Description

Die Erfindung betrifft ein Kopfschutzsystem mit einem Schutzhelm und einem Brandschutztuch.The invention relates to a head protection system with a protective helmet and a fire protection cloth.

Es ist bekannt, zum Schutz vor heißen Materialien, Strahlungswärme und Flammen ein Brandschutztuch im Bereich des Nackens zusätzlich zu einem Feuerwehrhelm zu benutzen. Eine besondere Form solch eines Brandschutztuches, auch Hollandtuch oder Integraltuch genannt, schützt zusätzlich sensible Bereiche wie die Stirn, Teile des Gesichts und den vorderen und seitlichen Hals. In Kombination mit einer Atemschutzmaske kann dadurch ein vollumschließender Schutz des Kopfes für einen Feuerwehrmann entstehen. Bereits bekannte Brandschutztücher werden durch einen Klettverschluss, durch Druckknöpfe oder durch eigens dafür vorgesehene Kunststoffbügel an dem entsprechenden Schutzhelm, wie beispielsweise an dem Feuerwehrhelm angebracht.It is known to use a fire protection cloth in the area of the neck in addition to a firefighter's helmet to protect against hot materials, radiant heat and flames. A special form of such a fire protection cloth, also known as a Holland cloth or integral cloth, also protects sensitive areas such as the forehead, parts of the face and the front and side neck. In combination with a respirator, this can provide full head protection for a firefighter. Fire protection cloths that are already known are attached to the corresponding protective helmet, such as the fire brigade helmet, by means of a Velcro fastener, snap fasteners or plastic brackets specially provided for this purpose.

EP 1 885 209 B1 beschreibt ein Integraltuch, das mittels zweier Bügel aus elastisch verformbarem Material über Einhakmittel mit einem Schutzhelm verbunden werden kann. EP 1 885 209 B1 describes an integral cloth that can be connected to a protective helmet by means of two brackets made of elastically deformable material via hooking means.

DE 87 14 490 U1 beschreibt einen Schutzhelm mit im Kantenbereich angeordneten Ausnehmungen zur gleichzeitigen Aufnahme von verschiedenen Anbauelementen, besonders einen Nackenschutz. DE 87 14 490 U1 describes a protective helmet with recesses arranged in the edge area for the simultaneous accommodation of various add-on elements, in particular a neck protector.

Aufgabe der vorliegenden Erfindung ist es, ein verbessertes Kopfschutzsystem, insbesondere ein Kopfschutzsystem mit einem hohen Tragekomfort und einem hohen Maß an Sicherheit für den Träger des Kopfschutzsystems zu ermöglichen. Erfindungsgemäß wird zur Lösung dieser Aufgabe ein Kopfschutzsystem mit einem Schutzhelm und einem Brandschutztuch vorgeschlagen.The object of the present invention is to enable an improved head protection system, in particular a head protection system with a high degree of wearing comfort and a high degree of safety for the wearer of the head protection system. According to the invention, a head protection system with a protective helmet and a fire protection cloth is proposed to solve this problem.

Der Schutzhelm weist eine Helmschale und eine Haltevorrichtung zum Gewährleisten eines Abstands zwischen einer Innenseite der Helmschale und einem Kopf eines Trägers des Schutzhelms im getragenen Zustand des Schutzhelms auf. Dabei resultiert aufgrund des Abstands zwischen der Innenseite der Helmschale und dem Kopf des Trägers ein Luftweg zwischen Schutzhelm und Kopf, wobei der Luftweg teilweise gebildet wird durch eine Mehrzahl von Öffnungen eines Befestigungsrings, und wobei der Befestigungsring im getragenen Zustand des Schutzhelms zumindest im Bereich der Stirn des Trägers angeordnet ist.The protective helmet has a helmet shell and a holding device for ensuring a distance between an inside of the helmet shell and a head of a wearer of the protective helmet in the wearing state of the protective helmet. The distance between the inside of the helmet shell and the head of the wearer results in an air passage between the protective helmet and the head, the air passage being formed in part by a plurality of openings in a fastening ring, and the fastening ring being in the worn state of the protective helmet at least in the area of the forehead of the carrier is arranged.

Das Brandschutztuch weist ein Befestigungsband auf, wobei das Befestigungsband eine Mehrzahl von starren Befestigungselementen aufweist, die jeweils dazu ausgebildet sind, in eine jeweilige Öffnung des Befestigungsrings einzugreifen und dadurch das Brandschutztuch an dem Schutzhelm lösbar zu befestigen. Dabei füllt die Mehrzahl von starren Befestigungselementen im befestigten Zustand die Mehrzahl von Öffnungen derart aus, dass der Luftweg durch die Mehrzahl von Öffnungen geschlossen ist.The fire protection sheet has a fastening strap, the fastening strap having a plurality of rigid fastening elements which are each configured to engage in a respective opening of the fastening ring and thereby releasably fasten the fire protection sheet to the protective helmet. In this case, the plurality of rigid fastening elements in the fastened state fills the plurality of openings in such a way that the air path through the plurality of openings is closed.

