Abstract

The safety device comprises the engine with an air filter housing and located under the bonnet. At least parts of the air filter housing (9) are located between the engine (2) and underside of the bonnet (6), and these parts are constructed as a crashbox absorbing energy when deforming.

Description

Die Erfindung betrifft eine Sicherheitseinrich­ tung als Fußgängeraufprallschutz an Kraftfahrzeugen gemäß dem Oberbegriff des Patentanspruches.The invention relates to a security device tion as pedestrian impact protection on motor vehicles in accordance the preamble of the claim.

Mit DE 198 53 340 A1 ist eine Sicherheitsein­ richtung als Fußgängeraufprallschutz am Vorderwagen eines Kraftfahrzeuges beschrieben, bei der eine Fronthaube von einem Energie absorbierenden Randteil umgeben ist, wel­ ches sich bei einem Aufprall auf einen Fußgänger ver­ formt.DE 198 53 340 A1 is a safety device Direction as pedestrian impact protection on the front of one Motor vehicle described in which a front hood of is surrounded by an energy absorbing edge part, wel in the event of an impact on a pedestrian shaped.

Eine solche Maßnahme kann jedoch einen auf die obere Seite der Motorhaube aufschlagenden Fußgänger nicht schützen, da sich der Antriebsmotor als harte und unnach­ giebige Masse aus Packagegründen sehr nahe unterhalb der Motorhaube befindet und damit der Motorhaube in diesem Bereich keinen Raum zum Ausweichen lässt. Auch wenn es gelingen würde, zwischen Motorhaube und Oberkante An­ triebsmotor Raum zu belassen, dann wäre ein Fußgängerauf­ prallschutz nur sehr bedingt gegeben, da die Motorhaube in ihrer Fläche relativ leicht nachgibt, ohne wesentlich Energie absorbieren zu können und dann bei Anschlag auf die Masse des Motors praktisch starr reagiert, so dass sich dann eine unzulässig hohe Aufprallkraft ergibt. However, such a measure can affect the pedestrian hitting the top of the hood protect because the drive motor turns out to be hard and unrelenting mass for package reasons very close below the Bonnet is located and thus the bonnet in this Area leaves no room for evasion. Even if it would succeed between the bonnet and the upper edge to leave the drive motor room would be a pedestrian walk Impact protection is only given to a very limited extent since the bonnet yields relatively easily in its area without significant To be able to absorb energy and then when it hits the mass of the engine reacts practically rigid, so that then an impermissibly high impact force results.  

Um dies zu vermeiden, wurde auch schon vorge­ schlagen, die Motorhaube als Flächendeformationselement auszubilden. Dies erfordert jedoch einen erhöhten Bau­ raumaufwand über die gesamte Fläche der Motorhaube und erhebliche Bauaufwendungen.In order to avoid this, it was already featured beat the bonnet as a surface deformation element train. However, this requires an increased construction space over the entire area of the hood and considerable construction costs.

Der Erfindung liegt die Aufgabe zugrunde, eine Sicherheitseinrichtung als Fußgängeraufprallschutz zu schaffen, die bei einem Aufprall eines Fußgängers oder Radfahrers auf die Fläche der Motorhaube die Situation entschärft, wobei die Motorhaube selbst ohne zusätzlichen Bauraum und Bauaufwand gegenüber üblichen Motorhauben ausgeführt werden kann.The invention has for its object a Safety device as pedestrian impact protection too create that in the event of a pedestrian or impact Cyclist on the surface of the hood the situation disarmed, the hood itself without additional Space and effort compared to conventional hoods can be executed.

Die Erfindung löst diese Aufgabe mit den Merk­ malen des Patentanspruches.The invention solves this problem with the Merk paint the claim.

