Embodiment Construction

[0024] figure 1 The head airbag module is shown in the installation position, wherein the airbag 1 starts from the area of ​​the A-pillar 3 and extends along the roof beam of the motor vehicle beyond the B-pillar. The head airbag module also has a gas generator not shown, and the gas generator is connected to the head airbag 1 with its gas outlet through the gas inlet on the side of the airbag.

[0025] image 3 Roughly shown in the middle, the airbag 1 is rolled into an airbag roll 9 around a reel axis extending in the longitudinal direction x of the vehicle in the inactive state, and is held on the roof rail 6 at the connection position A spaced apart from each other in the longitudinal direction x of the vehicle . Figure 2 to Figure 4 One of the connection positions A is shown in. Therefore, the airbag roll 9 is extended by the fixing plate 11, and the fixing plate is fixed on the supporting plate 15 of the roof rail 6 by the fixing element 13. in Figure 2 to Figure 4 Amo...

Abstract

The invention relates to a fastening device for fastening an airbag (1) to a support wall (15) of a vehicle, said fastening device having a fastening element (13) with a head (29) and a rod. The rod portion passes through the fixing plate (11) of the airbag (1) and the installation opening (25) of the support wall (15) in the installed state, and locks the installation opening (25) from the rear. ), wherein the head (29) of the fastening element (13) is covered by the airbag (1) in the installed state. According to the invention, the fixing plate (11) of the airbag (1) is constructed as an at least two-layer multi-layer structure with at least one fixing layer (17) and a protective layer (19). The fixing layer (17) Passed through by the rod part (23) of the fixing element (13) which can be mounted on the supporting wall (15), the protective layer covers the head (29) of the fixing element (13).

Description

Technical field [0001] The present invention relates to a fixing device for fixing an airbag on a supporting wall on the side of a vehicle body and an airbag used for the fixing device. Background technique [0002] By convention, the head airbag can extend from the A-pillar to beyond the B-pillar along the roof rail of the vehicle. The head airbag can be folded in accordion fashion and / or concealed in rolls behind the roof panel. The head airbag can be fixed to the roof beam support wall on the vehicle body side by a fixing plate configured as a fabric layer. When the head airbag module is activated, the head airbag is deployed in the manner of a curtain to isolate the vehicle occupants from the lateral structure of the vehicle that defines the interior space of the vehicle. [0003] Patent document DE 20 2004 014 219 U1 discloses a fixing device for fixing such an airbag to a support wall on the vehicle body side. It has at least one fixing element (ie, fixing clip) with a hea...
