Description

Door handle assembly for a motor vehicle

The invention is directed to a door handle assembly for a motor vehicle having an inside on a door or

Flap of the motor vehicle fastened handle support, a to

Opening the door or flap of the motor vehicle serving handle in a rest position flush with the door or flap and in an actuated position from the door or flap

is arranged protruding, a handle from the

Resting position in the operating position and back moving lever element, the first longitudinal end pivotally mounted on the

Handle carrier is mounted and the second longitudinal end of the

Handle stores, and a transmission element, which is movably mounted on the handle support and with the lever element

is operatively connected, being for a current-driven

Normal operation, the transmission element from a basic position to a first normal operating position, in which the

Transmission element moves the handle on the lever member in the actuation position, purely driven electrically driven is formed, and wherein an actuation of the in their

Operating position arranged handle opens a vehicle-side lock.

Such door handle assemblies for a motor vehicle may be designed as an inner or outer handle, wherein the present invention relates to a door handle assembly for a

External handle refers. Such door handle assemblies have a variety of different constructions and embodiments. The execution of a door handle according to the invention relates to such constructions in which the handle support on the

Rear of the door, i. inside the motor vehicle,

is attached. The handle attached to the handle support is in such embodiments usually protruding from the door and disturbs both the aesthetic impression of the vehicle and the vehicle aerodynamics. To these disadvantages too

avoid, are from the prior art door handle assemblies known in which the outside of the handle in its rest position, in which it is not needed, approximately flush with the outer contour of the door, so strakbündig runs. Such a handle is for opening the door or a

vehicle-mounted lock in an operating position

convertible, in which the handle protrudes from the outer contour of the door.

A door handle assembly of the type referred to input is known for example for electric cars Tesla Motors Inc. and DE 10 2013 212 198 AI. This known

Door handle assembly has a flush in its rest position arranged handle, which from the rest position in a

Actuating position is motor-driven movable. Such a handle is preferably used in electric cars, in which the handle extends exclusively with a current-driven drive from its strakbündigen rest position, in which the handle for reducing the air resistance is disposed in the actuation position when a legitimate user approaches the vehicle. Once the handle is no longer needed, it returns to the rest position and

thus disappears in the body, so as not to create air resistance. The disadvantage is that the handle can not be moved in case of failure of the motor drive and opening a door is almost impossible, what

safety reasons is quite problematic.

The invention has for its object to provide a solution in a structurally simple way a

Door handle assembly provides that are inexpensive in their

Production is and in which the handle can be moved even in case of failure of the motor drive and can be actuated to open the door.

In a door handle assembly of the type described input, the object is achieved in that for a powerless emergency operation, the transmission element from the

Basic position in an emergency operating position, in which the

Transmission element, the lever element at least for moving the Handle pivoted into the actuation position, is designed to be movable.

Advantageous and expedient embodiments and

Further developments of the invention will become apparent from the

Dependent claims.

The invention provides a door handle assembly of a

Motor vehicle provided, which is characterized by a functional design and has a compact and inexpensive construction. In the door handle assembly according to the invention, the movement of the transmission element in both the normal operation mode and the non-current emergency mode ensures that the handle is in the operating position in which it protrudes from the door or flap of the vehicle and operated by a user can to open the vehicle-side lock. With the door handle assembly according to the invention, it is consequently possible to open the door or flap of the vehicle purely manually even in the event of failure of the electrical supply. As a result, even in an emergency, such as a powerless emergency operation, a full

Functionality of the door handle assembly given and im

Normal operation nevertheless maintained the highest level of aerodynamic advantages.

A structurally particularly easy way to

Realization that an operation of the handle the

Vehicle-side lock opens, is in an embodiment of the invention in that a rotatably mounted on the handle support opening lever is coupled to the lock, wherein a

Actuation of arranged in its operating position

Handle moves the opening lever from a neutral position to an opening position opening the lock.

