[0017] The term "hollow body" refers, in particular, to a structurally designed, elastically deformable body with a continuous cavity. The hollow body can be deformed in a first direction, whereby pressure is applied to a first side of the hollow body and a third side of the hollow body opposite the first side, so that the detachable connection between the adapter element and the mask body and / or the detachable connection between the adapter element and the breathing air source is separated or released.

[0018] For example, the hollow body can be designed as an annular body that surrounds the hollow region in a ring-shaped manner. The annular body itself can have significantly smaller dimensions in terms of its thickness or height than its diameter or its length and width, so that the cavity formed by the hollow body can also have a significantly larger diameter or a significantly greater length and a significantly greater width than its thickness or height, which is defined by the thickness or height of the annular body. The hollow body is, in particular, designed to be closed. The hollow body has no arms with free ends. In other words, when closed, the hollow body is not designed as a clamp or the like. The closed design can have a positive effect on the stability and service life of the adapter element.

[0019] In particular, the first direction may be a direction in which a first force is applied to the hollow body. In particular, the first direction may be a direction in which the hollow body deforms upon application of the first force.

[0020] In particular, the first force is a compressive force. In particular, the first force is a force directed toward the interior of the hollow body.

[0021] In particular, the hollow body can be compressed by applying force to one side of the hollow body or to two opposite sides, whereupon the hollow body deforms in one direction. In particular, the direction in which the hollow body deforms is different from the direction or directions in which force is applied to the two opposite sides. In particular, a side of the hollow body deforms which is different from the sides to which force is applied, in particular which are compressed by applying force. In particular, the side deforms outwards, in particular away from the side of the hollow body which is opposite the deforming side. In particular, force is exerted on a first side of the hollow body and / or on a third side of the hollow body opposite the first side. In particular, force is exerted in two opposite directions.In particular, the first side and the third side are moved slightly towards one another. In particular, the hollow body is compressed at the first side and the third side. As a result, a second side of the hollow body, which is arranged in particular between the first side and the third side of the hollow body, is deformed. In particular, the second side is deformed in a direction away from the center of the hollow body, in particular in the direction opposite the center of the hollow body. In particular, the second side is deformed in a direction that is substantially perpendicular to the direction and / or directions in which force is exerted on the first side and / or the third side. In particular, the second side is deformed in a direction that is substantially perpendicular to the directions in which the first side and the third side are compressed.This allows the detachable connection between the adapter element and the mask body and / or the detachable connection between the adapter element and the breathing air source to be separated or released. Preferably, only the detachable connection between the adapter element and the breathing air source is separated or released. Preferably, the detachable connection between the adapter element and the mask body is not separated or released. In particular, the above-mentioned detachable connection is separated or released by deformation, in particular movement away, in particular bulging, in particular deflection, of only a single side of the hollow body.In particular, the hollow body is designed to deform in one direction when a first force is applied to one side of the hollow body or to two opposite sides of the hollow body such that the detachable connection between the mask body and one side of the adapter element and / or the detachable connection between one side of the adapter element and the breathing air source is separated or released, wherein the side of the adapter element whose connection to the mask body or the breathing air source is separated or released is different from the side or sides to which the first force is applied.

[0022] As already described above, the adapter element can be permanently connected to the mask body, in particular it can be designed in one piece with the mask body.

[0023] As already described above, the adapter element can be permanently connected to the breathing air source, in particular it can be designed as a single piece with the breathing air source.

[0024] By providing an elastic and closed hollow body as an adapter element that encompasses the breathing air supply cross-section, the invention enables a stable connection between the mask body and the breathing air source, as well as a simple way to detach the breathing air source from the adapter element and / or the adapter element from the mask body. The inventive design of the elastic hollow body allows the connection between the breathing air source and the adapter element to be released by simply pressing in one direction on the adapter element.

