Definitions
- the invention relates to a protective helmet u. a. for work or sport, with a fork chin strap, which consists of two fork straps connected on both sides of the helmet, each in the area of the helmet rim, approximately in the center of the helmet on the one hand and around the temple area on the other, and a chin strap that connects both fork straps and to each fork strap by means of a length the fork belt movable fitting is connected, which has a plurality of mutually inclined slots, through which the fork belt connected in one piece on the fitting passes and in which the fork belt is jammed under tension exerted by the chin strap on the fitting.
- Protective helmets of this type are known from the documents US-A-4 044 400, US-A-2 846 683 and DE-GM-83 06 006 and offer the possibility of holding the protective helmet on the head without slipping even when there are changing forces, if the fork chin straps are correctly adjusted, i.e. the connection between the fork straps and the chin strap causing the fitting is shifted along each fork strap so that the force distribution between the chin strap and the fork strap parts on both sides of the fitting results in an even load on both fork strap parts.
- the invention has for its object to provide a protective helmet of the type mentioned in such a way that both fork straps can be easily and simply adjusted together and simultaneously with regard to their total length effective between the neck and temple-side helmet attachment points.
- the two fork belts are connected to one another and together with a central belt at the end of their neck-side belt parts facing away from the respective fitting, which is essentially in the apex plane of the helmet runs and is connected to the helmet in an adjustable length.
- the length of the fork straps between their temple-side helmet connection on the one hand and the common connection on the center belt remains unchanged, but their overall effective length, which is decisive for the correct setting of the fork chin straps, between the temple and neck-side helmet connections can be adjusted in a simple manner by adjusting the center belt and can be changed together or simultaneously for both fork belts.
- the length of the middle strap is just as easy to adjust as the fittings can be moved along the fork straps, for example even with a protective helmet on, which greatly simplifies, simplifies and accelerates the individual adjustment of the fork chin straps to the helmet wearer.
- a preferred embodiment of the invention is characterized in that the fork belts are integrally connected at the ends of the neck-side belt parts which are connected to one another and to the central belt.
- a particularly expedient embodiment in this respect is characterized in that the two neck-side belt parts on the central belt are placed one above the other in a fold running transversely to the central belt, including an angle, and are sewn to one another and to the central belt.
- the advantage of this arrangement is above all that both fork belts are only formed by a single continuous belt piece, the angle at which the two fork belts converge on the central belt, chosen as desired and can be easily adapted to the respective helmet type and training. At the same time, a reliable connection of both fork belts to the middle belt is obtained, which can withstand any load.
- the length-adjustable connection of the center belt to the helmet can be achieved in various ways.
- the center strap can have several consecutive holes in its longitudinal direction and, depending on the desired length, can optionally be buttoned onto one of these holes on the helmet.
- a better and therefore preferred embodiment within the scope of the invention, however, is characterized in that for the connection of the central belt to the helmet, three slots are provided which run parallel to one another and transversely to the apex plane and which are passed through one after the other by the central belt to form a loop which moves under tension automatically tighten the center belt in the slots.
- Such a connection enables the length of the center belt to be continuously adjusted and does not require any further fastening parts on the helmet for connecting the center belt.
- Both fork straps generally have the same length from the middle strap connection to the temple-side helmet connection and are not adjustable to the helmet with regard to this length in the temple area connected.
- this can easily be taken into account by the fact that the fork straps in the temple area are connected to the helmet with adjustable length, for which purpose in turn, the helmet has three slots for each fork belt which are transverse to one another and to the longitudinal direction of the belt and which the fork belt has successively passed through to form a loop which automatically tightens in the slots under tension on the fork belt.
- the fork straps are attached to the helmet with their end on the side of the temple in the same way, continuously adjustable in length, as the center strap.
