Description

The invention is directed to a door handle arrangement of a motor vehicle, comprising a carrier which can be fastened to a door or flap of the motor vehicle, a handle body which is pivotably mounted on the carrier about an axis of rotation and which can be moved manually from a rest position via an intermediate position into an end position, and a force increasing device which, when the handle body moves from the rest position until the intermediate position is reached, is designed to generate a resistance force that counteracts the movement of the handle body.

A door handle assembly of the type mentioned is, for example, from EP 1 819 892 B1 known. In this known door handle arrangement, a resistance device is effective at the end of a first actuation path of a manually operated handle body, which increases the actuation resistance for a short time, so that a switch for electrically opening the door lock is only actuated after or when a noticeable pressure point has been overcome and the door lock opens electrically. If the handle is deflected beyond the first actuation path along a second actuation path, the door lock is opened mechanically in an emergency, such as in the case of an empty vehicle battery, whereby an actuation force is required that is greater than the force required for electrical opening is necessary. It is due to the design of the door handle assembly that the EP 1 819 892 B1 an increased operating force of the handle body is already required for normal operation of the door handle assembly in order to reach or overcome the pressure point and to open the door lock electrically, which disadvantageously restricts the comfort of the door handle assembly.

The invention is based on the object of creating a solution that provides an improved door handle arrangement in a structurally simple manner, by means of which the aforementioned disadvantages are avoided and by means of which handling is possible for the operator.

In a door handle arrangement of a motor vehicle of the type described at the outset, the object is achieved according to the invention in that the force increasing device has an elastically deformable force increasing element which generates the resistance force and which is fastened to the handle body, a resistance element which interacts with the force increasing element and which is both linearly movable and rotatable the handle body is mounted, and a movement element cooperating with the resistance element, which moves the resistance element translationally in relation to the axis of rotation of the handle body in relation to the axis of rotation of the handle body when the handle body is moved from the rest position until the intermediate position is reached against the resistance force generated by the force increasing element in the direction of the force increasing element when the handle body is moved from the end position into the rest position so as to be rotationally movable with respect to an axis of rotation. The axis of rotation is fixed on the handle body or the resistance element rotates about the axis of rotation arranged on the handle body. In the context of the invention, a translational movement is understood to mean a movement in which the resistance element moves linearly to the axis of rotation of the handle body, so that the resistance element is displaced linearly to the axis of rotation. Furthermore, in the context of the invention, a rotational movement is to be understood as a movement in which the resistance element is rotated about the axis of rotation.

Advantageous and expedient configurations and developments of the invention emerge from the subclaims.

The invention provides a door handle arrangement which is characterized by a simple construction. In the case of the door handle arrangement according to the invention, a door lock of the door of the motor vehicle can be opened electrically before or when the intermediate position of the handle body is reached, so that the operator does not have to exert an increased amount of force as in the prior art. The door lock can consequently be opened electrically with the application of a minimal expenditure of force. According to the invention, the force increasing element generating the resistance force is only effective when the handle body is moved from the rest position into the intermediate position. In this way, the operator of the door handle arrangement receives a noticeable feedback for him, with the operator not having to reach the intermediate position at all in order for the door lock to be opened electrically. The intermediate position only needs to be reached and overcome by the operator if a currentless emergency actuation is required, whereby the door lock can be opened purely mechanically with the aid of an actuation of the handle body, which is coupled to the door lock via a Bowden cable, for example. Since the force increasing element is only effective when the handle body moves from the rest position into the intermediate position, the operator of the door handle arrangement does not have to use an operating force increased by the force increasing device for mechanical emergency opening of the door lock, which facilitates the operation of the door handle arrangement according to the invention in an emergency operation. According to the invention, therefore, when the handle body is actuated from the rest position in the direction of the end position, an actuating force is to be applied, by means of which the resistance element is moved in a translatory manner in the direction of the force increasing element. This increase in force is only present until the intermediate position is reached. As soon as the intermediate position is exceeded and the grip body continues in Is moved towards its end position, no increase in force is noticeable for the operator. The resistance element is arranged in the movement path of the movement element both when the handle body moves from the rest position into the end position and when the handle body moves from the end position into the rest position, so that the movement element strives according to the invention to force the resistance element out of its path of movement . The handle body is usually biased into its rest position by means of a spring element, so that after the action of an actuating force by the operator, the handle body tries to return to its rest position. For a movement of the handle body from the end position into the rest position, this spring element can be dimensioned small, because when the handle body is moved back into the rest position, the resistance element on the handle body is not moved in a translatory manner, as in the movement towards the end position, but in a rotational manner, including a much less force is required.

