Definitions

  • the invention relates to a respiratory mask for filtering the respiratory air of a wearer or a person.
  • the respirator is used in particular in the field of occupational safety. Other applications are possible.
  • the invention is based on the object to provide a respirator, which offers the wearer of the respirator a particularly high level of protection. Furthermore, the respirator should have a very good wearing comfort.
  • the essence of the invention lies in the fact that the respirator mask has a sealing lip and facial hump, whose facial surface head surfaces are not covered by the sealing lip.
  • the sealing lip has at least one corresponding recess in the facial humps. There may be a continuous recess in the facial bumps that extends substantially across the nose cup. Alternatively, each facial system cusp is assigned its own recess. There are then two separate recesses available.
  • the facial cusps are attachable to the face of the wearer via their face-cap head surfaces when the respirator is worn. They then preferably rest on the nostrils and / or on carriage areas adjacent the nose of the wearer.
  • the respirator is so special slip-proof secured to the carrier and in particular has a very good grip on the carrier even when the wearer moves.
  • the respirator mask thus has a particularly high protective effect. It protects the wearer, for example, against contaminants in dangerous or harmful environments.
  • the mask body is designed as a dimensionally stable molded body.
  • the sealing lip is preferably formed in one piece. It is advantageous if the sealing lip is designed as a separate part, which is tightly connected to the end edge region. An integral design of the sealing lip with the mask body is alternatively possible. Conveniently, the sealing lip is formed of a plastic foam.
  • the embodiment according to claim 2 leads to an extremely safe respiratory mask, since the sealing lip seals so well in the area of the facial cusp. It is advantageous if in each case the face-bump outer side opposite facial cusp-inside of the sealing lip uncovered or remains free. Preferably, the side surfaces of the facial system bumps oriented transversely to the circumferential direction of the mask body also remain substantially free of the sealing lip or uncovered.
  • the respirator fits particularly well to the face of the wearer, which allows a very high protection of the wearer of the respirator.
  • the facial abutment portion in the area of the facial abutment has an average width B H between 1 mm and 5 mm, more preferably between 2 mm and 4 mm.
  • the connecting portion of the sealing lip in the final edge region is firmly connected to the mask body.
  • the sealing lip is welded or glued to the mask body. It is advantageous if the sealing lip is firmly connected to the mask body along the entire end edge region.
  • the embodiment according to claim 9 allows a particularly safe wearing the respirator.
  • the respirator of claim 10 is particularly well fixed to the face of the wearer.
  • the facial humps prevent the respiratory mask from slipping sideways. This results in an extremely safe respirator and tight connection with the wearer.
  • the embodiment of claim 12 allows breathing directly through the mask body.
  • the filter material filters the respiratory air.
  • the air-permeable Filter material is preferably a nonwoven material. As a filter material is also a composite in question.
  • the mask body can also be formed from an air-impermeable material, if at least one exhalation valve and inhalation valve are arranged on the mask body.
  • the respirator according to claim 13 allows a particularly simple exhalation.
  • the respirator according to claim 14 has a particularly large filter surface and protects the wearer particularly well against contaminants.
  • the at least one inhalation valve allows extremely simple inhalation.
  • the embodiment according to claim 15 allows a particularly tight fit of the respirator on the carrier.
  • the fixing means is for example a string, a band, a hood or the like. It is preferably formed of an elastic material such as a rubber.
  • One in the Fig. 1 to 3 illustrated respirator mask comprises a cup-shaped, three-dimensional mask body 1 and on the mask body 1 edge-mounted, circumferential sealing lip 2 for engagement with the face of the wearer.
  • the mask body 1 has a longitudinal central axis 3 which passes through the center of the respirator.
  • the longitudinal central axis 3 lies in a plane of symmetry E which divides the respiratory mask into two equal halves.
  • the respirator is thus symmetrical.
  • the mask body 1 has a free end edge region 4, which goes around the longitudinal central axis 3 and is closed in a circumferential manner.
  • the end edge region 4 lies substantially in a plane that intersects the longitudinal center axis 3 perpendicularly. It runs approximately annularly around the longitudinal central axis 3.
  • the mask body 1 has a side wall 5 and a front panel 6 adjoining the side wall 5.
  • the front panel 6 is arranged at a distance from the end edge region 4. It lies substantially in a plane that is parallel to the plane enclosing the end edge region 4.
  • the side wall 5 and the front panel 6 together define a mask body interior space 7.
  • the side wall 5 limits the side of the mask body interior space 7, while the front panel 6, the mask body interior 7 bounded forward.
  • the side wall 5 runs slightly together from the end edge region 4 in the direction of the front field 6.
