Abstract

The helmet includes a helmet shell (3) that surrounds the user's head except the face area of the user, a chin guard that surrounds lower parts of the user's face area, and a visor (4) pivotally positioned on helmet shell and on the chin guard to form an opening for the face between helmet shell and chin guard. The chin guard has two sections movably mounted on helmet shell. Each chin guard section is pivotally arranged on helmet shell. The pivotable arrangement of the chin guard sections takes place using flexible plate (2) which connects the helmet shell to corresponding chin guard sections.

Description

Die Erfindung betrifft einen Schutzhelm mit einer Helmschale, die beim Gebrauch den Kopf des Trägers mit Ausnahme des Gesichtsbereiches zumindest teilweise umgibt, einem Kinnbügel, der beim Gebrauch die unteren Teile des Gesichtsbereiches des Trägers umspannt, sowie einem vorzugsweise schwenkbar an der Helmschale angeordneten Visier zum Abdecken der Gesichtsfeldöffnung zwischen Helmschale und Kinnbügel, wobei der Kinnbügel zwei relativ zueinander bewegbare Abschnitte aufweist, gemäß dem Oberbegriff von Anspruch 1.The invention relates to a protective helmet with a helmet shell, which in use at least partially surrounds the head of the wearer with the exception of the facial area, a chin guard which in use covers the lower parts of the face area of the wearer, and a visor, preferably pivotally mounted on the helmet shell, for covering the visual field opening between the helmet shell and the chin guard, the chin guard having two sections movable relative to one another, according to the preamble of claim 1.

Derartige Schutzhelme mildern oder verhindern Verletzungen im Schädelbereich des Helmträgers, insbesondere bei Motorradunfällen. Dabei können mehrere Ausführungsvarianten unterschieden werden.
In der EP 0 433 182 wird etwa ein Helm mit zwei relativ zueinander bewegbaren Kinnbügelabschnitten beschrieben, die verschiebbar an der Helmschale gelagert sind. Bei diesem Helm lässt sich bei einem bloße Verschieben der Kinnbügelabschnitte in Richtung des Helminneren die Öffnung des Helms nach unten aber nicht sehr erweitern. Außerdem ist keine vorspannung weder in die geöffnete Position, noch in die geschlossene Position der Kinnbügelabschnitte verwirklichbar. Ein solcher Helm ist außerdem technisch nur aufwändig herzustellen, und lässt auch keine Gelenkverbindung zwischen den beiden Kinnbügelabschnitten zu. Dadurch kann aber auch keine Synchronisation der Kinnbügelabschnitte in ihrem jeweiligen Bewegungsweg erfolgen.Such helmets mitigate or prevent injuries in the skull of the helmet wearer, especially in motorcycle accidents. Several variants can be distinguished.
In the EP 0 433 182 For example, a helmet is described with two chin strap sections which are movable relative to one another and which are displaceably mounted on the helmet shell. In this helmet, the opening of the helmet downwards but not much can be extended in a mere displacement of the chin guard sections in the direction of the helmet interior. In addition, no bias in either the open position, or in the closed position of the chin guard sections feasible. Such a helmet is also technically difficult to produce, and also allows no joint connection between the two chin guard sections. As a result, however, no synchronization of the chin guard sections can take place in their respective movement path.

Ein Schutzhelm mit zwei relativ zueinander bewegbaren Kinnbügelabschnitten ist auch in der DE 41 33 223 beschrieben.A protective helmet with two chin strap sections movable relative to each other is also in the DE 41 33 223 described.

Des Weiteren sind etwa Helme bekannt, bei denen der Gesichtsbereich offen ist (sog. "Jet-Helme"). Diese Helme bieten zwar einen Frischluft-Vorteil, der sich aber bei Regen und Kälte nachteilig auswirkt. Außerdem sind Gesicht und Kinnpartie bei einem Unfall nur unzulänglich geschützt.Furthermore, helmets are known in which the facial area is open (so-called "jet helmets"). Although these helmets offer a fresh air advantage, but it has a negative impact in rain and cold. In addition, face and chin are protected inadequately in an accident.

Crosshelme finden insbesondere im sportlichen Zweiradbereich Einsatz und weisen ebenfalls eine verhältnismäßig große Visieröffnung auf, um die bei körperlicher Anstrengung wichtige Luftzufuhr sicher zu stellen. Diese Helme weisen aber im Gegensatz zu Jet-Helmen einen stabilen Kinnbügel auf, um bei den mitunter häufigen Stürzen ausreichend Schutz zu bieten.Crosshelms are used especially in the sporty two-wheeler sector and also have a relatively large Visor opening on to ensure the important in physical exertion air supply. These helmets, in contrast to jet helmets, have a sturdy chin guard to provide sufficient protection against the sometimes frequent falls.

Sogenannte Klapp- bzw. Systemhelme weisen einen einteiligen, massiven Kinnbügel auf, an den zumeist auch das Visier angeformt ist. Der Kinnbügel lässt sich über eine im Wesentlichen horizontale Schwenkachse nach oben klappen, sodass das Auf- und Absetzen erleichtert wird. Diese Helmtypen erleichtern zwar den Einstieg in den Helm, da der Helm mit aufgeklapptem Kinnbügel angelegt wird, da aber der Kinnbügel nur horizontal nach unten schwenkt, bieten sie keine zusätzliche Passgenauigkeit im Kinnbereich. Helme dieser Art können auch nicht mit Brille auf- oder abgesetzt werden.So-called folding or system helmets have a one-piece, solid chin guard on which the visor is usually molded. The chin guard can be folded upwards over a substantially horizontal pivot axis, so that setting up and setting down is facilitated. Although these helmet types make it easier to get into the helmet because the helmet is put on with the chin strap open, but since the chin guard pivots only horizontally downwards, they offer no additional accuracy of fit in the chin area. Helmets of this kind can not be put on or taken off with glasses.

Gemäß einer weiteren Ausführungsvariante ist eine Helmschale vorgesehen, die beim Gebrauch den Kopf des Trägers mit Ausnahme des Gesichtsbereiches annähernd vollständig umgibt, einem Kinnbügel, der beim Gebrauch die unteren Teile des Gesichtsbereiches des Trägers umspannt, sowie einem vorzugsweise schwenkbar an der Helmschale angeordneten Visier zum Abdecken der Gesichtsfeldöffnung zwischen Helmschale und Kinnbügel. Die Befestigung am Kopf des Trägers erfolgt über einen Kinnriemen, der im Kinnbereich des Trägers nach dem Anlegen des Helms gespannt wird. Helme dieser Art (sog. "Integralhelme") sind weit verbreitet, weisen aber den Nachteil auf, dass das An- und Ablegen unpraktisch ist. Insbesondere bei Unfällen kann die schwierige Abnehmbarkeit des Helms mitunter auch zu gefährlichen Situationen führen, etwa bei Halsverletzungen.According to a further embodiment variant, a helmet shell is provided which, in use, approximately completely surrounds the head of the wearer with the exception of the face region, a chin guard which in use covers the lower parts of the face region of the wearer, and a visor which is preferably pivotably arranged on the helmet shell for covering the visual field opening between the helmet shell and the chin guard. The attachment to the head of the wearer via a chin strap, which is stretched in the chin area of the wearer after putting on the helmet. Helmets of this kind (so-called "full-face helmets") are widespread, but have the disadvantage that putting on and taking off is impractical. In particular, in accidents, the difficult removability of the helmet can sometimes lead to dangerous situations, such as neck injuries.

