Claims30
An inflatable product comprising:
- a first wall;
- a second wall;
- an inflatable air chamber defined by the first wall and the second wall;
- and
- a plurality of tensioning structures located in the air chamber and coupled to the first wall and the second wall, each tensioning structure including:
- at least one attachment sheet having an outer perimeter;
- and
- a porous sheet coupled to the at least one attachment sheet, the porous sheet having an outer perimeter that substantially overlaps the outer perimeter of the at least one attachment sheet, the porous sheet including a plurality of enclosed pores located entirely within the outer perimeter of the at least one attachment sheet and a plurality of frame members that intersect to define the plurality of enclosed pores.

An inflatable product comprising:
- a first wall;
- a second wall;
- an inflatable air chamber defined by the first wall and the second wall;
- and
- a plurality of tensioning structures located in the air chamber, each tensioning structure being coupled to the first wall along a first seam that extends along a first line and to the second wall along a second seam that extends along a second line, each tensioning structure including a porous sheet with a plurality of pores, wherein any line parallel to the first line intersects the plurality of pores in the porous sheet and the first line is parallel to the second line.

A method of manufacturing an inflatable product having an air chamber defined by a plurality of walls, the method comprising:
- providing a porous sheet of a first material including a plurality of frame members that cooperate to define a plurality of pores, at least a portion of the first material surrounding the plurality of pores in the porous sheet;
- placing the porous sheet between a second sheet of a second material and a third sheet of a third material, the second material and the third material covering the portion of the first material that surrounds the plurality of pores in the porous sheet;
- attaching the second sheet to the third sheet;
- placing the porous sheet in the air chamber of the inflatable product;
- and
- attaching the porous sheet to a first wall of the plurality of walls along a first seam that extends along a first line and attaching the porous sheet to a second wall of the plurality of walls along a second seam that extends along a second line, the plurality of frame members being oriented transverse to the first line.