[0025] According to one embodiment of the respiratory protection mask according to the invention, the hollow body of the adapter element can be configured to deform in a first direction upon application of a first force to the hollow body such that the detachable connection between the mask body and the adapter element is severed and to deform in a second direction upon application of a second force to the hollow body such that the detachable connection between the adapter element and the breathing air source is severed.

[0026] In particular, the first direction can be a direction in which a first force is applied to the hollow body. In particular, the first direction can be a direction in which the hollow body deforms upon application of the first force. In particular, the second direction can be a direction in which a second force is applied to the hollow body. In particular, the second direction can be a direction in which the hollow body deforms upon application of the second force.

[0027] In particular, the first force and / or the second force is a compressive force. In particular, the first force and / or the second force is a force directed toward the interior of the hollow body.

[0028] Respiratory masks generally have a longer service life than filter cartridges. Filter cartridges must be replaced repeatedly over the service life of the respirator. Furthermore, respirator masks with air hoses are used. The air hose connection must also be regularly removed and reattached from the respirator. These assembly processes of the air hose connection and / or filter cartridge as the breathing air source lead to wear at the corresponding interface on the mask body. This wear, in turn, significantly shortens the service life of the mask body and thus the respirator. The invention solves this problem by providing an adapter element between the mask body and the breathing air source. This shifts the wear from the interface of the mask body to the second interface of the adapter element.

[0029] Because the hollow body of the adapter element is configured to deform in a first direction upon application of a first force to the hollow body, such that the detachable connection between the mask body and the adapter element is severed, and to deform in a second direction upon application of a second force to the hollow body, such that the detachable connection between the adapter element and the breathing air source is severed, both the connection between the mask body and the adapter element and the connection between the adapter element and the breathing air source can be easily severed. Conversely, the elastically deformable, closed hollow body also enables easy mounting of the breathing air source on the adapter element and / or the adapter element on the mask body.Overall, the present invention enables simple and efficient assembly and disassembly of the mask body and breathing air source components through the adapter element. Furthermore, the present invention enables the reduction of wear on the high-quality mask body by shifting the wear to the more cost-effective adapter element.

[0030] In this way, the adapter element can reduce the forces exerted on the respirator when connecting or disconnecting the breathing air source, thus at least reducing defects in the respirator caused by these forces. Furthermore, wear on an interface of the respirator can be reduced, for example, so that the interface of the respirator can be protected. In particular, the long-term use of the respirator can be improved by reducing the forces exerted.

[0031] Furthermore, the use of different adapter elements can make it possible to use one mask body with different types of air sources, i.e., to arrange different types of air sources on one and the same mask body. In particular, a breathing mask can be converted from a filtering breathing mask to a forced-air breathing mask and vice versa. Furthermore, the use of different adapter elements can make it possible to arrange an air source, e.g., a filter cartridge, on different mask bodies.

[0032] According to one embodiment, the first direction in which a first force is applied to the hollow body is different from the second direction in which a second force is applied to the hollow body.

[0033] The closed hollow body can, in particular, have four sides. The first direction refers, in particular, to the application of the first force to a first side of the closed hollow body. The second direction refers, in particular, to the application of the second force to a second side of the closed hollow body. The second side is, in particular, arranged offset by 90° from the first side.

[0034] The term “first direction” can have the meaning “first axis”. The application of the first force can in particular mean the application of force to a first pair of opposite sides of the closed hollow body. In this case, force, in particular compressive force, is applied to one side of the hollow body and at the same time force, in particular compressive force, is applied to the opposite side of the hollow body, with the direction of the forces being opposite. In particular, the opposite sides are pressed together along a first axis. The term “second direction” can have the meaning “second axis”. The application of the second force can in particular mean the application of force to a second pair of opposite sides of the closed hollow body.In this process, force, in particular compressive force, is applied to one side of the hollow body and, at the same time, force, in particular compressive force, is applied to the opposite side of the hollow body, with the directions of the forces being opposite. In particular, the opposing sides are pressed together along a second axis. In particular, the second pair of opposing sides is arranged at a 90° offset from the first pair of opposing sides. In particular, the second axis is arranged at a 90° offset from the first axis.

