Automobile vehicle lock.

The invention concerns a lock of motor vehicle with the characteristics of the preamble of the claim 1.

The automobile vehicle lock from which is speaking covers in this case all kinds of motor vehicle locks, for example door locks side, bonnet locks, back door locks and especially trunk lid locks.

The well-known automobile vehicle lock (DE 101 58 733 A1) from which the invention is based equipped with the usual closing elements consisting of a Slip of the lock and a ratchet lock, can be brought the slip of the lock, in one embodiment, to an opening position, a main closing position and a pre-closing position The locking ratchet can be taken to a hitch position and it is prestressed in this position, in the which said ratchet keeps the lock slip in the main closing position. For coupling between the slip of the lock and ratchet lock, the slip of the Lock features a main latch and a predator. To liberate the slip of the lock, the locking ratchet can be passed to An extraction position. The slip of the lock located in the main closing position and in the pre-closing position is in retaining coupling with a closing wedge arranged usually in the body of the motor vehicle.

In the known automobile vehicle lock an accumulator lever is provided that can be carried to a hitch position and that is prestressed in this position, in the which said lever keeps the locking ratchet in position Extraction The accumulator lever can also be brought to an extraction position against its prestressing, which the locking ratchet can be released again. Yes, the lock slip being in the closed position main, the locking ratchet is now pulled out from its hitch position, the accumulator lever then falls into its hitch position and keeps the ratchet lock in its extraction position until the lock slip reaches  its opening position It is thus guaranteed that, in the case of a eventual delay in opening the door or vehicle cover automobile, avoid repeated locking of the locking ratchet and, therefore, an unwanted interruption of the operation of opening. This delay in opening the door or cover of the vehicle can be caused, for example, by door seals strongly frozen or similar. Another example of this is a rear boot cover covered with snow, in which case the weight of Snow retards or even prevents the lid from opening. By therefore, the previous accumulator lever is also called "snow load lever". The described retention function of the locking ratchet in the extraction position is called correspondingly also "snow load function".

While the snow load function guarantees optimum operating comfort during operation opening, this function frequently leads to operations wrong during closing operation. An example of this is the involuntary hitching of the accumulator lever when slamming with full force the door or cover of the motor vehicle. In this closing operation the closing wedge is coupled with the slip of the lock and, going through the pre-closing position, takes it from the opening position to the main closing position. While both, the locking ratchet slides with an appendix of snap along the back of the lock slip and fall firstly in the prefactor in the direction of its engagement position.  The locking appendix of the locking ratchet slides after additionally along the lock slip and it is then extracted again against its prestressing until finally it falls into its position of engagement in the main catch. The part of the lock slip between the predator and the main latch, which is coupled with the locking ratchet, thus form in some way an acceleration ramp for the ratchet lock in the direction of its extraction position. When now perform the closing operation with special speed, the sliding of the locking appendix of the locking ratchet to along the acceleration ramp then causes an acceleration from the locking ratchet to its extraction position or even even far beyond this one. In the vehicle lock known car this leads to a lever drop accumulator in its hitch position and therefore at locking ratchet interlock in its removed position. Be It has frustrated the closing operation.

To prevent malfunction described above of the automobile vehicle lock, the acceleration ramp, for example, can be more construction flat, which eventually leads to a reduction in depth of the main sear. However, in order to guarantee a secure closing position, the locking ratchet must be provided here, in contrast, with more prestressing. This is disadvantageous because a lock ratchet relapse on the back of the lock slip after opening of the door or cover of the motor vehicle is linked to a greater noise production This is perceived by the vehicle user. automobile as a decrease of comfort. In addition, the extraction of locking ratchet is linked to increased force consumption, which It is disadvantageous both for manual extraction and for motor extraction

In principle, retaining an identical design of the acceleration ramp, only one increased prestressing of the locking ratchet. However, this leads in a very marked way to the above described.

It can also be provided that the lever accumulator will only catch when the battery has been removed ratchet lock to an especially large extent. This reduces the probability of involuntary hitching of the accumulator lever during the closing operation. However, in this variant there are that also have a high noise production when returning to hook the locking ratchet.

