Abstract: A trim panel for mounting to a cabin wall of a vehicle, wherein the cabin wall includes an exhauster for relieving pressure within the cabin of the vehicle and a child-seat anchor for retaining a child seat. The trim panel includes a generally rigid support structure mounted to the cabin wall. The support structure includes an opening to enable the child-seat anchor to extend therethrough. The panel further includes a first bolster panel and a living hinge. The living hinge is integrally formed with the support structure and operates to pivotally interconnect the first bolster panel to the support structure. This arrangement enables the first bolster panel to conceal the child-seat anchor and support structure opening when the bolster panel is in a closed position. More preferably, the trim panel of the present invention includes a sound-insulating device for minimizing sound infiltration from the exhauster into the cabin.
