Description

The invention relates to a door handle arrangement for a motor vehicle, having a handle support, a handle and a base plate which is movably mounted on the handle support and which can be moved relative to the handle support and on which the handle is mounted movably relative to the base plate, the The handle can assume at least one rest position and one handling position in which the handle, when installed in a vehicle door for actuation, is arranged set out in a raising direction relative to an outside of the vehicle door, and wherein the base plate on the handle support moves from a rest position in which the handle is in is arranged in its rest position, is designed to be movable into a working position, in which the handle is arranged in its handling position, and wherein a mass balancing element is mounted on the base plate, which is movably mounted on the handle support, which movement of the handle out of its rest position is at a it is designed to block the inertial force acting on the handle in the event of a vehicle accident.

A door handle assembly of the type described above is for example from U.S. 2017/292297 A1 known.

Door handle assemblies for a motor vehicle can be designed as an inside or outside handle, with the present invention relating to a door handle assembly for an outside handle. There are a large number of different designs and embodiments for such door handle arrangements, in which, for example, the handle support is fastened to the rear of the vehicle door, ie on the inside of the motor vehicle. In such embodiments, the handle attached to the handle support usually protrudes from the vehicle door and spoils the aesthetic impression of the motor vehicle the vehicle aerodynamics. In order to avoid these disadvantages, door handle arrangements are known from the prior art in which the outside of the handle in its rest position, in which it is not used, runs almost flush with the outer contour of the vehicle door, ie flush with the street. To open the vehicle door, such a handle can be transferred into a handling position in which the handle protrudes relative to the outer contour of the vehicle door and can be gripped from behind and pivoted by a user in order to open the vehicle door.

Such a door handle assembly is, for example, for electric cars from Tesla Motors Inc. and from DE 10 2013 212 198 A1 known. This known door handle arrangement has a handle which is arranged flush with the street in its rest position and which can be moved, driven by a motor, from the rest position into a handling position. Such a handle is preferably used in electric cars, in which the handle extends exclusively with a power-driven drive from its flush or flush rest position, in which the handle is arranged to reduce air resistance, into the handling position when an authorized operator approaches the motor vehicle . As soon as the handle is no longer needed, it moves back into the rest position and thus disappears into the body to avoid generating air resistance.

Furthermore, the applicant is aware of constructions of door handle arrangements of the type described above, in which the handle is movably mounted on a base plate, the base plate in turn being movably mounted on a handle carrier in a deployment direction of the handle. To open a vehicle door, the base plate is moved in the opening direction, as a result of which the handle reaches an extended position in relation to the vehicle door. In this extended position, a user can then reach behind the handle to to open the vehicle door. For these constructions known to the applicant, the measures to secure the base plate and the handle in the event of a vehicle accident are very complex and require a lot of space to prevent the base plate from extending out or the handle from swiveling out in the event of a vehicle accident as a result of inertial forces acting on the handle to avoid, with functional sequences for normal operation and emergency operation of the door handle assembly must be considered, which increases the complexity of the design.

The object of the invention is to provide a solution that provides an improved door handle arrangement for a motor vehicle in a structurally simple manner and in particular an innovative concept for preventing the vehicle door from being opened unintentionally in the event of a vehicle accident.

In a door handle arrangement of the type described above, the object is achieved according to the invention in that the mass balancing element is designed as a one-armed lever which is rotatably mounted on the base plate.

Advantageous and expedient refinements and developments of the invention result from the dependent claims.

The invention provides a door handle arrangement for a motor vehicle that is characterized by a simple construction and a special concept for securing the door handle arrangement against an undesired opening of a vehicle door in the event of a vehicle accident when inertial forces act on the door handle arrangement. The fuse according to the invention allows the handle to be mounted on a base plate, which is moved from a rest position to an operative position for actuation of the handle, the handle being moved with the base plate and being pivotably mounted on it. Just like the handle, the mass balancing element also moves with the base plate.