Document DE 196 17 428 C2 shows another possibility to prevent malfunction before commented on the automobile vehicle lock. Apart from the snow load function, a function is also planned here suppressor suppression that prevents the locking ratchet from hitch before the lock slip has reached its Main closing position during closing operation. Do not However, the embodiment is linked to a high cost of building.

The invention is based on the problem of configure and refine the automobile vehicle lock known in such a way that, with little cost and without loss of comfort, reduce the risk of a malfunction of the motor vehicle lock caused by the lever accumulator

The aforementioned problem is solved in a motor vehicle lock with the characteristics of the preamble of claim 1 by means of the features of the characterizing part of said claim 1.

It is essential, first of all, knowledge of that the hitch of the accumulator lever is necessary for the operation only when the extraction of the ratchet lock in the opening operation frame. The opening operation is thus characterized because the ratchet of Lock is at the beginning in its hitch position. The Solution in accordance with this proposal takes advantage of this.

In effect, the accumulated lever removed is activated by moving the locking ratchet to its hitching position, so that only the accumulator lever located in the activated state may fall into its locked position due to its prestressing.

As a result, the lever drop accumulator in its hitch position is possible only when the locking ratchet first reaches its hitch position - activation of the accumulator lever - and then its position Extraction The hitch of the accumulator lever is limited substantially to the opening operation, which excludes widely the malfunctioning previously mentioned of the automobile vehicle lock.

The lock slip can be taken from preference in addition to a closed position in which said Slip is maintained by the locking ratchet located in a hitch position for pre-closing. Whenever the situation of pre-lock hitch is identical to the hitch position (for main closure), there is theoretically the risk of activation of the accumulator lever when, during the closing operation, the appendix locking ratchet lock go through the predator of the lock slip and snag so correspondent. However, the probability of such activation - involuntary - the accumulator lever is only reduced, since that, during the closing operation, the appendix blocking the locking ratchet collides in general with the slip of the lock in an area between the predator and the latch main - acceleration ramp - and the hitch position for pre-closing during closing operation usual.

However, to exclude the previous activation theoretically imaginable and unwanted accumulator lever during the closing operation it is planned according to the claim 2 that the engagement depth of the position of pre-lock hitch is smaller than the depth of hitch position hitch (for main closure). Dice that an activation of the accumulator lever is possible only by means of a displacement of the locking ratchet to the hitch position (for main closure), is now an unwanted activation of the lever entirely excluded accumulator during closing operation.

The previous activation of the accumulator lever can be guaranteed advantageously by means of a coupling special between the locking ratchet and the accumulator lever. The claim 3 concerns a preferred embodiment and constructively simple of this.

The preferred embodiment according to claim 6 leads to a compact and cheap variant of manufacturing in your set. In particular, the proposed execution according to the Claim 7 has technical manufacturing advantages.

The solution under this proposal is especially advantageous in a motor vehicle lock with auxiliary opening function according to claim 10. Here it is provided an auxiliary opening drive by means of which You can remove the locking ratchet. Drive opening auxiliary can be designed here with a power relatively weak, since with the solution according to the present proposal can be dispensed with especially high prestressing of the locking ratchet to prevent unwanted hitching of the accumulator lever during closing operation.

In the following the invention is explained using a drawing that represents only one example of realization. In the drawing they show:

Figure 1, a motor vehicle lock in accordance with this proposal with the lock slip located in the open position and with the accumulator lever not activated, a) in a plan view and b) in a side elevation according to the arrow I,

Figure 2, the automobile vehicle lock according to figure 1 with the slip of the lock located in the main closing position, with the locking ratchet located at the hitch position and with the accumulator lever activated, a) in a plan view and b) in a side elevation according to the arrow II,

Figure 3, the automobile vehicle lock according to figure 1 with the slip of the lock located in the main closing position, with the locking ratchet located at the extraction position and with the accumulator lever located in the hitch position, a) in a plan view and b) in an elevation lateral according to arrow III, and

Figure 4, the representation according to the figure 1, view a) without accumulator lever.

