Description

Beschreibungdescription
Schutzhelm, insbesondere militärischer SchutzhelmSafety helmet, in particular military safety helmet
Die Erfindung betrifft einen Schutzhelm, insbesondere militäri¬ schen Schutzhelm, mit einer stabilen Helmkalotte und einem aus mehreren miteinander verbundenen Bändern gebildeten Tragkorb, der an seine Bänder angeformte, zur Helmkalotte zeigende, pla- stisch verformbare Noppen aufweist und mit Befestigungsteilen so an mehreren Punkten mit der Helmkalotte verbunden ist, daß der Tragkorb über die Noppen mit einer Vorspannung an der In¬ nenseite der Helmkalotte anliegt.The invention relates to a safety helmet, in particular a military safety helmet, with a stable helmet cap and a carrying basket formed from a plurality of bands connected to one another, which has molded plastic knobs on its bands, pointing towards the helmet cap and thus with fastening parts at several points is connected to the helmet cap that the carrying basket rests with a prestress on the inside of the helmet cap via the knobs.
Ein derartiger Schutzhelm, wie er als militärischer Schutzhelm durch EP 0 423 379 Bl bekannt ist, verbindet die Funktion ei¬ ner guten Stoßdämpfung durch die plastisch verformbaren Noppen des Tragkorbes der Innenausstattung mit einer guten Durchlüft- barkeit des Helms. Die auch beim Aufprall von Geschossen auf die für militärische Zwecke beschußfeste Helmkalotte auftre¬ tenden Schläge werden dadurch wirksam bedämpft, daß die Noppen fest an der Innenseite der Helmkalotte anliegen und somit un¬ mittelbar beim Aufprall des Geschosses plastisch verformt wer¬ den. Die hierfür erforderliche Vorspannung des Tragekorbs ge- genüber der Helmkalotte wird durch eine entsprechende Befesti¬ gung des Tragkorbes an der Helmkalotte sichergestellt. Der Tragkorb wird üblicherweise fest mit der Helmkalotte ver¬ schraubt, wodurch die nötige Vorspannung gewährleistet werden kann.A protective helmet of this type, as is known as a military protective helmet from EP 0 423 379 B1, combines the function of good shock absorption through the plastically deformable knobs of the carrying basket of the interior with good ventilation of the helmet. The impacts that occur even when projectiles hit the helmet shell, which is bulletproof for military purposes, are effectively dampened by the knobs resting firmly on the inside of the helmet shell and thus being plastically deformed immediately upon impact of the projectile. The necessary pre-tensioning of the carrying basket with respect to the helmet cap is ensured by a corresponding fastening of the carrying basket to the helmet cap. The carrier cage is usually screwed tightly to the helmet cap, whereby the necessary pretension can be ensured.
Durch andere Typen von Schutzhelmen, beispielsweise Motorrad¬ helme, ist es bekannt, die Innenausstattung durch Druckknöpfe an der Helmkalotte zu befestigen und so insbesondere für Reini- gungszwecke herausnehmbar auszubilden. Aufgrund der Vorspan¬ nung, mit der der Tragkorb des gattungsgemäßen Schutzhelms zur Erzielung einer guten Stoßdämpfung an der Helmkalotte anliegen muß, ist eine Druckknopfbefestigung zur Gewährleistung der Herausnehmbarkeit des Tragkorbes nicht mit der erforderlichen Befestigungssicherheit realisierbar.It is known from other types of protective helmets, for example motorcycle helmets, to fasten the interior to the helmet cap by means of push buttons, and thus in particular for cleaning training purposes to be removable. Because of the pretension with which the carrying basket of the generic protective helmet has to rest against the helmet cap in order to achieve good shock absorption, a push-button fastening to ensure that the carrying basket can be removed cannot be realized with the required fastening security.
