| 摘要 |
The invention is directed to hybrid inflatable bodies comprising opposing flexible panel portions sealed at a common perimeter thereof, and having valve means for selectively allowing fluid ingress and egress between the environment and a chamber substantially defined by inner surfaces of the flexible panels. Such inflatable bodies further comprise a core that is selectively bonded to the inner surfaces o the panel portions, characterized in that the bodies have a reduced bonded area to non-bonded area ratios and/or have elongate extending air channels extending through the inflatable body. Additionally, elongate extending air channels are characterized as core-free channels bounded, at least in part, by opposing panels of the inflatable body (i.e., nonbonded areas) that extend in a transverse direction (i.e., normal to anticipated user-initiated compressive forces). In many preferred embodiments, the core is comprised of an open cell foam, such as an expanded or foamed polyurethane. |
