Description

The invention relates to a motor vehicle door handle with a handle which can be shifted from a rest position into an actuating position, a handle hook arranged on the rear of the handle being kinematically coupled to a bell crank in the assembled state, the bell crank being shifted from the rest position into the actuating position acts indirectly or directly on a motor vehicle door lock and the deflection lever is held in a pre-assembly position by means of a locking element, as long as the handle hook is not completely inserted into its assembly position.

Motor vehicle door handles of this type are known. To assemble the handle, it is also known to bring the deflection lever, with which the handle hook arranged on the back of the handle is to be connected during assembly, into a pre-assembly position.

From the DE 101 03 846 A1 Motor vehicle door handle with a bracket that can be fastened in an opening of the door and a handle that can be connected to it is known, the console being assigned a transmission member coupled to the handle in the form of a pivoting lever for transmitting the pivoting movement of an extension of the handle that is remote from the pivoting point of the handle Locking device. It is provided that the transmission member is held in a spring-biased position in a spring-biased position before the handle is installed, this holder being lifted by pivoting the extension into the console is, whereby the transmission member is advanced by the spring and a driving projection associated with the transmission member enters an opening of the extension.

From the DE 199 40 379 C2 Motor vehicle door handle is known with a carrier fastened on the back of the door, with a handle arranged on the front side of the door, which can be transferred from its rest position on the door by a pulling or folding movement into an actuating position with respect to the lock members, the handle with reaches through the door recesses at its two handle ends and at least one handle end of the handle is connected to a lever pivotably mounted on the support and the handle end is connected to the lever by a lever pivoting position close to the door recess, and with one from the front side of the door from the housing which can be plugged into the carrier, the housing being fastened to the carrier in the case of insertion and having a locking cylinder acting on the lock members, a stop which can be reversed automatically between an effective holding position and an ineffective release position between the carrier and the lever eelement is arranged, wherein when the carrier is installed on the door, the holding element for connecting the handle is initially in its holding position, where it holds the lever in its pivoted-out position, and the housing automatically transfers the holding element into its release position when it is inserted into the carrier where the lever is released.

From document EP 1 267 019 A2 is known a door handle for automobiles, with an elongated bearing component made of plastic, which can be attached inside a door, with an elongated handle section, which has at the ends two bearing sections projecting to one side, each through an opening in the outer skin of the door can be received in bearing recesses of the bearing component, the one bearing section being pivotably mounted in the associated bearing recess and the second bearing section being able to reciprocate in the recess, with one pivotably mounted in the bearing component Actuating lever to which an actuating linkage for a lock of the automobile door can be attached and which is biased by a spring in a pivoting direction and has a lever extension which interacts with a contact section of the second bearing section such that the grip section extends from the spring via the lever extension into a starting position is preloaded with a spring section assigned to the second bearing recess, which is deflected in the direction of maximum pretension of the actuating lever when the lever attachment moves, until a free end section of the lever attachment engages behind a stop surface of the spring section and is locked in position and with a ramp surface on the spring section which can be brought into engagement with a deflection surface of the second bearing section when the grip section is moved outward from the bearing component, whereby the stop surface releases the lever shoulder and the lever shoulder comes into contact with the second bearing section.

A disadvantage of the known motor vehicle door handles is that the deflecting lever serving as a transmission member is accidentally released from the pre-assembly position before the final assembly of the handle hook, as a result of which assembly of the handle hook and thus assembly of the entire motor vehicle door handle becomes impossible, with the result that all assemblies are removed again and must be prepared for re-assembly, which means a considerable amount of time and assembly.

The object of the invention is therefore to develop a motor vehicle door handle of the type mentioned at the outset in such a way that this permits easier final assembly of the handle and thus of the entire motor 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 case of the motor vehicle door handle with a handle which can be shifted from a rest position into an actuation position, a handle hook arranged on the rear of the handle being kinematically coupled to a bell crank in the assembled state, the bell crank being shifted from the rest position into the actuation position acts indirectly or directly on a motor vehicle door lock and the deflection lever is held in a pre-assembly position by means of a locking element, as long as the handle hook is not fully inserted into its final assembly position, it is that the locking element is removed from the handle hook when it is inserted into its final assembly position from the locked position into one Release position is shifted.