In one embodiment, the invention provides that the handle is arranged on the base plate in a non-pivoted position in the rest position and in the handling position, with the handle being designed to be movable manually by a user from the handling position into an operating position for opening the vehicle door, and with the handle in the handling position is pivoted relative to the base plate.

Furthermore, in an embodiment of the invention it is provided that the mass balancing element is rotatably mounted about a hinge axis arranged on the base plate. The articulated axis is the articulated connection between a bearing lever and the base plate, so that an existing axis is used for the mass balancing element at the same time.

Accordingly, in a further embodiment, the invention provides that the base plate is connected to the handle carrier via a bearing lever and the handle is pivotably mounted via an actuating axis arranged on the base plate, with the bearing lever being pivoted about an extension axis arranged on the handle carrier. The storage lever is used to extend the base plate.

It is particularly favorable for compensating for all moments acting in the event of a vehicle accident if the joint axis is arranged between the actuating axis and the extension axis.

In an embodiment of the door handle arrangement, the invention also provides that the mass balancing element has a mass body arranged at a distance from the joint axis and an elastically deformable alignment element pushes the mass balancing element in the direction of the handle.

A simple and effective measure is given in an embodiment of the invention in that the elastically deformable alignment element is designed as a torsion spring, which is wound around the hinge axis and from which a first spring leg is supported on the base plate and a second spring leg on the mass balancing element.

So that the mass balancing element can lose its maximum effectiveness and is held in a necessary position, the invention provides in an embodiment that the base plate has a stop surface, with the elastically deformable alignment element pressing the mass body at least in sections against the stop surface, which is located between the handle and the mass body is arranged.

It is structurally particularly favorable and the installation space is utilized when, in an embodiment of the invention, the mass body is mounted pivotably about the joint axis only in a direction pointing away from the handle.

For a targeted action on the handle in the event of a vehicle accident, it is advantageous in an embodiment of the invention if a contact surface is formed on the mass body, which is formed aligned with a contact point formed on the handle.

Finally, in an embodiment of the invention, it is provided that the contact surface is designed to rise in a ramp-like manner in a direction pointing away from the joint axis. As a result, the effect of the compensation by the mass balancing element can be increased.

According to the invention, the handle when installed in a vehicle door in the rest position can be arranged running flush with the outside of the vehicle door or opposite the outside of the vehicle door in an opening direction in a non-operable position for an operator. Both positions have aerodynamic advantages compared to a handle that is permanently arranged in the handling position.

It is understood that the features mentioned above and to be explained below not only in the each specified combination, but can also be used in other combinations or on their own, without departing from the scope of the present invention. The scope of the invention is defined only by the claims.

In figure 1 a motor vehicle 1 in the form of a car is shown as an example, which in the example has four vehicle doors 2 (two of which are figure 1 apparent) has, which can be opened via a respective door handle assembly 3 and in particular with the help of a handle 4 of the door handle assembly 3. The vehicle doors 2 are firmly closed via a respective door lock 5 and can only be opened from the outside via a respective movement of the handle 4 . During normal operation of the door handle arrangement 3, this movement on the handle 4 consists of a pulling movement, which is detected, for example, by a micro-button, whereupon the lock 5 of the vehicle door 2 is opened electrically. The associated vehicle door 2 can then be opened by the corresponding movement of the handle 4 . In the event of a currentless emergency operation, the door handle arrangement 3 is designed in such a way that the vehicle door 2 can also be opened manually by actuating the handle 4 by an operator. In emergency operation, the corresponding movement of the handle 4 is transmitted to the corresponding lock 5 via a vehicle door opening means 6, which in the present case is a Bowden cable system. For the purposes of the invention, normal operation is to be understood as an operating mode of the door handle arrangement in which vehicle doors (and flaps) are locked and unlocked purely electrically by means of a drive unit, with the handle 4 also being moved electrically from a rest position into a handling position in which a user can operate the handle 4 to open the vehicle door 2 is moved. Furthermore, within the meaning of the invention, de-energized emergency operation is to be understood as an operating mode in which the vehicle electronics have failed (e.g. if the vehicle battery is empty) and the handle 4 must be manually moved mechanically by a user into the handling position so that a user can Handle 4 for unlocking and opening the vehicle door 2 can operate.

