Definitions

  • the invention relates to a motor vehicle door lock, with a lock case and a locking mechanism mounted on the lock case, and with a reinforcing element for the lock case and / or the locking mechanism, the lock case being equipped with at least one connecting web which protrudes into a receptacle of the reinforcing element.
  • a reinforcing element which absorbs forces acting on the housing or the lock case without torque in relation to the locking mechanism.
  • the lock case is equipped with at least one fastening web for the reinforcing element, which protrudes into the associated receptacle of the reinforcing element.
  • the reinforcement element is connected to the lock case by means of one or more press fits. In this way, crash safety can be improved, particularly in the event of a side impact. An associated locking mechanism can consequently be opened more or less easily even after such a side impact.
  • a reinforcing element which is set up to support at least one lever of the locking mechanism and / or an obligatory lever mechanism.
  • the reinforcement element is equipped with at least one bearing pocket for the lever held therein between at least two bearing legs.
  • the prior art has basically proven itself when it comes to protecting the lock case and / or the locking mechanism from excessive deformation to protect against an accident, in particular a side impact.
  • deformations of the lock case or the locking mechanism in extreme cases, mean that a motor vehicle that has been involved in an accident or its motor vehicle door can no longer be opened.
  • a door opening is absolutely necessary, for example, to be able to rescue vehicle occupants by rescue workers or to enable vehicle occupants to get out on their own.
  • the approaches in the prior art are promising, but still leave room for improvement.
  • the invention is based on the technical problem of developing such a motor vehicle door lock so that any deformations of the reinforcing element as well as the lock case and the locking mechanism are reduced to a minimum and, in particular, improvements over the prior art are observed.
  • the invention proposes in a generic motor vehicle door lock that the connecting web engages with a predetermined clearance in the receptacle surrounding it in order to limit any deformations of the reinforcing element and consequently of the lock case and / or the locking mechanism.
  • the invention is based on the knowledge that, for example, in the case of a motor vehicle door lock for a motor vehicle side door and a side impact, corresponding forces can be absorbed primarily in the vehicle transverse or y direction by the locking bolt and the locking mechanism to a certain extent. If, in addition, there is a deformation of the locking mechanism or the lock case on which the locking mechanism is mounted, such deformations are allowed to a certain extent. Because, for example, when the lock case is deformed, the connecting web coupled to the lock case also follows this defor mation.
  • the reinforcing element Since the connecting web engages with a predetermined clearance in the surrounding him acquisition on the reinforcing element, the reinforcing element only acts from a certain degree of deformation of the lock case and consequently of the connecting web in the example.
  • the connecting web is not only displaced within the receptacle, but can also in principle perform axial movements without the reinforcement element being deformed directly as a result. Rather, such radial movements and axial movements of the connecting web within the receptacle are permitted to a certain extent and lead to the connecting web, for example, resting against the edge of the receptacle and being able to be moved axially with respect to the edge.
  • the reinforcing element unfolds its full effect and acts such deformations opposite. That is, the invention basically allows deformations of the lock case, at least in the area of the connecting web, which correspond to axial movements of the connecting web. In contrast, transverse movements of the connecting web are intercepted by the reinforcing element as soon as the connecting web has bridged the play within the receptacle surrounding it.
  • the invention is based on the further knowledge that Axialbe movements of the connecting web and consequently, to a certain extent, bulges of the lock case do not, or not significantly, negatively affect the functionality of the locking mechanism to a certain extent.
  • relative movements of the individual components of the locking mechanism to one another essentially the rotary latch and pawl, are suppressed with the aid of the reinforcement element or such relative movements are counteracted by corresponding deformations by the reinforcement element.
  • such relative movements directly influence the functionality of the locking mechanism, so that the invention specifically counteracts such conceivable movements as a result of the deformation of the lock case or the locking mechanism with the aid of the reinforcing element. This is where the main advantages can be seen.
  • the connecting web engages with pre-given radial play in the circular receptacle surrounding it.
  • the connecting web is mostly designed to be cylindrical.
  • the recording is a circular opening or circular recording.
  • the connecting web mostly engages centrally in the receptacle or circular receptacle.
  • the receptacle or circular receptacle surrounds the connecting web with a predetermined radial play.
  • the reinforcing element and the lock case are arranged essentially coplanar with one another.
  • both the reinforcement element and the lock case are each plate-shaped or largely plate-shaped components. That is, the reinforcement element is mainly designed as a reinforcement plate.
  • the lock case is mostly a lock plate. Due to the coplanar arrangement of the reinforcement element or the reinforcement plate and the lock case or the lock plate to one another, the two aforementioned plate-shaped elements define a free area between them.
  • the design is advantageously such that the connecting web bridges the free area in question between the reinforcing element and the lock case.
  • the connecting web can on the one hand be anchored perfectly in the lock case and on the other hand has the required length so that it can engage in the receptacle on the reinforcement element.
  • the reinforcement element and the lock case are arranged at a distance from one another.

  • deformations of the reinforcing element can be limited in a particularly effective manner essentially in a plane spanned by the reinforcing element.
  • the plane spanned by the reinforcement element usually coincides with a yz plane.
  • the y-direction corresponds to the transverse direction of the vehicle.
  • the z-direction coincides with the vertical axis direction of the motor vehicle.
  • the reinforcing element absorbs particular deformations of the motor vehicle door lock according to the invention in this plane spanned by the axis of the floch and the transverse direction.
  • the two connecting webs are arranged on the edge of the reinforcing element.
  • the lock case and the reinforcement element are also connected to each other via axes of rotation for the locking bolt. That is, the bolts, which also define the axes of rotation for the locking mechanism, ensure a firm and, at the same time, play-free connection between the lock case and the reinforcing element.
  • the connecting webs between the lock case and the reinforcement element are also provided.
  • the overall design is such that the bolts and the connecting webs are arranged following the edge of the reinforcing element and its contour.
  • the reinforcement element can prevent any deformations particularly effectively because the bolts and the connecting webs follow the edge and the contour of the reinforcement element and are therefore able to absorb particularly high torques compared to the locking bolts, which are mainly arranged centrally in comparison to the reinforcement element.
  • the respective connecting web serves not only to limit any deformations of the reinforcing element and consequently of the lock case and / or the lock. But the connecting web can connect the lock case to a lock cover as a further and second function. Lock case and lock cover taken together usually form a lock housing.
  • At least one web is provided which is formed on the lock case and rests on the edge of the reinforcement element in order to limit deformations occurring perpendicular to the reinforcement element plane.
  • the connecting webs in connection with the associated receptacles in the reinforcement element primarily ensure that deformations in the yz plane be limited.
  • the previously mentioned web formed on the lock case is now oriented in the x or longitudinal direction of the motor vehicle and primarily ensures that deformations of the motor vehicle door lock are prevented in this x or longitudinal direction of the motor vehicle.
  • a motor vehicle door lock is made available which particularly effectively prevents any deformation of the lock case and / or the locking mechanism or at least largely limits it. This ensures that the locking mechanism, in particular, continues to function even after an accident, which contributes to an enormous increase in safety.
