Description

Die Erfindung betrifft eine Atemschutzmaske mit einem Maskenkörper, mit mindestens einem Ausatemventil und mindestens einem Einatemventil, mit mindestens einem dem Einatemventil zugeordneten Filtermodul, und mit wenigstens einem an dem Maskenkörper angeordneten Koppelelement zur Befestigung mindestens eines den Kopf eines Benutzers hintergreifenden Kopfbefestigungsbandes an dem Maskenkörper.The invention relates to a respiratory mask with a mask body, with at least one exhalation valve and at least one inhalation valve, with at least one filter module associated with the inhalation valve, and with at least one arranged on the mask body coupling element for attaching at least one head of a user behind the head engaging band on the mask body.

Atemschutzmasken der Eingangs genannten Art sind aus dem Stand der Technik bekannt. Sie werden dazu verwendet, einen Benutzer beim Atmen vor Luftverunreinigungen zu schützen. Mittels eines über Mund und Nase des Benutzers anordenbaren Maskenkörper wird ein geschlossener Gasraum für den Benutzer gebildet, der von der Umgebung getrennt ist. Mithilfe von wenigstens einem Ausatemventil und wenigstens einem Einatemventil, die beide an dem Maskenkörper angeordnet sind und diesen durchdringen, kann dann ein Gas- beziehungsweise Luftaustausch zwischen dem Benutzer und der Umgebung durch den Maskenkörper hindurch stattfinden. Üblicherweise weisen die Maskenkörper darüber hinaus Koppelelemente auf, an welchen ein oder mehrere Kopfbefestigungsbänder befestigbar sind, die um den Hinterkopf des Benutzers gespannt die Atemschutzmaske gegen das Gesicht des Benutzers ziehen, um ein dichtes Anliegen der Atemschutzmaske am Gesicht zu gewährleisten.Respirators of the type mentioned are known from the prior art. They are used to protect a user from air pollution during breathing. By means of an over the mouth and nose of the user can be arranged mask body a closed gas space for the user is formed, which is separated from the environment. By means of at least one exhalation valve and at least one inhalation valve, both of which are arranged on the mask body and penetrate it, then a gas or air exchange between the user and the environment can take place through the mask body. Usually, the mask bodies also have coupling elements to which one or more head attachment straps can be fastened, which, stretched around the back of the user's head, pull the respiratory mask against the user's face in order to ensure a close fit of the respiratory mask on the face.

Um die eingeatmete beziehungsweise einzuatmende Luft von gegebenenfalls vorhandenen Verunreinigungen zu trennen, ist dem wenigstens einen Einatemventil beziehungsweise jedem Einatemventil jeweils ein Filtermodul zugeordnet, durch welches die Luft strömen muss, bevor sie den Gasraum und insbesondere das Einatemventil erreicht. Um die Atemschutzmaske über einen langen Zeitraum benutzen zu können, insbesondere auch dann, wenn die Filtermodule Alterungserscheinungen aufweisen, ist es erforderlich, das oder die Filtermodule bei Bedarf auswechseln zu können. Hierzu sind bereits unterschiedliche Lösungen bekannt.To separate the inhaled or inhaled air from any impurities present, the at least one inhalation valve or each inhalation valve is assigned in each case a filter module through which the air flow must before it reaches the gas chamber and in particular the inhalation valve. In order to use the respirator over a long period of time, especially if the filter modules have aging, it is necessary to be able to replace the filter modules or if necessary. For this purpose, different solutions are already known.

Aus der US 5,222,488 B1 ist beispielsweise eine Atemschutzmaske bekannt, bei welcher ein Filtermodul an einen Maskenkörper aufschraubbar ist. Und aus der US 4,934,361 B1 geht bereits eine Atemschutzmaske hervor, bei welcher das Filtermodul mittels eines Bajonettverschluss an dem Maskenkörper lösbar befestigt werden kann. Weiterhin ist es aus der US 4,771,771 B1 bereits bekannt, eine Schiebesitzvorrichtung zum lösbaren Halten eines Filtermoduls vorzusehen.From the US 5,222,488 B1 For example, a respirator is known in which a filter module is screwed to a mask body. And from the US 4,934,361 B1 already shows a respirator, in which the filter module can be releasably secured by means of a bayonet lock on the mask body. Furthermore, it is from the US 4,771,771 B1 already known to provide a sliding seat device for releasably holding a filter module.

Aus der Offenlegungsschrift US 2003/029454 A1 ist bereits eine Atemschutzmaske der gattungsgemäßen Art bekannt, bei welcher ein Filtermodul lösbar befestigt werden kann, wobei an dem Maskenkörper ein Koppelelement zur Befestigung eines Kopfbefestigungsbandes sowie ein Befestigungsmittel zur lösbaren Befestigung des Filtermoduls angeordnet sind. Das Befestigungsmittel weist einen Haltevorsprung auf, der in Eingriff und außer Eingriff mit dem Maskenkörper bringbar und an einem Befestigungsrahmen des Filtermoduls ausgebildet ist.From the publication US 2003/029454 A1 already a respirator of the generic type is known in which a filter module can be releasably attached, wherein on the mask body, a coupling element for fixing a head mounting band and a fastening means for releasably securing the filter module are arranged. The fastening means has a retaining projection engageable and disengageable with the mask body and formed on a mounting frame of the filter module.

Die bekannten Atemschutzmasken haben den Nachteil, dass zur lösbaren Befestigung des einen oder der mehreren Filtermodule aufwändig gestaltete Befestigungsmittel an dem Maskenkörper vorgesehen werden müssen.The known respirators have the disadvantage that for the releasable attachment of the one or more filter modules elaborately designed attachment means must be provided on the mask body.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Atemschutzmaske zu schaffen, die auf einfache und kostengünstige Art und Weise die oben genannten Nachteile überwindet.The invention is therefore an object of the invention to provide a respirator, which overcomes the disadvantages mentioned above in a simple and cost-effective manner.

