Abstract

A covering member for an airbag device includes a cover body having a door section that is opened when an airbag is inflated, and a backplate integrated with the back face of the cover body. A hinge section is formed in the backplate to bend when the door section is opened. The hinge section is formed of a flexible component to allow the door section to bend easily.