The essence of the invention is thus the arrangement of a locking element which locks the deflection lever in the preassembly position, the locking element being released from the handle hook when it is introduced into the final assembly position of the handle hook and pivoted into the release position. Conversely, accidental loosening is impossible. The locking element is arranged such that the locking element can only be released by the grip hook when it is introduced into the final assembly position.

This means that the bellcrank is held in the pre-assembly position and cannot be accidentally released from this pre-assembly position as long as the handle hook is not brought into its final assembly position in which it engages in its final assembly position on the bellcrank. After the handle hook has been fully inserted into the assembly position the handle hook can be connected directly or indirectly to the bell crank by means of a screw connection or the like, so that the handle hook is kinematically coupled to the bell crank in the assembled state.

The term final assembly position or final assembly position means that position of the handle hook relative to the deflection lever in which the kinematic coupling between the handle hook and deflection lever can be produced by screwing in a fastening screw and / or by inserting an axis coupling the components or the like, i.e. corresponding to the position which the handle hook and the bellcrank have in relation to one another after completion of the assembly of the motor vehicle door handle.

The term rear of the handle means that side which, when assembled, is seen from the rear by a user of the motor vehicle door handle while the user is showing the front. In the assembled state, the handle hook arranged on the rear engages through an opening in the motor vehicle door, while the handle is arranged such that it can be gripped by a user.

The locking element is particularly preferably a rocker which, in the locking position of the rocker, projects into the installation space for the handle hook and is thus shifted from the locking position into the release position such that the front end of the handle hook runs onto the rocker and the rocker is at Inserting the handle hook in its final assembly position pivoted from the locking position into the release position.

The locking element can thus preferably be a rocker which is shifted from the locking position into the release position by the front end of the handle hook running onto the rocker and the rocker when the handle hook is inserted into its mounting position from the locking position to the release position panned. This rocker can be formed by a part punched out of sheet steel. The two arms of the rocker are preferably not in alignment, but rather the rocker can have an angle between the two arms of the rocker. Such an angling causes the first arm of the rocker, which engages behind an undercut, for example with a hook or the like, to run parallel to the insertion channel of the handle hook in the locking position, while the other arm of the rocker is angled into the installation space and thus into the Inserting channel of the handle hook protrudes, so that this second arm of the rocker is forced to the side by the handle hook when it is inserted into the mounting position of the handle hook, whereby the rocker is pivoted about its axis of rotation and the locking is released.

In the assembled state, the bellcrank serves as a transmission member for transmitting the movement of the handle for opening the motor vehicle door by a user to the motor vehicle door lock, as a result of which the lock is opened in the unlocked state of the lock. The bell crank is directly or indirectly coupled to the motor vehicle door lock.

The rocker serving as a locking element particularly preferably engages behind an undercut and / or a latching lug of a fixed component of the motor vehicle door handle in the pre-assembly position and is displaced into its release position by the handle hook when the handle hook is inserted into its assembly position.

Because the locking element engages behind an undercut of a fixed component of the motor vehicle door handle in the pre-assembly position, the bellcrank is secured and reliably held in the pre-assembly position.

In a preferred embodiment, a joint is pivotally mounted on the deflection lever, in which the grip hook engages in the assembled state, the rocker serving as locking element being arranged on or in the joint so as to be pivotable about an axis of rotation.

The joint, which engages in the assembled state of the handle hook of the handle, allows the movement of the handle to be transmitted to the bell crank acting as a transmission member. The joint serves to couple the handle hook and the bellcrank because the pivot point of the movements of the handle does not have to coincide with the pivot point of the bellcrank. Therefore, an articulated connection between the handle hook and the bell crank must be 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 extending through the grip hook and the deflection lever.

In a particularly preferred embodiment, the rocker serving as a locking element has a run-on slope which, in the locked position of the rocker, projects into the installation space for the handle hook, so that a bevel at the front end of the handle hook runs onto the run-on slope of the rocker and pivots this when the handle hook is inserted .

The locking element in the form of a rocker arranged on the rocker arm or in the form of a rocker arranged on a pivot mounted on the rocker arm is thus shifted into the release position in that the handle hook runs onto the rocker and the front end of the handle hook is an arm of the rocker Presses side, so that the rocker is pivoted about its articulation point on the joint, whereby the locking element pivots from its locking position into its release position and thereby the deflection lever secured in the pre-assembly position is freely movable.