the figure 2 shows a perspective view of one of the vehicle doors 2 and the handle 4 used to open the vehicle door 2. In FIG figure 2 is the handle 4 - when installing the Door handle arrangement 3 in the vehicle door 2 - arranged approximately flush with the outside 7 of the vehicle door 2, ie flush with the road or flush with the surface. In this position, the handle 4 is in a rest position in which it is not used. It should be pointed out that the present invention is not limited to handles 4 which are arranged flush or flush with the surface in their rest position. Rather, the invention also includes embodiments in which the handle 4 is arranged in relation to the outside 7 of the vehicle door 2 such that the handle 4 can not be actuated or handled by an operator because the handle 4 in this position by a Operator cannot be reached from behind. from the inside figure 2 In the rest position shown, the handle 4 is in a figure 3 shown handling position can be converted, in which it protrudes from the outside 7 of the vehicle door 2. Accordingly, the handle 4 is arranged protruding from the vehicle door 2 in its handling position. In this handling position that protrudes or is extended from the outside 7 , an operator can reach behind the handle 4 and actuate or handle it in order to open the vehicle door 2 . According to the present invention, the handle 4 is transferred from the rest position to the handling position by means of a mechanical actuating element 8 which, in normal operation, is actuated by a drive motor 9 (see, for example, Figures 6 and 7 ) is moved. Proximity sensors or other sensors can be provided for normal operation in order to start up the drive motor 9 accordingly and thereby move the actuating element 8 so that the handle 4 is brought from the rest position into the handling position as soon as an operator approaches the door handle arrangement 3 or the handle 4 approaches. For this purpose, proximity sensors known from the prior art can be installed in the handle 4, which send a signal to a vehicle control device when an authorized operator or ID transmitter is detected send, whereby the drive motor 9 is put into operation and ensures the issue of the handle 4 in the handling position.

The door handle arrangement 3 according to the invention comprises the handle 4 and a handle support 10 which can be attached to the vehicle door 2 on the inside. The handle support 10 supports or supports the remaining components of the door handle arrangement 3, with other components being able to be attached to the handle support 10 as well. The drive motor 9 can be attached to the handle support 10 or to the vehicle door 2 or in the area of the vehicle door 2 . In the Figures 2 and 3 the handle support 10 can be seen behind the outside 7 of the vehicle door 2 . How from the Figures 4 and 5 can be seen, a base plate 11 is mounted on the handle support 10, which is movable relative to the handle support 10 and on which the handle 4 is mounted. the Figures 4 and 5 show quasi-transparent views of the door handle assembly 3, wherein in figure 4 the base plate 11 is in a rest position and at the same time the handle 4 mounted on the base plate 11 is in its rest position, whereas in figure 5 the base plate 11 is in a working position and at the same time the handle 4 mounted on the base plate 11 is in its handling position. As the comparison of the different positions of base plate 11 and handle 4 in the Figures 4 and 5 shows, the handle 4 is arranged immovably on the base plate 11 when the base plate 11 moves from the rest position into the working position. Consequently, when the base plate 11 is moved from the rest position into the handling position, the handle 4 is moved along with the base plate 11 without the handle 4 moving relative to the base plate 11 . Accordingly, the base plate 11 is designed to move the handle 4 from the rest position into the handling position. The movement of the base plate 11 and the handle 4 takes place in a direction transverse to the handle support 10 Directed deployment direction 12, for example from the Figures 4 and 5 is evident.