In an embodiment of the door handle arrangement according to the invention, it is provided that the movement element is designed as a movement attachment protruding from a base body mounted on the carrier. The movement attachment can be designed in the manner of a lever arm which interacts with the resistance element when the handle body moves.

In a further embodiment of the door handle arrangement, the invention provides that the movement element is pivotably mounted on the carrier via a pivot axis, the handle body and the movement element being coupled to one another for movement in opposite directions about the axis of rotation and the pivot axis when the handle body moves. In this case, the movement element is designed as a mass balancing element which, in the event of a vehicle accident, ensures that the grip body is effective due to the effects of the accident Acceleration forces do not get into a position in which the door lock can be opened.

In a further embodiment of the invention, the handle body has at least one pivot lever connected to the axis of rotation on which a coupling recess is formed is formed, which is arranged in the coupling recess of the at least one pivot lever of the handle body.

A structurally advantageous possibility for the interaction of the resistance element with the force increasing element is that the resistance element has a functional body with a support surface, the functional body being inserted at least in sections into a receiving frame formed on the handle body and the force increasing element between the support surface of the functional body and a the handle body formed mounting surface is arranged.

For the arrangement of the resistance element on the handle body, the invention in an embodiment of the door handle arrangement provides that the functional body of the resistance element has at least one support element protruding laterally from the functional body, with the at least one support element resting on the receiving frame and the force increasing element in the rest position of the handle body the support element presses on the receiving frame. This position of the resistance element when the force increasing element presses the at least one support element onto the receiving frame can be regarded as a basic position of the resistance element.

In a further embodiment of the door handle arrangement according to the invention it is provided that the handle body has at least one first guide surface and at least one second guide surface which is designed to run parallel to the at least one first guide surface, a ramp surface being formed on the functional body, which is formed on the side of the functional body facing away from the support surface and which is in a the wearer pointing direction increases. The functional body is arranged between the at least one first guide surface and the at least one second guide surface. The guide surfaces serve that the functional body of the resistance element can be moved linearly along and between the guide surfaces.

In a further embodiment of the invention, it is particularly advantageous if, when the handle body moves from the rest position into the intermediate position, the movement element rests on the ramp surface and the functional body of the resistance element against the resistance force of the force increasing element is linear in the direction of the force increasing element with respect to the axis of rotation of the handle body is designed to move along the at least one first guide surface and the at least one second guide surface.

The movement of the functional body of the resistance element is brought about by the movement element, the invention providing in a further embodiment in this regard that the movement element rests against and moves linearly with respect to the axis of rotation of the handle body along the ramp surface when the handle body moves from the rest position into the intermediate position is formed, wherein the movement element is arranged spaced apart from the ramp surface when the handle body moves beyond the intermediate position up to the end position and the at least one support element is arranged resting on the receiving frame. The movement element thus comes into the intermediate position when the handle body moves from the rest position Rest on the ramp surface and presses the resistance element in the direction of the force increasing element, the force increasing element generating the resistance force when the resistance element moves.

For a rotational movement of the resistance element, a further embodiment of the door handle arrangement according to the invention provides that two pivot pins are formed on two opposite sides of the functional body of the resistance element, which at least in the rest position of the handle body in corresponding bearing receptacles which are formed in the receiving frame of the handle body, are arranged rotatably mounted, wherein the pivot pin form the axis of rotation.

With regard to the rotational movement of the resistance element, the invention provides that when the handle body moves from a position between the intermediate position and the end position into the rest position, the movement element comes into contact with the functional body and the functional body arranged with its two pivot pins in the corresponding bearing receptacles against the direction of rotation of the handle body in the bearing receptacles is designed to move rotationally with respect to the axis of rotation.

