Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism comprising at least two locking components such as a rotary latch and pawl, wherein at least one locking component has at least one metallic base body, a sheath made of a high-strength plastic and a flexible damping element as component elements.
  • the rotary latch or the pawl or even both aforementioned ratchet members may have the three-component structure described above. This consists of at least the metallic body, the sheath of a high-strength plastic and finally the flexible damping element together.
  • the three components are referred to as respective component elements, that is, as elements of the correspondingly designed Gesperrebauteils.
  • the known damping element comprises a flexible reversible sheath containing a gel.
  • a gel is understood as meaning a finely dispersed system comprising at least one solid and one liquid phase.
  • a pawl is provided, which is equipped with a sheath made of a hard elastic plastic.
  • an elongated cavity is provided, in which an elastic damping material is introduced.
  • This may be, for example, a soft plastic or foam.
  • the manufacture is such that the pawl is produced in a two-component injection molding process in which the sheath and either the damping material introduced into the cavity or the damping layer forming a cavity are simultaneously brought into the respective position. That is, the individual components or component elements of the known Gesperrebauteils are in turn connected adhesively. This again results in complex production steps.
  • the metallic base body provides the required mechanical stability and also the storage of the relevant Gesperrebauteils in a (also metallic) lock case. Indeed takes the metallic body on all forces occurring in this context, especially in an accident.
  • the sheath made of high-strength plastic has primarily to provide the function for damping the operation of the motor vehicle door lock and to allow the lowest possible operation. It prevents, for example, a mutual sanding of the metallic base body and the metallic lock case.
  • the flexible damping element ensures to cushion a mutual impact between the ratchet components and the clashing sounds and to provide a smooth deceleration.
  • the described three components or component elements of the respective Gesperrebauteils nowadays has a special importance, which still grows by the fact that motor vehicles are typically inside and lower and quieter, so that previously unnoticed noises increasingly come to the fore.
  • DE 10 2008 034 640 A1 teaches a jacketed Gesperrebauteil for a motor vehicle door lock, in which a detachable connection between the metallic base body and the jacket element is propagated.
  • the releasable connection can be designed as a clip connection.
  • the known Gesperrebauteil engages only on two components, namely the metallic body and the sheath of the plastic high strength back, so is compared to the generic doctrine is a step back.
  • the invention aims to provide a total remedy.
  • the invention is based on the technical problem of further developing such a motor vehicle door lock so that a simple construction and a cost-effective production are observed.
  • a generic motor vehicle door lock in the context of the invention is characterized in that the component elements or components of the Gesperrebauteils are each coupled by a releasable plug / push connection.
  • the individual component elements or components of the considered ratchet component are not adhesively coupled to one another. Rather, it has been found that at this point releasable connectors are sufficient. Alternatively or additionally, however, it is also possible to work with detachable thrust connections and, in particular, detachable slide-in connections.
  • the production of the Gesperrebauteils can be easily integrated into the mass production of motor vehicle door locks and can be used on conventional manufacturing methods. In particular, expensive injection molding, adhesive bonding, etc. are not required.
  • the appropriately constructed Gesperrebauteil is directly available for further processing.
  • the locking component in question may be the catch or the pawl or the catch and the pawl.
  • the correspondingly constructed ratchet component is designed as a pawl.
  • the locking mechanism is composed of at least one rotary latch and the pawl constructed from the described three components or three component elements.
  • the sheath of the high-strength plastic typically means a prefabricated component made of a thermoplastic such as, for example, polypropylene (PP), polyethylene (PE), polyoxymethylene (POM), etc. Particularly preferred at this point is polyester (PES) particularly favorable and resistant to wear.
  • the flexible damping element is a rubber-elastic element, as a rule a rubber-elastic plastic such as natural rubber (NR), styrene-butadiene rubber (EPDM), etc. ..
  • the flexible damping element is also designed as a prefabricated component.
  • the metallic base body can be inserted into the sheath.
  • the sheath may be equipped with a pocket for receiving the metallic base body.
  • the flexible damping element is coupled to the sheath via a plug connection.
  • the flexible damping element is inserted in the casing.
  • the flexible damping element is equipped with locking knobs.
  • the locking knobs engage in recesses of the casing in the installed state. Since the flexible damping element is made of a rubber-elastic plastic, the locking connection described between one hand, the rubber-elastic and flexible damping element and on the other hand, the rigid sheath made of high-strength plastic can be realized easily.
  • the flexible damping element is regularly formed as an extension of the metallic base body.
  • the flexible damping element provides as it were for an extension of the metallic base body in the direction of a stop for the Gesperrebauteil respectively the pawl in the example.
  • the metallic base body does not touch the stop in question, which is connected to the lock case. Rather, it comes here to a mechanical interaction between the flexible damping element as an extension of the metallic base body and the stop in question.
  • This has the consequence that a direction of the stop directed movement of the pawl is attenuated by the flexible damping element of the rubber-elastic plastic particularly effective.
  • the pawl is thus effectively braked when starting against the stop by means of the flexible damping element of the rubber-elastic plastic. Any sounds caused by a hard hit are not observed.
  • the sheath can accommodate both the metallic base body in its interior and the flexible damping element, it advantageously has two pockets.
  • the one bag provides for the inclusion of the body, while the other pocket receives the damping element in its interior.