Im Rahmen der Erfindung wurde erkannt, dass es für eine Benutzung des Schutzhelms ohne Brandschutztuch vorteilhaft ist, wenn der Kopf gut belüftet ist, wohingegen während der Feuerbekämpfung bei gleichzeitiger Verwendung des Brandschutztuches, sehr heiße Luft auf der Innenseite der Helmschale vermieden werden sollte. Weiterhin wurde erkannt, dass das Brandschutztuch, neben der bekannten Schutzfunktionen für den Kopf, Öffnungen zur Durchlüftung an der Helmschale verschließen kann.In the context of the invention, it was recognized that it is advantageous for using the protective helmet without a fire protection cloth if the head is well ventilated, whereas during firefighting with the simultaneous use of the fire protection cloth, very hot air on the inside of the helmet shell should be avoided. Furthermore, it was recognized that the fire protection cloth, in addition to the known protective functions for the head, can close openings for ventilation on the helmet shell.

Das erfindungsgemäße Kopfschutzsystem ermöglicht somit vorteilhaft eine besonders gute Belüftung des Kopfes eines Trägers des Schutzhelms über den bereitgestellten Luftweg, solange kein Brandschutztuch an dem Schutzhelm befestigt ist. Weiterhin ermöglicht das erfindungsgemäße Kopfschutzsystem einen sicheren Schutz des Kopfes vor heißer Umgebungsluft durch Schutzhelm und Brandschutztuch aufgrund des Schließens der Mehrzahl von Öffnungen und das dadurch ermöglichte zumindest teilweise Schließen des Luftweges.The head protection system according to the invention thus advantageously enables particularly good ventilation of the head of a wearer of the protective helmet via the provided airway, as long as no fire protection cloth is attached to the protective helmet. Furthermore, the head protection system according to the invention enables reliable protection of the head from hot ambient air by means of a protective helmet and fire protection cloth due to the closing of the plurality of openings and the at least partial closing of the airway made possible by this.

Weiterhin verfügt das erfindungsgemäße Kopfschutzsystem vorteilhaft über aufeinander abgestimmte Bestandteile, nämlich den Befestigungsring des Schutzhelms und das Befestigungsband des Brandschutztuches. Diese beiden Bestandteile treten erfindungsgemäß dadurch in Wechselwirkung, dass eine Befestigung des Brandschutztuches über das Befestigungsband an dem Befestigungsring dazu führt, dass der Luftweg durch die Mehrzahl von Öffnungen geschlossen ist.Furthermore, the head protection system according to the invention advantageously has coordinated components, namely the fastening ring of the safety helmet and the fastening strap of the fire protection cloth. According to the invention, these two components interact in that fastening the fire protection cloth to the fastening ring via the fastening strip results in the air path being closed by the plurality of openings.

Erfindungsgemäß bedeutet ein Schließen der Öffnungen, dass diese Öffnungen im Wesentlichen für den Luftweg geschlossen sind. Erfindungsgemäß kann der Luftweg neben diesen Öffnungen auch über andere Wege auf der Innenseite der Helmschale ausgebildet sein, so dass das Schließen der Mehrzahl von Öffnungen zu einer zumindest teilweisen Reduzierung von Luft innerhalb des Luftweges führt.According to the invention, closing the openings means that these openings are essentially closed to the airway. According to the invention, the air path can also be formed in other ways on the inside of the helmet shell in addition to these openings, so that the closing of the plurality of openings leads to an at least partial reduction of air within the air path.

Der erfindungsgemäße Schutzhelm ist insbesondere ein Feuerwehrhelm. Die Vorteile der Erfindung sind besonders relevant für den Einsatz des Kopfschutzsystems in Gebieten mit heißer Umgebungsluft, also insbesondere für den Einsatz im Rahmen der Feuerwehrtätigkeit.The protective helmet according to the invention is in particular a firefighter's helmet. The advantages of the invention are particularly relevant for the use of the head protection system in areas with hot ambient air, ie in particular for use as part of fire service activities.

Der Luftweg wird erfindungsgemäß unter anderem durch die Mehrzahl von Öffnungen des Befestigungsrings gebildet. Vorzugsweise besteht der Luftweg dabei aus einer Mehrzahl von Luftwegsbereichen, wobei jeder Öffnung ein Luftwegsbereich zugeordnet ist. Die Mehrzahl von Luftwegsbereichen kann zusammenhängend oder nicht zusammenhängend ausgebildet sein.According to the invention, the airway is formed, among other things, by the plurality of openings of the fastening ring. The airway preferably consists of a plurality of airway areas, with each opening being assigned an airway area. The plurality of airway regions may be contiguous or discontinuous.

Neben der Mehrzahl von starren Befestigungselementen können weitere Bestandteile des Befestigungsbandes und/oder des Befestigungsrings vorgesehen sein, um eine zuverlässige Befestigung des Befestigungsbandes an dem Befestigungsring zu ermöglichen.In addition to the plurality of rigid fastening elements, further components of the fastening strap and/or the fastening ring can be provided in order to enable the fastening strap to be reliably fastened to the fastening ring.