Die der Erfindung zugrundeliegende Aufgabe wird durch eine Atemschutzmaske mit den Merkmalen des Anspruchs 1 gelöst. Diese hat den Vorteil, dass bereits üblicherweise an der Atemschutzmaske vorgesehene Elemente auf einfache Art und Weise dazu genutzt werden, gleichzeitig auch eine lösbare Arretierung des oder der Filtermodule an dem Maskenkörper zu gewährleisten. Ohne großen zusätzlichen Aufwand wird dabei eine lösbare Befestigung des oder der Filtermodule an dem Maskenkörper erreicht. Die erfindungsgemäße Atemschutzmaske zeichnet sich dadurch aus, dass das Koppelelement zur lösbaren Befestigung des Filtermoduls an dem Maskenkörper wenigstens einen Haltevorsprung aufweist, der von einer das Filtermodul an dem Maskenkörper arretierenden Position in eine das Filtermodul freigebende Position verlagerbar ist. Die Erfindung sieht also vor, dass das sowieso üblicherweise vorhandene Koppelelement auch zur Befestigung des Filtermoduls genutzt wird. Durch Verlagern des an dem Koppelelement angeordneten Haltevorsprungs von einer arretierenden Position in eine freigebende Position lässt sich das Filtermodul von dem Maskenkörper lösen. Durch entsprechendes Verlagern des Haltevorsprungs von der freigebenden Position in die arretierende Position wird das Filtermodul am Maskenkörper befestigt.The problem underlying the invention is achieved by a respirator with the features of claim 1. This has the advantage that already conventionally provided on the respirator elements are used in a simple manner to simultaneously ensure a releasable locking of the filter or modules to the mask body. Without great additional effort while a detachable attachment of the filter or modules is achieved on the mask body. The respirator mask according to the invention is characterized in that the coupling element for releasable attachment of the filter module to the mask body has at least one holding projection which can be displaced from a position locking the filter module to the mask body into a position releasing the filter module. The invention thus provides that the coupling element, which is normally present anyway, is also used for fastening the filter module. By displacing the holding projection arranged on the coupling element from a locking position into a releasing position, the filter module can be detached from the mask body. By corresponding displacement of the holding projection from the releasing position into the arresting position, the filter module is fastened to the mask body.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass das Koppelelement zumindest bereichsweise elastisch verformbar ausgebildet ist. Hierdurch wird vorteilhafterweise erreicht, dass durch elastische Verformung des Koppelelements der daran angeordnete Haltevorsprung aus der einen in die andere Position verlagerbar ist. Hierdurch wird eine besonders einfache Realisierung der Verlagerbarkeit des Haltevorsprungs gewährleistet. Besonders bevorzugt ist das Koppelelement einstückig mit dem Maskenkörper oder mit einem Maskenkörperteil des gegebenenfalls mehrteilig ausgebildeten Maskenkörper ausgebildet.According to a preferred embodiment of the invention it is provided that the coupling element at least partially elastic is formed deformable. This advantageously achieves that by elastic deformation of the coupling element of the retaining projection arranged thereon can be displaced from one to the other position. This ensures a particularly simple realization of the displaceability of the retaining projection. Particularly preferably, the coupling element is formed integrally with the mask body or with a mask body part of the optionally multi-part mask body.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass zusätzlich oder alternativ das Koppelelement durch ein Gelenk an dem Maskenkörper verschwenkbar gelagert ist. In diesem Fall ist das Koppelelement also gelenkig mit dem Maskenkörper verbunden, wobei in diesem Fall dem Gelenk bevorzugt wenigstens ein Federelement zugeordnet ist, das das Koppelelement mit dem Haltevorsprung bevorzugt in die arretierende Position drängt, so dass im Normalzustand das Filtermodul an dem Maskenkörper gehalten ist. Entsprechendes gilt vorzugsweise auch für die Ausbildung des elastisch verformbaren Koppelelementes, das in der arretierenden Stellung entweder entspannt oder bereits vorgespannt ist, um einen besonders sicheren und spielfreien Halt des Filtermoduls an dem Maskenkörper zu gewährleisten.According to an advantageous embodiment of the invention it is provided that additionally or alternatively, the coupling element is pivotally mounted by a hinge on the mask body. In this case, the coupling element is thus hingedly connected to the mask body, in which case the joint is preferably associated with at least one spring element which preferably urges the coupling element with the holding projection in the arresting position, so that in the normal state, the filter module is held on the mask body , The same applies preferably also for the formation of the elastically deformable coupling element, which is either relaxed in the locked position or already biased to ensure a particularly safe and backlash-free hold of the filter module to the mask body.

Bevorzugt ist vorgesehen, dass der Haltevorsprung einstückig mit dem Koppelelement ausgebildet ist. Hierdurch ergibt sich eine besonders einfache und stabile Anordnung des Haltevorsprungs an dem Koppelelement.It is preferably provided that the holding projection is formed integrally with the coupling element. This results in a particularly simple and stable arrangement of the retaining projection on the coupling element.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Haltevorsprung als Rastnase mit einem dem Masken körper zugewandten Anschlag und mit einer von dem Maskenkörper abgewandten Einführschräge ausgebildet ist. Durch die Einführschräge wird das Koppelelement zusammen mit dem Haltevorsprung automatisch in die freigebende Position verlagert, wenn das Filtermodul an den Maskenkörper herangeführt wird. Vorzugsweise weist der Maskenkörper eine Aufnahmevertiefung zur zumindest bereichsweisen Aufnahme des Filtermoduls auf, in welche das Filtermodul bevorzugt zumindest im Wesentlichen passgenau einsetzbar ist. Vorteilhafterweise ist am Rande dieser Vertiefung das zumindest eine vorteilhaft ausgebildete Koppelement mit dem Haltevorsprung vorgesehen, so dass durch die Aufnahmevertiefung eine sichere Platzierung des Filtermoduls an der gewünschten Stelle und durch das Koppelelement eine sichere Arretierung des Filtermoduls an dem Maskenkörper erfolgt.According to an advantageous embodiment of the invention it is provided that the retaining projection as a latching nose with a masks body facing stop and is formed with a facing away from the mask body insertion. Due to the insertion bevel, the coupling element is automatically displaced together with the holding projection in the releasing position when the filter module is brought to the mask body. Preferably, the mask body has a receiving recess for at least partially receiving the filter module, in which the filter module is preferably used at least substantially accurate fit. Advantageously, the at least one advantageously designed coupling element is provided with the holding projection on the edge of this depression, so that through the receiving recess a secure placement of the filter module at the desired location and by the coupling element is a secure locking of the filter module to the mask body.

