Abstract

The helmet has an inner helmet shell (2), and an outer helmet shell (1) with air guiding edges (3a, 3b), which extend based on a front side via an eye region of a carrier directly at or in small distance over an upper edge (5) of a view opening at an upper surface of the outer shell in a flow direction. The air guiding edges end at a rear lower region of the helmet, at a neck closure (6) or at small distance that is equal to distance of a front helmet region. The air guiding edges are designed as groove or dome-shape with a specific depth and/or height and with a specific width. An independent claim is also included for a single or multi-part outer shell for a sports helmet, comprising air guiding edges.

Description

Die Erfindung betrifft einen Sporthelm mit geringem Luftwiderstand.The invention relates to a sports helmet with low air resistance.

Bei verschiedensten Sportarten, z.B. beim Radsport oder beim Skiabfahrtslauf, ist es angebracht, einen Helm zu tragen bzw. sind diese vorgeschrieben. Insbesondere im Wettkampfbereich und im Hochleistungssport spielt dabei der Luftwiderstand der Helme, neben anderen wichtigen Eigenschaften wie z.B. der Schlagabsorptionsfähigkeit oder dem Gewicht, eine große Rolle. Je nach Anwendungsgebiet sind verschiedene Helmformen bekannt. Alle Formen weisen im Stirnbereich eine Sichtöffnung auf. Insbesondere bei Radfahrern kommen Helme zum Einsatz, welche nur den oberen Kopfbereich überdecken und die Ohren frei bleiben. Bei Ski- und Snowboardfahrern finden Helme Anwendung, welch zusätzlich die Ohren überdecken. Diese Helme schließen im Vergleich zu oben genannten Fahrradhelmen tiefer im Nackenbereich ab. Weiterhin bekannt sind Integralhelme, welche den gesamten Kopf des Trägers inklusive des Kinnbereiches umschließen.In a variety of sports, e.g. when cycling or ski downhill, it is appropriate to wear a helmet or these are prescribed. In particular, in the field of competition and in high-performance sports, the air resistance of the helmets, among other important properties such. the impact absorbency or weight, a big role. Depending on the field of application, different types of helmets are known. All forms have a viewing opening in the forehead area. Especially for cyclists helmets are used, which cover only the upper head area and the ears remain free. For skiers and snowboarders helmets are used, which additionally cover the ears. These helmets close in comparison to the above-mentioned bicycle helmets deeper in the neck area. Also known are integral helmets, which enclose the entire head of the wearer, including the chin area.

Im Sport- und Freizeitbereich werden Helme eingesetzt, die eine harte, schlagabweisende Außenschale aufweisen, die mit einer dämpfenden, energievernichtenden Innenschale, verbunden ist. Das Material der schlagresistenten, jedoch elastischen Außenschale ist im allgemeinen mit Kevlar-, Glas- oder Carbonfasern verstärkter Kunststoff. Die Außenschale kann dabei ein- oder mehrteilig gefertigt sein. Die Innenschale besteht aus Hartschaum z. B. aus expandiertem Polystyrol, oder einem vergleichbaren Leichtbauwerkstoff. Die Verbindung von Außen- und Innenschale kann form-, kraft- oder stoffschlüssig erfolgen.In the sports and leisure sector helmets are used, which have a hard, shock-resistant outer shell, which is connected to a damping, energy-dissipating inner shell. The material of the impact-resistant, but elastic outer shell is generally reinforced with Kevlar, glass or carbon fiber reinforced plastic. The outer shell can be made one or more parts. The inner shell is made of hard foam z. B. of expanded polystyrene, or a comparable lightweight material. The connection of outer and inner shell can be positive, positive or cohesive.

Die DD 253 759 A1 beschreibt einen Helm mit einer Abrisskante im hinteren oberen Bereich der Helmkalotte. Diese Abrisskante reduziert dabei vor allem die Auftriebskräfte des Helmes, und damit die durch den Kinngurt übertragenen Kräfte auf den Halsbereich des Trägers.The DD 253 759 A1 describes a helmet with a tear-off edge in the rear upper area of the helmet shell. This spoiler edge reduces primarily the buoyancy forces of the helmet, and thus the forces transmitted through the chin strap forces on the neck area of the wearer.

