The safety strap can be worn around the nape of the neck, or include a chin piece, among other manners of construction.

Description

Diese Erfindung betrifft grundsätzlich einen Helm mit seinem zugehörigen Halteband. Helme gibt es für verschiedenste Zwecke. So tragen zum Beispiel Bauleute, Bergleute, Feuerwehrleute und Rettungstruppen spezielle Helme als Schutz vor herunterfallenden Gegenständen. Soldaten tragen seit jeher Helme in Übungen und Gefechten. Weiter gibt es eine Vielzahl von verschiedenen Spezialhelmen für sportliche Zwecke, so zum Beispiel für Eishockey-Spieler, für American-Football-Spieler, für Baseball-Spieler, für Skifahrer, Bob- und Schlittenfahrer, Radsportler, Reiter usw. usf. Sehr gebräuchlich und in vielen Ländern vorgeschrieben sind Helme für Motorradfahrer im öffentlichen Strassenverkehr. Die vorliegende Erfindung bezieht sich ganz allgemein auf Helme, denn jeder Helm muss zum Tragen am Kopf befestigt werden, damit er auch bei abrupten Kopfbewegungen einen sicheren Halt hat und im Ernstfall seine Schutzfunktion auch tatsächlich zum Tragen kommt. In der Regel ist für diese Befestigung ein zweiteiliges Halteband oder Spannband am Helm befestigt, welches in der Länge stufenweise oder stufenlos verstellbar ist, und das zum Tragen zum Beispiel mittels eines Hakens oder eines Schnappverschlusses zusammengesteckt wird. Manchmal ist ein Halte- oder Spannband vorhanden, das mit seinem Ende durch zwei auf der gegenüberliegenden Seite des Helmes vorhandene Ösen gesteckt und dann zwischen diesen beiden Ösen wieder zurückgezogen wird, sodass das Spannband in der jeweiligen angezogenen Stellung mittels Reibung gehalten wird. Andere Haltebänder werden mittels Klettverschlüssen oder Druckknöpfen gesichert.This invention basically relates to a helmet with its associated tether. Helmets are available for a variety of purposes. For example, builders Miners, firefighters and rescue forces use special helmets to protect them falling objects. Soldiers have always worn helmets in exercises and battles. There are also a variety of different special helmets for sporting purposes, for example for ice hockey players, for American football players, for baseball players, for skiers, bobsleigh and sledge riders, cyclists, Riders etc. etc. Very common and are mandatory in many countries Helmets for motorcyclists on public roads. The present invention generally refers to helmets, because every helmet has to be worn be attached to the head so that it joins even with abrupt head movements has a secure hold and, in an emergency, its protective function is actually effective is coming. As a rule, a two-part strap or is for this attachment Tension strap attached to the helmet, which lengthwise or continuously in length is adjustable, and to be carried for example by means of a hook or a Snap lock is put together. Sometimes a stop or Tension strap present, with its end through two on the opposite Inserted eyelets on the side of the helmet and then between them both eyelets is pulled back so that the strap is in the respective attracted position is held by friction. Other straps are secured with Velcro fasteners or snaps.

Herkömmliche Haltebänder sind in vielen Fällen wenig komfortabel in der Anwendung oder sie lassen sich nicht leicht oder rasch in der Länge verstellen. Das Verstellen lässt sich kaum oder nur mühsam mit einer Hand bewerkstelligen, obwohl das gerade bei Radfahrer- Kletter- Reiter- und derartigen Helmen sehr wünschbar wäre. Oftmals lässt sich das Halteband auch nicht stufenlos spannen. Conventional straps are not very comfortable to use in many cases or they cannot be easily or quickly adjusted in length. The It is difficult or difficult to adjust with one hand, although this is especially true for cyclists, climbers, riders and such helmets would be desirable. Often, the tether cannot be tensioned continuously.

Es ist daher die Aufgabe der vorliegenden Erfindung, einen Helm mit einem verstellbaren Halteband zu schaffen, welcher die aufgezeigten Probleme beseitigt. Der Helm soll rasch aufgesetzt und das Halteband oder die Haltebänder sollen rasch und komfortabel mit einer fein einstellbaren Spannkraft durch den Helmträger selbst mit einer Hand angezogen werden können. Ausserdem soll es der Helm ermöglichen, dass sein Halteband während des Tragens einhändig jederzeit mühelos und rasch enger angezogen oder gelockert werden kann. Auch das Lösen des Haltebandes, sodass der Helm ausgezogen werden kann, soll rasch und mühelos erfolgen können.It is therefore the object of the present invention to provide a helmet with an adjustable To create a tether that eliminates the problems shown. The helmet should be put on quickly and the tether or straps should quickly and comfortably with a finely adjustable tension by the helmet wearer can be tightened with one hand. In addition, it should Helmet allow his tether to be carried with one hand at all times can be tightened or loosened easily and quickly. Solving too the strap, so that the helmet can be removed, should quickly and can be done effortlessly.

