Description

An automobile door handle

The invention relates to a motor vehicle door handle with a handle which is agerable from a rest position in a ßetätigungsposition s / e, wherein a arranged on the back of the handle handle hook is kinematically coupled in the assembled state with a lever, wherein the lever during the displacement of the rest position acts in the operating position directly or indirectly on a motor vehicle door lock and wherein the lever is held by means of a locking element in a preassembly position, as long as the handle hook is not completely inserted its mounting position.

Such motor vehicle door handles are known. For mounting the handle, it is also known to bring the lever, with which the back arranged on the handle grip hooks during assembly to bring in a pre-assembly.

From DE 101 03 846 A1 motor vehicle door handle is known with a bracket attachable in an opening of the door and thereignable handle, wherein the console is associated with a handle coupled to the transmission element in the form of a pivot lever, for transmitting the pivoting movement of the pivot point of the handle remote extension of the handle on a closing member. It is envisaged that the transmission member is held spring biased in a rearward position before mounting the handle, this repealed by the pivoting of the extension into the console

CONFIRMATION COPY is, whereby the transmission member is pre-displaced by the spring and the transfer member associated driving projection enters an opening of the extension. From DE 199 40 379 C2 is motor vehicle door handle with a mounted on the back of the door carrier, with a arranged on the side of the door handle, which can be transferred from its rest position on the door by a pulling or folding movement in an operating position with respect to the lock members Known, wherein the handle passes through located at both ends of the handle door openings and at least one handle end of the handle is connected to a pivotally mounted on the carrier lever and the connection of the handle end on the lever is made possible by one of the door recess near Ausschwenklage of the lever, and with a plug-in from the show side of the door in the carrier housing, wherein the housing is fastened in the insertion on the carrier and having a lock cylinder acting on the lock, wherein between the carrier and the lever automatically between an active holding position and a ineffective release position reversible retaining element is arranged, wherein when mounting the carrier on the door, the holding element for connecting the handle is initially in its holding position, where it holds the lever in its swung-out position, and wherein the housing when inserting into the carrier, the holding element automatically its release position transferred, where the lever is released. A disadvantage of the known motor vehicle door handles is that the serving as a transmission link lever is released accidentally before final assembly of the handle hook from the pre-assembly, whereby an assembly of the handle hook and thus a mounting of the entire vehicle door handle is impossible with the result that removes all modules again and need to be prepared for re-assembly, which means a considerable time and assembly costs. The object of the invention is therefore to develop a motor vehicle door handle of the type mentioned in such a way that this allows easier final assembly of the handle and thus the entire vehicle door handle. This object is achieved by a motor vehicle door handle according to claim 1. Advantageous developments of the invention are specified in the subclaims.

Particularly advantageous in the motor vehicle door handle with a handle which is displaceable from a rest position to an actuating position, wherein a arranged on the back of the handle handle hook is kinematically coupled in the assembled state with a lever, wherein the lever during the displacement of the rest position in the operating position acts indirectly or directly on a motor vehicle door lock and wherein the lever is held by means of a locking element in a preassembly position, as long as the handle hook is not fully inserted its final assembly position, it is that the locking element of the handle hook when it is inserted into its mounting position of the locking position in a Release position is relocated.

The essence of the invention is thus the arrangement of a locking element which locks the lever in the preassembly, wherein the locking element is released from the handle hook when it is inserted into the final mounting position of the handle hook and pivoted into the release position. Conversely, accidental release is impossible. The locking element is arranged such that a release of the locking element is possible only by the handle hook in its introduction into the final assembly position. This means that the lever is held in the preassembly position and can not be accidentally released from this preassembly position, as long as the handle hook is not placed in its final mounting position, in which it engages in its final mounting position on the lever. After complete insertion of the handle hook in the mounting position For example, the grip hook can be connected directly or indirectly to the deflection lever by means of a screw connection or the like, so that the grip hook is kinematically coupled to the deflection lever in the mounted state.

By the term final assembly position or final assembly position is meant that position of the handle hook relative to the bell crank in which the kinematic coupling between the handle hook and the bell crank can be made by screwing in a fastening screw and / or inserting an axis coupling the components, or the like; according to the position which the handle hook and the lever have after completion of the assembly of the motor vehicle door handle to each other.

