Definitions

  • the invention relates to a motor vehicle door lock according to the preamble of claim 1.
  • such a motor vehicle door lock or one with a comparable structure is fitted inside or on a motor vehicle door.
  • side door locks that is to say motor vehicle door locks which are arranged in the interior of a side door.
  • a locking bolt interacting with the motor vehicle door lock is connected to a body, for example to a B pillar of a motor vehicle body.
  • the basic topological conditions and the interplay of the locking bolt with the locking mechanism consisting essentially of a rotary latch and pawl is shown in the DE 32 34 103 C2 described.
  • the lock case has typically been designed to be massive in order to be able to cope with bending stresses and, in particular, the forces arising in the event of an impact.
  • L-shaped lock cases are used, for example in the WO 2009/056 120 A2 are described by the applicant.
  • a lock case which is largely L-shaped in cross section, is realized, which on the one hand describes the locking plane which largely carries the locking mechanism and on the other hand the front plate level which is different from this.
  • the locking level corresponds to an L-leg of the lock case, whereas the face plate level represents the other L-leg of the lock case. Since the motor vehicle door lock essentially at the front plate level with the associated motor vehicle door and is coupled in particular the motor vehicle side door, then the front plate level is mentioned, which extends at an angle in comparison to the locking level.
  • end plate level is not to be understood as restricting the fact that the motor vehicle door lock in question is or must be connected to the associated motor vehicle door on or by means of this end plate level. Rather, the term “face plate level” expresses that this is a level which deviates from the locking level and which, in comparison to the one and the locking level associated L-leg, characterizes the other L-leg of the lock case with an L-shaped cross section.
  • a motor vehicle door lock according to the DE 20 2010 007 353 U1 the lock case is connected with its front plate level to a motor vehicle side door, specifically to a front plate of the motor vehicle side door in question.
  • a motor vehicle side door regularly has an outer panel, an inner panel and the end panel already mentioned and connecting the inner panel to the outer panel.
  • EP 0 331 832 A1 describes a motor vehicle door lock according to the preamble of claim 1.
  • the lock case is U-shaped in cross section.
  • the lock housing is detachably connected to the lock case, namely by means of screws and threaded holes in a cover plate.
  • the front plate level of the lock case or the lock case itself is equipped with only the two side parts that line the mouth, without bridge parts, whereas the lock housing functions wholly or partly as a bridge replacement part or defines the bridge part.
  • the faceplate level is spanned by the lock case unchanged, in the present case described by the two side parts.
  • the bridge part which is also arranged in the face plate plane, is located on the lock housing or is defined here.
  • the invention provides a weight-optimized embodiment while maintaining the security standard.
  • the lock case consequently dispenses with the bridge part between the two side parts. That is, the lock case previously comprising the two side parts and the bridge part is reduced to the two side parts according to the invention.
  • the invention is based on the knowledge that the lock case is typically a steel component. As a rule, the lock case is punched and / or formed from sheet metal and in particular sheet steel. The omission of the bridge part between the two side parts now leads to the described significant weight reduction in view of the material used (steel).
  • the invention is based on the knowledge that the tearing forces acting on the motor vehicle door lock in an accident primarily act on the locking plane of the lock case and the two side parts. In contrast, in the area of the bridge part of the lock case according to the prior art, relatively low forces occur, which according to the invention can also be controlled by the lock housing, which is largely made of plastic.
  • lock housing is permanently connected to the two side parts.
  • the two side parts of the lock case that line the inlet mouth are each coupled to the lock housing.
  • the area of the lock housing that connects the two side parts of the lock case to one another functions as a bridge part replacement area or as a bridge part.
  • the permanent connection can advantageously be designed as a clip connection.
  • the two side parts mostly each have a receiving opening.
  • a web and in particular a clip web engage in the receiving opening.
  • the bridge or clip bridge is provided on the lock housing, whereas the receiving opening in the side part is observed on the lock case.
  • the lock housing is formed in two parts with a lower shell and an upper shell. As a result, the rigidity of the lock housing against bending stresses can be increased. This also makes assembly easier.
  • the lower shell of the lock housing connects the two side parts of the lock case to one another and in this respect has the bridge part replacement area or the bridge part.
  • the design is usually made so that the lower shell describes a division level.
  • the bridge part replacement area or the bridge part on the lower shell is raised opposite this division level.
  • the lock case is mostly made of steel.
  • the lock case is typically a sheet metal part made of steel, which is punched and / or shaped.
  • the shape of the lock case is chosen so that it at least partially encompasses the lock case.
  • the lock housing is itself made of plastic. As a rule, this is a plastic injection molded part.
  • a motor vehicle door lock is made available which, while maintaining the safety standards, in particular with regard to tensile tests or accident safety, fulfills the requirements, but at the same time has a significant weight saving.
  • this can be attributed to the fact that the massive lock case is designed without any bridge parts. This means that the lock case or its front plate level is practically only (still) described by the two side parts that line the inlet mouth. In contrast, the massive bridge part made of steel in the lock case has proven to be unnecessary.
  • the invention achieves that the function of the bridge part on the lock case made of steel in contrast to that made of plastic Lock housing is taken over and can also be taken over.
  • the lock housing actually functions in whole or in part as a bridge spare part or defines the bridge part. Since the lock housing was already present in the area of the bridge part on the lock case according to the prior art, according to the invention the bridge part on the lock case can be omitted without replacement. The area of the lock housing provided at this point in the prior art, in contrast, functions according to the invention as a bridge replacement part or bridge part.