Alle genannten Helmtypen weisen außerdem den Nachteil auf, dass zwar stets unterschiedliche Helmgrößen angeboten werden, um für unterschiedliche Kopfgrößen das jeweils bestpassende Modell auszuwählen, es erweist sich aber in der Praxis, dass auf diese Weise nur bedingt ein optimaler Sitz des Helms erreicht werden kann. In der Praxis steht der Konsument somit zumeist vor der Wahl zwischen einem Helm, der zwar guten Sitz bietet, aber schwer auf- und abzusetzen ist, oder einen Helm, der leicht auf- und absetzbar ist, aber nur schlecht sitzt. Zudem bietet der bei Helmen dieser Art zur Fixierung des Helms am Kopf des Trägers zumeist notwendige Kinnriemen ohnehin bereits unzulänglichen Halt, insbesondere im Kiefer- und Nackenbereich, was sich bei schlechtem Sitz des Helms somit noch stärker auswirkt. Dieser Nachteil wird insbesondere bei höheren Geschwindigkeiten bemerkbar, wo zusätzliche Winddruckkräfte wirken und den Helm hochschieben können. Zudem können aufgrund des mangelnden Abschlusses zwischen Helm und dem vorderen Halsbereich unter den Helm eintretende Luftströmungen den Fahrkomfort beeinträchtigen, da sie unangenehme Windgeräusche und Kälte verursachen.All mentioned helmet types also have the disadvantage that although always different helmet sizes are offered to select the best fitting model for different head sizes, but it turns out in practice that in this way only an optimal fit of the helmet can be achieved. In practice, the consumer is thus usually faced with the choice between a helmet that offers a good fit, but difficult to put on and off, or a helmet that is easy to put on and off, but only badly. In addition, the helmets of this type for fixing the helmet on the head of the wearer usually necessary chin strap anyway already inadequate grip, especially in the jaw and neck area, which thus has even worse effect in bad seat of the helmet. This disadvantage is particularly noticeable at higher speeds, where additional wind pressure forces act and can push up the helmet. In addition, due to the lack of completion between the helmet and the front neck area under the helmet entering air currents can affect the ride comfort, as they cause unpleasant wind noise and cold.

Kinnriemen haben auch den Nachteil, dass sie mitunter schwer zu handhaben sind, insbesondere beim Tragen von Handschuhen. Sie können auch nur schwer mit einer Hand bedient werden. Zudem werden zahlreiche Verschlusssysteme für den Kinnriemen angeboten, deren Bedienung bei Unkenntnis mitunter Schwierigkeiten bereitet. In der Praxis zeigt sich tatsächlich, dass etwa in Unfallsituationen den Sanitätskräften das Öffnen von Verschlusssystemen der Kinnriemen schwer fällt und wertvolle Zeit in Anspruch nimmt.Chin straps also have the disadvantage that they are sometimes difficult to handle, especially when wearing gloves. They are also difficult to operate with one hand. In addition, numerous closure systems are offered for the chin strap, whose operation sometimes causes difficulties in ignorance. In practice, it is actually shown that in emergency situations, for example, the opening of the chin strap locking systems is difficult and time-consuming for the medical staff.

Es ist daher das Ziel der Erfindung einen Schutzhelm zu verwirklichen, der leicht aufsetzbar und abnehmbar ist, sowie besseren Halt bietet, insbesondere im Kiefer- und Nackenbereich. Dadurch soll vor allem auch ein Abgleiten des Helmes über den Hinterkopf, etwa im Zuge von Unfallsituationen, vermieden werden. In der für das Erfindungsgebiet gängigen Ausdrucksweise wird dies auch als "Abstreifverhalten" bezeichnet, das somit beim erfindungsgemäßen Schutzhelm verbessert werden soll. Die Erfindung soll außerdem die Verwirklichung besserer aerodynamischer und aeroakustischer Eigenschaften, sowie einen besseren Schutz gegen Wind, Schmutz und Kälte ermöglichen.It is therefore the object of the invention to realize a protective helmet which is easy to put on and detach, and offers better grip, especially in the jaw and neck area. As a result, especially a slipping of the helmet over the back of the head, for example in the course of accident situations, are avoided. In the usual expression for the field of the invention this is also referred to as "stripping behavior", which is thus to be improved in the protective helmet according to the invention. The invention should also allow the realization of better aerodynamic and aeroacoustic properties, as well as better protection against wind, dirt and cold.

Diese Ziele werden durch die Merkmale von Anspruch 1 oder 2 erreicht. Anspruch 1 und 2 beziehen sich jeweils auf einen Schutzhelm mit einer Helmschale, die beim Gebrauch den Kopf des Trägers mit Ausnahme des Gesichtsbereiches zumindest teilweise umgibt, einem Kinnbügel, der beim Gebrauch die unteren Teile des Gesichtsbereiches des Trägers umspannt, sowie einem vorzugsweise schwenkbar an der Helmschale angeordneten Visier zum Abdecken der Gesichtsfeldöffnung zwischen Helmschale und Kinnbügel, wobei der Kinnbügel zwei relativ zueinander bewegbare Abschnitte aufweist. Erfindungsgemäß ist gemäß Anspruch 1 vorgesehen, dass jeder der beiden Kinnbügelabschnitte an der Helmschale schwenkbar angeordnet ist, und die schwenkbare Anordnung der Kinnbügelabschnitte an der Helmschale jeweils mithilfe eines flexiblen Plattenelements erfolgt, das die Helmschale mit dem jeweiligen Kinnbügelabschnitt verbindet. Erfindungsgemäß ist gemäß Anspruch 2 vorgesehen, dass die beiden Kinnbügelabschnitte in ihren jeweils oberen Abschnitten über eine Gelenkverbindung miteinander verbunden sind. Dadurch erfolgt stets ein synchrones Schließen der beiden Kinnbügelabschnitte, auch wenn mit den Händen auf die beiden Kinnbügelabschnitte unterschiedlicher Schließdruck ausgeübt wird. Insbesondere kann durch diese Maßnahme das Schließen der Kinnbügelabschnitte auch einhändig erfolgen.These objects are achieved by the features of claim 1 or 2. Claim 1 and 2 each relate to a protective helmet with a helmet shell, which in use the head of the Carrier with the exception of the facial area at least partially surrounds a chin guard, which spans in use the lower parts of the face region of the wearer, and a preferably pivotally mounted on the helmet shell visor for covering the visual field opening between the helmet shell and chin guard, wherein the chin guard two relatively movable sections having. According to the invention it is provided according to claim 1, that each of the two chin guard sections is pivotally mounted on the helmet shell, and the pivotable arrangement of the chin guard sections on the helmet shell takes place in each case by means of a flexible plate member which connects the helmet shell with the respective chin strap section. According to the invention it is provided according to claim 2, that the two chin strap sections are connected in their respective upper sections via a hinge connection. As a result, there is always a synchronous closing of the two chin guard sections, even if different closing pressures are exerted with the hands on the two chin guard sections. In particular, by this measure, the closing of the chin guard sections can also be done with one hand.

