Description

The invention relates to a motor vehicle lock with a lock holder, which consists of a base plate to be determined on the lock housing with retaining holes and a lock holder bolt cooperating with the locking mechanism.

Such motor vehicle locks are basically known. The DE 20 2007 012 253 A1 describes a lock holder, which is designed so that designed as a flat band upper hoop bar is designed so that it extends beyond the inlet region of the lock plate, whereby an increased tensile strength of the locking mechanism in the closed state in the event of a crash is achieved by this measure. The associated lock holder is made in two parts, wherein the lock holder pin is a separate component which is captively connected to the bracket and the bracket. The actual lock holder bolt has at the end a serving as a collar strap, which is to stabilize this entire component so that after a crash, the lock can be opened further. The structure is relatively expensive and in the connection of the base plate and lock holder pin exact positions and dimensions must be guaranteed. From the EP 2 031 158 A2 a lock holder for power locks is known, which is made in one piece by cold deformation. This type of lock holder is preferably manufactured by cold pressing and that cheaper than such lock holder types, which are basically made in two parts. Nevertheless, the effort is considerable here too. The same applies to lock punch produced as a stamped part, which according to DE 102 52 748 A1 can be made in one piece. Finally, out of the WO 2006/053431 A1 one by punching and punching in one piece manufactured lock holder for motor vehicle locks, which can also be produced in unusual geometries. A disadvantage of these known lock holders in total, above all, the rather complex structure of the individual holder, with most of the bracket come as a retaining bolt or locking bolt used. As a rule, reworking is essential in these known lock holders in order to secure the subsequently secure installation of the lock holder in the motor vehicle lock and operation there.

The invention has for its object to provide a motor vehicle lock with a lock holder that is inexpensive to produce both in large and in smaller quantities and reliable.

The object is achieved according to the invention in that the lock holder pin punched together with the base plate of a sheet together and that the punched-out central plate, the horizontal base plate and the approximately perpendicular to the lock holder pin resulting are folded.

The folding of a sheet is basically known, but here, first of all, one of the dimensions forth low-priced base plate or central sheet is punched out, with only a relatively small committee arises. When punching this central sheet at the same time further required notches, holes or punches are prepared, which will be described later. It is important that such a central sheet is then simply folded several times, so that from the central locking bolt and the perpendicular protruding parts of the base plate arise. Thus, a lock holder is then given, which can be installed as such in a motor vehicle lock and fixed there that can also intervene safely through the miterzeugten with recesses and the like, the locking mechanism, which is also further explained and described in more detail below. With just a few individual steps, a finished lock holder can be made available that no longer requires further processing.

For connecting this folded lock holder with the actual lock housing retaining holes are required, which are punched out in accordance with a further step of the invention in punching the same. In one step, thus, a stable component is created, which can be achieved by the fact that the closing holder pin quasi a double sheet and low crash values. The lock holder is advantageously stable, can be easily and safely connected to the lock housing and is then immediately available for the necessary functions in the motor vehicle lock.

A particularly expedient embodiment is that in which the central sheet is folded downwards in the center and in the region of the holding bores, resulting in the closing holder pin and the base plate being folded. As already mentioned is thus a practically consisting of two vertical and mutually parallel plate parts existing lock holder pin, which is advantageously stable and in the necessary recess for the intervention of the catch can be easily introduced and as taught further back simultaneously with the punching.

According to the teaching of the invention, the necessary recesses are created equal to the sheet metal stamping, wherein it is provided that at a distance from the central fold U-shaped lid are punched, which are folded against the latter in the manufacture of the central fold by 90 ° to the outside. Since these are congruently mounted and formed, thus the necessary recess is available, in which the catch can engage when the lock is operated. The punches referred to as lids remain on the lock holder and act as a kind of crash protection, because they bent by 90 ° allow supporting other components on these lock holder parts. Of course, there is also the possibility to produce corresponding recesses at the same punching, except that then no lid are available that can exercise the other functions; Nevertheless, such a trained component would result in an advantageously shaped lock holder.

The assembly as well as the operation of a correspondingly trained lap holder is facilitated by the fact that the base plate has rounded corners. These rounded corners are produced at the same time as punching out and advantageously avoid injuries during installation because sharp corners can be safely avoided.

