Description

Die Erfindung betrifft eine Anordnung zur lösbaren Verbindung einer Atemschutzmaske mit einem Schutzhelm mittels einer beidseitig angebrachten lösbaren und längenveränderlichen Halterung.The invention relates to an arrangement for detachable connection of a respirator with a protective helmet by means of a both sides mounted detachable and variable-length bracket.

Aus DE 103 14 136 B3 ist eine Haltevorrichtung für Atemschutzmasken, die nicht mittels einer Bänderung unmittelbar am Kopf des Benutzers gehalten sind, sondern über eine spezielle Halterung direkt mit dem vom Benutzer auf dem Kopf getragenen Schutzhelm verbunden und von diesem wieder gelöst werden können, sind bekannt. Die lösbare Befestigung der Atemschutzmaske unmittelbar am Schutzhelm gewährleistet ein schnelles Anlegen bzw. Abnehmen der Atemschutzmaske, ohne dass der Schutzhelm vom Kopf genommen werden muss, und verringert die Belastung des Benutzers während eines Einsatzes.Out DE 103 14 136 B3 is a holding device for respirators, which are not held by a harness directly to the head of the user, but connected via a special bracket directly to the helmet worn by the user on his head and can be solved by this again, are known. The detachable attachment of the respirator directly to the helmet ensures a quick application or removal of the respirator without the helmet must be removed from the head, and reduces the burden on the user during use.

Bei einer anderen bekannten Kombination aus Atemschutzmaske und Schutzhelm ist an den gegenüberliegenden Seitenwänden jeweils ein gelenkig befestigtes, längenveränderliches Halteelement mit an dessen freiem Ende unter der Wirkung einer Zugfeder teleskopisch gelagertem Befestigungsteil vorgesehen, während an den seitlich gegenüberliegenden Außenflächen des Schutzhelms jeweils eine Hakenaufnahmetasche zum Einhängen des Befestigungsteils entgegen der Federwirkung ausgebildet ist, so dass die Schutzmaske unter Vorspannung am Gesicht des Benutzers gehalten ist. Der Kopplungspunkt des Halteelements am Schutzhelm liegt etwa im Drehpunkt des Schutzhelms, um den sich dieser am Kopf des Benutzers bewegen kann. Bei dieser Art der Befestigung an zwei gegenüberliegenden Punkten an der rechten und linken Kopfseite kann die Atemschutzmaske aufgrund der unterschiedlichen Spannwirkung im Stirn- und im Kinnbereich in Abhängigkeit von der Kopfgröße und -form aber sowohl seitlich als auch von oben nach unten und vom Kinn weg mehr oder weniger leicht verrutschen, so dass der Tragekomfort leidet. Insbesondere beim Tragen der Atemschutzmaske unter Schutzbekleidung können auch Dichtheitsprobleme auftreten. Aus DE 196 25 337 A1 ist eine weitere Art der Verbindung zwischen Atemschutzmaske und Schutzhelm bekannt, die jeweils ein an den gegenüberliegenden Seitenflächen des Schutzhelms gelenkig gelagertes Joch mit an dessen Enden angebrachten Befestigungsmitteln umfasst, die - wie bei einer bekannten Kopfbänderung von Atemschutzmasken - an vier Punkten mit dem Maskenkörper verbunden sind. Diese Verbindung erfordert jedoch viele komplizierte Verstellmöglichkeiten, so dass die Maske nicht schnell und sicher genug angelegt werden kann. Die Kopplungspunkte am Helm sind zudem weit vom Drehpunkt des Helms am Kopf entfernt, so dass bei Helmbewegungen Undichtigkeiten auftreten können. Außerdem ist die bekannte Anordnung nicht kompakt, sondern sehr platzaufwändig ausgebildet.In another known combination of respirator and protective helmet is on the opposite side walls each have a hinged, variable-length holding member provided at the free end under the action of a tension telescopically mounted mounting member, while on the laterally opposite outer surfaces of the helmet each have a hook receiving pocket for attaching the Fastening part is formed against the spring action, so that the protective mask is held under bias on the face of the user. The coupling point of the retaining element on the helmet is approximately in the pivot point of the helmet around which this can move on the head of the user. In this type of attachment to two opposite points on the right and left side of the head, the respirator due to the different clamping effect in the forehead and in the chin area depending on the head size and shape but both sideways as well as from top to bottom and away from the chin more or less easy, so that the wearing comfort suffers. In particular, when wearing the respirator under protective clothing and leakage problems can occur. Out DE 196 25 337 A1 Another type of connection between respiratory mask and protective helmet is known, each comprising a hinged at the opposite side surfaces of the protective helmet yoke mounted at its ends fasteners, which - as in a known headband of respirators - are connected at four points with the mask body , However, this connection requires many complicated adjustments, so that the mask can not be applied quickly and safely enough. The coupling points on the helmet are also far away from the pivot point of the helmet on the head, so that leaks can occur during helmet movements. In addition, the known arrangement is not compact, but very space consuming.