Durch die schwenkbare Anordnung der Kinnbügelabschnitte ist es zunächst möglich, vor dem Aufsetzen und Abnehmen des Helms die Helmöffnung zu erweitern, wodurch das Aufsetzen und Abnehmen erleichtert wird. Beide Kinnbügelabschnitte werden dabei in der Regel in einer Weise schwenkbar angeordnet sein, dass jeder der beiden Kinnbügelabschnitte beim Öffnen um jeweils unterschiedliche Achsen nach unten und außen verschwenkt, sodass sich die beiden Kinnbügelabschnitte beim Öffnen voneinander entfernen. Beim Schließen der Kinnbügelabschnitte bewegen sie sich wieder aufeinander zu, wodurch sich die Helmöffnung verkleinert.Due to the pivotable arrangement of the chin guard sections, it is initially possible to expand the helm opening prior to putting on and removing the helmet, whereby the placement and removal is facilitated. Both chin guard sections will generally be arranged to be pivotable in a manner such that each of the two chin guard sections pivots downwards and outwards about respective different axes so that the two chin guard sections move away from one another when opening. When closing the chin guard sections, they move towards each other again, which reduces the helmet opening.

Es ist aber aufgrund der erfindungsgemäßen Maßnahmen auch möglich, die Kinnbügelabschnitte konstruktiv so zu gestalten, dass nach dem Aufsetzen des Helms die Helmöffnung noch zusätzlich verkleinert wird, wodurch sich der Halt vor allem im Kinnbereich deutlich verbessert, da durch die Verschwenkbarkeit der Kinnbügelabschnitte eine hinreichend große Helmöffnung für das Auf- und Absetzen des Helms gewährleistet ist. So kann etwa gemäß Anspruch 3 vorgesehen sein, dass die beiden Kinnbügelabschnitte jeweils in ihrem unteren Bereich eine seitlich in Richtung des Helminneren abstehende Kinnschutzfläche aufweisen. Dadurch wird beim Schließen der Kinnbügelabschnitte die Helmöffnung zusätzlich verringert, wodurch nicht nur der Halt verbessert wird, sondern auch bessere aerodynamische und aeroakustische Eigenschaften des Helms, sowie besserer Schutz gegen Wind, Schmutz und Kälte ermöglicht werden, wie noch näher ausgeführt werden wird.However, it is also possible due to the inventive measures, the chin guard sections structurally designed so that after putting on the helmet, the helmet opening is additionally reduced, thereby improving the grip, especially in the chin area significantly, as by the pivotability the chin guard sections a sufficiently large helmet opening for the raising and lowering of the helmet is guaranteed. For example, according to claim 3, it may be provided that the two chin guard sections each have, in their lower area, a chin guard surface projecting laterally in the direction of the helmet interior. As a result, the helmet opening is additionally reduced when closing the chin guard sections, whereby not only the grip is improved, but also better aerodynamic and aeroacoustic properties of the helmet, as well as better protection against wind, dirt and cold are made possible, as will be explained in more detail.

Eine besonders vorteilhafte Ausführungsform für die Kinnbügelabschnitte ist in Anspruch 4 vorgeschlagen. Anspruch 4 sieht vor, dass die Kinnbügelabschnitte an ihrem der Helmschale zugewandten Ende jeweils einen Befestigungsbereich aufweisen, und an ihrem der Helmschale abgewandten Ende jeweils einen Schließbereich mit einer Schließfläche, wobei die beiden Schließflächen in einer Öffnungsposition der beiden Kinnbügelabschnitte voneinander beabstandet sind, und in einer durch Verschwenken der beiden Kinnbügelabschnitte erreichbaren Schließposition aneinander anliegen.A particularly advantageous embodiment of the chin guard sections is proposed in claim 4. Claim 4 provides that the chin guard sections each have a fastening region at their end facing the helmet shell, and at their end facing away from the helmet shell each have a closing region with a closing surface, wherein the two closing surfaces are spaced apart in an opening position of the two chin strap sections, and in one abut each other by pivoting the two chin guard sections achievable closing position.

Vorteilhaft ist dabei das Merkmal von Anspruch 5, dem zu Folge im Bereich der Schließflächen ein Schließmechanismus angeordnet ist, der die beiden Kinnbügelabschnitte in ihrer Schließposition aneinander räumlich fixiert. Der Schließmechanismus kann im Bereich der Schließflächen etwa an den nach unten orientierten Flächen angeordnet sein, und etwa als Schnalle ausgeführt sein.Advantageously, the feature of claim 5, which is arranged as a result in the region of the closing surfaces, a closing mechanism which fixes the two chin strap sections in their closed position to each other spatially. The closing mechanism may be arranged in the region of the closing surfaces approximately at the downwardly oriented surfaces, and be designed as a buckle.

Anspruch 6 sieht vor, dass eine der Schließflächen eine Nut, und die andere Schließfläche eine der Nut zugeordnete Feder aufweist, wobei in der Schließposition Nut und Feder ineinander greifen. Dadurch können Scherkräfte der beiden Kinnbügelabschnitte im Falle eines Aufpralls besser aufgenommen und die Belastung der Gelenkverbindung und des Schließmechanismus verringert werden. So kann auch das ordnungsgemäße Funktionieren des Schließmechanismus im Fall eines Unfalls und der dadurch verursachten Belastungen auf die Kinnbügelabschnitte sichergestellt werden.Claim 6 provides that one of the closing surfaces has a groove, and the other closing surface has a tongue associated with the groove, wherein engage in the closed position tongue and groove. As a result, shear forces of the two chin strap sections can be better absorbed in the event of an impact and the load on the articulated connection and the locking mechanism can be reduced. So can the proper functioning of the locking mechanism in the case an accident and the resulting stress on the chin guard sections are ensured.

