Motor vehicle door lock

摘要

A lock including a catch mechanism made up of a rotary latch and catch for latching the rotary latch. The rotary latch and catch have blocking surfaces for latching purposes. In the latched state, the blocking surface of the rotary latch rests on the blocking surface of the catch, and this prevents the rotary latch from being able to rotate in the direction of the open position. The lock also includes a component with an abutment surface, against which the blocking surface of the rotary latch butts in the open position of the catch mechanism. This abutment prevents the situation where, in the open position, dust can pass onto the blocking surface of the rotary latch. In addition, the abutment reduces the penetration of dust into the catch mechanism. An increase in the opening forces as service life increases is thus avoided.

主权项

1. A lock comprising:
a catch mechanism including a rotary latch moveable between an opened position, an intermediate closed position, and a fully closed position, and a pawl for latching the rotary latch in the intermediate and fully closed positions, wherein the rotary latch includes a first blocking surface and a second blocking surface, wherein the pawl includes a blocking surface that presses against the first blocking surface, latching the rotary latch in the intermediate closed position, and presses against the second blocking surface, latching the rotary latch in the fully closed position, and a damping element having a body located in a plane below the rotary latch and a projection extending into a plane in which the rotary latch lies, wherein the projection has first and second abutment surfaces, wherein one of the first and second blocking surfaces of the rotary latch rests against the first abutment surface in the opened position of the rotary latch, and wherein the second abutment surface abuts against an outer surface of the rotary latch in the fully closed position.
