## Abstract

The invention relates to a motor vehicle door lock which is equipped with a body-side lock housing and a hood-or-door-side locking bolt or vice-versa. The invention also relates to a locking and/or opening device. According to the invention, the locking and/or opening device engages on the outer side on the lock housing for the adjustment thereof with respect to a fixed base element in the course of a closing/opening process.

## Claims

### Claim 1

A motor vehicle door lock for a motor vehicle, the motor vehicle including a vehicle frame and a motor vehicle door, the motor vehicle door lock comprising:
a locking bolt on the motor vehicle door;
a latch assembly comprising:
a catch for capturing the locking bolt, the catch being movable into a main ratchet position in which the locking bolt is held;
a first pawl for securing the catch in the main ratchet position;
a frame member enclosing the catch and the first pawl, the frame member having a projection;
a rocker arm pivotally mounted on the vehicle frame;
a second pawl pivotably coupled to the rocker arm and which selectively couples the frame member to the rocker arm by grasping the projection of the frame member;
a drive configured to rotate the rocker arm;
wherein rotation of the rocker arm while the second pawl grasps the projection moves the frame member and the latch assembly relative to the vehicle frame and reduces a gap between the motor vehicle door and the vehicle frame.

### Claim 2 (depends on 1)

The motor vehicle door lock of claim 1, wherein the frame member is pivotally mounted on the vehicle frame.

### Claim 3 (depends on 2)

The motor vehicle door lock of claim 2, wherein the frame member and the rocker arm both pivot about a common axis.

### Claim 4 (depends on 3)

The motor vehicle door lock of claim 3, further comprising a spring that biases the frame member away from the rocker arm.

### Claim 5 (depends on 4)

The motor vehicle door lock of claim 4, wherein the vehicle frame defines a door closed position that corresponds to an inside surface of the motor vehicle door when the motor vehicle door is closed, wherein the rocker arm defines a first position where a portion of the catch is positioned outside the door closed position and a second position where the portion of the catch is positioned inside the door closed position.

### Claim 6 (depends on 3)

The motor vehicle door lock of claim 3, wherein the vehicle frame defines a door closed position that corresponds to an inside surface of the motor vehicle door when the motor vehicle door is closed, wherein the rocker arm defines a first position where a portion of the catch is positioned outside the door closed position and a second position where the portion of the catch is positioned inside the door closed position.

### Claim 7 (depends on 6)

The motor vehicle door lock of claim 6, further comprising a buffer, wherein the rocker arm abuts the buffer in the second position.

### Claim 8 (depends on 2)

The motor vehicle door lock of claim 2, wherein the vehicle frame defines a hood door closed position that corresponds to an inside surface of the motor vehicle door when the motor vehicle door is closed, wherein the rocker arm defines a first position where a portion of the catch is positioned outside the door closed position and a second position where the portion of the catch is positioned inside the door closed position.

### Claim 9 (depends on 8)

The motor vehicle door lock of claim 8, further comprising a buffer, wherein the rocker arm abuts the buffer in the second position.

### Claim 10 (depends on 1)

The motor vehicle door lock of claim 1, further comprising a driving wheel rotatable by the drive about a wheel axis and a pin mounted on the driving wheel offset from the wheel axis, wherein the pin is configured to abut and move the rocker arm.

### Claim 11 (depends on 10)

The motor vehicle door lock of claim 10, wherein the rocker arm has a slot and wherein the pin is positioned within the slot.

### Claim 12 (depends on 11)

The motor vehicle door lock of claim 11, wherein the slot is elliptical in shape.

### Claim 13 (depends on 12)

The motor vehicle door lock of claim 12, wherein the pin acts eccentrically on the rocker arm when the pulley rotates about the pulley axis due to the elliptical shape of the slot.

### Claim 14 (depends on 13)

The motor vehicle door lock of claim 13, wherein the pulley is a driven pulley, driven by a motor.

### Claim 15 (depends on 14)

The motor vehicle door lock of claim 14, wherein the vehicle frame defines a door closed position that corresponds to an inside surface of the motor vehicle door when the hood motor vehicle door is closed, wherein the rocker arm defines a first position where a portion of the catch is positioned outside the door closed position and a second position where the portion of the catch is positioned inside the door closed position.

### Claim 16 (depends on 15)

The motor vehicle door lock of claim 15, further comprising a buffer, wherein the rocker arm abuts the buffer in the second position.

### Claim 17 (depends on 15)

The motor vehicle door lock of claim 15, further comprising a buffer, wherein the rocker arm abuts the buffer in the second position.

### Claim 18 (depends on 1)

The motor vehicle door lock of claim 1, wherein the vehicle frame defines a door closed position that corresponds to an inside surface of the motor vehicle door when the motor vehicle door is closed, wherein the rocker arm defines a first position where a portion of the catch is positioned outside the door closed position and a second position where the portion of the catch is positioned inside the door closed position.