Sind die beiden Kinnbügelabschnitte gemäß Anspruch 7 in ihre Öffnungsposition vorgespannt, so schwenken die beiden Kinnbügelabschnitte etwa nach dem Öffnen des Schließmechanismus automatisch in die Öffnungsposition. Ist etwa ein flexibles Plattenelement vorgesehen, so kann die Vorspannung dadurch erreicht werden, indem sich in der Öffnungsposition das Plattenelement in seiner spannungsfreien Lage befindet, während es im Zuge der Schließbewegung in Spannung versetzt wird.If the two chin strap sections are prestressed into their open position according to claim 7, then the two chin strap sections automatically pivot into the open position approximately after the opening mechanism has been opened. If, for example, a flexible plate element is provided, then the prestressing can be achieved by the plate element being in its tension-free position in the open position, while it is set in tension during the closing movement.

Gemäß Anspruch 8 ist vorgesehen, dass der Befestigungsbereich der beiden Kinnbügelabschnitte jeweils mit einer der Helmschale zugewandten Seitenfläche abschließt, die in der Schließposition der Kinnbügelabschnitte an einer Stützfläche der Helmschale anliegt, und in der Öffnungsposition der Kinnbügelabschnitte von der Stützfläche beabstandet ist. Durch das Abstützen der Kinnbügelabschnitte an der Helmschale in der Schließposition wird besserer Schutz bei Kräften, die von unten auf die Kinnbügelabschnitte wirken, gewährleistet. Ist insbesondere gemäß Anspruch 9 vorgesehen, dass die Seitenfläche des Befestigungsbereiches der Kinnbügelabschnitte und die Stützfläche der Helmschale jeweils stufenförmig ausgebildet sind, wobei in der Schließposition der Kinnbügelabschnitte die stufenförmigen Abschnitte ineinander greifen, können wiederum Scherkräfte zwischen Kinnbügelabschnitt und Helmschale besser aufgenommen werden.According to claim 8, it is provided that the fastening region of the two chin strap sections terminates in each case with a side surface facing the helmet shell, which abuts against a support surface of the helmet shell in the closed position of the chin strap sections and is spaced from the support surface in the opening position of the chin strap sections. By supporting the chin strap sections on the helmet shell in the closed position, better protection is ensured for forces acting from below on the chin strap sections. In particular, it is provided according to claim 9 that the side surface of the attachment region of the chin guard sections and the support surface of the helmet shell are each formed step-shaped, wherein in the closed position of the chin guard sections the step-shaped sections interlock, again shear forces between the chin guard section and helmet shell can be better absorbed.

Gemäß Anspruch 10 ist die Kinnschutzfläche auf ihrer dem Helminneren zugewandten Seite mit einer abnehmbaren Polsterung versehen. Durch die Abnehmbarkeit können etwa Polsterungen mit unterschiedlicher Dicke eingesetzt werden, sodass der Helm besser auf unterschiedliche Kopfgrößen abgestimmt werden kann. Der Sitz des Helmes wird dadurch verbessert. Außerdem kann die abnehmbare Polsterung auch leichter gereinigt werden.According to claim 10, the chin protection surface is provided on its inner side facing the helmet with a removable padding. The removability can be used as padding with different thicknesses, so that the helmet can be better matched to different head sizes. The seat of the helmet is thereby improved. In addition, the removable padding can also be cleaned more easily.

Anspruch 11 sieht vor, dass die Seitenfläche des Befestigungsbereiches entlang ihrer Längserstreckung über eine Abschlussfläche stumpf in die Kinnschutzfläche übergeht, und sich die Abschlussfläche in der Schließposition der Kinnbügelabschnitte auf einer Halteschulter der Helmschale abstützt. Dadurch werden Kräfte, die frontal auf die Kinnbügelabschnitte wirken, vom Helm besser aufgenommen.Claim 11 provides that the side surface of the attachment region merges bluntly into the chin protection surface along its longitudinal extent via a termination surface, and the termination surface in the closed position of the chin guard sections is supported on a retaining shoulder of the helmet shell. As a result, forces acting frontally on the chin guard sections are better absorbed by the helmet.

Werden außerdem gemäß Anspruch 12 die beiden Kinnbügelabschnitte in ihrer Schließposition vom Visier übergriffen oder liegen an der Unterkante des Visiers an, so können die Kinnbügelabschnitte unabhängig vom Visier geöffnet und geschlossen werden.In addition, according to claim 12, the two chin guard sections are overlapped in their closed position by the visor or lie against the lower edge of the visor, so the chin guard sections can be opened and closed independently of the visor.

Zunächst wird auf die Fig. 1 Bezug genommen, die eine perspektivische Seitenansicht einer Ausführungsform eines erfindungsgemäßen Schutzhelms mit einer Helmschale 3 und Kinnbügelabschnitten 1a,1b (in der Fig. 1 ist nur der Kinnbügelabschnitt 1a sichtbar) zeigt, wobei sich letztere in ihrer geschlossenen Position befinden. Gemäß der gezeigten Ausführungsform sind die Kinnbügelabschnitte 1a,1b jeweils über ein flexibles Plattenelement 2 an der Helmschale 3 befestigt. Das Plattenelement 2 ist aus einem dauerhaft flexiblen, bruch- und reißfesten Material, etwa POM (Polyoxymethylen/Polyacetal) oder PC, gefertigt, und ist jeweils an der Außenfläche der Helmschale 3 durch eine Klebe-, Niet- oder Klippverbindung befestigt. Die Fig. 1 zeigt etwa eine Befestigung mithilfe von Nietverbindungen 5. Vorzugsweise können im Interesse einer besseren Aerodynamik die Plattenelemente 2 auch in der Helmschale 3 versenkt sein, sodass sich eine stufenfreie Außenfläche ergibt. Vorzugsweise ist an der Helmschale 3 auch ein Visier 4 schwenkbar angeordnet. Im Inneren der Helmschale 3 ist außerdem in der Regel eine Polsterung 12 vorgesehen.First, on the Fig. 1 Reference is made, which is a side perspective view of an embodiment of a protective helmet according to the invention with a helmet shell 3 and chin strap sections 1a, 1b (in the Fig. 1 only the chin guard portion 1a is visible), the latter being in their closed position. According to the embodiment shown, the chin guard sections 1a, 1b are each fastened to the helmet shell 3 via a flexible plate element 2. The plate element 2 is made of a permanently flexible, break-resistant and tear-resistant material, such as POM (polyoxymethylene / polyacetal) or PC, and is in each case attached to the outer surface of the helmet shell 3 by an adhesive, rivet or clip connection. The Fig. 1 For example, in the interest of better aerodynamics, the plate elements 2 can also be countersunk in the helmet shell 3, so that a step-free outer surface results. Preferably, a visor 4 is pivotally mounted on the helmet shell 3. In the interior of the helmet shell 3, a padding 12 is also provided as a rule.

