Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism accommodated in a housing, and with a reinforcing element for the locking mechanism.
  • the locking mechanism is usually composed of a rotary latch and a pawl and interacts with a locking bolt, as is generally known and is described, for example, in the generic state of the art according to DE 199 34 877 AI.
  • a reinforcement element in the form of a closed housing for receiving the locking mechanism is realized.
  • reinforcement elements are known from practice in the form of reinforcement plates which are connected to the housing by rivets.
  • the housing can be a lock case or a lock plate, which is made of metal and in which the locking mechanism is stored.
  • the reinforcement element is now riveted to the lock case or lock plate in question - as described. This is complex in terms of production technology.
  • the locking mechanism is exposed to increased forces, particularly in the event of a side impact, for example when an outer door panel is pressed against the housing and possibly causes deformation here. In extreme cases, this can lead to a blockage of the locking mechanism, so that an associated motor vehicle door can no longer be opened.
  • the known embodiments allow improvements with regard to crash safety.
  • the invention is based on the technical problem of developing a motor vehicle door lock of the design described at the outset in such a way that, with simple and inexpensive production, the crash safety is improved in particular in the event of a side impact.
  • a generic motor vehicle door lock is characterized according to the invention in that the reinforcing element has a lateral protrusion with respect to the housing, which extends essentially in the opposite direction compared to a possible direction of impact.
  • the protrusion extends essentially in the opposite direction compared to a possible side impact direction. This is regularly the vehicle's transverse direction or Y direction. In principle, however, the motor vehicle door lock described can also be used in a tailgate. Then you will arrange the protrusion so that it is arranged in the opposite direction compared to a possible rear impact direction. The protrusion will then essentially extend in the X direction, ie in the vehicle longitudinal direction.
  • the overhang ensures that deformations of the respective motor vehicle door (driver's door, passenger door, side door or tailgate) or the door outer panel caused in the event of an impact are not introduced directly into the housing or the lock case.
  • the reinforcing element has the relevant overhang in relation to the housing, a deformed outer door panel comes to rest against the respective reinforcing element. Impact forces are therefore introduced into the reinforcing element, which may deform. In this way, however, such deformations are kept away from the lock case or the housing, so that the storage of the locking mechanism is not or only barely impaired.
  • the functionality of the rotary latch and pawl is still there, so that a motor vehicle door can still be opened even after a side or rear impact, which was often not possible until now.
  • the reinforcement element is a reinforcement plate which fixes the axes of the rotary latch and the pawl, the reinforcement element being arranged essentially coplanar in comparison to a base plate of the housing or lock case.
  • the reinforcing element and base plate run essentially parallel to one another.
  • the reinforcement element can be connected to the housing or lock case by means of a snap-in or plug connection.
  • the rotary latch and the pawl or their axes are also fixed.
  • the connection techniques described, namely the snap-in connection, plug-in connection, adhesive connection, etc., are clearly superior to the rivets previously pursued at this point in that they can be implemented easily and quickly, thus resulting in cost savings.
  • the reinforcing element usually has recesses for fastening webs projecting from the housing.
  • the fastening webs thus pass through the recesses, spring tongues arranged in the region of the recesses engaging in recesses in the fastening webs.
  • the spring tongues snap into the recesses in the fastening webs, so that the reinforcement element is held captively on the housing or the lock case.
  • the reinforcing element may be arched with a recess in the area of an inlet mouth and a back protruding beyond the housing. The supernatant is part of this back or coincides with it.
  • the reinforcement element has two fastening legs for the axes of the rotary latch and the pawl. The two fastening legs thus form, on the one hand, a rotary latch fastening leg and, on the other hand, a pawl fastening leg and have the openings already mentioned, which are penetrated by the axes standing on the base plate.
  • the reinforcing element may additionally have one or more additional receptacles for at least one lever.
  • This lever is preferably the outside actuation lever, which is connected to an outside door handle and provides for opening of the locking mechanism during outside operations.
  • the mounting of the external actuation lever on the reinforcement element not only creates space in the interior of the housing or lock case, but at the same time further increases crash safety. This is because the external actuation lever is decoupled from the housing or lock case by its attachment to the reinforcing element, so that its deformations cannot impair the functioning of the external actuation lever in conjunction with the locking mechanism.
  • the receptacle for the lever in question may be designed as a receptacle bore into which the lever engages with its optionally formed axis.