Zur Reinigung des Tragkorbes ist es daher bei den bekannten Schutzhelmen der gattungsgemäßen Art erforderlich, die übli- cherweise an drei Punkten erfolgte Verschraubung der Innenaus¬ stattung mit der Helmkalotte zu lösen, so daß ein gewisser Montage-aufwand benötigt wird.To clean the carrying cage, it is therefore necessary in the known protective helmets of the generic type to loosen the screwing of the interior fitting which is usually carried out at three points, so that a certain amount of assembly work is required.
Ausgehend von der Problemstellung, den Montageaufwand für die Entfernung der mit dem Tragkorb gebildeten Innenausstattung zu reduzieren ist erfindungsgemäß ein Schutzhelm der eingangs er¬ wähnten Art dadurch gekennzeichnet, daß die Verbindung von Be¬ festigungsteilen und Helmkalotte durch einen Bolzen und eine den Bolzen übergreifende Gabelanordnung gebildet ist, deren offene Seite so ausgerichtet ist, daß die Einführung des Bol¬ zens aus einer erhöhten Vorspannung des Tragkorbes gegen die Helmkalotte unter Reduzierung der Vorspannung erfolgt und daß der Bolzen durch Anliegen an der geschlossenen Seite der Ga¬ belanordnung die für den Gebrauch gewünschte Vorspannung si- chert.Starting from the problem of reducing the assembly effort for the removal of the interior formed with the carrying basket, a protective helmet of the type mentioned at the outset is characterized in that the connection of fastening parts and helmet cap is formed by a bolt and a fork arrangement which overlaps the bolt is, the open side of which is oriented such that the bolt is introduced from an increased pretension of the carrier cage against the helmet cap while reducing the pretension and that the bolt is in contact with the closed side of the fork arrangement for the pretension desired for use secures.
Erfindungsgemäß kann der Tragkorb ohne Montageaufwand von der Helmkalotte entfernt werden, wenn die Verbindung durch eine Bolzen-Gabel-Anordnung gebildet ist und die Montage so er- folgt, daß der Tragkorb in einen Zustand einer erhöhten Vor¬ spannung gepreßt wird und sich teilweise entspannend an der Bolzen-Gabel-Anordnung abstützt, so daß die für den Gebrauch verbleibende Vorspannung bereit szur Sicherung der Verbindung beiträgt, weil ein zu-fälliges Lösen der Verbindung wegen der dafür erforderlichen Erhöhung der Vorspannung in der Praxis ausgeschlossen ist. Die Sicherung der Bolzen-Gabel-Verbindung kann noch dadurch verbessert werden, daß die Gabel-Anordnung eine die offene Seite bildende elastisch verformbare Verengung als Einführweg für den Bolzen und an der geschlossenen Seite eine der Außen- abmessung des Bolzens entsprechende Aufnahmekammer aufweist, in die der Bolzen schnappend einführbar ist.According to the invention, the carrying cage can be removed from the helmet cap without assembly effort if the connection is formed by a pin and fork arrangement and the assembly is carried out in such a way that the carrying cage is pressed into a state of increased pretension and partially relaxes the bolt-fork arrangement supports so that the remaining bias ready for use contributes to securing the connection, because accidental loosening of the connection is impossible in practice because of the required increase in the bias. The securing of the bolt-fork connection can be further improved in that the fork arrangement has an elastically deformable constriction forming the open side as an insertion path for the bolt and on the closed side a receiving chamber corresponding to the outer dimension of the bolt, into which the bolt can be snapped in.
Mit der Bolzen-Gabel-Verbindung kann zusätzlich eine seitliche Sicherung herbeigeführt werden, wenn der Bolzen einen Bolzen- köpf aufweist, dessen Durchmesser größer als der der Aufnahme- kammer ist. Dabei kann der Bolzenkopf auf der Rückseite der Aufnahmekammer frei anliegen oder zur Erhöhung der Stabilität der Verbindung in einer Führungsnut geführt sein, die für den Bolzenkopf im Querschnitt T-förmig ausgebildet ist.The bolt-fork connection can additionally be used to secure the side if the bolt has a bolt head whose diameter is larger than that of the receiving chamber. The bolt head can rest freely on the back of the receiving chamber or be guided in a guide groove which is designed to be T-shaped in cross section for the bolt head in order to increase the stability of the connection.