The locking element is thus designed as a rocker arranged on the joint and pivotable about an axis of rotation. As long as the locking element is in engagement and locks the bell crank in the pre-assembly position with the swivel-mounted joint there is an arm of the rocker, which has a run-on slope, in the installation space provided for the handle hook, so that the handle hook when inserted into the assembly position in the Joint runs onto the run-up slope and acts on the rocker by pushing the arm of the rocker forming the run-up slope away by the handle hook and thereby pivoting the rocker about its axis of rotation.

As a result of the pivoting of the rocker about its axis of rotation, the hook, which is arranged on the other arm of the rocker and engages behind an undercut of a fixed component of the motor vehicle door handle, is again released, so that the deflection lever and the joint, which may be pivotably arranged thereon, are released from the pre-assembly position. However, due to the design of the locking element, this release of the deflection lever from the pre-assembly position takes place only after the handle hook has been fully inserted into its final assembly position.

The deflection lever and / or the handle is / are preferably spring-loaded in the direction of the rest position. Such a spring load in the direction of the rest position simultaneously shifts the bell crank and the handle kinematically coupled to the bell crank into the rest position corresponding to the closed position of the motor vehicle door handle, unless a user pulls the handle and the handle into the actuating position corresponding to the open position of the motor vehicle door handle shifted.

The reversing lever is particularly preferably inserted via a push rod and / or a pull rod and / or a cable pull on the motor vehicle door lock, whereby its opening is effected when the motor vehicle door lock is not locked.

The direct or indirect coupling of the bellcrank and the motor vehicle door lock can thus be implemented in a variety of ways, in particular also by a combination of push rods and / or a pull rod and / or a cable pull, which is also referred to as a Bowden cable.

In a particularly preferred embodiment, the deflection lever has at least one latching element which, when an external pulse occurs as a result of a side impact, engages with an accident lock and one Blocked displacement of the bellcrank and the handle from the rest position to its actuation position.

This is a so-called accident lock, which takes effect when a large impulse occurs as a result of an impact and blocks the handle, so that the motor vehicle door is not accidentally opened by the impact impulse due to the inertia of the handle from the rest position to the actuating position is shifted or flung. Accordingly, the movable masses, any spring constants when a spring load is applied and the smoothness of the joints of the overall system and in particular the accident lock are selected so that when a pulse occurs, for example as a result of an accident, the accident lock is so smooth and has a correspondingly lower inertia that first the accident lock comes into engagement with the locking element on the bell crank and blocks both the bell crank and the handle before the handle could be moved out of its rest position as a result of the pulse. This accident prevention system reliably prevents the door from opening due to an impact or other accident.

The locking element is preferably fixed in a form-fitting manner on the deflection lever or on a joint which is pivotably mounted on the deflection lever, in particular in the form of a rocker which engages by means of pins in corresponding receiving bores in the deflection lever or in the joint and can be pivoted about the axis running through the pins.

A joint is preferably rotatably mounted on inwardly projecting pins of two arms of the deflection lever. The handle hook engages in this joint in its final assembly position.

In the assembled state, the handle hook is preferably fixed by means of a screw connection to a joint which is pivotably mounted on the deflection lever. A screw connection has the advantage that this can be solved easily and in particular non-destructively. Alternatively, other connection techniques can also be used.

Fig. 1 shows a perspective view of the handle 10 of a motor vehicle door handle. On the in Fig. 1 the left end 15 of the handle 10, the handle is inserted into a corresponding corresponding receptacle and, when the handle 10 is actuated by a user, can be pivoted out of the rest position about an axis running in the area of the left end 15 of the handle 10.

On the back of the handle 10, the handle hook 11 is arranged, by means of which the handle 10 one in the Fig. 1 reaches through not shown backdrop on the motor vehicle door. The handle hook 11 engages in the joint 20, which is pivotally mounted on the bell crank 30. The handle hook 11 is thus kinematically coupled to the bell crank 30 via the joint 20. In the in Fig. 1 position shown are handle 1 and lever 30 in the actuated position deflected out of the rest position. The lever 30 is shown in the illustration Fig. 1 only a section is shown. The bellcrank itself is in turn articulated on an in Fig. 1 carrier not shown. When the handle 10 is shifted by a user from the rest position into the actuation position, a deflection of the deflection lever 30 into the actuation position thus takes place due to the kinematic coupling of the handle 10 and the deflection lever 30 via the joint 20. The bell crank 30 itself is in turn via a Fig. 1 Cable, not shown, connected to a motor vehicle door lock of the motor vehicle door. If the door lock is not locked, pressing the Handle 10 and the resulting deflection of the bell crank 30 opens the door lock and thus the motor vehicle door.

