Abstract

A system controlling an access opening in a body of a vehicle includes a door arranged to selectively open and close a first portion of the opening. A latch is mounted on the door for latching the door to the body and releasing the door to selectively open and close the first portion of the opening. A device is mounted on the door and is configured to be retracted by an actuator before the door is opened and to be protracted by the actuator when the door is closed. A detent is mounted on the device to latch the device to the door when the device is protracted and to release the device before the device is retracted. A motor is mounted on the first door and is configured to operate at least two of the latch, the detent, and the actuator.

Claims

1. A system for controlling an access opening in a body of a vehicle, the system comprising:

a first door arranged to selectively open and close at least a first portion of the access opening;

a latch operatively connected to the first door and configured to selectively latch the first door to the body when at least the first portion of the opening is closed and release the first door to open at least the first portion of the opening;

a device operatively connected to the first door and configured to be retracted by an actuator before the first door is opened and to be protracted by the actuator when the first door is closed to thereby seal at least the first portion of the opening;

a detent operatively connected to the device, wherein the detent is configured to latch the device to the door when the device is protracted and to release the device from the door before the device is retracted; and

a motor operatively connected to the first door and configured to operate at least two of i) the latch to release the first door, ii) the detent to release the device from the door, and iii) the actuator to retract the device.

2. The system of claim 1, wherein the motor is additionally configured to operate the actuator to protract the device.

3. The system of claim 1, wherein the motor is further configured to coordinate the operation of the detent to release the device and the operation of the latch to release the first door.

4. The system of claim 3, wherein the motor releases the detent before releasing the latch.

5. The system of claim 1, further comprising a second door arranged to selectively open and close a second portion of the opening that remains open when the first door is closed.

6. The system of claim 5, wherein the device is adapted to seal the first door to the second door when the second door is closed.

7. The system of claim 6, wherein the device does not retract when the first door is closed and the second door is opened.

8. The system of claim 6, wherein the vehicle body is characterized by a front end, a rear end, and an absence of a B-pillar, and wherein:

the opening is an entryway on a side of the vehicle;

the at least a first portion of the opening is positioned toward the rear end of the vehicle and the second portion of the opening is positioned toward the front end of the vehicle;

the first door is rear-hinged; and

the second door is front-hinged.

9. The system of claim 1, wherein the first door includes a release mechanism configured to manually release the latch.

10. A vehicle comprising:

a body having a front end and a rear end, and defining an access opening; and

a system for sealing the opening having;

a first door arranged to selectively open and close at least a first portion of the opening;

a latch mounted on the first door and arranged to selectively latch the first door to the body when at least the first portion of the opening is closed and release the first door to open at least the first portion of the opening;

a device operatively connected to the first door and configured to be refracted by an actuator before the first door is opened and to be protracted by the actuator when the first door is closed to thereby seal at least the first portion of the opening;

a detent mounted on the device, the detent arranged to latch the device to the door when the device is protracted and operable to release the device from the door before the device is retracted; and

a motor operatively connected to the first door and configured to operate at least two of i) the latch to release the first door, ii) the detent to release the device from the door, and iii) the actuator to retract the device.

11. The vehicle of claim 10, wherein the motor is additionally configured to operate the actuator to protract the device.

12. The vehicle of claim 10, wherein the motor is further adapted to coordinate the operation of the detent to release the device and the operation of the latch to release the first door.

13. The vehicle of claim 10, wherein the motor releases the detent before releasing the latch.

14. The vehicle of claim 10, further comprising a second door arranged to selectively open and close a second portion of the opening that remains open when the first door is closed.

15. The vehicle of claim 14, wherein the device is adapted to seal the first door to the second door when the second door is closed.

16. The vehicle of claim 15, wherein the device does not retract when the first door is closed and the second door is opened.

17. The vehicle of claim 15, wherein the vehicle body is characterized by an absence of a B-pillar, and wherein:

the access opening is an entryway on a side of the vehicle;

the at least a first portion of the opening is positioned toward the rear end of the vehicle and the second portion of the opening is positioned toward the front end of the vehicle;

the first door is rear-hinged; and

the second door is front-hinged.

18. The system of claim 10, wherein the first door includes a release mechanism configured to manually release the latch.
