A first stud extending from an inside trim panel surface at the closed-loop bonding section, and a second stud extends from the panel inside surface radially outward of the bonding section. A thermoplastic expandable bladder member has a welding flange along an peripheral edge which is hot-welded with the bonding section. The welding flange has a stud aperture receiving the first stud. A stepped bracket comprises a first plate overlying the welding flange and a second plate overlying the trim panel. The first plate has a first aperture receiving the first stud. The second plate has a second aperture receiving the second stud. The studs have respective re-melted heads clamping the bracket in place.