By the term of the rear side of the handle is meant that side which in the mounted state is rear seen by a user of the motor vehicle door handle, while the front side faces the user. In the assembled state, the rearwardly arranged handle hook engages through an opening in the motor vehicle door, while the handle is arranged so that it can be grasped by a user.

The locking element is particularly preferably a rocker which protrudes into the installation space for the grip hook in the locking position of the rocker and is thereby displaced from the locking position into the release position such that the front end of the grip hook rests on the rocker and the rocker during Insertion of the handle hook in its final assembly position pivoted from the locking position to the release position.

The locking element may thus preferably be a rocker, which is thereby displaced from the locking position to the release position, that the front end of the handle hook runs onto the rocker and the rocker during insertion of the handle hook in its mounting position from the locking position to the release position pivoted. This rocker can be formed by a punched out of sheet steel part. Preferably, the two arms of the rocker are not aligned, but rather can the rocker have a bend between the two arms of the rocker. Such a bend causes the locking arm forming the first arm of the rocker, which engages behind an undercut, for example, with a hook or the like, in the locking position parallel to the insertion of the handle hook, while the other arm of the rocker angled into the installation space and thus in the Plug-in channel of the handle hook protrudes, so that this second arm of the rocker is urged by the handle hook when it is inserted into the mounting position of the handle hook to the side, causing the rocker pivoted about its axis of rotation and the lock is released.

The lever is in the assembled state as a transmission member for transmitting the movement of the handle for opening the vehicle door by a user on the vehicle door lock, whereby in the unlocked state of the lock, the lock is opened. The reversing lever is indirectly or directly coupled to the motor vehicle door lock.

Particularly preferably, the rocker serving as a locking element in the pre-assembly position engages behind an undercut and / or a latching lug of a stationary component of the motor vehicle door handle and is displaced by the handle hook in the mounting position to the release position during the insertion of the handle hook.

The fact that the locking element engages in the pre-assembly an undercut of a fixed component of the motor vehicle door handle, the lever is secured in the pre-assembly and held reliably.

In a preferred embodiment, a hinge is pivotally mounted on the lever, in which the handle hook engages in the assembled state, wherein the rocker serving as a locking element is arranged pivotably about an axis of rotation on or in the joint. The joint, which engages in the assembled state of the handle hook of the handle, allows the transmission of the movement of the handle on the acting as a transmission link lever. The joint serves to couple the grip hook and the reversing lever, since the pivot point of the movements of the handle does not have to coincide with the pivot point of the reversing lever. Therefore, an articulated connection between the handle hook and lever is provided. As an alternative to a joint as a separate component, the grip hook can also be coupled to the deflection lever, for example, by means of an axis which extends through the grip hook and the deflection lever.

In a particularly preferred embodiment, the rocker serving as a locking element on a run-on slope, which protrudes into the mounting position for the handle hook in the locking position of the rocker, so that a chamfer at the front end of the handle hook runs onto the run-on slope of the rocker and pivots it during insertion of the handle hook ,

The locking element in the form of an arranged on the lever rocker or in the form of a rotatably mounted on the lever pivot joint rocker is thus displaced by the release position that the handle hook runs on the rocker and the front end of the handle hook an arm of the rocker for Side presses, so that the rocker is pivoted about its articulation point on the joint, whereby the locking member is pivoted from its locking position to its release position and thereby the lever secured in the preassembly position is free to move.

The locking element is thus designed as a arranged on the hinge about a rotation axis pivotable rocker. As long as the locking element is engaged and locks the lever with the pivotally mounted thereon hinge in the preassembly, is an arm of the rocker, which has a run-in, provided in the handle hook installation space, so that the handle hooks when inserted into the mounting position in the Joint runs onto the run-on slope and acts on the rocker by the armature of the rocker forming the run-up slope pushed away by the handle hook and thereby the rocker is pivoted about its axis of rotation. As a result of the pivoting of the rocker about its axis of rotation in turn arranged on the other arm of the rocker an undercut of a fixed component of the motor vehicle door handle engaging behind hooks, so that the bellcrank and optionally pivotally mounted thereon joint are released from the pre-assembly. However, this release of the reversing lever from the preassembly position is due to the design of the locking element only after the complete insertion of the handle hook in the final assembly position.