Die Aufgabe wird gelöst von einem Helm mit verstellbarem Halteband, welches mittels eines einhändig bedienbaren Drehverschlusses in seiner Länge stufenlos oder in Stufen von höchstens 1.5mm verstellbar und in jeder Spannlage festhaltbar und wieder lösbar ist, und der sich dadurch auszeichnet, dass das Halteband ein Spannband ist, welches längs der Helminnenseite verläuft, wobei es mittels eines im Helmmaterial fest eingebauten Drehverschlusses spannbar und wieder entspannbar ist, indem die Seilzüge des Drehverschlusses von dessen beiden gegenüberliegenden Seiten aus auf der Helminnenseite zu Umlenkrollen oder Umlenkpunkten am Helmmaterial geführt sind und von dort aus längs des zu spannenden Bandes geführt sind.The task is solved by a helmet with an adjustable strap, which infinitely variable in length using a twist lock that can be operated with one hand or adjustable in steps of a maximum of 1.5mm and in any clamping position is firm and releasable, and which is characterized in that the Retaining strap is a strap that runs along the inside of the helmet, whereby it can be tensioned by means of a screw fastener built into the helmet material and can be relaxed again by the cables of the twist lock from the two opposite sides of it on the inside of the helmet Deflection rollers or deflection points are guided on the helmet material and from there out along the band to be tensioned.

Der fest im Helmmaterial eingebaute Drehverschluss 1 ist das Kernstück für die Realisierung eines erfindungsgemässen Helmes mit einem Helm-Spannband, das einhändig spannbar, verstellbar und wieder lösbar ist. Dieser Drehverschluss 1 besteht grundsätzlich aus einem flachen Gehäuse 6, einem auf der Oberseite des Gehäuses angeordneten, relativ dazu drehbeweglichen Drehknopf 7 sowie zwei auf gegenüberliegenden Seiten aus dem Gehäuse herausgeführten Zugseilen 8, welche mit den Spannbändern verbunden sind. Durch eine Drehantriebskonstruktion innerhalb des Gehäuses des Drehverschlusses 1 kann durch Drehen des Drehknopfes 7 das Halteband des Helmes gespannt oder gelockert werden. Mit der Drehantriebskonstruktion wird hierfür zum Beispiel eine Seilscheibe, auf welche die Seilenden aufgewickelt sind, in der einen oder anderen Richtung gedreht, so dass durch eine entsprechende Drehbewegung des Drehknopfes 7 die wirksame Länge der Zugseile 8 in entgegengesetzten Richtungen im Sinne eines Lösens und Festziehens der genannten Spannbänder 3 und damit des Haltebandes veränderbar ist.The screw cap 1 built into the helmet material is the centerpiece for the Realization of a helmet according to the invention with a helmet strap, the can be tensioned, adjusted and released with one hand. This twist lock 1 basically consists of a flat housing 6, one on the top of the Housing arranged, relatively rotatable rotary knob 7 and two pulling cables 8 led out of the housing on opposite sides, which are connected to the straps. Through a rotary drive construction inside the housing of the twist lock 1 can be turned of the knob 7, the tether of the helmet can be tightened or loosened. With the rotary drive construction, for example, a rope pulley is opened which the rope ends are wound, rotated in one direction or the other, so that by a corresponding rotary movement of the knob 7 effective length of the pull cables 8 in opposite directions in the sense of a Loosening and tightening of the mentioned straps 3 and thus the tether is changeable.