The drawing exclusively represents the components of a motor vehicle lock that are decisive to achieve the satisfactory result recommended by the invention. It is understood that the automobile vehicle lock in accordance with this proposal also presents all others components necessary for its operation.

The automobile vehicle lock represented It is equipped with closure elements consisting of a Slip 1 of the lock and a ratchet lock 2, being tilt the lock slip 1 around an axis 3 of the same and can be taken to an open position (figure 1), a main closing position (figure 2) and a position of Pre-closure not represented. Slip 1 of the lock features for this a main guarantor 4 and a predator 5. When the slip 1 of the lock is in the main closing position and in the pre-closing position, said slip 1 of the lock is in retaining coupling with a closing wedge 6 arranged usually in the body of the motor vehicle. Slip 1 of the lock is preferably prestressed towards its position of opening.

The locking ratchet 2 is tiltable around an axis 7 thereof and can be brought to a position of engagement and is prestressed in this position, in which said ratchet keeps slip 1 of the lock in the position of main closure For coupling with main catch 4 and the lock skid 1 preference 5, the ratchet of lock 2 is equipped with a lock appendix 8. The prestressing of the 1 slip of the lock, on the one hand, and the ratchet of blocking 2, on the other hand, can preferably be performed by means of a leg spring not shown or similar.

The locking ratchet 2 can be taken to an extraction position (figure 3) against its prestressing, with which the slip 1 of the lock can be released. He slip 1 of the lock can then tilt towards its opening position due to its prestressing and due to the force acting from the closing wedge 6 on the slip 1 of the lock. This is called in what follows operation of opening. The tilt of the lock slide 1 opening position to the main closing position with a subsequent fall of locking ratchet 2 in its position of hitch is called in what follows closing operation.

The automobile vehicle lock is equipped also with an accumulator lever 9 that is tiltable around of an axis 10 thereof and that can be brought to a position of hitch (figure 3) and is prestressed in this position, in which said lever keeps the locking ratchet 2 in its position of extraction. The prestressing of the accumulator lever 9 is carried out by a leg spring 11 shown in figure 2. The lever accumulator 9 can also be taken to an extraction position against its prestressing, which can release the locking ratchet 2 and this can swing in the direction of its hitch position.

When removing locking ratchet 2 out from its hitching position (figure 2), the accumulator lever 9 falls in its hooking position (figure 3) due to its prestressing and thus keeps the locking ratchet 2 in its position of extraction. The subsequent opening movement of slip 1 of the lock from the main closing position represented in Figure 3 in the direction of the opening position in turn causes removing the accumulator lever 9, taking it here firstly to an overcarriage position (figure 1) associated with the extraction position. The following explains the constructive execution of this coupling between slip 1 of the lock and the accumulator lever 9.

It is essential now that the lever accumulator removed 9 can be activated by the displacement of locking ratchet 2 to its position of hook and that only the accumulator lever 9 located in the activated state falls into its locked position due to its prestressed when removing the locking ratchet 2. It is planned for this a special coupling between the locking ratchet 2 and the accumulator lever 9.

Lock ratchet 2 is equipped preferably with a contour 12 with which a gear element 13 arranged on the accumulator lever 9. A through contour 12 and corresponding gear element 13, the locking ratchet 2 locks a first movement of the accumulator lever removed 9 until locking ratchet 2 reach your hitch position to activate the accumulator lever 9. It should be noted that the cancellation of this interlocking is that is, the activation of the accumulator lever 9, represents here only a necessary precondition, but not yet sufficient for hitching the accumulator lever 9. Indeed, only subsequent removal of the locking ratchet 2 leads to the Drop of accumulator lever 9 in the hitch position.

       \ newpage
    

The contour 12 and the gear element 13 each one of them can be arranged alternately in the ratchet lock 2 or on the accumulator lever 9. These two mutually complementary variants are equivalent to the operation described above. Therefore, all the explanations The following apply equally to both variants.