Erfindungsgemäß ist ein starres Befestigungselement ein Befestigungsmittel, das geeignet ist, aufgrund seiner starren Struktur eine jeweilige Öffnung zu verschließen während es im Bereich der Öffnungen befestigt ist. Insbesondere kann das starre Befestigungselement in einem befestigten Zustand des Brandschutztuches an dem Schutzhelm direkt vor einer jeweiligen Öffnung angeordnet sein und aufgrund einer dadurch auf das Befestigungsband wirkenden Spannkraft zu der Befestigung des Befestigungsbandes an dem Schutzhelm beitragen. Hierbei werden die starren Befestigungselemente typischerweise durch weitere Bestandteile des Befestigungsbandes und/oder des Befestigungsrings ergänzt, die ebenfalls zu einer zuverlässigen Befestigung des Befestigungsbandes an dem Befestigungsring beitragen.According to the invention, a rigid fastening element is a fastening means which, due to its rigid structure, is suitable for closing a respective opening while it is fastened in the area of the openings. In particular, the rigid fastening element can be positioned directly in front of a respective opening when the fire protection cloth is in a fastened state on the protective helmet be arranged and contribute to the attachment of the fastening strap to the protective helmet due to a tensioning force thereby acting on the fastening strap. In this case, the rigid fastening elements are typically supplemented by further components of the fastening strap and/or the fastening ring, which also contribute to a reliable fastening of the fastening strap to the fastening ring.

Der Befestigungsring kann auch ausschließlich im Bereich der Stirn des Trägers ausgebildet sein, wobei dann im Bereich des Hinterkopfes des Trägers typischerweise ein weiteres Befestigungsteil an dem Schutzhelm vorgesehen ist, um eine stabile Befestigung des Brandschutztuches an dem Schutzhelm sicherzustellen. Insbesondere kann der Befestigungsring mehrteilig ausgebildet sein.The fastening ring can also be formed exclusively in the area of the wearer's forehead, in which case a further fastening part is typically provided on the protective helmet in the area of the back of the wearer's head in order to ensure stable attachment of the fire protection cloth to the protective helmet. In particular, the fastening ring can be designed in several parts.

Über eine derartige Zahnung kann eine besonders stabile Befestigung des Befestigungsbandes an dem Befestigungsring ermöglicht werden. Weiterhin ermöglicht eine derartige Zahnung eine besonders gleichmäßige Befestigung des Befestigungsbandes an dem Befestigungsring und mithin auch eine gleichmäßige Kraftverteilung bei einer auf das Brandschutztuch wirkenden Zugkraft.In an advantageous embodiment, the fastening elements form teeth on the fastening strap. A particularly stable fastening of the fastening strap to the fastening ring can be made possible via such toothing. Furthermore, such allows Teeth a particularly uniform attachment of the fastening tape to the fastening ring and therefore also a uniform distribution of force in a tensile force acting on the fire protection cloth.

In einer vorteilhaften Ausführungsform sind die Befestigungselemente des Befestigungsbands im Wesentlichen rechteckig ausgebildet. In einer alternativen oder ergänzenden Ausführungsform sind die Befestigungselemente oval, dreieckig und/oder halbkreisförmig ausgebildet. Vorteilhaft ist in einer Variante dieser Ausführungsform die einem jeweiligen Befestigungselement zugeordnete Öffnung aus der Mehrzahl von Öffnungen ebenfalls im Wesentlichen rechteckig, oval, dreieckig und/oder halbkreisförmig ausgebildet. So kann das jeweilige Befestigungselement die jeweilige Öffnung aus der Mehrzahl von Öffnungen zuverlässig schließen. Weiterhin erlauben die Formen der Öffnungen gemäß dieser Ausführungsform große Öffnungen im Vergleich zu konkaven Formen, so dass eine besonders gute Belüftung des Kopfes für den Fall eines nicht an dem Schutzhelm befestigten Brandschutztuches möglich ist.In an advantageous embodiment, the fastening elements of the fastening strap are of essentially rectangular design. In an alternative or supplementary embodiment, the fastening elements are oval, triangular and/or semicircular. In a variant of this embodiment, the opening assigned to a respective fastening element from the plurality of openings is advantageously also essentially rectangular, oval, triangular and/or semicircular. In this way, the respective fastening element can reliably close the respective opening from the plurality of openings. Furthermore, the shapes of the openings according to this embodiment allow large openings compared to concave shapes, so that a particularly good ventilation of the head is possible in the event of a fire protection cloth not being attached to the protective helmet.

In einer weiteren Ausführungsform weisen die Befestigungselemente und/oder die Öffnungen untereinander unterschiedliche Formen auf. Hierdurch kann abhängig von der Form des Schutzhelms ein besonders effektiver Luftweg, insbesondere ein Luftweg mit besonders guter Belüftung des Kopfes bereitgestellt werden.In a further embodiment, the fastening elements and/or the openings have different shapes from one another. As a result, depending on the shape of the protective helmet, a particularly effective airway, in particular an airway with particularly good ventilation of the head, can be provided.