Solche Drehverschlüsse 1 können in verschiedenen Konstruktionen zum Einsatz kommen. Eine mögliche Konstruktion wird nachfolgend anhand der in Figur 1 dargestellten auseinandergezogenen Vertikalschnittansicht beschrieben. Von unten beginnend ist zunächst das flache Gehäuse 6 des Drehverschlusses 1 gezeigt, das eine in der Draufsicht kreisförmige Ausdrehung 12 aufweist, in die eine darüber dargestellte Seilscheibe 13 mit Umfangsnut 16 einpasst. In diese Ausdrehung 12 münden an etwa diametral gegenüberliegenden Stellen Führungskanäle 14 durch welche die entsprechenden Enden der Zugseile 8 auf gegenüberliegenden Seiten aus dem Gehäuse 6 herausgeführt sind. Die Seilscheibe 13 bildet auf ihrer Oberseite ein Malteserkreuz mit um den Umfang verteilt angeordneten radialen Führungsnuten 17, die als Antriebselemente wirken, wie das noch klar wird. Koaxial zur geometrisch vertikalen Hauptachse 1a des ganzen Drehverschlusses 1 ist etwas oberhalb der Seilscheibe 13 eine Antriebsscheibe 18 im Gehäuse 6 angeordnet, die als Treiberscheibe mit aussermittig angeordneten Antriebszapfen 19 versehen ist, die einander etwa diametral gegenüberliegen und von der Unterseite der Antriebsscheibe 18 nach unten gegen die Seilscheibe 13 hin vorstehen. Beim zusammengebauten Drehverschluss greifen diese Antriebszapfen 19 in die radialen Führungsnuten 17 am Malteserkreuz ein, wodurch ein Malteserkreuzgetriebe gebildet ist, durch das bei einer Drehbewegung der Antriebsscheibe 18 die Antriebszapfen 19 nacheinander mit den in Umfangsrichtung aufeinanderfolgenden Führungsnuten 17 der als Malteserkreuzscheibe ausgebildeten Seilscheibe 13 in Eingriff kommen und dadurch die Seilscheibe antreiben, wodurch die Seilenden auf die Seilscheibe 13 aufgewickelt werden und das Halteband am Helm zusammenziehen. Bei umgekehrter Drehbewegung wird entsprechend ein Abwickeln der Zugseile bewirkt und entsprechend ein Lockern des Haltebandes. Das Gehäuse 6 mit der Seilscheibe 16 und der Antriebsscheibe 18 ist oben durch einen Deckel 22 abgedeckt, der an seiner Unterseite parallel zur vertikalen Hauptachse 1a verlaufende Befestigungszapfen 23,23a aufweist, von denen der eine Befestigungszapfen 23a gleichzeitig einen Drehlagerzapfen für die Führung und Lagerung der Seilscheibe 13 bildet. Diese Befestigungszapfen 23,23a sind von Gewindebohrungen 23' bzw. 23a' durchsetzt, in die vom Gehäuseboden 6a aus eingeführte Schrauben 24 eingeschraubt sind, sodass dadurch der Gehäusedeckel 22 über die Befestigungszapfen 23,23a lösbar mit dem Gehäuseboden 6a verbunden ist. Koaxial zur vertikalen Hauptachse 1a des Drehverschlusses 1 weist der Gehäusedeckel 22 auf seiner Unterseite eine Ausdrehung 25 zur Aufnahme der Antriebsscheibe 18 sowie eine zylindrische Lagerbohrung 26 auf, in der das untere, zylindrisch ausgebildete Ende 27a eines nach oben vorstehenden Zapfens 27 der Antriebsscheibe 18 zentrisch gelagert und geführt ist. Das obere, verjüngte Ende 27b dieses Zapfens 27 ragt über die Lagerbohrung 26 hinaus nach oben und ist mit einem Aussenvierkant versehen, wobei ausserdem zentral in diesem Zapfen 27 eine Gewindebohrung 27c vorhanden ist. In die Oberseite des Gehäusedeckels 22 ist ein Zahnring 28 mit einer Vielzahl von Eingriffzähnen 29 eingearbeitet, der Teil einer noch näher zu erläuternden Sperrklinkeneinrichtung ist. Dieser Zahnring 28 weist über den Umfang verteilte Eingriffszähne 29 auf, die der Feineinstellung des Drehverschlusses 1 dienen. Teil der genannten Sperrklinkeneinrichtung ist auch eine weiter oben dargestellte Sperrklinke 30, die nach Art eines zweiarmigen Hebels ausgebildet ist und über eine Schwenkachse 31 schwenkbar in einer angepassten, im Bereich über dem Zahnring 28 liegenden Durchgangsausnehmung 32 einer Zwischenscheibe 33 schwenkbar gehalten ist. Die Sperrklinke 30 weist in ihrem einen Hebelarm einen unteren Vorsprungszahn 30a und an ihrem anderen Hebelarm einen oberen Vorsprungszahn 30b auf. Mit dem unteren Vorsprungszahn 30a kann die Sperrklinke 30 in die Zähne 29 des Zahnringes 28 eingreifen, während der obere Vorsprungszahn 30b der Sperrklinke 30 in eine in die Unterseite des darüberliegenden Drehknopfes 7 eingearbeitete, etwa ringsektorförmige Steuerausnehmung 34 vorsteht, die an ihrem einen Ende eine rampenartig ansteigende Steuerfläche 34a aufweist. In diese kann der obere Vorsprungszahn 30b der Sperrklinke 30 eingreifen, wodurch der Drehverschluss gegen sein Lösen gesichert wird.Such twist locks 1 can be used in various constructions come. A possible construction is described below using the one shown in FIG exploded vertical sectional view described. From underneath beginning with the flat housing 6 of the twist lock 1 is shown, which has a circular recess 12 in the plan view, into the one above shown pulley 13 with circumferential groove 16 fits. In this turn 12 open at approximately diametrically opposite locations guide channels 14 through which the corresponding ends of the pull cables 8 on opposite Pages are led out of the housing 6. The rope pulley 13 forms on its top a Maltese cross arranged around the circumference radial guide grooves 17, which act as drive elements, as is clear becomes. Coaxial to the geometrically vertical main axis 1a of the entire twist lock 1 is a drive pulley 18 slightly above the pulley 13 Housing 6 arranged, which are arranged as a driver disc with off-center Drive pin 19 is provided, which are approximately diametrically opposite and from the underside of the drive pulley 18 downward against the pulley 13 stick out. When the twist lock is assembled, these drive pins engage 19 into the radial guide grooves 17 on the Maltese cross, whereby a Maltese cross gear is formed by the rotary motion of the Drive disk 18, the drive pin 19 one after the other in the circumferential direction successive guide grooves 17 of the Maltese cross plate Rope pulley 13 engage and thereby drive the rope pulley, whereby the rope ends are wound onto the pulley 13 and pull the strap on the helmet together. With reverse rotation correspondingly unwinding of the pull cables and loosening accordingly the tether. The housing 6 with the pulley 16 and the drive pulley 18 is covered at the top by a lid 22 which is parallel to the underside of the lid vertical main axis 1a extending fastening pins 23,23a, of which the one mounting pin 23a a pivot pin for the Management and storage of the pulley 13 forms. This mounting pin 23, 23a are penetrated by threaded bores 23 'and 23a' into which the Housing bottom 6a are screwed in from inserted screws 24, so that thereby the housing cover 22 releasably with the mounting pin 23,23a the housing base 6a is connected.

