ABSTRACT:
An interior panel assembly and an airbag device are provided that are equipped with structure for preventing an interior panel and a backing plate from becoming detached from each other. In one form, when an inflator discharges gas, movable door-frame members are moved (lifted) upward by being pushed upward by an inflating airbag. An instrument panel ruptures along a peripheral tear line, causing a door portion to be cut and separated from the surrounding instrument panel. Grooves serving as rupturable sections extend along joint sections between backing plates and leg plates of the movable door-frame members. When the backing plates of the movable door-frame members open outward together with the door portion, the grooves rupture to cause the backing plates to become partially separated from the leg plates. At the sections of the backing plates partially separated from the leg plates, the backing plates become substantially flat as a result of the partial separation from the leg plates.