In einer besonders bevorzugten Ausführungsform ist das Brandschutztuch ein Hollandtuch. Dadurch kann der Kopf des Trägers des Kopfschutzsystems besonders effektiv vor Flammen und heißer Umgebungsluft geschützt werden.In a particularly preferred embodiment, the fire protection cloth is a Holland cloth. As a result, the head of the wearer of the head protection system can be protected particularly effectively against flames and hot ambient air.

In einer besonders bevorzugten Ausführungsform ist der Schutzhelm derart ausgebildet, dass der Luftweg zwischen Schutzhelm und Kopf im befestigten Zustand des Brandschutztuches komplett geschlossen ist. Hierdurch kann besonders zuverlässig sichergestellt werden, dass im Falle eines an dem Schutzhelm befestigten Brandschutztuches nahezu keine heiße Umgebungsluft durch die Öffnungen zur Innenseite der Helmschale dringen kann. In einer besonders vorteilhaften Variante dieser Ausführungsform ist der Schutzhelm ein Feuerwehrhelm.In a particularly preferred embodiment, the protective helmet is designed in such a way that the airway between the protective helmet and the head is completely closed when the fire protection cloth is in the fastened state. In this way it can be ensured in a particularly reliable manner that, in the case of a fire protection cloth attached to the protective helmet, almost no hot ambient air can penetrate through the openings to the inside of the helmet shell. In one In a particularly advantageous variant of this embodiment, the protective helmet is a firefighter's helmet.

In einer weiteren vorteilhaften Ausführungsform umfasst das Befestigungsband zusätzlich zu der Mehrzahl von starren Befestigungselementen eine Mehrzahl von Befestigungsteilen, die dazu ausgebildet sind, das Brandschutztuch an dem Schutzhelm lösbar zu befestigen. Vorzugsweise bildet die Mehrzahl von Befestigungsteilen eine robuste zuverlässige Befestigung, die durch die Mehrzahl von starren Befestigungselementen lediglich ergänzt wird. Vorzugsweise ist die Mehrzahl von Befestigungsteilen nicht in unmittelbarer Nachbarschaft zu der Mehrzahl von Öffnungen ausgebildet. Hierdurch kann eine Befestigung über die Befestigungsteile besonders zuverlässig sein. Die Befestigung über die Befestigungsteile erfordert entsprechende Befestigungsbereiche an dem Befestigungsring. Dabei sind ein entsprechender Befestigungsteil und ein entsprechender Befestigungsbereich derart aufeinander abgestimmt, dass zwischen Befestigungsteil und Befestigungsbereich eine formschlüssige Verbindung, vorzugsweise eine formschlüssige und/oder kraftschlüssige Verbindung, möglich ist. In einer besonders bevorzugten Variante dieser Ausführungsform ermöglicht die Mehrzahl von starren Befestigungselementen eine besonders einfache und geeignete Anordnung des Brandschutztuches an dem Schutzhelm, wobei jedoch nur die Mehrzahl von Befestigungsteilen das Brandschutztuch bei auftretenden Zugkräften wirksam an dem Schutzhelm befestigt. Vorzugsweise erlaubt die Mehrzahl von starren Befestigungselementen in dieser Variante eine Sicherung der Lage des Brandschutztuches relativ zu dem Schutzhelm bei auftretenden Querkräften. Querkräfte sind dabei Kräfte mit einer Komponente in Richtung der lateralen Ausdehnung des Befestigungsbandes.In a further advantageous embodiment, the fastening strap comprises, in addition to the plurality of rigid fastening elements, a plurality of fastening parts which are designed to detachably fasten the fire protection sheet to the protective helmet. The plurality of fastening parts preferably forms a robust, reliable fastening which is only supplemented by the plurality of rigid fastening elements.

Fig. 1 zeigt eine schematische Darstellung eines Schutzhelms 100 gemäß einem ersten Ausführungsbeispiel eines erfindungsgemäßen Kopfschutzsystems. 1 shows a schematic representation of a protective helmet 100 according to a first exemplary embodiment of a head protection system according to the invention.

Der Schutzhelm 100 hat eine Helmschale 105 und eine Haltevorrichtung 108 zum Gewährleisten eines Abstands zwischen einer Innenseite 106 der Helmschale 105 und einem Kopf 102 eines Trägers des Schutzhelms 100 im getragenen Zustand des Schutzhelms 100. Die Außenseite 107 der Helmschale 105 ist ohne jegliche Öffnungen ausgebildet, um eine Schutzfunktion gegenüber heißen Materialien, heißer Umgebungsluft und Flammen zu gewährleisten. Aufgrund des Abstands A zwischen der Innenseite 106 der Helmschale 105 und dem Kopf 102 des Trägers resultiert ein Luftweg 110 zwischen Schutzhelm 100 und Kopf 102. Dieser Luftweg 110 wird teilweise gebildet durch eine Mehrzahl von Öffnungen 120 eines Befestigungsrings 125. Die Luftführung innerhalb des Luftweges 110 kann abhängig von den thermischen Umgebungsverhältnissen unterschiedlich ausgebildet sein. Der Luftweg 110 führt vorliegend durch die durch eine geeignete Bänderung gebildete Haltevorrichtung 108 hindurch und wird nur teilweise durch die Mehrzahl von Öffnungen 120 begrenzt. Insbesondere ist der Luftweg im Bereich der Stirn des Kopfes 102 nicht ausschließlich durch den Befestigungsring 125 begrenzt, so dass die Luft aus dem Luftweg 110 an der Stirn frei austreten kann.The protective helmet 100 has a helmet shell 105 and a holding device 108 to ensure a distance between an inner side 106 of the helmet shell 105 and a head 102 of a wearer of the protective helmet 100 when the protective helmet 100 is worn. The outer side 107 of the helmet shell 105 is designed without any openings, to ensure a protective function against hot materials, hot ambient air and flames. Due to the distance A between the inside 106 of the helmet shell 105 and the head 102 of the wearer, an airway 110 results between the protective helmet 100 and the head 102. This airway 110 is partially formed by a plurality of openings 120 of a fastening ring 125. The air flow within the airway 110 can be designed differently depending on the thermal ambient conditions. In the present case, the airway 110 leads through the holding device 108 formed by a suitable harness and is only partially delimited by the plurality of openings 120 . In particular, the airway in the area of the forehead of the head 102 is not limited exclusively by the fastening ring 125, so that the air can freely exit the airway 110 at the forehead.