Ferner ist bevorzugt vorgesehen, dass das Koppelelement L-förmig ausgebildet ist, mit einem ersten an dem Maskenkörper befestigten Schenkel und mit einem zweiten von dem Filtermodul wegweisenden Schenkel, wobei der Haltevorsprung an dem ersten Schenkel angeordnet ist. Durch die vorteilhafte Ausbildung wird eine einfache Betätigung des Koppelelementes zum Lösen der Arretierung gewährleistet. Indem ein Benutzer auf den zweiten Schenkel, beispielsweise an dessen äußeren Ende, in Richtung des Maskenkörpers eine Kraft ausübt, also auf den zweiten Schenkel drückt, so wird der Haltevorsprung von dem Filtermodul weggezogen und in seine freigebende Position verlagert. Besonders bevorzugt ist der Haltevorsprung dazu an dem von dem Maskenkörper wegweisenden Ende des ersten Schenkels angeordnet, um durch das Betätigen des zweiten Schen kel eine größtmögliche Verlagerung des Haltevorsprungs bei nur geringer Kraftaufwendung zu erreichen.Furthermore, it is preferably provided that the coupling element is L-shaped, with a first leg attached to the mask body and with a second leg facing away from the filter module, wherein the retaining projection is arranged on the first leg. The advantageous embodiment ensures a simple operation of the coupling element for releasing the locking. By a user on the second leg, for example, at its outer end, in the direction of the mask body exerts a force, so presses on the second leg, the retaining projection is pulled away from the filter module and moved to its releasing position. For this purpose, the retaining projection is particularly preferably arranged on the end of the first leg facing away from the mask body, in order to prevent the second leg from being pushed by the second leg kel to achieve the greatest possible displacement of the retaining projection with only a small amount of force.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist außerdem vorgesehen, dass der zweite Schenkel Mittel zur Befestigung des Kopfbefestigungsbandes aufweist. Bei diesen Mitteln handelt es sich bevorzugt um Klemmmittel, mittels derer das Befestigungsband an dem Koppelelement beziehungsweise am zweiten Schenkel des Koppelelementes festklemmbar ist. Die Klemmmittel umfassen bevorzugt einen auf den zweiten Schenkel aufschiebbaren elastisch verformbaren Ring, sowie eine in dem zweiten Schenkel ausgebildete Struktur, die mindestens eine, vorzugsweise mehrere Vertiefungen in dem zweiten Schenkel aufweist, so dass das Kopfbefestigungsband durch Aufschieben des Ringes auf das Kopfbefestigungsband und das Koppelelement in die Vertiefung(en) gedrängt und dadurch eine hohe Haltekraft des Kopfbefestigungsbandes an dem Koppelelement gewährleistet wird.According to a preferred embodiment of the invention, it is also provided that the second leg has means for fixing the head attachment band. These means are preferably clamping means by means of which the fastening band can be clamped to the coupling element or to the second leg of the coupling element. The clamping means preferably comprise an elastically deformable ring which can be pushed onto the second limb and a structure formed in the second limb which has at least one, preferably a plurality of depressions in the second limb so that the head fastening band can be pushed onto the head fastening band and the coupling element by sliding the ring on pushed into the recess (s), thereby ensuring a high holding force of the head attachment band to the coupling element.

Weiterhin ist bevorzugt vorgesehen, dass dem Filtermodul beziehungsweise dem jeweiligen Filtermodul eines oder mehrere der erfindungsgemäßen Koppelelemente zugeordnet sind. So ist es gemäß einer ersten Ausführungsform vorgesehen, dass das Filtermodul insgesamt allein durch mehrere über den Umfang des Filtermoduls verteilt angeordnete erfindungsgemäße Koppelelemente an dem Maskenkörper gehalten ist.Furthermore, it is preferably provided that one or more of the coupling elements according to the invention are assigned to the filter module or the respective filter module. Thus, according to a first embodiment, it is provided that the filter module is held on the mask body as a whole by a plurality of coupling elements according to the invention that are distributed over the circumference of the filter module.

Gemäß einer erfindungsgemäßen zweiten Ausführungsform ist vorgesehen, dass dem Filtermodul nur an einer Seite ein oder mehrere Koppelelemente, wie sie oben stehend beschrieben wurden, zugeordnet sind, und dass das Filtermodul an einer der ersten Seite gegenüberliegenden zweiten Seite wenigstens einen Arretiervorsprung aufweist, der in eine Arretieraufnahme des Maskenkörpers einschiebbar/eingeschoben ist. Der Arretiervorsprung steht zweckmäßigerweise seitlich von dem Filtermodul vor, so dass er durch eine seitliche Schiebebewegung des Filtermoduls in die Arretieraussparung einschiebbar ist. Die Arretieraussparung und der Arretiervorsprung sind dabei vorzugsweise derart ausgebildet, dass das Filtermodul mit in der Arretieraussparung befindlichem Arretiervorsprung verkippbar ist. Dadurch lässt sich das Filtermodul durch ein verkipptes Einsetzen mit dem Arretiervorsprung in die Arretieraufnahme und einem anschließenden Herabsenken seiner von dem Maskenkörper abstehenden Seite in seine Gebrauchsposition einbringen, wenn der oder die Haltevorsprünge sich in ihrer freigebenden Position befinden. Zweckmäßigerweise ist hierbei vorgesehen, dass wie zuvor beschrieben, die Haltevorsprünge als Rastnasen ausgebildet sind, so dass das Filtermodul zunächst verkippt in die Arretieraufnahme mit dem Arretiervorsprung einsetzbar und durch ein anschließendes Absetzen auf den Maskenkörper in seine Gebrauchsposition einklickbar ist, wobei die Koppelelemente automatisch mit den Haltevorsprüngen in die freigebende und anschließend in die arretierende Position aufgrund der Federkraft beziehungsweise Eigenelastizität und der Ausbildung als Rastnase verlagert werden.According to a second embodiment of the invention it is provided that the filter module only one side or more coupling elements, as described above, are assigned, and that the filter module to one of first side opposite second side has at least one locking projection which is inserted / inserted into a locking receptacle of the mask body. The locking projection is expediently in front of the filter module, so that it can be pushed into the locking recess by a lateral sliding movement of the filter module. The locking recess and the locking projection are preferably designed such that the filter module is tiltable with befindlichem in the locking recess locking projection. As a result, the filter module can be brought into its use position by a tilted insertion with the locking projection into the locking receptacle and a subsequent lowering of its projecting from the mask body side in its use position when the holding projections or are in their releasing position. Conveniently, it is provided that, as described above, the holding projections are designed as latching lugs, so that the filter module is first tilted inserted into the locking receptacle with the locking projection and einklickbar by a subsequent settling on the mask body in its use position, wherein the coupling elements automatically with the retaining projections in the releasing and then in the arresting position be relocated due to the spring force or inherent elasticity and training as a latch.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist außerdem vorgesehen, dass an dem Maskenkörper wenigstens ein weiterer dem Filtermodul zugeordneter und zumindest bereichsweise elastisch verlagerbarer Rastvorsprung, insbesondere in Form einer Rastnase, zugeordnet ist. Der weite Rastvorsprung unterscheidet sich von dem zuvor beschrieben Koppelelement insbesondere darin, dass es keine Mittel oder Möglichkeit zur Befestigung des Kopfbefestigungsbandes aufweist. Der mindestens eine zusätzliche Rastvorsprung dient allein zur Arretierung des Filtermoduls an dem Maskenkörper und unterstützt dadurch die Wirkung des einen oder der mehreren erfindungsgemäßen Koppelelemente.According to an advantageous development of the invention it is also provided that at least one further filter element associated with the filter module and at least partially elastically displaceable latching projection, in particular in the form of a latching nose assigned. The wide latching projection differs from the coupling element described above in particular in that it has no means or possibility for fastening the head-mounting strap. The at least one additional latching projection alone serves to lock the filter module to the mask body and thereby supports the action of the one or more coupling elements according to the invention.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass das Filtermodul und/oder die Aufnahmevertiefung beziehungsweise der Maskenkörper jeweils wenigstens einen beabstandet zu dem Einlassventil rahmenartig verlaufenden Dichtsteg aufweisen. Durch den rahmenartigen Verlauf ist der Dichtsteg durchgehend, also ohne Unterbrechung, ausgebildet und umgibt das Einlassventil, zumindest wenn das Filtermodul in die jeweilige Aufnahmevertiefung eingesetzt ist. Der Dichtsteg ist dabei derart ausgebildet, dass er im eingesetzten Zustand des Filtermoduls dichtend an dem Filtermodul beziehungsweise dessen Filtermodulboden und/oder an dem Boden der Aufnahmevertiefung aufliegt. Besonders bevorzugt ist der Dichtsteg dazu zumindest bereichsweise elastisch verformbar ausgebildet. Dadurch stellt der Dichtsteg außerdem auch eine Federkraft bereit, die zum sicheren Arretieren des Filtermoduls mittels der Koppelelemente nutzbar ist.According to a preferred embodiment of the invention it is provided that the filter module and / or the receiving recess or the mask body each have at least one spaced apart from the inlet valve to the inlet valve extending sealing ridge. Due to the frame-like course of the sealing bar is continuous, so without interruption, formed and surrounds the inlet valve, at least when the filter module is inserted into the respective receiving recess. The sealing ridge is designed such that it sealingly in the inserted state of the filter module the filter module or its filter module bottom and / or rests on the bottom of the receiving recess. Particularly preferably, the sealing web is at least partially formed elastically deformable. As a result, the sealing web also provides a spring force which can be used to securely lock the filter module by means of the coupling elements.

