System and method for actuating multiple components in a vehicle having an access opening
An actuating system for a vehicle having a body that defines an access opening includes a panel arranged to selectively open and close at least a first portion of the opening. The system also includes multiple components operatively connected to the panel and adapted to be actuated. The system additionally includes a motor operatively connected to the panel and adapted to actuate the multiple components. A vehicle employing the system and a method for sealing an access opening in a body of a vehicle are also provided.
1. An actuating system for a vehicle having a body that defines an access opening, the system comprising:
a first door arranged to selectively open and close at least a first portion of the opening;
a window operatively connected to the first door and arranged to be adjusted for height;
a device operatively connected to the first door and configured to retract when the first door is opened and protract when the first door is closed to thereby seal the at least a first portion of the opening;
a window regulator motor mounted on the first door and configured to adjust the height of the window and selectively retract and protract the device; and
a clutch operatively connected to each of the window regulator motor, the window, and the device, wherein the clutch is configured to operate the window regulator motor in a first mode of adjusting the height of the window and selectively retracting and protracting the device, a second mode of adjusting the height of the window without operating the device, and a third mode of selectively retracting and protracting the device without adjusting the height of the window.
2. The system of claim 1 , wherein the clutch employs a shape memory alloy material selectively energized to operate the window regulator motor in one of the first, second, and third modes.
3. The system of claim 1 , wherein the clutch is connected to the device via at least one of a torque transmitting cable and a linear force transmitting cable.
4. 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.
5. The system of claim 4 , wherein the device is adapted to seal the first door to the second door when the second door is closed.
6. The system of claim 5 , 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.
7. 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, the system having:
a first door arranged to selectively open and close at least a first portion of the opening;
a window mounted on the first door and arranged to be adjusted for height;
a device operatively connected to the first door and configured to retract when the first door is opened and protract when the first door is closed to thereby seal the at least a first portion of the opening;
a window regulator motor operatively connected to the first door and configured to adjust the height of the window and selectively retract and protract the device; and
a clutch operatively connected to each of the window regulator motor, the window, and the device, wherein the clutch is configured to operate the window regulator motor in a first mode of adjusting the height of the window and selectively retracting and protracting the device, a second mode of adjusting the height of the window without operating the device, and a third mode of selectively retracting and protracting the device without adjusting the height of the window.
8. The vehicle of claim 7 , wherein the clutch employs a shape memory alloy material selectively energized to operate the window regulator motor in one of the first, second, and third modes.
9. The vehicle of claim 7 , wherein the clutch is connected to the device via at least one of a torque transmitting cable and a linear force transmitting cable.
10. The vehicle of claim 7 , 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.
11. The vehicle of claim 10 , wherein the device is adapted to seal the first door to the second door when the second door is closed.
12. The vehicle of claim 11 , 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.
13. A method for sealing an access opening in a body of a vehicle having a front end and a rear end, the method comprising:
unlatching a first door that is arranged to selectively open and close a first portion of the opening, the door having a window that is arranged to be adjusted for height by a window regulator motor;
detecting whether the first door has been unlatched;
retracting a device operatively connected to the first door by the window regulator motor such that the first door may be opened to uncover the at least a first portion of the opening, wherein the device is adapted to seal the first door against a second door that is arranged to selectively open and close a second portion of the opening that remains open when the first door is closed; and
operating the window regulator motor via a clutch, wherein the clutch is configured to operate the window regulator motor in a first mode of adjusting the height of the window and selectively retracting and protracting the device, a second mode of adjusting the height of the window without operating the device, and a third mode of selectively retracting and protracting the device without adjusting the height of the window.
14. The method of claim 13 , further comprising:
detecting whether the second door is closed;
closing the first door to cover the at least a first portion of the opening; and
protracting the device by the window regulator motor to seal the first door against the second door when the second door is closed.
15. The method of claim 13 , wherein the clutch employs a shape memory alloy material, and said operating of the window regulator motor is accomplished by selectively energizing the shape memory alloy material.
16. The method of claim 13 , 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.