[0035] This allows for simplified assembly, as the user only needs to press in one direction, or along one axis, to release the connection between the breathing air source and the adapter element, and in another direction, or along another axis, to release the connection between the mask body and the adapter element. The required force is essentially the same. The user then simply needs to select the correct force application point to release the corresponding element.

[0036] According to one embodiment, the hollow body has a plurality of subregions over its circumference, wherein at least one subregion has a reduced cross-section compared to the other subregions, so that the at least one subregion with a reduced cross-section deforms more strongly than the other subregions when the first force and / or the second force is applied.

[0037] Furthermore, the deformation of the partial areas can also or additionally be understood as a displacement, which can lead to the detachment of the first interface or the second interface with the corresponding interface.

[0038] The hollow body can be designed in such a way that it can release a relative movement between two rigid body regions of the hollow body by bending, like a flexural joint.

[0039] The at least one partial area with a reduced cross-section provides a targeted weakening in the adapter element. This structurally provides a preferred direction for the deformation or displacement of the adapter element.

[0040] In this way, the connection between the breathing air source and the adapter element and / or the adapter element and the mask body can be released as efficiently as possible and with minimal effort.

[0041] According to one embodiment, the at least one partial region with a reduced cross-section has a concave section at one end, so that the at least one partial region with a reduced cross-section deforms more strongly than the other partial regions when the first force and / or the second force is applied.

[0042] The hollow body can be designed in such a way that, like a fixed joint of a rotary body, it can enable rotational movement between the other subregions and the subregion with a reduced cross-section, whereby the concave section can be designed as the fixed joint of a rotary body. The concave section points outward, in particular, from the center of the hollow body. In other words, the concave section represents an indentation in the hollow body or in at least one subregion.

[0043] In this way, targeted deformation can be enabled when force is applied, so that the connection can be released as easily as possible.

[0044] According to one embodiment, the hollow body has at least one first mounting bevel for the mask body and the mask body has at least one corresponding mounting bevel.

[0045] The first mounting bevel facilitates elastic deformation when mounting the adapter element on the mask body. The two mounting bevels are designed as corresponding snap-in connection elements.

[0046] In this way, efficient assembly of the adapter element on the mask body can be ensured.

[0047] According to one embodiment, the hollow body has at least one second mounting slope for the breathing air source and the breathing air source has at least one corresponding mounting slope.

[0048] The second mounting bevel facilitates elastic deformation when mounting the io breathing air source to the adapter element. The two mounting bevels are designed as corresponding snap-in connection elements.

[0049] This ensures efficient installation of the breathing air source on the adapter element. Furthermore, the adapter element can be connected to the breathing air source or the mask body in a simplified manner, such that during connection or disconnection, the interface of the breathing air source or the mask body can slide out of the first interface or the second interface of the adapter element, allowing it to be connected or disconnected with less force.

[0050] According to one embodiment, the hollow body has at least one first groove, and the mask body has at least one corresponding counterpart, which are configured to be engaged with one another. According to one embodiment, the hollow body has at least one second groove, and the breathing air source has at least one corresponding counterpart, which are configured to be engaged with one another.

[0051] The term "groove" refers specifically to an opening within the hollow body into which the corresponding counterpart of the mask body can engage. Furthermore, the groove can also be designed as a pocket. The groove can extend at least partially along the circumference of the hollow body.

[0052] The term "corresponding counterpart" refers in particular to a lug or projection arranged on the mask body or the breathing air source and designed to engage the groove. Furthermore, the corresponding counterpart can also be designed as a wedge or a spring.

[0053] In particular, all locking receptacles, in particular grooves, which receive the corresponding counterparts, in particular locking projections, in particular lugs, wedges, springs or other projections, of the breathing air source in order to attach the breathing air source to the mask body, are arranged in the adapter element or in the hollow body of the adapter element.

