An interior trim part with an airbag device has an airbag module (1) with a pot-shaped housing (11) for accommodating an airbag (12) which is attached at the protruding end of a firing passage (24) to a dimensionally stable support (2). An opening section (23) for the deployment of the airbag is predetermined in the support (2) by means of tear lines (21) and/or hinge lines. The problem arises of preventing, by means of a simple measure, the opening section (23) from tearing off during the deployment of the airbag (12). For this purpose, it is proposed that a first section (41) of a retaining band (4) is attached to the opening section (23), said retaining band running within the firing passage (24) as far as the base of the airbag module (1) and being fastened there. It is additionally proposed, in the sense of an even more substantial improvement, that the attachment of the retaining band (4) to the opening section (23) is placed in the vicinity of the hinge line and aligned therewith, and the retaining band (4) is guided approximately tautly through the firing passage (24).
Interior trim part with an airbag device, having an airbag module (1) with a pot-shaped housing (11) for accommodating an airbag (12) and a dimensionally stable support (2) with an opening section (23) defined by material or structural weakenings applied along tear lines (21) and with a firing passage (24) which protrudes on one side from said support and is intended for aligning the deployment of the airbag (12) with the opening section (23), wherein the airbag module (1) is arranged at the protruding end of the firing passage (24), characterized in that a first section (41) of a retaining band (4) is attached to the opening section (23), said retaining band running from there within the firing passage (24) as far as the base of the airbag module (1) and being fastened there.