Der Befestigungsring 125 ist im getragenen Zustand des Schutzhelms zumindest im Bereich der Stirn des Trägers angeordnet. In dem dargestellten Ausführungsbeispiel ist der Befestigungsring 125 nur im Bereich der Stirn ausgebildet und an einem Dämpfungselement 112 angeordnet, das an der Innenseite 106 der Helmschale 105 befestigt ist. Der Befestigungsring 125 ist dabei an das Dämpfungselement 112 geklebt. In einem nicht dargestellten Ausführungsbeispiel ist der Befestigungsring kraftschlüssig und/oder formschlüssig an dem Dämpfungselement oder direkt an der Helmschale befestigt.When the protective helmet is being worn, the fastening ring 125 is arranged at least in the area of the forehead of the wearer. In the exemplary embodiment shown, the fastening ring 125 is only formed in the area of the forehead and is arranged on a damping element 112 which is fastened to the inside 106 of the helmet shell 105 . The fastening ring 125 is glued to the damping element 112 . In an exemplary embodiment that is not shown, the fastening ring is fastened to the damping element or directly to the helmet shell in a non-positive and/or positive manner.

Die Öffnungen 120 aus der Mehrzahl von Öffnungen sind in dem dargestellten Ausführungsbeispiel rechteckig geformt. Dabei hat eine jeweilige Öffnung eine Breite B1 von mindestens 0,3 cm, insbesondere mindestens 0,5 cm, besonders bevorzugt mindestens 1 cm. Weiterhin hat eine jeweilige Öffnung eine Höhe H1 von mindestens 0,3 cm, insbesondere mindestens 0,5 cm, besonders bevorzugt mindestens 1 cm.The openings 120 of the plurality of openings are rectangular shaped in the illustrated embodiment. Each opening has a width B1 of at least 0.3 cm, in particular at least 0.5 cm, particularly preferably at least 1 cm. Furthermore, each opening has a height H1 of at least 0.3 cm, in particular at least 0.5 cm, particularly preferably at least 1 cm.

Neben der Haltevorrichtung 108 ist an der Helmschale 105 im Bereich des Hinterkopfes ein Abstandselement 114 angeordnet, welches dafür sorgt, dass die Helmschale 105 in diesem Bereich nicht gegen den Kopf 102 des Trägers des Schutzhelms 100 stößt. Der dargestellte Abstand A ist der geringste Abstand zwischen der Innenseite 106 der Helmschale 105 und dem Kopf 102. In dem dargestellten Ausführungsbeispiel beträgt der Abstand A mindestens 0,3 cm, insbesondere mindestens 0,7 cm, besonders bevorzugt mindestens 1,3 cm.A spacer element 114 is arranged next to the holding device 108 on the helmet shell 105 in the area of the back of the head, which ensures that the helmet shell 105 does not hit the head 102 of the wearer of the protective helmet 100 in this area. The distance A shown is the smallest distance between the inside 106 of the helmet shell 105 and the head 102. In the exemplary embodiment shown, the distance A is at least 0.3 cm, in particular at least 0.7 cm, particularly preferably at least 1.3 cm.

Erfindungsgemäß wird das Kopfschutzsystem in dem dargestellten Zustand ohne Brandschutztuch getragen, falls der Träger sich aktuell nicht vor heißer Umgebungsluft schützen möchte und daher an einem Luftstrom durch den Luftweg 110 interessiert ist. Ein derartiger Luftstrom kann beispielsweise eine sich auf der Innenseite 106 der Helmschale 105 stauende Wärme von dem Träger wegführen. Weiterhin kann der Luftstrom eine Kühlung des Kopfes 102 des Trägers bewirken.According to the invention, the head protection system is worn in the state shown without a fire protection cloth if the wearer does not currently want to protect himself from hot ambient air and is therefore interested in an air flow through the airway 110 . Such an air flow can, for example, conduct heat accumulating on the inside 106 of the helmet shell 105 away from the wearer. Furthermore, the flow of air can cool the head 102 of the wearer.

