Abstract

A system according to an exemplary aspect of the present disclosure includes, among other things, a door having interior and exterior sides, at least one inlet in the interior side, at least one outlet in the exterior side, and a window mechanism to move a window relative to the door. At least one pressure relief valve is in communication with the inlet and outlet, and is mechanically linked for movement with the window. A method according to an exemplary aspect of the present disclosure includes, among other things, mechanically linking at least one pressure relief valve for movement with the window such that the pressure relief valve opens in response to the window beginning to open.

First claim

What is claimed is:

1. A system, comprising:
a door having interior and exterior sides;
at least one inlet in the interior side and at least one outlet in the exterior side;
a window mechanism to move a window relative to the door; and
at least one pressure relief valve in communication with the inlet and outlet, and being mechanically linked for movement with the window.

2. The system according to claim 1 , wherein the pressure relief valve is closed when the window is closed and is opened when the window begins to open to allow air to flow from the inlet to the outlet.

3. The system according to claim 2 , wherein the window mechanism automatically lowers the window by a predetermined amount in response to the door being opened.

4. The system according to claim 3 , wherein the window mechanism closes the window once the door is closed and the pressure relief valve returns to a closed position.

5. The system according to claim 2 , including a gear assembly that couples the window mechanism and/or window to the pressure relief valve.

6. The system according to claim 2 , including a cam assembly that couples the window mechanism and/or window to the pressure relief valve.

7. The system according to claim 1 , wherein the at least one inlet comprises at least one louver or vent hole located in door trim on the interior side.

8. The system according to claim 1 , including a vertically extending J-plane separating the interior and exterior sides, and wherein the inlet is located internally and the outlet is located externally relative to the J-plane.

9. The system according to claim 8 , wherein the pressure relief valve is located internally relative to the J-plane.

10. The system according to claim 9 , wherein the pressure relief valve comprises a first pressure relief valve and including at least one second pressure relief valve located externally relative to the J-plane and associated with the outlet.

11. The system according to claim 10 , wherein the second pressure relief valve is mechanically coupled to the first pressure relief valve.

12. The system according to claim 1 , including a seal associated with the outlet.

13. The system according to claim 12 , wherein the seal is preloaded to a closed position and moves to an open position in response to an increase in air pressure exiting the pressure relief valve.

14. The system according to claim 1 , wherein the at least one pressure relief valve comprises at least a first pressure relief valve associated with the inlet and a second pressure relief valve associated with the outlet, the first and second pressure relief valves being mechanically linked for movement together between open and closed positions.

15. A method, comprising:
providing a door having interior and exterior sides, a window mechanism to move a window relative to the door, and at least one inlet in the interior side and at least one outlet in the exterior side; and
mechanically linking at least one pressure relief valve for movement with the window such that the pressure relief valve opens in response to the window beginning to open.

16. The method according to claim 15 , including automatically lowering the window via the window mechanism by a predetermined amount in response to the door being opened which correspondingly opens the pressure relief valve to allow air to flow from the inlet to the outlet.

17. The method according to claim 16 , including closing the window via the window mechanism once the door is closed resulting in the pressure relief valve returning to a closed position.

18. The method according to claim 17 , including coupling the pressure relief valve to the window mechanism and/or window with a gear or cam assembly.

19. The method according to claim 17 , wherein the at least one pressure relief valve comprises at least a first pressure relief valve and a second pressure relief valve, and including associating the first pressure relief valve with the inlet, associating the second pressure relief valve with the outlet, and mechanically linking the first and second pressure relief valves for movement together between open and closed positions.

20. The method according to claim 17 , including providing a seal at the outlet and preloading the seal to a closed position.

21. The method according to claim 15 , including forming the door as a panel structure that receives the window as the window is opened, and fixing the at least one inlet and the at least one outlet within the panel structure.

22. The system according to claim 1 , wherein the door is formed as a panel structure that receives the window as the window is opened, and wherein the at least one inlet and the at least one outlet are fixed within the panel structure.
