Description

Door handle assembly for a motor vehicle

The invention relates to a door handle arrangement for a motor vehicle, comprising a handle bracket, a handle and a base plate movably mounted on the handle bracket, which is movable relative to the handle bracket and on which the handle is relatively movable with respect to the base plate, the Handle can take at least one rest position and one handling position, in which the handle, when installed in a vehicle door, is arranged for actuation relative to an outside of the vehicle door in an opening direction, and wherein the base plate on the handle support from a rest position, in which the handle 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.

Door handle arrangements for a motor vehicle can be designed as an inside or outside handle, the present invention relating to a door handle arrangement for an outside handle. For such door handle assemblies, there are a variety of different designs and embodiments in which, for example, the handle support on the back of the

Vehicle door, i.e. is attached to the inside of the motor vehicle. In such embodiments, the handle attached to the handle support usually protrudes from the vehicle door and disturbs both the aesthetic impression of the motor vehicle and 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, is almost flush with the surface

The outer contour of the vehicle door, i.e. flush with the edges, runs. Such a handle is for opening the vehicle door in one Handling position transferable, in which the handle

protrudes from the outer contour of the vehicle door and can be gripped and pivoted by a user to the

Open vehicle door.

Such a door handle arrangement is for example for

Electric cars from Tesla Motors Inc. and from DE 10 2013 212 198 Al are known. This known door handle arrangement has a handle which is arranged flush in its rest position and which moves from the rest position into a handling position

is motor-driven movable. Such a handle will

preferably used in electric cars in which the handle extends exclusively to a power-operated drive from its flush or flush rest position, in which the handle is arranged to reduce air resistance, into the handling position when a legitimate operator approaches the motor vehicle. As soon as the handle is no longer needed, it returns to the rest position and thus disappears in the body so as not to create any air resistance.

Furthermore, constructions of

Door handle arrangements of the type described in the introduction are known, in which the handle is movably mounted on a base plate, the base plate in turn being movably mounted on a handle support in an opening 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 comes into an extended position with respect to the vehicle door. In this extended

Position, a user can then reach behind the handle to open the vehicle door. For these constructions known to the applicant, the measures for securing the base plate and the handle in the event of a vehicle accident are very complex and require a large amount of installation space in order to permit the undesired extension of the

Base plate or an unwanted swinging out of the handle in a vehicle accident as a result of acting on the handle Avoid inertia forces, taking into account functional sequences for normal operation and emergency operation of the door handle arrangement, which increases the complexity of the construction.

The invention has for its object to provide a solution which provides an improved door handle arrangement for a motor vehicle and in particular an innovative concept in a structurally simple manner in order to prevent unwanted opening of the vehicle door in the event of a vehicle accident.

In a door handle arrangement of the type described in the introduction, the object is achieved according to the invention in that a

Mass balancing element is mounted on the base plate movably mounted on the handle support, which moves the handle out of its rest position when the handle is on the

Handle acting inertia is designed to block a vehicle accident.

Advantageous and expedient configurations and

Further developments of the invention result from the

Subclaims.

The invention provides a door handle arrangement for a motor vehicle, which is characterized by a simple construction and a special concept

Securing the door handle arrangement against an undesired opening of a vehicle door in the event of a vehicle accident under the action of inertial forces on the door handle arrangement. The securing device according to the invention allows the handle to be mounted on a base plate, which is moved from a rest position into a working position for actuating the handle, the

Handle is moved with the base plate and is pivotally mounted on this. Just like the handle, the mass compensation element moves with the base plate.

In an embodiment, the invention provides that the handle is arranged on the base plate in a non-pivoted manner in the rest position and in the handling position, the handle being through a user manually from the handling position into a

Operating position movable to open the vehicle door

is formed, and wherein the handle in the

Handling position is pivoted relative to the base plate.

It is structurally particularly favorable if that

Mass balancing element is designed as a one-armed lever which is rotatably mounted on the base plate.

It is further provided in an embodiment of the invention that the mass balancing element by one on the base plate

arranged hinge axis is rotatably mounted. The hinge axis is the articulated connection of a bearing lever and the base plate, so that an existing axis

is used simultaneously for the mass balancing element.