Aus GB 2 417 905 A ist eine Anordnung zur lösbaren Verbindung einer Atemschutzmaske mit einem Schutzhelm gemäß dem Oberbegriff des Anspruchs 1 bekannt. Der Erfindung liegt die Aufgabe zugrunde, eine einfach ausgebildete Haltevorrichtung zur lösbaren Verbindung einer Atemschutzmaske mit einem Schutzhelm anzugeben, die bei aufgesetztem Helm unabhängig von der jeweiligen Kopfform des Benutzers ein einfaches und sicheres Anlegen und einen komfortablen und dichten Sitz der Maske am Gesicht des Benutzers auch unter extremen Einsatzbedingungen gewährleistet und zudem kompakt ausgebildet ist.Out GB 2 417 905 A an arrangement for releasably connecting a respirator with a protective helmet according to the preamble of claim 1 is known. The invention has for its object to provide a simple design holding device for releasably connecting a respirator with a protective helmet, which with the helmet attached, regardless of the particular head shape of the user a simple and secure donning and a comfortable and tight fit of the mask on the user's face guaranteed under extreme conditions and also has a compact design.

Erfindungsgemäß wird die Aufgabe mit einer Anordnung zur lösbaren Verbindung einer Atemschutzmaske mit einem Schutzhelm gemäß den Merkmalen des Patentanspruchs 1 gelöst. Weitere Merkmale und zweckmäßige Ausgestaltungen der erfindungsgemäßen Anordnung ergeben sich aus den Unteransprüchen. Kern der Erfindung ist die Ausbildung der lösbaren Halterung zwischen Atemschutzmaske und Schutzhelm als beidseitige, an den Anbindungsstellen der Halteelemente drehbewegliche Vier-Punkt-Aufhängung. Die drehbewegliche Kopplung der Halteelemente an Helm und Maske wird entweder durch Drehgelenke oder durch eine biegeschlaffe Ausbildung der Halteelemente oder eines am Kopplungspunkt liegenden Endabschnitts der Halteelemente realisiert. An der Atemschutzmaske sind dicht nebeneinander jeweils zwei separate, in der Länge einstellbare Halteelemente, das heißt ein schräg nach oben gerichtetes oberes und ein im Wesentlichen waagerechtes oder leicht nach oben gerichtetes unteres Halteelement in der oben genannten Art drehbeweglich angebracht, deren gegenüberliegende Enden nahe oberhalb bzw. unterhalb des Drehpunktes des Schutzhelms ebenfalls drehbeweglich befestigt sind. Die Lage der drehbeweglichen Kopplungspunkte nahe am Drehpunkt des Schutzhelms auf dem Kopf wird durch das nahe Beieinanderliegen der an der Atemschutzmaske jeweils auf der rechten und linken Seite vorgesehenen drehbeweglichen Kopplungspunkte erreicht. Das heißt, aufgrund der V-förmigen Anordnung der Halteelemente liegen deren Kopplungspunkte am Schutzhelm nahe am Drehpunkt des Schutzhelms um den Kopf des Benutzers. Um den Maskensitz trotz der Drehbewegung des Schutzhelms am Kopf noch weiter zu verbessern, können die drehbeweglichen Kopplungspunkte der Halteelemente am Schutzhelm noch zueinander versetzt angeordnet sein, und zwar derart, dass das der obere drehbewegliche Kopplungspunkt einen geringeren Abstand zur Atemschutzmaske hat als der untere drehbewegliche Kopplungspunkt.According to the invention the object is achieved with an arrangement for the detachable connection of a respirator with a protective helmet according to the features of claim 1. Further features and expedient embodiments of the arrangement according to the invention will become apparent from the dependent claims. The core of the invention is the formation of the detachable holder between respirator and protective helmet as a two-sided, rotatable at the connection points of the holding elements four-point suspension. The rotatable coupling of the holding elements The helmet and mask is realized either by hinges or by a pliable design of the holding elements or an end portion of the holding elements located at the coupling point. On the respirator close to each other two separate, adjustable in length holding elements, that is an obliquely upwardly directed upper and a substantially horizontal or slightly upwardly directed lower support member rotatably mounted in the above manner, the opposite ends close above or . are also mounted rotatably below the pivot point of the helmet. The position of the rotatable coupling points near the pivot point of the protective helmet on the head is achieved by the close juxtaposition of the rotatable coupling points provided on the respirator on the right and left side. That is, due to the V-shaped arrangement of the holding elements are their coupling points on the helmet near the pivot point of the helmet around the head of the user. In order to improve the mask fit even further despite the rotary movement of the protective helmet on the head, the rotatable coupling points of the holding elements on the protective helmet can still be arranged offset to each other, in such a way that the upper rotatable coupling point has a smaller distance to the respirator than the lower rotatable coupling point ,