Finally, for guiding the rotational movement, it is advantageous if the functional body has two guide arms which are formed on opposite sides and are angled and the handle body has two guide recesses extending in an actuation direction of the handle body and the end position in the rest position the two guide arms are arranged lying and guided in the guide recesses of the handle body.

In Figure 1 a vehicle or motor vehicle 1 in the form of a car is shown as an example, which in the example has four doors 2 (two of which are from Figure 1 can be seen), which has a door handle arrangement 3 and in particular with the aid of a handle part 4a attached to a handle body 4 (see for example Figure 2b ) can be opened. With reference to the Figures 1 to 3 the doors 2 are locked via respective door locks 5 and can be opened from the outside via a respective actuation of the handle body 4 or handle part 4a. The handle body 4 has the handle part 4a which can be reached from behind and which can be actuated to open the door lock 5, the actuation in the exemplary embodiment shown in the figures being a pulling force exerted by an operator on the handle body 4 or on the handle part 4a. To open the door 2, the handle body 4 is then pivoted to a certain degree during normal operation, whereby a switch is actuated, which in turn controls an electromechanical locking system 6 (see FIG Figure 3 ) activated, with the help of which the door lock 5 can then be opened electrically. When the handle body 4 is pivoted to a certain extent in order to open the door lock 5 electrically, the handle body 4 is moved from a rest position in the direction of an end position. The electrical opening can take place before an intermediate position is reached, in the intermediate position or after the intermediate position has been exceeded but before the end position is reached.

From the Figure 2a it can be seen that the handle part 4a of the handle body 4 is on the outside of the door 2 of the motor vehicle 1 is arranged, wherein the handle part 4a can be grasped from behind by an operator. the Figure 2a shows a position in which the handle body 4 is arranged in the rest position. To couple the handle body 4 to the door 2, a frame-like support 7 is provided, which is only in Figures 2b and 3 is shown schematically and dashed, since it is on the inside of the door 2 and thus in the Figures 1 to 3 is arranged covered by the door 2. The carrier 7 is fastened on the inside of the door 2 by known fastening means and supports the handle body 4 with its handle part 4a arranged on the outside of the door 2. In other words, the carrier 7 is known to be used to attach and support the handle body 4 and is fastened to the inside of the door 2 by means of screw connections not shown in detail. In order to save material, the carrier 7 is mainly formed from a frame structure which has various receiving and storage spaces in order to, in addition to the handle body 4, which is mounted on the carrier 7 for opening a corresponding door 2 of the motor vehicle 1, for example a lock cylinder to be able to record. In Figure 2b the handle part 4a is pivoted beyond the intermediate position into an end position. In the end position, door 2 can be opened mechanically, which is achieved by means of a Bowden cable system 8 (see for example Figures 1 and 3 ) is achieved, which mechanically operatively connects the door lock 5 and the handle body 4 with one another. Mechanical opening is only necessary in a currentless emergency operation, because in normal operation the door lock 5 is electrically opened at the latest before reaching the intermediate position or when reaching the intermediate position or shortly after the intermediate position is exceeded and before the end position of the handle body 4 is reached .

In Figure 4 the door handle assembly 3 according to the invention is shown in a perspective view, for reasons of For clarity, a representation of the carrier 7 and the handle part 4a has been omitted. The handle body 4 has two pivot levers 9 which are arranged at a distance from one another and to which the handle part 4a is releasably attached. The two pivot levers 9 of the handle body 4 are angled and L-shaped. The handle body 4 with its two pivot levers 9 is mounted pivotably about a rotation axis 10 on the carrier 7, so that an operator can pivot the handle body 4 about the rotation axis 10 by a manual pulling movement on the handle part 4a and the handle body 4 from a rest position via a Can move intermediate position to an end position. A mass balancing element 11 is also rotatably mounted on the carrier 7, which at least contributes to or prevents the handle body 4 from being deflected as a result of acceleration forces acting on the motor vehicle 1 in the event of an accident and from opening the door lock 5 undesirably. The mass balancing element 11 is supported by a pivot axis 12, which is supported by laterally protruding pins 14 (in Figure 4 only one of the two pins 14 can be seen) and which runs parallel to the axis of rotation 10, is rotatably mounted on the carrier 7, the mass balancing element 11 having a balancing mass 15 which is arranged between the two pivot levers 9 of the handle body 4.

