Description

The invention relates to a breathing mask holding part for holding a breathing half mask. Furthermore, the invention is directed to a respirator arrangement with such a respirator holding part and to a respirator half mask as part of such an respirator arrangement.

Respiratory half masks have proven their worth in practice. A disadvantage of the respiratory protection half masks of the prior art is that they often do not lie tightly or not sufficiently close to the wearer of the respiratory protection half mask or to his face. Leakage often occurs when wearing the half-face mask, especially in connection with safety glasses, which can be dangerous or harmful to the health of the wearer.

From the DE 29 38 720 A1 Respiratory half masks with a mask body are known, which is welded to a sealing lip and a reinforcing frame. In a preferred embodiment, the reinforcement frame has a protruding tab on each side for fastening headbands. The tabs have cutouts with a rag to unbutton the headbands with holes.

The DE 661 719 discloses a mask holding basket in which a mask is detachably arranged. At one edge of the mask-holding basket, slit-like eyelets are arranged, on which fastening straps for binding or hooking behind the neck are attached.

The US 2012/0042878 A1 discloses a mask arrangement with a mask outer body and a mask main body, which can be fixed to the mask outer body by means of a coupling element. The mask outer body has two headband threading sections on the side, each of which has four threading cutouts and three deflection bars.

From the GB 978,962 a health mask is known which comprises a carrying element for wearing a mask body. The support body comprises three slots on each side through which a headband can run.

From the EP 1 514 581 A2 a breathing mask is known which comprises a filter body, headband adjustment means and a headband.

The invention has for its object to provide a breathing mask holding part for holding a breathing half mask, which offers the wearer on the one hand a particularly high level of protection, in particular in connection with protective glasses, and on the other hand enables extremely economical or environmentally compatible breathing protection.

First referring to the Fig. 1 and 2nd A respirator arrangement comprises a respirator holding part 1 and a respirator half mask 2 which is fixed in position on the respirator holding part 1, as well as exactly one headband 3 attached to the respirator holding part 1.

If the respirator arrangement is intended to be worn by a wearer (not shown), the respirator half mask 2 covers the nose area and the mouth area of the wearer. The headband 3 is guided around the back of the wearer's head and holds the respiratory mask holding part 1 and thus also the respirator half mask 2 attached to the face of the wearer. The respiratory mask holding part 1 then has a face region 4 facing the face of the wearer. The respirator half mask 2 lies closely against the face of the wearer.

The terms "front", "front", "rear", "back" or the like used here refer to this intended arrangement of the breathing mask arrangement on the face of the wearer.

The headband 3 is flexible and closed on the circumference. It has a constant constant height HH perpendicular to its longitudinal or circumferential direction. The headband 3 also has a constant constant thickness D perpendicular to its longitudinal direction or circumferential direction.

The breathing mask holding part 1 has a frame body 5, which is symmetrical with respect to a plane of symmetry 6 and is web-like. The frame body 5 delimits a respiratory protection half mask receptacle 7 to the side and is closed in a circumferential direction.

The breathing mask holding part 1 has a lower chin area 8 and an upper nose area 9, which is arranged essentially opposite to the lower chin area 8. The breathing mask holding part 1 is essentially V-shaped in the nose region 9. It widens there in the direction of the chin area 8. The chin area 8 is convexly curved in relation to the inner respiratory protection half-mask receptacle 7. The nose of the wearer can be received in the nose area 9, while the chin of the wearer is then in use in the chin area 8.

The breathing mask holding part 1 also has two lateral cheek regions 10 which are arranged opposite one another. The cheek areas 10 are located essentially below the nose area 9 and above the chin area 8. More specifically, the cheek areas 10 are provided essentially obliquely outside below the nose area 9 and obliquely outside above the chin area 8. The plane of symmetry 6 passes through the chin area 8 and the nose area 9. It runs centrally between the cheek areas 10.

As already mentioned, the frame body 5 is designed like a web. It thus has a frame wall 11. The frame wall 11 jumps forward from the face area 4 in a front direction 12, which corresponds to a direction of view of the wearer when the breathing mask arrangement is worn as intended. In the chin area 8 and the nose area 9, the frame wall 11 has flexible areas 9a in the face area 4.

In each cheek area 10, the breathing mask holding part 1 has a headband holding device 13, which is firmly connected to the frame body 5. Each headband holding device 13 has a base 14 which adjoins the frame body 5 laterally on the outside in the face region 4. The bottoms 14 are essentially plate-like and are essentially on a common level. They can also be slightly inclined to each other.

Each headband holding device 13 also has two retaining projections 15, each of which is essentially identical. The retention projections 15 each jump forward from the respective floor 14 in the front direction 12. More specifically, they protrude diagonally inwards towards the plane of symmetry 6. It is advantageous if the retaining projections 15 each taper from the respective base 14.

Each retaining projection 15 has a retaining body 16 designed in the manner of a plate, which protrudes forward from the base 14 essentially parallel to an adjacent region of the frame body 5 in the front direction 12. The retention bodies 16 each run at a distance from the respective adjacent area of the frame body 5, forming a respective headband part receptacle 17.

Each retaining body 16 carries at its free end 18 facing away from the respective floor 14 a retaining lug 19 which projects inward from the respective retaining body 16 in the direction of an adjacent region of the frame body 5. The retention lugs 19 are spaced apart from the respective adjacent floor 14. They are located at a height below a free end 20 of the respectively adjacent area of the frame body 5. The retaining lugs 19 end adjacent to the frame body 5 and in each case limit the headband part receptacles 17 to the front in the front direction 12.