Accordingly, the invention sees further

Design before that the base plate over a

Storage lever is connected to the handle bracket and the

Handle over an arranged on the base plate

Actuating axis is pivotally mounted, the

Storage lever around an arranged on the handle bracket

Extending axis is rotatably mounted. The storage lever is used to extend the base plate.

It is particularly favorable to compensate for all moments acting in a vehicle accident if the joint axis is arranged between the actuation axis and the extension axis.

The invention further provides an embodiment of the

Door handle arrangement that the mass balancing element has a mass body arranged at a distance from the hinge axis and an elastically deformable alignment element

Mass compensation element in the direction of the handle.

In an embodiment of the invention, a simple and effective measure is provided in that the elastically deformable alignment element is designed as a torsion spring, which is wound around the hinge axis and of which a first spring leg on the base plate and a second

Support the spring leg on the mass compensation element.

In order that the mass balancing element can lose its maximum effectiveness and is held in a position necessary for this purpose, the invention provides that the

Base plate has a stop surface, wherein the elastically deformable alignment element presses the mass body at least in sections against the stop surface, which is arranged between the handle and the mass body.

It is particularly favorable in terms of construction and utilizes the installation space if, in an embodiment of the invention, the mass body

is only pivotally mounted in a direction pointing away from the handle about the hinge axis.

For a targeted action on the handle in the event of a vehicle accident, it is in an embodiment of the invention from

Advantage if a contact surface is formed on the mass body, which is designed to be aligned with a contact point formed on the handle.

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

According to the invention, the handle when installed in a vehicle door in the rest position can be arranged flush with the outside of the vehicle door or opposite to it

Outside of the vehicle door in an opening direction in a position not operable for an operator

be arranged. Both positions have aerodynamic advantages over a handle that is permanently arranged in the handling position.

It is understood that the above and

The following features to be explained not only in the combination given in each case, but also in others

FIG. 1 shows an example of a motor vehicle 1 in the form of a car, which in the example has four vehicle doors 2 (two of which are shown in FIG. 1). has a respective door handle arrangement 3 and

can be opened in particular with the aid of a handle 4 of the door handle arrangement 3. The vehicle doors 2 are firmly closed by means of a respective door lock 5 and can only be opened from the outside by a respective movement of the handle 4. In 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 microswitch, 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 case 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 an operator actuating the handle 4. In emergency operation, the corresponding movement of the handle 4 is applied to the corresponding lock 5 via a vehicle door opening means 6, which in the present case is a Bowden cable system

transfer. In the sense of the invention, normal operation is to be understood as an operating mode of the door handle arrangement in which the locking and unlocking of vehicle doors (and also flaps) is carried out purely electrically by means of a drive unit, the handle 4 also being electrically operated from a rest position into a handling position which a user the

Handle 4 to open the vehicle door 2 can be moved. Furthermore, in the sense of the invention, an electroless emergency operation is to be understood as an operating mode in which the vehicle electronics have failed (for example in the case of an empty vehicle battery) and the handle 4 has to be moved manually by a user into the handling position in a mechanical manner so that a user can operate the Handle 4 for unlocking and opening the vehicle door 2 can operate.

Figure 2 shows a perspective view of one of the

Vehicle doors 2 and the handle 4 used to open the vehicle door 2. FIG. 2 shows the handle 4 - when the Door handle arrangement 3 in the vehicle door 2 - approximately flush with the outside 7 of the vehicle door 2, ie flush with the edge or

flush, arranged. 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 in their rest position. Rather, the invention additionally encompasses embodiments in which the handle 4 is arranged so that it is exposed to the outside 7 of the vehicle door 2 in such a way that the handle 4 is nevertheless not operable or manageable for an operator because the handle 4 is in this position by one Operator cannot be accessed. From that shown in Figure 2

In the rest position, the handle 4 can be moved into a handling position shown in FIG. 3, in which it protrudes from the outside 7 of the vehicle door 2. So it is