Die zwischen dem Drehknopf 7 und dem Gehäusedeckel 22 angeordnete Zwischenscheibe 33 ist mit der zylindrischen, zentralen Aussparung 33a in ihrer Unterseite auf einem zentralen, zylindrischen Lagervorsprung 22a an der Oberseite des Gehäusedeckels 22 frei drehbar gelagert und geführt. Sie weist ferner eine zentral zur Hauptachse 1a liegende Vierkant-Durchgangsöffnung 35 auf, in die das mit Aussenvierkant versehene obere Ende 27b der Antriebsscheibe 18 eingreift, sodass eine drehfeste Verbindung zwischen der Antriebsscheibe 18 und der Zwischenscheibe 33 gebildet ist. Die Sperrklinke 30 ist mittels zweier zu beiden Seiten angeordneter Lagersteine 36 von oben her in die Durchgangsausnehmung 32 im Zwischenring 33 eingelegt. In diese Lagersteine 36 ragen auch die Enden der Schwenkachse 31 hinein, wobei im Bereich zwischen dem einen Lagerstein 36 und der Sperrklinke 30 eine Schraubenfeder auf der Schwenkachse 31 angeordnet ist, sodass die Sperrklinke 30 mit ihrem unteren Vorsprungszahn 30a in Richtung auf die Eingriffzähne 29 des Zahnringes 28 federnd vorgespannt ist. Der mit einer deckelartigen Verbreiterung 7a versehene Drehknopf 7 deckt die Zwischenscheibe 33 oben ab, wobei ein von der Oberseite der Zwischenscheibe 33 vorstehender, zentraler, zylindrischer Lagervorsprung 33b in eine zentrale, ebenfalls zylindrische Aussparung 7b an der Unterseite des Drehknopfes 7 zwecks dessen Führung und Lagerung eingreift. Koaxial zur vertikalen Hauptachse 1a des Drehverschlusses 1 ist im Drehknopf 7 eine zentrale, abgesetzte Bohrung 38 vorgesehen, durch die eine Bundschraube 39 derart eingesetzt werden kann, dass ihr unteres Gewindeende 39a in die Gewindebohrung 27c an der Antriebsscheibe 18 eingeschraubt werden kann. Die Bundschraube 39 kann dabei eine Imbusschraube sein und vollkommen in der Bohrung 38 versenkt sein. The intermediate disc arranged between the rotary knob 7 and the housing cover 22 33 is with the cylindrical, central recess 33a in its underside on a central, cylindrical bearing projection 22a on the top of the housing cover 22 is freely rotatably supported and guided. It also has one located centrally to the main axis 1a square through opening 35 into which the upper end 27b of the drive pulley 18 provided with an external square engages, so that a rotationally fixed connection between the drive pulley 18 and the intermediate plate 33 is formed. The pawl 30 is by means of two to two Sides of bearing stones 36 into the passage recess from above 32 inserted in the intermediate ring 33. Also protrude into these jewels 36 the ends of the pivot axis 31, in the area between the one Bearing block 36 and the pawl 30 a coil spring on the pivot axis 31 is arranged so that the pawl 30 with its lower projection tooth 30a spring-loaded in the direction of the engagement teeth 29 of the toothed ring 28 is. The rotary knob 7 provided with a lid-like widening 7a covers the Washer 33 from above, one from the top of the washer 33 protruding, central, cylindrical bearing projection 33b into a central, also cylindrical recess 7b on the underside of the rotary knob 7 intervenes for the purpose of its management and storage.