Im allgemeinen wird es zweckmäßig sein, daß der Bolzen am Helm und die Gabel-Anordnung am Befestigungsstreifen angebracht sind. Der Bolzen läßt sich als Schraubbolzen in einfacher Wei¬ se am Helm befestigen, wobei durch Maßnahmen, wie sie in EP 0 662 286 AI offenbart sind, auch eine unverminderte Beschußfe- stigkeit im Bereich des für die Verschraubung erforderlichen Durchbruches der Helmkalotte erhalten bleiben kann.In general, it will be appropriate for the bolt to be attached to the helmet and the fork assembly to the mounting strip. The bolt can be attached to the helmet in a simple manner as a screw bolt, measures, as disclosed in EP 0 662 286 A1, also being able to maintain an undiminished resistance to fire in the area of the opening of the helmet cap required for the screw connection.
In einer bevorzugten Ausführungsform befinden sich die Befesti- gungspunkte im unteren Bereich des Tragkorbes, wobei dann die offene Seite der Gabel-Anordnung zur Öffnungsseite der Helmka¬ lotte zeigt, wenn die Gabel-Anordnung am Befestigungsteil ange¬ bracht ist.In a preferred embodiment, the fastening points are located in the lower region of the carrier basket, the open side of the fork arrangement then pointing towards the opening side of the helmet cap when the fork arrangement is attached to the fastening part.
Der erfindungsgemäß verwendete Bolzen kann zweckmäßigerweise gleichzeit zur Befestigung eines Kinnriemens ausgenutzt wer¬ den, wobei auch der Kinnriemen abnehmbar befestigt sein kann. Die Erfindung soll im folgenden anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert werden. Es zeigen:The bolt used according to the invention can expediently be used simultaneously for fastening a chin strap, wherein the chin strap can also be detachably attached. The invention will be explained in more detail below with reference to exemplary embodiments shown in the drawing. Show it:

Figur 8 eine Ansicht eines Befestigungsteils für einen Kinn¬ riemen.Figure 8 is a view of a fastening part for a chin strap.
Figur 1 läßt eine äußere Helmkalotte 1 erkennen, an deren In¬ nenseite ein Tragkorb 2 als Teil der Innenausstattung mit Hil¬ fe von drei Befestigungsmitteln 3 befestigt ist. Zwei der Be- festigungs- mittel 3 befinden sich im Schläfenbereich auf bei¬ den Seiten der Helmkalotte 1, das dritte Befestigungsmittel 3 mittig auf der Rückseite.FIG. 1 shows an outer helmet cap 1, on the inside of which a carrying basket 2 is fastened as part of the interior with the aid of three fastening means 3. Two of the fastening means 3 are located in the temple area on both sides of the helmet cap 1, the third fastening means 3 in the center on the back.
Der Tragkorb besteht aus einer zentralen Ringanordnung 4 , von der aus sich radial mehrere Bänder 5 erstrecken. Die radial er- streckten Bänder 5 sind durch Verbindungsbänder 6 miteinander verbunden. Im unteren Bereich münden die radialen Bänder 5 in ein Kopfband 7 ein, das im normalen Tragezustand etwa horizon¬ tal um den Kopf des Helmträgers umläuft.The carrier basket consists of a central ring arrangement 4, from which a plurality of bands 5 extend radially. The radially stretched bands 5 are connected to one another by connecting bands 6. In the lower area, the radial bands 5 open into a head band 7 which, in the normal wearing state, runs approximately horizontally around the head of the helmet wearer.
