Mechanisms and methods to prevent debris from entering a vehicle cabin
A pickup truck includes a cab having a rear wall and a rear window positioned in the rear wall. An airflow duct extends along a portion of the cab. The airflow duct has an inlet and an outlet and defines an airflow passage extending between the inlet and the outlet. The outlet is positioned rearwardly of the cab and within a space defined by a first horizontal plane extending through an edge of the rear window and a second horizontal plane spaced apart a predetermined distance from the first horizontal plane in a direction away from the rear window.
1. A pickup truck comprising:
a cab, the cab including a rear wall and a rear window positioned in the rear wall; and
an airflow duct extending along a portion of the cab, the airflow duct having an inlet, an outlet, and an airflow passage extending between the inlet and the outlet, wherein the outlet is positioned rearwardly of the cab and within a space defined by a first horizontal plane extending through an edge of the rear window and a second horizontal plane spaced apart a predetermined distance from the first horizontal plane in a direction away from the rear window.
2. The pickup truck of claim 1 wherein the outlet is structured so that an air stream exiting the outlet is spaced apart from the rear window and exits the outlet in a direction parallel to a plane of the rear window.
3. The pickup truck of claim 1 wherein the outlet is structured so that an air stream exiting the outlet is directed rearwardly of the outlet.
4. The pickup truck of claim 3 wherein the outlet is structured so that an air stream exiting the outlet is directed upwardly of the outlet.
5. The pickup truck of claim 3 wherein the outlet is structured so that an air stream exiting the outlet is directed downwardly of the outlet.
6. The pickup truck of claim 1 wherein the outlet extends parallel to a width dimension of a portion of the rear window structured to be openable, and wherein the outlet has a length dimension at least equal to the width dimension.
7. The pickup truck of claim 1 wherein at least a portion of the airflow duct extends along a roof of the cab.
8. The pickup truck of claim 1 wherein at least a portion of the airflow duct extends along an underside of the cab.
