DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0040] Referring to the drawings, FIG. 1 shows a breathing half mask 1 according to the present invention in its use state during use by a user 100. The breathing half mask 1 and the user 100 are shown in a lateral sectional view. The breathing half mask 1 according to the present invention has especially three mask sections 10. The mask sections 10 are especially a nose section 11, a chin section 12 as well as a mouth section 13. Connection sections 20 of the individual mask sections 10 make it possible to connect two respective adjacent mask sections 10, especially the nose section 11 and the mouth section 13, as well as the mouth section 13 and the chin section 12. The connection sections 20 represent at the same time the folding areas 40, at which the breathing half mask 1 according to the present invention can be brought by a folding process from a storage state into a use state. Further, especially a breathing space 43, which is located essentially between a mouth and a nose of the user 100 and the mouth section 13, is defined by the mouth section 13. The nose section 11 further has a nose sealing line 41 and, analogously to the chin section 12, a chin sealing line 42, which are intended for being in contact with a corresponding face section of the user 100 and which ensure sealing of the breathing half mask 1 according to the present invention against the face of the user 100. The different shadings of the mask sections 10 on the shown breathing half mask 1 according to the present invention already suggest that provisions are made as an essential feature of the present invention for the different mask sections 10 of the breathing half mask 1 according to the present invention to be able to have different filter materials 30 (not shown). It can be made possible in this manner that the different mask sections 10 can also provide different properties, made possible and influenced by the respective filter material 30. For example, the nose section 11 as well as the chin section 12, which may also have, as shown, the same filter material 30, have a filter material 30, which provides for an especially high wearing comfort for a user 100 of a breathing half mask 1 according to the present invention. The filter material 30 of the mouth section 13 may, by contrast, be selected, for example, with respect to an especially low breathing resistance, and the mouth section 13 preferably also provides at least essentially the filter functionality of the breathing half mask 1 according to the present invention. On the whole, both a required filter functionality and a high wearing comfort can be provided by a breathing half mask 1 according to the present invention.
[0041] FIG. 2 shows a breathing half mask 1 according to the present invention in a sectional view, wherein especially the different filter materials 30 of the individual mask sections 10 of the breathing half mask 1 according to the present invention are shown. The filter materials 30 of the nose section 11 as well as of the chin section 12 are, in turn, selected as the same material here. It is clearly seen, furthermore, that the individual filter materials 30 have a layer structure 31, where the layer structures 31 differ, for example, in the number of the material layers 32 as well in the use of the types of material layers 32. In particular, the mouth section 13 may have, for example, a layer structure 31 that is configured such that the entire filter material 30 of the mouth section 13 is thicker than the filter materials 30 of the nose section 11 as well as of the chin section 12. Further, it is seen that the connection sections 20 between the nose section 11 and the mouth section 13 as well as between the mouth section 13 and the chin section 12 are reliably connected to one another by a welded connection 21. Such welded connections 21 represent especially reliable connections between the individual mask sections 10, for example, especially when textile filter materials 30 are used as the filter material 30. Further, filter materials 30 having different densities may also be used for the individual mask sections 10, in which case, for example, the filter materials 30 of the nose section 11 as well as of the chin section 12 have a weight per unit area between about 20 g/m.sup.2 and about 100 g/m.sup.2 and the filter material 30 of the mouth section 13 has a weight per unit area between about 40 g/m.sup.2 and about 500 g/m.sup.2. It can also be made possible in this manner, in particular, that the breathing resistances are different between the individual mask sections 10, the mouth section 13 preferably having the lowest breathing resistance of all mask sections 10 due to the filter material 30 used. An especially unhindered breathing of a user 100 (not shown) can be made possible in this manner by the breathing half mask 1 according to the present invention. To provide the filter property, the filter materials 30, especially the filter material 30 of the mouth section 13, may be configured as a mechanical and/or electrostatic and/or triboelectric filter material 30.
[0042] Further, FIG. 3 shows a breathing half mask 1 according to the present invention during the manufacture of the breathing half mask 1 according to the present invention. The individual mask sections 10, especially a nose section 11, a mouth section 13 as well as a chin section 12, are arranged next to one another. Mutually adjacent mask sections 10 are already connected to one another at least partially by a welded connection 21 at their respective connection sections 20. The other sections of the connection sections 20 can also be connected, especially welded, to one another due to an easy folding up, made possible especially by the connection sections 20 being configured as a folding area 40. The different shadings of the individual mask sections 10 already suggest again that at least the mouth section 13 has a different filter material 30 than the nose section 11 as well as the chin section 12. A respective nose sealing line 41 and a chin sealing line 42 are already shown at the ends of the nose section 11 as well as of the chin section 12, which ends face away from the mouth section 13.
[0043] FIG. 4 is a view of the breathing half mask 1 in a storage state wherein the chin section 12 is folded relative to the mouth section 13 and then the nose section 11 is folded relative to chin section 12 and the mouth section 13 such that the chin section 12 is located between the mouth section 13 and the nose section 11. The use state of the breathing half mask 1 is formed by moving the nose section 11 relative to the mouth section 13 and the chin section 12 and then moving the chin section 12 relative to the mouth section 13.
[0044] FIG. 5 is a view of the breathing half mask 1 in a folded state wherein the nose section 11 is folded relative to the mouth section 13 and then the chin section 12 is folded relative to nose section 11 and the mouth section 13 such that the nose section 11 is located between the mouth section 13 and the chin section 12. The use state of the breathing half mask 1 is formed by moving the chin section 12 relative to the mouth section 13 and the nose section 11 and then moving the nose section 11 relative to the mouth section 13.
[0045] While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
