Description

Motor vehicle door lock

The invention relates to a motor vehicle door closure with a locking mechanism up-setting at least a rotary latch with a load arm and a detent arm and a pawl, wherein the rotary latch is mounted pivotably about a first pivot axis and the ratchet is rotatable about a second rotational axis, wherein the locking pawl, the catch is able to make in a rest position, in particular a main latching position.

The invention includes both in vehicles usual pivotable flaps or doors as well as sliding doors or movable (rear) flap or (motor) caps or trays. The measures provided for in today's motor vehicles rotary latches have damping elements, in particular of contact points to a hard stop of the catch. Further, damping elements are provided for impingement of a lock holder, the lock holder is usually arranged on the motor vehicle. DE 10 2006 028 423 A1, for example, shows a rotary trap with integral damping elements for a Bouncing pawl and the lock holder.

It is also known to provide a stop buffer for the lock pawl so that the pawl is limited in its pivoting-out and arrives at the stop buffer during a pivoting out of the opening position into a locking position into abutment. The bump stop for the pawl is known to be formed on a lock housing of the motor vehicle door lock. From DE 10 2006 025 719 A1 it is further known to bump stop for the pawl in the form of a motion damper provided so that the impacts of the pawl is noise reduced at the motion damper. A problem that arises in the development of buffer devices of motor vehicle door locks, a structurally favorable solution for forming a damping element is found. Further development of noise upon impact of the pawl against the damping element on the rotary latch and / or on the stop buffer for the latch on the lock housing optimized to be. Furthermore, an arrangement of the stop buffer for the lock pawl is structurally complicated. A fixation of the bump stop in the lock housing requires, for example, a bending of a portion in the lock housing to form an exception for a stop buffer, so that the receptacle in the lock housing can then take the stop buffer for the lock pawl. In a region of the bend of the receptacle an opening in the lock housing is then created, wherein the opening of dust and / or water allows inclusions.

As a result of dust and water effects a proper lock opening is then no longer guaranteed. This then means that the catch can no longer functional reach to their original position and / or its opening position.

The invention is based on the object to provide an improved Gesperrefunktion in a motor vehicle lock, and in particular external influences such as dust inclusions or prevent ingress of water. Moreover, it is an object of the invention to provide a secure lock opening over the entire life of the vehicle while reducing a construction effort. Moreover, it is an object of the inventions dung a noise-reduced and inexpensive lock opening device for motor vehicle door lock to provide. The object is achieved according to the invention by the features of independent patent claim 1. Advantageous embodiments of the invention are specified in the subclaims. It should be noted that the constricting in folic described embodiments are not limited to, any possible variations of the features described in the description and the dependent claims it is rather possible.

According to the patent claim 1, the object of the invention is achieved by a motor vehicle door closure with a locking mechanism comprising at least a rotary latch with a load arm and a detent arm and a pawl, wherein the rotary latch is mounted pivotably about a first axis of rotation and rotatably supported, the pawl around a second axis of rotation is, wherein the pawl may comparable to hold the catch in a detent position, in particular a main catch position, wherein the pawl by means of at least one buffer element in a latching position, in particular main latching position can be transferred.

The inventive design of a motor vehicle door lock, the possibility is created, the catch in a structurally simple manner pre- preferably from the opening position into the Vorrast- or main latching position to convert. It is advantageously provided that the buffer element or damping member, the pawl into the pre-locking position and / or into the main latching position. have the load arm and the capture arm of the catch form a fork-shaped inlet opening or inlet opening. The inlet opening receives a lock holder upon closing of the vehicle door located on the motor vehicle in an opening position of the motor vehicle door lock. The lock holder can position to rotate the rotary latch during the closing of the door from opening until the pawl in the locked the catch a Vorrast- or main latching position. In this locking position of the lock holder remains in the inlet opening of the catch, to opening of the door is initiated.

In an advantageous embodiment of the invention, the buffer member is formed on the rotary latch. The buffer element or damping element may be located on the rotary latch in a positive and / or material-locking and / or force-locking. For example, the buffer member may be integrally formed on the rotary latch, glued or it may be any other means may be used which is suitable in order to exclude the buffer element functionally reliable on the rotary latch form. By constructing the buffer member on the rotary latch can be dispensed, for example, one, two or more further buffers advantageously. This is particularly an advantage if, for example, the buffer is added in the lock case, and thus openings in the lock casing and / or housing of the lock are provided which are used, for example, indirectly, for the storage of or the buffer. can then be dispensed with these openings.

It is understood that the material of the buffer element requirements of impact resistance and / or preventing noise generation during the guiding and / or bouncing of the pawl will meet. It is advantageously an elastic and simultaneously impact-resistant material, such as plastic used. Further, the buffer material is selected such that wear between the rotary latch and the pawl is reduced. The conventional plastics used in the jacket of the rotary latches can thereby be used in an advantageous manner.