[0054] In particular, there are no locking receptacles in the mask body that accommodate the corresponding counterparts of the breathing air source.

[0055] In this way, for example, a tongue-and-groove connection or a tongue-and-groove connection can be realized between the hollow body and the mask body or the breathing air source, whereby such a connection can be designed for the positive connection of the hollow body to the mask body and / or the breathing air source. According to one embodiment, the at least first groove and the at least second groove are designed as a common groove.

[0056] In this way, an improved positive connection between the hollow body and the mask body or the breathing air source can be realized, so that the penetration of ambient air around the respirator can be reduced.

[0057] In particular, first locking receptacles on the hollow body for receiving the corresponding counterparts on the breathing air source are designed as at least two grooves closed on at least four sides. In particular, a second locking receptacle on the hollow body for receiving at least one corresponding counterpart on the breathing air source is designed as a web open on at least one side.

[0058] In particular, first locking receptacles on the hollow body are configured such that corresponding counterparts on the breathing air source can be inserted into them from one side. In particular, a second locking receptacle on the hollow body is configured such that at least one corresponding counterpart on the breathing air source can engage into it from above.

[0059] In this way, a simple assembly of the breathing air source on the hollow body, and thus in particular on the breathing mask, is possible and a secure hold of the breathing air source on the hollow body, and thus in particular on the breathing mask, is ensured.

[0060] According to one embodiment, the breathing air source is a filter cartridge.

[0061] In this way, the respiratory mask can be designed in particular to supply a person wearing the respiratory mask with filtered ambient air.

[0062] According to one embodiment, the breathing air source is an air hose coupling.

[0063] In this way, the respiratory mask can be designed in particular to supply a person wearing the respiratory mask with breathing air that is independent of the ambient air.

[0064] According to one embodiment, the mask body has a first laterally open channel segment as a strap guide of a headband, and the adapter element has a second laterally open channel segment as a strap guide of a headband, wherein the second laterally open channel segment forms a strap guide channel in a state in which the adapter element is connected to the mask body.

[0065] The terms “first laterally open channel segment” and “second laterally open channel segment” refer in particular to a surface designed to guide the headband such that, for example, the headband can be guided over the first laterally open channel segment and / or the second laterally open channel segment. The first laterally open channel segment and / or the second laterally open channel segment can be designed such that the headband coming from a first point on the head of a person wearing the respiratory mask can be guided over the first laterally open channel segment and / or the second laterally open channel segment in order to be guided back to a second point on the head, such that the respiratory mask can be held over at least the first point and the second point on the head. The juxtaposition of the channel segments can form the strap guide channel.

[0066] In this way, a headband guide integrated into the respirator mask can be realized, which improves the wearing comfort of the respirator mask and / or the sealing of the respirator mask against the ambient air of the respirator mask.

[0067] Another aspect concerns the use of a filter cartridge in a respiratory mask as described above.

[0068] Another aspect concerns the use of a mask body in a respiratory mask as described above.

[0069] A further aspect relates to the use of a closed elastically deformable hollow body for connecting a filter cartridge or an air hose coupling or a mask body in a respiratory mask described above.

[0070] A further aspect relates to an adapter element for connecting a breathing air source to a mask body, wherein the adapter element has a first interface for detachably connecting the adapter element to a mask body and / or a second interface for detachably connecting the adapter element to a breathing air source; wherein the adapter element has a closed hollow body that is elastically deformable along its circumference and is configured to deform in a first direction upon application of a first force to the hollow body such that a detachable connection between a mask body and the adapter element and / or a detachable connection between the adapter element and a breathing air source is severed.

[0071] In one embodiment of the adapter element according to the invention, the adapter element is permanently connected to a mask body, in particular it is designed in one piece with a mask body.

[0072] In one embodiment of the adapter element according to the invention, the adapter element is permanently connected to a breathing air source, in particular it is designed in one piece with a breathing air source.