Mit einer derart ausgebildeten und angeordneten lösbaren Verbindung zwischen Schutzhelm und Atemschutzmaske wird die Atemschutzmaske unabhängig von der jeweiligen Kopfform und - größe und auch unter extremen Einsatzbedingungen und der dabei auftretenden Relativbewegung zwischen Schutzhelm und Kopf des Benutzers gleichmäßig und sicher abdichtend sowohl im Stirnbereich als auch im Kinnbereich am Gesicht des Benutzers gehalten.With such a trained and arranged detachable connection between the helmet and respirator, the respirator is independent of the respective head shape and - size and under extreme conditions and the relative movement between helmet and head of the user uniformly and safely sealing both in the forehead and in the chin area held on the user's face.

Die Drehbeweglichkeit am Kopplungspunkt wird durch ein in Drehgelenken befestigtes, im Wesentlichen steifes Halteelement oder durch ein an den Enden befestigtes, aber als Ganzes oder zumindest an den Endabschnitten biegeschlaffes Halteelement erreicht. Auch eine Kombination aus drehgelenkiger und biegeschlaffdrehbeweglicher Kopplung an der einen und der anderen Seite des betreffenden Halteelements bzw. des oberen oder des unteren Haltelements ist denkbar.The rotational mobility at the coupling point is determined by a substantially rigid retaining element fixed in pivots or by a end attached but as a whole or at least reaches the slippery holding element at the end sections. A combination of pivotable and slidably rotatable coupling on one side and the other side of the relevant holding element or of the upper or the lower holding element is also conceivable.

Die Halteelemente können zudem innerhalb oder außerhalb der Helmschale in der oben beschriebenen Art drehbeweglich angebracht sein.The holding elements can also be rotatably mounted inside or outside of the helmet shell in the manner described above.

Mit Hilfe eines am Schutzhelm vorgesehenen Befestigungselements zum Einhängen der Halteelemente kann die Atemschutzmaske einfach und schnell angelegt bzw. abgenommen werden. Es ist aber auch denkbar, die Verbindung zwischen der Maske und dem Helm durch Einhängen der am Helm befestigten Halteelemente an einem an der Atemschutzmaske ausgebildeten Befestigungselement herzustellen.With the help of a provided on the protective helmet fastener for hanging the retaining elements, the respirator can be easily and quickly applied or removed. However, it is also conceivable to make the connection between the mask and the helmet by attaching the retaining elements attached to the helmet to a fastening element formed on the respiratory mask.

Gemäß einem weiteren Merkmal der Erfindung ist der helmseitige obere drehbewegliche Kopplungspunkt näher am Drehpunkt des Schutzhelms angeordnet als der helmseitige untere drehbewegliche Kopplungspunkt.According to a further feature of the invention, the helmet-side upper rotatable coupling point is arranged closer to the pivot point of the protective helmet than the helmet-side lower rotatable coupling point.

