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

The invention relates to an airbag module for a vehicle occupant restraint system, having an airbag pack (1) which has an airbag (14), inflatable in order to protect a vehicle occupant, and which has a jacket (11, 12) in which the airbag (14) is arranged, and having a module housing (2) in which the airbag pack (1) is arranged. Here, the jacket (11, 12) of the airbag pack (1) comprises a first jacket part (11) and a second jacket part (12), and the first jacket part (11) and the second jacket part (12) have in each case at least one flange section (111, 121) which are connected to one another so as to form at least one jacket flange (6) which projects from the rest of the airbag pack (1). It is provided that the jacket flange (6) is spatially fixed to the module housing (2) and/or can be spatially fixed between the module housing (2) and an adjacent structure (4). The invention also relates to a vehicle having an airbag module of said type, and to a method for producing an airbag module.

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...
