Abstract

The present invention relates to a motor vehicle having a driver door, a passenger door, and two rear doors. Each of the doors has an internal opening device for opening the corresponding door from the interior of the motor vehicle using an assigned electrical drive, and an external opening device for opening the corresponding door from outside the motor vehicle using an assigned electrical drive. The electrical drives are each provided to lock and unlock the opening device assigned thereto.

Claims

1. A motor vehicle comprising a driver door, a passenger door, and two rear doors, wherein each of the doors has an internal opening device for opening the corresponding door from the interior of the motor vehicle using an assigned electrical drive, and an external opening device for opening the corresponding door from outside the motor vehicle using an assigned electrical drive, and the electrical drives are each provided to lock and unlock the opening device assigned thereto, and the motor vehicle is set up in such a way that, using the electrical drives,

it is operable in a first mode, in which the internal and external opening devices are unlocked

it is operable in a second mode, in which the internal opening devices are unlocked and the external opening devices are locked and

it is operable in a third mode, in which the internal and the external opening devices are locked

and the motor vehicle is additionally operable in a child safety lock mode, in which the internal opening devices of the rear doors are always locked using the electrical drives assigned to the internal opening devices of the rear doors, independently of the first, second, and third modes.

2. The motor vehicle according to claim 1, whose rear doors comprise activatable electrical power-window units in the area of the particular rear doors, which are deactivatable using a switch device in the area of the driver seat, and the motor vehicle is set up in such a way that upon deactivation of the power-window units using the switch device the child safety lock mode is activated.

3. The motor vehicle according to claim 1, which comprises a wireless remote control, using which the motor vehicle may be put into its first, second, and third modes.

4. The motor vehicle according to claim 3, wherein the wireless remote control is additionally implemented in such a way that the child safety lock mode is activatable and/or deactivatable.

5. A door lock for a door of a motor vehicle, comprising:

a locking mechanism having a forked latch, to be situated on the door, and a closing element, which works together with the forked latch and is to be situated on a door frame of the motor vehicle assigned to the door, using which the door is closable in the installed state of the door lock;

an internal opening device, which, in the installed state of the door lock, a mechanical internal actuating device situated on the interior of the door is coupled to the forked latch in a first operating state and is decoupled therefrom in a second operating state, so that, using the internal actuating device, the locking mechanism may be opened in the first operating state and may not be opened in the second operating state;

an external opening device, using which, in the installed state of the door lock, a mechanical external actuating device situated on the exterior of the door is coupled to the forked latch in a first operating state and is decoupled therefrom in a second operating state, so that, using the external actuating device, the locking mechanism may be opened in the first operating state and may not be opened in the second operating state;

a first electrical drive assigned to the internal opening device, using which the internal opening device is switchable between its two operating states independently of the operating state of the external opening device; and

a second electrical drive assigned to the external opening device, using which the external opening device is switchable between its two operating states independently of the operating state of the internal opening device.

6. The door lock according to claim 5, wherein the internal opening device has an internal lever chain and/or the external opening device has an external lever chain.

7. The door lock according to claim 6, wherein the first electrical drive interrupts a connection of the internal lever chain between the internal actuating device and the forked latch in the second operating state.

8. The door lock according to claim 6, wherein the second electrical drive interrupts a connection of the external lever chain between the external actuating device and the forked latch in the second operating state.

9. The door lock according to claim 5, wherein the internal actuating device is an inside door handle situated on the interior of the door and/or the external actuating device is an outside door handle situated on the exterior of the door.

10. (canceled)