Fig. 2 zeigt eine schematische Darstellung eines Brandschutztuches 200 gemäß dem ersten Ausführungsbeispiel des erfindungsgemäßen Kopfschutzsystems. 2 shows a schematic representation of a fire protection cloth 200 according to the first exemplary embodiment of the head protection system according to the invention.

Das Brandschutztuch 200 weist ein Befestigungsband 230 auf. Das Befestigungsband 230 ist starr ausgebildet. Starr ausgebildet ist das Befestigungsband 230 dadurch, dass es nicht in lateraler Richtung, also in Richtung der Ausdehnung des Befestigungsbandes 230, dehnbar ist. Vorliegend ist das Befestigungsband 230 aus einem Kunststoff hergestellt und kann in transversaler Richtung gebogen werden. Ein solches Biegen ist vorteilhaft, um bei der Lagerung des Brandschutztuches 200 nicht zu viel Platz einzunehmen und dennoch an einem Schutzhelm befestigbar zu sein. Dabei hat das Befestigungsband 230 eine Mehrzahl von starren Befestigungselementen 235, die jeweils dazu ausgebildet sind, in eine jeweilige Öffnung 120 des Befestigungsrings 125 einzugreifen und dadurch das Brandschutztuch 200 an dem Schutzhelm 100 lösbar zu befestigen. Vorliegend verfügen die Befestigungselemente 235 über einen jeweiligen Vorsprung 237, über den ein jeweiliges Befestigungselement 235 an einer jeweiligen Öffnung 120 befestigbar ist. Das Befestigungsband 230 in dem dargestellten Ausführungsbeispiel ist einteilig ausgebildet, wobei die beiden Enden im Bereich der Stirn des Kopfes 120 angeordnet werden. Entsprechend sind Aussparungen 240 in dem Brandschutztuch 200 für das Gesicht des Trägers in gegenüberliegenden Randbereichen des eigentlichen textilen Teils 250 des Brandschutztuches 200 angeordnet.The fire protection sheet 200 has a fastening strap 230 . The fastening strap 230 is rigid. The fastening strap 230 is rigid in that it cannot be stretched in the lateral direction, ie in the direction of expansion of the fastening strap 230 . Here, the fastening strap 230 is made of a plastic and can be bent in the transverse direction. Such bending is advantageous in order not to take up too much space when the fire protection sheet 200 is stored and still be able to be fastened to a protective helmet. The fastening strap 230 has a plurality of rigid fastening elements 235 which are each designed to engage in a respective opening 120 of the fastening ring 125 and thereby to fasten the fire protection cloth 200 to the protective helmet 100 in a detachable manner. In the present case, the fastening elements 235 have a respective projection 237, via which a respective fastening element 235 can be fastened to a respective opening 120. The fastening strap 230 in the exemplary embodiment shown is formed in one piece, the two ends being arranged in the area of the forehead of the head 120 . Correspondingly, recesses 240 are arranged in the fire protection cloth 200 for the wearer's face in opposite edge regions of the actual textile part 250 of the fire protection cloth 200 .

Das Befestigungsband 230 ist an das textile Teil 250 angenäht. In einem nicht dargestellten Ausführungsbeispiel erfolgt die Verbindung des Befestigungsbands an dem textilen Teil über eine Klebung.The fastening strap 230 is sewn to the textile part 250 . In an exemplary embodiment that is not shown, the fastening strap is connected to the textile part by means of an adhesive bond.

Die Mehrzahl von starren Befestigungselementen 235 ist derart auf die Struktur des Schutzhelms 100 abgestimmt, dass im befestigten Zustand die Mehrzahl von Öffnungen 120 derart durch die Befestigungselemente 235 ausgefüllt ist, dass der Luftweg durch die Mehrzahl von Öffnungen geschlossen ist.The plurality of rigid fasteners 235 is matched to the structure of the protective helmet 100 such that when fastened, the plurality of openings 120 are filled by the fasteners 235 such that the air path through the plurality of openings is closed.

In dem dargestellten Ausführungsbeispiel umfasst das Befestigungsband 230 genau vier starre Befestigungselemente 235. In einem nicht dargestellten Ausführungsbeispiel umfasst das Kopfschutzsystem mehr als vier Öffnungen, insbesondere mindestens sechs Öffnungen und eine entsprechende Anzahl an starren Befestigungselementen.In the exemplary embodiment shown, the fastening strap 230 comprises exactly four rigid fastening elements 235. In an exemplary embodiment which is not shown, the head protection system comprises more than four openings, in particular at least six openings and a corresponding number of rigid fastening elements.