The collar screw 39 can be an Allen screw and be completely sunk in the bore 38.

In der Figur 2 sind die einzelnen hier beschriebenen Teile des Drehverschlusses in zusammengebautem Zustand in einem Querschnitt dargestellt.FIG. 2 shows the individual parts of the twist lock described here shown in an assembled state in a cross section.

Bei dieser Ausführung des Drehverschlusses 1 ist femer von Bedeutung, dass der Drehknopf 7 unter Schaffung eines Leerweges begrenzt relativ drehbeweglich auf der Oberseite der Zwischenscheibe 33 gelagert und geführt ist. Zur Erzielung dieses Leerweges weist der Drehknopf 7 an seiner Unterseite, hier der Steuerausnehmung 34 diametral gegenüberliegend, einen nach unten vorstehenden Mitnehmerzapfen 40 auf, der in eine ringsektorförmige Ausnehmung 41 in der Oberseite der Zwischenscheibe 33 eingereift, und mit ihren in Umfangsrichtung weisenden Enden Anschlagenden 41a,41b bildet, wie das am besten in Figur 3 zu ersehen ist. Diese Anschlagenden 41a,41b begrenzen, wenn sie in der einen oder anderen Drehrichtung des Drehknopfes 7 mit dem Mitnehmerzapfen 40 in Anschlag kommen, den Leerweg dieses Drehknopfes 7. Dies bedeutet, dass der Drehknopf 7 bei seiner Drehbewegung in der einen oder anderen Richtung entsprechend der Länge des Leerweges begrenzt relativ frei drehbar auf und gegenüber der Zwischenscheibe 33 drehbar gelagert und geführt ist. Die Länge dieses Leerweges ist abgestimmt auf die Umfangslänge der Steuerausnehmung 34, in die der obere Vorsprungszahn 30b der Sperrklinke 30 als eine Art Steuervorsprung eingreift. Wenn dementsprechend der Drehknopf 7 in Richtung der Festzieh-Drehbewegung des Drehverschlusses 1 gedreht wird, dann bewegt sich der Drehknopf 7 zunächst alleine bzw. frei relativ zur Mitnehmerscheibe 33 so weit, bis sein Mitnehmerzapfen 40 mit dem entsprechenden Anschlagende 41a der Ausnehmung 41 in Eingriff kommt. Hierdurch gelangt der obere Vorsprungszahn 30b der Sperrklinke 30 durch die Wirkung der Federvorspannung vollkommen in die Steuerausnehmung 34, während gleichzeitig der untere Vorsprungszahn der Sperrklinke mit den Eingriffzähnen 29 des Zahnringes 28 federnd in Eingriff gedrückt wird. Bei einer weiteren Festzieh-Drehbewegung wird über das Malteserkreuzgetriebe die Seilscheibe 13 gedreht, so dass die entsprechenden Enden der Zugseile auf dieser Seilscheibe 13 aufgewickelt und somit die Spannbänder festgezogen werden. Hierbei kommt die Sperrklinke 30 nacheinander mit den in Umfangsrichtung verteilten Zähnen 29 des Zahnringes 28 in Eingriff. Nach Beendigung der Festzieh-Drehbewegung durch den Drehknopf 7 wird die dann erreichte Dreheinstellung des Drehverschlusses 1 in der Festziehlage durch die Klinkeneingriffsstellung verriegelt. Die Spannbänder des Helms können deshalb einhändig äusserst feinfühlig und millimetergenau gespannt werden. Wenn dann der Drehverschluss 1 gelöst werden soll, um die Spannbänder des Helms wieder zu öffnen, so wird der Drehknopf 7 in Richtung der Löse-Drehbewegung zurückgedreht, wodurch der Drehknopf 7 entsprechend dem Leerweg zunächst wieder alleine und frei drehbeweglich relativ zur Zwischenscheibe 33 dreht, bis sein Mitnehmerzapfen 40 die entgegengesetzte Leerweg-Endstellung am Anschlagende 41b in der Ausnehmung 41 erreicht hat. In dieser Leerweg-Endstellung hat sich gleichzeitig die rampenartig ansteigende Steuerfläche 34a über die ihm zugewandte Fläche des oberen Vorsprungszahnes 30b der Steuerklinke 30 geschoben, sodass dadurch - entgegen der Federvorspannung - der untere Vorsprungszahn 30a der Sperrklinke 30 von den Eingriffszähnen 29 des Zahnringes 28 ausser Eingriff gebracht wird. Auf diese Weise ist die Sperrklinke 30 in ihre Entriegelungsstellung gebracht worden und wird darin solange gehalten, wie der Drehknopf 7 in Richtung der Löse-Drehbewegung gedreht bzw. der Mitnehmerzapfen 40 dieses Drehknopfes 7 in der Leerweg-Endstellung gehalten wird. Die so entriegelte Sperrklinkeneinrichtung gestattet damit ein problemloses Betätigen des Malteserkreuzgetriebes in der Weise, dass die Seilscheibe 13 gedreht und dadurch die Zugseile 8 von dieser Seilscheibe 13 wieder abgewickelt werden können. Die Zugseile können auf jeder Seite des Drehverschlusses als Schlaufe ausgebildet sein, sodass also das eine Schlaufenende fest am Drehverschluss befestigt ist und das andere um die Seilscheibe aufgewickelt ist. Die Schlaufe ist dann um eine lose Rolle geführt, die am Ende eines Spannbandes sitzt. Durch Auf- oder Abwickeln des freien Schlaufenendes werden dann die Spannbänder des Helms zusammengezogen oder gelockert. In this embodiment of the twist lock 1 it is also important that the Knob 7 limited to create a free travel relatively rotatable the top of the intermediate plate 33 is mounted and guided. To achieve This free travel has the knob 7 on its underside, here the control recess 34 diametrically opposite, one protruding downward Driver pin 40, which in a ring sector-shaped recess 41 in the Top of the intermediate plate 33 ripened, and with their in the circumferential direction pointing ends forms stop ends 41a, 41b, as best shown in FIG is seen. These stop ends 41a, 41b limit when in one or the other other direction of rotation of the knob 7 with the driver pin 40 in Come stop, the free travel of this knob 7. This means that the Rotary knob 7 correspondingly when it rotates in one direction or the other the length of the free travel is relatively freely rotatable on and opposite the intermediate disc 33 is rotatably supported and guided. The length of this Free travel is matched to the circumferential length of the control recess 34, into which the upper projection tooth 30b of the pawl 30 as a kind of control projection intervenes. Accordingly, the knob 7 in the direction of the tightening rotation of the screw cap 1 is rotated, then the Rotary knob 7 initially alone or freely relative to drive plate 33 so far, until its driver pin 40 with the corresponding stop end 41a Recess 41 comes into engagement. This will get the upper protrusion tooth 30b of the pawl 30 completely in by the action of the spring preload the control recess 34, while the lower projection tooth of the Pawl with the engagement teeth 29 of the toothed ring 28 pressed resiliently into engagement becomes. With a further tightening rotary movement, the Maltese cross gear the pulley 13 rotated so that the corresponding ends of the Traction ropes wound on this pulley 13 and thus the straps be tightened. Here, the pawl 30 comes in succession with the in Circumferentially distributed teeth 29 of the toothed ring 28 in engagement. After completion the tightening rotary movement by means of the rotary knob 7 is then achieved Rotary adjustment of the screw cap 1 in the tightened position by the Latch engaged position locked. The straps of the helmet can therefore be tensioned with one hand, extremely sensitive and with millimeter precision. If then the twist lock 1 is to be released to the straps of the helmet again to open, the rotary knob 7 is turned back in the direction of the release rotary movement, whereby the knob 7 corresponding to the free travel initially again alone and freely rotatable relative to the intermediate disc 33 until its driver pin 40 the opposite free travel end position at the stop end 41b has reached in the recess 41. In this empty travel end position at the same time the control surface 34a, which rises like a ramp, via the control surface facing it Surface of the upper projection tooth 30b of the control pawl 30 pushed, so that - against the spring preload - the lower projection tooth 30a of the pawl 30 from the engagement teeth 29 of the ring gear 28 is disengaged. In this way, the pawl 30 is in their Unlocked position has been brought and is held in it as long as the Turn knob 7 in the direction of the release rotary movement or the driver pin 40 of this knob 7 is held in the free travel end position. The so unlocked pawl device thus allows easy operation of the Maltese cross gear in such a way that the pulley 13 rotated and thereby the traction ropes 8 can be unwound from this sheave 13. The pull cables can be designed as a loop on each side of the twist lock so that one end of the loop is firmly attached to the twist lock and the other is wrapped around the sheave. The loop is then led around a loose roll that sits at the end of a tension band. By or unwinding the free end of the loop are then the straps of the Helms contracted or loosened.

