Embodiment Construction

[0017] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0018] FIG. 1 illustrates an airbag cover 1 with a trim ring 2 as trim part 2 . The trim ring 2 is attached to the airbag protective cover 1 in a conventional manner. The airbag cover 1 is provided with tearable edges 3-7 so that when the airbag is triggered the airbag cover can be torn at areas 8-11. The decorative part 2 has predeterminable breaking points at the positions of the tearable edges 3-7, the breaking points being distributed in such a way that the tearable edges 3-7 extend transversely through the decorative ring 2 at these positions. As a result, the trim ring 2 is torn together with the tearable edges 3-7 of the airbag protective cover 1, so that when the protective cover 1 is torn, about a quarter of the trim ring 2 remains in its respective area. In another version of the decorative ring 2 or the protective cover 1 , other parts of the d...

Abstract

A decorative element for cover caps of airbag modules is provided. The decorative element includes predetermined breaking points and / or bending points. As a result of the predetermined breaking points and / or bending points, the decorative element tears together with the cover cap when an airbag is deployed.

Description

technical field [0001] The invention relates to a trim part or logo for an airbag module protective cover. Background technique [0002] Protective covers for airbag modules, especially for drivers, are often provided with trim parts. In the past, they have always been manufactured largely from metals such as aluminum, or from plastics as rigid parts and additionally provided with a decorative metallic coating. In the event of a crash, these trim parts cause the airbag cover to harden in the area where the airbag deploys. In the event of a crash, these hard and heavy trim components can cause considerable injury to passengers. Also, if the airbag is triggered at low temperatures, there will be a risk of shattering, especially with regard to the shattering of the trim parts trimmed with gold filigree. [0003] German Patent Publication No. 101 00 747 A1 (hereby referenced in its entirety and incorporated herein) shows an airbag cover to which a flexible trim sheet is faste...
