An integrated air bag support structure that includes a support base for attachment to the rear side of a substrate. The support base is configured to surround a door support panel and both are configured for attachment to the rear side of a substrate in an area that is pre-weakened to define an air bag deployment door in a vehicle instrument panel or a steering wheel air bag module. The upper surfaces of the support base and door support panel are attached to the rear surface of the substrate, and a test tab extends from the base that is attached to the rear surface of the substrate in the same manner as the support base and the door support panel. The test tab has an unattached extension portion for the purpose of gripping and pulling to test the integrity of the attachment without affecting the attachment of the support panel.
