Definitions

  • the invention relates to an escape filter device with a protective hood, according to the preamble of claim 1.
  • a known protective device against air pollution consists of at least one hood, which has a respirator with a filter.
  • the respirator mask and the filter are connected to each other by a connecting piece penetrating the protective hood.
  • the wearer breathes in through the filter and exhales into the interior of the hood through an opening in the face part of the respirator.
  • the exhaled air then flows out through leaks between the hood and the body parts of the wearer. It creates an air curtain that prevents unfiltered outside air from entering the interior of the hood.
  • the object of the invention is a simple escape filter device with a protective hood that provides safe breathing air conditions for the wearer in emergency situations and is suitable for all existing head sizes as well as for glasses and beard wearers.
  • the advantages of the escape filter device according to the invention lie in the design of the half-mask body with the face contact surface.
  • the face support surface fits broadly on the facial areas. It bridges the different head sizes and face shapes.
  • the profile design below the face support surface within the half-mask body creates a system pressure that is the same everywhere, which guarantees a safe system.
  • the large contact surfaces with the then small specific contact pressure are extremely comfortable for the wearer.
  • the strap can be tightened vigorously without bothering the wearer. This favors a dense plant.
  • the escape filter device consists of the protective hood 1 with the elastic neck brace 2. It can consist of one visible film, but also consist of other material. If this is not transparent, then the window section 3 is incorporated.
  • the half-mask body 4 is arranged opposite the nose and mouth area of the wearer. It penetrates tightly through the protective hood 1 with the receptacle 5 for the filter 6.
  • the protective hood 1 has lateral eyelets 7 for receiving the strap 8 a known quick adjustment can be tightened and held over the neck.
  • the face support surface 10 is pulled tight against the parts of the face.
  • the shape of the face part of the half-mask body 4 is shown in FIG. 2.
  • the cutout 11 for the nose and mouth area is relatively small in relation to the outer circumference 12 of the half-mask body 4.
  • the sealing on the face takes place via the large face contact surface 10.
  • the everywhere equally large, but comfortable contact pressure is achieved by the special design of the face part below the face support surface 10.
  • 3 shows the triangular support profile 13, which continues along the entire cutout 11 with a changing cross-sectional area. It can be made of foamed material and then filled or, as drawn in dashed lines, it can be a hollow body with walls.
  • 4 shows a further embodiment in which one side of the triangle has been omitted.
  • the sufficient rigidity of the face support surface 10 is achieved by means of intermediate walls 14 arranged at a distance from one another.
  • the section D-E in Fig. 5 shows that the support profiles 13 end in a lip-shaped system 15, which securely rests against the bridge of the nose.