Der Dichtsteg erstreckt sich dabei vorzugsweise parallel zur Außenkontur der jeweiligen Aufnahmevertiefung. Alternativ kann der Dichtsteg auch eine von der Außenkontur unabhängige beziehungsweise abweichende Form aufweisen. Beispielsweise kann der Dichtsteg sich kreisringförmig um das Einlassventil erstrecken. Insbesondere kann dabei vorgesehen sein, dass der Dichtsteg stets beabstandet zu den Seitenwänden der jeweiligen Aufnahmevertiefung angeordnet ist. Auch ist es denkbar, dass die Ringform des Dichtstegs nicht kreisförmig, sondern beispielsweise mehreckförmig, beispielsweise quadratisch oder rechteckförmig oder auch sternförmig ausgebildet ist.The sealing ridge preferably extends parallel to the outer contour of the respective receiving recess. Alternatively, the sealing web may also have a shape that is independent of or deviating from the outer contour. For example, the sealing web may extend in a circular ring around the inlet valve. In particular, it may be provided that the sealing web is always arranged spaced from the side walls of the respective receiving recess. It is also conceivable that the annular shape of the sealing web is not circular, but for example, polygonal, for example, square or rectangular or star-shaped.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass der Maskenkörper mehrteilig ausgebildet ist, mit einem Maskengrundkörper und mit mindestens einem die jeweilige Aufnahmevertiefung bildenden Schalenelement, wobei das Schalenelement bevorzugt eine höhere Steifigkeit aufweist als der Maskengrundkörper. Durch die mehrteilige Ausbildung wird die Fertigung des Maskenkörpers vereinfacht. Darüber hinaus lässt sich durch die mehrteilige Ausbildung erreichen, dass der Maskengrundkörper und das Schalenelement unterschiedliche Eigenschaften insbesondere in Bezug auf ihre Flexibilität aufweisen. Durch die bevorzugte Ausführungsform, gemäß welcher der Maskengrundkörper eine höhere Flexibilität als das Schalenelement aufweist, wird gewährleistet, dass sich der Maskengrundkörper einerseits angenehm an die Gesichtsform des Benutzers anpasst, und dass das Schalenelement eine ausreichend hohe Steifigkeit zur sicheren und dichten Verbindung des Filtermoduls mit dem Maskenkörper gewährleistet.According to a preferred embodiment of the invention, it is provided that the mask body is designed in several parts, with a mask base body and with at least one shell element forming the respective receiving recess, the shell element preferably having a higher rigidity than the mask main body. Due to the multi-part design, the production of the mask body is simplified. In addition, can be achieved by the multi-part design that the mask body and the shell element have different properties, especially in terms of their flexibility. By the preferred embodiment, according to which the mask main body has a higher flexibility As the shell element, it is ensured that the mask base body on the one hand agrees pleasantly to the face shape of the user, and that the shell element ensures a sufficiently high rigidity for secure and tight connection of the filter module with the mask body.

Im Folgenden soll die Erfindung anhand der Zeichnung näher erläutert werden. Dazu zeigen:

a respirator with filter modules in a perspective view,
FIG. 2
the respirator in a top view without filter modules,
FIG. 3