Since the pivot point of the handle 10 in the area of the Fig. 1 left end 15 and the pivot axis of the bell crank 30 parallel to each other at a distance from each other, the kinematic coupling between the handle 10 via the handle hook 11 and the bell crank 30 by means of the joint 20, which is pivotally mounted on the front end of the bell crank 30. For this purpose, the handle 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 of polypropylene in the illustrated embodiment. The joint 20 and the deflection lever 30 are die-cast parts made of a die-cast zinc alloy. Alternatively, the joint can also be made of plastic.

In Fig. 2 is an enlarged view of the handle hook 11 with the bore 12 is shown. The bore 12 is provided so that, after assembly, a fastening screw can pass through the bore 12 and fix the handle hook 11 in the joint 20.

Fig. 3 shows a perspective view of the steel rocker 40, which serves as a locking element and is inserted into the joint 20. This in Fig. 3b Joint 20 shown in perspective has a circular passage 21 which, in the final assembly position, is aligned with the bore 12 in the handle hook 11, so that the handle hook 11 can be fixed within the joint 20 with a fastening screw penetrating the bores 12 in the handle hook 11 and 21 in the joint 20 is.

In Fig. 3a is a perspective view of the steel rocker 40, which in the joint 20 according to FIG Fig. 3b is shown. The steel rocker is formed in the illustrated embodiment by a high-strength chrome nickel steel. The steel rocker 40 in turn also has a circular passage 41 for the fastening screw, which in the Final assembly position passes through the handle hook 11 through the bore 12 and the joint 20 and the steel rocker 40 arranged in the joint 20 and couples the components together. The steel rocker 40 forms the locking element. The steel rocker 40 has recesses 42, by means of which the steel rocker 40 overlaps corresponding pins within the joint 20, so that the steel rocker 40 can be pivoted about these pins engaging in the recesses 42 within the joint, that is to say that the center point of the pins is the axis of rotation the steel rocker 40 forms. Furthermore, the steel rocker 40 has hooks 43 which, in the preassembly position, engage catches on the support of the motor vehicle door lock and thus secure the joint 20 and the bellcrank in the preassembly position, as will be explained below.

On the sides of the joint 20, of which according to the perspective view Fig. 3b only one is visible, the joint 20 has elongated holes 22, which serve the joint 20 on the two projecting arms 31, 32 of the in Fig. 4 shown deflection lever 30 on the projecting arms 31, 32 inwardly projecting pins 33, 34, so that the joint 20 is pivotable relative to the deflection lever 30.

The bell crank 30 is in Fig. 4 shown in perspective. The two arms 31, 32 can be seen, on the inside of which the pins 33, 34 protrude for receiving the joint 20.

Laterally, the bell crank 30 has two pins 36, 37, which form the axis of rotation of the bell crank 30, about which the bell crank 30 is pivoted when the door handle is actuated.

The bellcrank 30 also has circular bores 35, which serve to couple the bellcrank 30 to a Bowden cable, not shown, via which the bellcrank 30 is coupled to the motor vehicle door lock and, when the motor vehicle door lock is not locked, causes an opening when actuated. The bore 35 serves to receive a Bowden cable.

Via the pins 36, 37, the bellcrank 30 is fixed on a carrier (not shown) of the motor vehicle door lock so as to be pivotable about the axis running through the pins 36, 37. At the front end, the bell crank 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 with the elongated holes 22 is pushed, so that the joint 20 can be pivoted relative to the bell crank 30.

Furthermore, the deflection lever 30 has a latching element 38 which can engage with an accident safety device (not shown in the figures) and can block the deflection lever 30. If a strong external impulse occurs on the motor vehicle door handle, for example as a result of a side impact, the mass of the accident lock compared to the mass of the deflection lever 30 and the handle 10 coupled thereto is selected such that the accident lock is due to the external impulse, as occurs in the event of a side impact on the motor vehicle , is deflected from the rest position and comes into engagement with the latching element 38 on the deflection lever 30, as a result of which both the deflection lever 30 and the handle 10 are blocked against shifting into the actuation position. The latching element 38 thus serves as accident protection in order to avoid that the motor vehicle door could burst open as a result of a side impact.