  • any forces acting on the side parts can be transmitted to and absorbed by the lock housing. This is ensured by the clip connection advantageously provided in this area between the side part on the one hand and the lock housing on the other hand.
  • the lock housing is equipped with, for example, an integrally molded web and in particular a clip web in the area of the associated receiving opening of the side part.
  • the lock housing and the lock case encompassing the lock housing form a structural unit which, overall and within the scope of the invention, meets the required security requirements, and even without the missing bridge part on the lock case between the two side parts. This results in enormous weight savings that were previously not considered possible. All of this works without sacrificing security. This is where the main advantages can be seen.
  • the invention is explained in more detail below:
  • the embodiment of a motor vehicle door lock according to the invention is described in the present case and is not restricted to a motor vehicle side door lock.
  • the motor vehicle door lock in question is consequently fastened inside a motor vehicle door and in particular a motor vehicle side door.
  • a locking bolt which is arranged on an associated motor vehicle body, interacts with the motor vehicle door lock shown.
  • the locking bolt is usually located on a B-pillar or C-pillar of the motor vehicle body in question.
  • the motor vehicle door lock is regularly attached to a front plate and / or inner plate of the motor vehicle door.
  • the end plate of a motor vehicle door or motor vehicle side door connects an outer plate to an inner plate.
  • an attachment to the outer sheet is of course also conceivable.
  • the motor vehicle door lock shown is fixed to the front plate and / or inner plate of the motor vehicle door in question.
  • the front plate of the motor vehicle door runs essentially at the same level as a plane of the motor vehicle door lock.
  • the basic structure of the motor vehicle door lock as such is composed of a lock case and a locking mechanism mounted in the lock case.
  • the locking mechanism consists of a rotary latch and a pawl.
  • a further basic structure includes a lock housing which is connected to the lock case.
  • the lock case is largely L-shaped in cross-section. In fact, the lock case describes a locking level and a different front plate level.
  • the end plate level of the L-shaped lock case essentially coincides with the plane spanned by the end plate of the motor vehicle door or is arranged parallel to it.
  • the faceplate level there is an inlet mouth, via which the locking bolt, which in the example is attached to the B-pillar, moves into the motor vehicle door lock shown and can then interact with the locking mechanism.
  • the face plate level is equipped with at least one bridge part spanning the inlet mouth and two side parts.
  • the two side parts line the mouth.
  • the inlet mouth is arranged between the two side parts.
  • the face plate level of the lock case or the lock case is designed as such without a bridge part and has only the two side parts that line the inlet mouth.
  • the face plate plane is only spanned by the two side parts of the lock case.
  • there is no bridge part of the lock case which has been made mandatory in the prior art and has previously connected the two side parts to one another.
  • this bridge part takes over the lock housing within the scope of the invention.
  • the lock housing functions entirely or partially as a bridge spare part or defines the bridge part.
  • the bridge part is still arranged in the face plate plane.
  • the two side parts are coupled to the lock housing.
  • an area of the lock housing that connects the two side parts of the lock case to one another can function as a bridge part replacement area or as a bridge part.
  • the lock housing is permanently connected to the two side parts in the exemplary embodiment described.
  • a clip connection is implemented for the permanent connection of the two side parts to the lock housing 5.
  • the clip connection continues in the exemplary embodiment together on the one hand a receiving opening in the respective side part and on the other hand a web engaging in the receiving opening.
  • the web is a clip web, which is arranged on the lock housing and is molded onto the lock housing in the context of the exemplary embodiment.
  • the web or clip web molded onto the lock housing is triangular in cross section, such that the web or clip web forms a leg projecting almost perpendicularly from the lock housing.
  • This protruding leg together with a slope connected to it, defines the length of the web or clip web or clip web.
  • the web has a rectangular shape when viewed from above.
  • the receiving opening is also equipped with a rectangular shape adapted to the rectangular shape of the web.
  • the lock case can be connected to the lock case in the assembly direction in such a way that first the bevel slides along the side part and then the web with its leg, which projects essentially vertically with respect to the lock housing, an upper edge of the Reaches behind the receiving opening. In this way, the clip connection is made and the lock case is permanently connected to the lock housing.
  • the lock housing is composed of a lower shell 5a and an upper shell.
  • the design is such that the lock case is permanently coupled to the lower shell of the lock housing, in the exemplary embodiment with the aid of the clip connection, as has already been described.
  • the upper shell is then connected with the assembly from the lock case and the lower shell. This can be done again via clip connections or screw connections (not shown) or whatever, at the same time a seal to be inserted between the lower shell and the upper shell ensures a media-tight closure of the lock housing.
  • the lower shell has the bridge part replacement area or the bridge part which couples the two side parts of the lock case to one another.
  • the bridge part replacement area or the bridge part as part of the lock housing or the lower shell, any movements of the side parts against one another in the event of a crash or a safety test simulating a crash are absorbed and the two side parts are stiffened like a bridge. Deformations occurring in this case correspond, according to the invention, predominantly to an action on the lock housing in its longitudinal extent. A particular stiffness is observed in this direction.
  • the fact that the lower shell, as part of the lock housing generally describes a division level with the bridge part replacement area or the bridge part that is raised, also contributes to this.
  • the lock case is typically made of steel. This is usually a sheet metal part made of steel, which is punched and shaped L-shaped as shown.
  • the lock housing is made of plastic. It has proven itself here if the lock housing is designed as an injection molded plastic part. This applies in particular to both the lower shell and the upper shell.