In an advantageous embodiment of the invention, the buffer element is integrated in a casing of the rotary latch. The buffer material can thus be part of the jacket of the catch. It is such a structurally simple manner, the buffer member on the rotary latch formable. The buffer member may be integrated into an existing motor vehicle door latch, consequently, wherein an additional assembly work can be omitted. In this case, the buffer member can be formed directly and integrally with the casing of the rotary latch, which in turn is an advantage. extending the buffer member along a contact region between the rotary latch and detent pawl so results in a further advantageous embodiment of the invention. The pawl is located at least in a closing of the Gesper- res spring biased almost continuously against the rotary latch on. Only at the moment of incidence in the Rastpostion the pawl releases the short term of the rotary latch, wherein the pawl drops into a detent position. The continuous concern and / or incidence of the catch on or against the catch allows here a damped guiding the pawl and especially quiet stopping. the leadership of the ratchet can be influenced in addition from the guidance along the catch on the buffer element. Depending on the elasticity of the contact portion a more or less silent guiding can be achieved.

In a further embodiment, then yields an advantage when the buffer member is formed of a recess in the casing. A unmit- nent formation of the buffer element in this case allows cost-effective manufacture and shaping of the buffer element. If the rotary latch for example provided with a plastic sheath, the buffer member may be molded directly into the shell during the plastic injection process in the sheath or inserted. In this way, ease of manufacture is guaranteed and at the same time are almost any shape of the recesses that are feasible in the plastic injection process to produce. The recess may be, for example, slot-shaped, round, angular and / or oval. Of course, two or more recesses may be provided, which follow one another or are arranged as beispiels- nested. Is at least one further buffer element is present, results in a further embodiment of the invention. The buffer members are preferably mounted in the areas on the rotary latch, which are located in direct engagement with the pawl, so a direct reducing an input, for example, can be achieved event noise. However, it is according to the invention also conceivable that two or more buffer elements are arranged one behind the other, so that by means of the buffer elements is achievable an indirect influencing of guiding or abutment of the pawl of the rotary latch. Here may men com- different shapes or geometries in the design of the buffer elements are used. Also, it is envisaged that different shapes or geometries are combined, a circular recess with a circular recess which can for example be at least partially enclosing the recess are combined. In a further advantageous embodiment, the additional buffer member is formed in the region of a main latching position in an engagement portion between the pawl and the catch. The formation of at least one buffer element in the region of the latching positions of the rotary latch and detent pawl has the advantage that a defined, low-noise incidence of the pawl can be achieved in the locking position. The locking incident sound is substantially reduced, whereby in the latched position the buffer element additionally fulfills a Lagepufferung. In the locking position, such as the main catch and the preliminary catch, the buffer member thus has a dual function, so the engagement of the pawl on the one hand buffered thus realizing low noise are, and on the other hand, the buffer member can serve as a system buffer. Thus, it is possible for example to dispense with separate buffer elements for storing and / or buffering of the catch. Components are saved thus, leading to a cost reduction in terms of components and assembly. Is the at least one further buffer element on a line extending along the pawl recess is formed, this results in a further advantageous embodiment of the invention. It is conceivable according to the invention therefore that two, for example one after the other, extending along the contact visit Reich recesses are present in the catch. By extending along the rotary latch recesses which guide and system behavior of the pawl can be influenced and it can be reduced noises. In particular, it is thus possible that the pawl in the event of a lifting of the catch always comes to a versehe- machines with a buffer area of ​​the catch in contact. Buffer surface area means the area of ​​the catch in which a buffer member is disposed, wherein an interaction between the rotary latch, buffer element and the pawl is carried.

Preferably, a buffer member between the first position and the main catch is arranged on the rotary latch and preferably arranged extending portion of the rotary latch in a down aligned along an area of ​​contact with the ratchet surface. In other words, the buffer member is preferably in a contact area of ​​the pawl with the catch and along the catch. Here, the buffer member may be formed from two or more recesses.

One, two or more openings to form a buffer member may be arranged also in the area of ​​the main catch, so that a combined buffer element can be formed. Combined means that different geometric shapes of recesses, such as elongate, curved, round, oval, square, etc. are conceivable. Also, the recess does not extend through the entire width of the catch through and may for example be formed as a blind hole.

In a further embodiment of the invention is then obtained an advantage if the other buffer element is formed on the rotary latch. It can be formed in the region of the primary position, a first buffer element in the region between the first position and the main catch and a second buffer member. The buffer elements are always arranged so that in a first position and is the main catch the pawl with the stop surface of the catch and the buffer member in engagement. The pawl is thus in the locking positions on the rotary latch, while the buffer member.

