Abstract
Abstract A self inflatable air mattress provided with a core of flexible and resilient cellular material of the open cell type, and an air tight flexible jacket enclosing the core. A tube communicating with the interior of the jacket allows flow of air into and from the core cells; and a closure for the tube maintains the cells filled to form a resilient air cushion. A cover attached to the jacket provides a sleeping bag. Because of the nature of the material, the entire construction can be readily wound into a compact roll.

Claim 1
Independent Claim
187 words
A sleeping bag comprising a self inflatable air mattress having a core of flexible and resilient cellular material of the open cell type allowing free passage of air therethrough, a substantially air tight flexible jacket enclosing said core, a tube communicating with the interior of the jacket from exteriorally thereof for flow of air into and from the cells of said core, an openable and reclosable closure for said tube which in its closed condition with the cells filled with air prevents escape of air from said cells and maintains them filled with air to provide a resilient air cushion, and which when open and the mattress placed under compression allows escape of air from said cells and flattening of said mattress, and a cover overlying the top of said jacket and fixedly attached thereto adjacent one end and opposite sides thereof, said cover having adjacent portions each greater than one-half the width of the mattress so as to be capable of overlapping, the adjacent portions being provided with an openable and reclosable closure to enable opening and closing of the cover while attached to the jacket.

Claim 5
Dependent Claim
152 words
A sleeping bag comprising a self inflatable air mattress having a core of flexible and resilient cellular material of the open cell type allowing free passage of air therethrough, a substantially air tight flexible jacket enclosing said core, a tube communicating with the interior of the jacket from exteriorally thereof for flow of air into and from the cells of said core, a manually removable cap for said tube whereby air can fill the core cells when the cap is removed and upon closing of said cap maintain the cells filled to provide a resilient air cushion, and a cover overlying said jacket and attached thereto adjacent one end and opposite sides thereof, said cover having adjacent portions provided with an openable and reclosable closure to enable opening and closing of the cover, and said bag having a heat reflective barrier sheet positioned between the bottom of said core and such jacket.
Claim 6
Dependent Claim
152 words
A sleeping bag comprising a self inflatable air mattress having a core of flexible and resilient cellular material of the open cell type allowing free passage of air therethrough, a substantially air tight flexible jacket enclosing said core, a tube communicating with the interior of the jacket from exteriorally thereof for flow of air into and from the cells of said core, a manually removable cap for said tube whereby air can fill the core cells when the cap is removed and upon closing of said cap maintain the cells filled to provide a resilient air cushion, and a cover overlying said jacket and attached thereto adjacent one end and opposite sides thereof, said cover having adjacent portions provided with an openable and reclosable closure to enable opening and closing of the cover, and said bag having a heat reflective barrier sheet positioned between the bottom of said core and such jacket.
Claim 7
Dependent Claim
154 words
A self inflatable air mattress comprising a core of flexible and resilient cellular material of the open cell type allowing free passage of air therethrough, a substantially air tight flexible jacket enclosing said core, a tube communicating with the interior of said jacket from exteriorally thereof for flow of air into and from the cells of said core, and an openable and reclosable closure for said tube which in its closed condition with the cells filled with air prevents escape of air from said cells and maintains them filled with air to provide a resilient air cushion, and which when open and the mattress placed under compression allows escape of air from said cells and flattening of said mattress, said mattress having a mandrel about which said mattress can be wound into a roll to compress the same and thus expel air from said tube and flatten the mattress when said closure is open.