Handle 4 arranged in its handling position protruding from the vehicle door 2. In this handling position protruding or extended from outside 7, an operator can reach behind and actuate or manipulate handle 4 in order to open vehicle door 2. According to the present invention, the handle 4 is transferred from the rest position into the handling position by means of a mechanical adjusting element 8, which is moved in normal operation by a drive motor 9 (see for example FIGS. 6 and 7). It can for the

Normal operation proximity sensors or other sensors

be provided in order to put the drive motor 9 into operation 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. For this purpose, proximity sensors known from the prior art can be installed in the handle 4, which transmit a signal to a vehicle control device when an authorized operator or ID transmitter is recognized send, whereby the drive motor 9 is put into operation and ensures the issuing of the handle 4 in the handling position.

The door handle arrangement 3 according to the invention comprises the

Handle 4 and a handle bracket 10, which can be attached to the inside of the vehicle door 2. The handle bracket 10 supports or supports the other components of the door handle arrangement 3, wherein other components can also be attached to the handle bracket 10. In this case, the drive motor 9 can be fastened to the handle support 10 or to the vehicle door 2 or in the region of the vehicle door 2. In Figures 2 and 3, the handle bracket 10 is behind the

Recognizable outside 7 of the vehicle door 2. As can be seen from FIGS. 4 and 5, there is one on the handle support 10

Base plate 11 mounted, which is movable relative to the handle bracket 10 and on which the handle 4 is mounted. Figures 4 and 5 show quasi-transparent views of the

Door handle arrangement 3, in FIG. 4 the base plate 11 in a rest position and at the same time the handle 4 mounted on the base plate 11 in its rest position, whereas in FIG. 5 the base plate 11 in a working position and at the same time the handle 4 mounted on the base plate 11 their handling position are arranged. As the comparison of the different positions of the base plate 11 and the handle 4 in FIGS. 4 and 5 shows, the handle 4 is arranged on the base plate 11 without moving when the base plate 11 moves from the rest position into the working position. Consequently, the handle 4 from a movement of the base plate 11

Rest position in the handling position with the base plate 11 without the handle 4 relative to the

Base plate 11 moves. 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 opening direction 12, for example from the

Figures 4 and 5 can be seen.

In FIG. 5, the base plate 11 is moved from its rest position shown in FIG. 4 in its working position, so that the handle 4 is in its rest position

Handling position is arranged moved. These situations are shown again in FIGS. 10 and 11, only the handle 4, a positioning lever 14 and a movement lever 15 being shown here as components of the door handle arrangement 3. The storage lever 14 and the movement lever 15 are used for

Issuing the base plate 11, wherein the bearing lever 14 is rotatably mounted about an extension axis 16 arranged on the handle bracket 10, whereas the movement lever 15 is rotatably mounted about a pivot axis 17 arranged on the handle bracket 10. In normal operation, the drive motor 9 shown for example in FIGS. 6 and 7 is in operation and moves it

Adjusting element 8, which in turn acts on the storage lever 14 and rotates it about the extension axis 14, as a result of which the base plate 11 reaches the working position shown in FIG. 11 from the rest position shown in FIG. 10. The base plate 11 is consequently articulated via the bearing lever 14 and also the movement lever 15 to the handle support 10, only the bearing lever 14 being driven in order to move the base plate 11. The movement of the storage lever 14 is transmitted to the movement lever 15 via the base plate 11 and a transmission bracket 18 extending parallel to the base plate 11 (see for example FIG. 7). Thus, the base plate 11 on the handle bracket 10 from the rest position in which the

Handle 4 is arranged in its rest position, in the

Working position in which the handle 4 in its

Handling position is arranged, designed to be movable, the handle 4 being arranged in the handling position when installed in a vehicle door 2 for actuation in the opening direction 12 relative to the outside 7 of the vehicle door 2 is as shown in Figure 11. In the rest position of the base plate 11, which is mounted so as to be movable relative to the handle support 10

