Abstract
A door lock, in particular a motor vehicle door lock, which is equipped with a locking mechanism that substantially consists of a rotary latch and at least one pawl. Each of the two locking mechanism parts is rotatably supported on a base about a respective axis. For this purpose, a bearing surface of each locking mechanism part slides along a fixed support body. According to the invention, the support body is provided with an open bearing trough for receiving the bearing surface.
Claims18
A door lock for a motor vehicle door, the door lock comprising:
- a locking mechanism including a rotary latch and a pawl, wherein each of the rotary latch and the pawl is rotatably supported on a base about a respective axis;
- and
- a fixed support body having a resistance radius from a center of gravity of the support body to a periphery of the support body associated with a modulus of resistance and a bearing trough formed in the periphery, wherein the pawl has a bearing surface with a bearing radius, wherein the pawl engages the bearing trough via the bearing surface, and wherein the resistance radius is larger than the bearing radius,
- wherein at least one guide surface is provided,
- wherein the at least one guide surface is provided on a casing of the pawl, and wherein the at least one guide surface is configured to engage at least one corresponding mating guide surface to ensure that the bearing surface remains in contact with the bearing trough.
A door lock for a motor vehicle door, the door lock comprising:
