Abstract

Conventional protective helmets for motor cycles and the like consist of an outer plastic shell (1), with shock-absorbing material (2) and an inner textile lining (4) below it; furthermore, they usually have a single-piece chin protection strap which is rigid or removable or can be swivelled upwards. The invention described here additionally has a gas cushion between the shock-absorbing layer (2) and the textile layer (4). The cushion is produced by an elastic, single- or multi-part sack (3) which is filled with gas and the volumetric content of which may be variable for the user by means of a pump (5) and valves (6) (7) accommodated in the helmet; or an air cushion is produced due to the dynamic pressure of the travelling wind which enters at the front side of the helmet under the textile layer (4) and is conducted off again at the rear side; thus by means of a correspondingly porous inner textile lining (4) the air flow can be used for air conditioning of the helmet. A chin protection strap (12) (13) which is movable, even gripping below the lower jaw, can be used, the closure of which sets the pump mechanism in motion when the helmet has been put on. <IMAGE>

Description

Es dreht sich um Motorrad- und ähnliche Schutzhelme mit, - auch benutzervariablem oder klimatisierendem - , Gaspolster und kinnuntergreifendem, beweglichem Kinnschutz-Bügel.It is about motorcycle and similar helmets with, - also user-variable or air-conditioning -, gas cushion and chin-reaching, movable chin guard strap.

§ 1 MOTORSPORTHELM MIT BENUTZERVARIABLEM LUFTPOLSTER NACH PATENTANSPRUCH NR.3; EINE GEWERBLICHE ANWENDUNG§ 1 MOTOR SPORTS HEAD WITH USER-VARIABLE AIR PAD ACCORDING TO CLAIM NO.3; A COMMERCIAL APPLICATION § 1.1 KURZBESCHREIBUNG§ 1.1 SHORT DESCRIPTION

Der hierin beschriebene Helm mit einstellbarem Luftpol­ster unterscheidet sich vom derzeitigen Helm durch ein zusätzliches, einfaches, pneumatisches System, das Schutzhelme, insbesondere jede Art von Motorradhelmen, verbessert, sowohl in puncto Sicherheit, vor allem aber hinsichtlich des Tragekomforts.The adjustable-air-helmet helmet described herein differs from the current helmet by an additional simple pneumatic system that improves safety helmets, particularly any type of motorcycle helmets, in terms of both safety and, above all, comfort.

Bild 1 zeigt den nicht maßstabsgetreuen Längsschnitt des luftgepolsterten Helmes; Textilgewebe (4) und Luft­polstersack (3) sind im Verhältnis zur Dicke der rest­lichen Helm-Teile vergrößert gezeichnet.Figure 1 shows the non-scale longitudinal section of the air-cushioned helmet; Textile fabric (4) and air cushion bag (3) are drawn in relation to the thickness of the remaining helmet parts enlarged.

Bild 2 erläutert den Aufbau der Pneumatik mit Pumpe (5), Luftsack (3), Sperr-Ventil (7) und Regulier-­Ablaß-Ventil (6).Figure 2 explains the structure of the pneumatics with pump (5), air bag (3), blocking valve (7) and regulating drain valve (6).

Zum System gehören ein Luftsack (3), der sich unter der Textilinnenlage (4) des Helmes befindet sowie eine manuelle Luftpumpe (5) und ein ebenfalls handbetätigtes Entlüftungsventil (6); die letzten beiden sind im Kinn­ bereich untergebracht. Die einzelnen pneumatischen Bau­teile sind durch Schlauchleitungen miteinander verbunden. Aufgesetzt wird der Helm im entlüfteten Zustand, dann kann mittels Luftpumpe per Daumendruck der Luftsack auf­geblasen werden, bis sich im Sack (3) zwischen Kopf und Helm ein bequemes Luftpolster bildet. Vor dem Abnehmen wird das Entlüftungs-Ventil (6) geschaltet und so der Luftsack (3) bis auf Normalluftdruck entleert. Ansonsten entspricht der Helm dem Stand der Technik: d.i. eine feste Kunststoffaußenschale (1) und darin eingebettet das Stoßdämpfmaterial (2).The system includes an air bag (3), which is located under the textile inner layer (4) of the helmet and a manual air pump (5) and also a manually operated vent valve (6); the last two are in the chin housed area. The individual pneumatic components are connected to each other by hose lines. The helmet is put on in the vented state, then the airbag can be inflated by means of a thumb pump by means of an air pump until a comfortable air cushion forms in the bag (3) between the head and the helmet. Before removing the vent valve (6) is switched and so the air bag (3) emptied to normal air pressure. Otherwise, the helmet corresponds to the prior art: di a solid plastic outer shell (1) and embedded therein the Stoßdämpfmaterial (2).

