Abstract
Abstract A ventilation device for a vehicle roof window disposed in a window opening having a light-permeable cover (6). The cover is adjustably movable between at least one open and one closed position. The ventilation device consists of at least one motor-driven fan (8, 4). At least one support (22, 24) can be fastened stationary on the vehicle body, for the arrangement of the fan on the vehicle interior side of the cover, within the window opening. A power source (14) is provided for the fan motor (8). The power source is at least one solar cell and this solar cell is arranged between the light-permeable cover (6) and the at least one support (22, 24).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
223 words
A sun roof for location in an opening in the roof of a vehicle and defining a window through which light and air are able to enter the vehicle interior, said sun roof comprising: frame means to be supported by the vehicle roof and defining the window including an unobstructed window area for the penetration of air and light therethrough; a translucent cover for the window including said unobstructed window area and movable between an open position in which air may enter the vehicle interior through the unobstructed window area and a closed position in which it blocks entry of air into the vehicle interior through the window; a ventilation device supported by said frame means and located in the window adjacent said unobstructed window area, said ventilation device comprising: fan blades, a motor for driving said fan blades, a support portion located under said translucent cover for supporting said motor and said fan blades on the vehicle interior side of said cover, said fan blades and said motor being spaced laterally away from said unobstructed window area, and a power source for said motor, said power source comprising at least one solar cell located between said translucent cover and said support portion; the area of said unobstructed window area being greater than the area of the window occupied by said ventilation device.
