Stand der TechnikState of the art

Visiere finden Verwendung insbes. in Helmen für Motorradfahrer und sonstigen Schutzhelmen.Visors are used especially in helmets for motorcyclists and other protective helmets.

Es gibt klar-transparente und getönte Visiere.There are clear-transparent and tinted visors.

Problemproblem

Bei wechselnden Lichtverhältnissen aufgrund der Wetterlage oder der Fahrtstrecke (z.B. Tunnel) ist es aufwendig oder unmöglich, das transparente gegen ein getöntes Visier und vice versa auszutauschen. Auch die Kombination aus transparentem Visier mit / ohne Sonnenbrille ist nur aufwendig, insbes. während der Fahrt an wechselnde Lichtverhältnisse anpassbar; für Brillenträger besteht das Sonderproblem, dass eine Sonnenbrille als teure Sehkorrektur-Brille erforderlich ist.When the light conditions change due to the weather or the route (e.g. tunnels), it is difficult or impossible to exchange the transparent visor for a tinted one and vice versa. The combination of a transparent visor with/without sunglasses is also difficult to adapt to changing light conditions, especially while driving; for those who wear glasses, there is the special problem that sunglasses are required as expensive vision correction glasses.

Beispiel und HauptanwendungsbereichExample and main application area

Das Visier insbes. für Motorradhelme wird so ausgeführt, dass es in Abhängigkeit von der Intensität der Sonneneinstrahlung seine Tönung automatisch verändert.The visor, especially for motorcycle helmets, is designed in such a way that it automatically changes its tint depending on the intensity of the sunlight.

LösungSolution

Phototrope Kunststoffe beinhalten lichtempfindliche Moleküle, die sich mit der Intensität der UV-Strahlung verändern, d.h. Licht mehr oder weniger absorbieren. Sie finden bislang vor allem Verwendung als optische Brillengläser. Zwei grundsätzliche Lösungen sind zu unterscheiden:Phototropic plastics contain light-sensitive molecules that change with the intensity of UV radiation, i.e. absorb light more or less. To date, they have been used primarily as optical lenses. There are two basic solutions:

1. das Visier wird aus dem Material eines phototropen Kunststoffs hergestellt1. the visor is made of photochromic plastic

2. auf dem Visier wird eine phototrope Kunststofffolie aufgebracht.2. A phototropic plastic film is applied to the visor.

erreichte Vorteileachieved benefits

Das Visier passt sich automatisch wechselnden Lichtverhältnissen an. Das Wechseln des Visiers zwischen klar-transparent und getönt entfallt, ebenso das Mitführen bzw. Wechseln einer Sonnenbrille. Der Nutzungskomfort des Helmes erhöht sich, Anschafrüngskosten reduzieren sich, da auf ein 2. (getöntes) Visier und gfls. auf eine Sonnenbrille verzichtet werden kann. Die Verkehrssicherheit erhöht sich, da jederzeit ein optimaler Tönungsgrad und optimale Sichtverhältnisse gegeben sind.The visor automatically adapts to changing light conditions. There is no need to change the visor between clear-transparent and tinted, nor is there a need to carry or change sunglasses. The helmet is more comfortable to use, and purchase costs are reduced because a second (tinted) visor and possibly sunglasses are no longer required. Road safety is increased because the optimum level of tint and visibility are always available.
