发明名称 Folding cushion
摘要 An inflatable and deflatable cushion comprising an inflatable chamber to receive an inflating fluid and further including a plurality of folding means positioned on the cushion for providing a plurality of hinge lines is disclosed. Upon deflation of the cushion, the cushion collapses to enable folding along the hinge lines to enhance the flattening of the deflated cushion and to enable the repeated folding of the cushion into a defined configuration and a small size for easy storage. A valve means permits fluid communication into the chamber to define an inflated cushion and further permits fluid communication out of the chamber in order to provide a collapsed and deflated cushion. The valve means further includes a sound generating means activated by the inflating medium when the cushion is being deflated.