Positioning lever 14 is arranged in a retracted position (see FIG. 10), whereas in the working position of base plate 11, positioning lever 14 is arranged in an extended position (see FIG. 11). In FIG. 12, the handle 4 is now pivoted out of the handling position shown in FIG. 11 into an operating position, which is done by an operation by a user pulling on the handle 4. The operating position of the handle 4 shown in FIG. 11 is only intended to demonstrate the pivotability of the handle 4 on the base plate 11 as an example. In normal operation, a pivoting of the handle 4 of 2 ° is sufficient for a microswitch

electrical opening of the vehicle door 2 is actuated, whereas in an emergency operation a larger stroke or a pivoting of the handle 4 by a larger angle causes that

Bowden cable system 6 is used to mechanically open the vehicle door 2. The handle 4 is pivotally mounted on an actuating axis 19 arranged on the base plate 11, as shown for example in FIG. It follows from FIGS. 10 to 12 that the handle 4 is not pivoted on the base plate in the rest position and in the handling position

11 is arranged, wherein the handle 4 is designed to be movable manually by a user from the handling position into the actuating position for opening the vehicle door 2, the handle 4 in the actuating position relative to the

Base plate 11 is arranged pivoted. The handle 4 is constructed in several parts, which can be seen, for example, from FIG. 8, and comprises an aperture body 20 and one of them

Panel body 4 in the assembled state at least partially covered main body 21, wherein in the illustration of the figure

12, the diaphragm body 20 is shown transparently so that the extension axis 16 can be seen. After the basic operation of the door handle assembly 3 for an opening and a

Operation of the handle 4 has been described in very general terms, the special features according to the invention, which are used to block or block the extension movement, will now be discussed

are responsible so that in the event of a vehicle accident as a result of inertial forces acting on the door handle arrangement 3, the base plate 11 does not undesirably move into its extended position

extends and the handle 4 is undesirably pivoted into an operating position. A distinction is made below between normal operation and emergency operation of the door handle arrangement 3 as well as between locking or blocking of the base plate 11 and the handle 4.

Figures 24 to 29 focus on the blocking of the base plate 11 in its rest position and on the lifting of the

Blocking in order to be able to operate the handle 4, FIGS. 25 and 26 relating to normal operation of the

Door handle arrangement 3 and Figures 27 to 29 on one

Relate emergency operation of the door handle arrangement 3.

In FIG. 24, the door handle arrangement 3 is not in operation and the base plate 11 is secured to the handle support 10, so that the base plate 11 remains in its rest position in the event of a vehicle accident. In the rest position of the base plate 11 is one

Storage lever lock 22 engages with the storage lever 14 and blocks movement of the storage lever 14 out of the

Retracted position. The storage lever lock 22 is shown in more detail, for example, in FIGS. 17 and 18 and is designed in the form of a one-armed lever, the storage lever lock 22 being mounted on the handle support 10 so that it can rotate about a locking axis 23. The storage lever lock 22 is about the locking axis 23 in a locking division in which the

Storage lever lock 22 is engaged with the storage lever 14, and in a release position in which the

Storage lever lock 22 with the storage lever 14 except Engagement and the storage lever 14 releases, rotatably mounted on the handle bracket 10. The storage lever lock 22 is in Figure 24 in the locking division, the

Figures 17 and 18 show this situation for the storage lever 14 and the storage lever lock 22. For blocking or

Locking a movement of the base plate 11 out of the rest position, a locking hook 24 is formed on the storage lever lock 22, which one in the locking division

Storage lever 14 trained latch 25

engages that the storage lever lock 22 den

Storage lever 14 holds in the retracted position. This engagement position is shown in FIGS. 17 and 18, FIG. 18 being a sectional view. The storage lever lock 22 is spring-loaded in the direction of the storage lever 14, so that it can be seen that the spring force is to be dimensioned such that it withstands an inertial force acting in the event of a vehicle accident.