- the protective helmet shown in the drawing is specially designed for cyclists and has a three-part helmet shell, consisting of two side parts 2 opposite each other on the apex level 1-1 of the helmet and a central part 3 arching the side parts 2 along the apex. Between the central part 3 and the side parts 2 each have free joints 4 which separate the middle part 3 and the side parts 2 from each other over the entire length of the middle part 3 and thereby enable the middle part 3 which is elastically bendable in the apex plane 1-1 in the sense of a change in its curvature in deform the apex.
- the side parts 2 and the middle part 3 are connected to one another by a band 5, which runs like a ring in a transverse plane approximately perpendicular to the apex plane 1-1, which goes through the two end regions of the middle part 3 and through the two side parts 2.
- the band 5 is adjustable with respect to its ring circumference and can be locked in the desired ring circumference.
- helmets are known for example from DE-GM 87 02 777 and therefore do not require any further description here.
- the protective helmet which can of course also be designed in a different way and can be used for other purposes, is equipped with fork chin straps, the two on both sides of the protective helmet, each in the area of the helmet rim approximately in the rear helmet center at 6 on the one hand and approximately in the temple area at 7 on the other connected fork straps 8, 8 ', of which in Fig. 1 only one, namely the front in oblique view, is shown in full.
- For fork chin strapping further includes a chin strap 9 which connects both fork straps 8, 8 'and is connected to each fork belt 8, 8' by means of a fitting 10 which can be displaced along the fork belt.
- This fitting 10 consists of a fitting plate with three slots 11 which are inclined with their longitudinal direction so that the fork belt 8, 8 'running through all three slots 11 of the fitting 10' with its two neck or temple-side belt parts for each fork chin strap or the respective type of protective helmet includes the most favorable angle 12, usually an essentially right angle.
- the chin strap 9 is hung with a loop 9 'in the middle slot of each fitting 10, but can also be riveted directly to the fitting or connected in some other way.
- the chin strap 9 can have a chin pad 12 and a plug lock 13, the two lock parts of which are shown open in the drawing, and which enables the chin strap 9 to be closed or opened in a simple manner.
- Protective helmets with fork chin straps of this type are known from DE-GM 83 06 006 and therefore do not require any further description here either.
- the fork belts 8, 8 'are connected to one another at the ends of the neck-side belt parts which are connected to one another and to the center belt 14, the two neck-side belt parts on the center belt 14 being folded over and including an angle 16 in a fold 15 running transversely to the center belt 14 are connected to each other and to the central belt 14 by seams 17.
- the angle 16 between the neck-side belt parts meeting on the central belt 14 can be optimally adapted to the respective requirements of the protective helmet, its type and size.
- both fork straps 8, 8 'each have the same length from the center belt connection to the temple-side helmet connection 7. In the temple area, they are connected to the helmet in an unadjustable manner with respect to this length, for which purpose they are held by holes 7 'or eyelets on suitable fastening pins which are provided on the inside of the helmet shell 3.
Abstract
Description
Die Erfindung betrifft einen Schutzhelm u. a. für Arbeit oder Sport, mit einer Gabelkinnberiemung, die auf zwei beidseits am Helm jeweils im Bereich des Helmrandes etwa in der hinteren Helmmitte einerseits und etwa im Schläfenbereich andererseits angeschlossenen Gabelriemen und einem Kinnriemen besteht, der beide Gabelriemen verbindet und dazu an jeden Gabelriemen mittels eines längs des Gabelriemens verschiebbaren Beschlags angeschlossen ist, der mehrere zueinander geneigte Schlitze aufweist, die von dem am Beschlag einstückig zusammenhängenden Gabelriemen durchlaufen sind und in denen sich der Gabelriemen unter vom Kinnriemen auf den Beschlag ausgeübtem Zug verklemmt.The invention relates to a protective helmet u. a. for work or sport, with a fork chin strap, which consists of two fork straps connected on both sides of the helmet, each in the area of the helmet rim, approximately in the center of the helmet on the one hand and around the temple area on the other, and a chin strap that connects both fork straps and to each fork strap by means of a length the fork belt movable fitting is connected, which has a plurality of mutually inclined slots, through which the fork belt connected in one piece on the fitting passes and in which the fork belt is jammed under tension exerted by the chin strap on the fitting.
Schutzhelme dieser Art sind aus den Dokumenten US-A-4 044 400, US-A-2 846 683 und DE-GM-83 06 006 bekannt und bieten die Möglichkeit, den Schutzhelm auch bei wechselnden Krafteinwirkungen rutschfrei auf dem Kopf zu halten, wenn die Gabelkinnberiemung richtig eingestellt ist, d.h. der die Verbindung zwischen den Gabelriemen und dem Kinnriemen bewirkende Beschlag längs jedes Gabelriemens so verschoben ist, daß die Kraftverteilung zwischen dem Kinnriemen und den Gabelriementeilen beidseits des Beschlags eine möglichst gleichmäßige Beanspruchung beider Gabelriementeile ergibt. Im unbelasteten Zustand lassen sich die Beschläge längs der an ihnen durchlaufenden Gabelriemen leicht verschieben, um die günstigste Stellung für die Beschläge zu finden, unter Belastung dagegen verklemmen sich die Beschläge an ihrem jeweiligen Gabelriemen, so daß die einmal erzielte optimale Einstellung auch tatsächlich beibehalten bleibt. - Bei der beschriebenen Einstellung der Beschläge an den Gabelriemen bleibt die Gesamtlänge jedes Gabelriemens zwischen seinen nacken- und schläfenseitigen Helmanschlußpunkten unverändert. Um auch diese Gesamtlänge noch individuell einstellen zu können, sind bei den bekannten Schutzhelmen beide Gabelriemen am schläfenseitigen Ende jeweils lösbar am Schutzhelm so angeschlossen, daß sie mehrere Befestigungen mit jeweils anderer Riemengesamtlänge ermöglichen, beispielsweise in Riemenlängsrichtung hintereinander mehrere Löcher aufweisen und wahlweise mit einem dieser Löcher am Schutzhelm angeknüpft werden können. Dies hat sich zwar bewährt, ist aber umständlich, weil beide Gabelriemen getrennt voneinander in ihrer Gesamtlänge eingestellt werden müssen.Protective helmets of this type are known from the documents US-A-4 044 400, US-A-2 846 683 and DE-GM-83 06 006 and offer the possibility of holding the protective helmet on the head without slipping even when there are changing forces, if the fork chin straps are correctly adjusted, i.e. the connection between the fork straps and the chin strap causing the fitting is shifted along each fork strap so that the force distribution between the chin strap and the fork strap parts on both sides of the fitting results in an even load on both fork strap parts. In the unloaded state, the Slightly move the fittings along the fork straps running through them in order to find the most favorable position for the fittings, but under load the fittings jam on their respective fork straps so that the optimum setting once achieved is actually retained. - With the described adjustment of the fittings on the fork belts, the total length of each fork belt between its neck and temple-side helmet attachment points remains unchanged. In order to be able to adjust this overall length individually, in the known protective helmets both fork straps are detachably connected to the protective helmet at the temple end so that they enable multiple fastenings with different overall strap lengths, for example several holes in a row in the longitudinal direction of the belt and optionally with one of these holes can be attached to the safety helmet. This has proven itself, but is cumbersome, because the length of both fork belts must be adjusted separately.
Der Erfindung liegt die Aufgabe zugrunde, einen Schutzhelm der eingangs genannten Art so auszubilden, daß beide Gabelriemen bezüglich ihrer zwischen den nacken- und schläfenseitigen Helmanschlußpunkten wirksamen Gesamtlänge leicht und einfach gemeinsam und gleichzeitig eingestellt werden können.The invention has for its object to provide a protective helmet of the type mentioned in such a way that both fork straps can be easily and simply adjusted together and simultaneously with regard to their total length effective between the neck and temple-side helmet attachment points.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die beiden Gabelriemen an dem vom jeweiligen Beschlag abgewandten Ende ihrer nackenseitigen Riementeile miteinander und gemeinsam mit einem Mittelriemen verbunden sind, der im wesentlichen in der Scheitelebene des Helms verläuft und längenverstellbar an den Helm angeschlossen ist.This object is achieved according to the invention in that the two fork belts are connected to one another and together with a central belt at the end of their neck-side belt parts facing away from the respective fitting, which is essentially in the apex plane of the helmet runs and is connected to the helmet in an adjustable length.
Bei dem erfindungsgemäßen Schutzhelm bleibt zwar die Länge der Gabelriemen zwischen ihrem schläfenseitigen Helmanschluß einerseits und dem gemeinsamen Anschluß am Mittelriemen unverändert, jedoch kann ihre für die richtige Einstellung der Gabelkinnberiemung insgesamt maßgebliche wirksame Länge zwischen den schläfen- und nackenbseitigen Helmanschlüssen durch Verstellen des Mittelriemens in einfacher Weise und gemeinsam bzw. gleichzeitig für beide Gabelriemen geändert werden. Die Länge des Mittelriemens ist ebenso leicht verstellbar wie die Beschläge längs der Gabelriemen verschiebbar sind, also beispielsweise auch bei aufgesetztem Schutzhelm, was die individuelle Anpassung der Gabelkinnberiemung an den Helmträger außerordentlich erleichtert, vereinfacht und beschleunigt.In the protective helmet according to the invention, the length of the fork straps between their temple-side helmet connection on the one hand and the common connection on the center belt remains unchanged, but their overall effective length, which is decisive for the correct setting of the fork chin straps, between the temple and neck-side helmet connections can be adjusted in a simple manner by adjusting the center belt and can be changed together or simultaneously for both fork belts. The length of the middle strap is just as easy to adjust as the fittings can be moved along the fork straps, for example even with a protective helmet on, which greatly simplifies, simplifies and accelerates the individual adjustment of the fork chin straps to the helmet wearer.
Eine bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß die Gabelriemen an den miteinander und mit dem Mittelriemen verbundenen Enden der nackenseitigen Riementeile einstückig zusammenhängen. Eine insoweit besonders zweckmäßige Ausführungsform ist dadurch gekennzeichnet, daß die beiden nackenseitigen Riementeile am Mittelriemen in einer quer zum Mittelriemen verlaufenden Falte unter Einschluß eines Winkels übereinander gelegt und miteinander und mit dem Mittelriemen vernäht sind. Der Vorteil dieser Anordnung besteht vor allem darin, daß beide Gabelriemen nur noch von einem einzigen durchlaufenden Riemenstück gebildet sind, wobei der Winkel, unter dem die beiden Gabelriemen am Mittelriemen zusammenlaufen, nach Wunsch gewählt und somit der jeweiligen Helmart und -ausbildung unschwer angepaßt werden kann. Gleichzeitig wird eine zuverlässige Verbindung beider Gabelriemen mit dem Mittelriemen erhalten, die jeder Belastung Stand hält.A preferred embodiment of the invention is characterized in that the fork belts are integrally connected at the ends of the neck-side belt parts which are connected to one another and to the central belt. A particularly expedient embodiment in this respect is characterized in that the two neck-side belt parts on the central belt are placed one above the other in a fold running transversely to the central belt, including an angle, and are sewn to one another and to the central belt. The advantage of this arrangement is above all that both fork belts are only formed by a single continuous belt piece, the angle at which the two fork belts converge on the central belt, chosen as desired and can be easily adapted to the respective helmet type and training. At the same time, a reliable connection of both fork belts to the middle belt is obtained, which can withstand any load.
