Windshield defroster with secondary ducted outlet

1. A defroster, comprising:

an inlet for receiving an air flow;

at least two sections, a first section of the at least two sections attached to a second section of the at least two sections such that the first and second sections of the at least two sections define the inlet and a primary chamber;

a wall dividing the air flow entering the inlet into a primary airflow through said primary chamber and a secondary airflow through a secondary chamber, wherein a central portion of said wall curves toward the primary chamber to optimize a cross section area taken by the secondary chamber at the inlet, such that an airflow volume of the primary airflow and an airflow volume of the secondary airflow are different;

a primary duct guiding the primary airflow out a primary outlet onto a first portion of a windshield extending from a passenger side edge of the windshield to a first area in line with a steering wheel in a longitudinal direction of the vehicle; and

a secondary duct guiding the secondary airflow out a secondary outlet onto a second portion of said windshield extending from a driver side edge of the windshield to a second area in line with the steering wheel in the longitudinal direction of the vehicle.

2. The defroster of claim 1 , wherein said at least two sections further form at least one side window defrost duct.

3. A defroster, comprising:

an inlet for receiving an air flow;

first and second sections, the first section attached to the second section such that the first and second sections define the inlet and a primary chamber;

a wall dividing the entering the inlet air flow into a primary airflow through said primary chamber and a secondary airflow through a secondary chamber, wherein a central portion of said wall curves toward the primary chamber to optimize a cross section area taken by the secondary chamber at the inlet, such that an airflow volume of the primary airflow and an airflow volume of the secondary airflow are different;

a primary duct guiding the primary airflow from said primary chamber out a primary outlet onto a first portion of a windshield extending from a passenger side edge of the windshield to a first area in line with a steering wheel in a longitudinal direction of the vehicle;

a secondary duct guiding the secondary airflow from said secondary chamber out a secondary outlet onto a second portion of said windshield extending from a driver side edge of the windshield to a second area in line with the steering wheel in the longitudinal direction of the vehicle; and

a tertiary duct guiding a tertiary airflow toward a side window.

4. The defroster of claim 3 , wherein said central portion of the wall curving toward the primary chamber proportions the air flow into the primary airflow and the secondary airflow.

5. The defroster of claim 3 , wherein the tertiary duct is one of a driver side window duct and a passenger side window duct.

6. A defroster, comprising:

a first section attached to a second section;

an inlet for receiving an air flow, the inlet defined by the first and the second sections;

a wall extending from the first section divides the air flow entering the inlet into a primary airflow and a secondary airflow;

a primary chamber receiving the primary airflow and a secondary chamber receiving the secondary airflow, wherein a central portion of said wall curves toward the primary chamber to optimize a cross section area taken by the secondary chamber at the inlet, such that an airflow volume of the primary airflow and an airflow volume of the secondary airflow are different;

a primary duct guiding the primary airflow out a primary outlet onto a first portion of a windshield, said first portion of the windshield extends from a passenger side edge of the windshield to a first area in line with a steering wheel in a longitudinal direction of the vehicle; and

a secondary duct guiding the secondary airflow out a secondary outlet onto a second portion of said windshield, said second portion extends from a driver side edge of the windshield to a second area in line with the steering wheel in the longitudinal direction of the vehicle, wherein the first portion and the second portion of the windshield overlap to eliminate any gaps in the primary airflow and secondary airflow onto the windshield.

7. The defroster of claim 6 , wherein said primary chamber is defined by the first section and the second section.

8. The defroster of claim 6 , wherein said central portion of said wall extends toward the second section.

9. The defroster of claim 6 , wherein said first section and said second section define a tertiary duct guiding a tertiary portion of the air flow toward a side window.

10. A vehicle incorporating the defroster of claim 6 .