In each retaining lug 19 there is a receiving slot 21 which is open to the adjacent floor 14 and widens in the direction of this floor 14. Each retaining lug 19 has a roof web 22 which delimits the respective receiving slot 21 in the height or front direction 12. Each headband part receptacle 17 has a height HK which essentially corresponds to the height HH of the headband 3. The height HK is limited on the one hand by the floor 14 and on the other hand by the adjacent roof web 22. Adjacent to the roof web 22, each receiving slot 21 has a minimum slot width SW, which essentially corresponds to the thickness D of the headband 3.

The headband part receptacles 17 of a headband holding device 13 together form a headband receptacle.

Between the two retaining projections 15 of a headband holding device 13, a plate-shaped coupling part 23 projects from the floor 14 in the front direction 12. In turn, a mushroom-shaped fastening means 24 jumps laterally outward from each coupling part 23, that is to say laterally away from the frame body 5. The fastening means 24 thus jump away from one another or from the plane of symmetry 6.

Each fastening means 24 has a cylindrical fastening pin 25 which laterally adjoins the coupling part 23 and a retaining head 26 which projects radially with respect to the fastening pin 25. The coupling parts 23 are arranged with respect to the frame body 5 outside a direct connecting line between the retaining projections 15 of a headband holding device 13.

In the area of each retaining projection 15, a disassembly opening 27 is arranged in the respiratory mask holding part 1, which is slightly larger in shape and size than the adjacent retaining projection 15. The disassembly openings 27 penetrate the frame body 5 and also the adjacent floor 14, so that the disassembly openings 27 are open inwards in the direction of the plane of symmetry 6 and counter to the front direction 12.

The respiratory protection half mask 2 has a mask body 28 which is designed as a shell-shaped molded body made of a non-woven material. The size and shape of the mask body 28 is adapted to the breathing mask holding part 1, in particular to its breathing mask half mask receptacle 7. The respiratory protection half mask 2 is symmetrical with respect to a plane of symmetry 32.

The mask body 28 thus has an upper nose region 29, a chin region 30 opposite the upper nose region 29 and two mutually opposite cheek regions 31 between the nose region 29 and the chin region 30.

At the edge, the mask body 28 has a circumferential, outer sealing web 33 for abutment against the face of the wearer.

Furthermore, the respiratory half mask 2 comprises two lateral, opposite fastening tabs 34, which are preferably formed from a nonwoven material. The fastening tabs 34 are in the cheek regions 31 with the sealing web 33 in direct connection. They are flexible and / or foldable along the adjacent sealing web 33. The fastening tabs 34 are permanently connected to the mask body 28. In each fastening tab 34 there is a fastening opening 35, which is, for example, slit-shaped. Each fastening opening 35 is essentially adapted to the cross section of the respective fastening pin 25 or is capable of essentially adapting to this cross section.

The breathing mask arrangement is described in more detail below in the assembled state. In the assembled state of the respiratory mask arrangement, the respiratory half mask 2 is inserted into the respiratory mask holding part 1. The sealing web 33 runs along the face area 4 of the breathing mask holding part 1, while the mask body 28 passes through the breathing area half mask receptacle 7 from the face area 4 in the front direction 12 and protrudes from the frame body 5 in the front direction 12. The mask body 28 lies adjacent to the sealing web 33 on the inside against the frame wall 11. In use, the sealing web 33 lies against the face of the wearer.

In order to fix the respiratory protective half mask 2 on the respiratory protective mask holding part 1, the fastening tabs 34 are folded forward so that they protrude from the sealing web 33 in the front direction 12. The fastening tabs 34 are then pivoted further inwards in the direction of the plane of symmetry 32, so that the fastening means 24 pass through the fastening openings 35. The fastening openings 35 preferably widen briefly. The retaining heads 26, which then overlap the fastening openings 35, hold the fastening lugs 34 securely on the fastening pins 25. The respiratory protection half mask 2 can thus be detached from the respiratory mask holding part 1 fixed. The respiratory half mask 2 can be removed in the opposite manner from the respiratory mask holding part 1.

The headband 3 can then be fixed locally on the two headband holding devices 13. For this purpose, the headband 3 is moved / threaded against the front direction 12 between the respective retaining lug 19 and the adjacent frame wall 11 in the direction of the respective floor 14 until the headband 3 is adjacent to the respective floor 14 or at least partially abuts against it. The edge of the headband 3 facing away from the bottom 14 is then inserted in the front direction 12 into the respective receiving slot 21, so that the headband 3 is fixed locally on the respective retaining projection 15. The headband 3 then runs essentially straight in the respective headband holding device 13 between the two adjacent retaining projections 15 and runs between the retaining projections 15 and the adjacent frame wall 11. The headband 3 also runs past the respective coupling part 23 on the inside. At least in regions, it can bear against the retaining projections 15 on the inside or against the frame wall 11 on the outside. In the attached state, all retaining projections 15 hold onto the headband 3.

The removal of the headband 3 from the breathing mask holding part 1 takes place in the reverse manner. For this purpose, the headband 3 is moved out of the receiving slots 21 against the front direction 12 and is removed in the front direction 12 between the frame wall 11 and the retaining lugs 19. The headband 3 is accessible in the area of the retaining projections 15 via the dismantling openings 27, so that the removal can be supported or the headband 3 can temporarily escape into these dismantling openings 27 during removal.
