Definitions

  • the invention relates ⁇ to a KraffGermantuerver gleich, with at least one locking mechanism consisting essentially of catch and Sperrklioke, and with at least one housing fixed stop for the locking mechanism, wherein the stop acts with a ⁇ usvölbung plastic on the rotary latch and / or the pawlitz-.
  • the Drehfalie Ober a buffer pocket, which is assigned in Sc iieSraum the Drehfalie the previously mentioned buffer stop for AufpraSIminderung.
  • the buffer bag is realized as a slot in a Kunststoffummanteiung the Drehfalie.
  • the buffer stop cooperates with a bulge, which is arranged in the main latch of the rotary latch between the buffer pocket and the buffer stop.
  • the invention is based on the technical problem of further developing such a vehicle door latch such that the damping of noise during the closing operation is improved even further compared with the prior art and, in particular, preclusive operations in the locking mechanism are avoided or at least suppressed.
  • the invention proposes in a generic raftchristmver gleich that the ⁇ uswölbung and the stop are made of different or different hard plastics. That is, both the ⁇ uswölbun 5 and the stopper are each made of plastic.
  • different plastics are used according to the invention, namely those with different elasticity or hardness, In fact, it has proven to be beneficial in this context, when the ⁇ uswöibung is formed as a soft component and the stopper as a hard component.
  • the hard component of the resin for the stop typically comprises a S 'hore D hardness of 40 to 80 and preferably from 50 to 65 in this context.
  • Shore ⁇ hardness in the case of plastics is determined in such a way that a test body which is usually designed as a steel pin is pressed by spring force onto the corresponding plastic or its surface.
  • the method for determining the Shore D hardness generally works with a spring ratio of 0.55.
  • the invention recommends the use of plastics such as those made of polyester (PES) or polycarbonate (PC).
  • PET polyester
  • PC polycarbonate
  • a possible antiviral is offered under the brand name Hytrei® and goes back to the company DuPont.
  • the Shore D hardness of these materials is in the range of 50 to 65.
  • this has a Shore A hardness of less than 80 and in particular less than 70.
  • the Shore A hardness is below 60.
  • elastomers such as ethylene-acrylate rubber (EA) or fluorosilicone rubber (FQ).
  • EA ethylene-acrylate rubber
  • FQ fluorosilicone rubber
  • other elastomers can be used, as long as their Shore ⁇ hardness is regularly below 80 and in particular less than 70.
  • the particularly "soft" design of the soft component or the buckle contributes to the fact that the buckle in question in general interacts with the stop in such a way that the oil sinks into a recess on or in the stop. In fact, the stop regularly has such a recess for the bulge.
  • the bulge advantageously designed as a soft component is designed in the manner of a brake pad, which is received in the recess of the stop as a hard component and snuggles into the recess.
  • Characterized the locking mechanism is not only slowed down when immersing the bulge in the recess, but also held at the same time, so that the previously described bouncing or associated ⁇ bouncing processes are not or practically no longer occur.
  • the interaction between the regularly designed as a soft component AuswöSbung on the one hand and trained as a hard component stop on the other hand does not nu for the fact that minor relative movements between the locking mechanism and the stop are allowed and compensated. But the ratchet remains generally in its closed position by the interaction between the bulge and the stop or the Ausaussbung receiving recess.
  • the bulge is provided on the Drehfalie.
  • it is usually in the main position of the Drehfalie to the described interaction between the bulge and the stop or the stop associated with the recess, so that the previously described Preüen not or practically can not occur.

  • the Drehfaile or Sperrkiinke on the one hand and the bulge on the other hand can be made separately and made of different materials. That's the case regularly.
  • the catch and the pawl are typically designed as etailmaschine and in particular Stahlstanzteiie, whereas the ⁇ uswöibung is designed as a plastic part.
  • the buckle is designed as a plastic nose.
  • a locking connection, a screw or other releasable connections are conceivable for coupling on the one hand the bulge and on the other hand, the rotary latch or Sperrkiinke.
  • the bulge and the Drehfaile or Sperrkiinke are adhesively connected. But it can also be proceeded so that the bulge is formed integrally with the Drehfaile and / or the pawl.
  • the Drehfaile respectively the pawl may be provided with a plastic Ummanteiung, which not only covers the Drehsociie or Sperrkiinke, but in addition to the expression of trained on the Drehfaile or Sperrkiinke ⁇ uswöibung serves.
  • the protrusion typically projects in front of a circumference of the rotary latch.
  • the Stop including the associated recess is typically formed in or on a housing of the motor vehicle door lock, thus designed fixed to the housing, mostly used here on a housing cover, which is anyway made of a (hard) plastic, for example polyester or polycarbonate polycarbonate, the previously described suitable plastics
  • the stop can be integrally formed with the housing or regularly a housing cover.
  • the invention is based on the recognition that the catch and the pawl or the locking mechanism are mounted in a metallic lock case, which is covered by means of the housing or the addressed housing cover.
  • the housing cover in question generally extends above the lock case.
  • the stop can be easily defined on the housing cover: be and projects in this way into the lock box in order to interact with the bulge on the rotary latch respectively the pawl can.
  • the housing or the housing cover is usually produced in the course of a Kunststoffepntegussvorgahges.
  • the subject matter of the invention is also a method for producing a motor vehicle closure, in which the bulge on the one hand and the stop on the other hand are made of the different plastics or different hard plastics, in each case the described jamming of the rotary latch or locking belt regularly takes place in the Main locking position of the locking mechanism that the locking mechanism is fixed.