§ 1.2 VORTEILE§ 1.2 BENEFITS

Die Vorteile der Erfindung bestehen im höheren Komfort
- wg. größerer Auflagefläche zwischen Helm und Kopf, dadurch geringerer Druck auf einzelne Kopf-Partien (Schläfen, Ohren);
- durch leichteres Aufsetzen und Abnehmen des ent­lüfteten Helms, besonders für Brillenträger;
und größerer Sicherheit
- wg. geringerer Gefahr des gewaltsamen Motorradhelm-­Abziehens im Falle eines Sturzes durch die Aufprall­kraft (9): erstens, wegen besserer Passung Helm/Kopf; zweitens, weil die Ausdehnung (8) des Luftpolstersacks einem Herunterschieben des Helms entgegen wirkt;
- da ein entlüfteter Luftpolster-Helm in den Innenmaßen größer ausfällt und so einem Verletzten leichter abge­nommen werden kann;
- bedingt durch gleichmäßigere Kraftverteilung am Kopf, bei Sturz, durch größere Kontaktfläche Helm / Kopf.The advantages of the invention are the higher comfort
- wg. larger contact surface between helmet and head, thus less pressure on individual head parts (temples, ears);
- by easier putting on and taking off the ventilated helmet, especially for spectacle wearers;
and greater security
- wg. lower risk of violent motorcycle helmet removal in the event of a fall by the impact force (9): first, because of better fit helmet / head; second, because the expansion (8) of the air cushion bag counteracts pushing down of the helmet;
- As a vented air cushion helmet fails in the internal dimensions larger and so an injured can be easily removed;
- due to more even force distribution on the head, in case of fall, through larger contact surface helmet / head.

Bild 3 zeigt das Verhalten des Luftpolstersacks (3) bei Krafteinwirkung (9) im Vorderkopf-Bereich und Pumpe (5).Figure 3 shows the behavior of the air cushion bag (3) when force (9) in the forehead area and pump (5).

Ob der Komfortgewinn oder das Plus an Sicherheit höher einzuschätzen ist, hängt wesentlich von der Auslegung des Luftsacks ab; je geringer Volumen und Druck im Luftsack sind, desto mehr tritt der Sicherheitsvorteil in den Hintergrund.Whether the gain in comfort or the additional safety is to be estimated higher depends essentially on the design of the airbag; the lower the volume and pressure in the airbag, the more the safety advantage fades into the background.

§ 1.3 NÄHERE BETRACHTUNGEN§ 1.3 DETAILED VIEWS § 1.3.1 Volumen und Druck im System§ 1.3.1 Volume and pressure in the system

Bei einem max. Helmgewicht von 2 [kg] und einer Auflage­fläche von ca. 200 [cm^2] errechnet man einen Überdruck von 1000 [Pa] (0,01 [bar]), der nötig ist den Helm vom Kopf anzuheben; wird der Fahrtwind, der auf die ent­sprechend kleinere Stirnfläche wirkt, und die Kraft zur elastischen Dehnung des Luftsackes mitberücksichtigt, erhält man einen Druck von ca. 1,15 * 10^5 +- 10^4 [Pa] (1,15 +- 0,1 [bar]), der im Luftsack herrschen sollte.At a max. Helmet weight of 2 [kg] and a bearing surface of about 200 [cm ^ 2], it is calculated an overpressure of 1000 [Pa] (0.01 [bar]), which is necessary to lift the helmet from the head; if the airstream acting on the correspondingly smaller face and the force for elastic stretching of the airbag are taken into account, a pressure of approximately 1.15 * 10 ^ 5 + - 10 ^ 4 [Pa] (1.15 + - 0.1 [bar]), which should prevail in the airbag.