  • a motor vehicle door lock is presented, which first of all ensures by the overhang realized on the reinforcing element that deformations of the outer door panel associated with an impact are intercepted by this reinforcing element and that Do not or hardly affect the function of the housing or the lock case. It is therefore still possible to open the motor vehicle door in question even after such an impact, from the outside. In addition, this contributes to the fact that the external actuation lever can be mounted on the reinforcing element in question.
  • the reinforcing element can be inexpensively combined with the housing or lock case, because the invention uses a snap-in or plug-in connection or an adhesive connection. This is where the main advantages can be seen.
  • Fig. 2 shows the object of FIG. 1 with the reinforcing element
  • Fig. 3 is a side view of the object of FIG. 2 from the direction X.
  • the figures show a motor vehicle door lock, the basic structure of which has a housing, which in the present case is designed as a lock case 1 or contains such a lock case 1.
  • Lock case 1 in cross-section is U-shaped with side walls 1b and 1c.
  • a ratchet 2, 3 of rotary catch 2 and pawl 3 is received in the lock case 1.
  • bearing pins 4 are anchored in a base plate la of the lock case 1 and accommodate the catch 2 or pawl 3.
  • a reinforcing element 5 is realized, which is a reinforcing plate 5.
  • the reinforcing plate 5 and the base plate 1 a of the lock case 1 are arranged essentially coplanar with one another, i. H. mostly parallel planes.
  • the rotary latch 2 and the pawl 3 are held between these two levels or the reinforcing plate 5 and the base plate 1 a.
  • the reinforcing plate 5 is fixed on the housing or lock case 1 with the aid of press fits 6. Details of the respective press fit 6 can best be seen from the enlarged detail in FIG. 2.
  • the reinforcing plate 5 then has recesses 7, through which fastening webs 8 extend.
  • the fastening webs 8 are integrally formed on the lock case 1 or protrude from its side wall 1b. Spring tongues 9 in the region of the recesses 7 engage in the indicated recesses 10 of the fastening webs 8 when the reinforcement plate 5 is positioned.
  • the respective rectangular recess 7 is equipped with a total of four spring tongues 9 on each side, which engages in the recess 10 formed as a circumferential groove in the fastening web 8.
  • this is not mandatory, other latching or plug connections or even an adhesive connection of the lock case 1 to the reinforcing plate 5 are also conceivable and are encompassed by the inventive concept.
  • a large number of interlocking or adhesive bonds are possible.
  • the reinforcing element or the reinforcing plate 5 as a whole ensures that the axes 4 of the catch 2 and the pawl 3 are properly fixed, namely between the relevant reinforcing plate 5 and the base plate 1 a of the lock case 1.
  • the reinforcing element or the reinforcing plate 5 has a lateral protrusion 11, which can be seen in particular in FIG. 2.
  • This protrusion 11 protrudes laterally beyond the housing 1 or the lock case 1 by the amount M, as the side view according to FIG. 3 immediately makes clear. It extends essentially in the opposite direction compared to a possible direction of impact which is indicated by an arrow A in the figures.
  • the direction of impact A extends essentially in the Y or vehicle transverse direction if one assumes a side impact. If the described force However, if the vehicle door lock is used for a tailgate, a rear impact must be taken into account, which is essentially congruent with the X or longitudinal direction of the vehicle.
  • the reinforcing element or the reinforcing plate 5 is essentially arch-shaped and has a recess 12 in the area of an inlet mouth 13 for a locking bolt 14, which is only indicated and which interacts with the catch 2.
  • a back 15 is provided, which essentially corresponds to the Supernatant 11 coincides.
  • two fastening legs 16 for the axes 4 of the catch 2 of the pawl 3 complete the reinforcing element 5.
  • the reinforcing element or the reinforcing plate 5 additionally has a receptacle 17 in the form of a receptacle bore 17 for a lever 18.
  • This lever 18 is the outer actuating lever 18, which is actuated by a merely indicated outer door handle 19 with the interposition of a connecting member 20, for example a rod or a Bowden cable.
  • the axes 4 of the catch 2 and pawl 3 may be riveted to the reinforcing element 5. This may also apply to a bearing mandrel or an axis 21 on the outer operating lever 18, wherein the outer operating lever 18 and bearing mandrel or axis 21 can form a one-piece structural unit.
  • the reinforcement element 5 or the reinforcing plate 5 is arranged substantially in the center compared to the inlet mouth 13. This means that when the rotary latch 2 is closed, the locking bolt 14 is located essentially in the center of the cutout 12 of the reinforcing plate 5.