Fig. 5 shows the preassembly of the joint 20. The fastening screw 50 is inserted into the joint 20, as shown in FIG Fig. 5c is shown. In the Fig. 5a Fixing screw 50 shown in perspective has a first area 51 with a right-hand thread. In the exemplary embodiment shown, section 51 is an M5 right-hand thread. Furthermore, the fastening screw 50 has a further threaded section 52 with a left-hand thread. In the illustrated embodiment, section 52 is an M4 left-hand thread. The fastening screw 50 is as in Fig. 5c shown inserted in the joint 20 and then secured with the lock nut 53. The lock nut 53 is shown in the illustration Exemplary embodiment of a nut with an M4 left-hand thread, which is screwed onto the left-hand thread section 52 of the fastening screw 50 and serves to secure the fastening screw 50 in the joint 20. Furthermore, the lock nut 53 forms a stop shoulder after assembly is complete. The lock nut 53 is itself secured by screwing it onto the left-hand thread section 52 of the fastening screw 50 by deforming the thread.

In the perspective view according to the Figures 5c and 5d can be seen bearing pin 23 inside the joint 20. The steel rocker 40 with its corresponding recesses 42 is pushed onto this bearing pin 23, so that the steel rocker 40 can be pivoted around the bearing pin 23 within the joint 20. The bearing pins 23 thus form the axis of rotation of the steel rocker 40.

The insertion of the steel rocker 40 in the joint 20 is in Fig. 6a shown. For this purpose, the steel rocker 40 is pushed upwards into the joint 20 from below as shown by the arrow 60 and then moved forward so that the recesses 42 of the steel rocker 40 overlap the pins 23 arranged within the joint 20, so that the rocker 40 within of the joint 20 is pivotally mounted around the pin 23. Fig. 6b shows a perspective view of the joint 20 with the steel rocker 40 inserted therein and the preassembled fastening screw 50.

The insertion of the joint 20 with the steel rocker 40 pre-assembled therein into the bell crank 30 is shown in FIG Figures 7 and 8th . For this purpose, the reversed joint 20 is as shown by the dashed arrows in Fig. 7 shown from below with its laterally arranged long elongated holes 22 pushed over the pins 33, 34 on the two projecting arms 31, 32 of the bell crank 30 and then as in Fig. 7b shown pivoted through 180 ° into its actual orientation relative to the bell crank 30. Fig. 8 shows the preassembled joint 20 on the bell crank 30 in a perspective view.

Fig. 9 shows side views of the bell crank 30 and the joint 20 with the steel rocker 40, which serves as a locking element, in the pre-assembly position in Fig. 9a before inserting the handle hook 11 and in Fig. 9b after inserting the handle hook 11 in its final assembly position in the joint 20. In Fig. 10 are sectional views according to the line AA of the bell crank 30 and the joint 20 with the steel rocker 40 pivotally mounted in the joint 20 in the pre-assembly position according to Fig. 10a before inserting the handle hook 11 and in Fig. 10b after the introduction of the handle hook 11 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 is explained.

In the Fig. 9a and 10a the pre-assembly position is shown in each case before the insertion of the handle hook 11 of the handle 10, which is not shown in these illustrations. Only the upper end of the handle hook 11 can be seen before the insertion into the joint 20 in FIG Fig. 9a and 10a or immediately after insertion into the joint 20 in the Fig. 9b and 10b .

As explained, the essence of the invention is the arrangement of a rocker 40 as a locking element, which locks the bell crank 30 in the preassembly position, the locking element being released from the handle hook 11 when it is introduced into the final mounting position of the handle hook 11 and pivoted into the release position. Conversely, accidental loosening is impossible. The locking element is arranged such that the locking element can only be released by the handle hook 11 when it is introduced into the final assembly position.

This means that the bellcrank 30 and the joint 20 are held in the preassembly position and cannot be inadvertently released from this preassembly position as long as the handle hook 11 is not inserted into its final installation position in the joint 20. After the handle hook 11 has been fully inserted into the assembly position, the handle hook 11 can be fixed in the joint 20 by means of a screw connection and can thus be connected to the bell crank 30, so that the Handle hook 11 is kinematically coupled to the lever 30 in the assembled state.

