Problems solved by technology

However, a disadvantage of this arrangement is that the straps have no resistance to the deployed airbag and the full energy of the airbag acts on the back side of the cover, which when opened will separate the foam layer from the trim film (moulded shell) tear together
This unhindered and firm action on the skin and the foam layer again creates the risk of separate fragments, which could injure the vehicle occupants

Embodiment Construction

[0039] figure 1 A cross-sectional view of an interior liner with an integrated airbag module is shown. In this figure the airbag cover 1 can be seen with the cover 2 and the hinge part 3 as well as the splinter protection 5 , which is fitted in a corresponding opening in the instrument panel. The hinge part 3 has a setting breaking notch 4 and an anchoring profile 6 .

[0040] The airbag cover 1 is inserted into the instrument panel frame 7 in a precisely fitted manner, wherein the contour geometry 15 of the cover 2 has a profile projection 16 which is inserted into a corresponding hollow in the region of the opening of the instrument panel frame 7 Profile 11. The opening resistance of the cover 2 is controlled by means of the contour geometry 15 and adapted to actual requirements. The dashboard frame 7 with integrated airbag cover 1 is covered with a foam layer 14 and a molded skin 9, wherein the molded skin 9 forms the visible side of the dashboard.

Abstract

The invention relates to interior panelling, especially a dashboard, comprising a built-in, separate airbag cover (1), for a motor vehicle. The opening force required to open the airbag cover (1) can be adjusted by means of a particular contour geometry (15) of the top (2) of the airbag cover (1). The invention also relates to a method for producing interior panelling comprising a built-in airbagcover (1).

Description

technical field [0001] The invention relates to a method for producing a motor vehicle interior lining with an integrated one-piece airbag cover, and to an interior lining produced according to this method. [0002] Background technique [0003] From DE 197 01 502 C2 a dashboard is known which comprises an airbag cover which is placed in a hole in the dashboard as a separate part, wherein the airbag cover is pivotable by means of a hinge arrangement Ground support, and the opening of the airbag flap takes place by means of a combined pivoting and sliding movement of the flap. In the case of this solution, it is considered a disadvantage that the appearance of the instrument panel is affected by the inserted parts. [0004] In order to avoid this disadvantage, an interior installation part of a motor vehicle, in particular a dashboard, is proposed with an integral airbag cover, in which the area covering the airbag together with the corresponding remaining area of ​​the inte...