  • the mask body 1 has a lower chin area 8 in the side wall 5. Opposite to the lower chin area 8, the mask body 1 has an upper nose receptacle 9 in the side wall 5, which is dimensionally stable.
  • the nose receptacle 9 is adapted in shape and size to the contour of the nose of the wearer.
  • the plane of symmetry E passes through the chin region 8 and the nose receptacle 9.
  • the nasal receptacle 9 is bounded at the top by a nasal bridge field 10, to which laterally two opposing Nasenhofflfelder 11 of the nose receptacle 9 connect.
  • the nose receptacle 9 extends between the end edge region 4 and the front field 6.
  • the mask body 1 is curved inward in the region of the two nostril fields 11 in the direction of the longitudinal central axis 3. In the area of the nose receptacle 10, the end edge region 4 extends approximately angularly.
  • the mask body 1 has two face contact bumps 12 in the nose receptacle 9, which are identical.
  • a facial system hump 12 at the end edge region 4 at.
  • the facial system bumps 12 project in the direction of the longitudinal center axis 3 opposite the end edge region 4 to the rear. They thus extend from the end edge region 4 opposite to the side wall 5.
  • Each facial bump 12 has a closed facial head surface 13 which is curved or flat.
  • each facial cusp 12 has a facial cusp outside 14 and an opposite facial cusp inside 15.
  • the facial cusp outer sides 14 each face an adjacent portion of the end edge region 4.
  • the facial bump outer side 14 and the facial bump inner side 15 of a facial hump 12 are connected to each other via opposing facial hump side regions 16.
  • the face plant bumps 12 are three-dimensional.
  • the sealing lip 2 has an outer connecting portion 17 and an adjoining this on the inside face-conditioning portion 18th
  • the connecting portion 17 is fixedly connected to the mask body 1 along the rear edge portion 4. It is essentially immovable relative to the mask body 1.
  • the connecting portion 17 is circumferentially closed.
  • the facial abutment portion 18 is internally connected to the connecting portion 17 and is flexible and free. It is movable relative to the mask body 1, in particular pivotable.
  • the facial abutment portion 18 protrudes into the mask body interior 7 and extends in the direction of the longitudinal center axis 3.
  • the facial abutment portion 18 extends largely obliquely to the longitudinal central axis 3, when the respirator is not worn. He is closed all around.
  • the width of the sealing lip 2 is not constant ( Fig. 2 ).
  • the sealing lip 2 has different widths.
  • the width of the sealing lip 2 is understood to be the dimension of the sealing lip 2, which extends perpendicular to its circumferential direction or in the direction of the longitudinal central axis 3.
  • the width of the sealing lip 2 initially increases starting from the chin region 8 of the mask body 1. In an adjacent to the chin area 8 Cheek area 21 of the mask body 1, the sealing lip 2 has a maximum width.
  • the cheek area 21 is located between the chin area 8 and the face bumps 12.
  • a facial abutment portion recess 19 is provided in the facial abutment portion 18, so that there, the facial abutment portion 18 has a reduced width compared to the cheek area 21.
  • the width of the facial abutment section 18 does not go to zero there.
  • the width of the facial abutment portion 18 is slightly increased in the nasal field 10 of the mask body 1 compared to the area adjacent to the facial bumps 12 again.
  • the width of the connecting portion 17 of the sealing lip 2 is substantially constant.
  • the facial abutment portion 18 has an average width B N in the region of the nose receptacle 9 between the facial cusps 12 and an average width B H in the region of the facial cusp 12.
  • B H to B N 0.1 ⁇ B n / B N ⁇ 0.9, more preferably 0.2 ⁇ B H / B N ⁇ 0.5.
  • the facial abutment portion 18 has an average width B W in the cheek area 21.
  • B W 0.05 ⁇ B H / B w ⁇ 0.6, more preferably 0.1 ⁇ B H / B w ⁇ 0.4.
  • the average width B H is 3 mm, while the average width B N is 12 mm.
  • the average width B W is 24 mm.
  • an exhalation valve 22 is used, which has an outer, flexible membrane 23. Further, two inhalation valves 24 are inserted into the side wall 5, each having a flexible membrane 25 inside. Each inhalation valve 24 is associated with an additional filter element 26, which is arranged on the outside of the mask body 1 and the respective inhalation valve 24 surrounds the outside.
  • the valves 22, 24 are preferably one-way valves.
  • a closed fastener tape (not shown) is further attached, which can be easily opened and closed by a shutter mechanism.
  • the mask body 1 is attached to the face of the wearer such that the nose of the wearer is located in the nose receptacle 9 and the chin of the wearer is in the chin area 8.
  • the bridge of the nose of the wearer preferably lies against the nose bridge 10 at least in regions.
  • the nasal wings of the wearer are preferably located at least in regions on the nostril fields 11.