Is an incident depth of a pivotal movement of the pawl in the direction of the rotary latch can be limited by abutting on the buffer element of the catch, so there is a further advantageous embodiment of the invention. The blocking pawl is situated in the one or more locking positions on the rotary latch and the buffer member. The incident depth of the pawl in the locking position is limited at from the buffer element. The buffer element thus a further object occurs, namely, that the buffer member serves as a limitation of the depth of incidence, whereby the interplay or cooperation of the pawl and the rotary latch can be defined. The buffer member thus acts as limiting means to the function of the locking mechanism from. This can be an advantage in particular if the resultant from the interaction of torque can be influenced and / or adjustable by means of the incident depth. It can set an opening or closing moment in the locking mechanism consequently, depending on definable incident depth of the pawl.

In a further advantageous embodiment of the invention is then obtained an advantage if an arm of the pawl second one hand at a first catch surface of the catch and on the other hand, to a first buffer element of the rotary latch or the arm of the pawl on the one hand at a second catch surface of the catch and on the other hand, on a able to bear buffer element of the catch. The combination of concern at the buffer element and catch a defined, noise-reduced and defined incidence of the locking pawl in a locking position is attainable. Advantageously, it may also be, and represent an embodiment of the invention, when the pawl is guided by the rotary latch in such a manner that the locking pawl preferably continuously rests on the rotary latch. Due to a concern, and particularly a concern in a buffer area a noise of the locking mechanism can be reduced. In particular can be dispensed with vehicle lock by the formation of buffer elements on the rotary latch on other buffer and / or stops in the force.

The invention with reference to the accompanying drawings is illustrated by a preferred embodiment of calculations. However, the principle is that the embodiment does not limit the invention but merely constitutes an advantageous embodiment. The features illustrated may be performed individually or in combination singly or in combination with other features of the description and the claims. It shows:

Fig. 1 is a plan view of the components of the invention of the motor vehicle door latch in the main catch position.

Fig. 2 is a plan view of the components of the motor vehicle door lock according to the invention in pre-locking position.

Fig. 3 is a plan view of the components of the invention of the motor vehicle door lock in the opening position.

1 shows a locking mechanism of a motor vehicle door lock 1, only partially shown in a plan view of a, is located in a main latching position motor vehicle door lock 1 is shown. The locking case has a catch 2 and interacting with the catch 2 pawl 3, wherein the locking mechanism is in this view in a main locking position. The catch 2 is pivoted about a pivot axis 4 and the pawl 3 is pivotally mounted about a rotational axis. 5 An unillustrated lock holder, which is arranged for example on a vehicle body is held in the main locking position in a recess 6 of the rotary latch. 1 The locking mechanism 2, 3 is mounted on a lock housing 7, which is also be referred to as a lock case by means of bearing bolts, wherein the bearing pin, the pivot axes 4, 5 form for the catch 2 and the pawl. 3 A stop 8 for the catch 2 is also provided in the form of a Hauptrast- and / or Überhubpuffers 8 and may for example be added to the lock case 7, the catch 2 comes to the stopper 8 in its main latching position to rest or to stop.

The catch 2 is main latching position shown 1 clockwise from its illustrated in Fig. In an open position, as shown in Fig. 3, be pivoted. In the opening position, the catch 2 releases the lock holder, so that the vehicle door can be manually and / or electrically openable.

The receptacle 6 of the rotary latch 1 is formed in particular of a fork-shaped inlet opening 9 for the lock holder, the fork-shaped inlet opening 9 is formed by a catch arm 10 and a load arm 1 1 of the rotary latch. 2 The load arm 1 1, the catch 2 is in the opening position above an inlet opening 21 in the lock housing 7, so that the lock holder can pass unimpeded from the inlet opening 9 of the catch 2 into or out. The catching arm 10 of the catch 2 is deflected in the open position of the catch 2 in such a way that the lock holder can impinge during a closing operation of the vehicle door on the catch arm 10 degrees. During the closing operation of the vehicle door of the catching arm 10 catches on the lock holder. The catch 2 then pivoted due to the clamping force with which the vehicle door will be concluded and is thus transferred to the catch arm 10 in the illustrated embodiment, in the counterclockwise direction until the stop 8 for the catch 2. The pivotal movement of the catch 2 from its opening position in the main latching position is thus collected by the stop 8 or decelerated.

The load arm 1 1, the catch 2 then maintains the lock holder securely in a Vorrast- and / or main latching position. In the embodiment shown in FIG. 1, main detent position, the catch 2 is spring biased against, a spring 12, in particular a leg spring, the catch 2 biases forward for the catch 2 in the clockwise direction. Which is also spring-biased pawl 3 is locked, the rotary latch 2 in the Vorrast- and / or main latching position, wherein a spring 13 biases the pawl 3 for the pawl 3 in the counterclockwise direction.