Die Plattenelemente 2 sind über die Helmschale 3 und die jeweiligen Kinnbügelabschnitte 1a,1b so abgewickelt, dass sich bei den Schwenkbewegungen der Kinnbügelabschnitte 1a,1b nur parallele Spannungslinien normal zur Schwenkachse einstellen. Somit unterbleiben Verformungen der Plattenelemente 2, die nicht der Führung der Kinnbügelabschnitte 1a,1b dienen. Dadurch verringert sich die Materialbeanspruchung der Plattenelemente 2.The plate elements 2 are unwound via the helmet shell 3 and the respective chin strap sections 1a, 1b in such a way that only parallel tension lines normal to the pivot axis are set during the pivoting movements of the chin strap sections 1a, 1b. Thus, deformations of the plate elements 2 that do not serve to guide the chin guard sections 1a, 1b are omitted. As a result, the material stress of the plate elements 2 decreases.

Außerdem werden die Befestigungselemente 5 zwischen Plattenelement 2 und Helmschale 3 bzw. Kinnbügelabschnitt 1a,1b weniger belastet. Vorzugsweise sind die beiden Kinnbügelabschnitte 1a, 1b in ihre Öffnungsposition vorgespannt. Eine solche Vorspannung kann dadurch erreicht werden, indem sich in der Öffnungsposition das Plattenelement 2 in seiner spannungsfreien Lage befindet, während es im Zuge der Schließbewegung in Spannung versetzt wird. Es sind aber auch andere Ausführungsvarianten einer schwenkbaren Anordnung der Kinnbügelabschnitte 1a,1b an der Helmschale 3 denkbar, sofern sie eine Verschwenkbarkeit der Kinnbügelabschnitte 1a,1b zur Vergrößerung der Helmöffnung im Zuge des Übergangs von der Schließposition in die Öffnungsposition sicherstellen, und eine sichere Befestigung der Kinnbügelabschnitte 1a,1b an der Helmschale 3 garantieren.In addition, the fasteners 5 between plate member 2 and helmet shell 3 and chin strap section 1a, 1b less loaded. Preferably, the two chin guard portions 1a, 1b are biased in their open position. Such biasing can be achieved by the plate member 2 is in its tension-free position in the open position, while it is placed in the course of the closing movement in tension. But there are also other embodiments of a pivotable arrangement of the chin guard sections 1 a, 1 b on the helmet shell 3 conceivable, provided that they ensure pivotability of the chin guard sections 1 a, 1 b to increase the helmet opening in the course of the transition from the closed position to the open position, and secure attachment Guarantee chin strap sections 1a, 1b on the helmet shell 3.

Beide Kinnbügelabschnitte 1a,1b werden in der Regel in einer Weise schwenkbar angeordnet sein, dass jeder der beiden Kinnbügelabschnitte 1a,1b beim Öffnen um jeweils unterschiedliche Achsen nach unten und außen verschwenkt, sodass sich die schwerpunkte der beiden Kinnbügelabschnitte 1a,1b beim Öffnen voneinander entfernen. Beim Schließen der Kinnbügelabschnitte 1a, 1b bewegen sie sich wieder aufeinander zu, wodurch sich die Helmöffnung verkleinert. Die durch Helmschale 3, Kinnbügelabschnitte 1a,1b und Plattenelement 3 definierte Schwenkachse ist somit jeweils schräg orientiert, in Bezug auf die Fig. 1 verläuft sie etwa von links unten nach rechts oben.Both chin guard sections 1a, 1b will generally be arranged to be pivotable in a manner such that each of the two chin guard sections 1a, 1b pivots downwards and outwards on respective different axes during opening, so that the centers of gravity of the two chin bar sections 1a, 1b move away from one another during opening , When closing the chin guard sections 1a, 1b, they move toward each other again, whereby the helmet opening is reduced. The pivot axis defined by the helmet shell 3, chin guard sections 1a, 1b and plate element 3 is thus oriented obliquely with respect to each Fig. 1 it runs from the bottom left to the top right.

Die Fig. 2 zeigt eine perspektivische Seitenansicht der Ausführungsform von Fig. 1 in einer offenen Position der Kinnbügelabschnitte 1a, 1b. Wie bereits erwähnt wurde, ist es aufgrund der erfindungsgemäßen Maßnahmen möglich, die Kinnbügelabschnitte 1a,1b konstruktiv so zu gestalten, dass nach dem Aufsetzen des Helms die Helmöffnung noch zusätzlich verkleinert wird, wodurch sich der Sitz des Helms vor allem im Kinnbereich deutlich verbessert, da durch die Verschwenkbarkeit der Kinnbügelabschnitte eine hinreichend große Helmöffnung für das Auf- und Absetzen des Helms gewährleistet ist. Aus der Fig. 2 ist etwa ersichtlich, dass die beiden Kinnbügelabschnitte 1a,1b jeweils in ihrem unteren Bereich eine seitlich in Richtung des Helminneren abstehende Kinnschutzfläche 6 aufweisen. Dadurch wird beim Schließen der Kinnbügelabschnitte 1a, 1b die Helmöffnung zusätzlich verringert, da sich die Kinnschutzflächen 6 aufeinander zu bewegen, und in der Schließposition der Kinnbügelabschnitte 1a, 1b schließlich bündig aneinander liegen. Dadurch wird nicht nur der Sitz des Helms verbessert, sondern auch bessere aerodynamische und aeroakustische Eigenschaften des Helms, sowie besserer Schutz gegen Wind, Schmutz und Kälte erreicht.The Fig. 2 shows a perspective side view of the embodiment of Fig. 1 in an open position of the chin bar sections 1a, 1b. As already mentioned, it is possible due to the measures according to the invention, the chin strap sections 1a, 1b structurally designed so that after putting on the helmet, the helmet opening is additionally reduced, thereby significantly improving the fit of the helmet, especially in the chin area, as by the pivoting of the chin guard sections a sufficiently large helmet opening for the raising and lowering of the helmet is guaranteed. From the Fig. 2 For example, it can be seen that the two chin guard sections 1a, 1b each have a chin protection surface 6 projecting laterally in the direction of the inside of the helmet in their lower region. As a result, when closing the chin guard sections 1a, 1b, the helmet opening is additionally reduced, since the chin guard surfaces 6 move towards one another, and in the closed position of the chin guard sections 1a, 1b finally lie flush against one another. This not only improves the fit of the helmet, but also achieves better aerodynamic and aeroacoustic properties of the helmet, as well as better protection against wind, dirt and cold.

Die Kinnbügelabschnitte 1a,1b werden im folgenden in einen Befestigungsbereich 7, der sich am der Helmschale 3 zugewandten Ende befindet, und in einen Schließbereich 13, der sich am der Helmschale 3 abgewandten Ende befindet, unterteilt. Der Schließbereich 13 weist jeweils eine Schließfläche 8 auf, wobei die beiden Schließflächen 8 in einer Öffnungsposition der beiden Kinnbügelabschnitte 1a,1b voneinander beabstandet sind, und in einer durch Verschwenken der beiden Kinnbügelabschnitte 1a,1b erreichbaren Schließposition aneinander anliegen. Schließfläche 8 kann auch noch mit einer Gummiflächendichtung (in den Fig. 1 bis 9 nicht dargestellt) zum Schutz gegen Eindringen von Wind und Nässe versehen werden.The chin strap sections 1a, 1b are subdivided below into a fastening region 7, which is located at the end facing the helmet shell 3, and into a closing region 13, which is located at the end facing away from the helmet shell 3. The closing region 13 in each case has a closing surface 8, wherein the two closing surfaces 8 are spaced apart from one another in an opening position of the two chin strap sections 1a, 1b and bear against one another in a closing position which can be achieved by pivoting the two chin strap sections 1a, 1b. Locking surface 8 can also still with a rubber surface seal (in the Fig. 1 to 9 not shown) to protect against the ingress of wind and moisture.