Die radialen Bänder 5, die Verbindungsbänder 6 und das Kopf- band 7 sind mit hohl ausgebildeten Noppen 8 versehen, über die der Tragkorb 2 an der Innenseite der Helmkalotte 1 anliegt. Die hierfür benötigte Vorspannung wird durch die geeignete Lage der Befestigungsmittel 3 erreicht und wird wirksam, weil der Tragkσrb 2, der vorzugsweise aus Kunststoff gebildet ist, eine eigene Formstabilität aufweist. Die Noppen 8 sind aus dem Material des Tragkorbes 2 gebildet und plastisch durch höhere Drücke verformbar, so daß Stoß- oder Schlagenergie durch die plastische Verformung von den Noppen 8 aufgenommen wird.The radial bands 5, the connecting bands 6 and the head band 7 are provided with hollow knobs 8, by means of which the carrying basket 2 rests on the inside of the helmet cap 1. The pretension required for this is achieved by the suitable position of the fastening means 3 and is effective because the support basket 2, which is preferably formed from plastic, has its own dimensional stability. The knobs 8 are formed from the material of the carrying basket 2 and can be plastically deformed by higher pressures, so that impact or impact energy is absorbed by the knobs 8 due to the plastic deformation.
Figur 1 läßt auch erkennen, daß einige der Noppen 8, beispiels¬ weise im Bereich von Ohrwölbungen der Helmkalotte 1 nicht an der Innenseite der Helmkalotte anliegen. Dies gilt jedoch für die meisten der Noppen 8, so daß der Tragkorb in seiner Ge¬ samtheit durch die von den Befestigungsmitteln 3 aufgebrachte Vorspannung an der Innenseite der Helmkalotte 1 unter Vorspan¬ nung anliegt.FIG. 1 also shows that some of the knobs 8, for example in the area of the ear curvature of the helmet cap 1, do not lie against the inside of the helmet cap. However, this applies to most of the knobs 8, so that the carrying cage, as a whole, bears against the inside of the helmet cap 1 under pre-tensioning due to the pre-tension applied by the fastening means 3.
Figur 2 verdeutlicht, daß der Tragkorb 2 Befestigungsteile 9 aufweist, die zusammen mit einem in die Helmkalotte 1 einge¬ schraubten Bolzen 10 das Befestigungsmittel 3 bilden. In dem dargestellten Ausführungsbeispiel ist das Befestigungsteil 9 in Form eines L-förmigen Winkels an den Tragkorb 2 angeformt und umgreift einen von der Helmkalotte 1 nach innen vorstehen¬ den Teil des Bolzens 10 teilweise. Eine seitliche Begrenzung für das Befestigungsteil 9 ergibt sich durch einen am freien Ende des Bolzens 10 angeordneten Bolzenkopf 11, der das Befe¬ stigungsteil 9 in Position hält.FIG. 2 illustrates that the carrying basket 2 has fastening parts 9 which, together with a bolt 10 screwed into the helmet cap 1, form the fastening means 3. In the exemplary embodiment shown, the fastening part 9 is formed in the form of an L-shaped angle on the support cage 2 and partially engages around a part of the bolt 10 which projects inwards from the helmet cap 1. A lateral limitation for the fastening part 9 results from a bolt head 11 which is arranged at the free end of the bolt 10 and which holds the fastening part 9 in position.
In Figur 2 ist ferner angedeutet, daß der Bolzen 10 ferner eine Befestigungseinrichtung 12 für einen Kinnriemen 13 trägt, der somit an den Bolzen 10 der beiden seitlichen Befestigungs- mittel 3 befestigt ist.In Figure 2 it is also indicated that the bolt 10 also carries a fastening device 12 for a chin strap 13, which thus on the bolt 10 of the two lateral fastening medium 3 is attached.