In order to specify the crash protection described above, it is advantageous if the lids are formed at right angles to the lock holder pin projecting and reaching close to the central fold. The back of the central fold is practically widened by these bent lid, so that the described crash protection can be additionally realized without the need for a separate component. It is advantageous at the same time that the effect of the raised locking bolt is selectively enhanced by the protruding ears or the protruding cover.

Another embodiment of the motor vehicle lock according to the invention or the lock holder required for this is that in which the base plate consists of two sub-plates, each with one or more retaining holes, which are interconnected via a web, resulting folded a rectangular bracket and folded over his stirrup leg with the Base plate is connected, wherein one of the two stirrup legs, the closing holder pin is formed resulting. In such a design, the two sub-panels and connecting them bracket or web are also punched together in a single operation from a sheet, which due to the shape given here a larger committee forcibly arises. The two sub-plates of the base plate are both far away from each other during punching as well as later in the folding off and are connected via appropriate screwing or the like through the retaining holes through to the lock housing or fixed to the bottom plate. The two sub-panels are correspondingly far from each other and are connected to each other via the web or bracket, which is folded after punching out so that it results in a rectangular bracket, so that one of the two bracket legs advantageous can be used as a lock holder bolt. It is stabilized so that the catch can wrap around it and close the lock, without the risk that when unjustified actuation or any overload of these stirrup legs of the load can no longer stand. Rather, it is provided here that one of the two stirrup legs is reinforced in such a way that a fully integrated and stable lock holder pin is available.

This reinforcement of the stirrup leg is achieved according to the invention, for example, by the fact that the bar leg resulting in the striker pin has notches to which the stirrup legs are folded in order to reinforce the pre-drawn flap during folding of the lock holder. This stirrup leg is then perpendicular to the sub-plate and the base plate and can thus optimally perceive its function with the catch together, especially if it is designed reinforced as described.

This reinforcement is improved according to the invention in that the notches on the lock holder pin or on the bar arm are formed at right angles to the longitudinal axis of the stirrup leg and that the tabs arc-shaped and thus roundings resulting folded. As such, the stirrup leg is reinforced by the notches and tabs because these tabs are wrapped around the remainder of the stirrup legs, either bent or folded so that they can contribute to the desired reinforcement. They can even be bent as described, so that they still favor the effect of the catch and cling to them.

During installation, a design makes particularly advantageous, according to which the rectangular bracket has a widened relative to the two bracket legs base plate. This base plate helps ensure that the rectangular bracket can perform its support function optimally and can ensure that in the event of a crash, the lock remains functional as such. The base plate can easily have twice the width of the bar arms and go over into the hanger arms, so that the desired additional stability is achieved.

The punched-out central sheet develops the necessary stability and supporting effect, in particular, in an advantageous manner if the two partial plates are arranged and configured offset from one another in a manner opposite to the rectangular bracket. The two sub-panels are thus in the assembled state on both sides of the rectangular bracket, so that during installation by the introduction of screws on both sides of the central rectangular bracket high stability values.

According to a further advantageous embodiment, it is provided that the two sub-plates strip-shaped protruding lugs that extend the sub-plates practically and give the opportunity to be mounted engaging with these sub-panels in other components.

The invention is characterized in particular by the fact that simple basic components for the lock holders are created from the production, which are then brought by simple folding in the appropriate design, so that a post-processing after assembly is no longer required. The important components such as the lock bolt as such is stabilized by skillful design so that he can fully meet the intended function and also effectively absorb the transmitted from the catch forces and forward. The locking bolt and the base plate form a common component which is punched out in one operation and is then provided with the necessary recesses and holes, to then be used without further processing or reworking in a lock housing. Depending on the size of the lock housing or the intended motor vehicle lock expedient training for the lock holder can be realized without having to deviate from the basic design. By folding or molding of the respective lock holder with base plate and lock bolt increases the Stability of the overall component advantageous, which can be strengthened by additional measures, in particular, the locking bolt as such, without the need for additional steps to do so, all the necessary steps can be practically used already during punching and folding.