The biased counterclockwise pawl 3 holds the catch 2, like, latched in the pre-locking position or the main latching position. In the pre-locking position, an arm 14 is the pawl 3 at a first latching surface 15 of the catch 2 to abut and such keeps the rotary latch 2 in its pre-locking position (see Fig. 2). In the main latching position of the locking pawl 3 holds latched to a latching surface 16 by means of its arm 14 the rotary latch. 2

Advantageously, the biased pawl 3 can be guided by means of the rotary latch. 2 The pawl 3 is passed through the rotary case 2 such that the pawl 3 is preferably applied due to their spring bias through on the rotary latch. 2 There is a buffer area 17, 18 on the catch 2 for the leadership of the pawl 3 ren provided. In particular, the pawl 3 is connected via its arm 14 can be guided along the catch 2, that is, the pawl 3 is guided spring-loaded along the rotary latch. 2

The arm 14 of the pawl 3 is in the pre-locking position on the one hand to the first locking surface 15 of the catch 2 and the other hand to a first buffer member 17 of the rotary latch 2 as shown in Fig. 2. In the main latching position of the arm 14 is the pawl 3 on the one hand against the second locking surface 16 of the catch 2 and the other hand to a second buffer member 18 of the rotary latch. 2

Here lies a latching surface 19 on the arm 14 of the pawl 3 in the pre-locking position on the locking surface 15 of the rotary latch. 2 Simultaneously, a contact surface 20 is located on the arm 14 of the pawl 3 on to the first buffer element 17 of the catch 2, then the ratchet is in a pre-locking position, as shown in FIG. 2

If the ratchet 2 is now caused to ken verschwen- into its main latching position, the pawl 3 is guided over its contact surface 20 along the first buffer member 17 of the rotary latch in the direction of the main latching position. The contact surface 20 of the pawl 3 can during the swiveling from the pre-locking position into the main detent position preferably continuously abut 3 to the first buffer element 17 of the rotary latch.

The pawl 3 is up in the main latching position feasible, wherein the contact surface of the pawl 3 comes to rest in the main catch position on the second cushion member 18 of the catch 2 twentieth At the same time, the pawl 3 is locked, the rotary latch 2. The latch 3 is able to pivot from the first buffer member 17 of catch 2, because of their spring bias counterclockwise to the second buffer member 18 of the rotary latch. 2

The second cushion member 18 has a smaller radial distance relative to the radial distance of the first buffer member 17, starting from the axis of rotation 4 of the catch 2. an array of the buffer elements 17, 18 to each other on the rotary latch 2, the incident depth of the pawl is determined by the first buffer member 17 18 to the second buffer element Advantageously, the depth of incidence selected such that contact between the abutment face 20 of the pawl noise is reduced to the second buffer element 18. 3 A depth of incidence of the locking pawl 3 in the pre-locking position is also advantageously selected so that an impact noise upon impact of the abutment surface 20 of the pawl is noise-optimized 3 on the first cushion member 17 of the rotary latch. 2 Further determined over the depth of incidence of the pawl 3 from the opening position to the pre-locking position and subsequently in the main latching position of a change in load exerted on the locking pawl. 3 By the lowest possible load change of the pawl 3, the acoustics can be optimized in an advantageous manner. The lowest possible load change of the pawl 3 is realized in which the pawl 3 is applied continuously as possible on the rotary latch. 2 Further, for the lowest possible height difference between the first and second buffer member 17 to provide 18th Due to the inventive design of the catch 2 with buffer members 17, 18 advantageously guiding the pawl 3 along the catch 2 can take place. Here, the buffer or guide elements 16, 17 integrally conformable to the rotary latch. 2 For example, the catch 2, as provided in the embodiment, have a plastic coating 22nd The buffer or guide elements 17, 18 are formed as recesses or through-holes in the shell 22 of the rotary latch. 2

Suitable plastics for the shell 22, the known plastics can be used for a rotary latch casing 22nd Here, the shape, position and dimensions of the buffer and / or guide elements 17, 18 is selected such that a guiding and locking of the locking pawl 3 in the locking positions, first position 23 and main latch 24, optimized for noise that is attenuated occurs.

A reinforcing plate 25 is supported, leads and connects the bearing pins 4, 5. In particular, the combination of the reinforcing plate 25 and the buffer and / or guide elements 17, 18 results in an advantageous embodiment of the invention. On one hand, the pawl is guided along the rotating latch 2, and at the same time the catch 2 undergoes a guide by the reinforcing plate 25. Accordingly, it is a very precise and definable guiding of the pawl 3 ermöglichbar. The guiding can be, for example, by forming the overall ometrischen dimensions of the buffer and / or guide elements 17, 18 significantly affected and hence are designed adjustable.