Figur 3 zeigt eine Ausführungsvariante der Anordnung gemäß Figur 2, bei der das Befestigungsteil 9' an den Tragkorb 2 durch einen Niet 14 angenietet ist und somit aus einem anderen Material als der Tragkorb 2 bestehen kann. Hierdurch kann, falls erforderlich, eine höhere Formstabilität der Befesti¬ gungsteile 9' erreicht werden.FIG. 3 shows an embodiment variant of the arrangement according to FIG. 2, in which the fastening part 9 'is riveted to the carrier basket 2 by a rivet 14 and can therefore be made of a different material than the carrier basket 2. In this way, if necessary, a higher dimensional stability of the fastening parts 9 'can be achieved.
Figur 4 zeigt einen Schnitt gemäß Figur 2 (Figur 4b) und eine Draufsicht des Befestigungsteils 9. Das Befestigungsteil ist L-förmig abgekröpft und bildet eine parallel zur Innenseite der Helmkalotte 1 liegende flächige Gabel-Anordnung 15 mit einer Aufnähmekammer 16 und einem Einführschlitz 17, der als zur Aufnahmekammer 16 konisch verjüngte Verengung ausgebildet ist. Der Durchmesser der Aufnahmekammer 16 entspricht dem Au¬ ßendurchmesser des von der Helmkalotte 1 vorstehenden Bolzens 10, der durch die Verengung 17 in Richtung des Pfeiles A in Figur 4 in die Aufnahmekammer 16 drückbar ist und dort in ei- ner Schnappverbindung gehalten wird.FIG. 4 shows a section according to FIG. 2 (FIG. 4b) and a top view of the fastening part 9. The fastening part is bent into an L-shape and forms a flat fork arrangement 15 lying parallel to the inside of the helmet cap 1 with a receiving chamber 16 and an insertion slot 17, which is designed as a conical taper to the receiving chamber. The diameter of the receiving chamber 16 corresponds to the outer diameter of the bolt 10 protruding from the helmet cap 1, which can be pressed into the receiving chamber 16 by the constriction 17 in the direction of arrow A in FIG. 4 and is held there in a snap connection.
Die Ausführung der Einführungsbewegung des Bolzens 10 in die Aufnahmekammer 16 der Gabel-Anordnung 15 setzt voraus, daß - wie den Figuren 2 und 3 zu entnehmen ist - der Tragkorb 2 stärker als in der Gebrauchsstellung gemäß Figur 2 oder 3 in Richtung Helmoberseite gedrückt wird, wobei sich der Tragkorb 2 beim Einführen durch die Verengung 17 in die Aufnahmekammer 16 teilweise wieder entspannt. Das der Verengung 17 gegenüber¬ liegende geschlossene Ende der Aufnahmekammer 16 bewirkt zu- sammen mit dem Bolzen 10, daß der Tragkorb 2 in der in Ge¬ brauchsstellung gewünschten Vorspannung gegenüber der Innen¬ seite der Helmkalotte 1 gehalten wird.The execution of the insertion movement of the bolt 10 into the receiving chamber 16 of the fork arrangement 15 presupposes that - as can be seen from FIGS. 2 and 3 - the carrying basket 2 is pressed more strongly towards the top of the helmet than in the use position according to FIG. 2 or 3, whereby the carrier basket 2 partially relaxes again when inserted through the constriction 17 into the receiving chamber 16. The closed end of the receiving chamber 16 opposite the constriction 17, together with the bolt 10, causes the carrying basket 2 to be held in the prestress desired in the use position with respect to the inside of the helmet cap 1.