Der längenverstellbare Anschluß des Mittelriemens am Helm kann auf verschiedene Weise verwirklicht werden. So kann der Mittelriemen in seiner Längsrichtung mehrere aufeinander folgende Löcher aufweisen und je nach gewünschter Länge wahlweise mit einem dieser Löcher am Helm angeknöpft werden. Eine bessere und daher im Rahmen der Erfindung bevorzugte Ausführungform aber ist dadurch gekennzeichnet, daß zum Anschluß des Mittelriemens am Helm drei zueinander parallel und quer zur Scheitelebene verlaufende Schlitze vorgesehen sind, die vom Mittelriemen nacheinander unter Bildung einer Schlaufe durchlaufen sind, die sich unter Zug auf den Mittelriemen selbsttätig in den Schlitzen festzieht. Ein solcher Anschluß ermöglicht die kontinuierliche Verstellung der Länge des Mittelsriemens und erfordert am Helm keine weiteren Befestigungsteile für den Anschluß des Mittelriemens. Insgesamt wird daher eine quer zur Helmschale, also in Richtung ihrer Dicke, nur sehr wenig auftragende Anschlußmöglichkeit für den Mittelriemen geschaffen. Selbstverständlich ist im übrigen die Länge der Schlitze jeweils nur gleich der Breite des Mittelriemens, so daß der Mittelriemen in den Schlitzen nicht quer zu seiner Längsrichtung verrutschen kann.The length-adjustable connection of the center belt to the helmet can be achieved in various ways. The center strap can have several consecutive holes in its longitudinal direction and, depending on the desired length, can optionally be buttoned onto one of these holes on the helmet. A better and therefore preferred embodiment within the scope of the invention, however, is characterized in that for the connection of the central belt to the helmet, three slots are provided which run parallel to one another and transversely to the apex plane and which are passed through one after the other by the central belt to form a loop which moves under tension automatically tighten the center belt in the slots. Such a connection enables the length of the center belt to be continuously adjusted and does not require any further fastening parts on the helmet for connecting the center belt. Altogether, therefore, a connection option for the center strap that is only slightly bulky across the helmet shell, that is to say in the direction of its thickness, is created. Of course, the length of the slots is only equal to the width of the central belt, so that the central belt cannot slip in the slots transverse to its longitudinal direction.
Beide Gabelriemen besitzen im allgemeinen jeweils vom Mittelriemenanschluß bis zum schläfenseitigen Helmanschluß gleiche Länge und sind im Schläfenbereich bezüglich dieser Länge unverstellbar an den Helm angeschlossen. Sollte aber aus dem einen oder anderen Grunde auch eine Verstellung der Gabelriemenlänge jeweils zwischen den schläfenseitigen Helmanschlußpunkten und dem Gabelriemenanschluß am Mittelriemen gewünscht oder gefordert werden, so kann dem unschwer dadurch Rechnung getragen werden, daß die Gabelriemen im Schläfenbereich längenverstellbar an den Helm angeschlossen sind, wozu wiederum der Helm für jeden Gabelriemen drei zueinander und zur Riemenlängsrichtung quer verlaufende Schlitze aufweist, die vom Gabelriemen nacheinander unter Bildung einer Schlaufe durchlaufen sind, die sich unter Zug auf den Gabelriemen selbsttätig in den Schlitzen festzieht. Die Gabelriemen sind dann im Ergebnis mit ihrem schläfenseitigen Ende in gleicher Weise kontinuierlich längenverstellbar am Helm befestigt wie der Mittelriemen.Both fork straps generally have the same length from the middle strap connection to the temple-side helmet connection and are not adjustable to the helmet with regard to this length in the temple area connected. However, if for one reason or another an adjustment of the fork belt length between the temple-side helmet attachment points and the fork strap connection on the center strap is desired or required, this can easily be taken into account by the fact that the fork straps in the temple area are connected to the helmet with adjustable length, for which purpose in turn, the helmet has three slots for each fork belt which are transverse to one another and to the longitudinal direction of the belt and which the fork belt has successively passed through to form a loop which automatically tightens in the slots under tension on the fork belt. As a result, the fork straps are attached to the helmet with their end on the side of the temple in the same way, continuously adjustable in length, as the center strap.