Die beiden Kinnbügelabschnitte 1a,1b sind in ihren jeweils oberen Abschnitten der Schließbereiche 13 außerdem über eine Gelenkverbindung 10 miteinander verbunden. Dadurch erfolgt stets ein synchrones Schließen der beiden Kinnbügelabschnitte 1a,1b, auch wenn mit den Händen auf die beiden Kinnbügelabschnitte 1a,1b unterschiedlicher Schließdruck ausgeübt wird. Wie bereits erwähnt wurde, kann durch diese Maßnahme das Schließen der Kinnbügelabschnitte 1a,1b auch einhändig erfolgen, da durch die Gelenkverbindung 10 eine Bewegung etwa des ersten Kinnbügelabschnitts 1a auf den zweiten Kinnbügelabschnitt 1b übertragen wird. Im Bereich der Schließflächen 8 kann auch ein Schließmechanismus 11,14 angeordnet sein, der die beiden Kinnbügelabschnitte 1a, 1b in ihrer Schließposition aneinander räumlich fixiert. In der Fig. 2 ist eine mögliche Ausführungsform eines solchen Schließmechanismus 11,14 mithilfe eines Hebels 14 angedeutet, der mit einem Stift 11 zusammenwirkt. Ein Anheben des Hebels 14 gibt dabei den Stift 11 frei, und die beiden Kinnbügelabschnitte 1a, 1b schwenken aufgrund der Vorspannung des Plattenelements 2 in ihre Öffnungsposition. Ein solcher Hebel 14 kann dabei auch einhändig bedient werden, was besonders vorteilhaft ist, und worauf bei der Auswahl des Schließmechanismus 11,14 auch Rücksicht genommen werden sollte.The two chin guard sections 1a, 1b are also connected to each other in their respective upper sections of the closing regions 13 via a hinge connection 10. As a result, there is always a synchronous closing of the two chin guard sections 1a, 1b, even if different closing pressure is exerted with the hands on the two chin bar sections 1a, 1b. As already mentioned, the closing of the chin guard sections 1a, 1b can also be done with one hand as a result of this measure, since a movement of approximately the first chin strap section 1a to the second chin strap section 1b is transmitted by the hinge connection 10. In the area of the closing surfaces 8 may also be arranged a closing mechanism 11,14, which is the two Chinrest sections 1a, 1b spatially fixed in their closed position to each other. In the Fig. 2 is a possible embodiment of such a closing mechanism 11,14 indicated by means of a lever 14 which cooperates with a pin 11. Lifting the lever 14 releases the pin 11, and the two chin strap sections 1a, 1b pivot into their open position due to the bias of the plate element 2. Such a lever 14 can also be operated with one hand, which is particularly advantageous, and what should be taken into account in the selection of the locking mechanism 11,14.

Die Gelenkverbindung 10 sollte deshalb in den jeweils oberen Abschnitten der Schließbereiche 13 angeordnet sein, da vorzugsweise jeder der beiden Kinnbügelabschnitte 1a,1b beim Öffnen nach unten und außen verschwenken soll, sodass sich die beiden Kinnbügelabschnitte 1a,1b beim Öffnen voneinander entfernen.The articulated connection 10 should therefore be arranged in the respective upper sections of the closing areas 13, since preferably each of the two chin bar sections 1a, 1b should pivot downwardly and outwardly during opening, so that the two chin bar sections 1a, 1b move away from one another during opening.

Aus der Fig. 2 ist des Weiteren ersichtlich, dass eine der Schließflächen 8 eine Nut 9 aufweist, und die andere Schließfläche 8 eine der Nut 9 zugeordnete Feder 15 (siehe etwa Fig. 4), wobei in der Schließposition Nut 9 und Feder 15 ineinander greifen. Dadurch können Scherkräfte der beiden Kinnbügelabschnitte 1a,1b im Falle eines Aufpralls besser aufgenommen und die Belastung der Gelenkverbindung 10 und des Schließmechanismus 11,14 verringert werden. So kann auch das ordnungsgemäße Funktionieren des Schließmechanismus 11,14 im Fall eines Unfalls und der dadurch verursachten Belastungen auf die Kinnbügelabschnitte 1a,1b sichergestellt werden.From the Fig. 2 It can also be seen that one of the closing surfaces 8 has a groove 9, and the other closing surface 8 has a groove 15 associated with the groove 9 (see, for example, FIG Fig. 4 ), wherein in the closed position groove 9 and spring 15 engage with each other. As a result, shearing forces of the two chin strap sections 1a, 1b can be better absorbed in the event of an impact and the load on the articulated connection 10 and the closing mechanism 11, 14 can be reduced. Thus, the proper functioning of the locking mechanism 11,14 in the event of an accident and the resulting stress on the chin guard sections 1a, 1b can be ensured.

In den frontalen Abschnitten der Kinnbügelabschnitte 1a,1b sind hierbei auch Lüftungsschlitze 23 ersichtlich, die eine ausreichende Ventilation des Helminneren sicherstellen und ein Beschlagen des Visiers 4 verhindern. Fig. 4 zeigt eine perspektivische Frontalansicht eines erfindungsgemäßen Schutzhelms der Ausführungsform von Fig. 1 in einer offenen Position der Kinnbügelabschnitte 1a, 1b, wobei auch die Feder 15 ersichtlich ist, die mit der Nut 9 (siehe Fig. 2) zusammenwirkt. Fig. 3 shows a perspective frontal view of a protective helmet according to the invention of the embodiment of Fig. 1 in the closed position of the chin bar sections 1a, 1b. In the frontal sections of the chin guard sections 1a, 1b, ventilation slots 23 can also be seen here, which ensure sufficient ventilation of the helmet interior and prevent fogging of the visor 4. Fig. 4 shows a perspective Frontal view of a protective helmet according to the invention of the embodiment of Fig. 1 in an open position of the chin guard portions 1a, 1b, wherein also the spring 15 can be seen, which with the groove 9 (see Fig. 2 ) cooperates.

