Definitions

  • the present invention relates to a respiratory protection half mask having a mask body having a soft elastic base and a carrier at least partially disposed inside the base.
  • the carrier has a front element which has a first connection and has lateral elements which are arranged toward the two sides of the front element, the lateral elements each having two interfaces.
  • the first and second interfaces are designed to secure different components of the respiratory protection mask, such as filter elements, exhalation valves, communication membranes and/or external air supply means, to the first and second interfaces.
  • BACKGROUND OF THE INVENTION Half masks for use in mild respiratory protection are well known and are typically provided with replaceable particles and/or gas filters.
  • a half mask which is different from the full face mask and covers only the mouth of the wearer and the nose, is fixed to the wearer's head by means of a band.
  • the strip is fastened to the mask body of the face of the wearer of the mask via a suitable fastening element, wherein a clamping element which is generally suitable for this is provided on the mask body and on the holding element.
  • the mask body itself has essentially two functions. On the one hand, the mask body has a bearing surface which should be as sealing as possible and at the same time comfortably abut the wearer's face, so as to ensure not only a reliable sealing of the mouth and nose space, but also at least a pressure point on the wearer's face.
  • the mask body typically consists of two main components, namely a rigid member for accommodating the filter and a soft member that ensures that the mask is sealingly and comfortably placed on the face of the wearer of the mask.
  • the mask body is either manufactured as a one-piece or two-part injection molded part, or the mask of the half mask is assembled from different parts.
  • a respiratory protection half-mask with a mask body having a soft-elastic base body with reinforcing elements each of which is made of hard plastic and arranged therein is known from DE 10 2007 055 241 B4.
  • the described mask body should ensure a high degree of wearing comfort for the mask wearer and, on the other hand, ensure a reliable and shape-accurate fastening of the filter or the exhalation valve with the holding device for the strip. Since the three reinforcing elements of the previously described mask body are not interconnected, the mask body is absolutely soft and of course relatively costly for the tools required for manufacture.
  • this undesired movement of the filter mainly occurs because the soft-elastic base of the mask body must partially absorb significant forces or moments due to the weight of the filter.
  • a respiratory protection half mask having the features specified in claim 1.
  • Advantageous embodiments of the invention are the subject matter of the dependent claims and are explained in detail in the following description in the context of a partial reference to the drawings.
  • a respiratory protection half mask having a mask body having a soft-elastic base body and a carrier at least partially arranged inside the base body, wherein the carrier element has a front side element and lateral sides respectively arranged on both sides thereof
  • the component, and the frontal component and the lateral component respectively have a connection structure on which each respiratory protection component can be fixed as desired, in particular an exhalation valve, a filter element, a communication membrane and/or an external air supply device
  • the respiratory protection half mask is thus modified such that the lateral elements are hingedly connected to the front element via hinges, respectively.
  • the articulated connection between the front element and the two lateral elements ensures that the front element of the carrier and the lateral element with the filter interface arranged laterally can be moved in a defined direction, from The mask body as a whole is softly matched to the respective facial shape of the wearer without undesired movement in the lateral direction, in particular the movement of the relatively heavy filter element.
  • the solution according to the invention which is characterized in that the two-part mask body consisting of a relatively rigid carrier and a soft-elastic base body, achieves a half-mask with suitable flexibility, which simultaneously corresponds to Mask sealing placement and wearing comfort requirements.
  • the rigidity of the carrier in the vertical direction is important, thus enabling or simplifying the carrying and mounting of some of the heavier gas and/or particulate filters.
  • the hinge is formed in the interior of the carrier in the form of a material thinning that is suitable for the introduction of the material between the front side and the side element.
  • material thinning can involve point-like and/or linear material recesses or material points that are punctiform and/or linear.
  • the hinge is designed as a film hinge between the front element and the lateral element.
  • film hinges are well known within the scope of plastic technology, for example in food packaging.
  • the provision of a suitable film hinge ensures that a defined bending surface is provided on the one hand and that the hinge can be produced in a relatively simple manner on the other hand.
  • the carrier it is conceivable for the carrier to be integrated at least almost completely into the basic body, and that the basic body has suitable openings for the required respiratory protection components, for example filter elements, exhalation valves, The interface of the talk film and/or the external air supply means and/or can be accessed via the opening.
  • the base body it is preferred for the base body to have an at least approximately circular opening through which a suitable cylindrical connecting region of the carrier extends.
  • a contour on the cylindrical connecting region of the carrier which contour can be used to fix the respectively required respiratory protection component, in particular in the orientation provided for this purpose, or For example, a transition of the seal between the carrier and the filter element and/or the exhalation valve.
  • a part of the exhalation valve, in particular a dedicated diaphragm is arranged inside the connection region of the carrier and is arranged here in a suitable manner.
  • the diaphragm in the flow channel of the exhaled air during operation of the mask can be advantageously integrated into the front element, preferably into the annular cylinder forming the flow channel for exhaled air.
  • the annular hollow cylinder preferably has a connection profile for the exhalation valve or a flow channel for the retaining element of the strip.
  • the soft-elastic base body has at least one fastening means which can be connected directly or indirectly to the strip of the respiratory protection half-mask. Preferably, via a suitable holding mechanism The strip is attached to the mask body.
  • the locking element is arranged on the soft-elastic base body of the mask body, which can be introduced into a corresponding corresponding contour of the holding element of the strip for the half mask.
  • the base body is designed to be soft-elastic in order to achieve a sealing arrangement on the wearer's face on the one hand and a comfortable wearing comfort on the other hand.
  • the matrix is preferably a thermoplastic elastomer in a preferred manner. Preference is given to using polypropylene (PP) which is particularly preferably filled with glass fibers.