Die starren Befestigungselemente 235 in dem dargestellten Ausführungsbeispiel sind im Wesentlichen rechteckig ausgebildet und sind dadurch besonders geeignet, die entsprechenden im Wesentlichen rechteckig ausgebildeten Öffnungen 120 an dem Befestigungsring 125 auszufüllen. Vorliegend erfolgt ein derartiges Ausfüllen durch ein Hindurchtreten eines jeweiligen Befestigungselements 235 durch eine dafür vorgesehene Öffnung 120 und ein entsprechendes Einrasten des Befestigungselements 235 in dieser Öffnung 120 durch den entsprechenden Vorsprung 237. Das jeweilige im Wesentlichen rechteckige, starre Befestigungselement 235 aus der Mehrzahl von Befestigungselementen hat eine Breite B2 von mindestens 0,3 cm, insbesondere mindestens 0,5 cm, besonders bevorzugt mindestens 1 cm. Weiterhin hat das jeweilige im Wesentlichen rechteckige starre Befestigungselemente 235 eine Höhe H2 von mindestens 0,3 cm, insbesondere mindestens 0,5 cm, besonders bevorzugt mindestens 1 cm.The rigid fastening elements 235 in the exemplary embodiment shown are of essentially rectangular design and are therefore particularly suitable for filling the corresponding essentially rectangular openings 120 on the fastening ring 125 . In the present case, such filling takes place by passing a respective fastening element 235 through an opening 120 provided for this purpose and correspondingly locking the fastening element 235 in this opening 120 by the corresponding projection 237. The respective substantially rectangular, rigid fastening element 235 from the plurality of fastening elements has a width B2 of at least 0.3 cm, in particular at least 0.5 cm, particularly preferably at least 1 cm. Furthermore, the respective essentially rectangular rigid fastening element 235 has a height H2 of at least 0.3 cm, in particular at least 0.5 cm, particularly preferably at least 1 cm.

Das Befestigungsband 230 ist mindestens 1 mm, insbesondere mindestens 1,5 mm dick.The fastening strap 230 is at least 1 mm thick, in particular at least 1.5 mm thick.

Der Schutzhelm 100 und das Brandschutztuch 200 aus Fig. 1 und Fig. 2 sind aufeinander abgestimmt und bilden ein gemeinsames erfindungsgemäßes Kopfschutzsystem. Im Rahmen der in den Figuren 3 bis 5 abgebildeten Ausführungsbeispiele werden Schutzhelm und Brandschutztuch in einem einander befestigten Zustand dargestellt, wobei ein vorderer Bereich der entsprechenden Helmschale des Schutzhelms jeweils verkürzt dargestellt ist, um die Befestigung des jeweiligen Brandschutztuches an dem jeweiligen Schutzhelm und die Lage der Mehrzahl von Öffnungen geeignet darstellen zu können.The safety helmet 100 and the fire protection cloth 200 off 1 and 2 are coordinated and form a common head protection system according to the invention.

Das Befestigungsband 430 des Brandschutztuches 460 ist an dem Befestigungsring 425 das Schutzhelms 470 über einen Einrastmechanismus befestigt. Der Einrastmechanismus wird durch die Kombination von starren Befestigungselementen 435 und die entsprechenden Öffnungen 420 gebildet. Das Einrasten erfolgt dabei über die an den drei starren Befestigungselementen 435 jeweils angeordneten Vorsprünge (nicht dargestellt). Damit liegt eine formschlüssige Verbindung und gleichzeitig eine kraftschlüssige Verbindung zwischen Brandschutztuch 460 und Schutzhelm 470 vor.The fastening strap 430 of the fire protection sheet 460 is fastened to the fastening ring 425 of the protective helmet 470 via a snap-in mechanism. The latching mechanism is formed by the combination of rigid fasteners 435 and the corresponding openings 420 . The latching takes place via the projections (not shown) arranged on each of the three rigid fastening elements 435 . There is thus a positive connection and at the same time a non-positive connection between the fire protection sheet 460 and the protective helmet 470 .

Weiterhin unterscheidet sich das Kopfschutzsystem 400 von dem in Fig. 3 dargestellten Kopfschutzsystem 300 dadurch, dass neben der Befestigung über die starren Befestigungselementen eine Mehrzahl von Befestigungsteilen 480 an dem Brandschutztuch 460 angeordnet sind, über die das Brandschutztuch 460 zusätzlich mit dem Schutzhelm 470 lösbar verbunden ist. Die Mehrzahl von Befestigungsteilen 480 umfasst zwei Befestigungsteile, die von der Innenseite 406 der Helmschale 405 gegen den Befestigungsring 425 gepresst werden, um mit entsprechend ausgebildeten Gegenteilen 485 des Befestigungsringes 425 eine lösbare Verbindung zwischen Brandschutztuch 460 und Schutzhelm 470 zu bilden. Durch diese zusätzliche Verbindung ist in dem dargestellten Ausführungsbeispiel das Brandschutztuch 460 besonders zuverlässig und sicher mit dem Schutzhelm 470 verbunden.Furthermore, the head protection system 400 differs from that in 3 head protection system 300 shown in that, in addition to the attachment via the rigid attachment elements, a plurality of attachment parts 480 are arranged on the fire protection cloth 460, via which the fire protection cloth 460 is also detachably connected to the protective helmet 470. The plurality of fastening parts 480 comprises two fastening parts which are pressed against the fastening ring 425 from the inside 406 of the helmet shell 405 in order to form a detachable connection between the fire protection cloth 460 and the protective helmet 470 with the correspondingly designed counterparts 485 of the fastening ring 425 . Due to this additional connection, the fire protection sheet 460 is particularly reliably and securely connected to the protective helmet 470 in the exemplary embodiment shown.