Die Fig. 5 und 6 zeigen jeweils eine Schnittansicht der Darstellung gemäß Fig. 4, wobei sich bei der Fig. 5 die Kinnbügelabschnitte 1a,1b in einer offenen Position befinden, und bei der Fig. 6 in der geschlossenen Position. Die Fig. 5 und 6 zeigen außerdem auch die innere Beschichtung der Helmschale 3. Die Helmschale 3 selber stellt hierbei die äußerste Schutzhülle dar und verteilt die Kräfte beim Aufprall. Zur Herstellung der Helmschale 3 empfehlen sich duroplastische Kunststoffe, in Kunststoff eingebettete Glasfasermaterialien (GFK), oder thermoplastische Kunststoffe, etwa Polycarbonat (PC), Polyamid (PA) oder Acryl-Butadien-Styrol (ABS). Die Polsterung 12 kann sich aus einer Schutzpolsterung 12a, die im Inneren des Helms die bei einem Aufprall freigesetzte Energie abfängt und etwa aus Polystyrol (Styropor) besteht, und einer Komfortpolsterung 12b, die den Helm fest und bequem auf dem Kopf des Trägers fixiert und etwa aus Schaumstoff besteht, zusammensetzen. Auch die Kinnbügelabschnitte 1a,1b sowie deren Kinnschutzflächen 6 sind auf den dem Helminneren zugewandten Flächen mit einer Schutzpolsterung 12a und einer Komfortpolsterung 12b versehen. Dabei ist es vorteilhaft, wenn in der Öffnungsposition der Kinnbügelabschnitte 1a,1b deren Polsterung 12 die Polsterung 12 der Helmschale 3 stufenlos fortsetzt, um das Auf- und Absetzen des Helms zu erleichtern (siehe Fig. 5). In der Schließposition der Kinnbügelabschnitte 1a,1b liegt aber die Polsterung 12 der Kinnbügelabschnitte 1a,1b unter den Ohren des Trägers dicht an, bietet aber im Bereich der Ohren selbst genug Freiraum für angenehmen Tragekomfort und uneingeschränktes Hörempfinden. Auch das Tragen einer Brille ist dabei leicht und angenehm möglich. (Fig. 6). Die Polsterung 12 der Kinnbügelabschnitte 1a,1b sowie deren Kinnschutzflächen 6 ist außerdem vorzugsweise abnehmbar. Durch die Abnehmbarkeit können etwa Polsterungen 12 mit unterschiedlicher Dicke eingesetzt werden, sodass der Helm besser auf unterschiedliche Kopfgrößen abgestimmt werden kann.The Fig. 5 and 6 each show a sectional view of the illustration according to Fig. 4 , where at the Fig. 5 the chin guard portions 1a, 1b are in an open position, and in the Fig. 6 in the closed position. The Fig. 5 and 6 also show the inner coating of the helmet shell 3. The helmet shell 3 itself here represents the outermost protective cover and distributes the forces during impact. For the production of the helmet shell 3 recommend thermosetting plastics, embedded in plastic fiberglass (GRP), or thermoplastics, such as polycarbonate (PC), polyamide (PA) or acrylic-butadiene-styrene (ABS). The padding 12 may consist of a protective padding 12a, which intercepts the energy released in the interior of the helmet and consists approximately of polystyrene (polystyrene), and a comfort padding 12b, which fixes the helmet firmly and comfortably on the head of the wearer and about made of foam, put together. Also, the chin guard sections 1a, 1b and their chin protection surfaces 6 are provided on the surfaces facing the inside of the helmet with a protective padding 12a and a comfort padding 12b. It is advantageous if in the opening position of the chin guard sections 1a, 1b whose padding 12, the padding 12 of the helmet shell 3 continues continuously to facilitate the raising and lowering of the helmet (see Fig. 5 ). In the closed position of the chin guard sections 1a, 1b, however, the upholstery 12 of the chin bar sections 1a, 1b lies tightly under the ears of the wearer, but in the region of the ears provides enough free space for pleasant wearing comfort and unrestricted hearing. Wearing glasses is easy and pleasant. ( Fig. 6 ). The padding 12 of the chin guard sections 1a, 1b and their chin protection surfaces 6 is also preferably removable. The removability padding 12 can be used with different thicknesses so that the helmet can be better matched to different head sizes.

Der Sitz des Helmes wird dadurch verbessert. Außerdem kann die abnehmbare Polsterung 12 auch leichter gereinigt werden. Vorzugsweise verfügt die Helmschale 3 auch über einen Nackenschutz mit entsprechender Polsterung (in den Fig. 1 bis 9 nicht dargestellt).The seat of the helmet is thereby improved. In addition, the removable padding 12 can also be cleaned more easily. Preferably, the helmet shell 3 also has a neck guard with appropriate padding (in the Fig. 1 to 9 not shown).

In den Fig. 5 und 6 ist außerdem ersichtlich, dass der Befestigungsbereich 7 der beiden Kinnbügelabschnitte 1a, 1b jeweils mit einer der Helmschale 3 zugewandten Seitenfläche 16 abschließt, die in der Schließposition der Kinnbügelabschnitte 1a, 1b an einer Stützfläche 17 der Helmschale 3 anliegt (Fig. 6), und in der Öffnungsposition der Kinnbügelabschnitte 1a,1b von der Stützfläche 17 beabstandet ist (Fig. 5). Durch das Abstützen der Kinnbügelabschnitte 1a,1b an der Helmschale 3 in der Schließposition wird besserer Schutz bei Kräften, die von unten auf die Kinnbügelabschnitte 1a,1b wirken, gewährleistet. Insbesondere kann die Seitenfläche 16 des Befestigungsbereiches 7 der Kinnbügelabschnitte 1a,1b und die Stützfläche 17 der Helmschale 3 jeweils stufenförmig ausgebildet sein, sodass sich in der Seitenfläche 16 ein Falz 21 ausbildet, und in der Stützfläche 17 eine Stützleiste 22. In der Schließposition der Kinnbügelabschnitte 1a,1b greifen die stufenförmigen Abschnitte ineinander, indem die Stützleiste 22 im Falz 21 zu liegen kommt (Fig. 6). Dadurch können wiederum Scherkräfte zwischen Kinnbügelabschnitte 1a,1b und Helmschale 3 besser aufgenommen werden (Fig. 6).In the Fig. 5 and 6 It can also be seen that the fastening region 7 of the two chin strap sections 1a, 1b terminates in each case with a side face 16 facing the helmet shell 3, which abuts against a support surface 17 of the helmet shell 3 in the closed position of the chin strap sections 1a, 1b. Fig. 6 ), and in the opening position of the chin strap sections 1a, 1b is spaced from the support surface 17 ( Fig. 5 ). By supporting the chin guard sections 1a, 1b on the helmet shell 3 in the closed position, better protection is ensured for forces acting on the chin strap sections 1a, 1b from below. In particular, the side surface 16 of the attachment region 7 of the chin guard sections 1a, 1b and the support surface 17 of the helmet shell 3 can each be step-shaped, so that a fold 21 forms in the side surface 16, and a support strip 22 in the support surface 17. In the closed position of the chin guard sections 1a, 1b engage the step-shaped sections in one another, in that the support strip 22 comes to lie in the fold 21 (FIG. Fig. 6 ). As a result, shear forces between chin strap sections 1a, 1b and helmet shell 3 can in turn be better absorbed ( Fig. 6 ).