Die Helminnenfläche beträgt ca. 600 [cm^2]. Unterscheidet man zwischen günstigen Zonen, wo der Helm großflächig aufliegt (Kopfoberseite, Hinterkopf, Stirn) und Problem­bereichen, bei denen der herkömmliche Helm nur geringe Auflageflächen aufweist (Ohren, Schläfen, Nacken), so kommt man auf ca. 400 [cm^2] günstige und ca. 200 [cm^2] problematische Zonen.
Werden die schwierigen Kopfpartien mit 6 [mm] Luftschicht umpolstert und die einfacheren mit 2 [mm], ergibt sich für das Gesamtluftvolumen im Sack rund 200 [cm^3]. Dieser Wert kann selbstverständlich entsprechend der Bau­art des Helms und der Kopfform schwanken; als oberer Richtwert für die konstruktive Auslegung der einzelnen System-Bauteile mag er so hingehen.
Tatsächlich reicht ein Luftpolster mit einer durch­ schnittlichen Dicke von einem Millimeter schon aus, um die Auflagefläche des Helms am Kopf um ein Mehrfaches zu vergrößern und so den Druck auf besonders belastete Kopf­bereiche merklich zu verringern.
Die Druckschwankungen im Sack, bedingt durch auftretende Temperaturunterschiede , bei 30 [Grad C] immerhin ca. 10 [%], werden, soweit sie nicht schon von allein durch entsprechende Volumenänderungen des Luftsacks kompensiert wurden, durch Pumpen bzw. Entlüften von Hand ausgeglich­en.The helmet surface is about 600 [cm ^ 2]. If one differentiates between favorable zones where the helmet rests on a large area (top of the head, back of the head, forehead) and problem areas where the conventional helmet has only small support surfaces (ears, temples, neck), then one arrives at about 400 [cm ^ 2] cheap and about 200 [cm ^ 2] problematic zones.
If the difficult head sections are padded with 6 [mm] air layer and the simpler ones with 2 [mm], the total air volume in the bag is around 200 [cm ^ 3]. This value may of course vary according to the design of the helmet and the head shape; he may go this way as the upper benchmark for the structural design of the individual system components.
In fact, an air cushion suffices with one average thickness of one millimeter, in order to increase the support surface of the helmet at the head many times and thus significantly reduce the pressure on particularly stressed head areas.
The pressure fluctuations in the bag, due to occurring temperature differences, at 30 [degrees C] after all about 10 [%], are compensated by pumping or venting by hand, as far as they were not compensated by alone by corresponding volume changes of the airbag.

§ 1.3.2 Die Pumpe§ 1.3.2 The pump

Sie besteht im einfachsten Fall aus einem Gummikörper (5) mit einem Anschluß zum Luftsack (3). Durch Zusammen­drücken des Gummiballs (5) mit den Daumen strömt Luft über ein Ventil (7) in den Sack (3). Der zusammengepreßte Gummikörper wird über ein weiteres Ventil (in Bild 2 nicht eingezeichnet, da zur Pumpe gehörig), das durch den nun herrschenden Unterdruck im Gummiball öffnet, für den nächsten Pumpvorgang wieder belüftet; man denke sich eine verkleinerte Luftmatratzen-Pumpe.It consists in the simplest case of a rubber body (5) with a connection to the airbag (3). By compressing the rubber ball (5) with the thumb air flows through a valve (7) in the bag (3). The compressed rubber body is vented via another valve (not shown in Figure 2, as belonging to the pump), which opens by the now prevailing negative pressure in the rubber ball, re-pumped for the next pumping operation; think of a downsized air mattress pump.

Die Größe und damit die Leistungsfähigkeit der Pumpe sind durch das Raumangebot im Kinnschutz des Helmes begrenzt; 40 [cm^3] Fördervolumen pro Pumpintervall sind jedoch durchaus zu verwirklichen, sodaß das Aufpumpen nur wenige Sekunden in Anspruch nimmt.The size and thus the performance of the pump are limited by the space available in the chin guard of the helmet; 40 [cm ^ 3] delivery volume per pumping interval, however, are quite feasible, so that the pumping takes only a few seconds.