Figur 1 zeigt in einer perspektivischen Darstellung eine Atemschutzmaske 1, die einen Maskenkörper 2 aufweist, der dazu ausgebildet ist, die Nase und den Mund eines Benutzers von der Umgebung zu trennen. Dazu weist der Maskenkörper 2 dem Benutzer zugewandt eine flexible Dichtlippe 3 auf, die sich an die Gesichtsform des Benutzers gasdicht anpasst, wenn die Atemschutzmaske 1 gegen das Gesicht des Benutzers gedrückt wird. An dem Maskenkörper 2 sind dazu mehrere, vorliegend vier Koppelelemente 4 angeordnet, die Mittel 5 zur Befestigung eines insbesondere flexiblen Kopfbefestigungsbandes 7 aufweisen. Die Mittel 5 sind dabei an einem freien pinnförmigen Ende des jeweiligen Koppelelementes 4 als mehrere sich quer zur Längserstreckung des Koppelelementes 4 erstreckende Vertiefungen 6 ausgebildet. Zur Befestigung des Kopfbefestigungsbandes 7 wird ein freies Ende des Kopfbefestigungsbandes 7 seitlich an das Koppelelement 4 im Bereich der Mittel 5 angelegt. Ein elastisch verformbarer Ring 8 wird dann auf das Koppelelement 4 und das Kopfbefestigungsband 7 aufgeschoben, um letzteres an dem Koppelelement 4 im Bereich der Vertiefungen 6 an diesem festzuklemmen. Die Vertiefungen 6 dienen dabei insbesondere zur formschlüssigen Arretierung des Kopfbefestigungsbands 7 an dem jeweiligen Koppelelement 4. Wie in Figur 1 gezeigt, kann das Kopfbefestigungsband 7 auch mehrere freie Enden aufweisen, von denen jeweils eines einem der Koppelelemente 4 zugeordnet ist. Alternativ können auch mehrere Kopfbefestigungsbänder 7 vorgesehen sein. Üblich weisen das oder die Kopfbefestigungsbänder 7 eine Möglichkeit zur Längenanpassung auf, so dass durch entsprechende Einstellung der Länge der Maskenkörper 2 optimal gegen das Gesicht des Benutzers gezogen wird, um die gasdichte Verbindung mittels der Dichtlippe 3 zu realisieren. FIG. 1 shows in a perspective view of a respirator 1, which has a mask body 2, which is adapted to separate the nose and the mouth of a user from the environment. For this purpose, the mask body 2 facing the user has a flexible sealing lip 3, which adapts to the face shape of the user gas-tight when the respirator 1 is pressed against the face of the user. For this purpose, a plurality of, in the present case, four coupling elements 4 are arranged on the mask body 2 and have means 5 for fastening a particularly flexible head fastening strip 7. The means 5 are at a free pinnförmigen end of the respective coupling element 4 as a plurality of transversely to the longitudinal extent of the coupling element 4 extending recesses 6 are formed. For attachment of the head attachment band 7, a free end of the head attachment band 7 is applied laterally to the coupling element 4 in the region of the means 5. An elastically deformable ring 8 is then pushed onto the coupling element 4 and the head mounting band 7, to clamp the latter to the coupling element 4 in the region of the recesses 6 at this. The recesses 6 serve in particular for the positive locking of the head mounting band 7 on the respective coupling element 4. As in FIG. 1 shown, the head mounting band 7 may also have a plurality of free ends, one of which is associated with one of the coupling elements 4 each. Alternatively, a plurality of head attachment straps 7 may be provided. Usually, the one or more head attachment straps 7 have a possibility for length adjustment, so that by appropriate adjustment of the length of the mask body 2 is optimally pulled against the face of the user to realize the gas-tight connection by means of the sealing lip 3.

An dem Maskenkörper 2 ist weiterhin ein Ausatemventil 9 angeordnet, das den Maskenkörper 2 durchdringt. Vorliegend ist das Ausatemventil 9 durch ein manuell betätigbares Testventil 10 zum Test der Gasdichtheit der Atemschutzmaske 1 verdeckt. Das Ausatemventil 9 ist - wie üblich - dazu ausgebildet, Luft aus dem Innenraum beziehungsweise aus dem zwischen Maskenkörper 2 und Gesicht gebildeten Gasraum nach außen entweichen zu lassen, während es in entgegengesetzter Strömungsrichtung schließt, so dass der Benutzer nicht ungefilterte Luft aus der Umgebung durch das Ausatemventil 9 einatmen kann. Das Ausatemventil weist dazu ein verlagerbares oder elastisch verformbares Rückschlagventilelement auf.On the mask body 2, an exhalation valve 9 is further arranged, which penetrates the mask body 2. In the present case, the exhalation valve 9 is covered by a manually operable test valve 10 for testing the gas-tightness of the respiratory mask 1. The exhalation valve 9 is - as usual - designed to let escape air from the interior or from the gas space formed between the mask body 2 and face to the outside, while it closes in the opposite direction of flow, so that the user unfiltered air from the environment through the exhalation valve 9 inhale. The exhalation valve has for this purpose a displaceable or elastically deformable check valve element.

Um Umgebungsluft in den Gasraum einzulassen, sind vorliegend zwei Einatemventile 11 vorgesehen, die unterhalb des Ausatemventils 9 und beidseits zu dem Atemvenil 9 an dem Maskenkörper 2 angeordnet sind. Den Einatemventilen 11 ist jeweils ein Filtermodul 12 zugeordnet, das auf der Außenseite des Maskenkörpers 2 anordenbar beziehungsweise angeordnet ist, wie in Figur 1 gezeigt.In order to admit ambient air into the gas space, two inhalation valves 11 are presently provided, which are arranged below the exhalation valve 9 and on both sides to the Atemvenil 9 on the mask body 2. The inhalation valves 11 are each assigned a filter module 12 which can be arranged or arranged on the outside of the mask body 2, as in FIG FIG. 1 shown.

Figur 2 zeigt die Atemschutzmaske 1 in einer Draufsicht ohne die Filtermodule 12. Der Maskenkörper 2 weist zwei Aufnahmevertiefungen 13 auf, deren Außenkontur im Wesentlichen der Kontur der Filtermodule 12 entspricht, so dass diese zumindest im Wesentlichen passgenau in die jeweilige Aufnahmevertiefung 13 einsetzbar sind. Die jeweilige Aufnahmevertiefung 13 weist einen Boden 14 auf, in welchem eine Öffnung 15 ausgebildet ist. Der jeweilige Boden 14 ist dabei in mehreren Richtungen gekrümmt ausgebildet, um einen vorteilhaften Tragekomfort sowie eine optisch vorteilhafte Gestaltung der Atemschutzmaske 1 zu erreichen. Der jeweiligen Öffnung 15 ist dabei das jeweilige Einatemventil 11 zugeordnet. Dieses wird durch ein flexibles Ventilelement 16 gebildet, das im Normalzustand die Öffnung 15 dichtend verschließt. Das Ventilelement 16 ist auf der Rückseite des Maskenkörpers 2, also in dem Gasraum liegend angeordnet und liegt somit an der Rückseite des Maskenkörpers 2 die jeweilige Öffnung 15 überdeckend an. Die jeweilige Öffnung 15 weist dabei eine sich über ihren Querschnitt erstreckende Gitterstruktur 17 auf, an welcher mittig das jeweilige Ventilelement 16 gehalten ist. Die Ventilelemente 16 sind dabei kreisscheibenförmig ausgebildet und nur mittig an der Gitterstruktur 17 gehalten. Wenn der Benutzer einatmet und in dem Gasraum des Maskenkörpers 2 ein Unterdruck entsteht, wird das jeweilige Ventilelement 16 nach innen in den Gasraum hinein verformt, wodurch die jeweilige Öffnung 15 freigegeben und der Benutzer die durch das jeweilige Filtermodul 12 gefilterte Luft einatmen kann. Atmet der Benutzer aus, so werden die Ventilelemente 16 die jeweilige Öffnung verschließend gegen den Maskenkörper 2 gedrängt. FIG. 2 shows the respirator 1 in a plan view without the filter modules 12. The mask body 2 has two receiving recesses 13 whose outer contour substantially corresponds to the contour of the filter modules 12, so that they are at least substantially accurately fit into the respective receiving recess 13 can be used. The respective receiving recess 13 has a bottom 14 in which an opening 15 is formed. The respective bottom 14 is curved in several directions in order to achieve an advantageous wearing comfort and an optically advantageous design of the respirator 1. The respective opening 15 is associated with the respective inhalation valve 11. This is formed by a flexible valve element 16 which closes the opening 15 in the normal state sealing. The valve element 16 is arranged on the rear side of the mask body 2, that is, lying in the gas space, and thus lies on the back of the mask body 2, the respective opening 15 overlapping. The respective opening 15 in this case has a grid structure 17 extending over its cross section, on which the respective valve element 16 is centrally held. The valve elements 16 are circular disk-shaped and held only centrally on the lattice structure 17. If the user inhales and creates a negative pressure in the gas space of the mask body 2, the respective valve member 16 is deformed inwardly into the gas space, whereby the respective opening 15 released and the user can inhale the filtered through the respective filter module 12 air. Exhales the user, the valve elements 16, the respective opening closing against the mask body 2 urged.