Figur 5 verdeutlicht, daß der Bolzen 10 aus einer Flachkopf- schraube 18 und einer Hülse 19 zusammengesetzt ist. Die Befe¬ stigung des Bolzens 10 geschieht daher durch Verschraubung der Flachkopfschraube 18 mit der Hülse 19, die in dem dargestell¬ ten Ausführungsbeispiel auf der Innenseite der Helmkalotte 1 durch das in eine Nut 20 eingeschnappte Befestigungsteil 12 des Kinn-riemens 13 positioniert wird. Zwischen Befestigungs¬ teil 12 und Bolzenkopf 11, der durch den Boden der Hülse 19 gebildet ist, befindet sich der Raum für die Aufnahme der Ga- bel-Anordnung 15.FIG. 5 illustrates that the bolt 10 is composed of a flat-head screw 18 and a sleeve 19. The bolt 10 is therefore fastened by screwing the flat-head screw 18 to the sleeve 19, which in the exemplary embodiment shown is on the inside of the helmet cap 1 is positioned by the fastening part 12 of the chin strap 13 which is snapped into a groove 20. Between the fastening part 12 and the bolt head 11, which is formed by the bottom of the sleeve 19, there is the space for receiving the fork arrangement 15.
Die Figuren 6 und 7 zeigen zwei konkrete Ausführungsformen von Befestigungsstücken 9'' und 9'''. Das in Figur 6 dargestellte Befestigungsstück 9'' wird in dem Ausführungsbeispiel gemäß Fi- gur 1 als Befestigungsmittel 3 am hinteren Ende der Helmkalot¬ te 1 verwendet. Das Befestigungsteil 9'' weist von dem Tragkorb 2 ausgehend eine Höhe auf, die der Höhe benachbarter Noppen 8 entspricht (Fig. 6b), so daß die der Helmkalotte 1 zugewandte Oberfläche des Befestigungsteils 9'' mit der Ober- seite der Noppen 8 bezüglich der Innenseite der Helmkalotte 1 etwa fluchtet. Figur 6a läßt erkennen, daß das Befestigungs¬ teil 9'' die Aufnahmekammer 16 und einen die Verengung 17 bil¬ denden Schlitz aufweist, in die der Bolzen 10 nach Herstellung einer übergroßen Vorspannung einführbar ist, wobei sich die Vorspannung des Tragkorbs 2 teilweise wieder entspannt.Figures 6 and 7 show two specific embodiments of fasteners 9 '' and 9 '' '. The fastening piece 9 ″ shown in FIG. 6 is used in the exemplary embodiment according to FIG. 1 as fastening means 3 at the rear end of the helmet cap 1. Starting from the carrying basket 2, the fastening part 9 ″ has a height which corresponds to the height of adjacent knobs 8 (FIG. 6b), so that the surface of the fastening part 9 ″ facing the helmet cap 1 is in relation to the top of the knobs 8 the inside of the helmet 1 is approximately aligned. FIG. 6a shows that the fastening part 9 ″ has the receiving chamber 16 and a slit forming the constriction 17, into which the bolt 10 can be inserted after an excessive preload has been produced, the preload of the carrying basket 2 partially relaxing again .
Figur 6c verdeutlicht, daß in dem Befestigungsteil 9'' Aufnah- mekammer 16 und Schlitz 17 Teil einer im Querschnitt T-förmi- gen Nut 21 sind, wobei die T-förmige Erweiterung 22 der Nut 21 der Führung des Bolzenkopfs 11 dient.FIG. 6c illustrates that in the fastening part 9 ″ receiving chamber 16 and slot 17 are part of a groove 21 with a T-shaped cross section, the T-shaped widening 22 of the groove 21 serving to guide the bolt head 11.
