Abstract
A sleeping bag constructed such that its outer circumference is greater than its inner circumference includes additional integrated protuberances, or space fillers, that are added to the interior lining of the sleeping bag to fill-in around the sleeper's body. Making the circumference of the outside of the bag greater than the inside maintains the thickness of the insulation in selected areas. To maintain insulation thickness at other locations around the sleeper's body, the insulation-containing space fillers are incorporated into the interior of the bag and expand under the influence of the insulation to fill-in around the sleeper for reducing the internal volume of the bag. This construction can be carried the length of the sleeping bag.
Claims22
A differentially cut sleeping bag assembly, comprising:
- first and second opposed halves each having an inner shell and an outer shell and the opposed halves defining a sleeping bag compartment therebetween;
- the first and second opposed halves converging towards a first apex;
- the inner and outer shells of the first opposed halves joined together at the first apex;
- the inner and outer shells of the second opposed halves joined together at the first apex;
- and
- a first space filler extending along at least a portion of the first apex and into the sleeping compartment for filling voids surrounding a user's body.
A differentially cut sleeping bag assembly, comprising:
- an inner shell having an inner circumference to define a sleeping bag compartment;
- an outer shell having an outer circumference being greater than the inner circumference, the inner and outer shells converging towards and joined together at an apex;
- and
- a space filler extending along at least a portion of the apex and into the sleeping bag compartment for filling voids surrounding a user's body.
