Definitions
- the invention relates to a motor vehicle lock with a lock latch pivotable about a lock latch axis according to the preamble of claim 1.
- the motor vehicle lock in question can be assigned to any locking element of a motor vehicle.
- trunk lids, trunk lids, front hoods, in particular engine hoods, side doors or the like can be used.
- These closure elements can be designed to be pivotable or in the manner of sliding doors.
- the high level of crash safety is an important requirement for motor vehicle locksmiths.
- the aim is to avoid an unintentional opening process in the event of a crash, even if extraordinarily high crash forces are introduced into the lock latch via a striker.
- the known motor vehicle lock (EP 2 492 423 B1), from which the invention is based, has a lock latch which can be pivoted about a lock latch axis and which usually interacts with an above striker.
- the motor vehicle has a locking mechanism made up of a pawl arrangement and a blocking arrangement blocking the pawl arrangement.
- the locking pawl arrangement is composed of a carrier pawl and a pawl pivotably mounted thereon, which provide a toggle lever mechanism.
- Such a two-part pawl arrangement basically enables a high level of user comfort with regard to low operating forces and low noise during the closing and opening process.
- the connecting joint between the carrier pawl and the locking pawl represents a weak point when it comes to absorbing the high crash forces mentioned above.
- the invention is therefore based on the problem of designing and developing the known motor vehicle lock in such a way that the crash safety is increased.
- the above problem is solved in a motor vehicle lock according to the preamble of claim 1 by the features of the characterizing part of claim 1.
- What is essential is the fundamental consideration that a certain deformation-related yielding of the pawl or its pivot bearing, which is due to the crash forces transmitted by the locking part, is accepted.
- a crash locking surface is provided against which the locking pawl can rest in order to divert the crash forces.
- the above yield is due to a deformation of the pawl or its pivot bearing or any components coupled to the pawl, via which part of the crash forces are diverted.
- a crash locking surface is provided and that an engagement surface of the locking pawl comes into engagement with the crash locking surface in the event of a deformation-related yielding of the locking pawl or its pivot bearing, which is due to the crash forces transmitted by the closing part, so that at least one part the crash forces are derived via the crash barrier area.
- the crash safety can be increased using simple constructive means.
- the components of the locking mechanism can be designed to be mechanically weak and thus cost-effective, without impairing the envisaged increase in crash safety.
- Claim 2 relates to a preferred design of the blocking arrangement for blocking the pawl arrangement in the blocked state.
- a toggle lever mechanism is used in a variant, which has particular advantages in terms of ease of use.
- the proposed solution can be applied particularly effectively to a two-part pawl arrangement according to claims 3 to 5.
- the convenience of use associated with the two-part design of the pawl arrangement is combined here with a particularly high level of crash safety.
- the above-mentioned, inexpensive design of the pawl arrangement is expressed according to claims 6 to 8 in the use of plastic material for at least part of the pawl arrangement.
- claim 6 relates to the design of the pivot bearing of the pawl made of a plastic material
- claim 7 relates to the design of at least part of the pawl made of a plastic material.
- the carrier pawl preferably the entire carrier pawl, is made from a plastic material.
- the carrier pawl can also be designed at least in part from a metallic material.
- a bearing pin assigned to the pivot bearing of the Trä gerklinke is used as a crash barrier surface.
- the engagement surface of the pawl and the crash barrier surface are matched to one another in such a way that in the event of a crash an at least partial form fit between the two surfaces is possible. In this way, in the event of a crash, the grip surface of the pawl can be prevented from slipping off the crash barrier surface in a simple manner.
- a variant for the crash barrier surface that is particularly easy to implement in terms of manufacturing technology consists in that the crash barrier surface is connected to a strike plate of the motor vehicle lock or is even formed by this. In the latter case, it is conceivable that the crash barrier surface is provided by a bevel of the strike plate, so that the crash barrier surface can be implemented without additional components.
