Claims

1. A motor vehicle lock comprising: a locking mechanism with a rotary latch and at least one pawl, wherein a rotary movement of the rotary latch is blocked in at least one latching position by the pawl; a lock case; and a bearing point accommodated on the lock case for at least one component of the locking mechanism, wherein the motor vehicle lock is mounted on the motor vehicle by the lock case, and wherein the motor vehicle lock also is mounted on the motor vehicle by the bearing point of the at least one component of the locking mechanism.

2. The motor vehicle lock according to claim 1, wherein the bearing point has a thread.

3. The motor vehicle lock according to claim 1, wherein the bearing point is a separate component from the lock case.

4. The motor vehicle lock according to claim 1, wherein the bearing point is non-detachably connected to the lock case.

5. The motor vehicle lock according to claim 1, wherein the bearing point is a threaded bushing that provides a sliding surface for the component of the locking mechanism, and wherein the component of the locking mechanism is mounted directly on the threaded bushing.

6. The motor vehicle lock according to claim 1, further comprising a reinforcement plate, and the bearing point is accommodated in the reinforcement plate.

7. The motor vehicle lock according to claim 6, wherein the bearing point is non-detachably connected to the reinforcement plate.

8. The motor vehicle lock according to claim 6, wherein the reinforcement plate is connected to the lock case via at least one further threaded bushing.

9. The motor vehicle lock according to claim 1, wherein the lock case has a thickness of 2 mm to 3 mm, and the reinforcement plate has a thickness of 1.5 mm to 2.5.

10. The motor vehicle lock according to claim 1, wherein a metric thread having a size of 6 mm to 12 mm is contained in the bearing point.

11. The motor vehicle lock according to claim 1, wherein the lock case has a thickness of 2.5 mm, and the reinforcement plate has a thickness of 2 mm.

12. The motor vehicle lock according to claim 1, wherein a metric thread having a size of 8 mm is contained in the bearing point.

13. The motor vehicle lock according to claim 1, wherein a metric thread having a size of 10 mm is contained in the bearing point.

14. The motor vehicle lock according to claim 1, wherein the bearing point has a differing diameter external geometry for a one-sided insertion into the lock case, and an edge of the bearing point is flanged against the lock case to form a collar.

15. The motor vehicle lock according to claim 1, wherein the bearing point includes a steel material.

16. The motor vehicle lock according to claim 1, wherein the bearing point is a bearing point for the rotary latch.

17. The motor vehicle lock according to claim 5, wherein the threaded bushing has a middle part and a shoulder at ends of the threaded bushing, and in the middle part the threaded bushing has a larger diameter and a greater wall thickness relative to the ends.

Description

[0029] In the figures:

[0030] FIG. 1 shows a three-dimensional view of a motor vehicle lock designed according to the invention, with a section through a bearing point, wherein the bearing point acts as a bearing bushing for a rotary latch, and

[0031] FIG. 2 shows a plan view of the locking mechanism according to FIG. 1, wherein only the components of the motor vehicle lock that are relevant for explaining the invention are shown.

[0032] The threaded bushing 15 shown in FIG. 1 has a shoulder 22 which results from a larger diameter of the threaded bushing 15. The bearing point 15 is consequently provided with different diameters. In the interior of the bearing point 15, a thread is shown which serves in this exemplary embodiment to accommodate a metric screw with a thread M10. Furthermore, a collar 24 can be seen in FIG. 1, wherein the collar is formed on both sides of the bearing point 15. By forming the collar 24, the bearing point 15, 16 can be non-detachably connected to the lock case 3 and also to the reinforcement plate 4. A running surface 25 for the rotary latch 6 is formed on an outer surface of the bearing point 15. The bearing point 15 therefore serves as a fastening means for the motor vehicle lock, for stabilizing the lock by the connection of the lock case 3 and the reinforcement plate 4, and additionally as a bearing bushing 15 for the locking mechanism part 6.

[0033] As can be seen from the exemplary embodiment, the threaded bushing 15, 16 can serve exclusively for stabilizing the overall lock and for fastening the motor vehicle lock in the motor vehicle, but the threaded bushing can also form a bearing point 15 for a locking mechanism part. It can be seen in this exemplary embodiment that the reinforcement plate 4 is held by the threaded sleeves 15, 16 and the shaft 19 in the motor vehicle lock 1, and can serve overall for stabilizing the motor vehicle lock 1.

[0034] FIG. 2 shows a plan view of the locking mechanism 5 of the motor vehicle lock 1. It can be seen that the threaded sleeves 15, 16 serve on the one hand for fastening the motor vehicle lock 1 to the motor vehicle, and, on the other, the threaded bushing 15 acts as a bearing point 15 for the rotary latch. This can in particular produce a precise alignment of the rotary latch 6 with respect to a lock holder 26. The locking mechanism 5 is shown in an open position, wherein the lock holder 26 transfers the rotary latch 6 to a latching position by a relative movement between the motor vehicle lock 1 and the lock holder 26 so that the latching element 27 engages with a latching surface 28 on the pawl 7. Due to the multi-functionality of the bearing point 15, the structure of the motor vehicle lock 1 can be significantly reduced, and high tolerance specifications can be maintained reliably and with long-term stability.