Die Fig. 7 zeigt eine perspektivische Ansicht einer Ausführungsform der Helmschale 3 eines erfindungsgemäßen. Schutzhelms, wobei die Polsterung 12 weggelassen wurde. Insbesondere ist die stufenförmige Ausführung der Stützfläche 17 unter Ausbildung der Stützleiste 22 erkennbar. Im Vergleich mit der Fig. 8, die eine perspektivische Ansicht einer Ausführungsform der Kinnbügelabschnitte 1a, 1b zeigt, ist ersichtlich, wie die Stützleiste 22 auf den Falz 21 der Seitenfläche 16 abgestimmt ist, sodass in der geschlossenen Position der Kinnbügelabschnitte 1a,1b die Stützleiste 22 vom Falz 21 aufgenommen wird. In dieser Position liegen die Seitenfläche 16 und die Stützfläche 17 aufeinander. Die Fig. 7 zeigt ferner, dass im Interesse einer besseren Aerodynamik die Plattenelemente 2 in einem abgestuften Bereich 18 der Helmschale 3 und der Kinnbügelabschnitte 1a,1b versenkt sein können, sodass sich eine stufenfreie Außenfläche der Helmschale 3 ergibt.The Fig. 7 shows a perspective view of an embodiment of the helmet shell 3 of an inventive. Protective helmets, wherein the padding 12 has been omitted. In particular, the step-shaped design of the support surface 17 can be seen by forming the support strip 22. In comparison with the Fig. 8 showing a perspective view of an embodiment of the chin bar sections 1a, 1b, it can be seen how the support strip 22 is matched to the fold 21 of the side surface 16, so that in the closed position of the chin bar sections 1a, 1b the support strip 22 is received by the fold 21. In this position are the Side surface 16 and the support surface 17 to each other. The Fig. 7 shows further that in the interests of better aerodynamics, the plate elements 2 can be recessed in a stepped portion 18 of the helmet shell 3 and the chin guard sections 1a, 1b, so that a stepless outer surface of the helmet shell 3 results.

Der Fig. 8 kann des Weiteren entnommen werden, dass die Seitenfläche 16 des Befestigungsbereiches 7 entlang ihrer Längserstreckung über eine Abschlussfläche 20 stumpf in die Kinnschutzfläche 6 übergeht. Der Fig. 7 kann wiederum entnommen werden, dass die Helmschale 3 eine Halteschulter 19 aufweist. Insbesondere in der geschlossenen Position der Kinnbügelabschnitte 1a, 1b stützt sich die Abschlussfläche 20 auf der Halteschulter 19 der Helmschale 3 ab. Dadurch werden Kräfte, die frontal auf die Kinnbügelabschnitte 1a,1b wirken, vom Helm besser aufgenommen. In der Fig. 8 ist ferner deutlich ersichtlich, wie die Kinnbügelabschnitte 1a,1b sowie deren Kinnschutzflächen 6 auf den dem Helminneren zugewandten Flächen mit einer Polsterung 12 versehen sind. Die Polsterung 12 der Kinnschutzflächen 6 kann zur Anpassung an unterschiedliche Kopfgrößen in verschiedenen Stärken ausgeführt werden und ist vorzugsweise abnehmbar. Des weiteren werden in der Regel auch an den inneren Seitenflächen der Kinnbügelabschnitte 1a,1b Polsterungen 12 vorgesehen sein, die aber in der Fig. 8 nicht eingezeichnet ist.Of the Fig. 8 Furthermore, it can be seen that the side surface 16 of the fastening region 7 blends into the chin protection surface 6 along its longitudinal extent via a closure surface 20. Of the Fig. 7 can in turn be deduced that the helmet shell 3 has a retaining shoulder 19. In particular, in the closed position of the chin guard sections 1a, 1b, the end surface 20 is supported on the retaining shoulder 19 of the helmet shell 3. As a result, forces acting frontally on the chin guard sections 1a, 1b are better absorbed by the helmet. In the Fig. 8 It is also clear how the chin guard sections 1a, 1b and their chin protection surfaces 6 are provided with a padding 12 on the surfaces facing the inside of the helmet. The padding 12 of the chin protection surfaces 6 can be designed to adapt to different head sizes in different strengths and is preferably removable. In addition, as a rule, padding 12 may also be provided on the inner lateral surfaces of the chin guard sections 1a, 1b, but these can be provided in the Fig. 8 is not shown.

Die Fig. 9 zeigt einen Detailausschnitt einer perspektivischen Ansicht der Ausführungsform von Fig. 1 eines erfindungsgemäßen Schutzhelms von unten gesehen. Dabei ist insbesondere eine mögliche Ausführungsvariante der Schließflächen 8 sowie des Schließmechanismus 11,14 ersichtlich. Wie bereits erwähnt wurde, weist eine der Schließflächen 8 eine Nut 9 auf, und die andere Schließfläche 8 eine der Nut 9 zugeordnete Feder 15 (siehe auch Fig. 2 und Fig. 4), wobei in der Schließposition Nut 9 und Feder 15 ineinander greifen. Des Weiteren ist deutlich die Gelenkverbindung 10 ersichtlich. Der Schließmechanismus 11,14 besteht in der gezeigten Ausführungsform aus einem Hebel 14, der mit einem Stift 11 zusammenwirkt. Ein Anheben des Hebels 14 gibt dabei den Stift 11 frei, und die beiden Kinnbügelabschnitte 1a,1b schwenken aufgrund der Vorspannung des Plattenelements 2 in ihre Öffnungsposition. Es sind aber auch andere Ausführungsformen des Schließmechanismus 11,14 denkbar, sie sollen jedenfalls robust und.einfach bedienbar sein.The Fig. 9 shows a detail of a perspective view of the embodiment of Fig. 1 a protective helmet according to the invention seen from below. In this case, in particular a possible embodiment of the closing surfaces 8 and the locking mechanism 11,14 can be seen. As already mentioned, one of the closing surfaces 8 has a groove 9, and the other closing surface 8 has a tongue 15 associated with the groove 9 (see also FIGS Fig. 2 and Fig. 4 ), wherein in the closed position groove 9 and spring 15 engage with each other. Furthermore, the hinge connection 10 can be clearly seen. The locking mechanism 11,14 consists in the embodiment shown of a lever 14 which cooperates with a pin 11. A lifting of the lever 14 gives while the pin 11 free, and the two chin strap sections 1a, 1b pivot due to the bias of the plate member 2 in its open position. But there are also other embodiments of the locking mechanism 11,14 conceivable, they should certainly be robust and.easy to use.
