DETAILED DESCRIPTION OF THE INVENTION

[0094] Basically, in the figures, the same parts are provided with the same reference numerals.

[0095] The covering envelope 1.1, 1.2, 1.3 according to FIG. 1a to 1c includes a multi-layered construction. The covering envelope 1.1, 1.2, 1.3 forms a body side 3 that faces the body of a person 4 which is to be kept warm, as well as an outer side 2 that is arranged opposed to the body side 3 and in particular faces the environment.

[0096] The covering envelope 1.1, 1.2, 1.3 in each case has a transfer layer 6.1, 6.2, 6.3, which faces the body side 3, a blocking layer 11.1, 11.2. 11.3, which faces the outer side 2, as well as a storage layer 5.1, 5.2, 5.3 for condensation water, arranged between the transfer layer 6.1, 6.2. 6.3 and the blocking layer 11.1, 11.2, 11.3.

[0097] According to the embodiment according to FIG. 1a, a spacer layer 7.1 is arranged between the transfer layer 6.1 and the storage layer 5.1 and this spacer layer distances the transfer layer 6.1 from the storage layer 5.1. The spacer layer 7.1 includes a thermally insulating material and simultaneously serves as an insulation layer for the thermal insulation of the body side 3.

[0098] A barrier layer 9.1, which is permeable to water vapour in the direction of the storage layer 5.1 and is water-tight in the direction of the body side 3, is arranged between the spacer layer 7.1 and the storage layer 5.1.

[0099] According to the embodiment according to FIG. 1b, an insulation layer 8.2 for the thermal insulation of the body side 3 is arranged between the storage layer 5.2 or the blocking layer 11.2, and the outer side 2 of the covering envelope 1.2.

[0100] The blocking layer 11.2, which is watertight in the direction of the outer side 2 and therefore prevents a penetration of moisture into the insulation layer 8.2, is arranged between the insulation layer 8.2 and the storage layer 5.2.

[0101] According to the embodiment according to FIG. 1c, a spacer layer 7.3, which distances the transfer layer 6.3 from the storage layer 5.3, is arranged between the transfer layer 6.3 and the storage layer 5.3. The spacer layer 7.3 includes a thermally insulating material and simultaneously serves as an insulation layer for the thermal insulation of the body side 3.

[0102] A barrier layer 9.3, which is permeable to water vapour in the direction of the storage layer 5.3 and is water-tight in the direction of the body side 3, is arranged between the spacer layer 7.3 and the storage layer 5.3.

[0103] An insulation layer 8.3 for the thermal insulation of the body side 3 is furthermore arranged between the storage layer 5.3 or the barrier layer 11.3, and the outer side 2 of the covering envelope 1.3.

[0104] The blocking layer 11.3, which is watertight in the direction of the outer side 2 and therefore prevents a penetration of moisture into the second insulation layer 8.3, is arranged between the second insulation layer 8.3 and the storage layer 5.3.

[0105] FIG. 2 shows a self-supporting, shape-stable sleeping unit 50. The sleeping unit 50 has an envelope body that forms a body receiving compartment 51 for receiving a person 4. The envelope body is designed in a two-part manner and includes an outer envelope 56 with an outwardly facing outer side, as well as an inner envelope 52, which is introduced into the outer envelope 56 and is with an inner side facing the body receiving compartment 51.

[0106] The inner envelope 52 is separable from the outer envelope 56 and can be removed from this and be reinserted into this.

[0107] FIGS. 3a, 3b, 4a, 4b, 5 and 6 show a covering envelope 80, which is designed as a sleeping bag. The covering envelope 80 is present as an envelope body with a body receiving compartment.

[0108] The envelope body is likewise designed in a two-part manner and includes an outer envelope 86 and an inner envelope 82. The outer envelope 86 and the inner envelope 82 in each case form a head opening 90. The outer envelope 86 and the inner envelope 82 moreover each include a zip closure 91, 92, which is arranged laterally in the longitudinal direction, for opening the outer envelope 86 and the inner envelope 82 respectively. The zip closure 91 in the outer envelope 86 on the one hand serves for introducing the inner envelope 82 into the outer envelope 86 and on the other hand as an access opening. The zip closure 92 in the inner envelope 86 serves as an access opening.

[0109] According to the two embodiments which are mentioned above, the inner envelope 52, 82 is designed in a multi-layered manner. The inner envelope 52, 82 includes a transfer layer 53, 83, which forms the inner side, thus faces the body receiving compartment 51, 81. The transfer layer 53, 83 is permeable to water vapour but is water-tight. The transfer layer 53, 83 is an outer layer.

[0110] The inner envelope 52, 82 moreover includes a second outer layer 55, 85 in the embodiment of a blocking layer, which faces the outer envelope 56, 86. The second outer layer 55, 85 is water-tight and water-vapour-tight. An intermediate layer 54, 84 is arranged between the two outer layers 53, 83; 55, 85. The intermediate layer 54, 84 is a storage layer, which stores the moisture that is led away through the transfer layer 52, 83 from the body receiving compartment 51, 81 into the intermediate layer 54, 84. The moisture in the intermediate layer 54, 84 can no longer penetrate outwards into the outer envelope 56, 86, since the second outer layer 55, 85 is water-tight and water-vapour-tight.

[0111] The outer envelope 56, 86 is likewise designed in a multi-layered manner and includes a first outer-lying layer 57, 87, which faces the inner envelope 52, 82 and forms the inner side. The outer envelope 56, 86 moreover has a second outer-lying layer 59, 89, which forms the outer side, thus faces outwards. The first and the second outer-lying layer 57, 87; 59, 89 are water-tight and water-vapour-tight. An intermediate layer 58, 88 is arranged between the two layers 57, 59; 87, 89. The intermediate layer 58, 88 is an insulation layer for the thermal insulation of the body receiving compartment 51, 81.

[0112] Moisture that gets from the body receiving compartment 51, 81 into the intermediate layer 54, 84 of the inner envelope 52, 82, remains captured in this, by which means the body receiving compartment 51, 81 can be kept dry. Only by way of removing the inner envelope 52, 82 out of the outer envelope 56, 86 can this be dried, and moisture be led away out of the intermediate layer 54, 84.

[0113] FIG. 7 shows a covering envelope 13 according to the invention, in the form of a cover with a layered construction 1.3 according to FIG. 1c. The covering envelope 13 includes a reclosable exposure opening 12 for laying open, which is to say exposing, the storage layer 5.3. The exposure opening 12 is closable by way of a zip closure.

[0114] The storage layers 5.1, 5.2, 5.3, 54, 84 according to FIGS. 1a-1c, 2 and 5 can moreover include a material that creates a space (distance) described above and that creates or forms a cavity for receiving the condensing moisture.