In der DE 33 20 301 C1 wird ein Sturzhelm vorgestellt, der auf der Oberfläche eine Vielzahl von Luftverwirbelungen erzeugenden Unebenheiten aufweist. Dadurch wird der Luftwiderstand bei hohen Strömungsgeschwindigkeiten reduziert. Bei geringen Strömungsgeschwindigkeiten bewirken die Unebenheiten jedoch eine Erhöhung des Luftwiderstandes.In the DE 33 20 301 C1 is presented a crash helmet, which has on the surface a variety of air turbulence generating bumps. As a result, the air resistance is reduced at high flow velocities. At low flow velocities, however, the bumps cause an increase in air resistance.

In der DE 20 21 5102 U1 wird ein Helm für Zweiradfahrer offenbart, der zur Reduktion des Luftwiderstandes vorspringende Rippen aufweist, welche von der Vorderseite des Helmes annähernd auf die Mitte der Rückseite der Helmkalotte zulaufen. Die Zusammenführung der Rippen im hinteren Bereich des Helmes ähnelt dabei einer Abrisskante.In the DE 20 21 5102 U1 a helmet for cyclists is disclosed, which has the reduction of air resistance projecting ribs, which run from the front of the helmet approximately to the center of the back of the helmet shell. The merging of the ribs in the rear of the helmet resembles a spoiler lip.

WO 01/52676 A1 beschreibt einen Sporthelm mit einer äußeren und einer inneren Helmschale, und einem Luftleitkanal, der sich ausgehend von der Stirnseite zwischen der äußeren und der inneren Schale in Strömungsrichtung erstreckt. WO 01/52676 A1 describes a sports helmet with an outer and an inner helmet shell, and an air duct, which extends from the end face between the outer and the inner shell in the flow direction.

Die Aufgabe der vorliegenden Erfindung besteht darin, einen Sporthelm vorzuschlagen, der einen besonders geringen Luftwiderstand aufweist.The object of the present invention is to propose a sports helmet, which has a particularly low air resistance.

Erfindungsgemäß wird die Aufgabe durch einen Sporthelm mit den im Anspruch 1 genannten Merkmalen gelöst. Vorteilhafte Varianten des Sporthelmes sind Gegenstand von Unteransprüchen.According to the invention the object is achieved by a sports helmet with the features mentioned in claim 1. Advantageous variants of the sports helmet are the subject of dependent claims.

Der erfindungsgemäße Sporthelm weist an der äußeren Helmschale mindestens eine Luftleitkante auf, die sich ausgehend von der Stirnseite des Helmes - direkt an oder in geringer Entfernung über der oberen Kante der Sichtöffnung des Helmes - über die Oberfläche der äußeren Helmschale in Strömungsrichtung (bei gerader Anströmung von vom) erstreckt, und im hinteren unteren Bereich des Helmes, im Nackenabschluss oder in geringer Entfernung darüber, mit annähernd gleichem Abstand zueinander wie im vorderen Helmbereich, endet. Bei einem Helm mit nur einer Luftleitkante ist diese mittig auf der äußeren Helmschale platziert. Bei Helmen mit mehreren Luftleitkanten sind diese symmetrisch angeordnet.The sports helmet according to the invention has on the outer helmet shell at least one air guide edge, starting from the front of the helmet - directly at or a short distance above the upper edge of the viewing port of the helmet - over the surface of the outer helmet shell in the flow direction (in a straight flow of from) and ends at the rear lower portion of the helmet, at the neck finish or at a short distance above it, at approximately the same distance from each other as in the front helmet area. In a helmet with only one airfoil this is placed centrally on the outer helmet shell. For helmets with several air guide edges, these are arranged symmetrically.

