Inflatable pad and methods for using the same
The inflatable pad includes an inflatable frame having a length and width that defines a pad area suitable for supporting a person lying thereon. A plurality of internal support members are configured to support the weight of a person lying thereon and elevate the person above the ground. The inflatable pad includes non-supporting regions that require less fill volume than regions that support primary support regions such as the hips and shoulder.
1. An inflatable pad comprising:
a frame comprising: a first sheet of material and a second sheet of material joined at a plurality of bond lines, wherein the bond lines are elongated, wherein at least one end of each of the bond lines increases in width;
a plurality of fluidly coupled cells defined between at least two bond lines of the plurality of bond lines, wherein the plurality of fluidly coupled cells comprise a first width and a second width; and
a first valve coupled to the frame and in fluid communication with the plurality of fluidly coupled cells.
2. The inflatable pad of claim 1 , wherein the first width and the second width are the same.
3. The inflatable pad of claim 1 , wherein the first width and the second width are the different.
4. The inflatable pad of claim 1 , wherein the elongated bond lines are longer than they are wider.
5. The inflatable pad of claim 1 , further comprising a primary region and a secondary region, wherein the primary region comprises a greater number of fluidly coupled cells than the secondary region.
6. The inflatable pad of claim 5 , wherein the primary region is configured to support at least a head of a user.
7. The inflatable pad of claim 1 , wherein an average vertical thickness of the plurality of fluidly coupled cells is in a range from 2.5 cm to 10 cm.
8. An inflatable pad comprising:
a pad area;
a first valve coupled to a frame and in fluid communication with the plurality of fluidly coupled cells;
the frame comprising a first sheet of fabric material and a second sheet of fabric material joined at a plurality of bond lines with at least one bond line around the entire periphery of the first sheet of fabric material and the second sheet of fabric material, wherein at least one end of each of the plurality of bond lines increases in width;
wherein the plurality of bond lines comprise non-supporting regions wherein the non-supporting regions cover at least 25 cm 2 of the pad area.
9. The inflatable pad of claim 8 , wherein a portion of the plurality of bond lines are non-perpendicular to the periphery of the frame.
10. The inflatable pad of claim 8 , wherein the bond lines are elongated and the bond lines are longer than they are wider.
11. The inflatable pad of claim 8 , wherein the plurality of fluidly coupled cells comprise a first width and a second width wherein the first width is the same as the second width.
12. The inflatable pad of claim 8 , wherein the plurality of fluidly coupled cells comprise a first width and a second width wherein the first width is different from the second width.
13. The inflatable pad of claim 8 , wherein the frame has a maximum width in a range from 40 cm to 60 cm and a maximum length in a range from 150 cm to 200 cm with a fill volume/pad area in a range from about 0.4-4.0 ml/cm 2 .
14. The inflatable pad of claim 8 , wherein an average vertical thickness of the plurality of fluidly coupled cells is in a range from 2.5 cm to 10 cm.
15. An inflatable sleeping pad comprising:
a frame configured to hold air and configured to support a person sleeping thereon, the frame comprising:
a first sheet of material and a second sheet of material joined at their periphery by an outer bond line;
a plurality of bond lines within the periphery of the outer bond line wherein at least one end of each of the plurality of bond lines within the periphery increases in width;
a plurality of fluidly coupled cells defined between at least two bond lines of the plurality of bond lines; and
a first valve coupled to the frame and in fluid communication with the plurality of fluidly coupled cells.
16. The inflatable sleeping pad of claim 15 , wherein a portion of the plurality of bond lines are in communication with the outer bond line.
17. The inflatable sleeping pad of claim 15 , wherein a portion of the plurality of bond lines are separate from and not in communication with the outer bond line.
18. The inflatable pad of claim 15 , wherein the plurality of bond lines are elongated and flare toward a second end of the plurality of bond lines.
19. The inflatable pad of claim 15 , wherein the plurality of fluidly coupled cells comprise a first width and a second width wherein the first width is the same as the second width.
20. The inflatable pad of claim 15 , wherein the plurality of fluidly coupled cells comprise a first width and a second width wherein the first width is different from the second width.
