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).
The invention claimed is: 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, wherein 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 adjacent ribs have a distance of no more than 40 mm from each other. 5. 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. 6. 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. 7. 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. 8. 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. 9. 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, wherein 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, wherein the structural elements comprise rib, and wherein the ribs are parallel to each other.