Die Figur 4 zeigt eine Ausführung eines Baseball-Helmes 80 von hinten her gesehen. Hier ist der Drehverschluss 1 in die Kunststoff-Schale des Helmes 80 eingebaut und das Halteband 84 verläuft horizontal zwischen der Ausnehmung im hinteren Teil der Kunststoff-Schale. Das Spannen erfolgt über je ein Seil 85,86, das von beiden Seiten des Drehverschlusses 1 nach aussen hin zu Umlenkrollen 87 führt, und von dort zurück an je ein Ende des Haltebandes 84. Zwischen dem Drehverschluss 1 und den Umlenkrollen 87 ist das Seil in einem längs der Helminnenseite verlaufenden Führungskanal geführt. Sowohl das Halteband 84 wie auch der Drehverschluss 1 und seine Kabel 85,86 können von innen her mit einem Schaumstoff-Abschnitt abgedeckt sein, sodass keine Druckstellen am Kopf des Helmträgers entstehen.FIG. 4 shows an embodiment of a baseball helmet 80 seen from behind. Here, the screw cap 1 is built into the plastic shell of the helmet 80 and the tether 84 runs horizontally between the recess in the rear part of the plastic shell. Tensioning is carried out via a rope 85.86, that from both sides of the twist lock 1 to the outside towards pulleys 87 leads, and from there back to one end of the tether 84. Between the Twist lock 1 and the pulleys 87 is the rope in a along the Guide channel running inside the helmet. Both the tether 84 as well as the twist lock 1 and its cables 85, 86 can be used from the inside a foam section so that there are no pressure points on the head of the helmet wearer arise.