Durch die Anordnung von als Crashbox ausgebil­ deten Teilen eines ohnehin im Fahrzeug erforderlichen Luftfilterkastens zwischen der Unterseite der Motorhaube und der Oberkante des Motors wird sich im Falle eines Aufpralls die bei relativ geringer Krafteinwirkung ein­ beulende Motorhaube auf die darunter befindliche Crash­ box, gebildet vom Luftfilterkasten, auflegen. Die Crash­ box, die in an sich bekannter Weise konstruktiv auf einen definierten Kräfteverlauf bei der Deformation ausgelegt ist, wird die Aufprallkräfte auf die Motorhaube über den Verformungsweg in der Mehrzahl aller Fälle auf einem zu­ lässigen Wert halten. Da der Luftfilterkasten funktions­ bedingt ohnehin als Hohlteil ausgebildet sein muss, ist es relativ einfach, den vorhandenen Hohlraum als Verfor­ mungsweg bei einem Crash zu nutzen.By the arrangement of trained as a crash box parts of an already necessary in the vehicle Air filter box between the underside of the hood and the top edge of the engine will be in the case of a Impacts with relatively little force bulging bonnet on the crash underneath on the air filter box. The crash box, which in a known manner constructively on a defined course of forces during the deformation is the impact forces on the hood over the Deformation path in one case in the majority of all cases hold casual value. Because the air filter box is functional must be designed as a hollow part anyway it is relatively easy to deform the existing cavity in a crash.

Ein Ausführungsbeispiel der Erfindung ist nach­ stehend anhand einer Zeichnung näher beschrieben. An embodiment of the invention is according to standing described with reference to a drawing.  

Die Abbildung zeigt stark schematisiert einen Schnitt quer durch ein Kraftfahrzeug im Bereich eines vorn liegenden Motorraumes. Im Motorraum 1 ist ein An­ triebsmotor 2 sowie ein Getriebe 3 untergebracht. Der Mo­ torraum 1 ist seitlich von den Radhausblechen 4 und den Kotflügeln 5 begrenzt. Nach oben ist der Motorraum 1 mit einer Motorhaube 6 abgeschlossen, die in üblicher Weise an Teilen der Karosserie angelenkt ist. Antriebsräder 7 sind über Gelenkwellen 8 mit dem Getriebe 3 verbunden. Zwischen der Motorhaube 6 und der Oberkante des Antriebs­ motors 2 ist ein für die Motorfunktion ohnehin erforder­ licher Luftfilterkasten 9 angeordnet. Der Luftfilterkas­ ten 9 ist seitlich vom Antriebsmotor 2 mit Anschlüssen 10 für die Luftschläuche versehen. Wesentliche Teile des hohlen Körpers des Luftfilterkastens 9 sind als Crashbox ausgebildet, und zwar in der Art, dass senkrecht auf die Fläche der Motorhaube 6 auftretende Kräfte, welche zu ei­ ner Verformung der Motorhaube 6 bis zum Luftfilterkasten 9 führen, bei weiterer Verformung in einer definierten Weise abgestützt werden, wobei sich die als Crashbox aus­ gebildeten Teile des Luftfilterkastens 9 bei gleichzeiti­ ger Energieaufnahme verformen. Als Verformungsweg steht dabei der ohnehin aus Funktionsgründen im Luftfilterkas­ ten 9 erforderliche Hohlraum zur Verfügung. The figure shows a highly schematic section through a motor vehicle in the area of a front engine compartment. In the engine compartment 1 to a drive motor 2 and a gear 3 is housed. The Mo torraum 1 is laterally limited by the wheel house panels 4 and 5 fenders. The engine compartment 1 is closed at the top by a hood 6 , which is articulated in the usual way on parts of the body. Drive wheels 7 are connected to the transmission 3 via cardan shafts 8 . Between the hood 6 and the upper edge of the drive motor 2 , an air filter box 9 which is required anyway for the engine function is arranged. The air filter box 9 is provided laterally from the drive motor 2 with connections 10 for the air hoses. Essential parts of the hollow body of the air filter box 9 are designed as a crash box, in such a way that forces occurring perpendicular to the surface of the bonnet 6 , which lead to a deformation of the bonnet 6 to the air filter box 9 , upon further deformation in a defined Are supported in such a way that the parts formed as a crash box of the air filter box 9 deform while simultaneously absorbing energy. As a deformation path, the cavity required anyway for functional reasons in the air filter box 9 is available.
