Abstract
A self-inflating stowable bed. The bed includes one or more self-inflating chambers, with each of the self-inflating chambers having one or more polyurethane foam sections therein, with the chamber defined between a first air impervious layer and a second air impervious layer. The self-inflating bed may be evacuated by a household or shop vacuum, and then sealed, rolled or folded, and easily stored or shipped. The polyurethane foam sections may be provided with different members having different indentation force deflection specifications suitable for bed portions and edge of bed portions.
Claims20
A self-inflating bed, comprising:
- one or more self-inflating chambers having a length LC, each of said one or more self-inflating chambers defined between a first air impervious layer and a second air impervious layer, said first air impervious layer and said second air impervious layer each comprising a thermoplastic material having an internal side and an external side, and a thickness T of between one (1) mil (0.001 inches) and twelve (12) mils (0.012 inches), wherein each of the one or more self-inflating chambers further comprises a vacuum port valve;
- a first bonding layer adhered to said internal side of said first air impervious layer, and a second bonding layer adhered to said internal side of said second air impervious layer, each of said first bonding layer and said second bonding layer comprising an extruded bonding composition having a finished thickness 8 of between one-half (½) mil (0.0005 inches) and six (6) mils (0.006 inches);
- one or more polyurethane foam sections along the length LC, wherein said one or more polyurethane foam sections are affixed to said first bonding layer and to said second bonding layer, and wherein said one or more polyurethane foam sections comprises an interior portion having a twenty five percent (25%) indentation force-deflection factor, as measured by ASTM standard D3574, and said interior portion further comprising a perimeter;
- an edge portion, the edge portion extending outward from said perimeter, wherein at least some of said edge portion comprises a polyurethane foam layer having a twenty five percent (25%) indentation force-deflection factor as measured by ASTM standard D3574,
- wherein a ratio of the edge portion indention force deflection factor divided by the interior portion force deflection factor is in a range of from one point zero (1.0) to eight point five (8.5);
- and
- wherein the edge portion and the one or more polyurethane foam sections are both within at least one of the self-inflating chambers.

- wherein the one or more polyurethane foam sections comprising the interior portion have a twenty five percent (25%) indentation force-deflection factor, as measured by ASTM standard D3574;
- wherein the edge portion has a twenty five percent (25%) indentation force-deflection factor as measured by ASTM standard D3574, and
- wherein a ratio of the edge portion indention force deflection factor divided by the interior portion force deflection factor is in a range of from one point zero (1.0) to eight point five (8.5), and
- wherein the edge portion and the one or more polyurethane foam sections are both within at least one of the self-inflating chambers.
