Abstract
Official abstract text for this publication.
A vehicle window includes a window body assembly having at least one window body, the window body assembly having an outer side facing the vehicle environment and an inner side facing the vehicle interior and a light-conducting layer forming the inner side; an illuminating device configured to couple light into the light-conducting layer; and a light-decoupling device configured to decouple light from the light-conducting layer in the direction of the vehicle interior. The light-decoupling device includes transparent structural elements made of a polymer material and molded or connected to the inner side of the window body assembly by extrusion or foaming or injection molding or gluing.
First claim
Opening claim text (preview).
1 . A vehicle window comprising: a window body assembly having at least one window body, the window body assembly having an outer side facing the vehicle environment and an inner side facing the vehicle interior and a light-conducting layer forming the inner side; an illuminating device configured to couple light into the light-conducting layer; and a light-decoupling device configured to decouple light from the light-conducting layer in the direction of the vehicle interior, characterized in that the light-decoupling device comprises transparent structural elements made of a polymer material and molded or connected to the inner side of the window body assembly by extrusion or foaming or injection molding or gluing. 2 . The vehicle window according to claim 1 , wherein the polymer material comprises a polyurethane material. 3 . The vehicle window according to claim 1 , wherein the structural elements comprise rib. 4 . The vehicle window according to claim 3 , wherein the ribs are parallel to each other. 5 . The vehicle window according to claim 3 , wherein adjacent ribs have a distance of no more than 40 mm from each other. 6 . The vehicle window according to claim 3 , wherein the ribs each have a height of at least 2 mm and in particular at least 3.9 mm from the inner side of the window body assembly. 7 . The vehicle window according to claim 3 , wherein the ribs each have a width of at least 6 mm and in particular at least 6.9 mm. 8 . The vehicle window according to claim 1 , further comprising a light-coupling device which couples light of the illuminating device into the light-conducting layer via the inner side of the window body assembly. 9 . The vehicle window according to claim 1 , wherein the window body assembly comprises an outer window body and an inner window body, the inner window body forming the light-conducting layer and being connected to the outer window body via at least one connecting layer. 10 . The vehicle window according to claim 9 , wherein an electrically switchable shading device is disposed between the outer window body and the inner window body.
