Description

Die Erfindung richtet sich auf einen Schutzhelm für Zweiradfahrer, insbesondere einen Integral-Motorradhelm mit einer eine Oberflächenstruktur aufweisenden Helmkalotte, die eine durch ein Visier abgedeckte Sichtöffnung aufweist.The invention is directed to a protective helmet for cyclists, in particular an integral motorcycle helmet with a surface having a helmet cap having a covered by a visor viewing opening.

Integralhelme für Motorradfahrer, d.h. Helme, bei welchen in die Helmkalotte ein Kinnschutz integriert ist, weisen üblicherweise eine glatte äußere Kalottenoberfläche auf. Man hat aber auch schon versucht, die aerodynamischen Eigenschaften eines solchen Helms durch Strukturierung der Kalottenoberfläche zu verbessern. So ist es beispielsweise bekannt, die Oberfläche mit einer Vielzahl von Mulden unter Ausbildung einer golfballartigen Oberflächenstruktur zu versehen. Weiterhin sind Helmkalotten bekannt, die an der Rückseite spoilerartige Vorsprünge aufweisen.Full face helmets for motorcyclists, i. Helmets in which a chin guard is integrated in the helmet shell usually have a smooth outer dome surface. However, it has also been tried to improve the aerodynamic properties of such a helmet by structuring the Kalottenoberfläche. For example, it is known to provide the surface with a plurality of troughs to form a golf ball-like surface structure. Furthermore, helmets are known which have spoiler-like projections on the back.

DE 201 01 053 U beschreibt einen Motorradhelm, mit einer eine Oberflächenstruktur aufweisenden Helmkalotte, die eine durch ein Visier abgedeckte Sichtöffnung aufweist, wobei die Außenseite der Helmkalotte vorspringende Rippen aufweist, die sich bogenförmig im Hinterkopfbereich der äußeren Helmkalotte erstrecken, und wobei die Rippen als separate Teile ausgebildet sind und an der Helmkalotte über einen begrenzten Bereich individuell positionierbar gelagert sind. DE 201 01 053 U describes a motorcycle helmet, having a surface having a helmet cap having a covered by a visor viewing opening, wherein the outside of the helmet shell has projecting ribs which extend arcuately in the occipital region of the outer helmet shell, and wherein the ribs are formed as separate parts and to the helmet calotte are stored individually positioned over a limited area.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, einen Schutzhelm der in Betracht stehenden Art so zu verbessern, dass die aerodynamischen Eigenschaften optimiert werden und gleichzeitig ein ansprechendes Erscheinungsbild geschaffen wird.On this basis, the present invention seeks to improve a protective helmet of the type in question so that the aerodynamic properties are optimized and at the same time an attractive appearance is created.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Außenseite der Helmkalotte vorspringende Rippen aufweist, die von dem Bereich der Vorderseite des Helms annähernd auf die Mitte der Rückseite der Helmkalotte zulaufen.This object is achieved in that the outside of the helmet shell has projecting ribs, which run from the region of the front of the helmet approximately to the center of the back of the helmet shell.

Die erfindungsgemäße Ausgestaltung führt, wie Messungen im Windkanal zeigen, zu einer deutlichen Verbesserung der aerodynamischen Eigenschaften, insbesondere bei höheren Fahrgeschwindigkeiten. Gleichzeitig spiegeln sich diese verbesserten Nutzungseigenschaften auch im äußeren Erscheinungsbild wieder, welches einen besonders dynamischen Eindruck vermittelt.The design according to the invention, as measurements in the wind tunnel show, leads to a significant improvement in the aerodynamic properties, in particular at higher driving speeds. Mirror at the same time These improved usage properties are also reflected in the external appearance, which gives a particularly dynamic impression.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Scheitel der Rippen einen sanft verlaufenden Übergang zum Grundkörper der Helmkalotte aufweisen, so dass Verwirbelungen, die zu einer Erhöhung des Luftwiderstandes führen könnten, im Bereich der Rippen-Scheitel vermieden werden.In a further embodiment of the invention, it is provided that the vertexes of the ribs have a smooth transition to the main body of the helmet shell, so that turbulence, which could lead to an increase in air resistance, are avoided in the region of the rib apex.

Günstigerweise erstreckt sich jeweils eine Rippe ausgehend von der Oberkante und der Unterkante des Visiers nach hinten. Hierdurch werden die Begrenzungskanten des Visiers optisch aufgenommen und fortgesetzt, so dass eine harmonische Ausgestaltung erreicht wird.Conveniently, in each case extends a rib, starting from the upper edge and the lower edge of the visor to the rear. As a result, the boundary edges of the visor are optically recorded and continued, so that a harmonious design is achieved.

Mit Vorteil kann an der Oberseite der Helmkalotte eine durch zwei zusammenlaufende Rippen begrenzte, annähernd dreieckförmige Erhebung ausgebildet sein, die mit ihrem hinteren Ende ausgehend von einer Dreieckspitze über eine Rippe längs der Scheitelmittellinie in den Mittelbereich der Helmrückseite übergeht.Advantageously, at the top of the helmet cap a limited by two converging ribs, approximately triangular elevation may be formed, which merges with its rear end, starting from a triangle tip over a rib along the apex center line in the central region of the helmet back.

Korrespondierend hierzu kann sich von der hinteren Unterkante der Helmkalotte ausgehend eine annähernd dreieckförmige Erhebung nach oben wegerstrecken, die ausgehend von einer Dreieckspitze über eine längs der Scheitelmittellinie verlaufende Rippe in den Mittelbereich der Helmrückseite übergeht.Corresponding to this, starting from the rear lower edge of the helmet calotte, an approximately triangular elevation can extend upwards, which, starting from a triangle tip, merges into the middle region of the helmet backside via a rib extending along the vertex centerline.
