Control of an access opening in a body of a vehicle
A system for controlling an access opening in a vehicle body includes first and second doors arranged to selectively open and close first and second portions of the opening. The system also includes a device operatively connected to the first door and configured to be selectively retracted before at least one of the first and second doors is opened. The device is also configured to be protracted when the first and second doors are closed to thereby seal the first and second portions of the access opening. The system additionally includes a controller configured to selectively retract and protract the device. Furthermore, the system includes a sensor arranged on the vehicle and configured to detect an impact exceeding a threshold intensity on the body and communicate a signal indicative of the impact to the controller. The controller retracts the device upon receipt of the signal from the sensor.
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 a first portion of the access opening;
a second door arranged to selectively open and close a second portion of the access opening;
a device operatively connected to the first door and configured to be selectively retracted before at least one of the first and second doors is opened and protracted when the first and second doors are closed to thereby seal the first and second portions of the access opening;
a detent operatively connected to the device and configured to latch the device to the first door when the device is protracted and release the device from the first door before the device is retracted;
a controller arranged on the body and configured to selectively retract and protract the device; and
a sensor arranged on the vehicle and configured to detect an impact exceeding a threshold intensity on the body and communicate a signal indicative of the impact to the controller;
wherein the controller retracts and releases the device via the detent upon receipt of the signal from the sensor.
2. The system of claim 1 , wherein the sensor is an accelerometer configured to sense the force of the impact.
3. The system of claim 2 , wherein the signal from the accelerometer is additionally configured to trigger a supplemental inflatable restraint in the vehicle.
4. The system of claim 1 , wherein the sensor is one of a radar, laser, and camera configured to sense an imminent occurrence of the impact.
5. The system of claim 4 , wherein the device is refracted prior to the impact.
6. The system of claim 1 , wherein at least partial retraction of the device is required for selective opening and closing of at least one of the first and second doors.
7. The system of claim 1 , wherein the 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 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.
8. A vehicle comprising:
a vehicle body having a front end and a rear end, and defining an access opening; and
a system for sealing the access opening, the system having:
a first door arranged to selectively open and close a first portion of the access opening;
a second door arranged to selectively open and close a second portion of the access opening;
a device operatively connected to the first door and configured to be selectively retracted before at least one of the first and second doors is opened and protracted when the first and second doors are closed to thereby seal the first and second portions of the access opening;
a detent operatively connected to the device and configured to latch the device to the first door when the device is protracted and release the device from the first door before the device is retracted;
a controller arranged on the body and configured to selectively retract and protract the device; and
a sensor arranged on the vehicle and configured to detect an impact exceeding a threshold intensity on the body and communicate a signal indicative of the impact to the controller;
wherein the controller retracts and releases the device via the detent upon receipt of the signal from the sensor.
9. The vehicle of claim 8 , wherein the sensor is an accelerometer configured to sense the force of the impact.
10. The vehicle of claim 8 , wherein the signal from the accelerometer is additionally configured to trigger a supplemental inflatable restraint in the vehicle.
11. The vehicle of claim 8 , wherein the sensor is one of a radar, laser, and camera configured to sense an imminent occurrence of the impact.
12. The vehicle of claim 11 , wherein the device is retracted prior to the impact.
13. The vehicle of claim 8 , wherein at least partial retraction of the device is required for selective opening and closing of at least one of the first and second doors.
14. The vehicle of claim 8 , wherein the 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 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.
15. A vehicle comprising:
a body having a front end and a rear end, characterized by an absence of a B-pillar, and defining an access opening on a side of the vehicle; and
a system for sealing the access opening, the system having:
a first door arranged to selectively open and close a first portion of the access opening, wherein the first door is rear-hinged and the first portion of the opening is positioned toward the rear end of the vehicle;
a second door arranged to selectively open and close a second portion of the access opening, wherein the second door is front-hinged and the second portion of the opening is positioned toward the front end of the vehicle;
a device operatively connected to the first door and configured to be selectively retracted before at least one of the first and second doors is opened and protracted when the first and second doors are closed to thereby seal the first and second portions of the access opening;
a detent operatively connected to the device and configured to latch the device to the first door when the device is protracted and release the device from the first door before the device is retracted;
a controller arranged on the body and configured to selectively retract and protract the device; and
a sensor arranged on the vehicle and configured to detect an impact exceeding a threshold intensity on the body and communicate a signal indicative of the impact to the controller;
wherein at least partial refraction of the device is required for selective opening and closing of at least one of the first and second doors; and
wherein the controller retracts and releases the device via the detent upon receipt of the signal from the sensor.
16. The vehicle of claim 15 , wherein the sensor is an accelerometer configured to sense the force of the impact and the signal from the accelerometer is additionally configured to trigger a supplemental inflatable restraint in the vehicle.