In Figur 5 ist ein Radfahrerhelm in einem Schnitt längs seiner Längsachse von der Seite her gesehen gezeigt. Die Helmvorderseite befindet sich dabei auf der linken Blattseite und die Rückseite des Helmes auf der rechten Blattseite. Der Helm besteht aus einem Vollmaterial 90, in welches hier auf der Helmrückseite ein Drehverschluss 1 eingebaut ist, indem dieser auf einem konischen Einlageteil 97 sitzt, das in eine am Helmmaterial 90 vorhandene Aussparung einpasst. Auf der Helminnenseite ist eine T-förmige Lasche 91 angeordnet, wobei jedoch das T gestürzt ist. Diese Lasche 91 ist an der Helminnenseite an der Stelle 92 befestigt. Ihr T-Balken bildet das eigentliche Spannband, das um den Nackenbereich des Helmträgers verläuft Von diesem T-Balken ist in der gezeigten Schnittdarstellung allerdings nur der eine Teil 93 sichtbar. Längs dieses T-Balkens bzw. längs des Spannbandes verläuft der Seilzug 8, welcher eine Schlaufe bildet, die um eine Umlenkrolle 94 geführt ist, die von der Helminnenseite her in das Helmmaterial eingelassen ist. Es kann sich dabei um eine drehbar gelagerte Umlenkrolle handeln, oder auch nur um einen festen Kunststoff-Nocken mit Umfangsnut, in welche die Schlaufe des Seilzuges 8 eingelegt ist. Das Ende des einen Seiles ist fest mit dem T-Balken-Teil 93 der Lasche 91 verbunden, während das Seil mit seinem anderen Ende zum Drehverschluss 1 führt, wo es in mehrfach beschriebener Weise in den Drehverschluss 1 einziehbar und entweder in Stufen oder stufenlos feststellbar und somit spannbar ist. Umgekehrt ist es vom Drehverschluss durch Drehen des Drehknopfes 7 in umgekehrter Richtung wieder freigebbar und somit ist die Spannung lösbar. Der Drehknopf 7 weist hier spezielle Flügelrippen 95 auf, sodass er trotz seiner im Helm eingelassenen Einbauart auch mit Handschunen mühelos drehbar ist. Zum Anziehen dieses Radfahrerhelmes muss dieser bloss noch über den Kopf gestülpt werden und hernach muss durch Drehen des Drehknopfes 7 das durch den T-Balken 93 der aufgehängten Lasche 91 gebildete Spannband angezogen werden. Es legt sich dabei um den Nackenbereich des Helmträgers, während der Helm mit seiner vorderen Innenseite gegen die Stirn des Helmträgers gespannt wird, was den Gegendruck erzeugt, damit der Helm sicher am Kopf gehalten ist. Die Spannung lässt sich sehr fein dosieren und auch während der Fahrt mühelos einhändig verstellen.In Figure 5 is a cyclist helmet in a section along its longitudinal axis of the Seen from the side. The front of the helmet is on the left Blade side and the back of the helmet on the right blade side. The helmet is there made of a solid material 90, in which here a screw cap on the back of the helmet 1 is installed by sitting on a conical insert 97 that fits into a recess on helmet material 90. On the A T-shaped tab 91 is arranged on the inside of the helmet, but the T is overturned is. This tab 91 is attached to the inside of the helmet at point 92. you T-bar forms the actual tension band, which is around the neck area of the Helmet wearer runs from this T-beam is in the sectional view shown however only part 93 is visible. Along this T-bar or along the Tension band runs the cable 8, which forms a loop around a Deflection roller 94 is guided from the inside of the helmet into the helmet material is let in. It can be a rotatably mounted deflection roller, or just around a solid plastic cam with a circumferential groove into which the loop of the cable 8 is inserted. The end of one rope is fixed with connected to the T-beam part 93 of the tab 91, while the rope with his other end leads to the twist lock 1, where it is described in several Retractable in the twist lock 1 and either in steps or continuously is ascertainable and therefore exciting. Conversely, the screw cap is through Turning the rotary knob 7 in the opposite direction can be released again and thus the tension can be released. The rotary knob 7 here has special wing ribs 95, so that despite its installation method embedded in the helmet, it can also be used with handshakes is easily rotatable. To put on this cyclist's helmet, you just have to still to be put over the head and then by turning the Knob 7 that formed by the T-beam 93 of the suspended tab 91 Tightening strap. It wraps around the neck area of the Helmet wearer while the front of the helmet is against the forehead the helmet wearer is tensioned, which creates the back pressure, so the helmet is held securely on the head. The tension can be dosed very finely and also can be easily adjusted with one hand while driving.