Preferably, the lever and / or the handle is / are spring loaded in the direction of the rest position. By such a spring load in the direction of the rest position of the lever and the kinematically coupled to the lever lever handle are simultaneously displaced to the rest position corresponding to the closed position of the motor vehicle door handle, unless a user pulls on the handle and the handle in the operating position corresponding to the opening position of the motor vehicle door handle relocated. Particularly preferably, the reversing lever via a push rod and / or a pull rod and / or a cable on the motor vehicle door lock, thereby causing its opening when not locked vehicle door lock. The indirect or direct coupling of the lever and motor vehicle door lock can thus be realized in many ways, in particular by a combination of push rod and / or a pull rod and / or a cable, which is also referred to as a Bowden cable.

In a particularly preferred embodiment, the lever on at least one locking element, which comes in case of an external pulse due to a side impact with an accidental lock in engagement and a Displacement of the bellcrank and the handle blocked from the rest position to its operating position.

It is a so-called crash barrier, which takes effect on the occurrence of a large pulse as a result of an impact and blocked the handle, so that the vehicle door is not accidentally opened by the impact pulse that the handle due to its inertia from the rest position out in the operating position is displaced or thrown. Accordingly, the moving masses, any spring constants when a spring load and the ease of the joints of the entire system and in particular the crash barrier are chosen so that when an impulse, for example as a result of accidents, the crash barrier is so smooth and has a correspondingly smaller inertia that First, the crash barrier engages the detent member on the bell crank and blocks both the bell crank and the handle before the handle could be displaced out of its rest position due to the momentum. By this accident insurance opening of the door due to an impact or other accidents is reliably prevented.

Preferably, the locking element is positively fixed to the lever or to a pivotally mounted on the lever pivot, in particular in the form of a rocker which engages by means of pins in corresponding receiving holes in the lever or in the joint and is pivotable about the axis passing through the pin axis.

Preferably, a hinge is rotatably mounted on inwardly projecting pins of two arms of the reversing lever. In this joint of the grip hook engages in its final assembly position in the joint.

In the assembled state, the handle hook is preferably fixed by means of a screw connection to a pivotally mounted on the bell crank joint. A screw connection has the advantage that this can be solved easily and in particular non-destructive. Alternatively, other connection techniques can be used.

Fig. 12 shows two plan views of the handle hook used in the joint before and after the mounting of the fastening screw.

Fig. 1 shows a perspective view of the handle 10 of a motor vehicle door handle. At the left in Fig. 1 end 15 of the handle 10, the handle is inserted into a corresponding corresponding receptacle and is pivoted upon actuation of the handle 10 by a user to an extending in the region of the left end 15 of the handle 10 axis from the rest position out.

On the back of the handle 10 of the handle hook 11 is arranged, by means of which the handle 10 engages a gate, not shown in FIG. 1 on the motor vehicle door. The handle hook 11 engages in the joint 20, which is pivotally mounted on the reversing lever 30. The handle hook 1 is thus kinematically coupled to the reversing lever 30 via the joint 20. In the position shown in Fig. 1 are handle 1 and lever 30 in the deflected out of the rest position operating position. Of the reversing lever 30 is shown in the illustration of FIG. 1 only a section. The lever itself is in turn articulated to a in Fig. 1 not dargstellten carrier. Upon displacement of the handle 10 by a user from the rest position to the actuation position is thus due to the kinematic coupling of the handle 10 and lever 30 via the joint 20, a deflection of the reversing lever 30 in the operating position. The reversing lever 30 itself is in turn connected via a cable pull, not shown in FIG. 1, to a motor vehicle door lock of the motor vehicle door. If the door lock is not locked, the operation of the Handle 10 and thereby caused deflection of the reversing lever 30, the door lock and thus the vehicle door open.

Since the articulation point of the handle 10 in the region of the left in Fig. 1 end 5 and the pivot axis of the reversing lever 30 at a distance parallel to each other, the kinematic coupling between the handle 10 via the handle hook 11 and the lever 30 by means of the joint 20, which is pivotally mounted at the front end of the reversing lever 30. For this purpose, the grip hook 11 engages in the joint 20 and is secured in the joint by means of a fastening screw.

The handle hook 11 is made in the illustrated embodiment of polypropylene. The joint 20 and the reversing lever 30 are die-cast parts made of a die-cast zinc alloy. Alternatively, the joint may also be made of plastic.