For the current-driven normal operation of the door handle assembly is provided in an embodiment of the invention that the

Door handle assembly has at least one drive which moves in the current-driven normal operation, the transmission element at least from the home position to the first normal operating position. Due to the current driven movement of the

Transmission element is the with the transmission element motion-coupled lever member pivoted at its first longitudinal end, whereby the handle is extended to the operating position and protrudes from the door or flap.

To increase the comfort of the door handle assembly according to the present invention, it is advantageous in another embodiment, if at least one proximity sensor is arranged in the handle and / or on the handle carrier, which is formed with the information-connected to the drive that in the current-driven normal operation of the proximity sensor at

Detecting the approach or touch of a legitimate user activates the drive and this then the

Transmission element from the basic position to the first

Normal operating position moves.

In the door handle assembly according to the invention, the comfort can be further increased when in the power-driven

Normal operation of at least one proximity sensor

Approaching or touching a legitimized or authorized user reverses the lock from a locked position to an unlocked position. This allows keyless access for the vehicle.

In order that the user in the current-driven normal operation does not have to apply a high manual force in order to open the lock, the invention provides in a further embodiment that a detection means is provided, which is formed in an information-connected manner with the drive in such a way

current-driven normal operation upon detection of a manual operation arranged in its operating position

The detecting means has at least one drive for moving the transmission element out of the first one

Normal operating position in a second normal operating position, in which the transmission element cooperates with the vehicle-side lock opening lever opens, activated. The opening of the castle is accordingly in the current-driven

Normal operation by means of the drive, which further increases the comfort for the user.

A structurally particularly compact and space-saving

Execution is for the door handle assembly according to the invention in Another embodiment possible in that the opening lever is rotatably mounted on a rotatably mounted on the handle carrier gear, wherein the gear with a on the

Transmission element mounted rack engages.

In a further embodiment, it is advantageous if, during a movement of the transmission element from the first to the second normal operating position, the movement of the transmission element at least for a part of its movement path

Rack drives the gear and urges the opening lever in the open position. A movement of the transmission element in the current-driven normal operation accordingly moves the

Rack, whereby the gear meshing with the rack gear is rotated, on which the opening lever rotatably

is fixed, so that ultimately pivots the opening lever in its open position and thereby opens the lock.

The transmission element moves from the home position over the first normal operating position to the second

Normal operating position along the handle carrier, but with a movement coupling between the transmission element and the rack (ultimately for the deflection of the opening lever) only between the first and second normal operating position, but not between the basic position and the first

Normal operating position is desired. For this reason, the invention provides in a further embodiment of the door handle assembly that the rack has a movement pin which is inserted in a recess in the transmission element, wherein the rack is movable relative to the transmission element in the recess.

The invention provides in a further embodiment that the transmission element is biased in the direction of the first emergency operating position and a locking means pivotally mounted on the

Bearing element is mounted, which blocks a movement of the transmission element from the basic position in the direction of the emergency operating position in a latching position. The

Transmission element is thus in the direction of

Emergency operating position biased, including, for example

Spring element can be used, thus in the de-energized Emergency operation an automatic movement of the transmission element from the home position is possible.

In a further embodiment of the invention, it is provided that the handle in the currentless emergency operation from the straight-line rest position in an engaged in the door or flap

Unlocking position is movable. For example, that can

Locking means have been moved in the unlocked position from its locking position, so that a movement of the

Transmission element in the direction of the emergency operating position is possible.

So that this movement of the transmission element is controlled in the direction of the emergency operating position and not accidental, is provided in an embodiment of the invention that in the

Entriegelungsposition a trained on the lever element

Entriegelungsansatz extending beyond the first longitudinal end, which defines a pivot axis for the lever member, away from the second longitudinal end, the locking means of his

Locking position urges, so that in the direction of the

Emergency operating position biased transmission element can move to the emergency operating position.

