Abstract

The application relates to a fastening of a gas cushion unit, which is assigned to a passenger seat, in a vehicle, the gas cushion unit having a casing which can be pushed into a frame formed by parts which are fixed to the vehicle and can be fixed there. In order to permit rapid assembly with as few individual fastening parts as possible, provision has been made according to the invention for a central clamping screw which is arranged approximately in the centre to be provided which penetrates frame and casing on their top and bottom sides and acts on two bridge elements which in each case rest in a clampable fashion on the outside of the top and bottom sides of the frame and in each case have two catching cams which are arranged on both sides of the clamping screw, are directed towards the casing, penetrate holes in the frame in the clamped condition of the bridge elements and engage into apertures in the casing in a position-securing manner.

Die Erfindung betrifft eine Befestigung einer einem Mitfahrerplatz zugeordneten Gaskissen-Einheit in einem Kraftwagen, wobei die Gaskissen-Einheit ein Gehäuse aufweist, das in einen von fahrzeugfesten Teilen gebildeten Rahmen einschiebbar und dort festlegbar ist. The invention relates to a fastening of a passenger seat associated gas cushion unit in a motor vehicle, the gas cushion unit has a housing which can be pushed into a frame formed by parts fixed to the vehicle and can be specified there.

Derartige Gaskissen-Einheiten sind beispielsweise durch die US-PS 41 91 392 und durch die US-PS 37 91 671 bekannt. Such gas cushion units are for example by the US-PS 41 91 392 and from US-PS 37 91 671 known.

Neuere Gaskissen-Einheiten haben im allgemeinen einen pyrotechnischen Treibsatz, der dem Erzeugen des zum Füllen des Gaskissens benötigten Gases dient. Wegen der im Umgang mit einem derartigen Treibsatz gebotenen Vorsicht wird angestrebt, den Einbau der Einheit in einem Kraftwagen erst am Ende der Endmontage des Fahrzeugs vorzunehmen, umso einer Fehlauslösung z. B. durch einen ungewollten Kurzschluß vorzubeugen. Newer gas cushion units generally have a pyrotechnic one Propellant used to generate the gas required to fill the gas bag. Because of the caution required when handling such a propellant charge, the aim is to the installation of the unit in a motor vehicle only at the end of the final assembly of the vehicle make, all the more to a false trip z. B. to prevent an unwanted short circuit.

Aus diesem Grunde soll die gesamte Gaskissen-Einheit mit möglichst wenig einzelnen Befestigungsteilen versehen sein und in kurzer Zeit einfach und zuverlässig im Fahrzeug montiert werden können.For this reason, the entire gas cushion unit should be as close as possible be provided little individual fastening parts and in a short time easy and can be reliably installed in the vehicle.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, eine gattungsgemäße Gaskissen-Einheit in dieser Hinsicht zu optimieren. The present invention was therefore based on the object of providing a generic Optimize the gas cushion unit in this regard.

Dieses wird erfindungsgemäß dadurch erreicht, daß eine etwa mittig angeordnete, zentrale Spannschraube vorgesehen ist, die Rahmen und Gehäuse an ihrer Ober-und Unterseite durchdringt, und die auf zwei Brückenglieder einwirkt, die jeweils außen auf der Ober- und Unterseite des Rahmens spannbar aufliegen, und die jeweils zwei beidseits der Spannschraube angeordnete, zum Gehäuse gerichtete Rastnocken aufweisen, die im gespannten Zustand der Brückenglieder Löcher im Rahmen durchdringen und in Öffnungen im Gehäuse lagesichernd eingreifen. This is achieved according to the invention in that an approximately centrally arranged, central clamping screw is provided, the frame and housing on their Penetrates top and bottom, and which acts on two pontics, each rest on the outside on the top and bottom of the frame, and each two locking cams arranged on both sides of the clamping screw and directed towards the housing have, which penetrate holes in the frame when the bridge members are tensioned and engage in openings in the housing to secure the position.