§ 1.3.3 Der Luftsack§ 1.3.3 The airbag

Er (3) kann aus einem Stück oder aus mehreren Einzel­teilen, die durch Schlauchleitungen verbunden sind, be­stehen. Bei entsprechender Ausführung im Kinnbereich, - der Sack (3) untergreift teilweise die Kinnlade -, kann auf einen üblichen Kinnriemen verzichtet werden. Außer Luftdichtigkeit und genügend Dauer-Elastizität werden an das Material des Luftsacks kaum Anforderungen gestellt, da die mechanischen Belastungen gering aus­fallen. Allerdings hängt viel vom Elastizitäts-Modul des verwendeten Werkstoffs ab (Gummi, Kautschuk) : verformt er sich gar zu leicht, kann kein Druck aufgebaut werden, stattdessen quillt der Sack unter dem Helm hervor; ist der Luftsack zu schwer elastisch verformbar, erzielt man gegenüber dem Normal-Helm kaum Komfortvorteile, da sich dann, trotz hohem Druck, der Luftsack nicht genügend der Kopfkontur anpasst.
Gegen Abrieb ist der Sack zum Kopf hin mit einem Textil­gewebe geschützt (4).
Bereiche des Kopfes unter deren Haut größere Adern liegen (Teile der Schläfen, vor und unterhalb der Ohren, Teile des Nackens) dürfen entweder vom Luftsack nicht überdeckt werden, - aus medizinischen Erwägungen -, oder besser: der Sack wird so gestaltet, daß er an diesen Stellen eine hinreichende Mulde aufweist.He (3) may consist of one piece or of several individual parts which are connected by hose lines. With appropriate execution in the chin area, - the bag (3) engages under the jaw partially - can be dispensed with a usual chin strap. Apart from airtightness and sufficient permanent elasticity hardly any requirements are placed on the material of the airbag, since the mechanical loads are low. However, much depends on the modulus of elasticity of the material used (rubber, rubber): if it deforms too easily, no pressure can be built up, instead the bag swells under the helmet; If the airbag is too difficult to deform elastically, you will hardly achieve any comfort advantages over the normal helmet, because then, despite high pressure, the airbag does not adequately adapt to the contour of the head.
Against abrasion, the bag is protected to the head with a textile fabric (4).
Areas of the head under whose skin there are larger veins (parts of the temples, in front of and below the ears, parts of the neck) may either not be covered by the airbag, - for medical reasons - or, better, the sack is designed to fit has a sufficient depression in these places.

Bild 4 zeigt schraffiert die Stellen am Kopf, die luftge­polstert sind (10).Figure 4 shows hatched areas on the head, which are air-cushioned (10).

§ 1.3.4 Die Ventile§ 1.3.4 The valves

Das Ventil (7) zwischen Luftsack (3) und Pumpe (5) öffnet durch Druckbeaufschlagung von der Pumpe her; um den Druck im Sack genügend fein dosieren zu können, muß das Ventil schon bei geringem Überdruck sicher schalten (bei ca. 10^3 [Pa] Druckdifferenz zwischen Ventil-Ein- und Ausgang). In Richtung Pumpe ist das Ventil (7) natürlich nicht durchlässig.The valve (7) between air bag (3) and pump (5) opens by pressurizing the pump; In order to be able to dose the pressure in the bag sufficiently finely, the valve must switch safely even at a slight overpressure (at approx. 10 ^ 3 [Pa] pressure difference between valve inlet and outlet). In the direction of the pump, the valve (7) is of course not permeable.

