Abstract

The invention relates to a lock for a motor vehicle with a locking mechanism including a catch and a pawl. The object of the invention is to simplify the locking of a lock of the type mentioned above. To achieve the object of the invention, a catch of the claimed lock comprises a stop projecting upwards, e.g., in the form of a pin extending from the catch. Furthermore, a bracket is provided, which can be moved against the stop by means of a motor such that the catch is moved in this way from the first position and into the primary position. It is thus possible to move from the first position to the primary position in a motorized manner, which makes it easier to close the vehicle door.

Claims

1. A lock for a motor vehicle with a locking mechanism comprising a catch (4) and a pawl (6), wherein said catch can be locked in a first position and a primary position, wherein said catch further comprises a protruding stop (18) for a bracket (32), wherein said catch can be rotated from said first position into said primary position by moving said bracket by means of a motor drive, and wherein said stop (18) for said bracket (32) functions simultaneously as a stop for said pawl.

2. The lock of claim 1, wherein the lock comprises a primary-position pawl (6) and a first-position pawl (13), and said stop (18) is a locking means for locking said catch with said first-position pawl (13).

3. The lock of claim 2, wherein said bracket (32) is disposed above said first-position pawl (13) as seen from a housing wall (1) of the lock, on which housing wall (1) said catch (4) is pivotally mounted.

4. The lock of claim 3, further comprising a guide (30, 33) which controls a movement of said bracket (32) relative to said first-position pawl (13).

5. The lock of claim 1, wherein said bracket (32) is initially movable in a straight line starting from a starting position and is subsequently movable on a curve corresponding to a movement of said catch (4) into a final position.

6. The lock of claim 2, wherein said bracket is controlled via a slot (33) into which a first pin (30) of said first-position pawl (13) extends.

7. The lock of claim 2, wherein said bracket comprises a second pin (34) that projects upwards, which second pin (34) extends into a hole of a first lever (37), and which second pin (34) can be moved by a motor.

8. The lock of claim 7, wherein a motor actuates a long, second lever, which is longer compared to said first lever (37) comprising a hole into which said second pin (34) extends.

9. The lock of claim 7, further comprising stops for said second pin (34), between which stops said second pin (34) can be moved back and forth.

10. The lock of claim 1, wherein said bracket (32) has a distance to its stop (18) when said catch (4) is locked in said first position.

11. The lock of claim 1, wherein said bracket (32) can be moved from its initial position to its final position by means of a cable (39).

12. The lock of claim 1, wherein said bracket (32) can be moved from its initial position to its final position by a biasing force.

13. The lock of claim 1, wherein said bracket (32) can be moved from its initial position to its final position by a first lever (37) which is biased.

14. The lock of claim 2 comprising control means, wherein said control means function to move said bracket (32) in the direction toward its final position by means of a motor, when said first-position pawl (13) is in its locked position and when said primary-position pawl (6) is not in its locked position.

15. The lock of claim 14, wherein said control means are micro switches (40) for determining positions of said pawls (6, 13).

16. The lock of claim 15, wherein said micro switches (40) abut shoe-shaped lever arms of said pawls (6, 13) in certain positions of said pawls (6, 13).