In the figure 5 is the base plate 11 out of its in figure 4 shown rest position moved in its working position, so that the handle 4 is arranged moved from its rest position in its handling position. These situations are again in the Figures 10 and 11 shown, wherein only the handle 4, a bearing lever 14, a movement lever 15 are shown as components of the door handle assembly 3 here. The bearing lever 14 and the movement lever 15 are used to extend the base plate 11, with the bearing lever 14 being rotatably mounted about an extension axis 16 arranged on the handle carrier 10, whereas the movement lever 15 is rotatably mounted about a pivot axis 17 arranged on the handle carrier 10. In normal operation, for example, from the Figures 6 and 7 Visible drive motor 9 in operation and moves the actuating element 8, which in turn acts on the bearing lever 14 and rotates it about the extension axis 14, whereby the base plate 11 from the in figure 10 rest position shown in figure 11 working position shown. The base plate 11 is consequently connected in an articulated manner to the handle support 10 via the bearing lever 14 and also the movement lever 15, with only the bearing lever 14 being driven in order to move the base plate 11. The movement of the bearing lever 14 via the base plate 11 and a transmission bracket 18 extending parallel to the base plate 11 (see, for example, figure 7 ) transferred to the movement lever 15. The base plate 11 on the handle support 10 is thus designed to be movable from the rest position, in which the handle 4 is arranged in its rest position, into the working position, in which the handle 4 is arranged in its handling position, with the handle 4 in the handling position at Installed in a vehicle door 2 for actuation relative to the outside 7 of the vehicle door 2 in the deployment direction 12 arranged is how it figure 11 indicates. In the rest position of the base plate 11, which is movably mounted relative to the handle support 10, the mounting lever 14 is arranged in a retracted position (see FIG figure 10 ), whereas in the working position of the base plate 11 the bearing lever 14 is arranged in an extended position (see figure 11 ). In figure 12 is the handle 4 from the in figure 11 shown handling position now pivoted into an operating position, which is done by an actuation by a user who pulls on the handle 4. In the figure 11 The operating position of the handle 4 shown is only intended to demonstrate the pivotability of the handle 4 on the base plate 11 as an example. In normal operation, pivoting the handle 4 by 2° is sufficient to actuate a microswitch for electrically opening the vehicle door 2, whereas in emergency operation a greater stroke or pivoting of the handle 4 by a larger angle causes the Bowden cable system 6 is used to mechanically open the vehicle door 2. The handle 4 is pivotally mounted on a base plate 11 arranged on the actuating axis 19, as is the case, for example figure 12 indicates. From the Figures 10 to 12 As a result, the handle 4 is arranged non-pivoted on the base plate 11 in the rest position and in the handling position, with the handle 4 being designed to be movable manually by a user from the handling position into the actuated position for opening the vehicle door 2, with the handle 4 is pivoted relative to the base plate 11 in the operating position. The handle 4 is made up of several parts, which for example figure 8 can be seen, and comprises a visor body 20 and a of the visor body 4 in the assembled state at least partially covered main body 21, wherein in the representation of figure 12 the visor body 20 is shown transparent so that the extension axis 16 can be seen.

After the basic functioning of the door handle arrangement 3 for a deployment process and an actuation of the handle 4 has been described in very general terms, the special features of the invention that are responsible for blocking or blocking the extension movement will now be discussed, so that in the event of a vehicle accident as a result of the inertial forces acting on the door handle arrangement 3, the base plate 11 does not undesirably extend into its extended position and the handle 4 is undesirably pivoted into an operating position. A distinction is made below both between normal operation and emergency operation of the door handle arrangement 3 and between blocking or blocking of the base plate 11 and the handle 4 .

the Figures 24 to 29 are aimed at blocking the base plate 11 in its rest position and unblocking to operate the handle 4 can, with the Figures 25 and 26 to a normal operation of the door handle assembly 3 and the Figures 27 to 29 refer to an emergency operation of the door handle assembly 3.