Fig. 5 zeigt eine schematische Darstellung eines vierten Ausführungsbeispiels des erfindungsgemäßen Kopfschutzsystems 500. figure 5 shows a schematic representation of a fourth exemplary embodiment of the head protection system 500 according to the invention.

Das Kopfschutzsystem 500 unterscheidet sich von dem in Fig. 3 dargestellten Kopfschutzsystem 300 dadurch, dass das Brandschutztuch 560 im befestigten Zustand auf der vom Kopf des Trägers wegweisende Seite des Befestigungsrings 525 befestigt ist. Dabei werden die starren Befestigungselemente 535 des Befestigungsbands 530 nicht wie in den vorhergehenden Ausführungsbeispielen durch eine jeweilige Öffnung des Befestigungsrings 525 hindurch gesteckt. Die starren Befestigungselemente 535 werden in dem dargestellten Ausführungsbeispiel über eine jeweilige Schiene 590 an dem Befestigungsring 525 gehalten. Eine wirksame Befestigung gegenüber auf das Brandschutztuch 560 wirkenden Zugkräften wird durch eine zusätzliche Befestigung des Brandschutztuches 560 an dem Schutzhelm 570 über entsprechende Befestigungsteile 580 ermöglicht. Diese entsprechenden Befestigungsteile 580 verfügen über Vorsprünge, die in Richtung des Kopfes durch entsprechende Gegenteile (nicht dargestellt) des Befestigungsrings 525 gepresst und/oder gesteckt werden. Auch andere bekannte Steckverbindungen, Klemmverbindungen oder über ein Einrasten realisierte Verbindungen können als zusätzliche Verbindung für das Befestigen des Brandschutztuches 560 an dem Schutzhelm 570 verwendet werden.The head protection system 500 differs from that in 3 head protection system 300 shown in that the fire protection cloth 560 is fastened in the fastened state on the side of the fastening ring 525 pointing away from the wearer's head. The rigid fastening elements 535 of the fastening strap 530 are not inserted through a respective opening of the fastening ring 525 as in the previous exemplary embodiments. In the exemplary embodiment shown, the rigid fastening elements 535 are held on the fastening ring 525 via a respective rail 590 . An effective attachment against tensile forces acting on the fire protection cloth 560 is made possible by an additional attachment of the fire protection cloth 560 to the protective helmet 570 via corresponding attachment parts 580 . These respective fasteners 580 have protrusions that are pressed and/or pinched toward the head by corresponding counterparts (not shown) of the fastener ring 525 . Other known plug-in connections, clamp connections or connections implemented by snapping in can also be used as an additional connection for fastening the fire protection cloth 560 to the protective helmet 570 .

Die Mehrzahl von Öffnungen 520 wird im befestigten Zustand des Brandschutztuches 560 komplett geschlossen. In dem dargestellten Ausführungsbeispiel wird durch das erfindungsgemäße Schließen der Mehrzahl von Öffnungen 520 der Luftweg zwischen Schutzhelm 570 und Kopf komplett geschlossen. Dies wird auch durch den textilen Teil 550 des Brandschutztuches 560 erreicht, der im Bereich der Stirn an dem Kopf des Trägers anliegt. In den vorhergehenden Ausführungsbeispielen lag ebenfalls eine komplette Schließung der Öffnungen durch die Befestigungselemente vor. In einem nicht dargestellten Ausführungsbeispiel wird eine jeweilige Öffnung des Befestigungsrings nur teilweise durch das entsprechende Befestigungselement geschlossen.The plurality of openings 520 is completely closed when the fire protection sheet 560 is in the fastened state. In the exemplary embodiment shown, the air path between the protective helmet 570 and the head is completely closed by the closing of the plurality of openings 520 according to the invention. This is also achieved by the textile part 550 of the fire protection cloth 560, which rests against the head of the wearer in the area of the forehead. In the previous exemplary embodiments, the openings were also completely closed by the fastening elements. In an embodiment that is not shown, a respective opening of the fastening ring is only partially closed by the corresponding fastening element.

Anders als in den vorhergehenden Ausführungsbeispielen stimmen bei dem Kopfschutzsystem 500 nicht die Form der Mehrzahl von Öffnungen 520 und die Form der starren Befestigungselementen 535 überein. Die starren Befestigungselementen 535 sind rechteckig geformt und die Mehrzahl der Öffnungen 520 ist oval geformt. Hierdurch kann in dem dargestellten Ausführungsbeispiel ein besonders sicheres Schließen der Öffnungen 520 durch die starren Befestigungselementen 535 ermöglicht werden.Unlike the previous exemplary embodiments, the shape of the plurality of openings 520 and the shape of the rigid attachment elements 535 do not match in the head protection system 500 . The rigid fasteners 535 are rectangular in shape and the majority of the openings 520 are oval in shape. As a result, in the exemplary embodiment shown, the openings 520 can be closed particularly securely by the rigid fastening elements 535 .