In Fig. 2 is an enlarged view of the handle hook 11 is shown with the bore 12. The bore 12 is provided so that after mounting a fixing screw can pass through the hole 12 and the handle hook 11 defines in the joint 20.

3 shows a perspective view of the steel rocker 40, which serves as a locking element and is inserted into the joint 20. The joint 20 shown in perspective in Fig. 3b has a circular passage 21 which is aligned in the final assembly position with the bore 12 in the handle hook 11, so that the handle hook 11 within the joint 20 with the holes 12 in the handle hooks 11 and 21 in Joint 20 thorough fastening screw can be fixed. In Fig. 3a is a perspective view of the steel rocker 40, which is inserted into the joint 20 of FIG. 3b, shown. The steel rocker is formed in the illustrated embodiment by a high-strength chromium nickel steel. The steel rocker 40 in turn also has a circular passage 41 for the fastening screw, which in the Final assembly position the handle hook 11 passes through the bore 12 and the joint 20 and arranged in the joint 20 steel rocker 40 and the components coupled together. The steel rocker 40 forms the locking element. The steel rocker 40 has recesses 42, by means of which the steel rocker 40 engages over corresponding pins within the joint 20, so that the steel rocker 40 is pivotable about these pins engaging in the recesses 42 within the joint, that is, the center of the pins, the axis of rotation the steel rocker 40 forms. Further, the steel rocker 40 has hooks 43, which engages in the pre-assembly locking latches on the support of the motor vehicle door lock and thus secures the joint 20 and the lever in the preassembly, as will be explained below.

On the sides of the joint 20, of which in the perspective view of FIG. 3b, only one is visible, the joint 20 slots 22, which serve the joint 20 on the two projecting arms 31, 32 of FIG Turning lever 30 on the on the projecting arms 31, 32 inwardly projecting pins 33, 34 put on, so that the joint 20 is pivotable relative to the lever 30.

The reversing lever 30 is shown in perspective in Fig. 4. Visible are the two arms 31, 32, projecting on the inner sides of the pins 33, 34 for receiving the joint 20. Laterally, the lever 30 has two pins 36, 37, which form the axis of rotation of the reversing lever 30 about which the lever 30 is pivoted upon actuation of the door handle.

The reversing lever 30 also has circular holes 35 which serve to couple the reversing lever 30 to a Bowden cable, not shown, via which the reversing lever 30 is coupled to the motor vehicle door lock and, when the vehicle door lock is not locked, causes it to open when actuated. The bore 35 serves to receive a Bowden cable. About the pins 36, 37 of the lever 30 is fixed to a support, not shown, of the motor vehicle door lock about the axis passing through the pins 36, 37 axis. At the front end, the reversing lever 30 has two projecting arms 31, 32, which serve to receive the joint 20. For this purpose, the arms have inwardly projecting pins 33, 34, over which the joint 20 is pushed with the oblong holes 22, so that the joint 20 relative to the reversing lever 30 is pivotable. Furthermore, the reversing lever 30 has a latching element 38, which can engage with an accident safeguard (not shown in the figures) and block the reversing lever 30. Upon occurrence of a strong external pulse on the vehicle door handle, for example due to a side impact, the mass of the crash barrier against the mass reversing lever 30 and the coupled thereto handle 10 is selected so that the crash occurs due to the external impulse, as occurs in a lateral impact on the motor vehicle , is deflected from the rest position and with the locking element 38 on the reversing lever 30 is engaged, whereby both the lever 30 and the handle 10 is blocked against displacement in the operating position. The locking element 38 thus serves as accident protection to avoid that the vehicle door could jump open as a result of a side impact.

Fig. 5 shows the pre-assembly of the joint 20. In the joint 20, the fastening screw 50 is inserted, as shown in Fig. 5c. The fastening screw 50 shown in perspective in FIG. 5a has a first region 51 with a right-hand thread. In the illustrated embodiment, the portion 51 is a M5 right-hand thread. Furthermore, the fastening screw 50 has a further threaded portion 52 with a left-hand thread. In the illustrated embodiment, the portion 52 is an M4 left-hand thread. The fastening screw 50 is inserted into the joint 20 as shown in FIG. 5 c and subsequently secured with the lock nut 53. When the locking nut 53 is in the illustrated Embodiment to a nut with a M4 left-hand thread, which is screwed onto the left-hand threaded portion 52 of the fastening screw 50 and the securing of the fastening screw 50 in the joint 20 is used. Further, the lock nut 53 forms a stop shoulder after completion of assembly. The locking nut 53 is in turn secured by screwing on the left-hand threaded portion 52 of the fastening screw 50 by deformation of the thread itself.