Gemäß einer bevorzugten Ausführungsform sind die helmseitigen Enden der Halteelemente über die drehbeweglichen Kopplungspunkte jeweils an einem gemeinsamen Verbindungsjoch befestigt, das, um die vorgegebenen Kopplungspunkte der Halteelemente am Schutzhelm auch bei unterschiedlicher Belastung der Halteelemente beizubehalten, verdrehsicher, aber lösbar, jeweils in ein am Schutzhelm ausgebildetes, mit Ausnehmungen versehenes Befestigungselement einhängbar ist. Ein vom Verbindungsjoch abstrebendes Befestigungsteil kann auch am Schutzhelm verdrehsicher - geführt - einhängbar sein.According to a preferred embodiment, the helm-side ends of the holding elements are each attached via the rotatable coupling points to a common connection yoke which, in order to maintain the predetermined coupling points of the holding elements on the protective helmet even with different loading of the holding elements, twisting, but releasable, each trained in a protective helmet , Fastener provided with recesses can be suspended. An abstrebendes from the connecting yoke fastening part can also be against rotation on the helmet - guided - be suspended.

In weiterer Ausbildung der Erfindung sind die biegeschlaffen oder im Wesentlichen biegesteifen Halteelemente am Sichtscheibenrahmen der Atemschutzmaske an einem gemeinsamen Maskenanbindungsteil drehbeweglich gehalten.In a further embodiment of the invention, the sluggish or substantially rigid retaining elements on the lens frame of the respirator are rotatably held on a common mask connection part.

In Ausgestaltung der Erfindung kann auch das Maskenanbindungsteil selbst drehbar, und gegebenenfalls auch lösbar, an der Maske bzw. am Sichtscheibenrahmen befestigt sein, um durch die Drehbeweglichkeit einerseits bei Helmbewegungen den sicheren Sitz der Maske zu gewährleisten und gegebenenfalls die Halterung zum Anlegen oder Abnehmen der Atemschutzmaske in diesem Bereich befestigen bzw. lösen zu können.In an embodiment of the invention, the mask connection part itself rotatable, and possibly also releasably secured to the mask or the lens frame to ensure the rotational fit on the one hand helmet movements the secure fit of the mask and optionally the holder for applying or removing the respirator be able to attach or detach in this area.

In Ausgestaltung der Erfindung können die Halteelemente oder auch das Maskenanbindungsteil längenverstellbar sein, um die Maske zum Gesicht des Benutzers hin zu justieren.In an embodiment of the invention, the holding elements or the mask connecting part may be adjustable in length in order to adjust the mask towards the user's face.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung näher erläutert. Es zeigen:

An embodiment of the invention will be explained in more detail with reference to the drawing. Show it:
Fig. 1
a side view of a protective helmet with this on a holding device releasably attached respirator;
Fig. 2
a side view of the respirator after Fig. 1 ; and
Fig. 3
a side view according to Fig. 1 , but with another attachment of the respirator to the helmet.