Der in der Zeichnung dargestellte Schutzhelm ist speziell für Radsportler bestimmt und besitzt eine dreiteilige Helmschale, bestehend aus zwei sich beidseits der Scheitelebene 1-1 des Helms gegenüber liegenden Seitenteilen 2 und einem die Seitenteile 2 längs des Scheitels überwölbenden Mittelteil 3. Zwischen dem Mittelteil 3 und den Seitenteilen 2 sind jeweils freie Fugen 4 vorgesehen, die das Mittelteil 3 und die Seitenteile 2 über die gesamte Länge des Mittelteils 3 voneinander trennen und es dadurch ermöglichen, das in der Scheitelebene 1-1 elastisch biegbare Mittelteil 3 im Sinne einer Änderung seiner Wölbung in der Scheitelebene zu verformen. Das bedeutet elastische Verformungen des Mittelteils 3 derart, daß sich seine beiden Endbereiche einander nähern oder voneinander entfernen, wobei im ersten Fall sich die Helmgröße verringert, im zweiten Fall vergrößert. Die seitenteile 2 und das Mittelteil 3 sind miteinander durch ein Band 5 verbunden, das ringartig in einer zur Scheitelebene 1-1 etwa senkrechten Querebene verläuft, welche durch die beiden Endbereiche des Mittelsteils 3 und durch die beiden Seitenteile 2 geht. Das Band 5 ist bezüglich seines Ringumfangs einstellbar und im jeweils gewünschten Ringumfang feststellbar. Derartige Helme sind beispielsweise aus dem DE-GM 87 02 777 bekannt und bedürfen daher hier keiner weiteren Beschreibung.The protective helmet shown in the drawing is specially designed for cyclists and has a three-part helmet shell, consisting of two side parts 2 opposite each other on the apex level 1-1 of the helmet and a central part 3 arching the side parts 2 along the apex. Between the central part 3 and the side parts 2 each have free joints 4 which separate the middle part 3 and the side parts 2 from each other over the entire length of the middle part 3 and thereby enable the middle part 3 which is elastically bendable in the apex plane 1-1 in the sense of a change in its curvature in deform the apex. This means elastic deformations of the central part 3 in such a way that its two end regions approach or move away from one another, the helmet size decreasing in the first case and increasing in the second case. The side parts 2 and the middle part 3 are connected to one another by a band 5, which runs like a ring in a transverse plane approximately perpendicular to the apex plane 1-1, which goes through the two end regions of the middle part 3 and through the two side parts 2. The band 5 is adjustable with respect to its ring circumference and can be locked in the desired ring circumference. Such helmets are known for example from DE-GM 87 02 777 and therefore do not require any further description here.
