An airbag device includes an airbag module that is located behind a multipart dashboard. An opening device opens the multipart dashboard in a manner similar to that of the mouth of a fish. An operating method for an airbag device with an airbag module located behind a multipart dashboard includes opening the dashboard in a manner similar to that of the mouth of a fish before, during, or after the triggering of the airbag device. According to another embodiment, a dashboard includes at least one fabric flap or foil flap which is integrated into the dashboard on at least one side by using detachable retaining devices in order to close an opening in the dashboard. The airbag module is positioned behind the opening in such a way that an airbag opens the retaining devices when it is triggered and emerges through the opening.
