Abstract

The subject matter of the present invention is a motor-vehicle door lock which is equipped with a locking mechanism, further with an opening drive (3, 4) which acts on the locking mechanism, and also with an operating lever mechanism (6, 7). At least one sensor (8) for checking an operator opening request is further provided. Finally, a safety device (9, 10, 11), which prevents the locking mechanism (3, 4) from opening at least in its “safe” position, is provided. The invention makes provision for an intermediate lever (7) of the operating lever mechanism (6, 7), which intermediate lever mechanically converts the operator opening request, to selectively act on or not act on the sensor (8) which actuates the opening drive (3, 4), depending on the position of the safety device (9, 10, 11).

Claims

1. Motor vehicle door lock with a locking mechanism, further with an opening drive (3, 4) acting on the locking mechanism and an operating lever mechanism (6, 7), as well as at least one sensor (8) for checking an operator opening request and one safety device (9, 10, 11), which prevents the locking mechanism from opening at least in its “

safe”

position, characterized in that an intermediate lever (7) of the operating lever mechanism (6, 7), mechanically converts the operator opening request to selectively act on the sensor (8) or not which actuates the opening drive (3, 4) depending on the position of the safety device (9, 10, 11).

2. Motor vehicle door lock according to claim 1, characterized in that the safety device (9, 10, 11) contains an actuating journal (11), which depending on its position (“

released”

or “

safe”

) acts on the intermediate lever (7) after an operator opening request in order to actuate the sensor (8) or freewheel in relation to the intermediate lever (7).

3. Motor vehicle door lock according to claim 2, characterized in that the safety device (9, 10, 11) operates manually.

4. Motor vehicle door lock according to claim 3, characterized in that the safety device (9, 10, 11) contains a manual actuating element (9) and an actuator (10) supporting the actuating journal (11).

5. Motor vehicle door lock according to claim 4, characterized in that the actuating element (9) is designed as an actuating cam (9) and that the actuator (10) is flexibly connected to the actuating element (9).

6. Motor vehicle door lock according to claim 5, characterized in that the actuator (10) is designed as an actuating slider.

7. Motor vehicle door lock according to claim 6, characterized in that the intermediate lever (7) is designed as a blocking lever (7) interacting with the opening drive (3, 4).

8. Motor vehicle door lock according to claim 7, characterized in that blocking lever (7) in the “

released”

position of the safety device (9, 10, 11) is mechanically coupled to a handle and/or an electric motor drive, whilst in the “

safe”

position of the safety device (9, 10, 11) the handle and or the electric motor drive freewheel in relation to the blocking lever (7).

9. Motor vehicle door lock according to claim 8, characterized in that the safety device (9, 10, 11) is designed as a child lock (9, 10, 11).

10. Motor vehicle door lock according to claim 9, characterized in that the additional at least one locking lever (6) is provided as part of the operating lever mechanism (6, 7).

11. Motor vehicle door lock according to claim 4, characterized in that the actuator (10) is designed as an actuating slider.

12. Motor vehicle door lock according to claim 1, characterized in that the intermediate lever (7) is designed as a blocking lever (7) interacting with the opening drive (3, 4).

13. Motor vehicle door lock according to claim 12, characterized in that blocking lever (7) in the “

released”

position of the safety device (9, 10, 11) is mechanically coupled to a handle and/or an electric motor drive, whilst in the “

safe”

position of the safety device (9, 10, 11) the handle and or the electric motor drive freewheel in relation to the blocking lever (7).

14. Motor vehicle door lock according to claim 13, characterized in that the additional at least one locking lever (6) is provided as part of the operating lever mechanism (6, 7).

15. Motor vehicle door lock according to claim 2, characterized in that the intermediate lever (7) is designed as a blocking lever (7) interacting with the opening drive (3, 4).

16. Motor vehicle door lock according to claim 15, characterized in that blocking lever (7) in the “

released”

position of the safety device (9, 10, 11) is mechanically coupled to a handle and/or an electric motor drive, whilst in the “

safe”

position of the safety device (9, 10, 11) the handle and or the electric motor drive freewheel in relation to the blocking lever (7).

17. Motor vehicle door lock according to claim 5, characterized in that the intermediate lever (7) is designed as a blocking lever (7) interacting with the opening drive (3, 4).

18. Motor vehicle door lock according to claim 17, characterized in that blocking lever (7) in the “

released”

position of the safety device (9, 10, 11) is mechanically coupled to a handle and/or an electric motor drive, whilst in the “

safe”

position of the safety device (9, 10, 11) the handle and or the electric motor drive freewheel in relation to the blocking lever (7).

19. Motor vehicle door lock according to claim 1, characterized in that the safety device (9, 10, 11) is designed as a child lock (9, 10, 11).

20. Motor vehicle door lock according to claim 1, characterized in that the additional at least one locking lever (6) is provided as part of the operating lever mechanism (6, 7).