Die jeweilige Aufnahmevertiefung 13 wird durch einen zumindest im Wesentlichen durchgehenden Rand 18 begrenzt, der sich in einer von einem Kreis abweichenden Kontur um das jeweilige Einatemventil 11 herum und beabstandet dazu erstreckt. Die Kontur entspricht dabei vorliegend im Wesentlichen der eines Rechtecks mit gerundeten Ecken. Die jeweilige Aufnahmevertiefung 13 weist somit im Wesentlichen vier Seitenwandabschnitte auf, von denen sich jeweils zwei einander gegenüberliegen. Weiterhin ist vorgesehen, dass sich in der jeweiligen Aufnahmevertiefung 13 parallel zu dem jeweiligen Rand 18 auf dem Boden 14 jeweils ein umlaufender Dichtsteg 19 erstreckt, der insbesondere elastisch verformbar ausgebildet ist. Wird das jeweilige Filtermodul in die entsprechende Aufnahmevertiefung 13 eingebracht, so liegt es mit einer Unterseite dichtend an dem jeweiligen Dichtsteg 19 an, so dass ein abgedichteter Luftraum zwischen den Filtermodulen 12 und dem jeweiligen Einlassventil 11 zur Verfügung gestellt wird, der gewährleistet, dass nur durch das jeweilige Filtermodul 12 gefilterte Luft in das Einatemventil 11 gelangt.The respective receiving recess 13 is bounded by an at least substantially continuous edge 18, which extends in a circle deviating from a circle around the respective inhalation valve 11 and spaced therefrom. The contour here essentially corresponds to that of a rectangle with rounded corners. The respective receiving recess 13 thus has essentially four side wall sections, two of which are opposite each other. Furthermore, it is provided that extends in the respective receiving recess 13 parallel to the respective edge 18 on the bottom 14 each have a circumferential sealing web 19, which is in particular formed elastically deformable. If the respective filter module is introduced into the corresponding receiving recess 13, it rests with a bottom sealingly against the respective sealing web 19, so that a sealed air space between the filter modules 12 and the respective inlet valve 11 is provided, which ensures that only by the respective filter module 12 passes filtered air into the inhalation valve 11.

Die Filtermodule 12 sind lösbar an dem Maskenkörper 2 gehalten, so dass sie beispielsweise bei nachlassender Wirkung oder mit steigender Verunreinigung ausgewechselt werden können. Eine dazu vorgesehene lösbare Arretierung der Filtermodule 12 soll im Folgenden beschrieben werden.The filter modules 12 are releasably held on the mask body 2, so that they can be replaced, for example, with decreasing effect or with increasing contamination. One for this provided releasable locking of the filter modules 12 will be described below.

Figur 3 zeigt in einer vereinfachten Schnittdarstellung der Atemschutzmaske 1 einen Längsschnitt durch eine der Aufnahmevertiefungen 13 mit einem darin angeordneten Filtermodul 12, wobei von dem Filtermodul 12 vorliegend nur die Außenkontur gezeigt ist. Das Filtermodul 12 weist zweckmäßigerweise ein Filtermodulgehäuse 20 auf, welches dem Filtermodul 12 die entsprechende Kontur gibt. Das Filtermodul 12 weist eine dem Rand 18 entsprechende Außenkontur auf, die ebenfalls von einem Kreis abweicht und im Wesentlichen rechteckförmig mit abgerundeten Ecken ausgebildet ist, so dass auch das Filtermodul 12 jeweils zwei einander gegenüberliegende Seiten aufweist. An einer Seite 21 weist das Filtermodul 12 einen Arretiervorsprung 22 auf, der seitlich von dem Filtermodul 12 vorsteht. Der Arretiervorsprung 22 liegt in einer Arretieraufnahme 23 ein, die in dem Rand 18 der Aufnahmevertiefung 13 ausgebildet ist. Der Vorsprung 22 ist in die Arretieraufnahme 23 eingeschoben, so dass das Filtermodul 12 an der Seite 21 formschlüssig in der Aufnahmevertiefung 13 gehalten ist. FIG. 3 shows in a simplified sectional view of the respirator 1 a longitudinal section through one of the receiving recesses 13 with a filter module 12 disposed therein, wherein of the filter module 12 in the present case, only the outer contour is shown. The filter module 12 expediently has a filter module housing 20, which gives the filter module 12 the corresponding contour. The filter module 12 has an outer contour corresponding to the edge 18, which also deviates from a circle and is substantially rectangular in shape with rounded corners, so that the filter module 12 also has two mutually opposite sides. On one side 21, the filter module 12 has a locking projection 22 which projects laterally from the filter module 12. The locking projection 22 is located in a locking receptacle 23 which is formed in the edge 18 of the receiving recess 13. The projection 22 is inserted into the locking receptacle 23, so that the filter module 12 is held on the side 21 in a form-fitting manner in the receiving recess 13.