In Figure 5 the door handle assembly 3 is off Figure 4 shown in a rear view, whereas the Figure 6 shows a perspective detail view of the door handle arrangement 3. It should be noted that for the door handle arrangement 3 according to the invention in FIGS Figures 5 to 38 For the sake of clarity, the carrier 7 and the handle part 4a are not shown. Like that Figures 5 and 6 As can be seen, the door handle arrangement 3 has a force increasing element 16 fastened to the handle body 4 and a resistance element 17 which interacts with the force increasing element 16 and is movably supported on the handle body 4. With the resistance element 17, a movement element 18 interacts, which in the illustrated embodiment is the mass balancing element 11, so that the movement element 18 is pivotably mounted on the carrier 7 via the pivot axis 12. Alternatively, the movement element 18 could also be formed on the carrier 7. For the interaction of the movement element 18 with the resistance element 17, the movement element 18 has a movement attachment 19 which protrudes from the compensation mass 15 in the direction of the movement element 18, the compensation mass 15 at the same time representing a base body 20 for the movement element 18. The force increasing element 16, the resistance element 17 and the movement element 18 together form a force increasing device 21, which is designed such that when the handle body 4 moves from the rest position until the intermediate position is reached, a resistance force counteracting the movement of the handle body 4 is generated, whereas When the handle body 4 moves beyond the intermediate position in the direction of the end position and when the handle body 4 moves from a position between the end position and the intermediate position towards the rest position, the force increasing element 16 does not generate any resistance force.

In the Figures 7 to 9 details are shown which relate to a coupling of handle body 4 and movement element 18. This is because the movement element 18 is coupled in terms of movement to the handle body 4 in such a way that the handle body 4 and the movement element 18 rotate in opposite directions when the handle body 4 moves. If the handle body 4 is pivoted counterclockwise about the axis of rotation 10, for example by an operator actuation, the movement element 18 rotates clockwise about the pivot axis 12 as a result of the movement coupling. The handle body 4 and the movement element 18 are consequently when the handle body moves 4 rotating in opposite directions about the axis of rotation 10 and the pivot axis 12 motion-coupled to one another. For this purpose, a coupling recess 22 is provided on each of the two pivot levers 9 of the handle body 4 (see for example Figure 7 ), with a single coupling recess alternatively also being sufficient to couple the handle body 4 to the movement element 18. Two laterally projecting coupling lugs 23 are formed on the movement element 18 and extend parallel to the pivot axis 12 (see, for example, FIG Figure 6 ), with a respective coupling extension 23 protruding from a respective coupling arm 24, which extends from the pivot axis 12 of the movement element 18, so that a respective coupling extension 23 is arranged at a distance from the pivot axis 12. The coupling lugs 23 are correspondingly arranged within the coupling recess 22 assigned to them. the Figure 8 shows an enlarged detailed view and the Figure 9 a lateral sectional view, the two figures showing how the coupling lugs 23 are arranged within the coupling recesses 22. According to the alternative embodiment, a coupling approach with a coupling recess would also be sufficient to implement the movement coupling between the handle body 4 and the movement element 18.

In the Figure 10 an enlarged detailed view of the grip body 4, force increasing element 16 and resistance element 17 is shown, whereas Figure 11 shows a perspective view of the force increasing element 16. The force increasing element 16 is elastically deformable and angled and has a fastening surface 25 which is fastened to a mounting surface 26 formed on the handle body 4, for example via a screw connection. From the fastening surface 25 of the force increasing element 16, an angled spring arm 27 extends in the direction of the resistance element 17 and has a rounded portion 28 at the end (see FIG Figure 11 ). The rounding 28 of the force increasing element 16 is at least in the rest position of the handle body 4 on a support surface 29 formed on the resistance element 17, as is the case, for example Figure 10 shows. The force increasing element 16 is consequently arranged between the bearing surface 29 of the resistance element 17 and the mounting surface 26 formed on the grip body 4, the bearing surface 29 being formed on a functional body 30 of the resistance element 17 that serves several functions.