A structurally particularly simple way to extend the handle from its rest position, both for the current-driven normal operation and for the currentless emergency operation is that the transmission element at his

Moving from the basic position towards the first

Normal operating position the Entriegelungsansatz along a first Ausschwenkfläche and its movement out of the

Basic position in the direction of the emergency operating position

Entriegelungsansatz along a second Ausschwenkfläche such moves that the lever member about the pivot axis

pivots and moves the handle in the operating position. The respective Ausschwenkfläche the transmission element ensures that the lever member is pivoted and thereby exposing the handle so that it protrudes from the door or flap and can be handled by a user.

Accordingly, the invention provides further

Design of the door handle assembly that the first Ausschwenkfläche and the second Ausschwenkfläche each as an obliquely away from the handle carrier leading surface are formed, which urges the Entriegelungsansatz away from the handle support during movement of the transmission element in the first normal operating position or in the emergency operating position and thereby pivots the handle in the actuation position.

In order to open the lock of the door handle assembly in the currentless emergency operation, the invention provides in a further embodiment, that the handle coupled via a handling element with the opening lever so operatively connected or

is connected, that in the currentless emergency operation by an operation arranged in its operating position

Handle the handle the handling element against the handle

Opening lever urges and moves it from the neutral position to the open position.

Structurally, it is of particular advantage if the

Movements of the transmission element for both operating cases are substantially identical. Accordingly, the invention provides that the movement of the transmission element from the

Basic position at least in the first normal operating position is a linear movement, which is responsible for the movement of the

Transmission element from the home position extends at least in the emergency operating position in an opposite direction. Consequently, the home position represents a sort of mid-position from which the transmission element emerges, either in the

current-driven normal operation in the direction of the first

Normal operating position or moved in the current emergency operation in the direction of the first emergency operating position, wherein for both

Movements a single linear motion path is present and the basic position of the transmission element in the middle of the

Motion path is provided.

Finally, the invention provides in an advantageous manner that on the handle support an emergency lock cylinder is attached, which in the operating position of the handle from the outside for a mechanical emergency key to unlock the lock

is accessible. In this way, the lock can then be unlocked before it is to be opened manually. It is understood that the features mentioned above and below still to be explained not only in the combination given, but also in others

Combinations or alone, without departing from the scope of the present invention. The scope of the invention is defined only by the claims.

In Figure 1, a vehicle or motor vehicle 1 is exemplified in the form of a car, which in the example via four doors 2 (two of which are apparent from Figure 1), which has a door handle assembly 3 and in particular by means of a door handle or a Handle 4 can be opened. The doors 2 are firmly closed by a respective lock 5 and can only from outside via a respective

Movement of the handle 4 to be opened. This movement on the handle 4 may consist of a pulling and / or folding movement, wherein the corresponding movement of the handle 4 on the

corresponding lock 5 is transmitted. Through the movement of Handle 4 can be the corresponding lock 5 and thus the associated door 2 then open.

In Figures 2 to 23 is the inventive

Door handle assembly 3 in different views for different positions of the individual components to each other and for

various operating cases are described in more detail, which will be discussed in detail below.

Figures 2 and 3 show a perspective view of each of the door 2 and serving to open the door 2 handle 4. In Figure 2, the handle 4 is approximately flush with the outer contour of the door 2, so strakbündig arranged. In this position, she is in a rest position, in which she is not needed. From the rest position shown in Figure 2, the handle 4 can be converted into an operating position shown in Figure 3, in which the handle 4 protrudes from the outer contour of the door 2. Accordingly, the handle 4 is in her

Actuating position from the door 2 protruding arranged. In this protruding or extended operating position, a user can manipulate the handle 4 to open the door 2 and the vehicle-mounted lock 5, respectively. According to the present invention, the transfer of the handle 4 from the rest position to the operating position in either a current-driven normal operation by means of a suitable

Drive means or in a powerless emergency operation by means of manual operation by the user.