Die Figur 6 zeigt eine weitere Ausführung eines Radfahrerhelmes. Dieser stimmt im wesentlichen mit dem oben beschriebenen überein, ausser dass er ohne aufgehängte Lasche auskommt. Das Spannband 96 wir hier vom Seilzug 8 selbst gehalten. Hierfür weist es zwei längs des Spannbandes 96 verlaufende flexible Führungsröhrchen auf, die fest mit dem Spannband 96 verbunden sind, oder es besteht direkt aus einem Profilband, welches solche Führungsröhrchen einschliesst, durch die dann die Seile 8 eingezogen sind. Vorzugsweise läuft das Seil also zunächst, wenn man den Helm von hinten betrachtet, entgegen der Spannrichtung aus dem Drehverschluss 1 heraus und dann unten längs in das Spannband 96 hinein, oder in das Röhrchen am Spannband 96, und verläuft nahe am unteren Rand des Spannbandes 96 bis zu dessen einem Ende. Von dort führt das Seil 8 weiter um die Umlenkrolle 94 auf dieser Helmseite. Anschliessend führt es zurück zum Spannband und in diesem bzw. im zugehörigen Führungsröhrchen längs des oberen Randes in dessen Nähe bis zum anderen Ende des Spannbandes, von dort um die Umlenkrolle auf der anderen Helmseite und schliesslich wiederum in einem Führungsröhrchen längs des unteren Spannbandrandes zurück zum Drehverschluss 1. FIG. 6 shows a further embodiment of a cyclist's helmet. This is correct essentially the same as described above, except that it is not hung Tab comes out. The strap 96 we here from the cable 8 itself held. For this purpose it has two flexible ones running along the tensioning band 96 Guide tubes, which are fixedly connected to the strap 96, or it consists directly of a profile tape, which includes such guide tubes, through which the ropes 8 are then drawn. The rope preferably runs So first, if you look at the helmet from behind, against the direction of tension out of the screw cap 1 and then lengthways into the tensioning band 96, or into the tube on the strap 96, and runs close to lower edge of the tensioning strap 96 to one end thereof. That leads from there Rope 8 continues around the pulley 94 on this side of the helmet. Then it leads back to the strap and in this or in the associated guide tube along the top edge near to the other end of the strap, from there around the pulley on the other side of the helmet and finally again in a guide tube along the lower edge of the strap for twist lock 1.

In Figur 7 ist der Radfahrerhelm gemäss der Figur 6 noch in einer Ansicht von unten dargestellt. Man erkennt das Spannband 96 und den darunter im hinteren Teil des Helmmaterials 90 angeordneten Drehverschluss 1. Die Seilschlaufen 8 führen an beiden Helminnenseiten um dort angeordnete Umlenkpunkte. Dieser Radfahrerhelm ist somit kompakt und das Spannband ist formschön und ohne störend herauszuhängen in das Helminnere integriert.In Figure 7, the cyclist helmet according to Figure 6 is still in a view from shown below. You can see the strap 96 and the one below it in the rear Part of the helmet material 90 arranged twist lock 1. The rope loops 8 lead around the deflection points on both sides of the helmet. This Cyclist's helmet is therefore compact and the strap is shapely and without hanging out integrated into the inside of the helmet.

Es versteht sich, dass verschiedenste Helme mit dem grundsätzlichen System ausgerüstet sein können, wonach das Halteband direkt oder indirekt mittels eines solchen Drehverschlusses 1 verstellbar und in der jeweiligen Spannlänge fixierbar ist. Der Drehverschluss 1 kann auch an anderer Stelle am Helm montiert sein, zum Beispiel vorne oder an der Seite. Seine Kabel sind dann längs der Helmschale so geführt, dass sie das Halteband, wo immer es auch verläuft, nach Belieben spannen können.It goes without saying that various helmets with the basic system can be equipped, after which the tether directly or indirectly by means of a such twist lock 1 adjustable and fixable in the respective span is. The twist lock 1 can also be mounted elsewhere on the helmet, for example at the front or on the side. His cables are then along the helmet shell guided so that the strap, wherever it runs, after Can stretch at will.