Die Haltevorrichtung umfasst jeweils ein für beide Seiten des Schutzhelms 1 vorgesehenes, mit Befestigungshaken 2a, 2b versehenes Verbindungsjoch 3, das in Ausnehmungen 4a, 4b eines an der Seitenwand des Schutzhelms 1 ausgebildeten Befestigungselements 4 eingehängt werden kann und in diesem durch ein Rastelement 5 arretierbar ist. Das Verbindungsjoch 3 kann somit beim Anlegen der Atemschutzmaske 6 auf einfache Weise am Schutzhelm 1 eingehängt und zum Abnehmen der Atemschutzmaske 6 wieder ausgehängt werden. An den beiden Enden des Verbindungsjochs 3 sind über ein helmseitiges oberes Drehgelenk ein oberes Halteelement 8 und über ein unteres helmseitiges Drehgelenk 9 ein unteres Halteelement 10 gelenkig befestigt. Die beiden längenverstellbar ausgeführten Halteelemente 8 und 10 sind V-förmig zu einem gemeinsamen, am Sichtscheibenrahmen 11 der Atemschutzmaske 6 angebrachten Maskenanbindungsteil 12 geführt und jeweils über ein maskenseitiges oberes und unteres Drehgelenk 13, 15 gelenkig mit diesem verbunden. Der Schutzhelm 1 hat am Kopf des Benutzers einen in einer gedachten waagerechten Drehachse des Kopfes des Benutzers liegenden Drehpunkt 14, der zwischen dem oberen und dem unteren Drehgelenk 7, 9 am Verbindungsjoch 3, vorzugsweise aber näher am oberen Drehgelenk 7, liegt. Das obere helmseitige Drehgelenk 7 des oberen Halteelements 8 liegt in einem Abstand zwischen 10 und 60 mm zur Atemschutzmaske 6 hin oberhalb des Drehpunktes 14, während sich das untere helmseitige Drehgelenk 9 des unteren Halteelements 10 in einem Abstand zwischen 20 und 80 mm von der Atemschutzmaske 6 weg unterhalb des Drehpunktes 14 befindet. Die ausgehend vom Sichtscheibenrahmen 11 V-förmig aufgespreizten Halteelemente 8 und 10 liegen am Maskenanbindungsteil 12 eng nebeneinander, so dass sich auch die Drehgelenke 7 und 9 möglichst nah am Drehpunkt 14 des Schutzhelms 1 befinden. Aufgrund dieser Anordnung der Drehgelenke 7, 9 bzw. des Verbindungsjochs 3 sowie der Halteelemente 8 und 10 bleibt eine Drehbewegung des Schutzhelms 1 am Kopf des Benutzers im Wesentlichen ohne Einfluss auf den Sitz der Atemschutzmaske 6 am Gesicht des Benutzers. Auch durch die aufgrund des unterschiedlichen Abstands der oberen und unteren helmseitigen Drehgelenke 7, 9 versetzte Anordnung der Kopplungspunkte kann die Relativbewegung zwischen Schutzhelm und Atemschutzmaske minimiert werden.The holding device comprises in each case one provided for both sides of the protective helmet 1, provided with fastening hooks 2a, 2b connecting yoke 3, which can be suspended in recesses 4a, 4b of a formed on the side wall of the protective helmet 1 fastener 4 and in this by a locking element 5 can be locked , The connection yoke 3 can thus be hung when applying the respirator 6 in a simple way on the helmet 1 and posted to remove the respirator 6 again. At the two ends of the connecting yoke 3, an upper retaining element 8 and a lower one are provided via a helical upper hinge helmseitiges pivot 9 a lower support member 10 hingedly attached. The two length-adjustable running holding elements 8 and 10 are V-shaped to a common, mounted on the window frame 11 of the respirator 6 mask connection part 12 and each connected via a mask-side upper and lower pivot 13, 15 articulated thereto. The protective helmet 1 has at the user's head a lying in an imaginary horizontal axis of rotation of the user's head pivot 14 which is located between the upper and lower pivot 7, 9 on the connecting yoke 3, but preferably closer to the upper pivot 7. The upper helm-side rotary joint 7 of the upper support member 8 is located at a distance between 10 and 60 mm to the respirator 6 out above the pivot point 14, while the lower helmseitige pivot 9 of the lower support member 10 at a distance between 20 and 80 mm from the respirator. 6 away below the pivot point 14 is located. The starting from the lens frame 11 V-shaped spread holding elements 8 and 10 are close to the mask connection part 12 side by side, so that the hinges 7 and 9 are as close to the pivot point 14 of the helmet. Due to this arrangement of the swivel joints 7, 9 or of the connecting yoke 3 and the holding elements 8 and 10, a rotational movement of the protective helmet 1 on the head of the user remains essentially without influence on the seat of the respirator 6 on the face of the user. Also due to the offset due to the different distance of the upper and lower helmseitigen pivots 7, 9 arrangement of the coupling points, the relative movement between the protective helmet and respirator can be minimized.