As can be seen, for example, in FIGS. 4 and 5, the door handle assembly 3 has a frame-like handle carrier 6. The grip carrier 6 is known to attach the

Handle 4, which is arranged in Figure 5 in its rest position. The handle carrier is by means not shown

Screw on the inside of the door 2, so

inside the door 2, attached. Here, the handle support 6 for reasons of material saving predominantly from a

Frame structure formed, which has various recording and storage areas to accommodate, among other things, the handle 4, which is intended to open a corresponding door 2 of the motor vehicle 1 and to open the vehicle-mounted lock 5. For example, the handle support 6 laterally next to the

Handle 4, a receiving chamber 7, in which an emergency lock cylinder 8 can be attached, so that the handle support 6, the emergency lock cylinder 8 is attached. The emergency lock cylinder 8 is accessible in the actuated position of the handle 4 from the outside for a mechanical emergency key to unlock the lock 5, such as Figure 3 shows.

As can be seen in particular FIG. 5, the handle 4 is not mounted directly on the handle support 6. Rather, the handle 4 is held by a lever element 9, which is H-shaped. Two bearing arms 10 of the H-shaped lever member 9 define a first longitudinal end 11 of the lever member 9, whereas two retaining arms 12 a second longitudinal end 14 of

Define lever element 9. Here, the first longitudinal end 11 and the bearing arms 10 of the lever member 9 is pivotally mounted on the handle support 6, so that the handle 4 can be moved by means of the lever member 9 from the rest position to the operating position and back. In particular, the two bearing arms 10 are pivotally mounted on the handle carrier via a pivot axis 21. In contrast, takes the second longitudinal end 14 and take the retaining arms 12 of the lever member 9, the handle 4.

Figure 5 also shows that on the handle support 6 a

Transmission element 15 is movably mounted. The

Transmission element 15 has a recess 17 into which a molded onto the handle support 6 rail 16, whereby the transmission element 15 is movable transversely to the handle support 6. The transmission element 15 is shown in detail in Figures 6, 7 and 8 and has a first Ausschwenkfläche 18 and a second Ausschwenkfläche 19, which is used to guide a on

Lever element 9 trained Entriegelungsansatzes 20 serve, which extends between the two bearing arms 10 and over the first longitudinal end 11 addition. The two Ausschwenkflächen 18 and 19 are particularly good in the plan view of the

Transmission element 15 can be seen in Figure 8.

Between the first Ausschwenkfläche 18 and the second Ausschwenkfläche 19, the transmission element 16 a Opening 22 (see Figure 7), in which a locking means 23 is pivotally supported. The locking means 23 can block a movement of the transmission element 15, what it with the

Handle carrier 6 is engaged, as will be described in detail below.

The transmission element 15 also has a recess 24 (see, for example, FIGS. 7 and 8), which in its

Top is formed. The recess 24 serves to receive a movement pin 25 which on the underside of a

Rack 26 is formed. Characterized the rack 26 is inserted with its movement pin 25 in the recess 24 and movable in the recess 24, so that the rack 26 can move relative to the transmission element 15 and also transversely to the handle support 6.

As further apparent from Figures 5 and 6, stands

Rack 26 with the teeth of a gear 27 in engagement. The gear 27 is rotatably mounted on the handle support 6 and formed only circular segment. The

circular segmental training is the compactness and

Reduction of installation space and is therefore possible because the gear 27 does not need to perform a complete revolution in its operation. On the gear 27 is also a

Opening lever 28 mounted rotatably, so that the opening lever 28, together with the gear 27 about the axis 29 of the

Gear 27 can rotate. As a result, the opening lever 28 is rotatably mounted on the handle support 6 and further coupled to the lock 5 via a Bowden cable 30 (see Figure 5). Of the

Opening lever 28 is movable from a neutral position into an opening position opening the lock 5.