Ein weiteres Ventil (6) dient der vollständigen Entlüft­ ung des Luftsacks, - zum Helmabnehmen -, wie auch der teilweisen Entlüftung, - zur Druckfeineinstellung. Da für letzteres kleine Drücke regelbar sein müssen, anderer­seits das vollständige Entlüften bis auf Normalluftdruck möglichst rasch ablaufen soll, wird das Ventil mindestens zweistufig ausgelegt (z.B. als Taster: Taste mit leichtem Fingerdruck angetippt -> Feineinstellung; Taste mit stärkerem Fingerdruck betätigt -> Totalentlüftung).Another valve (6) is used for complete venting of the airbag, - to remove the helmet - as well as the partial venting, - to fine adjustment. Since for the latter small pressures must be controllable, on the other hand, the complete venting should proceed as quickly as possible to normal air pressure, the valve is designed at least two stages (eg as a button: touched with a light touch finger -> fine adjustment, button with stronger finger pressure actuated -> total ventilation) ,

Um ein unsinniges, übermäßiges Aufpumpen, und damit eventuelle Schäden des Systems auszuschließen, kann ein gesondertes Überdruck-Sicherheitsventil eingebaut werden, zwischen Ventil (6) und (7), das bei einem zulässigen Maximaldruck von ca. 1,2 * 10^5 +- 10^4 [Pa] selbsttätig öffnet, oder, um mit möglichst wenig Bau­teilen auszukommen, gestaltet man das schon vorhandene Luftablaß - Ventil (6) so, daß es die Sicherheitsfunktion bez. zu hohen Drucks, mitzuübernehmen in der Lage ist.To avoid nonsensical, excessive inflating, and thus possible damage to the system, a separate overpressure safety valve can be installed, between valve (6) and (7), which at a maximum allowable pressure of about 1.2 * 10 ^ 5 + - 10 ^ 4 [Pa] opens automatically, or, in order to get along with as few components, you designed the existing air release valve (6) so that it bez the safety function. too high pressure to be able to take over.

Das Belüftungsventil für den Pumpkörper entspricht in der Auslegung in etwa Ventil (7), es säße im Bauschema noch vor der Pumpe und öffnet durch die Druckdifferenz, Normalluftdruck-Unterdruck Pumpkörper, nur in Richtung Pumpe.The venting valve for the pump body corresponds in design around valve (7), it would be in the design scheme before the pump and opens by the pressure difference, normal air pressure vacuum pump body, only in the direction of the pump.

After putting on the helmet, a pump in the right and left chin guard is actuated by pivoting two laterally foldable chin brackets (12) (13), since the two pump pistons (19) sit at the opposite ends of a common, flexible push rod (15).

Bild 5 zeigt die Kinnschutzbügel-Hälften (12) (13), wie sie drehbar an den beiden Scharnieren (11) (14) gelagert sind, den Unterkiefer von unten her umschließen und damit einen Kinnriemen ersetzen. Auch der kinnunter­greifende Teil kann durch den Luftpolstersack gebildet werden.Figure 5 shows the chin guard halves (12) (13), as they are rotatably mounted on the two hinges (11) (14), enclose the lower jaw from below and thus replace a chin strap. The Chinuntergreifende part can be formed by the air cushion bag.

§ 2.2 NÄHERE BESCHREIBUNG§ 2.2 DETAILED DESCRIPTION

Der herkömmlich einteilige Kinnschutzbügel eines Motor­rad-Vollvisierhelms wird symmetrisch in eine rechte und linke Hälfte geteilt und jede Hälfte (12 (13)) mittels Scharnier (11) (14) seitlich schwenkbar am Helm befestigt. Zum Helmauf- und absetzen werden die beiden Bügelhälften seitlich weggeklappt; nach dem Aufsetzen werden sie zu­einander hin geschwenkt und dort verriegelt.The conventional one-piece chin guard of a full-face motorcycle helmet is split symmetrically into right and left halves, and each half (12 (13)) is laterally pivotally attached to the helmet by hinge (11) (14). To put the helmet on and off the two bracket halves are folded away sideways; After putting them are pivoted toward each other and locked there.

Bild 7 zeigt einen Längsschnitt durch die Seitenflanke des rechten Kinnbügels (13) mit Pumpe, ohne Kinnunter­fassung.Figure 7 shows a longitudinal section through the side flank of the right chin guard (13) with pump, without chin support.

