Abstract
The invention relates to an interior trim panel for motor vehicles fitted with an airbag. Said panel consists of a dimensionally stable supporting member (3) with a film cover (1) on its visible face, and is provided with a tear-open airbag penetration area for expansion of airbag at the point where the airbag is installed (9'). The airbag penetration area is defined by notches (5) in the supporting member (3). The support member has a guide channel (3'), which is integrally formed at the rear, for the expanding airbag. The opening (12) of this channel is covered by the supporting member and the film cover on the visible face which is devoid of any markings. The notches of the guide-channel opening define a pocket-like opening penetration area during airbag expansion. Said notches form a pattern of lines consisting of a center line and side lines which branch off parallel to or diagonally from the center line. A cutting metal sheet (4) is arranged in the line pattern area between the supporting element and the cover. It has cutting edges, which when oriented towards the cover, coincide with the line pattern of the notches.