A movement of the opening lever 28 from his

Neutral position in the lock 5 opening the opening position can be achieved by a movement of the rack 26 through which the gear 27 is rotated about the axis 29, whereby the rotatably mounted on the gear 27 opening lever 28th

is pivoted accordingly. The pivoting of the

Opening lever 28 can also with the help of a

Handling element 31 can be realized, which is movable the handle support 6 is held. More specifically, the handling member 31 extends within a guide channel 32 formed on the handle support 6 and a linear movement of the handling member 31 toward the opening lever 28

allowed. The handling element 31 is eccentrically attached to the gear wheel 27 at a first end and to the opening lever 28 at the end, so that a direction in the direction of the gear 27th

directed movement of the handling element 31 a

Pivoting of the opening lever 28 and at the same time

Rotation of the gear (with reference to Figure 5 opposite

Clockwise) causes.

On the transmission element 15, a drive angle 33 is also attached. The drive angle 33 is inserted laterally in holding means 35 of the transmission element 15 and with a

Actuator or actuator connected via the Bowden cable 34. The drive angle 33 serves to move the transmission element 15 in a current-driven normal operation, but for this purpose the locking means 23 must be arranged in its detent position, because the locking means 23 serves as a contact surface for the drive angle 33, otherwise in a pulling movement through the

Bowden cable 34 would be pulled out of the holding means 35. For an opposite movement, i. for a movement of the transmission element 15 with reference to Figure 5 to the left (ie, for a movement away from the gear 27), the

Drive angle 33 not determined. The drive angle 33 is determined only for a movement of the transmission element 15 to the right, ie in the direction of the gear 27.

The mode of operation of the door handle arrangement 3 according to the invention will now be described below, starting from FIGS. 1 to 8 already described above, together with FIGS. The door handle assembly 3 is characterized in that it can be used in addition to its current-driven normal operation even in an emergency in a powerless emergency operation for a user. For the currentless emergency operation to open the lock 5 is only a mechanical emergency key

required by an authorized or legitimate

User, of course, features. Figures 9 to 14 show different representations for the current-driven normal operation, wherein also different functional positions are shown. For example, in FIGS. 9 and 10, a basic position of the door handle assembly 3 is shown, in which the handle 4 is in a rest position that is flush with the outer contour of the door 2

Transmission element 15 of a basic position, the opening lever 28 in a neutral position and the locking means 23 in one

Detent position are located. In the basic position of

Transmission element 15 is the Entriegelungsansatz 20 centrally between the first and second Ausschwenkfläche 18, 19th

arranged so that the lever member 9 is not pivoted and consequently the lever member 9 holds the handle 4 in the rest position. In the latching position, the locking means 23 prevents a movement of the transmission element 15 which is directed away from the gearwheel 27. That is because by means of a spring element 36

Transmission element 15 biased in the direction away from the gear 27 direction, so that the locking means 23 prevents the spring element 36, the transmission element 15 pulls towards itself. The spring element 36 is attached at one end to the handle support 6, whereas the other end to the

Transmission element 15 is attached. The latching means 23 in its latching position, however, allows movement of the

Transmission element 15 in the direction of the gear 36, wherein the force of the spring element 36 is to overcome.

If the handle 4 is in the rest position and now an authorized or legitimate user

Vehicle or the handle 4 approaches, this is in

current-driven normal operation of the door handle assembly 3 detected by a proximity sensor 37. The proximity sensor 37 is shown schematically in Figures 10, 12 and 14 and arranged in the embodiment shown in the handle support 6, wherein alternatively an arrangement of the proximity sensor 37 in the handle 4 would be considered. Of the

Proximity sensor 37 is provided with a drive 38 which is a

Actuator or actuator can be and is shown only schematically in Figures 9, 11 and 13, information connected educated. This means that in the power-driven