In the embodiment shown and preferred in this regard the locking ratchet 2 may be taken to a hook position for pre-closure not shown, in which it keeps slip 1 of the lock in the position of pre-close During the closing operation, the locking appendix 8 of ratchet lock 2 slides first along the spine 14 of the slide 1 of the lock until said appendix falls into the skid 1 of the lock 1 in the direction of its hitch position and collides again with slip 1 of the lock in an area between the prefrator 5 and the latch main 4. This area is called acceleration ramp 15 in which follows, as the locking ratchet 2 slides along of the acceleration ramp 15 when the slide is additionally tilted 1 of the lock and is thus accelerated in the direction of its position of extraction. As described above, this acceleration can lead to the locking ratchet 2 reaching its position of extraction or even a position of overcarrera. Since in this state, according to the present proposal, the accumulator lever 9 is not activated yet, this acceleration of the locking ratchet 2 does not cause unwanted hitching of accumulator lever 9.

Finally, by additionally tilting the Slip 1 of the lock, the locking appendix 8 passes through the main latch 4 and falls into its locked position (figure 2). In principle, it can be provided now that the hitch position for pre-closure is identical to the hitch position (for closing main), so that, in case of a slow closing movement, the fall of the locking ratchet cannot be completely excluded 2 in its position of engagement in the predator 5. The consequence would be the unwanted activation of the accumulator lever 9. To safely exclude this, the depth of position drop of pre-lock hitch is smaller than the depth of drop in hitch position (for main closure). Does not have place then, surely, a lever activation accumulator 9 not even when the preacher 5 is reached.

In what follows we want to imply fundamentally with "hook position" the position of hook (for main closure) of the locking ratchet 2.

In the closing operation described above the accumulator lever 9 is initially maintained still by the Slip 1 of the lock in an extracted position. Strictly speaking, it it is about an overcarriage position associated with the position Extraction Due to the engagement of the closing wedge 6 with the Slip 1 of the lock, this slip 1 scales then on direction to its main closing position and ceases to be coupled with the accumulator lever 9, with which this accumulator lever 9, due to its prestressing, it is applied with the element of gear 13 to contour 12. The accumulator lever 9 is retained then by locking ratchet 2 through contour 12. When slip 1 of the lock now reaches its position of main closure (or an overcarriage position associated with the main closing position), the locking ratchet 2 falls into the hitch position represented in figure 2. Contemplation joint of figure 1 and figure 2 shows that, during the locking ratchet hitch 2, the contour 12 slides first along the gear element 13 until the contour 12 is finally decoupled from the gear element 13. Due to the prestressing of the accumulator lever 9, the gear element 13 and the contour 12 then exceeds each other and the lever accumulator 9 is applied to a seating surface 16 of the locking ratchet 2 - accumulator lever 9 is activated. During a subsequent removal of the locking ratchet 2, the accumulator lever 9 finally passes beyond the surface of seat 16 and falls into its locked position. This is represented in Figure 3. In this hook position the accumulator lever 9 is coupled with another seating surface 17 of the ratchet of lock 2.

It follows from the above description the fact that, according to the solution of this proposal, the attachment of the accumulator lever 9 is configured in two stages, so that the activation of the accumulator lever 9 must precede the arriving at the engagement position of said accumulator lever 9.

In an especially preferred embodiment the anterior contour 12 is oriented substantially in the form of circle arc around axis 7 of the locking ratchet. In the complementary embodiment with a contour 12 arranged in the accumulator lever 9 is meant by this a corresponding orientation of the contour when the lever accumulator 9 is in the extraction position. Without However, the contour 12 may also be of straight configuration and eventually even present inflection points. In the example of embodiment represented and preferred in this regard is advantageous also the contour configuration in terms of this extends far enough - to the left in figure 1a) - to exclude involuntary activation of the accumulator lever 9 even in the case of a particularly large extraction of the ratchet lock 2.

In the embodiment shown, the contour 12 is configured as a nerve with an extension in height in the direction of axis 7 of the locking ratchet. This is can recognize in representation b) of each of the figures 1 to 3. Figure 4 allows the shape of the contour 12 configured as a nerve.

For contour configuration 12 are imaginable, depending on the case of application, numerous others realization possibilities For example, contour 12 can be configured as a slit in a wall segment, such as an edge or like a heel.

