Definitions

  • the invention relates to a respiratory half mask for filtering the breathing air of a wearer of the respiratory half mask according to claim 1. Furthermore, the invention is directed to a method for producing such a respiratory half mask according to claim 14.
  • the WO 2011/142487 A1 discloses a generic foldable half mask made of a fleece laminate.
  • the mask comprises a base body and a foldable nose part and chin part connected to it. Furthermore, the mask has two side panels which, when the mask is in the finished state, are folded onto the base body and form a headband guide.
  • Another generic half mask respirator is for example from WO 96/28216 A1 previously known.
  • a half mask respirator which can be moved from a folded position into a wearing position.
  • An upper nose part and a lower chin part of the half mask respirator are connected to a base part of the half mask respirator via weld seams.
  • the US 2011/0155138 A1 discloses another respiratory half mask of the prior art which is designed as a folding mask.
  • the respiratory half mask has a base part on which an upper nose part and a lower chin part are arranged.
  • the invention is based on the object of providing an improved respiratory half mask.
  • the half mask respirator should be extremely user-friendly or easy to manufacture.
  • a corresponding manufacturing process is also to be created.
  • the partial recesses can reliably prevent an undesired fixing of the folded or folded side panels on the nose part and chin part during the production of the half mask.
  • An, in particular complete, folding of the nose part and chin part from the, advantageously flat, storage position into the respective, advantageously unfolded, carrying position is possible in this way easily and without problems, which also leads to particularly good protection for the wearer of the respiratory half mask. Leakage or damage to the respiratory protection half-mask, in particular when the side panels are fixed to the base part, can be safely avoided.
  • the base part and the chin part run adjacent or parallel to one another in the chin part storage position.
  • the base part and the nose part advantageously run adjacent or parallel to one another in the nose part storage position.
  • the half mask respirator is preferably shell-like.
  • the half mask respirator then in particular assumes a wearing position itself. It is useful if the base part, nose part and / or chin part comprises at least one stiffening means, such as a seam, clip or the like.
  • the respiratory half mask is preferably designed as a folding or folding mask. It is advantageous if the half mask respirator is symmetrical with respect to a center plane. Alternatively, the half mask respirator is asymmetrical.
  • the base part, nose part and / or chin part is preferably each multilayered.
  • the base part, nose part and / or chin part are each single-layer.
  • the base part, the nose part and the chin part are advantageously formed from an identical material. It is advantageous if the respiratory half mask is made from a filter material.
  • the filter material is, for example, a fleece material and conveniently allows breathing directly through it. The filter material filters the air you breathe. It is advantageous if the half-mask respirator can be used to filter particles or for gases and vapors.
  • the respiratory half mask can have at least one inhalation valve and / or exhalation valve. If at least one inhalation valve and / or exhalation valve is present, the base part, nose part and / or chin part can be formed from an air-impermeable material.
  • the base part, nose part and chin part are originally connected to one another in one piece and are connected to one another, for example by means of folding lines or folding lines.
  • the base part, nose part and chin part are originally designed separately and then joined together to form the half-mask body of the respiratory protection.
  • a seam can be used for joining.
  • the at least one head holding means is designed as a tape, cord or the like, for example. It is made of rubber or textile, for example. It is advantageous if the at least one head holding means is adjustable in length.
  • the head holding means receptacles are expediently completely closed on the circumference. They are preferably open at the end.
  • the at least one head holding means is expediently guided, in particular displaceably, in the head holding means receptacles. It is preferably passed through this, in particular in a displaceable manner.
  • the at least one cohesive fixing point according to dependent claim 3 is favorably a non-releasable connection. It is preferably point-shaped and / or linear. It is advantageous if the at least one material connection fixing point is formed by welding, in particular ultrasonic welding, or gluing. A welding location is preferably created by heat and / or pressure. It is advantageous if the side panels and / or the base part are temporarily softened or melted in areas in order to fix them to one another. When it cools down, the fixed connection between the base part and the respective side panel is preferably created.
  • the dimensions of the nose part-part recesses given in the dependent claims 4 and 5 allow reliable prevention of the fixing the folded side panels on the nose part. Conversely, they allow the side fields to be securely fixed on the base part.
  • the dimensions of the chin part-part recesses given in the dependent claims 8 and 9 allow a reliable prevention of the fixing of the folded-over side panels on the chin part. Conversely, they allow the side fields to be securely fixed on the base part.
  • nasal part partial recesses and chin part partial recesses are arranged in pairs or adjacent to one another and form overall recesses.
  • the respective nose part part recesses and chin part part recesses then preferably complement one another and merge into one another in order to form the overall recesses.
  • Subclaims 2 to 13 preferably also relate to advantageous configurations of the subject matter according to Claim 14.
  • Subclaims 15, 16 preferably also relate to advantageous configurations of the subject matter according to Claim 1.
  • a half-mask respirator shown in the figures comprises a half-mask body 1 and a headband 2 arranged on the half-mask body 1 for holding the half-mask body 1 on a head 3 of a wearer.
