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.e. Helmets, in which in the helmet a chin guard is integrated, usually have a smooth outer Dome surface. But you have already tried the aerodynamic Properties of such a helmet by structuring the dome surface to improve. For example, the surface is known with a variety of troughs forming a golf ball-like To provide surface structure. Helmets are also known which have spoiler-like projections on the back.

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.Proceeding from this, the invention is based on the object Helmet of the type in question to improve so that the aerodynamic Properties are optimized and at the same time an appealing 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 the helmet has protruding ribs that extend from the area of the Front of the helmet approximates the center of the back of the helmet run.

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 embodiment according to the invention performs like measurements in the wind tunnel show a significant improvement in aerodynamic properties, especially at higher driving speeds. Mirror at the same time these improved usage properties also in the external appearance again, which is a particularly dynamic impression taught.

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 apex the ribs have a smooth transition to the body of the Have helmet cap, so that turbulence, which leads to an increase in the Air resistance could be avoided in the area of the rib apex become.

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.A rib advantageously extends from the top edge in each case and the lower edge of the visor to the rear. This will make the Limiting edges of the visor optically recorded and continued, see above 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, one can merge at the top of the helmet cap by two Ridges delimited, almost triangular elevation be formed with its rear end starting from a triangular tip over a rib along the apex center line into the middle area the back of the helmet merges.

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 can be from the rear lower edge of the helmet cap starting with an approximately triangular elevation stretch away, starting from a triangular tip along a Rib centerline of apex in the middle of the back of the helmet transforms.
