    • 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.
    • 一种可膨胀和可放气的衬垫,其包括一个可充气室,用于容纳充气流体,并且还包括多个折叠装置,该多个折叠装置位于衬垫上,用于提供多个铰链线。 在缓冲垫紧时,垫子塌缩以使得能够沿着铰链线折叠以增强收缩的垫子的平整度,并且使得能够将垫子重复地折叠成限定的构造和小尺寸以便于存储。 阀装置允许流体连通到腔室中以限定充气垫,并进一步允许流体从腔室中流出,以便提供塌陷和放气的缓冲垫。 阀装置还包括当缓冲垫被放气时由充气介质启动的声音产生装置。