In figure 24 When the door handle assembly 3 is not in use, the base plate 11 is secured to the handle bracket 10 so that the base plate 11 remains in its rest position in the event of a vehicle crash. In the rest position of the base plate 11, a bearing lever lock 22 engages with the bearing lever 14 and blocks movement of the bearing lever 14 out of the retracted position. The storage lever lock 22 is, for example in the Figures 17 and 18 shown in more detail and designed in the form of a one-armed lever, wherein the storage lever lock 22 is rotatably mounted on the handle support 10 about a locking axis 23. The storage lever lock 22 is about the locking axis 23 in a locked position in which the storage lever lock 22 is in engagement with the storage lever 14, and in a release position in which the storage lever lock 22 with the storage lever 14 except Is engaged and the storage lever 14 releases, rotatably mounted on the handle support 10. The storage lever lock 22 is located in figure 24 in the locked position, with the Figures 17 and 18 show this situation for the storage lever 14 and the storage lever lock 22. To block or block a movement of the base plate 11 out of the rest position, a locking hook 24 is formed on the bearing lever lock 22, which in the locked position engages behind a locking projection 25 formed on the bearing lever 14 in such a way that the bearing lever lock 22 blocks the bearing lever 14 holds in the retracted position. This engaged position is in the Figures 17 and 18 shown where figure 18 is a sectional view. The bearing lever lock 22 is spring-loaded in the direction of the bearing lever 14 so that it can be seen that the spring force is to be dimensioned in such a way that it withstands an inertial force acting in the event of a vehicle accident.