The ones described below Figures 12 to 26 show structural details by means of which the functional body 30 of the resistance element 17 is mounted on the handle body 4 such that it can move translationally and rotationally, wherein for the sake of clarity in FIGS Figures 12 and 13 the force increasing element 16 was not shown. At least in the rest position of the handle body 4, ie in the inactivated state of the door handle arrangement 3, the functional body 30 of the resistance element 17 is inserted at least in sections into a receiving frame 31 which is adapted to the outer circumference of the functional body 30 and which is formed on the handle body 4 (see for example Figures 12 and 13 ). On opposite side surfaces of the functional body 30 of the resistance element 17 there is a support element 32 (see for example Figure 21 ). The support elements 32 of the functional body 30 extend laterally from the functional body 30 and parallel to the axis of rotation 10, with the peg-shaped support elements 32 resting on the receiving frame 31 of the handle body 4 at least in the rest position of the handle body 4. When the support elements 32 of the functional body 30 are arranged resting on the receiving frame 31 of the handle body 4, the resistance element 17 is arranged in a basic position on the handle body 4. In the rest position of the handle body 4, the force increasing element 16 presses the support elements 32 of the functional body 30 onto the receiving frame 31, as is the case for Example in Figure 10 is shown. The support elements 32 are, for example, made of Figure 21 can be seen, and this illustration also shows pivot pins 33 which are formed on opposite sides of the functional body 30 and which are designed to lie between a respective support element 32 and the functional body 30. Bearing receptacles 34 are formed in the handle body 4 to correspond to the pivot pins 33. More precisely, the bearing receptacles 34 are formed in the receiving frame 31 of the handle body 4 and, at least in the rest position of the handle body 4, support the pivot pins 33 of the resistance element 17 in a rotatable manner. At least in the rest position of the handle body 4, the force increasing element 16 presses the pivot pins 33 into the associated bearing receptacles 34, which is also indicative of the fact that the resistance element 17 is arranged in its basic position. Like the Figure 21 As can be seen, the functional body 30 has two guide arms 35 which are integrally formed and angled on opposite sides of the functional body 30. The guide arms 35 of the resistance element 17 encompass the receiving frame 31 of the handle body 4, the sections of the guide arms 35 running parallel to the axis of rotation 10 having a respective support element 32 and a respective pivot 33. In addition, a first guide surface 36 and second guide surfaces 37 are formed on the grip body 4, the second guide surfaces 37 being arranged offset parallel to the first guide surface 36. The first guide surface 36 and the second guide surfaces 37 run in the direction of the force-increasing element 16 or in the direction of the mounting surface 26, the first guide surface 36 as the inside of the receiving frame 31 (see, for example, FIG Figures 27 and 29 ) is formed, whereas the second guide surfaces 37 are arranged and formed centrally on the handle body 4 between the two pivot levers 9 of the handle body 4. The first guide surface 36 and the second Guide surfaces 37 are arranged at a distance from one another in such a way that the resistance element 17 can be moved between the first guide surface 36 and the second guide surfaces 37. Finally, a ramp surface 38 is formed on the functional body 30 of the resistance element 17, which is formed on the side of the functional body 30 facing away from the support surface 29 and which rises in a direction pointing to the carrier 7, as is shown, for example, in FIG Figure 22 is shown. While in the Figures 12 and 13 the support elements 32 of the functional body 30 are arranged on the receiving frame 31 and the pivot pins 33 are arranged in the bearing receptacles 34 of the handle body 4, FIGS Figures 14 to 16 a position of the functional body 30, in which the functional body 30 linearly from the in the Figures 12 and 13 The position shown has been moved and is arranged in a translation position in which the support elements 32 and the pivot pins 33 are arranged at a distance from the receiving frame 31. The functional body 30 is consequently arranged in its translational position moved in translation with respect to the axis of rotation 10 of the handle body 4 relative to the handle body 4, the translational movement of the resistance element 17 being guided by the first guide surface 36 and the second guide surfaces 37 by the first guide surface 36 and the second guide surfaces 37 guide associated side surfaces of the functional body 30, and against a resistance force 39 generated by the force increasing element 16 (see for example Figure 16 ) he follows. Also show the Figures 17 to 20 Representations in which the resistance element 17 is rotated from a position in which the support elements 32 of the functional body 30 rest on the support frame 31. The rotational movement of the resistance element 17 takes place in the bearing receptacles 34 of the handle body 4 around the pivot pin 33, so that the pivot pin 33 has a rotation axis 40 (see for example Figure 20 ) for the Define resistance element 17. How out Figures 17 and 18 As can be seen, there are two guide recesses 41 in the handle body 4 (see for example Figures 17 and 18 ) formed, in which the free ends of the guide arms 35 can move into when the resistance element 17 is rotated and in which the free ends of the guide arms 35 are arranged when the functional body 30 is in the Figures 17 to 20 Assumes rotational position. When the resistance element 17 rotates, the guide recesses 41 consequently guide the movement of the free ends of the guide arms 35. The guide recesses 41 extend in an actuation direction 42 of the handle body 4, the actuation direction 42 (see for example Figure 29 ) is defined as the direction in which the handle body 4 or its pivot lever 9 moves or move when moving out of the rest position in the direction of the end position.

