ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to windows for vehicles and, more specifically, to an insulated window system for a vehicle.
2. Description of the Related Art
It is known to provide a window for a vehicle such as a windshield for a front opening in a vehicle body of a motor vehicle. Typically, the windshield includes two glass panels or sheets laminated to each other by an adhesive film or interlayer therebetween. Additionally, the window may be a side window for a side opening in the vehicle body. The side window is typically a single glass panel or sheet.
It is also known to provide a climate control system for a vehicle for heating and cooling of an occupant compartment of the vehicle body of the motor vehicle. It is further known that glass panels are susceptible to heat transfer. As a result, convective losses through the glass panels of the windows are a major contributor to the thermal load on the climate control system of the vehicle.
Although the above windows have worked, it is desirable to improve the thermal resistances of the windows for a vehicle. It is also desirable to provide a dual pane window for a vehicle. It is further desirable to provide an insulated window system for a vehicle. Therefore, there is a need in the art to provide a window system for a vehicle that meets these desires.
SUMMARY OF THE INVENTION
Accordingly, the present invention is an insulated window system for a vehicle including a first wall of plastic material disposed in a window opening of the vehicle. The insulated window system also includes a second wall of plastic material disposed in the window opening and spaced a predetermined distance from the first wall to form a gap therebetween.
One advantage of the present invention is that an insulated window system is provided for a vehicle to improve performance and NVH of the vehicle. Another advantage of the present invention is that the insulated window system is an insulated dual wall polycarbonate window, which is constructed in a one shot injection molding process. Yet another advantage of the present invention is that the insulated window system is approximately the same weight as single pane glass units but has thermal resistances on an order of magnitude larger. Still another advantage of the present invention is that the insulated window system greatly reduces the thermal load on the climate control system of the vehicle. A further advantage of the present invention is that insulated window system improves climate control performance with a subsequent increase in fuel economy of the vehicle.
Other features and advantages of the present invention will be readily appreciated, as the same becomes better understood, after reading the subsequent description when taken in conjunction with the accompanying drawings.