In the perspective view of Figures 5c and 5d are recognizable bearing pin 23 in the interior of the joint 20. On these bearing pin 23, the steel rocker 40 is pushed with their corresponding recesses 42, so that the steel rocker 40 about the bearing pin 23 around within the joint 20 pivotally is. The bearing pin 23 thus form the axis of rotation of the steel rocker 40th

The insertion of the steel rocker 40 in the joint 20 is shown in Fig. 6a. For this purpose, the steel rocker 40 is inserted as shown by the arrow 60 from below into the joint 20 upwards and then displaced forward, so that the recesses 42 of the steel rocker 40 engage over the arranged within the joint 20 pin 23, so that the rocker 40 within of the joint 20 is pivotally mounted around the pins 23 around. Fig. 6b shows a perspective view of the joint 20 with inserted therein steel rocker 40 and preassembled fixing screw 50. The insertion of the joint 20 with therein pre-mounted steel rocker 40 in the lever 30 show the figures 7 and 8. For this, the inverted joint 20 as shown by the dashed arrows in Fig. 7 shown from below with its laterally arranged long open slots 22 on the pins 33, 34 pushed on the two protruding arms 31, 32 of the reversing lever 30 and then as shown in Fig. 7b by 180 ° in its actual orientation pivoted relative to the reversing lever 30. 8 shows the preassembled joint 20 on the reversing lever 30 in a perspective view. Fig. 9 shows side views of the reversing lever 30 and the joint 20 with the steel rocker 40, which serves as a locking element, in the preassembly position in Fig. 9a before the introduction of the handle hook 11 and in Fig. 9b after the introduction of the handle hook 11 in the final assembly position in The joint 20. In Fig. 10 are sectional views corresponding to the line AA of the bell crank 30 and the joint 20 with the pivotally mounted in the joint 20 steel rocker 40 in the pre-assembly of FIG. 10a before the introduction of the handle hook 1 and in Fig. 10b after the introduction of the handle hook 11 shown in its final assembly position in the joint 20, by means of which the operation of the locking element in the form of the steel rocker 40 will be explained.

9a and 10a, respectively, the pre-assembly is shown prior to the introduction of the handle hook 11 of the handle 10, not shown in these representations recognizable is only the upper end of the handle hook 11 before insertion into the joint 20 in Figs. 9a and 10a or immediately after insertion into the joint 20 in FIGS. 9b and 10b.

As explained, the essence of the invention is the arrangement of a rocker 40 as a locking element which locks the lever 30 in the preassembly position, wherein the locking element is released from the handle hook 11 in its introduction into the final mounting position of the handle hook 1 and pivoted into the release position. Conversely, accidental release is impossible. The locking element is arranged such that a release of the locking element is possible only by the handle hook 11 in its introduction into the final assembly position.

This means that the bell crank 30 and the hinge 20 are held in the preassembly position and can not be accidentally released from this preassembly position, as long as the handle hook 11 is not placed in its final mounting position in the joint 20. After the complete insertion of the handle hook 11 in the mounting position of the handle hook 11 can be fixed by means of a screw in the joint 20 and thus connected to the lever 30, so that the Handle hook 11 is kinematically coupled to the reversing lever 30 in the assembled state.

Prior to insertion of the handle hook 11 in its final assembly position, the joint 20 and the lever 30 is secured by the steel rocker 40 in the preassembly position to allow the insertion of the handle hook 11 in the joint 20. For this purpose, the hook 43 of the steel rocker 40 engages behind a latching lug 70 arranged on the stationary carrier of the motor vehicle door handle and thereby secures both the joint 20 and the deflection lever 30 kinematically coupled thereto against pivoting back out of the preassembly position according to FIGS. 9a and 10a. This preassembly position according to FIGS. 9 a and 10 a makes it possible to insert the handle hook 11 into the joint 20 for further mounting and fixing by means of the fastening screw 50 within the joint 20.