To remove this block or block the

Storage lever 14 in a normal operation of the door handle assembly 3 is the approach of an authorized user

Drive motor 9 put into operation, which in turn

Control element 8 moves. The drive motor 9 rotates this

Control element 8 clockwise around a drive shaft 26 mounted on the handle support 10, so that the motor

driven adjusting element 8 moves or rotates from a zero position shown in FIG. 24 into a normal operating position shown in FIG. The rotation of the actuator 8 from the

Zero position in the normal operating position causes two aspects, which take place one after the other. By rotating the control element 8 from the zero position, the control element 8 first moves the storage lever lock 22 out of the locking division into the

Release position, which can be seen from Figure 25. To the

Storage lever lock 22 from the locking division in the

To move release position is on the control element 8 Movement circumference contour 28 formed, which can be seen from Figures 13 and 14. The circumferential movement contour 28 has a neutral circumferential section 29 and an unlocking circumferential section 30. The unlocking circumferential section 30 is formed with a greater distance 31 (see, for example, FIG. 14) from the drive axis 26 than the neutral circumferential section 29. This larger distance 31 results from the fact that the neutral circumferential section 29 as a notch or an incision in the circumferential wall of the circumferential movement contour 28 in the shown

Embodiment is formed, whereas the

Unlocking peripheral portion 30 of the peripheral wall of the

Circumference of movement contour 28 corresponds, which runs in a circle on a constant radius. In the locking division is one of the storage lever lock 22 in the direction of the actuating element 8

protruding approach 32 with its free end in the as

Notch formed neutral peripheral portion 29 is arranged. If the actuating element 8 is now rotated about the drive axis 26 by the drive motor 9, then the neutral peripheral section 29 moves away from the shoulder 32 of the bearing lever lock 22 and the shoulder 32 bears against the unlocking peripheral section 30, due to the larger radius of the unlocking circumferential section 30, 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 latching hook 24 is excluded

Engages with the locking projection 25. In other words, in the zero position of the actuating element 8, the storage lever lock 22 bears against the neutral peripheral section 29 and is in the position shown in FIG

Locking division arranged, whereas in the normal operating position of the actuator 8, the storage lever lock 22 of the

Unlocking peripheral portion 30 in the release position

is crowded. Accordingly, the actuator 8, the storage lever lock 22 from the locking division in the

Release position designed to be moving by the actuating element 8 during its movement from the zero position into the normal operating position, the spring-loaded storage lever lock 22 urges in a direction pointing away from the storage lever 14. Thus, the storage lever lock 22 releases the storage lever 14, which does not move automatically into the extended position, since a lever return spring 27 (see for example FIGS. 7, 21 and 30) on the storage lever 14 one in the direction of the

Retracting position exerts force. In a step following the release of the storage lever 14, the actuating element 8 ensures that after the storage lever 14 is released by moving the storage lever lock 22 into the release position of the

Positioning lever 14 is moved into the extended position, so that after the two steps, all the components mentioned assume the positions shown in FIG. 25. So that

Storage lever 14 is transferred into its extended position and thereby the base plate 11 in the working position and the handle 4 in its issued handling position, a driver contour 33 is formed on the actuating element 8 (see

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 urges it when the adjusting element 8 rotates into the extended position. The storage lever 14 is also 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 articulated axis 36, as shown for example in FIGS. 10 to 12. Thus, when the control element 8 moves from the zero position into the

Normal operating position, the driver contour 33 pressing against the second lever arm 35 and the storage lever 14 from the

Retracted position in the extended position moving. As can be seen from FIG. 16, the driver contour 33 is axially and circumferentially offset from the circumferential movement contour 28 on the actuating element 8 with respect to the drive axis 26

educated. So that of the actuator 8 first Storage lever lock 22 is moved out of the locking division and then the storage lever 14 is moved into the extended position, the driver contour 33 is circumferentially offset from the movement circumference contour 28 on the actuating element 8, so that first the movement circumference contour 28 on the

Storage lever lock 22 acts and then after the movement of the storage lever lock 22 from the locking division 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 expose the handle 4 quickly, the driver contour 33 is at a greater radial distance 37 from the drive axis 26 than that

Circumference of movement contour 28 is formed, as in FIG. 16

can be seen. From the position shown in FIG. 25, the handle 4 can now be gripped by a user in a normal operation of the door handle arrangement 3 and pivoted to open the vehicle door 2, wherein a pivoting of about 2 ° about the actuation axis 19 is sufficient in normal operation to achieve one Micro button for electrical door opening

activate. As can be seen from FIG. 26, the positioning lever lock 22 remains in the operating position shown in FIG. 26 even when the handle 4 is moved

Release position. The storage lever lock 22 does not return to the locking position until the actuating element 8 moves back into its zero position, in which the storage lever lock 22 then engages with the storage lever 14, the two described above also being used here

Unlocking and issuing steps are followed, but in reverse order.