- the proposed solution can in principle also be applied to the blocking arrangement, as is proposed according to claim 12. As a result, the crash safety of the motor vehicle lock can be further increased with little effort.
- the invention is explained in more detail with reference to a drawing showing only one embodiment.
- 1 shows a motor vehicle lock according to the proposal with the latch in the main closed position in a perspective illustration
- FIG. 2 shows the motor vehicle lock according to FIG. 1 in a top view
- FIG. 3 shows the motor vehicle lock according to FIG. 2 in the event of a crash.
- the motor vehicle lock 1 shown in the drawing can be assigned to any locking element of a motor vehicle. In this respect, reference may be made to the general part of the description.
- the motor vehicle lock 1 is equipped with a lock latch 2 pivotable about a lock latch axis 2a, which can be brought into an open position (FIG. 2 in dashed lines) and at least one closed position (FIG. 2 in solid lines).
- the latch 2 can be brought not only into the main closed position shown in FIG. 2, but also into a pre-closed position, not shown. However, this is of subordinate importance for the proposed solution.
- the closed position is always the main closed position. All relevant statements apply accordingly to a possible pre-locking position.
- the latch 2 In the illustrated, assembled state, the latch 2 is in the closed position with a locking part 3, here and preferably a striker, in holding engagement. In the open position, the latch 2 releases the locking part 3.
- the motor vehicle lock 1 is arranged on the associated closure element, while the closing part 3 is arranged on the motor vehicle body. This can also be provided the other way round.
- the motor vehicle lock 1 has a locking mechanism 4.
- the locking mechanism 4 can be brought into a locking state in which it locks the latch 2 in the closed position. This is shown in the drawing.
- the locking mechanism Mus 4 can also be brought to a release state in which it releases the lock latch 2 in its open position. The release status is not shown in the drawing.
- the locking mechanism 4 has a locking pawl arrangement 5 with a locking pawl 7 mounted via a pivot bearing 6 for the locking engagement with the lock latch 2.
- crash locking surface 8 It is essential that a crash locking surface 8 is provided and that an engagement surface 9 of the locking pawl 7 comes into engagement with the crash locking surface 8 in the event of a deformation-induced yielding of the locking pawl 7 or its pivot bearing due to crash forces transmitted by the closing part 3, so that at least some of the crash forces are diverted via the crash barrier surface 8.
- high crash forces Ci, C2, C3, C4 act from the locking part 3 on the lock latch 2, which continue via the lock latch 2 and the pawl 7 and are derived from the crash lock surface 8.
- crash forces encompasses all forces and torques that are due to the interaction between the closing part 3 and the lock latch 2 in the event of a crash.
- the locking mechanism 4 further has a blocking arrangement 10 which is used to block the pawl arrangement 5 in the blocked state.
- the arrangement is such that the pawl arrangement 5 would leave the locked state, driven by the latch 2, immediately if the blocking arrangement 10 would not exert a blocking effect on the pawl arrangement 5.
- the blocking arrangement 10 has a first blocking lever 10a and a second blocking lever 10b, which form a toggle mechanism 11 for blocking the pawl arrangement 5 and are coupled together via a toggle joint 12.
- the drawing shows the locking mechanism 4 in its locked state.
- the blocking arrangement 10 can now be actuated in the course of an opening process in such a way that that the locking mechanism 4 is transferred from the locking state shown in the release state.
- the pawl arrangement 5 has, in addition to the pawl 7, a carrier pawl 13 which is pivotably coupled to the pawl 7 via a connecting hinge 14.
- the connecting joint 14 preferably provides the pivot bearing 6 of the pawl 7.
- the pawl 7 can be mounted on a pivot bearing fixed to the housing.
- the term “fixed to the housing” is always related to the lock housing 15.
- lock housing is to be interpreted broadly.
- the strike plate is here and preferably a plate made of high-strength steel that provides the pivot bearings for various lock components, in particular for the lock latch 2 and / or the carrier pawl 14.
