Abstract
Bei einem Visier, insbesondere für einen Motorradhelm oder dergleichen, umfassend wenigstens eine transparente Sichtscheibe, ist vorgesehen, dass die Sichtscheibe (2) mit einer Polarisationsfolie (7) verbunden ist.In the case of a visor, in particular for a motorcycle helmet or the like, comprising at least one transparent lens, it is provided that the lens (2) is connected to a polarizing film (7).
Description
Die Erfindung richtet sich auf ein Visier, insbesondere für Motorradhelme, umfassend wenigstens eine transparente Sichtscheibe.The Invention is directed to a visor, in particular for motorcycle helmets, comprising at least one transparent viewing window.
Derartige Visiere an Motorradhelmen, Skihelmen oder Arbeitsschutzhelmen müssen einerseits die Augen des Benutzers wirksam vor Fahrtwind und Partikeln schützen, andererseits aber dem Benutzer eine möglichst uneingeschränkte und ungetrübte Sicht ermöglichen.such Visors on motorcycle helmets, ski helmets or safety helmets must on the one hand the Protect the eyes of the user effectively against wind and particles, on the other hand but the user one as possible unlimited and clear view enable.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein derartiges Visier so auszugestalten, dass insbesondere Blendungen vermieden werden.Of these, Based on the object of the invention, such a Visor in such a way that in particular glare can be avoided.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Sichtscheibe mit einer Polarisationsfolie verbunden ist.These Task is inventively characterized solved, that the viewing window is connected to a polarizing film.
Aufgrund der Polarisationswirkung wird eine Blendung, z. B. durch das auf nassen Straßen reflektierte und dementsprechend polarisierte Licht, wirksam vermieden und der Benutzer hat den Eindruck natürlicher Farben mit natürlichem Kontrast.by virtue of the polarization effect is a glare, z. B. by the on wet roads reflected and accordingly polarized light, effectively avoided and the user has the impression of natural colors with natural Contrast.
Die Polarisationswirkung muss so ausgelegt sein, dass die Transmission zur uneingeschränkten Verwendung des Visiers bei 80 bis 100% liegt, bei einer auf den Tag beschränkten Benutzung bei 50 bis 80%. Vorzugsweise ist vorgesehen, dass die Polarisationsfolie als plattenförmiges Material ausgebildet bzw. mit einem plattenartigen Trägermaterial verbunden ist.The Polarization effect must be designed so that the transmission for unrestricted use of the visor at 80 to 100%, in a limited to the day use at 50 to 80%. It is preferably provided that the polarization film as a plate-shaped Material formed or with a plate-like carrier material connected is.
Die Sichtscheibe kann ebenfalls aus einem plattenartigen Material bestehen und zusammen mit der Polarisationsfolie gewölbt in einem Rahmen festgelegt sein, d. h. die Wölbung wird durch den Rahmen vorgegeben und festgelegt.The Lens can also consist of a plate-like material and fixed together with the polarizing film arched in a frame be, d. H. the vault is specified and fixed by the frame.
Günstigerweise ist die Polarisationsfolie zwischen einem äußeren und einem inneren plattenartigen Material angeordnet.conveniently, is the polarizing film between an outer and an inner plate-like Material arranged.
Bei einer ersten Ausführungsform können die innere und die äußere Scheibe aus Acetat bestehen.at a first embodiment can they inner and outer disc made of acetate.
Alternativ kann auch vorgesehen sein, dass die äußere Scheibe aus Polycarbonat und die innere Scheibe aus Acetat bestehen.alternative can also be provided that the outer disc of polycarbonate and the inner disc made of acetate.
Die Acetatscheiben bestehen insbesondere aus Zelluloseacetat, vorzugsweise Zellulosetriacetat.The Acetate discs consist in particular of cellulose acetate, preferably Cellulose triacetate.
Bei einer weiteren bevorzugten Ausführungsform ist vorgesehen, dass die Polarisationsfolie zwischen zwei Acetatscheiben angeordnet ist, welche ihrerseits wieder unter Zwischenschaltung eines Luftpolster mit einer Polycarbonatscheibe verbunden sind.at a further preferred embodiment is provided that the polarizing film between two acetate discs is arranged, which in turn under interposition an air cushion are connected to a polycarbonate disc.
Günstigerweise sind die Acetatscheiben an ihrer jeweiligen Außenseite mit einer Antibeschlag-Beschichtung versehen.conveniently, the acetate discs are on their respective outside with an anti-fog coating Mistake.
Zwischen der Polycarbonatscheibe und den Acetatscheiben ist zur Ausbildung eines isolierenden Luftpolsters eine umlaufende Silikonraupe angeordnet.Between the polycarbonate disc and the acetate discs is for training an insulating silicone bead arranged an insulating air cushion.
Eine weitere Ausführungsform sieht vor, dass die Sichtscheibe aus Polycarbonat besteht und an ihrer Außenseite mit einer Polarisationsfolie versehen ist, die vorzugsweise aufkaschiert ist.A another embodiment provides that the lens is made of polycarbonate and on their outside is provided with a polarizing film which preferably laminates is.
Nachfolgend wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher erläutert. Dabei zeigen:following The invention is based on a preferred embodiment in connection closer to the drawing explained. Showing:
