Problems solved by technology

However, such a corresponding device requires relatively high outlay, and the method also has the disadvantage that the separating medium itself is relatively expensive
In addition, the introduction of the separating medium also presents the risk of widening the defined breaking line, which may appear on the side of the decorative surface

Embodiment Construction

[0016] The decorative film consists of a decorative side 4, shown as the visible side in the vehicle compartment, and a decorative lower side 5 arranged in the direction of the airbag, in which there is a closed 3 formed by a cutout. Sealing provision disconnects line 2.

[0017] like figure 1 In the embodiment shown, the invention is realized by means of a single-layer decorative film, which is formed, for example, by simple leaching. Furthermore, the invention can also be made possible by a multi-layered decorative film produced, for example, by a double-layer casting process, in which an additional foam layer is formed on the underside of the decorative surface, thus stabilizing the entire A decorative film, and improving the tactile feeling of the decorative film. In the case of a multilayer embodiment, the decorative film is also produced from a single material type, wherein only the processing method is changed, and a decorative side is formed compactly, whereas only t...

Abstract

The invention relates to a plastic mould piece and a method thereof, through a simple way to seal a prescribed breakline designed for the open of the air bag in a decorative sheeting, the stick of the prescribed breakline is prevented, thereby ensuring a reliable air bag function. The materials of the invention is a plastic mould pieces, wherein the closure is formed in the prescribed breakline of the air bag open of the self-evolving air bag on the decorative sheeting.

Description

technical field [0001] The invention relates to a plastic molded part, which is an airbag cover for a motor vehicle, in particular a dashboard, a side panel or a cross member of a motor vehicle, and a method for producing the plastic molded part The shroud has an integrally formed air bag cover delimited by defined breaking lines on the back of the plastic moulding. Background technique [0002] Moulded parts of a motor vehicle, such as dashboards, side panels or cross-member covers, are usually composed of multiple layers and consist of at least one outer molding or trim layer and one support layer. In the case of high-end automotive parts, an intermediate layer, often embodied as polyurethane foam, is generally also arranged between the decorative layer and the support layer. [0003] A molded part constructed in this way is described, for example, in DE 10 2004 030 786 A1. [0004] If such a plastic molded part is fitted in a motor vehicle to cover an airbag, an opening...