FIGS. 27 to 29 show a currentless emergency operation of the door handle arrangement 3 when the vehicle electronics do not work, for example due to an empty vehicle battery, and the actuating element 8 for electrically opening a vehicle door 2 cannot be put into operation. 24 To remove the shown blocking or blocking of the base plate 11, the door handle arrangement 3 is designed such that a user can move the handle 4 inwards against the opening direction 12 in an emergency. Such a position is shown in FIG. 27, in which the handle 4 is arranged against the opening direction 12 when the door handle arrangement 3 is operated in an emergency. The inward movement of the handle 4 is possible because the

Actuating axis 19, about which the handle 4 is pivotally mounted on the base plate 11, against one of one

Restoring element 38 exerted restoring force against

Display direction 12 is movably mounted on the base plate 11 (see Figure 9). The base plate 11 has two bearing arms which extend in the direction of the opening direction 12, the two bearing arms 39 being inserted into corresponding receptacles in the handle 4 and being articulated there with the handle 4. The restoring element 38 is designed to be elastically deformable and, in the exemplary embodiment, in the manner of a

Torsion spring executed, the restoring element 38 in a receiving space 40 from one of the two bearing arms 39

is housed and against the actuation axis 19 in the

Display direction 12 presses. So that the movement of the

Actuating axis 19 is guided against the opening direction 12, a guide recess 41 is formed in the bearing arm 39, in which the actuating axis 19 delimits

is movable. Through this inward movement of the

Handle 4 or when the actuation axis 19 moves out of the opening direction 12, which is shown in FIG. 27, an actuation projection 42 formed on the handle 4 (see for example FIGS. 8 and 20) comes into contact with one another

Blocking 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 bracket 10. The blocking lever 43 is between one Blocking position and a neutral position movable. In FIG. 24, in which the base plate 11 is blocked or locked in an extending movement on the handle support 10, the blocking lever 43 is arranged in its blocking position, whereas, due to the inward movement of the handle 4, the actuating projection 42 moves the blocking lever 43 out of its blocking position moves its neutral position, this movement being a pivoting movement about the lever axis 44, by means of 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 tends to hold the blocking lever 43 in its blocking position or to push it back into its blocking position. By moving the blocking lever 43 from a

Blocking position in its neutral position is also the storage lever lock 22 from its locking division in their

Release position moved. As can be seen, for example, from FIG. 23, the free end of the storage lever lock 22 lies on a side of the handle 4 facing away from the handle 4

Blocking lever 43 on, so that a movement of the

Blocking lever 43 in a direction pointing away from the handle 4 also moves the storage lever lock 22 in a direction pointing away from the handle 4, as shown in FIG. 27. This urges when the blocking lever 43 moves from its blocking position into its neutral position

Blocking lever 43 in the direction of its locking division

spring-loaded storage lever lock 22 in the by the

Storage lever 14 pioneering release position. As a result, the positioning lever 14 is released in its movement since the

Storage lever lock 22 now in its release position

is arranged. But since the storage lever 14 by the

Lever return spring 27 is held in its retracted position, an emergency extension element 45 is provided for extending the base plate 11 in emergency operation of the door handle arrangement 3. The emergency exit element 45 is rotatably mounted on the handle support 10 between a basic position (see FIG. 24) and an emergency operating position (see FIG. 27), the emergency exit element 45 being mounted on the exit axis 16 in the exemplary embodiment shown, on which the bearing lever 14 is also mounted . The emergency extension element 45 is the storage lever 14 in its movement into the emergency operating position

Extending position is designed to be moving. The emergency exit element 45 is designed with a control lever arm 46, a free end of which rests on the blocking lever 43 in the rest position of the base plate 11 and is held blocked in the basic position by the blocking lever 43. In other words, it lies

