Abstract
The invention provides an inflatable sleeping bag having a wall structure defining a sleeping envelope and including outer and inner skins spaced from one another in use. A shoulder cover is provided which is held in place by engaging an inflated pillow. A double zipper holds the upper and lower portions of the bag together in such a way that internal air pressure prevents the leakage of air into or out of the occupant's area of the bag. A plurality of strap structures are attached between the skins to hold the skins generally in parallel one with the other after inflation, and an insulating material is contained between the skins and located against movement by the strap structures. Inflation means is associated with the wall structure for inflating the bag and including exhaust means operable to deflate the bag. The strap structures can be used in any similar inflated structure.
