Abstract

A door system is provided for a passenger vehicle having at least two seat rows. The door system includes a front side door of a corresponding vehicle side, which can be brought into an open position from a closed position in order to take a seat in the rear seat row or to leave the rear seat row. In order to create a door system by which easier and more comfortable closing of the front side door is enabled, the front side door can be moved from the open position into the closed position by a door drive.

Claims

1. A door system for a passenger vehicle having at least two rows of seats, the door system comprising:

a front side door of a corresponding vehicle side, wherein

the front side door is brought into an open position from a closed position to allow for entering or exiting from the rear seat row, and

a door drive operatively configured to move the front side door from the open position into the closed position.

2. The door system according to claim 1, further comprising:

a rear side door of the door system, wherein

the front side door and the rear side door are attached on two opposite sides of a door portal and are mounted to open in opposite directions, and

the front side door and the rear side door border each other at a butt joint in their respective closed positions, in which case the front side door covers the rear side door.

3. The door system according to claim 1, wherein

the door drive is additionally configured as a door brake by which the front side door is to be braked during opening thereof and held in the respective open position.

4. The door system according to claim 2, wherein

the door drive is additionally configured as a door brake by which the front side door is to be braked during opening thereof and held in the respective open position.

5. The door system according to claim 1, further comprising:

an activating element operable by a driver of the passenger vehicle, wherein the activating element activates the door drive.

6. The door system according to claim 5, wherein

the activating element is a central closing button of a closing mechanism of the passenger vehicle.

7. The door system according to claim 2, further comprising:

a closing mechanism provided with respective door locks, by which the corresponding side doors are held in the closed position and which are to be unlocked by a respective interior activating element, wherein

after an activation of an enable function of the closing mechanism, a door lock of the front side door is to be unlocked by an activating element different from the front side door activating element.

8. The door system according to claim 7, wherein

after the activating of the enable function of the closing mechanism, the door lock of the front side door is to be unlocked by the activating element of the door lock of the rear side door.

9. The door system according to claim 7, wherein

after the activating of the enable function of the closing mechanism, the door lock of the front side door is to be unlocked by a first movement of the activating element of the door lock of the rear side door, and then the door lock of the rear side door is to be unlocked by a further movement of said activating element.

10. A method of operating a door system for a passenger vehicle having at least two rows of seats, the method comprising the acts of:

providing a front side door on a corresponding vehicle side, the front side door being openable into an open position from a closed position to allow entry or exiting from the rear seat row; and

moving the front side door from the open position into the closed position via a door drive.

11. A method according to claim 10, wherein a rear side door is provided, and further wherein

the front side door and the rear side door are attached on two opposite sides of a door portal and are mounted to open in opposite directions, and

the front side door and the rear side door border each other at a butt joint in their respective closed positions, in which case the front side door covers the rear side door.

12. The method according to claim 11, wherein

the door drive is additionally configured as a door brake by which the front side door is to be braked during opening thereof and held in the respective open position.

13. The method according to claim 12, further comprising the act of:

activating, via an activating element operable by a driver, the door drive in order to move the front side door from the open position into the closed position.

14. The method according to claim 13, wherein

the activating element is a central closing button of a closing mechanism of the passenger vehicle.

15. The method according to claim 14, further comprising the acts of:

providing a closing mechanism with respective door locks, by which the corresponding side doors are held in the closed position and which are to be unlocked by a respective interior activating element, wherein

after an activation of an enable function of the closing mechanism, a door lock of the front side door is to be unlocked by an activating element different from the front side door activating element.

16. The method according to claim 15, wherein

after the activating of the enable function of the closing mechanism, the door lock of the front side door is to be unlocked by the activating element of the door lock of the rear side door.

17. The method according to claim 15, wherein

after the activating of the enable function of the closing mechanism, the door lock of the front side door is to be unlocked by a first movement of the activating element of the door lock of the rear side door, and then the door lock of the rear side door is to be unlocked by a further movement of said activating element.