- the locking pawl 7 and the carrier pawl 13 also form a toggle lever mechanism 16 via the connecting joint 14.
- the blocking arrangement 10 for blocking the pawl arrangement 5 in the area of the connecting joint 14, here and preferably via the connecting joint 14, is coupled or can be coupled to the pawl arrangement 5.
- the pawl 7 now has at least one locking surface 17 for at least one engagement surface 18 of the latch 2 at a point remote from the associated connecting hinge 14, the carrier pawl 13 being pivotable at a point remote from the associated connecting hinge 14, here and preferably based on the Lock housing 15 is fixed to the housing and is mounted via pivot bearing 19.
- the toggle lever mechanism 16 of the pawl arrangement 5 is designed in such a way that it would buckle upwards in FIG.
- the pivot bearing 6 of the pawl 7, in particular the connecting joint 14 between the support pawl 13 and the pawl 7, is preferably at least partially made of a plastic material. With a view to the representation according to FIG. 3, this also makes sense, since any deformation that is generated by possible crash forces leads to an engagement between the engagement surface 9 of the pawl 7 and the crash lock surface 8.
- part of the pawl 7 is made from a plastic material.
- part of the pawl 7 is then made from a metallic material and another part of the pawl 7 is made from a plastic material, in such a way that the crash forces are transferred via the crash barrier surface 8 essentially via the metallic part of the pawl 7, and not via the part of the pawl 7 made of a plastic.
- the carrier pawl 13, here and preferably the entire carrier pawl 13, can be made from a plastic material without the proposed crash safety being impaired. Additionally or alternatively, however, it can also be provided that at least part of the carrier pawl 13, preferably the entire carrier pawl 13, is made from a metallic material.
- the crash barrier surface 8 is part of a bearing pin 20, which is part of the pivot bearing 19 of the carrier pawl 13. This can be seen from the illustration according to FIG. 3.
- the illustration according to FIG. 3 finally shows that the engagement surface 9 of the pawl 7 and the crash barrier surface 8 are designed in such a way that they can be brought into engagement with one another at least partially in a form-fitting manner in the event of a crash.
- the form-fit is preferably made such that it acts transversely to the direction of the yielding of the pawl 7 or its pivot bearing 6 in such a way that the form-fit prevents lateral slipping transversely to the direction of the yielding of the pawl 7 or its pivot bearing 6. This is a particularly simple measure to further increase crash safety.
- This additional form fit can be seen in FIG. 3, an additional bulge 21 in the engagement surface 9 of the pawl 7.
- a crash barrier surface 8 that is particularly easy to implement consists in that the crash barrier surface 8 is connected to a strike plate of the motor vehicle lock 1 or is formed by it. As mentioned above, this leads to a particularly cost-effective design, in particular since no additional parts are required for the implementation of the crash barrier surface 8.
- a further Crashsperrflä surface 22 is provided and that an engagement surface 23 of the blocking arrangement 10, in particular of the first blocking lever 10a, in the event of a crash when the blocking arrangement 10 yields due to deformation, which is caused by the crash forces transmitted by the closing part 3 is, comes into engagement with the further crash barrier surface 22, so that at least some of the crash forces are diverted via the further crash barrier surface 22.
- the increased crash safety associated therewith can be achieved even if the first blocking lever 10a is made of a plastic material.
- one of the blocking levers of the blocking arrangement 10, here the second blocking lever 10b can be pivoted at a point remote from the knee joint 12, here and preferably with reference to the lock housing 15 fixed to the housing via a pivot bearing 24.
- the further crash barrier surface 22 is part of a bearing pin which is part of the above pivot bearing 24 of the second blocking lever 10b.
- the engagement surface 23 of the first blocking lever 10a and the further crash barrier surface 22 are designed in such a way that in the event of a crash, they can be brought into engagement with one another in a form-fitting manner, at least in part. In this respect, the engagement surface 23 is also prevented from slipping off the further crash barrier surface 22.
