ABSTRACT:
A lower support bracket has an integral back wall, pair of side walls and a bottom plate with a through bore. An elastomeric spacer is mounted axially above and below the bottom plate bore and an adjuster device is axially mounted below the lower elastomeric spacer. The bracket is held in place by a bolt through the bore to an aircraft frame structure. The back wall is attached to an escutcheon plate which is in turn attached to a lower portion of an aircraft interior panel. The upper support bracket has a mounting plate attached to an aircraft fuselage frame structure. A pivoting arm at a first end is spaced from the mounting plate by an elastomeric gasket and at a second end is attached to a panel bracket attached to an upper portion of the interior panel so that the interior panel is spaced apart from the aircraft fuselage frame structure.
