Abstract

A heating, ventilation, and air conditioning (HVAC) assembly. The HVAC assembly includes a first shaft and a first airflow door movable by the first shaft. A second shaft and a second airflow door movable by the second shaft are also included. A case houses the first airflow door and the second airflow door. A cap is coupled to both the first shaft and the second shaft outside of the case. Rotation of the cap simultaneously rotates the first shaft and the second shaft.

First claim

What is claimed is:

1. A heating, ventilation, and air conditioning (HVAC) assembly comprising:
a first shaft, and a first airflow door movable by the first shaft;
a second shaft, and a second airflow door movable by the second shaft;
a case housing the first airflow door and the second airflow door; and
a cap coupled to both the first shaft and the second shaft outside of the case, the cap defines a receptacle and a recess that are concentrically aligned with each other, the first shaft is received within the receptacle and terminates within the cap, and the second shaft is received within the recess, wherein rotation of the cap simultaneously rotates the first shaft and the second shaft.

2. The HVAC assembly of claim 1 , wherein the first shaft extends through the second shaft.

3. The HVAC assembly of claim 1 , wherein the cap is keyed to both the first shaft and the second shaft.

4. The HVAC assembly of claim 1 , wherein the first shaft and the second shaft are not keyed to each other.

5. The HVAC assembly of claim 1 , wherein the cap includes a plurality of teeth for cooperation with a gear such that rotation of the gear rotates the cap.

6. The HVAC assembly of claim 1 , wherein both the first shaft and the second shaft extend within the housing, and extend out from within the housing to engage the cap.

7. The HVAC assembly of claim 1 , wherein the first airflow door controls airflow to a rear zone of a vehicle.

8. The HVAC assembly of claim 1 , wherein the second airflow door controls airflow towards a driver of a vehicle.

9. The HVAC assembly of claim 8 , further comprising:
a third shaft; and
a third airflow door movable by the third shaft;
wherein the third airflow door controls airflow towards a passenger of the vehicle.

10. The HVAC assembly of claim 9 , wherein the third shaft is movable independent of both the first shaft and the second shaft.

11. The HVAC assembly of claim 9 , wherein the first airflow door is arranged in the case between the second airflow door and the third airflow door.

12. A heating, ventilation, and air conditioning (HVAC) assembly for a vehicle, the HVAC assembly comprising:
a first shaft, and a first airflow door movable by the first shaft, the first airflow door controls airflow to a rear zone of the vehicle;
a second shaft, and a second airflow door movable by the second shaft, the second airflow door controls airflow to a driver's side zone of the vehicle;
a third shaft, and a third airflow door movable by the third shaft, the third airflow door controls airflow to a front passenger's side zone of the vehicle;
a case housing the first airflow door, the second airflow door, and the third airflow door; and
a cap coupled to both the first shaft and the second shaft outside of the case, the cap defines a receptacle and a recess that are concentrically aligned with each other, the first shaft is received within the receptacle and terminates within the cap, and the second shaft is received within the recess, wherein rotation of the cap simultaneously rotates the first shaft and the second shaft without rotating the third shaft.

13. The HVAC assembly of claim 12 , wherein the first shaft extends through the second shaft.

14. The HVAC assembly of claim 12 , wherein the cap is keyed to both the first shaft and the second shaft, and the third shaft rotates independent of the first shaft and the second shaft.

15. The HVAC assembly of claim 12 , wherein the first shaft and the second shaft are not keyed to each other.

16. The HVAC assembly of claim 12 , wherein the cap includes a plurality of teeth for cooperation with a gear such that rotation of the gear rotates the cap.

17. The HVAC assembly of claim 12 , wherein both the first shaft and the second shaft extend within the housing, and extend out from within the housing to engage the cap.

18. The HVAC assembly of claim 12 , wherein the first airflow door is arranged in the case between the second airflow door and the third airflow door.
