Abstract
Abstract An automotive vehicle has a passenger compartment provided in a window opening provided with a windowpane which is electrically conductive at least on the side facing the interior of the compartment. At least one air supply channel is provided which discharges a stream of air along the inner side of the window and an ion-producing device is provided in the channel upstream of the window for enriching the stream of air with ions. An arrangement may also be provided for establishing and maintaining the interior of the compartment an electrostatic field.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
145 words
In a vehicle, particularly an automotive vehicle, in combination, a body surrounding a passenger compartment and including at least one window opening; at least one air supply channel oriented for discharging a stream of air in said passenger compartment across said opening; an ion-producing device associated with said channel upstream of said window opening for enriching the stream of air with ions; electric field producing means for producing an electric field in said compartment; and a winDowpane in said window opening provided with electrically conductive means rendering said windowpane conductive at least along its side facing the interior of said compartment, and connected to said electric field producing means and maintained by the same at an electric potential requisite for repelling ions of a desired polarity, whereby to disperse the latter in said compartment, while serving as a catch electrode for ions of undesired polarity.
Claim 2
Dependent Claim
145 words
In a vehicle, particularly an automotive vehicle, in combination, a body surrounding a passenger compartment and including at least one window opening; at least one air supply channel oriented for discharging a stream of air in said passenger compartment across said opening; an ion-producing device associated with said channel upstream of said window opening for enriching the stream of air with ions; electric field producing means for producing an electric field in said compartment; and a winDowpane in said window opening provided with electrically conductive means rendering said windowpane conductive at least along its side facing the interior of said compartment, and connected to said electric field producing means and maintained by the same at an electric potential requisite for repelling ions of a desired polarity, whereby to disperse the latter in said compartment, while serving as a catch electrode for ions of undesired polarity.
Claim 3
Dependent Claim
35 words
In a vehicle as defined in claim 1, and further comprising at least one counter electrode in said vehicle cooperating with said windowpane and having a potential which is higher than that of said windowpane.
Claim 4
Dependent Claim
43 words
In a vehicle as defined in claim 2, said passenger compartment having a ceiling; and wherein said counterelectrode is a ceiling electrode mounted in the region of said ceiling, said field producing means producing between said windowpane and said counterelectrode an electric field.
Claim 5
Dependent Claim
29 words
In a vehicle as defined in claim 3, said body being at least predominantly of electrically conductive material; and wherein said window pane is conductively connected with said body.
Claim 6
Dependent Claim
43 words
In a vehicle as defined in claim 1, said body being at least predominantly of electrically conductive material at a predetermined electric potential; and further comprising an additional electrode within said passenger compartment and having a lower electric potential than said predetermined potential.
Claim 7
Dependent Claim
27 words
In a vehicle as defined in claim 5, said passenger compartment having a floor; and wherein said additional electrode is provided in the region of said floor.
Claim 8
Dependent Claim
28 words
In a vehicle as defined in claim 5; further comprising at least one seat in said passenger compartment; and wherein said additional electrode is provided on said seat.
Claim 9
Dependent Claim
18 words
In a vehicle as defined in claim 5; and insulating means electrically insulating said windowpane from said body.
Claim 10
Dependent Claim
74 words
In a vehicle as defined in claim 1; said field producing means comprising a source of electric energy; and a high-ohmic resistor interposed in circuit between said source and said windowpane. 10. In a vehicle as defined in claim 1, said windowpane comprising at least one outer layer of electrically insulating transparent material having an inner side facing said passenger compartment, and an inner layer of transparent electrically conductive material on said inner side.
Claim 11
Dependent Claim
16 words
In a vehicle as defined in claim 10, wherein said inner layer is an anti-reflection material.
Claim 12
Dependent Claim
63 words
In a vehicle as defined in claim 1, further comprising a pair of additional electrodes spaced from each other, said field producing means comprising a source of electrical energy having a positive pole and a negative pole each connected to one of said additional electrodes to establish therebetween an electric field in said compartment, and further having a tap connected to said windowpane.
