Abstract

An automobile air vent register is described. The register uses a single set of vanes, a rotating vent cover, and an elongate opening in a configuration providing good air flow control within a limited space.

First claim

What is claimed is:

1. A vehicle air register, comprising:
an airflow path through an opening from a duct to a vehicle interior, the opening having length and width, wherein the length is at least three times the width;
a cover, having a partition separating a compartment from the airflow path, and wherein the cover is configured to rotate between closed and open, wherein the closed cover is semi-cylindrical on a surface facing the vehicle interior and covers the opening, and wherein the cover rotates around a pivot point; and
a plurality of vanes oriented substantially perpendicular to the length of the register, wherein no portion of the plurality of vanes extends toward the vehicle interior past the pivot point.

2. The register of claim 1 , wherein the cover is configured to rotate 120 degrees between a closed position and an open position.

3. The register of claim 1 further comprising:
a vane control, wherein the vane control is configured to pivot the vanes by a linear actuator; and
a cover control, wherein the cover control is configured to rotate the cover to a closed, open, or partly-open position.

4. The register of claim 3 , wherein the linear actuator is a rack and pinion system and wherein the rack is substantially enclosed within the compartment.

5. The register of claim 1 , wherein the cover is a single piece of material.

6. The register of claim 1 , wherein the length is at least four times the width.

7. The register of claim 1 , wherein the length is at least five times the width.

8. The register of claim 1 , wherein the opening width is less than half of a width of the duct.

9. The register of claim 8 , further comprising: at least two splitter fins placed along the airflow path between the duct and the opening.

10. The register of claim 1 , wherein the partition defines a partition surface configured to direct the airflow when the cover is in the open or a partly-open position.

11. The register of claim 10 , wherein the partition surface has an area in a range of about 24-48 cm.

12. The register of claim 10 , wherein the partition surface is curved.

13. A vehicle air register, comprising:
an airflow path through an opening from a duct to a vehicle interior, the opening having length and width, wherein the length is five to fifteen times the width;
a cover, having a partition separating a compartment from the airflow path, and wherein the cover is configured to rotate between closed and open, wherein the closed cover is semi-cylindrical on a surface facing the vehicle interior and covers the opening, and wherein the cover rotates around a pivot point; and
a plurality of vanes oriented substantially perpendicular to the length of the register, wherein no portion of the plurality of vanes extends toward the vehicle interior past the pivot point.

14. The register of claim 13 , wherein the partition defines a partition surface configured to direct the airflow when the cover is in the open or a partly-open position.

15. The register of claim 14 , wherein the partition surface has an area in a range of about 24-48 cm.

16. The register of claim 14 , wherein the partition surface is curved.