Vorteilhaft sind zwei Luftleitkanten auf der äußeren Schale angeordnet, die im Stirnbereich des Helmes, über dem Augenbereich des Trägers ansetzen.Advantageously, two air guide edges are arranged on the outer shell, which attach in the front area of the helmet, over the eye area of the wearer.

Die Luftleitkante/ Luftleitkanten können als Nut (Vertiefung) oder als Auswölbung der äußeren Helmschale ausgebildet sein. Für die Nuten bzw. Auswölbungen sind verschiedene Querschnittsgeometrien möglich, beispielhaft werden runde, ellipsenförmige oder viereckige Querschnitte genannt.The air guide edge / air guide edges may be formed as a groove (recess) or as a bulge of the outer helmet shell. For the grooves or bulges different cross-sectional geometries are possible, for example, round, elliptical or quadrangular cross-sections are called.

Bei mehrteiligen, insbesondere dreiteiligen, äußeren Helmschalen können die einzelnen Teile so dimensioniert werden, dass sich deren Nahtbereich mit der Luftleitkante deckt. Ein nach oben auskragender Keder aus Gummi oder einem ähnlichen Material zwischen den aufeinandertreffenden Teilen der äußeren Schale fixiert deren die Position und bildet gleichzeitig durch den auskragenden oberen Teil eine Luftleitkante. Eine andere Möglichkeit besteht darin, die Teile der äußeren Helmschale überlappen zu lassen und die Überlappung als Luftleitkante auszubilden. Die sickenartigen Luftleitkanten wirken dabei zugleich als Versteifung und erhöhen die Biege- und Torsionssteifigkeit der Helmschale.In the case of multi-part, in particular three-part, outer helmet shells, the individual parts can be dimensioned such that their seam area coincides with the air-guiding edge. An upwardly projecting piping made of rubber or a similar material between the colliding parts of the outer shell fixed their position and forms at the same time by the projecting upper part of an air guide. Another possibility is to overlap the parts of the outer helmet shell and to form the overlap as the air guide. At the same time, the bead-like air-guiding edges act as a stiffener and increase the bending and torsional rigidity of the helmet shell.

Die Luftleitkanten sind bei allen Helmtypen mit einer glatten, geschlossenen, ellipsoidähnlichen äußeren Helmschale ohne Abrisskante anwendbar.The air guide edges are applicable to all types of helmets with a smooth, closed, ellipsoid-like outer helmet shell without trailing edge.

Die Auswölbungen bzw. die Nuten haben eine Tiefe bzw. Höhe zwischen 2 mm und 8 mm und eine Breite zwischen 2 mm und 14 mm. Vorteilhaft sind Tiefen bzw. Höhen im Bereich zwischen 3 mm und 5 mm und eine Breiten zwischen 5 mm und 10 mm.The bulges or grooves have a depth or height between 2 mm and 8 mm and a width between 2 mm and 14 mm. Advantageously, depths or heights in the range between 3 mm and 5 mm and a width between 5 mm and 10 mm.

Überraschenderweise zeigte sich bei Versuchen im Windkanal, dass Sporthelme mit den erfindungsgemäßen Luftleitkanten einen deutlich verminderten cw- Wert aufwiesen. So erreichte ein Helm mit einer Auswölbung mit halbkreisförmigen Querschnitt mit einer Höhe von 5 mm als Luftleitkante einen Wert von cw=0,19-0,21 bei einem Anströmwinkel α=43°. Demgegenüber wiesen Helme ohne die erfindungsgemäßen Luftleitkanten einen Wert von cw=0,26-0,31 auf.Surprisingly, tests in the wind tunnel showed that sports helmets with the inventive air guiding edges had a markedly reduced c w value. Thus, a helmet with a bulge having a semicircular cross section with a height of 5 mm as the air guide edge reached a value of c w = 0.19-0.21 at an angle of incidence α = 43 °. In contrast, helmets without the inventive air guide edges had a value of c w = 0.26-0.31.

Nachfolgend werden zwei bevorzugte Ausführungsformen anhand von Figuren erläutert. Dabei zeigen:
