ( 3 ) - for example from the material that is used for seat belts.

Zum Fahrzeuginnenraum hin sind kastenförmige Längsstreben (4) eingesetzt. Zwischen diesen und dem Außenblech (1) befindet sich ein Luftsack (5), der aus widerstandsfähigem Material besteht und in der gezeichneten Darstellung noch nicht aufgeblasen ist. Der Luftsack kann durch eine der bekannten Methoden, eventuell auch durch eine definierte Sprengladung, aufgeblasen werden. Um ein schlagartiges Platzen des gesamten Luftsacks bei partieller Überbeanspruchung durch einen Aufprall zu vermeiden, kann er in mehrere Kammern eingeteilt sein, die zwar ein gleichzeitiges Aufblasen aller Einzelkammern erlauben, danach aber durch die eingesetzten Rückschlagklappen die Kammern weitgehend unabhängig machen. Teil (6) stellt eine übliche Innenraumverkleidung dar, (7) eine optionale Abdeckung zwischen Streben (4) und Luftsack (5), um eine noch bessere Druckverteilung zu erzielen. Box-shaped longitudinal struts ( 4 ) are used towards the vehicle interior. Between this and the outer sheet ( 1 ) there is an airbag ( 5 ), which consists of a resistant material and is not yet inflated in the drawing. The airbag can be inflated by one of the known methods, possibly also by a defined explosive charge. In order to avoid a sudden burst of the entire airbag in the event of partial overstress due to an impact, it can be divided into several chambers, which allow simultaneous inflation of all individual chambers, but then make the chambers largely independent through the non-return flaps used. Part ( 6 ) represents a common interior lining, ( 7 ) an optional cover between struts ( 4 ) and airbag ( 5 ) in order to achieve an even better pressure distribution.

Fig. 1c stellt eine bevorzugte Verbindung der Längsstreben (4) mit dem Fahrzeugchassis dar. Sie stellt sicher, daß die Streben bei starkem Seitendruck von außen nach innen eine stabile Verbindung zum Chassis haben, um den Seitendruck auf das Chassis umzulenken, aber beim Öffnen - also von innen nach außen - keinen Sperreffekt ausüben. Fig. 1c represents a preferred connection of the longitudinal struts ( 4 ) to the vehicle chassis. It ensures that the struts have a strong connection from outside to inside with strong side pressure to divert the side pressure onto the chassis, but when opening - So from the inside out - do not have a blocking effect.

Arbeitsweise der SchutzvorrichtungOperation of the protection device

Ausgelöst wird der Aufblasvorgang bevorzugt durch eine Annäherungserkennung, mit der sich die Annäherung größerer Massen zuverlässig erfassen läßt. Beim Erreichen einer Grenzgeschwindigkeit für die Quer-Annäherung von Objekten (oder auch für die Querannäherung des Fahrzeugs an stehende Objekte) wird der Luftsack aufgeblasen. Er drückt das Außenblech der Türe - oder einen geeigneten Teil der Fahrzeugwand - nach außen.The inflation process is preferably triggered by proximity detection, with which the approximation of larger masses can be reliably detected. At the Reaching a limit speed for the cross-approach of objects (or also for the cross approach of the vehicle to standing objects) the airbag inflated. He pushes the outer panel of the door - or one suitable part of the vehicle wall - to the outside.

Fig. 1b zeigt die erfindungsgemäße Anordnung im aktivierten Zustand:
der Luftsack (5) hat sein volles Volumen erreicht und beim Aufblasen das Blech (1) als "Schutzschild" so weit nach außen, zur Gefahr hin, gepreßt, wie es die Länge der Laschen (3) erlaubt. Das Sandwich aus Außenhaut (1), Luftsack (5) und innenseitigen Streben (4) bewirkt eine gegenseitige Schutzfunktion: die Außenhaut verhindert die Zerstörung des Luftsacks und verteilt den Druck des Aufpralls, der Luftsack wiederum nimmt diesen großflächigeren Druck auf und gibt ihn gepuffert und noch besser verteilt an die Innenstreben (4) weiter. Über diese wird der Druck durch eine Verriegelung nach Fig. 1c als Zugkraft an das Fahrzeugchassis, bevorzugt in Längsrichtung, weitergegeben. FIG. 1b shows the arrangement of the invention in the activated condition:
the airbag ( 5 ) has reached its full volume and, when inflated, the sheet ( 1 ) is pressed as a "protective shield" as far outwards, towards the danger, as the length of the tabs ( 3 ) allows. The sandwich of outer skin ( 1 ), air bag ( 5 ) and inner struts ( 4 ) has a mutual protective function: the outer skin prevents the destruction of the air bag and distributes the pressure of the impact, the air bag in turn absorbs this larger pressure and gives it buffered and even better distributed to the inner struts ( 4 ). Via this, the pressure is transmitted as a tensile force to the vehicle chassis, preferably in the longitudinal direction, by a lock according to FIG. 1c.
