Multilayer safety blanket and system

A system for covering a user, the system comprising:

• a user base platform adapted to have the user positioned thereon;
• at least one mounting element, disposed about said user base platform;
• a blanket, including:
• a first layer formed of a first stretch of fabric, said first stretch of fabric having, when fully spread out, a first length (l1) and a first width (w1);
• a second layer formed of a second stretch of fabric, said second stretch of fabric having, when fully spread out, a second length (l2) and a second width (w2), said second length being greater than said first length and said second width being greater than said first width,
• wherein said first and second layers are attached to one another so as to be juxtaposed to one another around a perimeter of said blanket, and along at least one internal elongate stretch of said blanket so as to define at least two pockets formed between said first and second layers,
• wherein, in a resting disposition defined by said blanket being spread out on a flat surface, excess length and width of said second layer is arranged in at least one arrangement selected from the group consisting of folds, creases, and pleats;
• and
• an attachment mechanism adapted to attach said blanket to said at least one mounting element,
• said system adapted to have an operative, hanging mode, in which said blanket is attached to said at least one mounting element and hangs over said user base platform;
• wherein, in said operative hanging mode, a portion of said second layer forming one of said at least two pockets has a greater width and a greater length than a corresponding portion of said first layer forming said one of said at least two pockets,
• wherein, in said operative, hanging mode, said at least two pockets each have a respective depth (D) between said first layer and said second layer, said depth (D) being within the range of 10 cm to 30 cm,
• wherein, in said operative, hanging mode, an air gap is formed between said at least two pockets, and
• wherein, in said operative hanging mode, said second layer of each of said at least two pockets defines an apex at said depth D, and wherein a width of said air gap (wg), defined between apexes of said at least two pockets surrounding said air gap, is within the range of 20 cm to 40 cm.