Entlang der Kinnschutzflanken ist an der Innenseite je ein Kunststoffhohlkörper (18) verlegt, dessen Ende zum Helm hin über einen Gewindestopfen (21) in die Schlauch­leitung (22) zum Luftpolstersack mündet. Von der anderen Stirnseite des Hohlkörpers her, wird durch das Zusammen­ klappen der beiden Kinnschutzbügel, je ein Kolben (19), im Hohlkörper, in Richtung Helm bewegt, wodurch Luft aus dem Hohlkörper in den Luftsack (3) gelangt.
Da der Kolben eine leichte Kurvenbahn beschreibt, darf das Kolbenhemd nur eine kleine Anlegefläche besitzen, außerdem muß der Kolben eine Kipp-Spiel zur Schubstangen- (15) - längsachse aufweisen. Die Pump-Kolben sitzen jeweils an einem Ende nur eines gemeinsamen Pleuels (15), sodaß die Kolben beim Zusammen­klappen der beiden Kinnschutzhälften eine Relativ-­Bewegung zum sie umgebenden Hohlkörper erfahren. Das Pleuel besteht aus einem genügend knickfesten Glasfaser / Kunststoff-Stab.
In dieser einfachen Variante wird der Luftsack nur durch Schließen bzw. Öffnen der Kinnbügel aufgepumpt bzw. ent­lüftet. Die individuelle Einstellung des gepumpten Luft­volumens kann über eine Längenänderung des Glasfiber-­Pleuels geschehen. Bei der Ausführung ohne Ventile werden zur Verminderung der Leckrate des Systems, die beiden vorderen Stopfen (17) der Pumpkörper, bei geschlossenen Kinnbügeln, durch eine Weichdichtung (16) an ihrer gemein­samen Stoßfläche nach außen abgedichtet.
Die Entlüftung des Pumphohlkörpers beim Öffnen des Helms geschieht über die Schubstangen-Bohrung des vorderen Gewindestopfens (17), die bei entriegelten Kinnbügeln nicht mehr abgedichtet ist.
Die Pumpkörper liegen eingebettet zwischen Helmaußen­schale (1) und der Unterkieferinnenpolsterung (20); sie können im Querschnitt kreisförmig sein; zur Erzielung besserer Raumnutzung, und damit höherer Pumpvolumina, empfiehlt sich jedoch ein längliches Rechteck-Profil.Along the chin guard flanks a plastic hollow body (18) is laid on the inside, the end of the helmet towards a helical plug (21) opens into the hose line (22) for air cushion bag. From the other end of the hollow body ago, is through the together flaps of the two chin guard, each a piston (19), in the hollow body, moves in the direction of the helmet, whereby air from the hollow body into the air bag (3) passes.
Since the piston describes a slight curved path, the piston skirt must have only a small contact surface, also the piston must have a tilting play to the push rod (15) - longitudinal axis. The pump pistons each sit at one end only a common connecting rod (15), so that the pistons experience a relative movement to the surrounding hollow body when folding the two chin guard halves. The connecting rod consists of a sufficiently kink-resistant glass fiber / plastic rod.
In this simple variant, the airbag is inflated or vented only by closing or opening the chin guard. The individual adjustment of the volume of air pumped can be done via a change in length of the glass fiber connecting rod. In the version without valves to reduce the leakage rate of the system, the two front plugs (17) of the pump body, with closed chin straps, sealed by a soft seal (16) at its common abutment surface to the outside.
The ventilation of the pump hollow body when opening the helmet is done via the push rod hole of the front threaded plug (17), which is no longer sealed with unlocked chin straps.
The pump body are embedded between the helmet outer shell (1) and the lower jaw padding (20); they may be circular in cross section; However, to achieve better space utilization, and thus higher pumping volumes, an elongated rectangular profile is recommended.

Es können zusätzlich ein Druckfeineinstellungs-Ventil (6) und ein Ein-Wege-Sperr-Ventil (7) zwischen Pumpe und Luftpolstersack verbaut werden.In addition, a pressure fine adjustment valve (6) and a one-way shut-off valve (7) can be installed between the pump and the air bag.

Bild 2 erklärt das Bauschema mit Regulier-Ventil (6) und Sperr-Ventil (7).Figure 2 explains the construction scheme with regulating valve (6) and blocking valve (7).