To cancel this blocking or blocking of the bearing lever 14 in normal operation of the door handle arrangement 3, the drive motor 9 is put into operation when an authorized user approaches, which in turn moves the actuating element 8. The drive motor 9 rotates the adjusting element 8 clockwise about a drive axle 26 mounted on the handle support 10, so that the motor-driven adjusting element 8 moves from an in figure 24 shown zero position out into an in figure 25 Normal operating position shown moves or rotates. The rotation of the actuating element 8 from the zero position into the normal operating position brings about two aspects that take place one after the other. By rotating the actuating element 8 from the zero position, the actuating element 8 first moves the storage lever lock 22 from the locked position to the release position, which is from figure 25 is evident. To move the storage lever lock 22 from the locked position to the release position, on the actuating element 8 is a Movement circumference contour 28 formed from the Figures 13 and 14 is evident. The motion perimeter contour 28 has a neutral perimeter portion 29 and an unlock perimeter portion 30 . At this time, the unlocking peripheral portion 30 is provided with a larger clearance 31 (see, for example figure 14 ) to the drive axle 26 is formed as the neutral peripheral portion 29 . This larger distance 31 results from the fact that the neutral perimeter portion 29 is formed as an indentation or cut in the perimeter wall of the perimeter contour 28 in the illustrated embodiment, whereas the unlocking perimeter portion 30 corresponds to the perimeter wall of the perimeter contour 28, which is circular runs on a constant radius. In the locking position, a shoulder 32 protruding from the bearing lever lock 22 in the direction of the actuating element 8 is arranged with its free end in the neutral peripheral section 29 designed as a notch. If the actuating element 8 is now rotated about the drive axis 26 by the drive motor 9, the neutral peripheral section 29 moves away from the lug 32 of the support lever lock 22 and the lug 32 rests against the unlocking peripheral section 30, whereby due to the If the radius of the unlocking peripheral section 30 is larger, the storage lever lock 22 is pivoted about the locking axis 23 in a direction pointing away from the actuating element 8 , as a result of which the locking hook 24 disengages from the locking projection 25 . In other words, when the actuating element 8 is in the zero position, the bearing lever lock 22 rests against the neutral circumferential section 29 and is arranged in the locked position, whereas in the normal operating position of the actuating element 8 the bearing lever lock 22 moves from the unlocking circumferential section 30 to the release position is crowded. Accordingly, the actuating element 8 is designed to move the bearing lever lock 22 from the locked position into the release position, in that the actuating element 8 urges the spring-loaded bearing lever catch 22 in a direction away from the bearing lever 14 as it moves from the neutral position to the normal operating position. The storage lever lock 22 thus releases the storage lever 14, which does not automatically move into the extended position, since a lever return spring 27 (see, for example, figures 7 , 21 and 30 ) exerts a force acting in the direction of the retracted position on the bearing lever 14 . In a step following the release of the bearing lever 14, the actuating element 8 ensures that, after the bearing lever 14 has been released, the bearing lever lock 22 is moved into the release position, so that the bearing lever 14 is moved into the extended position, so that after the two steps, all the components mentioned are in figure 25 assume the positions shown. So that the bearing lever 14 is moved into its extended position and the base plate 11 is moved into the working position and the handle 4 into its opened handling position, a driver contour 33 is formed on the actuating element 8 (see Fig Figures 13 or 15 ). This driver contour 33, which is designed as a web extending in the axial direction, comes into contact with the bearing lever 14 and forces it into the extended position when the actuating element 8 rotates. The bearing lever 14 is further formed with a first lever arm 34 and a second lever arm 35, the first lever arm 34 being articulated to the base plate 11 via an articulation axis 36, such as that shown in FIG Figures 10 to 12 demonstrate. Thus, when the actuating element 8 moves from the zero position into the normal operating position, the driver contour 33 presses against the second lever arm 35 and moves the bearing lever 14 from the retracted position into the extended position. How from the figure 16 As can be seen, the driver contour 33 is formed on the actuating element 8 in relation to the drive axis 26 axially and circumferentially offset relative to the contour of the circumference of movement 28 . So that the actuator 8 first When the bearing lever lock 22 is moved out of the locked position and then the bearing lever 14 is moved into the extended position, the driver contour 33 is offset circumferentially with respect to the contour of the circumference of movement 28 on the actuating element 8, so that the contour of the circumference of movement 28 first acts on the bearing lever lock 22 and then, after the movement of the storage lever lock 22 from the locked position into the release position, the driver contour 33 moves the storage lever 14 into the extended position. In order to keep the duration of these two steps short and to set the handle 4 out quickly, the driver contour 33 is designed with a greater radial distance 37 from the drive axis 26 than the movement circumference contour 28, as shown in FIG figure 16 is evident. from the inside figure 25 In the position shown, the handle 4 can now be gripped behind by a user in normal operation of the door handle arrangement 3 and pivoted to open the vehicle door 2, with a pivoting of about 2° about the actuating axis 19 being sufficient in normal operation to switch a microbutton to the electric door opening activate. How from the figure 26 As can be seen, the bearing lever lock 22 remains in place even when the handle 4 moves into the in figure 26 shown operating position in the release position. The storage lever lock 22 only returns to the locked position when the actuating element 8 is moved back into its zero position, in which the storage lever lock 22 is then in engagement with the storage lever 14, with the two steps for unlocking and opening described above also going through here but in reverse order.

