Airbag arrangement for a vehicle occupant restraint system and a method for the production of an airbag module
First Claim
1. An airbag arrangement for a vehicle occupant restraint system, comprising:
- an airbag that comprises at least one inflatable chamber and at least one first opening;
a cover that at least partially covers the first opening of the airbag and that comprises at least one second opening, wherein the first opening and the second opening are arranged such that the chamber of the airbag is accessible through the first opening and the second opening, wherein the first opening is designed in a first layer of a first airbag material and the second opening is designed in a second layer of a second airbag material; and
at least one part which projects into the airbag through the first opening and the second opening such that the first layer and the second layer are restrained by the part projecting into the airbag in an area of the first and second openings such that a section of a rim of the first opening and a section of a rim of the second opening rest closely against the part,wherein the first opening has a non-overlapping portion that does not overlap with the second opening and the second opening has a non-overlapping portion that does not overlap with the first opening, and wherein the first opening and the second opening overlap each other at least in sections.

Abstract
An airbag arrangement includes an airbag with at least one inflatable chamber and a first opening; and a cover that at least partially covers the first opening of the airbag and that comprises a second opening. The first and second openings are designed such that the chamber of the airbag is accessible through the first and second openings. The first opening is designed in a first layer of an airbag material and the second opening is designed in a second layer of an airbag material. At least one part projects into the airbag through the first and the second opening, whereby the first and the second layer are restrained by the part projecting into the airbag in the area of the openings such that a section of the rim of the first and a section of the rim of the second opening rest closely against the part.

20. A method for producing an airbag module using an airbag arrangement, the airbag arrangement comprising an airbag that comprises at least one inflatable chamber and at least one first opening;
- a cover that at least partially covers the first opening of the airbag and that comprises at least one second opening, wherein the first opening and the second opening are arranged such that the chamber of the airbag is accessible through the first opening and the second opening, wherein the first opening is designed in a first layer of a first airbag material and the second opening is designed in a second layer of a second airbag material; and
at least one part which projects into the airbag through the first opening and the second opening such that the first layer and the second layer are restrained by the part projecting into the airbag in an area of the first and second openings such that a section of a rim of the first opening and a section of a rim of the second opening rest closely against the part, the cover being arranged in an inside of the chamber of the airbag, comprising;passing a first end of a gas generator through the first opening arranged in the first airbag material and through the second opening provided in the cover such that the gas generator takes a first position, such that, in the first position, the first end projects into the chamber of the airbag and is further away from the first opening than from the second opening and a second end of the gas generator opposing the first end is outside of the airbag; and turning the gas generator into a second position in which the first end is closer to the first opening than to the second opening. - View Dependent Claims (21)
- a cover that at least partially covers the first opening of the airbag and that comprises at least one second opening, wherein the first opening and the second opening are arranged such that the chamber of the airbag is accessible through the first opening and the second opening, wherein the first opening is designed in a first layer of a first airbag material and the second opening is designed in a second layer of a second airbag material; and