Blocking lever 43 in the basic position on the control lever arm 46 and blocks a movement of the emergency exit element 45 in the direction of the emergency operating position. Due to the movement of the blocking lever 43 caused by the handle 4 out of it

The blocking position returns to its neutral position in

In the direction of the handle 4, spring-loaded blocking lever 43 releases the emergency extension element 45 for movement from the basic position into the emergency operating position. As can be seen from FIGS. 24 to 26, the blocking lever 43 is in one

Normal operation of the door handle assembly 3 in its

Arranged blocking position, the blocking lever 43 holds the emergency exit element 45 in the basic position. In FIG. 27, the emergency extension element 45 is now free for the currentless emergency operation to move in the direction of its emergency operating position, the emergency extension element 45 being in the direction of its

Emergency operating position is spring-loaded. 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 located both on the handle support 10 and on the emergency extension element 45

support. As can be seen from FIG. 21, for example a driver element 48 is formed on the control lever arm 46 of the emergency exit element 45. The driver element 48 comes out of the movement of the emergency exit element 45

Basic position in the emergency operating position in the system

Storage lever 14 and urges the storage lever 14 in the

Extended position, as shown in FIG. 28, 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 dimensioned larger than the force of the lever return spring 27.

So that the base plate 11 is not moved beyond the extended position, a stop lever 49 is formed on the emergency extension element 45. The stopper lever 49 moves at one

Movement of the emergency extension element 45 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 lies against a stopper contour 50 formed on the actuating element 8, as shown in FIGS. 22 and 28. On the above

described way is in a de-energized emergency mode

Handle 4 issued manually by a user via the base plate 11, so that the handle 4 can now be actuated and pivoted in emergency operation, as shown in FIG. Due to the pivoting of the handle 4 by a user, a Bowden cable lever 51 is used in the manner of a

Bowden cable trained vehicle door opening means 6 actuated to open a vehicle door 2 in emergency operation.

FIGS. 30 to 33 are aimed at compensating an inertia force acting on the handle 4, for example in the event of a vehicle accident, in order to prevent the handle 4 from swinging out unintentionally. For this purpose, a mass compensation element 52 is mounted on the base plate 11 movably mounted on the handle support 10. The mass compensation element 52 is a movement of the handle 4 out of its rest position at one on the

Handle 4 acting inertia trained in a vehicle accident blocking. More specifically, it is Mass balancing element 52 formed as a one-armed lever 53 which is rotatably mounted on the base plate 11. In this case, the mass balancing element 52 is around the

Base plate 11 arranged pivot axis 36 rotatably, via which the storage lever 14 is connected to the base plate 11. To compensate for inertial forces in the event of a

It is advantageous in the event of a vehicle accident 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

extends parallel to the base plate 11 and in a direction pointing away from the extension axis 16 (see, for example, FIG. 30). Furthermore, the mass compensation element 52 has an elastic

deformable alignment element 55, which the

Mass balancing element 52 urges 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 on the base plate 11 and a second spring leg 58 on the

Support mass balancing element 52 (see for example Figures 30 and 32). The base plate 11 has a stop surface 59. The elastically deformable alignment element 55 presses the mass body 54 against the at least in sections

Stop surface 59, which between the handle 4 and the

Mass body 54 is arranged. With the help of the stop surface 59, the mass body 54 and the mass compensation element 2

only pivotably mounted in a direction pointing away from the handle 4 about the hinge axis 36. In this case, a contact surface 60 is formed on the mass body 54, which leads to a contact point 61 formed on the handle 4

is aligned (see for example Figures 31 and 33). The contact surface 60 projects through a recess formed in the base plate 11 and extends in the direction of the contact point 61 of the handle 4. In the case of one acting by an inertial force 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 opening direction 12. To increase the effect of the mass compensation element 52, the contact surface 60 is designed to rise in a ramp shape in a direction pointing away from the joint axis 36, as can be seen for example in FIGS. 31 and 32. The mass compensation element 52 is thus designed to move with the base plate 11 and on the

Base plate 11 stored.