Figur 7 zeigt eine weitere Ausführungsform eines Befestigungs¬ teils 9''', die sich bezüglich der Aufnahmekammer 16, des Schlitzes 17 und der T-förmigen Nut 21 nicht von dem Befesti- gungsteil 9'' unterscheidet. Wie Figur 7b zeigt, entspricht diese Ausführungsform der winkeligen Ausbildung des Befesti¬ gungsteils 9 gemäß Figur 2, wobei die Höhe des Befestigungs¬ teils 9 ' ' ' etwas niedriger ist als die Höhe einer benachbarten Noppe 8, weil zusätzlich zu dem Befestigungsteil 9''' auf den Bolzen 10 noch das Befestigungsstück 12 für den Kinnriemen aufgebracht wird. Die Höhendifferenz zwischen Befestigungsteil 9''' und Bolzen 8 wird daher durch die Stärke des Befesti¬ gungsteils 12 für den Kinn-riemen 13 etwas ausgefüllt. Ein Befestigungsteil 12 für einen Kinnriemen 13 ist in Figur 8 dargestellt. Dieses weist eine der Aufnahmekammer 16 entspre¬ chende Aufnahmekammer 23 für den Bolzen 10 auf. Die Aufnahme¬ kammer 23 ist über eine Verengung 24 mit einer Einführungsöff- nung 25 verbunden, deren Durchmesser größer als der Durchmes¬ ser des Bolzenkopfs 11 ist, so daß der Bolzenkopf 11 durch die Ein-führungsöffnung 25 hindurch gesteckt werden kann, worauf¬ hin der Bolzen über die Verengung 24 in die Aufnahmekammer 23 einschnappbar ist. Der Kinnriemen 13 ist somit über den Bolzen 10 rastend hängbar. Die Bewegungsrichtung des Befestigungs¬ teils 12 relativ zum Bolzen für die Montage des Kinnriemens 13 ist in Figur 8 durch den Pfeil B angedeutet.FIG. 7 shows a further embodiment of a fastening part 9 ″ ″, which does not differ from the fastening part 9 ″ with respect to the receiving chamber 16, the slot 17 and the T-shaped groove 21. As FIG. 7b shows, this embodiment corresponds to the angular configuration of the fastening part 9 according to FIG. 2, the height of the fastening part 9 '''being somewhat lower than the height of an adjacent knob 8, because in addition to the fastening part 9'''The fastening piece 12 for the chin strap is also applied to the bolt 10. The height difference between the fastening part 9 '''and the bolt 8 is therefore somewhat filled by the strength of the fastening part 12 for the chin strap 13. A fastening part 12 for a chin strap 13 is shown in FIG. 8. This has a receiving chamber 23 corresponding to the receiving chamber 16 for the bolt 10. The receiving chamber 23 is connected via a constriction 24 to an insertion opening 25, the diameter of which is larger than the diameter of the bolt head 11, so that the bolt head 11 can be inserted through the insertion opening 25, whereupon the bolt can be snapped into the receiving chamber 23 via the constriction 24. The chin strap 13 can thus be hung in a latching manner via the bolt 10. The direction of movement of the fastening part 12 relative to the bolt for the assembly of the chin strap 13 is indicated by the arrow B in FIG.
Aus den dargestellten Ausführungsbeispielen ist erkennbar, daß durch die Ausbildung der Befestigungseinrichtungen 3 mit einem Bolzen 10 und einer Gabel-Anordnung 15 die Vorspannung des Trag-korbes 2 gegenüber der Helmkalotte 1 für die Befestigung nicht nur nicht hinderlich ist, sondern für die Stabilität der Befestigung ausgenutzt wird, wobei zur Montage der Befesti- gungsvorrichtung 3 der Tragkorb 2 in eine übergroße Vorspan¬ nung gedrückt werden muß, aus der er sich teilweise entspan¬ nend in die Gabel-Anordnung 15 hineindrückt und dort unter Vorspannung an dem dem Schlitz 17 gegenüberliegenden geschlos¬ senen Ende der Aufnahmekammer 16 anliegt. From the illustrated embodiments it can be seen that the design of the fastening devices 3 with a bolt 10 and a fork arrangement 15 makes the pretensioning of the carrying basket 2 relative to the helmet cap 1 not only not a hindrance for the fastening, but for the stability of the fastening is used, whereby for mounting the fastening device 3, the carrying basket 2 must be pressed into an excessively large pretension, from which it presses partially in a relaxing manner into the fork arrangement 15 and is closed there under pretension on the opposite slot 17 ¬ its end of the receiving chamber 16 abuts.