Before the handle hook 11 is pushed into its final assembly position, the joint 20 and the deflection lever 30 are secured in the pre-assembly position by the steel rocker 40 in order to enable the handle hook 11 to be pushed into the joint 20. For this purpose, the hook 43 of the steel rocker 40 engages behind a locking lug 70 arranged on the fixed support of the motor vehicle door handle and thereby secures both the joint 20 and the linkage lever 30 kinematically coupled therewith against pivoting back from the preassembly position according to FIGS Figures 9a and 10a . This pre-assembly position according to the Fig. 9a and 10a enables the insertion of the handle hook 11 into the joint 20 for further assembly and fixing by means of the fastening screw 50 within the joint 20.

In the pre-assembly position according to Fig. 9a respectively Fig. 10a the steel rocker 40 is pivoted clockwise around the pin 23 on the joint 20, as a result of which the hook 43 of the steel rocker 40 engages behind the latch 70 and secures the entire arrangement of the deflection lever 30, joint 20 and steel rocker 40 in the preassembly position. The bell crank is in the pre-assembly position according to Figures 9a and 10a deflected from its actual rest position into a position similar or corresponding to the actuation position of the motor vehicle door handle and spring-loaded in the direction of the rest position, in order to ensure that after assembly of the entire motor vehicle door handle has been completed, the handle 10 coupled to the bell crank 30 always returns to the rest position.

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

The steel rocker 40 points in the illustration according to Fig. 9 and 10th in the upper part of a run-on slope 44, on which the handle hook 11 when inserted in its final assembly position within the joint 20 runs according to the arrow 80, thereby pivoting the steel rocker 40 around the pin 23, so that the hook 43 disengages behind the latch 70, as shown in FIGS Fig. 9b and 10b is shown.

The handle hook 11 has a bevel at the front end, so that the sliding onto the run-on bevel 44, which is caused by the upper part of the rocker 40 in the pre-assembly position according to FIGS Fig. 9a and 10a is formed, is simplified. In the exemplary embodiment shown, the steel rocker 40 rotates by pushing in the handle hook 11 along the arrow 80 in its final assembly position according to FIGS Fig. 9b and 10b by 16 ° counterclockwise around the axis of rotation of the steel rocker 40 formed by the pins 23. The lower tab 45 of the steel rocker slides into a corresponding pocket in the handle hook 11. By rotating the steel rocker 40 counterclockwise, the hook 43 of the steel rocker 40 is disengaged, so that after inserting the handle hook 11 in its final assembly position within the joint 20, the overall arrangement from the pre-assembly position according to FIGS Fig. 9a and 10a can pivot into the screwed position, which corresponds to the rest position of the motor vehicle door handle, as in Fig. 11 is shown. The pivoting into the screwed position takes place automatically due to the spring force on the bell crank in the direction of the rest position. The overall arrangement swivels by 50 ° from the pre-assembly position to the screw-in position, as shown in Fig. 11 is shown. In the screw-in position, the fastening screw 50 is accessible and can reach through the bores aligned in the final assembly position within the handle hook 11 as well as the steel rocker 40 and the joint 20 and secure the components against one another. Furthermore, in Fig. 11 Recognizable that due to the rotation of the components relative to each other, the steel rocker 40 is secured by the cams 38 arranged on the pins 33, 34 on the two arms 31, 32 of the deflection lever, so that the grip hook 11 can no longer slide out of the final assembly position, but instead due to the canting of the components against each other after pivoting into the screwed position Fig. 11 is secured in its final assembly position.

Fig. 12 shows a top view of the handle hook 11 used in the joint 20 before and after the mounting of the fastening screw 50. The fastening screw 50 is, as indicated by the arrow 90, screwed in and engages through the aligned holes in the handle hook 11 and the steel rocker 40 and the Joint 20 and accordingly secures the components 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 bellcrank 30 in the preassembly position in order to enable the handle hook 11 of the handle 10 to be inserted into the joint 20. The individual components of the motor vehicle door handle are designed in such a way that the steel rocker 40 can only be released from the locking position by the handle hook 11 of the handle 10, as a result of which the handle 10 can be installed. After the steel rocker 40 serving as a locking element has been released from the pre-assembly position, the steel rocker 40 is in turn secured by the cams 38 arranged on the deflection lever 30 and the components are tilted against each other in such a way that the handle hook 11 cannot slide out of the joint 20. In this position, the fastening screw 50 can then be screwed tight and the handle hook 11 can be finally assembled in the joint 20. Since the steel rocker 40 serving as the locking element can only be pivoted from the locking position into the release position by the handle hook 11 when it reaches its final assembly position, simple mounting of the motor vehicle door handle is made possible.