Normal operation of the proximity sensor 37 upon detection of

Approaching or touching a legitimate user activates the drive 38 and then moves the transmission element 15 from the home position to a first normal operating position shown in FIGS. 11 and 12. In particular, the drive 38 pulls via a traction means at the drive angle 33, so that the transmission element 15 is moved to the first normal operating position. This movement of the transmission element 15 takes place counter to the force of

Spring element 36 and in the direction of the gear 27, as indicated by the arrow 39 in Figure 11. During the movement of the

Transmission element 15 in the first normal operating position, the first Ausschwenkfläche 18 comes into contact with the

Entriegelungsansatz 20 of the lever member 9. The first

Ausschwenkfläche 18 urges the Entriegelungsansatz 20 away from the handle support 6, whereby the lever member 9 to the

Swivel axis 21 pivots and the handle 4 in their

Actuator position moves. In the exhibited

Actuation position can now be a user, the handle 4

Press to open the door 2, leaving for the

current-driven normal operation, the issuing of the handle 4 in the operating position purely electrically by the drive 38 without the user has to expend force. As can also be seen from FIG. 11, during the movement of the transmission element 15, it moves from the basic position into the first position

Normalbetigungsposition the rack 26 relative to

Transmission element 15. The opening lever 28 is as good as not deflected in this movement - but at least the lock 5 is not opened when moving to the first normal operating position, because the deflection of the opening lever 28 to be seen in Figure 11 is not sufficiently large.

In order to open the lock 5, the user must actuate the handle 4 (see FIG. 12) arranged in the actuation position by turning it in the illustrated position

Embodiment pulls up. The handle 4 is therefore not only extendable by means of the lever member 9, but with Help a rocker arm 39 (see, for example, Figure 19) rotatable upwards or upwards, wherein alternatively also a downward rotational movement of the handle 4 is conceivable. The handle 4 is rotatably mounted on the first longitudinal end of the rocker arm 39, wherein a bearing pin 42 of the handle support 6 formed within a at the second longitudinal end of the rocker arm 39

Guide recess 41 is movable, whereby in particular the second longitudinal end of the rocker arm 39 is movable relative to the handle support 6 (see, for example, Figures 21 and 23, which show the tilting movement of the handle 4 for the currentless emergency operation, wherein the tilting movement for the current-driven

Normal operation is identical). The user does not have to pull excessively on the handle 4, so that the desired opening of the lock 5 takes place. Rather, it is enough an easy

Tilting movement arranged in the operating position

Handle 4 for example 1 °. Because of this easy

Tilting movement of the handle 4 is a detection means 43, which may be, for example, a micro-switch is actuated, which is information-connected to the drive 38, so that a

Actuation of the detection means 43, the drive 38 is activated. As a result, the drive 38 moves in the current-driven normal operation, the transmission element 15 from the first normal operating position to a second normal operating position (see, for example

Figures 13 and 14). By the further movement of the

Transmission element 15, which is indicated by the arrow 45, the Entriegelungsansatz 20 remains urged away from the handle support 6, but it is not pushed further in the movement from the first normal operating position to the second normal operating position. However, the moving pin 25 of the rack 26 is now in the movement of the

Transmission element 15 from the first to the second

Normal operating position at the left longitudinal end of the recess 24 in the transmission element 15, so that during the movement of the transmission element 15 in the direction of the arrow 45, the rack 26 is moved. During the movement of the transmission element 15 from the first to the second normal operating position then drives the transmission of the element 15 at least for a part of their Moving path mitbewegte rack 26, the gear 27 and urges the opening lever 28 in the open position. Thus, the gear 27, whose teeth are in engagement with the teeth of the rack 26, moves counterclockwise. The rotation of the gear 27 causes the rotatably mounted on the gear 27 opening lever 28 pivots. The

Pivoting movement of the opening lever 28 in turn causes a

Pulling on the Bowden cable 30 connected to the lock 5, whereby the lock 5 is finally opened. The drive 38 thereby moves the transmission element 15 until the

Opening lever 28 a microswitch 47 is actuated, which is coupled to the drive 38 such that the actuation of the

Microswitch 47 stops by the opening lever 47, the drive 38, whereby the opening process for the lock 5 in

current-driven normal operation is completed.

After the lock 5 is opened, the drive 38 can travel back again in the current-driven normal operation, so that the transmission element 15 is urged back in the direction of the basic position due to the force of the spring element 36.

For example, the drive 38 may retract so far that the opening lever 28 is again located in the neutral position, i. the transmission element 15 is in the first

Normal operating position moved back. In contrast, the

Door handle then still be exhibited and only on the basis of a signal of the vehicle 1, for example, due to a start of the vehicle engine, are returned to the rest position.

Should there be a failure of the electrical supply of the vehicle 1 or a failure of the motor drive 38, the transmission element 15 can not be moved to issue the handle 4 and the opening lever 28 to open the door 2 and the lock fifth in the

Opening position to move. In other words, it is one

current-operated normal operation of the door handle assembly 3 is no longer possible. According to the invention, however, the door handle assembly 3 is designed such that it can enable an electroless emergency operation even without electrical supply, by the alone with manual operation by a user, the lock 5 of a door 1 of a vehicle 1 can be opened. In the

Figures 15 to 23, the currentless emergency operation of the door handle assembly 3 is explained below.

FIGS. 15, 16 and 17 again show the basic position of the door handle arrangement 3, in which the handle 4 in the

Rest position, the transmission element 15 in the home position, the opening lever 28 are arranged in the neutral position and the locking means 23 in the latching position. As already explained above for the normal mode of operation,

prevents the locking means 23 a movement of the

Transmission member 15 in a direction opposite to the direction of the gear 27. The blockage creates that

Locking means 23, by abutting a stop surface 48 (see Figure 16) of the handle support 6. In this way it is prevented that the transmission element 15 can move with the attached locking means 23 away from the gear 27. A movement in the direction of the gear 27 is possible, however, because of

Handle carrier 6 has a movement recess 49, which allows the locking means 23 in its locking position, that the transmission element 25 in the current-driven normal operation

together with the latching means 23 from the home position on the first normal operating position in the second

Normal operating position can move.

In currentless emergency mode, a user is now manually the

Handle 4 in a first step in the direction of

Press vehicle interior, which is shown in Figures 18 and 19 with reference to the respective arrow. In other words, that is

Handle 4 in the powerless emergency operation from the straight-line rest position in one in the door 2 engaged

Unlocking position movable. The two figures 18 and 19 show different lateral sectional views of

Handle carrier 6 with the stored and attached thereto

Components. The force directed inwardly on the handle 4 by the user causes the lever member 9 to pivot about the pivotal axis 21 via the engaged handle 4, whereby the force acting on the first longitudinal end 11 and the pivot axis 21 of the Lever element 9 extending beyond Entriegelungsansatz 20 moves in the direction of the handle support 6. Because that is

Transmission member 15 is in the home position, in which the Entriegelungsansatz 20 between the first and second

Ausschwenkfläche 18, 19 is arranged, presses the

Unlocking approach 20 against the locking means 23 and rotates this about its axis of rotation 50 (see, for example, Figures 17 and 18) that the locking means 23 is moved out of its locking position and out of engagement with the handle support 6, as shown in Figure 18 ,

The fact that the locking means 23 is no longer at the

Stop surface 48 of the handle support 6 is present, a movement of the transmission element 15 is opposite to the direction rotatably mounted on the handle support 6 gear 26 possible. The spring element 36 pulls the transmission element 15 away from the gear 26 and moves the transmission element 15 into an emergency operating position (see FIGS. 20 and 21) when the latching means 23 is moved out of its latching position. In other words that's it

Transmission element 15 biased in the direction of the emergency operating position, wherein a locking means 23 pivotally mounted on the

Transmission element 15 is mounted, which in his

Locking position blocks a movement of the transmission element 15 from the basic position in the direction of the emergency operating position.

