Inflatable raft having continuous gas cell formed from single sheet.

摘要

A flexible, rectangular, impermeable sheet of rubberized cloth is formed into an elongated, continuous, linear tube, which is then joined end to end to produce a continuous circular gas cell (14) for a raft. The cell is bent at several corners into a polygonal configuration, and angulation members (26) are attached to the corners to retain the bends and preserve the desired cell shape upon inflation. A bottom sheet (42) is attached to the polygonal cell (14) to complete the raft.
