Embodiment Construction

[0027] figure 1 An airbag module is shown with an airbag package 1 , a module housing 2 and a gas generator 3 . Via the fastening elements 51 , 52 the airbag module is connected to an adjacent structure, for example to the instrument panel 4 of the vehicle.

[0028] The module housing 2 forms by means of side walls 21 a housing 22 for arranging the airbag package 1 . The housing 2 additionally comprises a fastening region 23 for the gas generator 3 . In this respect, the illustrated housing 2 also illustrates a gas generator mount. However, it can be provided that the gas generator support is designed as a separate component.

[0029] The gas generator is only used as an example in the figure 1 in the icon. Essentially any gas generator can be used, where a diffuser (not shown) can be used together.

[0030] The module housing 2 furthermore forms a flange 24 for fastening the airbag module to the instrument panel 4 . The flange 24 has an opening 241 which allows the pas...

Abstract

An air bag module for a vehicle occupant restraint system is provided. The air bag module comprising an air bag package, having an air bag which is inflatable for the protection of a vehicle occupant, as well as an envelope in which the air bag is arranged, and a module casing, in which the air bag package is arranged. Here, the envelope of the air bag package comprises a first envelope part and a second envelope part and the first envelope part and the second envelope part have at least one flange section each, which are connected to each other so that at least one envelope flange protruding from the remaining air bag package is formed. It is provided that the envelope flange is spatially fixed on the module casing and / or can be spatially fixed between the module casing and an adjacent structure.

Description

technical field [0001] The invention relates to an airbag module for a vehicle occupant restraint system according to the preamble of claim 1 , and to a production method for the airbag module. Background technique [0002] It is known to pack airbags in a folded state into a foil and to create a vacuum inside the foil in order to obtain a high packing density of the airbags. For example, it is known to fold an airbag in a deep-drawn bottom foil and to weld said bottom foil together with a substantially flat top foil. Here, the problem can arise that when the airbag is deployed a large expansion of the bottom foil occurs and that the bottom foil tears before the airbag exits through the top foil. Such an undesired expansion of the bottom foil is due to the fact that the airbag can only leave the airbag module in the region of the top foil and push against the top foil accordingly. This causes the bottom foil to be under tension and similarly expand. A tearing of the botto...