Responsible for the translational and rotational movement of the resistance element 17 is the movement element 18 with its movement attachment 19, which interacts with the functional body 30 of the resistance element 17, which will be described in more detail below. The functional body 30 of the resistance element 17 is in the movement path of the movement attachment 19 of the movement element 18 when the handle body 4 moves out of the rest position in the direction of the end position and when the handle body 4 moves from a position between the intermediate position and the end position in the direction of the rest position arranged so that the movement element 18 endeavors to force the functional body 30 of the resistance element 17 out of the path of movement. the Figures 23 and 24 show again the structural details of the movement element 18, namely the pivot axis 12, the movement attachment 19 and the coupling attachments 23 for the movement coupling with the handle body 4. In the Figures 25 and 26 are also shown two positions that the interaction of movement element 18 and Show resistance element 17. The Figure 25 a position in which the grip body 4 was moved from the rest position in the direction of the intermediate position, so that the movement attachment 19 of the movement element 18 comes into contact with the ramp surface 38 of the resistance element 17 and the resistance element 17 pushes linearly or translationally in the direction of the force increasing element 16 . The movement element 18 consequently urges the resistance element 17 from its basic position into its translation position when the grip body 4 moves from its rest position into its intermediate position. the Figure 26 shows, however, a position in which the grip body 4 is moved from the end position towards the rest position, whereby the movement attachment 19 of the movement element 18 comes into contact with the functional body 30 and the functional body 30 rotates or rotates about the axis of rotation 40. Consequently, the movement element 18 urges the resistance element 17 from its basic position into its rotational position when the grip body 4 moves from a position between the end position and the intermediate position in the direction of its rest position.

With reference to the Figures 27 to 39 the mode of operation of the door handle arrangement 3 according to the invention will now be described below. They show Figures 27, 29, 31 , 33, 35 and 37 in each case a sectional view in which the section runs centrally through the door handle arrangement 3. On the other hand, they show Figures 28, 30, 32 , 34, 36 and 38 in each case a sectional view in which the section runs just in front of one of the two guide arms 35.

In the Figures 27 and 28 the handle body 4 is in its rest position, in which the handle body 4 is not actuated, and the resistance element 17 is arranged in the basic position in which the support elements 32 of the functional body 30 rest on the receiving frame 31 of the handle body 4 and the Trunnions 33 of the functional body 30 are arranged in stock in the bearing receptacles 34 of the handle body 4.