The concept described above with contour 12 and gear element 13 makes it necessary that, when removing the accumulator lever 9 out of the hitch position, the gear element 13 change from one side of the contour 12 to the other side of said contour 12. At the same time, contour 12 has to prevent in this state a replacement of the accumulator lever 9, since the locking ratchet 2 is not here in the position  latching and lever activation is not desired accumulator 9.

Removing the accumulator lever 9 has provided, in a preferred embodiment, an overshoot of the contour 12 and a subsequent insertion of the accumulator lever 9 behind the contour 12. The accumulator lever 9 is configured for this in at least partially elastic shape. However, it may be in principle also provided that, alternatively or additionally, locking ratchet 2 is configured so corresponding as partially elastic. With "fit" of the accumulator lever 9 does not necessarily mean a force transmission joint between the gear element 13 and the outline 12. Essential here is only that, after overshoot of contour 12, is prevented by means of this contour 12 a replacement of the accumulator lever 9.

A possibility to materialize elasticity described above is the spring-loaded arrangement of the gear element 13 on the accumulator lever 9 or, in case of a complementary arrangement, in the locking ratchet 2. This spring-loaded arrangement of the gear element 13 can guaranteed, for example, by means of a spring element separated. However, particularly in the technical aspect of manufacturing is advantageous if the gear element 13 is arranged on a tongue 18 with lever spring action accumulator 9 or, in case of a complementary provision, of locking ratchet 2, especially in one execution preferred than the accumulator lever 9 or, in case of an arrangement  In addition, the locking ratchet 2 is configured as a piece of plastic and especially as a casting injected monobloc. Of course, both the ratchet lock 2 as the accumulator lever 9 can also be manufactured as a piece of plastic and especially as a casting injected monobloc.

In Figures 1 to 3 it can be seen in the accumulator lever 9 a tab 18 described above provided of spring action. The accumulator lever 9 is configured as a piece of cast iron injected monobloc, the tab 18 with a peripheral edge 19 inside the lever accumulator 9.

The above described overshoot of contour 12 with subsequent insertion of accumulator lever 9 can be encouraged by a corresponding configuration of the gear element 13. In the embodiment shown and preferred in this regard the gear element 13 has a first gear surface 20 which, when the lever is removed accumulator 9, can be coupled with contour 12. The element of gear 13 also has a second gear surface 21 that comes to engage with contour 12 during the movement of Slip opening 1 of the lock - and therefore during the contour exceeding 12 -. To make possible now the contour overflow 12 only in the direction above indicated, the first gear surface 20 extends substantially in the direction of the axis 10 of the lever accumulator, while the second gear surface 21 is extends substantially obliquely with respect to the axis 10 direction of the accumulator lever. It gets like this in set that a contour overflow 12 is possible only when moving accumulator lever 9 from the hitch position in the direction of its extraction position. Therefore, the element of Gear 13 is configured in the manner of a cicada. According to him case of application, other executions may also be provided and arrangements of the gear element 13.

It has been explained above that the movement of opening of the slide 1 of the lock causes the removal of the accumulator lever 9. They are provided for this in slip 1 of the lock a guide surface 22 and on the accumulator lever 9 a guide surface 23 corresponding to it. Starting off of the main lock slide 1 lock position, depicted in figure 3, a tilt of slip 1 of the lock in the direction of the opening position causes the coupling between the two gear surfaces 22, 23, with that the accumulator lever 9 is pressed in the direction of its extraction position. After exceeding contour 12, the arrangement is found in the position represented in Figure 1. The accumulator lever 9 is located here in a overcarriage position associated with the extraction position. He Slip 1 of the lock keeps the accumulator lever 9 in this position. However, this does not have to be this way. The lever accumulator 9 could, for example, be applied here already with the gear element 13 to contour 12.

Finally, it should be noted that in a especially preferred execution a drive is provided opening auxiliary, not shown, by which you can remove the locking ratchet motor 2. The advantages of solution in accordance with this proposal, especially regarding of the design of the auxiliary opening drive, have been explained higher.
