Abstract
An airbag cover may be configured to tear along weakening lines during deployment of an airbag. The airbag cover may comprise a carrier for the airbag and a decorative layer arranged on the carrier. The decorative layer may include a primary weakening line and a secondary weakening line, where the primary weakening line and the secondary weakening line may be configured to fracture when the airbag deploys. The primary weakening line may extend in a longitudinal direction, the secondary weakening line may extend in the longitudinal direction, the primary weakening line and the secondary weakening line may be separated by a distance extending in a direction perpendicular to the longitudinal direction, and the primary weakening line and the secondary weakening line may be separated by a non-weakened section. Methods for producing a weakening region in an airbag cover may also be provided.