In order to initiate a door opening process, the handle body 4 is actuated by an operator by pulling on the handle part 4a. With this pulling operation, the grip body 4 is turned around the axis of rotation 10 in an anti-clockwise direction (see arrow 43 in Figure 29 ) is pivoted, with the movement element 18 being pivoted clockwise (see arrow 44 in FIG Figure 29 ), that is, in the opposite direction to the handle body 4, rotates about the pivot axis 12. During this movement of the handle body 4 from the rest position in the direction of the intermediate position, the movement attachment 19 of the movement element 18 comes into contact with the ramp surface 38 of the functional body 30, as shown in FIG Figure 29 can be seen. The resistance element 17 is still arranged in its basic position.

If the operator then continues to pull on the handle part 4a of the handle body 4, the handle body 4 is pivoted further about the axis of rotation 10 in the counterclockwise direction, whereby the movement element 18 continues to pivot about the pivot axis 12 in the clockwise direction due to the movement coupling. In the Figures 31 and 32 the handle body 4 has reached its intermediate position, in which an electrical opening of the door 2 takes place during normal operation of the door handle assembly 3 by triggering a button or sensor in this position in a known manner, which sends a signal to the locking system 6 for electrical Opening of door 2 sends. The pulling actuation of the handle body 4 by an operator in the actuating direction 42 takes place against the resistance force 39, which is exerted on the resistance element 17 by the force increasing element 16. Because when the handle body 4 moves in the direction of in Figure 31 The intermediate position shown, the movement attachment 19 of the movement element 18 presses the resistance element 17 in the direction of the force increasing element 16 and moves the resistance element 17 translationally along the first guide surface 36 and the second guide surfaces 37. As a result of the translational movement of the resistance element 17, the resistance element 17 compresses the force increasing element 16, which generates the resistance force 39, which acts in the opposite direction of the translational movement. Due to the force to be applied for the translational movement of the resistance element 17, an increase in force for pivoting the handle body 4 can be felt by the operator of the door handle arrangement 3. Before reaching the in the Figures 31 and 32 The intermediate position shown is in normal operation of the door handle assembly 3 - as already mentioned above - the door 2 is opened electrically, so that an operator moves the handle body 4 at most unintentionally or with too much force into the intermediate position or beyond the intermediate position. In the intermediate position of the handle body 4, the movement attachment 19 of the movement element 18 has reached a maximum of the ramp surface 38.

the Figures 29 to 32 In summary, it should be noted that when the handle body 4 moves from the rest position into the intermediate position, the movement element 18 rests against the ramp surface 38 and the functional body 30 of the resistance element 17 against the resistance force 39 of the force increasing element 16 linearly or translationally in relation to the force increasing element 16 is designed to move on the axis of rotation 10 of the handle body 4 along the first guide surface 36 and the second guide surfaces 37. When the handle body 4 moves from the rest position into the intermediate position, the movement element 18 is consequently designed in such a way that its movement attachment 19 moves along the ramp surface 38 and the resistance element 17 moves linearly or translationally in relation to the axis of rotation 10 of the handle body 4 in the direction of the force increasing element 16 is moved so that the resistance element 17 compresses the force increasing element 16. In the in the Figures 31 and 32 The intermediate position shown of the handle body 4, the resistance element 17 assumes a translation position. In the translational position of the resistance element 17, the pivot pins 33 of the functional body 30 are arranged at a distance from the bearing receptacles 34 and the support elements 32 of the functional body 30 are arranged at a distance from the receiving frame 31, the functional body 30 being displaced translationally within the receiving frame 31 relative to its basic position is arranged, as it is already in the Figures 14 and 16 is shown.

The door can therefore be opened electrically when the movement attachment 19 of the movement element 18 moves along the ramp surface 38 or, alternatively, after the intermediate position has been exceeded, with the operator of the door handle arrangement 3 experiencing a noticeably increasing resistance from the force increasing element 16 when the functional body 30 is moved in a translatory manner perceives, whereas when the intermediate position is exceeded, the force to be exerted by the operator to pivot the handle body 4 decreases noticeably and the exceeding may be accompanied by an acoustic noise, which signals to the operator that he has reached or reached the actuation point for electrically opening the door 2. has exceeded.