§ 3 MOTORRADHELM MIT KLIMATISIERENDEM STAUDRUCK­LUFTPOLSTER NACH PATENTANSPRUCH NR. 4; NOCH EIN ANWENDUNGSBEISPIEL§ 3 MOTORCYCLE HELMET WITH AIR-CONDITIONING AIR-PUSH PADDLE ACCORDING TO PATENT CLAIM NO. 4; STILL AN APPLICATION EXAMPLE § 3.1 KURZBESCHREIBUNG§ 3.1 SHORT DESCRIPTION

Statt eines einfachen, rundum befestigten, Textilinnen­futters im herkömmlich aufgebauten Motorrad-Helm, besitzt die Erfindung eine Textillage (24), die nur lose mit der darunterliegenden Stoßdämpferschicht (2) verbunden ist. Im Stirn- und Backenbereich, an der Vorderseite des Helms, fließt, durch den Fahrtwind, über einen Eintrittsstutzen (23) Luft zwischen Textilschicht und der Stoßdämpfer­schicht, die an der Helmrückseite abgeleitet wird; so bildet sich ein dynamisches Luftpolster.
Die Textillage soll geringfügig luft- und wasserdampf­durchlässig sein; dadurch wird eine Luft- und Verdunst­ungskühlung unter dem Helm wirksam.Instead of a simple, all-round, textile lining in the conventionally constructed motorcycle helmet, the invention has a textile layer (24), which is only loosely connected to the underlying shock absorber layer (2). In the front and back area, at the front of the helmet, flows through the airstream, via an inlet nozzle (23) air between the textile layer and the shock absorber layer, which is derived at the back of the helmet; This creates a dynamic air cushion.
The textile layer should be slightly air and water vapor permeable; This makes air and evaporative cooling under the helmet effective.

§ 3.2 NÄHERE BESCHREIBUNG§ 3.2 DETAILED DESCRIPTION

Ist die Lufteintrittsöffnung (23) entsprechend groß gegenüber der Luftaustrittsöffnung (25), hebt sich der Helm, bei genügend schneller Fahrt, durch den Staudruck des Fahrtwinds vom Kopf ab, sodaß auch hier ein Luft­polster-Effekt zum Tragen kommt. Die einströmende Luft wird über, im Querschnitt regelbare, Einlaßschlitze (23) geführt und, über Kanäle oder frei fließend, unter der dünnen Textilschicht (24) die einen Klimaaustausch ermöglicht, zur Helmhinterseite geleitet und gelangt von dort unter dem Helm vor (25).
Die Textilschicht (24) wird am vorteilhaftesten aus einem Verbund von dünner Baumwolle oder Seide, kopfseitig,
- zur Abführung des Schweißes -, bestehen und einer direkt darüberliegenden, feinst perforierten, dünnen Kunststoffolie, deren Poren, sich verjüngend, in Fluß­richtung des Luftstroms zeigen.
Auch GORETEX (eingetragenes Warenzeichen), in ent­sprechend durchlässiger Ausführung, kann als Textil­lage verwendet werden.If the air inlet opening (23) is correspondingly large in relation to the air outlet opening (25), the helmet, with sufficiently fast travel, lifts itself away from the head due to the back pressure of the airstream, so that an air cushion effect also comes into effect here. The incoming air is passed over, in cross-section controllable, inlet slots (23) and, via channels or free-flowing, under the thin textile layer (24) which allows a climate change, directed to the helmet backside and passes from there under the helmet (25).
The textile layer (24) is most advantageously made of a composite of thin cotton or silk, on the head side,
- To dissipate the sweat -, and an overlying, finely perforated, thin plastic film whose pores, tapering, in the flow direction of the air flow show.
Also GORETEX (registered trademark), in accordance with permeable design, can be used as a textile layer.

Bild 6 zeigt das Prinzip des fließenden, klimatisieren­den Luftpolsters mit Luft-Eintrittschlitzen (23), porösem Textilfutter (24), Luft-Austrittsöffnung (25) und der Flußrichtung des Luftstroms.Figure 6 shows the principle of the flowing, air-conditioning air cushion with air inlet slots (23), porous textile lining (24), air outlet opening (25) and the flow direction of the air flow.
