Abstract

A vehicle and method of operation having a first door, a second door, an inflatable door seal assembly and an inflator assembly. The first door has a first opening side and a first seal mount extending along the first opening side. The second door has a second opening side adjacent to the first opening side to define a gap and a second seal mount extending along the second opening side. The door seal assembly has a first seal assembly mounted to one of the first or second seal mounts, the first seal assembly inflatable to extend into the gap toward the other of the seal mounts when the first and second door are closed and deflatable to retract from the gap. The inflator assembly pumps a fluid into the seal assembly to inflate the seal assembly and pumps the fluid out to deflate the seal assembly.

Claims (22)

1. A vehicle comprising:

a first door having a first opening side, an opposed first hinge side pivotally supported by the vehicle and a first seal mount extending along at least a portion of the first opening side;

a second door having a second opening side adjacent to the first opening side to define a gap therebetween, an opposed second hinge side pivotally supported by the vehicle and a second seal mount extending along at least a portion of the second opening side;

an inflatable door seal assembly having a first seal assembly mounted to one of the first or second seal mounts, the first seal assembly configured to be inflatable to extend into the gap toward the other of the first or second seal mounts when the first and second door are closed and deflatable to retract from the gap; and

an inflator assembly configured to pump a fluid into the first seal assembly to inflate the first seal assembly and pump the fluid out of the first seal assembly to deflate the first seal assembly; and

wherein the first seal assembly includes a first inflator seal mounted to the first seal mount and configured to operatively engage the inflator assembly to be selectively inflated and deflated, a first carrier channel mounted to the first inflator seal and configured to be telescopically slidable toward and away from the gap by the inflation and deflation, respectively, of the first inflator seal, and a first primary seal mounted to the first carrier channel and configured to be slidable toward and away from the gap.

2. The vehicle of claim 1 wherein the inflatable door seal assembly includes a second seal assembly mounted to the other of the first or second seal mounts and configured to selectively seal against the first seal assembly to seal the gap.

3. The vehicle of claim 2 wherein the second seal assembly is a fixed seal.

4. The vehicle of claim 2 wherein the second seal assembly is configured to be inflatable to extend into the gap toward the first seal assembly, and the inflator assembly is configured to pump the fluid into the second seal assembly to inflate the second seal assembly and pump the fluid out of the second seal assembly to deflate the second seal assembly.

5. The vehicle of claim 2 wherein the second seal mount is a second seal pocket and the second seal assembly is secured in the second seal pocket.

6. The vehicle of claim 2 wherein the second seal assembly includes a second inflator seal mounted to the second seal mount and configured to operatively engage the inflator assembly to be selectively inflated and deflated, a second carrier channel mounted to the first inflator seal and configured to be telescopically slidable toward and away from the gap by the inflation and deflation, respectively of the second inflator seal, and a second primary seal mounted to the second carrier channel and configured to be slidable toward and away from the gap and selectively engage the first seal assembly.

7. The vehicle of claim 2 including a controller in communication with the inflator assembly, and wherein the first door includes a first door handle in communication with the controller, and the second door includes a second door handle in communication with the controller.

8. The vehicle of claim 7 including a first door closed sensor in communication with the first door and configured to communicate with the controller that the first door is in a closed position, and a second door closed sensor in communication with the second door and configured to communicate with the controller that the second door is in a closed position.

9. The vehicle of claim 1 including a controller in communication with the inflator assembly, and wherein the first door includes a door handle in communication with the controller.

10. The vehicle of claim 9 including a first door closed sensor in communication with the first door and configured to communicate with the controller that the first door is in a closed position.

11. A vehicle comprising:

a first door having a first opening side, an opposed first hinge side pivotally supported by the vehicle and a first seal mount extending along at least a portion of the first opening side;

a second door having a second opening side adjacent to the first opening side to define a gap therebetween, an opposed second hinge side pivotally supported by the vehicle and a second seal mount extending along at least a portion of the second opening side;

an inflatable door seal assembly having a first seal assembly mounted to one of the first or second seal mounts, the first seal assembly configured to be inflatable to extend into the gap toward the other of the first or second seal mounts when the first and second door are closed and deflatable to retract from the gap; and

an inflator assembly configured to pump a fluid into the first seal assembly to inflate the first seal assembly and pump the fluid out of the first seal assembly to deflate the first seal assembly;

wherein the inflatable door seal assembly includes a second seal assembly mounted to the other of the first or second seal mounts and configured to selectively seal against the first seal assembly to seal the gap; and

wherein the first seal assembly includes a first inflator seal mounted to the first seal mount and configured to operatively engage the inflator assembly to be selectively inflated and deflated, a first carrier channel mounted to the first inflator seal and configured to be telescopically slidable toward and away from the gap by the inflation and deflation, respectively, of the first inflator seal, and a first primary seal mounted to the first carrier channel and configured to be slidable toward and away from the gap and selectively engage the second seal assembly; and the second seal assembly includes a second inflator seal mounted to the second seal mount and configured to operatively engage the inflator assembly to be selectively inflated and deflated, a second carrier channel mounted to the first inflator seal and configured to be telescopically slidable toward and away from the gap by the inflation and deflation, respectively of the second inflator seal, and a second primary seal mounted to the second carrier channel and configured to be slidable toward and away from the gap and selectively engage the first seal assembly.
