Patent ID: 8852723

Claim:
An air cushion arrangement, comprising: a first air cushion assembly, comprising: a first sheet member, which is resilient and has a first surface on which a plurality of hollow tubes is raised and an opposite second surface in which an opening is formed for each of the hollow tubes, the first sheet member having a first circumference from which a first extension tab extends sideways; a second sheet member, which is resilient and has a third surface that opposes the second surface of the first sheet member, the second sheet member having a second circumference corresponding to and hermetically bonded to the first circumference of the first sheet member to form an internal space between the second surface and the third surface, a second extension tab extending sideways from the second circumference and corresponding to and bonded to the first extension tab to define an air passage therebetween, the air passage being in communication with the internal space and selectively sealed; a first lid, which is a single stiff plate positioned on the first surface of the first sheet member, holes being formed through the lid and corresponding to and receiving therethrough the hollow tubes of the first sheet member; a second air cushion assembly, comprising: a third sheet member, which is resilient and has a fifth surface on which a plurality of hollow tubes is raised and an opposite sixth surface in which an opening is formed for each of the hollow tubes, the third sheet member having a third circumference from which a third extension tab extends sideways; a fourth sheet member, which is resilient and has a seventh surface that opposes the sixth surface of the third sheet member, the fourth sheet member having a fourth circumference corresponding to and hermetically bonded to the third circumference of the third sheet member to form an internal space between the sixth surface and the seventh surface, a fourth extension tab extending sideways from the fourth circumference and corresponding to and bonded to the third extension tab to define an air passage therebetween, the air passage being in communication with the internal space and selectively sealed; a third lid, which is a single stiff plate positioned on the fifth surface of the third sheet member, holes being formed through the lid and corresponding to and receiving therethrough the hollow tubes of the third sheet member; and a flexible enclosure that encloses the first and second air cushion assemblies therein, wherein the enclosure comprises two flexible films that have circumferences hermetically bonded to each other; wherein the first and second air cushion assemblies are arranged to couple to each other with the hollow tubes of the first and second air cushion assemblies coupled with each other.
