Abstract

The invention relates to a collision protection device, especially for passengers in vehicles, especially motor vehicles, and again especially for front-seat passengers, consisting of an air-bag in which the air-bag made, e.g., of a polyamide fabric with or without a coating consists of a cover section having a gas inlet aperture in the region of which there may be one or more inserts (e.g. flame protection), and two side sections, in which the gas inlet is in the overlap at the cover ends and is designed for connection to a gas generator or gas generator housing. The invention essentially consists in that the joint (7') of the two cover ends (6) is at the same time the reinforcement of the gas inlet (1') and the securing component for inserts (e.g. flame protection (4')), the joint being annular around the gas inlet.

Polyamidgewebe) mit oder ohne Beschich¬ tung wiederum aus einem Manteltei l besteht, welches eine Gas¬ eint römö fnung aufweist, in deren Bereich gegebenenfalls ein oder mehrere Einbautei le (z.B. Flammschutz) sich befinden, und zwei Seitentei len; wobei die Gaseinströmöffnung in der Überlappung der RanteLenden liegt und für den Anschluß an einen Gasgenerator bzw. an ein Gasgeneratorgehäuse vorgesehen ist.The invention relates to a safety device, in particular for occupants of vehicles, in particular motor vehicles, in particular on the passenger side, consisting of a cushion or cover cap, airbag (airbag) ), Mounting parts (eg holding plate), electronic or mechanical devices and gas generator; the airbag made of fabric (for example polyamide fabric) with or without a coating in turn consists of a jacket part which has a gas inlet opening, in the area of which there may be one or more installation parts (for example flame protection), and two side parts; wherein the gas inflow opening lies in the overlap of the RanteLenden and is intended for connection to a gas generator or to a gas generator housing.
Luftsäcke für das Airbagsystem in Kraftfahrzeugen auf der Bei¬ fahrerseite gemäß dem Stand der Technik sind konstruktiv mit innen- oder außenliegenden Generatoren ausgestattet. Um eine kostengü'nstige Montage des Generators zu ermöglichen, muß eine entsprechende Öffnung am Luftsack gemäß DE-C-40 10 796 vor¬ handen sein.Air bags for the airbag system in motor vehicles on the passenger side according to the prior art are structurally equipped with internal or external generators. In order to enable inexpensive assembly of the generator, a corresponding opening on the airbag according to DE-C-40 10 796 must be available.
Darüber hinaus muß die konstruktive Gestaltung so sein, daß eine prozeßsichere und kostengünstige Fertigung möglich ist.In addition, the structural design must be such that a reliable and cost-effective production is possible.
Gemäß dem Stand der Technik werden ferner jewei ls Verbindungen oder Fügestel len bzw. Fügebereiche für die Festlegung der Mantelenden, für die Verstärkung der Gaseinströmöffnung sowie gegebenenfalls die Befestigung von Einbautei len vorgesehen. Die Aufgabe der Erfindung besteht nun darin, diese vorge¬ nannten Konstruktionselemente so zusammenzufassen, daß sie in einem Arbeitsgang ausgeführt werden können.According to the prior art, connections or joining points or joining areas are also provided for the fixing of the jacket ends, for the reinforcement of the gas inflow opening and, if appropriate, the fastening of built-in parts. The object of the invention is to summarize these construction elements so that they can be carried out in one operation.
Die Lösung dieser Aufgabe besteht nun gemäß Kennzeichen des Anspruchs 1 darin, daß die Verbindung beider Mantelenden zugleich die Verstärkung der Gaseinströmöffnung sowie gegebenenfalls die Befestigung von Einbautei len ist, wobei die Verbindung die Gaseinströmöffnung ringförmig umläuft.The solution to this problem consists, according to the characterizing part of claim 1, in that the connection of both jacket ends is at the same time the reinforcement of the gas inflow opening and, if appropriate, the attachment of built-in parts, the connection circulating around the gas inflow opening.
Hinsichtlich der Verbindung kommen zweckmäßigerweise folgende Varianten zur Ausführung:With regard to the connection, the following variants are expediently carried out:
- Die Verbindung besteht aus einer oder mehreren Naht/Nähten, wobei die Nähte insbesondere Doppelsteppstichnähte oder Doppe l ket tenst i c hnäht e oder Schweißnähte sind.- The connection consists of one or more seams / seams, the seams being, in particular, double lockstitch seams or double chain stitch seams or weld seams.
- Die Verbindung besteht aus punkt fö rmi gen oder kleinflächigen Schweißstel len.- The connection consists of spot-shaped or small-area welds.
Die Erfindung wird nun anhand von Ausfüh rungsbei spi e len unter Bezugnahme auf schematische Zeichnungen erläutert. Es zeigen:The invention will now be explained with reference to exemplary embodiments with reference to schematic drawings. Show it:
