Abstract

In one embodiment, an automotive vehicle is disclosed having a vehicle body with a first pillar, a second pillar, a roof member and a floor member defining a door opening therebetween. A lateral side entry door is pivotally connected to the vehicle body for enclosing the door opening. The side entry door moves along an operating path having a closed position and an open position. The vehicle has a motor and a lead screw mounted in the side entry door and connected to the motor to be driven by the motor. The vehicle has a link connected to the lead screw and connected to the vehicle body adjacent to the door opening. The motor drives the lead screw to translate the link to open and close the side entry door.

Claims

1. A passenger vehicle comprising:

a vehicle body having a first pillar, a second pillar, a roof member and a floor member defining a door opening therebetween;

a lateral side entry door pivotally connected to the vehicle body for enclosing the door opening, the side entry door moving along an operating path and having a closed position and an open position;

a motor oriented in the side entry door;

a lead screw mounted in the side entry door and connected to the motor to be driven by the motor; and

a link connected to the lead screw and connected to the vehicle body adjacent to the door opening;

wherein the motor drives the lead screw to translate the link to open and close the side entry door.

2. The passenger vehicle of claim 1 further comprising an electric clutch provided between the motor and the lead screw to allow manual translation of the side entry door along the operating path when disengaged and to couple the motor and the lead screw so that the motor drives the lead screw when engaged.

3. The passenger vehicle of claim 1 further comprising:

a lock mechanism provided within the side entry door for cooperating with the vehicle body to lock the side entry door in a closed position; and

a clutch provided between the motor and the lock mechanism to disengage the motor from the lock mechanism to allow manual locking and unlocking of the lock mechanism and to engage the motor and the lock mechanism so that the motor drives the lock mechanism to lock or unlock.

4. The passenger vehicle of claim 1 further comprising a translatable window mounted within the side entry door, wherein operation of the motor drives the translatable window to open and close the window.

5. The passenger vehicle of claim 1 further comprising a latch assembly provided within the vehicle body and the side entry door to secure the side entry door to the vehicle body in the closed position.

6. The passenger vehicle of claim 5 wherein the latch assembly is controlled by computer software to lock the side entry door in the closed position.

7. The passenger vehicle of claim 1 wherein the link is further defined as a check strap to maintain the side entry door in an intermediate position between the open position and the closed position.

8. The passenger vehicle of claim 7 wherein the check strap further comprises at least one detent provided therein to cooperate with a pair of rollers for manual translation of the side entry door.

9. The passenger vehicle of claim 1 further comprising an obstacle detection system in communication with the motor for determining when an object is in the path of the side entry door to stop translation of the motor.

10. The passenger vehicle of claim 9 further comprising a pinch protection member provided between the side entry door and the door opening in communication with the obstacle detection system.

11. The passenger vehicle of claim 9 wherein the obstacle detection system further comprises a sensor provided proximate the side entry door to provide an output signal to one of the motor and an electric clutch connected to the motor to stop translation of the side entry door when an object is detected in the operating path of the side entry door.

12. The passenger vehicle of claim 11 wherein the sensor provides the output signal to the motor.

13. The passenger vehicle of claim 11 wherein the sensor provides the output signal to the electric clutch.

14. The passenger vehicle of claim 11 wherein the sensor further comprises at least one ultrasonic sensor.

15. The automotive vehicle of claim 11 wherein the sensor further comprises at least one radar sensor.

16. The passenger vehicle of claim 11 further comprising a rub strip provided on an outer portion of the side entry door, wherein the sensor is mounted in the rub strip of the side entry door to provide an output signal to stop translation of the side entry door when an object is detected in the operating path of the side entry door as the side entry door travels from the closed position to the open position.

17. The passenger vehicle of claim 11 further comprising a handle provided on an outer portion of the side entry door to allow manual translation of the side entry door, wherein the sensor is provided in the handle of the side entry door to provide an output signal to stop translation of the side entry door when an object is detected in the operating path of the side entry door as the side entry door travels from the closed position to the open position.

18. The passenger vehicle of claim 11 wherein the sensor is provided in one of the first and second pillars of the vehicle body such that the sensor provides an output signal to stop translation of the side entry door when an object is detected in the operating path of the side entry door as the side entry door travels from the open position to the closed position.

19. An automotive vehicle comprising:

a vehicle body having a first pillar, a second pillar, a roof member and a floor member defining a door opening therebetween;

a side entry door pivotally connected to the vehicle body for enclosing the door opening, the side entry door moving along an operating path and having a closed position and an open position;

a motor oriented in the side entry door;

a transmission mounted on the side entry door and connected to the motor to be driven by the motor; and

a check strap mounted on the vehicle body and pivotally connected to the transmission, the check strap having at least one detent provided therein to cooperate with at least one roller for manual translation of the side entry door, the check strap maintaining the side entry door in an intermediate position between the open position and the closed position;

wherein the motor drives the lead screw to translate the check strap to open and close the side entry door.

20. A power door assembly for a vehicle, comprising:

a side entry door having a first hinge portion to be pivotally connected to a vehicle body for movement along an operating path for opening the side entry door from the door opening and closing the side entry door to the door opening;

a motor oriented in the side entry door;

a lead screw mounted in the side entry door and connected to the motor to be driven by the motor; and

a link connected to the lead screw and adapted to be connected to the vehicle body adjacent to the door opening;

wherein the motor drives the lead screw to translate the link to open and close the side entry door.