In the pre-assembly position according to FIG. 9a or FIG. 10a, the steel rocker 40 is pivoted about the pin 23 on the joint 20 in the clockwise direction, whereby the hook 43 of the steel rocker 40 behind the locking lug 70 is engaged and the entire arrangement of the lever 30, Joint 20 and steel rocker 40 secures in the pre-assembly position. The lever is deflected in the preassembly position according to Figures 9a and 10a from its actual Ruehposition out in one of the operating position of the motor vehicle door handle similar or equivalent position and spring-loaded towards the rest position to ensure that after completion of the entire motor vehicle door handle of the Reversing lever 30 coupled handle 10 always returns to the rest position.

Hooks 43 on the steel rocker 40 and locking lugs 70 on the support of the motor vehicle door handle are arranged on both sides, so that a symmetrical design and a uniform securing results in the pre-assembly without the risk of tilting.

The steel rocker 40 has in the illustration of FIG. 9 and 10 in the upper part of a run-on slope 44, on which the handle hook 11 in the introduction into its final assembly position within the joint 20 corresponding to the arrow 80 runs and thereby the steel rocker 40 pivots about the pin 23 around, so that the hook 43 is disengaged behind the locking lug 70, as shown in Figs. 9b and 10b.

The handle hook 11 has a bevel at the front end, so that the sliding on the run-on slope 44, which is formed by the upper part of the rocker 40 in the pre-assembly according to FIGS. 9a and 10a, is simplified. In the illustrated embodiment, the steel rocker 40 rotates by the insertion of the handle hook 11 along the arrow 80 in the final assembly position shown in FIGS. 9b and 10b by 16 ° counterclockwise about the axis formed by the pin 23 axis of rotation of the steel rocker 40. In this case slides lower tab 45 of the steel rocker in a corresponding pocket in the handle hook 11 a. By the rotation of the steel rocker 40 counterclockwise, the hook 43 of the steel rocker 40 is disengaged, so that after the insertion of the handle hook 11 in the final assembly position within the joint 20, the entire assembly from the preassembly position shown in FIGS. 9a and 10a in the Festschraubposition , which corresponds to the rest position of the motor vehicle door handle, can pivot, as shown in Fig. 11. The pivoting in the Festschraubposition takes place automatically due to the spring force on the lever in the direction of the rest position. The overall assembly pivots 50 ° from the pre-assembly position to the fixed-screw position, as shown in FIG. In the Festschraubposition the fastening screw 50 is accessible and can pass through the aligned in the final assembly position holes within the handle hook 11 and the steel rocker 40 and the joint 20 and secure the components against each other. Furthermore, it can be seen in FIG. 11 that, due to the rotation of the components relative to one another, the steel rocker 40 is secured by the cams 38 arranged on the pins 33, 34 on the two arms 31, 32 of the reversing lever, so that the grip hook 11 is no longer can slip out of the final assembly position, but due to the tilting of the components against each other after pivoting in the Festschraubposition shown in FIG. 11 is secured in its final assembly position. 12 shows a plan view from above of the handle hook 11 inserted in the joint 20 before and after the mounting of the fastening screw 50. The fastening screw 50 is screwed in as indicated by the arrow 90 and reaches through the aligned holes in the grip hook 11 and the steel rocker 40 and the joint 20 and secures the components accordingly against each other. The screw head of the fastening screw 50 lies in the handle hook 11 in its bore 12, while the nut 53 is supported on the joint 20. This results in an optimal introduction of force into the component.

The steel rocker 40 within the joint 20 thus serves as a locking element and secures the joint 20 and the lever 30 in the preassembly position to allow the insertion of the handle hook 11 of the handle 10 in the joint 20. The individual components of the motor vehicle door handle are designed so that the steel rocker 40 can be released only by the handle hook 11 of the handle 10 out of the locking position, whereby the assembly of the handle 10 is made possible. After releasing the steel rocker 40 serving as a locking element from the pre-assembly position, the steel rocker 40 is in turn secured by the cam 38 arranged on the reversing lever 30 and the components are tilted against each other, so that slipping out of the handle hook 11 from the joint 20 is not possible. In this position, the fastening screw 50 can then be screwed tight and the handle hooks 11 are finally assembled in the joint 20. Since serving as a locking element steel rocker 40 can be pivoted exclusively by the handle hook 11 on reaching its final assembly position from the locked position into the release position, a simple installation of the motor vehicle door handle is made possible.