Der Schutzhelm, der selbstverständlich auch in anderer Weise ausgebildet und für andere Zwecke verwendbar sein kann, ist mit einer Gabelkinnberiemung ausgerüstet, die zwei beidseits am Schutzhelm jeweils im Bereich des Helmrandes etwa in der hinteren Helmmitte bei 6 einerseits und etwa im Schläfenbereich bei 7 andererseits angeschlossene Gabelriemen 8, 8′ umfaßt, von denen in Fig. 1 nur einer, nämlich der in der Schrägansicht vordere, vollständig dargestellt ist. Zur Gabelkinnberiemung behört weiter ein Kinnriemen 9, der beide Gabelriemen 8, 8′ verbindet und dazu an jeden Gabelriemen 8, 8′ mittels eines längs des Gabelriemens verschiebbaren Beschlages 10 angeschlossen ist. Dieser Beschlag 10 besteht aus einer Beschlagplatte mit drei Schlitzen 11, welche mit ihrer Längsrichtung so gegeneinander geneigt sind, daß der jeweils durch alle drei Schlitze 11 des Beschlags 10 laufende Gabelriemen 8, 8′ mit seinen beiden nacken- bzw. schläfenseitigen Riementeilen den für die jeweilige Gabelkinnberiemung bzw. die jeweilige Art des Schutzhelmes günstigsten Winkel 12, zumeist einen im wesentlichen rechten Winkel, einschließt. Der Kinnriemen 9 ist mit einer Schlaufe 9′ in den mittleren Schlitz jedes Beschlags 10 eingehängt, kann aber auch unmittelbar am Beschlag angenietet oder in anderer Weise angeschlossen sein. Der Kinnriemen 9 kann ein Kinnpolster 12 und ein Steckschloß 13 aufweisen, dessen beide Schloßteile in der Zeichnung offen dargestellt sind, und das es in einfacher Weise ermöglicht, den Kinnriemen 9 zu schließen bzw. zu öffnen. Schutzhelme mit Gabelkinnberiemungen dieser Art sind aus dem DE-GM 83 06 006 bekannt und bedürfen daher ebenfalls hier keiner weiteren Beschreibung.The protective helmet, which can of course also be designed in a different way and can be used for other purposes, is equipped with fork chin straps, the two on both sides of the protective helmet, each in the area of the helmet rim approximately in the rear helmet center at 6 on the one hand and approximately in the temple area at 7 on the other connected
Für die Erfindung wesentlich ist, daß die beiden Gabelriemen 8, 8′ an dem vom jeweiligen Beschlag 10 abgewandten Ende ihrer nackenseitigen Riementeile miteinander und gemeinsam mit einem Mittelriemen 14 verbunden sind, der im wesentlichen in der Scheitelebene 1-1 des Helms verläuft und längenverstellbar an den Helm angeschlossen ist. Im einzelnen hängen die Gabelriemen 8, 8′ an den miteinander und mit dem Mittelriemen 14 verbundenen Enden der nackenseitigen Riementeile einstückig zusammen, wobei die beiden nackenseitigen Riementeile am Mittelriemen 14 in einer quer zum Mittelriemen 14 verlaufenden Falte 15 unter Einschluß eines Winkels 16 übereinander umgeschlagen und miteinander und mit dem Mittelriemen 14 durch Nähte 17 verbunden sind. Auch hier kann der Winkel 16 zwischen den am Mittelriemen 14 zusammentreffenden nackenseitigen Riementeile den jeweiligen Erfordernissen des Schutzhelms, seiner Art und Größe nach, optimal angepaßt gewählt werden.It is essential for the invention that the two
Zum Anschluß des Mittelsriemens 14 sind am Helm in seiner Scheitelebene 1-1 übereinander drei zueinander parallel und quer zur Scheitelebene verlaufende Schlitze 18 vorgesehen. Diese Schlitze 18 werden vom Mittelriemen 14 nacheinander unter Bildung einer Schlaufe 19 durchlaufen, wie dies insbesondere aus Fig. 1 erkennbar ist. Die Schlaufe 19 hat zur Folge, daß sich der Mittelriemen 14 unter Zug selbsttätig in den Schlitzen 18 verklemmt, also sich die eingestellte Länge des Mittelriemens 14 zwischen seinem Anschluß an die Gabelriemen 8, 8′ einerseits und an den Helm andererseits nicht ändern kann. Im übrigen besitzen beide Gabelriemen 8, 8′ jeweils vom Mittelriemenanschluß bis zum schläfenseitigen Helmanschluß 7 gleiche Länge. Im Schläfenbereich sind sie bezüglich dieser Länge unverstellbar an den Helm angeschlossen, wozu sie mit Löchern 7' oder Ösen an passenden Befestigungszapfen gehalten sind, die an der Helmschale 3 innenseitig vorgesehen sind.To connect the
