Abstract:
The present invention relates to an airbag cover, in particular for a motor vehicle, comprising a decor layer (1) having a decor side (2) forming an observation area, which borders the space in which the airbag deploys if the need arises, and an airbag side (3) opposite to the decor side. The decor layer further has a weakening (4) in the region of a tear line for deploying the airbag, which extends from the airbag side of the decor layer such that the decor layer is substantially intact on the decor side. The air bag cover of the present invention further has at least one second layer (2) which may be designed as spacer mesh, the second layer being attached to the airbag side of the decor layer (1) and which also has a weakening region (7) along the tear line. In order that the weakening in the decor layer (1) remains permanently invisible from the decor side (2), an intermediate layer (5) is further provided in the airbag cover of the invention which is arranged between the decor layer and the second layer. The intermediate layer is substantially intact in the region of the tear line and connected to the decor layer so that it can take up or compensate forces in the plane or parallel to the plane of the decor layer at least in the region of the weakening of the decor layer. Contrary thereto, the intermediate layer is designed such that it easily tears open substantially perpendicular to this plane under the influence of force.
