Abstract

An air handling system for a heating, ventilation, and air conditioning system of a motor vehicle having a passenger compartment, includes a main housing having a first mode door rotatably disposed therein and a second mode door rotatably disposed therein. An actuator drives the first mode door. A control mechanism is disposed within the housing and is configured to control a simultaneous rotational position of each of the first mode door and the second mode door.

First claim

What is claimed is:

1. An air handling system for a heating, ventilation, and air conditioning system of a motor vehicle having a passenger compartment, the air handling system comprising:
a main housing having a first mode door rotatably disposed therein and a second mode door rotatably disposed therein, an axis of rotation of the first mode door and an axis of rotation of the second mode door each extending in a lateral direction of the main housing, the main housing including a first chamber, a second chamber, and a third chamber, a divider of the main housing separating the first chamber from the second chamber with respect to the lateral direction of the main housing, the third chamber positioned in the lateral direction of the main housing to be continuous with the first chamber and the second chamber, wherein the first mode door is rotatably disposed within each of the first chamber and the second chamber, and wherein the second mode door is rotatably disposed within the third chamber;
an actuator operating the first mode door; and
a control mechanism disposed within the main housing and configured to control a simultaneous rotational position of each of the first mode door and the second mode door, wherein the control mechanism is a single component having a first portion, a second portion, and a rotatable portion about which the control mechanism rotates disposed intermediate the first portion and the second portion, wherein each of the first portion and the second portion has a cross-sectional shape substantially corresponding to a sector of a circle having a central angle of less than 180 degrees wherein a teeth are placed on the first and the second portion only.

2. The air handling system of claim 1 , wherein the control mechanism is rotatably coupled to an inner surface of the main housing.

3. The air handling system of claim 1 , wherein the first mode door is spaced from the second mode door, the actuator directly connected to only the first mode door.

4. The air handling system of claim 1 , wherein the first portion of the control mechanism directly engages the first mode door and the second portion of the control mechanism directly engages the second mode door.

5. The air handling system of claim 1 , wherein the teeth of the first portion of the control mechanism are formed in an outer circumferential surface thereof, the teeth of the first portion engaging the first mode door, and wherein the teeth of the second portion of the control mechanism are formed in an outer circumferential surface thereof, the teeth of the second portion engaging the second mode door.

6. The air handling system of claim 5 , wherein the first mode door has a gear link having teeth formed thereon, the teeth of the first mode door engaging the teeth formed in the outer circumferential surface of the first portion of the control mechanism, wherein the second mode door has a gear link having teeth formed thereon, the teeth of the second mode door engaging the teeth formed in the outer circumferential surface of the second portion of the control mechanism.

7. The air handling system of claim 6 , wherein the gear link of the first mode door is integrally formed with the first mode door and the gear link of the second mode door is integrally formed with the second mode door.

8. The air handling system of claim 1 , wherein the rotatable portion is configured as a ring.

9. The air handling system of claim 1 , wherein the control mechanism is rotatably coupled to the divider.

10. The air handling system of claim 1 , wherein the divider includes a clip feature coupling the control mechanism to the divider.

11. The air handling system of claim 1 , wherein the control mechanism includes a series of gears providing rotational communication between the first mode door and the second mode door.

12. An air handling system for a heating, ventilation, and air conditioning system of a motor vehicle having a passenger compartment, the air handling system comprising:
a main housing divided into a first chamber, a second chamber, and a third chamber, the main housing including a first mode door rotatably disposed therein extending within the first chamber and the second chamber, and a second mode door rotatably disposed therein extending within the third chamber, an axis of rotation of the first mode door and an axis of rotation of the second mode door each extending in a lateral direction of the main housing, a divider of the main housing separating the first chamber from the second chamber with respect to the lateral direction of the main housing, the third chamber positioned in the lateral direction of the main housing to be continuous with the first chamber and the second chamber;
an actuator operating the first mode door; and
a control mechanism disposed within the main housing and configured to control a simultaneous rotational position of each of the first mode door and the second mode door, wherein the control mechanism is a single component having a first portion, a second portion, and a rotatable portion about which the control mechanism rotates disposed intermediate the first portion and the second portion, wherein each of the first portion and the second portion has a cross-sectional shape substantially corresponding to a sector of a circle having a central angle of less than 180 degrees wherein a teeth are placed on the first and the second portion only.

13. The air handling system of claim 12 , wherein the control mechanism is coupled to the divider.

14. The air handling system of claim 13 , wherein the control mechanism is coupled to a clip feature extending outwardly from a surface of the divider.

15. The air handling system of claim 14 , wherein the clip feature is integrally formed with the divider.

16. An air handling system for a heating, ventilation, and air conditioning system of a motor vehicle having a passenger compartment, the air handling system comprising:
a main housing divided into a first chamber, a second chamber, and a third chamber, the main housing including a first mode door rotatably disposed therein extending within the first chamber and the second chamber, and a second mode door rotatably disposed therein extending within the third chamber, the first mode door having a gear link formed thereon and the second mode door having a second gear link formed thereon, an axis of rotation of the first mode door and an axis of rotation of the second mode door each extending in a lateral direction of the main housing, a divider of the main housing separating the first chamber from the second chamber with respect to the lateral direction of the main housing, the third chamber positioned in the lateral direction of the main housing to be continuous with the first chamber and the second chamber;
an actuator operating the first mode door; and
a control mechanism disposed within the main housing and cooperating with the gear link of the first mode door and the gear link of the second mode door to provide simultaneous rotational communication between the first mode door and the second mode door, the control mechanism coupled to a clip feature extending outwardly from an internal surface of the main housing, wherein the control mechanism is a single component having a first portion, a second portion, and a rotatable portion about which the control mechanism rotates disposed intermediate the first portion and the second portion, wherein each of the first portion and the second portion has a cross-sectional shape substantially corresponding to a sector of a circle having a central angle of less than 180 degrees wherein a
