Motor vehicle door latch

1. A motor vehicle door latch comprising:

a locking mechanism including a catch and a pawl,

a spindle drive with a motor, a spindle operable by the motor, and a spindle nut slidably movable on the spindle, and

a closure lever operatively mounted to the spindle nut, the closure lever being used as a closure/opening lever to open and close the locking mechanism,

wherein the spindle nut is movable between a neutral position toward a closing position in which movement of the spindle nut enables the closure/opening lever to impinge the catch in a closed direction and close the locking mechanism, or toward an opening position in which movement of the spindle nut enables the closure/opening lever to impinge the pawl in an opening direction and open the locking mechanism,

wherein the closure/opening lever includes a movable member that interacts with a static conducting element to impinge the pawl or the catch.

2. The motor vehicle door latch according to claim 1 , wherein the closure/opening lever includes a pivoting lever that is connected to and pivotable about a common axis of the catch.

3. The motor vehicle door latch according to claim 2 , wherein the pivoting lever is connected to the spindle nut by a rotating joint at one end of the pivoting lever and the pivoting lever is connected with the catch at another end of the closure/opening lever.

4. The motor vehicle door latch according to claim 2 , wherein the movable member of the closure/opening lever is a stop element pivotably located on the pivoting lever which, dependent on an actuating direction of the spindle drive either interacts with the pawl or a stop on the catch.

5. The motor vehicle door latch according to claim 4 , wherein the stop element is pivoted starting from the neutral position of the spindle drive with the aid of the static conducting element according to the actuating direction of the spindle drive either in a direction toward the pawl or in a direction toward the catch around an axis of the stop element formed on the closure/opening lever.

6. The motor vehicle door latch according to claim 1 , wherein the neutral position of the spindle drive is only assumed in a spring-assisted manner.

7. The motor vehicle door latch according to claim 6 , wherein the spindle drive is includes at least one opening/resetting spring to assume the neutral position following an opening process of the locking mechanism.

8. The motor vehicle door latch according to claim 7 , wherein the opening/resetting spring is arranged between a stop on a motor side of the spindle drive and a stop on a spindle nut side of the spindle drive.

9. The motor vehicle door latch according to claim 7 further comprising a closure/resetting spring to assume the neutral position after a closure process of the locking mechanism.

10. The motor vehicle door latch according to claim 9 , wherein the opening/resetting spring has a larger spring constant than the closure/resetting spring which is at least two to three times as large.

11. The motor vehicle door latch according to claim 5 further comprising a housing, wherein the static conducting element is fixed to the housing.

12. The motor vehicle door latch according to claim 11 , wherein the static conducting element is a bolt.

13. The motor vehicle door latch according to claim 12 , wherein a contour of the stop element slides along the bolt when the stop element is pivoted.

14. The motor vehicle door latch according to claim 4 , wherein the stop element has a first stop surface that is configured to directly contact the pawl during an opening process and a second stop surface that is configured to directly contact the catch during a closing process.

15. The motor vehicle door latch according to claim 3 , wherein the pivoting lever is a flat lever having a width that extends in an actuating direction of the spindle drive.