FIG. 1 schematically shows a portion of motor vehicle 25 and here again part of a motor vehicle door 26. This motor vehicle door 26 has a motor vehicle lock 1 positioned below the window 27, reproduced here in an enlarged view. From this motor vehicle lock 1 is the lock housing 2 and some items shown. In particular, these parts include the locking mechanism 3 with the rotary latch 4 and the pawl 5, in which case the locking mechanism 3 is reproduced in the locked position. A lock holder 7 is received by a rotary latch 4, which is blocked by conditioning the pawl 5 in this position. If the motor vehicle lock 1 is actuated, the said pawl 5 is lifted, so that the rotary latch 4 pivots in its initial position and the lock holder 7 releases. The lock holder 7 is shown here only as a circle, wherein it is described in more detail in the detailed embodiment in the other figures. This lock holder 7 should be designed so stable that it does not hinder the function of the entire motor vehicle lock 1 even after an accident, so it is crash-proof.

The lock holder 7 is according to FIG. 2 Both are a component and are as such as the central plate 10 danced together, which FIG. 3 clarified. When punching the retaining holes 11, 12 are punched in the base plate 8 at the same time, as well as the two here as a lid 17, 18 marked indentations or incisions, which then later according to FIG. 2 and FIG. 4 be bent so that then the recess 19 results and also in addition the protruding ears 24, which serve to stabilize the whole, especially the increase in crash safety. The recess 19 is used as described above, the introduction of the rotary latch 4, which is easily possible because the two recesses 19, 19 'are congruent, in particular the FIG. 2 can be removed. The gap 22 formed between the two plates forming the lock holder pin 9 is in no way detrimental, but instead leads to a very stable lock holder pin 9. This lock holder pin 9 is formed when the folds 14, 15 and 16 are produced from the central panel 10. Initially, the 180 ° fold 14 is generated and at the same time the right and left folds 15, 16 by 90 °. Next, the lid 17, 18 and the protruding ears 24 are folded with. The corners 20, 21 are rounded, as well as the round corner 23 to the protruding ears 24, so that folds in the subsequent processing of the lock holder 7 thus produced can not occur. After the folding process, this results FIG. 2 and FIG. 4 apparent component, which can then be installed in the lock housing 2. The wide back 28 of the central fold 14 stabilizes the entire component and increases the crash safety, which is additionally increased by the protruding ears 24.

The FIGS. 5 to 8 show a further embodiment of the lock holder 7, which in turn here by a punching process, a central plate 10 is produced, which has at both outer ends of the partial plate 30, 31 with the retaining holes 11, 12. These two partial plates 30, 31 of the base plate 8 are connected to each other via a web 32 and a rectangular bracket 33 after folding. This rectangular bracket 33 is correspondingly in a bow-shaped manner over the partial plates 30, 31, so that this results in stirrup legs 34, 38, of which the stirrup leg 34 is simultaneously designed as a locking holder pin 9. This is in the FIGS. 5 and 6 indicated accordingly. About notches 35, 36 reaches tabs 37, which are then bent around the residual web 45 around and arcuate, so that there is an optimal rounding, which favorably promotes the insertion of the rotary latch 4.

The two sub-panels 30, 31 project in opposite directions beyond the rectangular bracket 33, so that this rectangular bracket 33 can advantageously be stabilized with the bracket legs 34 and 38. This is further promoted by the fact that a base plate 39 is provided centrally, which is significantly widened compared to the stirrup legs 34, 38 and virtually results in a cover plate which is offset in the plane but parallel to the two sub-plates 30, 31 runs. FIG. 7 illustrates this, and it is also clear that both sub-plates 30, 31 have protruding lugs 40, 41, which favor the assembly and the stability of the entire lock holder 7. Both in the Figures 5 as well as 7 and 8, the areas of the folds are marked separately. Thus, the reference numeral 41, the fold between the Lock holder pin 9 and the sub-plate 31 characterized, while the folding area 42, the folding between the lock holder pin 9 and base plate 39 shows. The folding area with the reference numeral 43 is located between the base plate 39 and the second bracket leg 38 and the folding area 44 lies between the partial plate 30 and the second bracket leg 38.

FIG. 7 shows a plan view of the folded lock holder 7 during FIG. 8 this lock holder 7 reproduces in perspective. Here it is clear that the two bar arms 34, 38 projecting with the base plate 39 connecting them high above the two partial plates 30, 31, so that then the two bracket legs 34, 38, the recess 19 pretend or may include, in which the catch is led into it.

All mentioned features, including the drawings to be taken alone, are considered to be essential to the invention alone and in combination.