Über die gelenkige Halterung der Halteelemente 8, 10 in den Drehgelenken 7, 9 am Verbindungsjoch 3 und den Drehgelenken 13, 15 am Maskenanbindungsteil 12 ist die richtige Höheneinstellung der Atemschutzmaske 6 am Gesicht des Benutzers möglich, während die Längeneinstellung der Halteelemente 8, 10 ein dichtes Anliegen der Atemschutzmaske 6 am Gesicht bewirkt. Das V-förmige Aufspreizen der Halteelemente 8 und 10 mit einem im Wesentlichen waagerecht verlaufenden oder leicht schräg nach oben gerichteten unteren Halteelement 10 und einem schräg nach oben verlaufenden oberen Halteelement 8 gewährleistet ein gleichmäßiges Anliegen der Atemschutzmaske im oberen und im unteren Gesichtsbereich, indem das obere Halteelement 8 die Atemschutzmaske 6 dicht an das Gesicht bringt, und zwar mit höherer Anpresskraft an der Stirn als am Kinn, und das im Wesentlichen waagerechte untere Halteelement 10 die Atemschutzmaske 6 in Richtung des Kinns zieht, und dadurch einen an den Benutzer angepassten sicheren Sitz am Kinn gewährleistet. Wichtig ist dabei die gelenkige und nahe dem Drehpunkt 14 vorgesehene Anordnung der Drehgelenke 7, 9 der beiden Halteelemente 8 und 10 am Schutzhelm 1 sowie der Drehgelenke 13, 15 am Maskenanbindungsteil 12, um einen Einfluss von Relativbewegungen zwischen dem Schutzhelm und der Atemschutzmaske 6 auf den Dichtsitz der Maske weitgehend auszuschließen und auch während eines Einsatzes einen komfortablen und sicheren Sitz der Atemschutzmaske zu garantieren.About the articulated mounting of the support members 8, 10 in the pivot joints 7, 9 on the connecting yoke 3 and the pivot joints 13, 15 on the mask connection part 12, the correct height adjustment of the respirator 6 on the user's face is possible, while the length adjustment of the holding elements 8, 10 a dense Concerns of the respirator 6 causes the face. The V-shaped spreading of the holding elements 8 and 10th with a substantially horizontally extending or slightly obliquely upward upper support member 10 and an obliquely upwardly extending upper support member 8 ensures a uniform concern the respirator in the upper and lower facial area by the upper support member 8 brings the respirator 6 close to the face , with higher contact force on the forehead than on the chin, and the substantially horizontal lower support member 10 pulls the respirator 6 in the direction of the chin, thereby ensuring a user-adapted secure fit on the chin. It is important that the articulated and provided near the pivot point 14 arrangement of the hinges 7, 9 of the two holding elements 8 and 10 on the helmet 1 and the hinges 13, 15 on the mask connecting part 12 to influence relative movements between the helmet and the respirator 6 on the Sealing fit of the mask largely excluded and to guarantee a comfortable and secure fit of the respirator even during use.

Fig. 3 zeigt noch eine andere Ausführungsvariante der Verbindung der Atemschutzmaske 6 mit dem Schutzhelm 1, bei der das Verbindungsjoch 3', an dessen Enden das obere und das - im Wesentlichen waagerecht verlaufende - untere Halteelement 8, 10 jeweils über ein Drehgelenk 7, 9 gehalten ist, ein senkrecht von diesem abstrebendes Befestigungsteil 16 aufweist. Das Befestigungsteil 16 wird in eine in der Seitenwand des Schutzhelms 1 gebildete Ausnehmung 17 eingehängt, ist aber gleichzeitig am Schutzhelm 1 verdrehsicher, hier mittels einer strichliert angedeuteten Nut-Feder-Verbindung 18, gehalten. Das obere und das untere Halteelement 8, 10 sind längenverstellbar und - aufgrund einer biegeschlaffen Ausbildung der Halteelemente - drehbeweglich mit dem Maskenanbindungsteil 12 verbunden. Fig. 3 shows yet another embodiment of the compound of the respirator 6 with the protective helmet 1, in which the connecting yoke 3 ', at the ends of the upper and the - substantially horizontally extending - lower support member 8, 10 is respectively held by a hinge 7, 9, a perpendicular from this abstrebendes fastening part 16 has. The fastening part 16 is suspended in a recess 17 formed in the side wall of the protective helmet 1, but at the same time on the protective helmet 1 against rotation, here by means of a dashed line indicated tongue and groove connection 18, held. The upper and the lower holding element 8, 10 are adjustable in length and - due to a pliable design of the holding elements - rotatably connected to the mask connection part 12.

Die Erfindung ist nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. Beispielsweise können die Halteelemente 8 und 10 auch ohne Verbindungsjoch einzeln, jedoch drehbeweglich und in den oben angegebenen - drehpunktnahen und schräg versetzten - Positionen, am Schutzhelm 1 angebracht werden, und das Maskenanbindungsteil kann als Verdreh- und Längsverschiebungselement, das auch lösbar mit dem Sichtscheibenrahmen 11 oder dem Maskenkörper verbunden sein kann, ausgeführt sein.The invention is not limited to the embodiment described above. For example, the holding elements 8 and 10 without connection yoke individually, but rotatably and in the above - drehpunktnahen and obliquely offset - positions, be attached to the helmet 1, and the mask connection part can as Verdreh- and longitudinal displacement element, which is also detachable with the lens frame 11th or may be connected to the mask body executed.
