Abstract

An airbag covering cap including a support layer and a covering layer of different elasticities, having at least one tear-off line along which the airbag covering cap tears open when the airbag is deployed. The covering layer is weakened by a groove in the region of the tear-off line and the support layer extends into this groove. The covering layer has a section adjacent to the section of the support layer, which extends into said support layer. The edge between the sections of the support and covering layers, each extending into the other layer is configured as a tear-off edge.