In the Figures 33 and 34 the handle body 4 is now maximally actuated by an operator and arranged in its end position. In this case, the resistance element 17 is now arranged again in its basic position after passing through the intermediate position of the handle body 4. After the movement attachment 19 of the movement element 18 has passed the ramp surface 38 of the functional body 30, the force increasing element 16 pushes the resistance element 17 out of the translation position due to its elasticity (see FIG Figures 31 and 32 ) back to its home position (see Figures 33 and 34 ), so that the support elements 32 are now back on rest on the receiving frame 31 of the handle body 4 and the pivot pins 33 of the functional body 30 are again arranged in the bearing receptacles 34 of the handle body 4. The movement element 18 is arranged at a distance from the ramp surface 38 during the movement of the handle body 4 beyond the intermediate position up to the end position.

When the handle body 4 moves from the rest position into the end position, the movement attachment 19 of the movement element 18 moves past the functional body 30 of the resistance element 17 and moves the resistance element 17, which is arranged in the movement path of the movement element 18, at least temporarily in a translatory direction of the force increasing element 16, as shown in FIGS Figures 27 to 34 is shown.

When the handle body 4 moves out of the end position in the direction of the intermediate position, the movement attachment 19 of the movement element 18 moves towards the functional body 30 and comes into contact with the functional body 30, as it does the Figures 35 and 36 can be found. The movement attachment 19 of the movement element 18 rests against a side surface 45 of the functional body 30 adjoining the ramp surface 38. The functional body 30 now has the freedom of movement due to its mounting of the pivot pins 33 in the bearing receptacles 34 to rotate about the pivot pins 33, which define the axis of rotation 40, when the movement attachment 19 of the movement element 18 as a result of the movement of the handle body 4 back into its rest position acts on the functional body 30 and pushes against it. They show Figures 35 and 36 a position in which the functional body 30 is already arranged rotated about the axis of rotation 40 in the bearing receptacles 34 counterclockwise, the handle body 4 in this case in a clockwise direction 44 about the axis of rotation 10 and the movement element 18 coupled to the handle body 4 in the opposite direction Rotates clockwise 43 about pivot axis 12. As already for the Figures 17 to 20 has been described, when the handle body 4 is moved from the end position to the rest position, the two guide arms 35 are at least temporarily positioned and guided in the guide recesses 41 of the handle body 4, the movement element 18 coming into contact with the functional body 30 and the two with its two Trunnions 33 in the functional body 30 arranged in the corresponding bearing receptacles 34 are moved in the bearing receptacles 34 in a rotational manner about the axis of rotation 40 counter to the direction of rotation of the handle body 4. In the Figures 35 and 36 the resistance element 17 assumes a rotational position in which the resistance element 17 is arranged in the bearing receptacles 34 rotated about the axis of rotation 40 from the basic position.

When the handle body 4 moves from the end position back into the rest position, the movement attachment 19 of the movement element 18 moves past the functional body 30 of the resistance element 17 and rotates the resistance element 17, which is arranged in the movement path of the movement element 18, at least temporarily around the Axis of rotation 40 and from the path of movement of the movement element 18, the direction of rotation of the functional body 30 being directed against the direction of rotation of the handle body 4.

In summary, a door handle arrangement 3 according to the invention has been described above, which is characterized by the force increasing device 21 which, when the handle body 4 is actuated, noticeably increases the actuation resistance for an operator. The force increasing device 21 comprises the elastically deformable and the resistance force 39 generating force increasing element 16, which is attached to the handle body 4, the resistance element 17 cooperating with the force increasing element 16, which is both linearly movable and rotatably mounted on the handle body 4, and that with the Resistance element 17 cooperating movement element 18, which moves the resistance element 17 in a translatory manner in relation to the axis of rotation 10 of the handle body 4 when the handle body 4 moves from the rest position until the intermediate position is reached against the resistance force 39 generated by the force increase element 16 in the direction of the force increase element 16 and when the handle body 4 moves is designed such that it moves from the end position into the rest position in a rotational manner with respect to an axis of rotation 40.