the Figures 27 to 29 show a de-energized emergency operation of the door handle assembly 3 when the vehicle electronics are not working, for example due to a dead vehicle battery and the actuating element 8 for electrically opening a vehicle door 2 cannot be put into operation. To the in figure 24 To clear the blocking or blocking of the base plate 11 shown, the door handle arrangement 3 is designed in such a way that a user can move the handle 4 inwards against the deployment direction 12 in an emergency. Such a position is in figure 27 shown, in which the handle 4 is arranged in an emergency operation of the door handle arrangement 3 moved inwards against the raising direction 12 . The inward movement of the handle 4 is possible because the actuating axis 19, about which the handle 4 is pivotably mounted on the base plate 11, is mounted on the base plate 11 so that it can move counter to the deployment direction 12 against a restoring force exerted by a restoring element 38 (see Fig figure 9 ). The base plate 11 has two support arms which extend in the direction of the raising direction 12, the two support arms 39 being inserted into corresponding receptacles in the handle 4 and being connected there to the handle 4 in an articulated manner. The restoring element 38 is designed to be elastically deformable and is designed in the manner of a torsion spring in the exemplary embodiment, with the restoring element 38 being accommodated in a receiving space 40 of one of the two bearing arms 39 and pressing against the actuating axis 19 in the deployment direction 12 . So that the movement of the actuating axis 19 is guided counter to the opening direction 12, a guide recess 41 is formed in the bearing arm 39, in which the actuating axis 19 can be moved to a limited extent. Due to this inward movement of the handle 4 or a movement of the actuating axis 19, the deployment direction 12 escapes, which in figure 27 is shown, an actuating projection 42 formed on the handle 4 (see, for example, figures 8 and 20 ) in contact with a locking lever 43 (see figure 27 ) and pivots the blocking lever 43 about a lever axis 44, via which the blocking lever 43 is rotatably mounted on the handle support 10. The blocking lever 43 is between a Blocking position and a neutral position movable. In figure 24 , in which the base plate 11 is blocked or kept blocked from an extension movement on the handle carrier 10, the blocking lever 43 is arranged in its blocking position, whereas the inward movement of the handle 4 causes the actuating projection 42 to move the blocking lever 43 from its blocking position to its neutral position , This movement being a pivoting movement about the lever axis 44, by which the blocking lever 43 is moved in a direction away from the handle 4. The blocking lever 43 is spring-loaded on the handle support 10 so that a force acting in the direction of the blocking position acts on the blocking lever 43 and this force strives to hold the blocking lever 43 in its blocking position or to push it back into its blocking position. Movement of the blocking lever 43 from a blocking position to its neutral position also moves the support lever lock 22 from its locked position to its unlocked position. Like for example from the figure 23 As can be seen, the free end of the bearing lever lock 22 rests on a side of the blocking lever 43 facing away from the handle 4, so that a movement of the blocking lever 43 in a direction pointing away from the handle 4 moves the bearing lever lock 22 in a direction away from the handle 4 pioneering direction as it moves in figure 27 is shown. Thus, when the blocking lever 43 moves from its blocking position into its neutral position, the blocking lever 43 pushes the bearing lever lock 22 , which is spring-loaded in the direction of its blocking position, into the release position pointing away from the bearing lever 14 . As a result, the movement of the storage lever 14 is released, since the storage lever lock 22 is now arranged in its release position. However, since the bearing lever 14 is held in its retracted position by the lever return spring 27, an emergency extension element 45 is provided for extending the base plate 11 in emergency operation of the door handle arrangement 3 . The emergency extension element 45 is on the handle support 10 between a basic position (see figure 24 ) and an emergency operating position (see figure 27 ) rotatably mounted, in the illustrated embodiment, the Notausfahrelement 45 is mounted on the extension axis 16, on which the bearing lever 14 is also mounted. The emergency extension element 45 is designed to move the bearing lever 14 into the extended position during its movement into the emergency operating position. The emergency extension element 45 is formed with a control lever arm 46, a free end of which bears against the blocking lever 43 when the base plate 11 is in the rest position and is held blocked by the blocking lever 43 in the basic position. In other words, the blocking lever 43 rests against the control lever arm 46 in the basic position and blocks a movement of the emergency extension element 45 in the direction of the emergency operating position. Due to the movement of the blocking lever 43 from its blocking position to its neutral position caused by the handle 4, the blocking lever 43 spring-loaded in the direction of the handle 4 releases the emergency extension element 45 for movement from the basic position into the emergency operating position. How from the Figures 24 to 26 As can be seen, the blocking lever 43 is arranged in its blocking position during normal operation of the door handle arrangement 3, with the blocking lever 43 holding the emergency extension element 45 in the basic position. In figure 27 is now the Notausfahrelement 45 for the de-energized emergency operation for a movement towards its Notbetriebsstellung free, the Notausfahrelement 45 is spring-loaded towards its Notbetriebsstellung. For this purpose, an extension spring 47, which is designed as a torsion spring, is wound around the extension axis 16, the spring legs being supported both on the handle support 10 and on the emergency extension element 45. Such as from figure 21 can be seen is a driver element 48 is formed on the control lever arm 46 of the emergency extension element 45 . When the emergency extension element 45 moves from the basic position to the emergency operating position, the driver element 48 comes into contact with the bearing lever 14 and forces the bearing lever 14 into the extended position, as shown in FIG figure 28 is shown, in which the storage lever 14 is now arranged in its extended position. It can be seen that the force of the extension spring 47 is larger than the force of the lever return spring 27. A stopper lever 49 is formed on the emergency extension element 45 so that the base plate 11 is not moved beyond the extended position. When the emergency extension element 45 moves, the stopper lever 49 moves from the basic position into the emergency operating position in the direction of the actuating element 8. In the emergency operating position, the stopper lever 49 then rests against a stopper contour 50 formed on the actuating element 8, as shown in the Figures 22 and 28 is shown. In the manner described above, the handle 4 is manually deployed by a user via the base plate 11 in a de-energized emergency operation, so that the handle 4 can now be actuated and pivoted in the emergency operation, as is shown in figure 29 is shown. When the handle 4 is pivoted by a user, the vehicle door opening means 6 designed in the manner of a Bowden cable is actuated via a Bowden cable lever 51 in order to open a vehicle door 2 in emergency operation.