As can be seen from Figure 20, the moves

Entriegelungsansatz 20 during the movement of the transmission element 15 from the basic position to the emergency operating position along the second Ausschwenkfläche 19, which pivoting of the

Lever element 9 causes about the pivot axis 21, which in turn causes that at the second longitudinal end 14 of the

Lever element 9 mounted handle 4 is issued in the operating position in which it protrudes from the door 2 of the vehicle 1. In this movement of the transmission element 15, the movement pin 25 of the rack 26 moves in the recess 24 of the transmission element 15 relative to this, without causing the opening lever 28 is moved out of its neutral position. Consequently, the transfer element 15 moves in its movement from the home position in the direction of Emergency operating position the Entriegelungsansatz 20 along the second Ausschwenkfläche 19 such that the lever member 9 pivots about the pivot axis 21 and the handle 4 in the

Actuator position moves. The manually performed by a user impressions of the handle 4 thus causes the handle 4 is issued automatically and without current-driven drive 38 in the operating position.

Both for the current-driven normal operation and for the currentless emergency operation applies that the first Ausschwenkfläche 18 and the second Ausschwenkfläche 19 are each formed as an obliquely away from the handle support 6 leading surface, which upon movement of the transmission element 15 in the first normal operating position or in the Emergency operating position the

Entriegelungsansatz 20 pushes away from the handle support 6 and thereby pivots the handle 4 in the operating position in which a user can operate or handle them to open the lock 5. Likewise applies to normal operation and emergency operation that the movement of the transmission element 15 from the

Basic position at least in the emergency operating position is a linear movement, which is at least in the first to the movement of the transmission element 15 from the home position

Normal operating position in an opposite direction

runs.

So that the lock 5 of the door 2 of the vehicle 1 now in

de-energized emergency operation can be opened, the user must first unlock the lock 5 of the door 2 with the aid of a mechanical emergency key. As for example from FIG. 3

can be seen, leaves in the operating position

arranged handle 4 it is that such a mechanical emergency key can be inserted into the emergency lock cylinder 8 to unlock the lock 5.

When the lock 5 is unlocked with the aid of the emergency key, the lock 5 can be opened by the user pulling on the handle 4 or by pivoting the handle 4 about the axis of rotation 41. In contrast to the current-driven normal operation is in the currentless emergency operation, a pivoting in the

Operating position arranged handle 4 of about 30 ° necessary to achieve the desired opening of the lock 5. By pulling on the handle 4, as shown in Figures 22 and 23, the handle 4 rotates about the

Rotation axis 41, whereby a formed on the handle 4 approach 51 moves in the direction of the gear 27. This approach 51 presses on the guided in the guide channel 32 in the direction of the gear 27 handling member 31, so that the

Handling element 31 moves in the direction of the gear 27 and held on the rotationally fixed to the gear 27

Opening lever 28 presses. As a result, the opening lever 28 is moved from the neutral position to that shown in FIG

Turned opening position, so that with the lock 5

coupled Bowden cable 30 is actuated and the lock 5 is opened. Accordingly, the handle 4 on the

Handling element 31 with the opening lever 28 such

operatively coupled or connected, that in the currentless emergency operation by an operation of the in their

Operating position arranged handle 4, the handle 4, the handling element 31 against the opening lever 28 urges and moves it from the neutral position to the open position.

In summary, a door handle assembly 3 has been described above, in which in a power-driven

Normal operation, the handle 4 is issued from its strbbündigen position, whereby a user can operate the handle 4, which is detected by sensors or switches, after which the lock 5 of the door is opened electrically. The

Door handle assembly 3 is characterized by its mechanical

Redundancy, which allows an electroless emergency operation, wherein the transmission element 15, the opening lever 28 and the

Handle 4 functions are assigned to open the lock 5 of the door 2 both in normal operation and in the current-operated emergency operation.