[0073] In one embodiment of the adapter element according to the invention, the hollow body of the adapter element is configured to deform in a first direction upon application of a first force to the hollow body such that a detachable connection between a mask body and the adapter element is severed, and to deform in a second direction upon application of a second force to the hollow body such that a detachable connection between the adapter element and a breathing air source is severed.

[0074] In particular, said first direction is different from said second direction.

[0075] The features described above, including those from different embodiments, can also be combined with each other, resulting in synergistic interactions that go beyond the sum of the individual effects.

[0076] The above statements regarding the respiratory mask according to the invention can apply analogously to the adapter element according to the invention.

[0077] The invention is explained below using exemplary embodiments, which are described with reference to the following figures:

[0078] Figure 1 shows an exemplary representation of a respiratory mask according to the invention;

[0079] Figure 2 shows an exemplary representation of an adapter element according to the invention in a first view;

[0080] Figure 3 shows an exemplary representation of an adapter element according to the invention in a second view;

[0081] Figure 4 shows an exemplary representation of a mask body according to the invention; and

[0082] Figure 5 shows an exemplary representation of a filter cartridge according to the invention.

[0083] Exemplary embodiments are described and explained below with reference to the figures listed above. Like reference symbols or analogous reference symbol structures refer to analogous or interacting components.

[0084] Figure 1 shows an exemplary representation of a respiratory mask 10 according to the invention. The respiratory mask 10 is arranged on a user's head 12. The respiratory mask 10 has a mask body 20. The respiratory mask 10 has a filter cartridge 30 as the breathing air source. The respiratory mask 10 has an adapter element 40 for connecting the filter cartridge 30 to the mask body 20. The respiratory mask 10 also has a second filter cartridge 70, which is also connected to the mask body 20 via a second adapter element 71. The respiratory mask 10 is fastened to the head 12 by a headband 11. The headband 11 is guided in a band guide channel 54. The band guide channel 54 is formed by a first laterally open channel segment 24 of the mask body 20 and a second laterally open channel segment 53 of the adapter element 40.The respirator mask 10 allows the user to inhale ambient air through the filter cartridges 30 and 70. The ambient air is filtered and purified by the filter cartridges 30 and 70 of potentially harmful substances, particularly gases, vapors, and / or particles. Alternatively, instead of a filter cartridge as the breathing air source, an air hose coupling (not shown) can be indirectly connected to the mask body 20 via the adapter element 40.

[0085] Figures 2 and 3 show an exemplary representation of an adapter element 140 according to the invention in two different views. The two views are described together here. The adapter element 140 has a first interface 141 for detachably connecting the adapter element 140 to a mask body (not shown). The adapter element 140 has a second interface 142 for detachably connecting the adapter element 140 to a breathing air source (not shown).

[0086] Furthermore, the adapter element 140 has a closed hollow body 143 that is elastically deformable along its circumference and is configured to deform in a first direction upon application of a first force to the hollow body 143 such that the detachable connection between the mask body (not shown) and the adapter element 140 is severed and / or to deform in a second direction upon application of a second force to the hollow body 143 such that the detachable connection between the adapter element 140 and the breathing air source (not shown) is severed. When force is applied to the partial regions 144 and 146, the connection between the adapter element 140 and the filter cartridge is released, in particular because the partial region 145 moves outward, in particular in the radial direction away from the center of the hollow body 143.When force is applied to the partial areas 145 and 147, a connection between the adapter element and the mask body is released, in particular because the first interface 141 moves outwards, in particular in the radial direction away from the center of the hollow body 143. Thus, by simply pressing on two opposite sides, the mask body or the filter cartridge or the air hose coupling can be released from the adapter element. As a result of the pressing, the closed elastic hollow body deforms in such a way that the locking connections between the adapter element and the mask body and / or the locking connections between the adapter element and the filter cartridge are released or released. Furthermore, the hollow body 143 has at least one first mounting bevel 149 for the mask body (not shown).
