• the principle of the invention is therefore based on the implementation of non-removable cooling portions on cover and / or protection devices such as clothing or covers, comprising at least one flexible layer containing a cooling solution interposed between a breathable inner layer and outer thermal insulation layer.
• Figure 1 is a partial view of the trunk of a cook wearing under his jacket (shown for clarity in dashed lines in Figure 1) a first example of cover device and / or protection according to the invention, set it works in the form of a pneumothoracic belt 10, to cool off when it is activated, for example, near a furnace in summer.

• it is equipped with removable closure means of a known type, such as for example a velvet band and velcro type hooks 11 (registered trademark) in this first embodiment of the invention. It is also possible to provide snaps, pins, or any other similar means, in variants of this embodiment.
• a cutaneous refresh portion 12 is sewn over the entire length of the belt 10.
• a fourth layer 24 stored at room temperature.
• This layer 24 eliminates, or at least mitigates, the unpleasant, and possibly painful, effect of contact with a cold surface and / or locally frosted with the skin, when applying the belt against the bust. It also has holes or meshes distributed over its surface, so as to form a "breathable" surface.
• the layer 24 is removably attached to the layer 21 by self-gripping means, for example hook-and-loop fasteners provided on one of its faces that are secured to corresponding tie-loops provided for this purpose on the surface of the layer. 21. It can be easily removed from the portion 12, when the cooling effect has ceased, before replacing the belt in the freezer.
• the inner face of the portion 12 is formed of a first breathable layer 21 perforated mesh having passages to allow evacuate perspiration and transpiration.
• This first layer 21 is for example obtained in a stitch machine washable, composed of 60% polyester and 40% cotton and surface treated to prevent discoloration resulting from the action of sweat. It is also fleece for comfort, and preferably meets the criterion of class Fl (NF standard) in terms of smoke toxicity.
• the thermal resistance of the layer 21 has been provided to a value sufficient to prevent the proximity of the second storage layer and cold restitution 22 with the skin does not create an unpleasant sensation through this layer 21.
• the second layer 22 is formed of an alignment of refrigerant flexible bags 221, for example of the mark Firstlce (registered trademark), slid inside compartments 222 of a sleeve 223 of textile material. These compartments 222, substantially contiguous in pairs, are closed by a seam so as to permanently retain the bags 221.

• Each of the sachets 221 contains a gelatinous mixture composed of a substantially liquid solution consisting of 85% by weight of water and 15% of humectant, such as propylene glycol, ethylene glycol, glycerol, dimethyl sulfoxide, dimethyl formamide, or a humectant from their combination, and a plurality of hydrophobic absorbers distributed in the solution.
• humectant such as propylene glycol, ethylene glycol, glycerol, dimethyl sulfoxide, dimethyl formamide, or a humectant from their combination
• This humectant decreases the mobility of the water outside the hydrophilic absorbers, each volume of water then freezes forming a dispersed flake. An overall consequence is therefore that below 0 ° C, and up to -18 ° C at least, the humectant prevents water from forming a compact rigid mass connecting the absorbers.
• the third layer 23 makes it possible to isolate the body from the outside hot air and to prevent an excessive loss of the cold stored by the cold storage layer 22. It is advantageously made in a single room to avoid the phenomenon of thermal bridge ".
• the layer 23 consists of an alternation of heat radiation reflective layers 231, 233, or 235, aluminized, with air retention layers 232 or 234 formed of wadding, in order to fight properly. against heat transport by radiation and convection. Ashing bumps, obtained for example by punching, are provided on the face of the aluminized layers facing the layer 22, so as to facilitate the attachment of the air retention layers.
• the layer 23 is covered with an outer layer of flame retardant fabric 236 treated with teflon, in order to limit moisture retention.