Vorteilhafte Ausgestaltungen der Erfindung sind den weiteren Patentansprüchen zu entnehmen. Advantageous refinements of the invention are set out in the further claims refer to.

Der Gegenstand der Erfindung soll im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden. In der Zeichnung zeigt F i g. 1 eine teilweise aufgebrochene Rückansicht einer eingebauten Gaskissen-Einheit, und Fig.2einen Schnitt nach der Linie ll-ll in Fig. 1. The object of the invention is to be based on one in the Drawing illustrated embodiment will be explained in more detail. In the drawing shows Fig. 1 is a partially broken away rear view of a built-in gas cushion unit; and FIG. 2 shows a section along the line II-II in FIG. 1.

Die Gaskissen-Einheit umfaßt ein als Gußteil ausgebildetes Gehäuse 1, das in einen aus Blech bestehenden, fahrzeugfesten Rahmen 2 vorzugsweise im Bereich einer nicht näher dargestellten Armaturentafel eines Kraftwagens eingeschoben ist. The gas cushion unit comprises a housing designed as a cast part 1, which is made of sheet metal, vehicle-fixed frame 2, preferably in the area a not shown dashboard of a motor vehicle is inserted.

Der Festlegung des Gehäuses 1 im Rahmen 2 dient eine zentrale Spannschraube 3, die mit zwei Brückengliedern 4 und 5 zusammenwirkt, die außen auf dem Rahmen 2 aufliegen und diesen gegen das Gehäuse 1 drücken. Dabei weist das dem Schraubenkopf nahe Brückenglied 4 ein Durchgangsloch und das gegenüberliegende Brückenglied 5 ein Gewinde auf. A central clamping screw is used to fix the housing 1 in the frame 2 3, which cooperates with two bridge members 4 and 5, the outside of the frame 2 and press it against the housing 1. This points to the screw head near the bridge member 4 a through hole and the opposite bridge member 5 a thread.

Die Brückenglieder 4 und 5 liegen jeweils mit einem zentralen Bereich 4a und 5a und zwei zu diesen parallelen, jedoch in der Höhe versetzten Endabschnitten 4b und 5b auf dem Rahmen auf, und die zentralen Bereiche 4a und 5a und die beiden Endabschnitte 4b und 5b der Brückenglieder 4 und 5 sind jeweils durch Zwischenabschnitte 4c und 5c miteinander verbunden. Im Bereich der Brückenglieder 4 und 5 sind Rahmen 2 und Gehäuse 1 an deren Form angepaßt. The bridge members 4 and 5 each have a central area 4a and 5a and two end sections parallel to these, but offset in height 4b and 5b on the frame, and the central areas 4a and 5a and the two End portions 4b and 5b of the bridge members 4 and 5 are separated by intermediate portions, respectively 4c and 5c connected to each other. In the area of the bridge members 4 and 5 there are frames 2 and housing 1 adapted to their shape.

Von jedem Endabschnitt 4b und 5b ragt ein zum Gehäuse 1 hin gerichteter Rastnocken 6 ab, der ein Loch im Rahmen 2 durchdringt und in eine Öffnung 7 im Gehäuse 1 lagesichernd eingreift und so eine Bewegung der Gaskissen-Einheit 8 in Fahrzeuglängs- und Querrichtung sicher verhindert. From each end section 4b and 5b a one directed towards the housing 1 protrudes Latching cam 6, which penetrates a hole in the frame 2 and into an opening 7 in the housing 1 engages securely in position and thus a movement of the gas cushion unit 8 in the vehicle longitudinal and cross direction reliably prevented.

Claims (1)

Um das Gehäuse 1 bei vormontierter, aber noch nicht angezogener Spannschraube 3 von vorne in den Rahmen 2 einschieben zu können, weist dieses einen nach hinten offenen Führungskanal 9 für die Spannschraube 3auf. Around the housing 1 with the clamping screw pre-assembled but not yet tightened 3 to be able to slide into the frame 2 from the front, this one points to the rear open guide channel 9 for the clamping screw 3.
