Abstract
(A1) Es wird eine Fahrzeugscheibe (1) angegeben, die einen Polarisationsfilter (2) umfasst, der derart orientiert ist, dass er unter einem Winkel ? zwischen einschliesslich 50° und einschliesslich 70° zur Normalen (6) der Fahrzeugscheibe (1) ein Transmissionsminimum fuer s-polarisiertes Licht aufweist. Auf diese Weise wird Verminderung der Reflexion der Fahrzeugscheibe (1) fuer aus dem Fahrzeuginneren auftreffendes Licht erzielt.
DE 102009052354 A1 UPAB: 20110524 NOVELTY - The pane (1) has a polarization filter (2) oriented such that the filter exhibits minimum transmission for s-polarized light below an angle of incidence (alpha) to a normal (6) of the pane, where the angle lies in a range between 50 degree and 70 degree. The polarization filter is arranged on an inner side (11) of the pane that is made of tempered safety glass or composite safety glass. An inner pane and an outer window pane are connected by a connecting film, where a reflection-reducing coating is applied on an inner side of the inner pane. USE - Pane e.g. front pane and rear pane, for a vehicle such as motor vehicle i.e. passenger car (all claimed). Can also be used for a land vehicle i.e. rail vehicle, a water vehicle i.e. ship and an air vehicle i.e. aircraft. ADVANTAGE - The polarization filter is oriented such that the filter exhibits the minimum transmission for s-polarized light below the angle of incidence to the normal of the pane, where the angle lies in the range between 50 degree and 70 degree, thus ensuring decreased light reflection in the pane. The pane is made of tempered safety glass or composite safety glass, thus avoiding breaking of the pane into small pieces in case of destruction caused by pre-loading, and hence avoiding danger of injury to a driver.