Der der Seite 21 gegenüberliegenden Seite 24 weist das Filtermodulgehäuse 20 jeweils einem der Koppelelemente 4 zugeordnet eine Vertiefung 25 auf. Die Koppelelemente 4 sind, wie im Wesentlichen aus Figuren 2 bis 4 ersichtlich, L-förmig ausgebildet mit einem ersten Schenkel 26, der mit dem Maskenkörper 2 verbunden ist, sowie mit einem zweiten Schenkel 27, der vorliegend in einem rechten Winkel zu dem ersten Schenkel 26 und von dem Filtermodul 12 beziehungsweise von der Aufnahmevertiefung 13 wegweisend ausgerichtet ist. An dem zweiten Schenkel 27 sind die zuvor bereits erwähnten Mittel 5 zur Befestigung des Kopfbefestigungsbandes 7 vorgesehen. Der Schenkel 26 ist zweckmäßigerweise einstückig mit dem Maskenkörper 2 oder mit einem die Aufnahmevertiefung 13 insgesamt bildenden Maskenkörperelement des dann mehrteilig ausgebildeten Maskenkörpers 2 ausgebildet. An dem dem Maskenkörper 2 gegenüberliegenden Ende des ersten Schenkels 26, also in dem Bereich, in welchem sich der erste Schenkel und der zweite Schenkel 27 treffen, weist der erste Schenkel 26 eine Rastnase 28 auf, die in Richtung der Aufnahmevertiefung 13 seitlich vorsteht. Die Rastnase 28 weist einen im Wesentlichen flachen und dem Maskenboden 2 zugewandten Anschlag 29 sowie eine von dem Maskenkörper 2 abgewandte Einführschräge 30 auf.The side 21 opposite side 24, the filter module housing 20 each one of the coupling elements 4 associated with a recess 25. The coupling elements 4 are, as essentially made FIGS. 2 to 4 can be seen, L-shaped with a first leg 26 which is connected to the mask body 2, and with a second leg 27, which in the present case at a right angle to the first leg 26 and the filter module 12 and the receiving recess 13 pointing away is. On the second leg 27 are those already mentioned above Means 5 for attachment of the head mounting band 7 is provided. The leg 26 is expediently formed integrally with the mask body 2 or with a receiving body 13 forming the overall mask body member of the then multi-part mask body 2. At the end of the first leg 26 opposite the mask body 2, that is to say in the region in which the first leg and the second leg 27 meet, the first leg 26 has a latching nose 28 which protrudes laterally in the direction of the receiving recess 13. The detent 28 has a substantially flat and the mask base 2 facing stop 29 and a facing away from the mask body 2 insertion 30.

In dem in Figur 3 dargestellten Zustand liegt die Rastnase 28 bereichsweise in der Vertiefung 25 des Filtermoduls 12 ein, so dass dieses auf der Seite 24 ebenfalls an dem Maskenkörper 2 durch die einen Haltevorsprung 31 bildende Rastnase 28 gehalten ist. Der Abstand des Haltevorsprungs 31 von dem Boden 14 der Aufnahmevertiefung 13 ist dabei derart gewählt, dass im arretierten Zustand das Filtermodul 12 dichtend auf dem Dichtsteg 19 aufliegt. Entsprechend sind die Arretieraufnahme 23 und der Arretiervorsprung 22 ausgebildet. Zweckmäßigerweise sind die Abstände dabei derart gewählt, dass der Dichtsteg 19 in der arretierten Position des Filtermoduls 12 elastisch verformt ist, so dass eine Federspannung auf den Haltevorsprung 31 sowie den Arretiervorsprung 22 wirkt, um eine Selbsthemmung der Arretierung zu erreichen. Zusätzlich kann gemäß einem hier nicht dargestellten Ausführungsbeispiel vorgesehen sein, dass die Rastnase 28 einen zu dem Maskenkörper 2 weisenden Vorsprung aufweist, der das Filtermodulgehäuse 20 hintergreift, um ein versehentliches Lösen der Arretierung sicher zu vermeiden.In the in FIG. 3 shown state, the locking lug 28 is partially in the recess 25 of the filter module 12, so that it is also held on the side 24 on the mask body 2 by the retaining projection 31 forming locking lug 28. The distance of the holding projection 31 from the bottom 14 of the receiving recess 13 is selected such that in the locked state, the filter module 12 sealingly rests on the sealing web 19. Accordingly, the locking receptacle 23 and the locking projection 22 are formed. Conveniently, the distances are chosen such that the sealing web 19 is elastically deformed in the locked position of the filter module 12, so that a spring tension on the retaining projection 31 and the locking projection 22 acts to achieve a self-locking of the lock. In addition, according to an embodiment not shown here, it may be provided that the latching nose 28 has a projection pointing towards the mask body 2, which engages behind the filter module housing 20 in order to reliably avoid accidental release of the lock.

Um das Filtermodul 12 von dem Maskenkörper 2 zu lösen, ist der Haltevorsprung 31 aus der Vertiefung 25 herauszuziehen. Durch die vorteilhafte Ausbildung der vorliegenden Atemschutzmaske 1 kann dies einfach dadurch erreicht werden, dass auf das freie Ende des zweiten Schenkels 27 gemäß Pfeil 32 gedrückt wird, wodurch der elastisch verformbare Schenkel 26 verbogen und der Haltevorsprung 31 aus der Vertiefung 25 herausgezogen wird, wie durch einen Pfeil 33 angedeutet.In order to detach the filter module 12 from the mask body 2, the retaining projection 31 is to be pulled out of the recess 25. Due to the advantageous embodiment of the present respirator 1 this can be achieved simply by pressing on the free end of the second leg 27 according to arrow 32, whereby the elastically deformable leg 26 is bent and the retaining projection 31 is pulled out of the recess 25, as by an arrow 33 indicated.

Figur 4 zeigt hierzu die Atemschutzmaske 1 in der Längsschnittdarstellung gemäß Figur 3, wobei das Filtermodul 12 von dem betätigten Koppelement 4 beziehungsweise von den betätigten Koppelelementen 4 gelöst ist. Sobald der jeweilige Haltevorsprung 31 aus der Vertiefung 25 entfernt wurde, wie in Figur 4 gezeigt, kann das Filtermodul 12 durch ein Ankippen an der Seite 24 nach oben beziehungsweise von der Aufnahmevertiefung 13 weg gezogen werden, indem das Filtermodul 12 zunächst an der Seite 24 angehoben wird, wie durch einen Pfeil 34 angedeutet, und anschließend mit dem Arretiervorsprung 22 aus der Arretieraufnahme 23 herausgezogen werden, wie durch einen Pfeil 35 angedeutet. Die Arretieraufnahme 23 und der Arretiervorsprung 22 sind dabei derart ausgebildet, beziehungsweise mit derart viel Spiel versehen, dass das Filtermodul 12 mit dem Haltevorsprung 22 in der Arretieraufnahme 23 verkippbar ist. FIG. 4 shows the respirator 1 in the longitudinal sectional view according to FIG. 3 , wherein the filter module 12 is released from the actuated coupling element 4 or from the actuated coupling elements 4. Once the respective retaining projection 31 has been removed from the recess 25, as in FIG. 4 11, the filter module 12 can be pulled upward by a tilting on the side 24 or away from the receiving recess 13 by first lifting the filter module 12 on the side 24, as indicated by an arrow 34, and then with the locking projection 22 the locking receptacle 23 are pulled out, as indicated by an arrow 35. The locking receptacle 23 and the locking projection 22 are designed in this case, or provided with so much play that the filter module 12 with the retaining projection 22 in the locking receptacle 23 is tilted.

Zum Einsetzen des Filtermoduls 12 in die jeweilige Aufnahmevertiefung 13 wird dieses zunächst mit dem Arretiervorsprung 22 in die Arretieraufnahme 23 eingeschoben und anschließend wird die Seite 24 in die Arretieraufnahme 13 eingedrückt. Durch die vorteilhafte Ausbildung des Haltevorsprungs 31 als Rastnase 28 mit der Einführschräge 30 wird dabei erreicht, dass der jeweilige Haltevorsprung 31 beim Eindrücken automatisch zur Seite in eine freigebende Position, wie in Figur 4 gezeigt, verlagert wird. Sobald das Filtermodul 12 auf dem Dichtsteg 19 aufliegt, rastet der Haltevorsprung 31 in die Vertiefung 25 aufgrund der Eigenelastizität des Koppelelementes 4 ein und arretiert das Filtermodul 12 in seiner Gebrauchsstellung.To insert the filter module 12 in the respective receiving recess 13, this is first inserted with the locking projection 22 in the locking receptacle 23 and then the side 24 is pressed into the locking receptacle 13. Due to the advantageous embodiment of the retaining projection 31 as a latching nose 28 with the insertion 30 is thereby achieved that the respective retaining projection 31 when pressed automatically to the side in a releasing position, as in FIG. 4 shown, relocated. As soon as the filter module 12 rests on the sealing web 19, the retaining projection 31 engages in the recess 25 due to the inherent elasticity of the coupling element 4 and locks the filter module 12 in its position of use.

Wie insbesondere aus Figur 2 ersichtlich, sind vorliegend zwei Koppelelemente 4 auf der der Arretieraufnahme 23 gegenüberliegenden Seite der jeweiligen Aufnahmevertiefung 13 angeordnet. Alternativ können auch nur ein entsprechendes Koppelelement 4 oder mehr als zwei Koppelelemente 4 pro Filtermodul 12 vorgesehen sein. Optional ist weiterhin vorgesehen, dass zwischen den beiden vorliegenden Koppelelementen 4 jeweils ein zusätzlicher Rastvorsprung 36 vorgesehen ist, der bis auf das Vorsehen der Mittel 5 in seinem Aufbau und seiner Struktur im Wesentlichen den Koppelelementen 4 entspricht. Die Rastvorsprünge 36 rasten ebenfalls in entsprechenden Vertiefungen des jeweiligen Filtermoduls 11 mit einem entsprechend als Rastnase 28' ausgebildeten Haltevorsprung 31' ein und können durch elastische Verformung außer Eingriff gebracht werden. Auch ist es denkbar, die jeweilige Arretieraufnahme 23 statt durch eine Vertiefung in dem Rand 18 durch jeweils einen in die jeweilige Aufnahmevertiefung 13 hineinragenden Vorsprung 37 des Randes 18, wie in Figur 2 gezeigt, zu bilden.As in particular from FIG. 2 can be seen, in the present case two coupling elements 4 are arranged on the locking receptacle 23 opposite side of the respective receiving recess 13. Alternatively, only one corresponding coupling element 4 or more than two coupling elements 4 per filter module 12 may be provided. Optionally, it is further provided that between the two coupling elements 4 present in each case an additional latching projection 36 is provided which corresponds to the provision of the means 5 in its structure and its structure substantially the coupling elements 4. The latching projections 36 also snap into corresponding recesses of the respective filter module 11 with a correspondingly designed as a latching nose 28 'retaining projection 31' and can be brought out of engagement by elastic deformation. It is also conceivable that the respective locking receptacle 23 instead of by a depression in the edge 18 by each projecting into the respective receiving recess 13 projection 37 of the rim 18, as in FIG. 2 shown to form.

Insgesamt wird dadurch erreicht, dass die Filtermodule 12 auf einfache Art und Weise an dem Maskenkörper 2 durch ein Einklicken beziehungsweise Einrasten in der jeweiligen Aufnahmevertiefung 13 arretiert werden können. Gleichzeitig lässt sich die Arretierung auf einfache Art und Weise durch Betätigen der Koppelelemente 4 und gegebenenfalls der Rastvorsprünge 36 wieder lösen.Overall, it is achieved that the filter modules 12 can be locked in a simple manner to the mask body 2 by clicking or snapping into the respective receiving recess 13. At the same time, the lock can be opened simple manner by pressing the coupling elements 4 and optionally the locking projections 36 solve again.

Gemäß dem vorliegenden Ausführungsbeispiel ist außerdem vorgesehen, dass der Maskenkörper 2 mehrteilig ausgebildet ist und dazu einen Maskengrundkörper 38 sowie zwei Schalenelemente 39 aufweist, die jeweils eine der Aufnahmevertiefungen 13 bilden. Die Schalenelemente 39 weisen dabei eine höhere Steifigkeit auf als der Maskengrundkörper 38. Hierdurch wird gewährleistet, dass sich der Maskengrundkörper 38 einerseits vorteilhaft an die Gesichtsform eines Benutzers anpasst, und dass andererseits die Aufnahmevertiefungen (13) ausreichend steif ausgebildet sind, um einen sicheren Halt des jeweiligen Filtermoduls (12) zu gewährleisten.According to the present exemplary embodiment, provision is also made for the mask body 2 to be designed in several parts and for this purpose to have a mask main body 38 and two shell elements 39, which each form one of the receiving recesses 13. The shell elements 39 in this case have a higher rigidity than the mask main body 38. This ensures that the mask body 38 on the one hand advantageously adapts to the face shape of a user, and that on the other hand, the receiving recesses (13) are sufficiently rigid to ensure a secure fit of the to ensure respective filter module (12).