the Figures 30 to 33 are aimed at compensating for an inertial force acting on the handle 4 in the event of a vehicle accident, for example, in order to prevent the handle 4 from swiveling out unintentionally. For this purpose, a mass balancing element 52 is mounted on the base plate 11 movably mounted on the handle support 10 . The mass balancing element 52 is designed to block a movement of the handle 4 out of its rest position when an inertial force acts on the handle 4 in the event of a vehicle accident. More precisely, this is Mass balancing element 52 is designed as a one-armed lever 53 which is rotatably mounted on the base plate 11 . In this case, the mass balancing element 52 is rotatably mounted about the articulation axis 36 which is arranged on the base plate 11 and via which the mounting lever 14 is connected to the base plate 11 . In order to compensate for inertial forces in the event of a vehicle accident, it is advantageous if the articulation axis 36 is arranged between the actuation axis 19 and the extension axis 16 . The mass balancing element 52 has a mass body 54 arranged at a distance from the joint axis 36, the one-armed lever 53 with the mass body 54 extending parallel to the base plate 11 and in a direction pointing away from the extension axis 16 (see for example figure 30 ). Furthermore, the mass balancing element 52 has an elastically deformable alignment element 55 which urges the mass balancing element 52 in the direction of the handle 4 . The elastically deformable alignment element 55 is designed as a torsion spring 56, which is wound around the hinge axis 36 and of which a first spring leg 57 is supported on the base plate 11 and a second spring leg 58 is supported on the mass balancing element 52 (see, for example Figures 30 and 32 ). The base plate 11 has a stop face 59 . The elastically deformable alignment element 55 presses the mass body 54 at least in sections against the stop surface 59 which is arranged between the handle 4 and the mass body 54 . With the aid of the stop surface 59 , the mass body 54 and the mass balancing element 2 are mounted pivotably about the joint axis 36 exclusively in a direction pointing away from the handle 4 . A contact surface 60 is formed on the mass body 54 and is aligned with a contact point 61 formed on the handle 4 (see, for example, Figures 31 and 33 ). The contact surface 60 protrudes through a recess formed in the base plate 11 and extends in direction of the contact point 61 of the handle 4. In the event of an inertial force acting in the event of a vehicle accident, the contact point 61 of the handle 4 comes into contact with the contact surface 60, which prevents the handle 4 from pivoting out in the deployment direction 12. To increase the effect of the mass balancing element 52, the contact surface 60 is designed to rise in a ramp-like manner in a direction pointing away from the joint axis 36, as is the case, for example, in FIGS Figures 31 and 32 can be seen. The mass balancing element 52 is thus designed to move with the base plate 11 and is mounted on the base plate 11 .
