Abstract

A vehicle window with a primary window pane arrangement, a secondary window pane that is spaced apart from the primary window pane arrangement and a window funnel that extends between the secondary window pane and the primary window pane arrangement is provided. The vehicle window includes an intermediate space that is formed by the window funnel, the secondary window pane and the primary window pane arrangement, and the intermediate space is sealed and equipped with an air inlet for introducing dehumidified air into the intermediate space. Due to the seal, humid air leading to condensation and frost in the intermediate space is prevented from flowing into the intermediate space during a pressure compensation flow. The passenger comfort is enhanced due to the improved view through the window.

First claim

What is claimed is:

1. A vehicle window, comprising:
a primary window pane arrangement having an outer primary window pane and an inner primary window pane;
a secondary window pane that is spaced apart from the primary window pane arrangement; and
a window funnel that extends between the secondary window pane and the primary window pane arrangement,
wherein an intermediate space formed by the window funnel, the secondary window pane and the primary window pane arrangement is sealed and includes an air inlet for introducing dehumidified air into the intermediate space.

2. The vehicle window of claim 1 , wherein a sealing element is arranged between the window funnel and a boundary surface of the primary window pane arrangement which is directed toward the secondary pane.

3. The vehicle window of claim 1 , in which the primary window pane arrangement further comprises a press-on frame for pressing an inner primary window pane against a window frame and simultaneously forming a hollow space that is connected to a condensation channel for dehumidifying air, and the hollow space and the intermediate space are fluidically connected.

4. The vehicle window of claim 3 , wherein the press-on frame further comprises a bore for producing the fluidic connection between the hollow space and the intermediate space.

5. The vehicle window of claim 1 , wherein the intermediate space is connected to a separate condensation channel that is formed in the vehicle window or on the vehicle window.

6. An aircraft with a fuselage, comprising:
a plurality of vehicle windows that respectively include a primary window pane arrangement having an outer primary window pane and an inner primary window pane, a secondary window pane that is spaced apart from the primary window pane arrangement and a window funnel that extends between the secondary window pane and the primary window pane arrangement,
wherein an intermediate space formed by the window funnel, the secondary window pane and the primary window pane arrangement is sealed and includes an air inlet for introducing dehumidified air into the intermediate space.

7. The aircraft of claim 6 , wherein the air inlet is connected to an air source of an air-conditioning system.

8. The aircraft of claim 6 , wherein the air inlet is connected to an air dehumidifying device.

9. The aircraft of claim 7 , wherein the primary window pane arrangement comprises a press-on frame for pressing an inner primary window pane against a window frame and simultaneously forming a hollow space, and the hollow space and the intermediate space are fluidically connected.

10. A vehicle window, comprising:
a primary window pane arrangement having an outer primary window pane and an inner primary window pane, including a press-on frame for pressing the inner primary window pane against a window frame and simultaneously forming a hollow space that is in communication with a condensation channel that provides dehumidifying air;
a secondary window pane spaced apart from the primary window pane arrangement;
a window funnel that extends between the secondary window pane and the primary window pane arrangement; and
an intermediate space defined by the window funnel, the secondary window pane and the primary window pane arrangement that is sealed and includes an air inlet for introducing dehumidified air into the intermediate space,
wherein the hollow space and the intermediate space are fluidically connected.

11. The vehicle window of claim 10 , wherein the press-on frame further comprises a bore for producing the fluidic connection between the hollow space and the intermediate space.

12. The vehicle window of claim 10 , wherein the intermediate space is connected to a separate condensation channel that is formed in the vehicle window or on the vehicle window.

13. The vehicle window of claim 10 , wherein a sealing element is arranged between the window funnel and a boundary surface of the primary window pane arrangement which is directed toward the secondary pane.
