Luggage cases have been provided with expandable sections that permit the luggage case to accommodate varying amounts of the traveler's goods. These systems have included a flaccid textile gusset section, normally closed and surrounded by a zipper. The zipper can be opened fully to permit this gusset to expand. Elastically controlled gussets have also been proposed. The instant invention provides a neat, tailored accordion gusset 4 with crisscrossing elastic ribbons 22 attached to opposite rigid wire frames 8 and 10 of the expandable gusset 4, as well as a tensioned bungee cord 20 attached to the innermost edge of the center seam 26 of the expansion gusset 4. These elastic members 22 are enclosed and sealed from view by the outermost wall 6 of the luggage case 2 and an inner wall 14 defined by an elastic textile such as Spandex or the like. The resulting expansion gusset 4 can be best be built into the main packing compartment door 6 of the luggage case 2 and will expand in response to over-packing of the main packing compartment 18 by expanding the expansion gusset 4 in response to the pressure of the goods against the restoring force of the various elastic members 22.
