Description

Door handle assembly of a motor vehicle

The invention is directed to a door handle assembly of a motor vehicle, comprising a carrier attachable to a door or flap of the motor vehicle, one on the carrier

pivotally mounted about an axis of rotation and manually movable handle body, which from a rest position on a

Intermediate position is designed to be movable in an end position, and a force increasing device, which in a movement of the handle body from the rest position to reach the intermediate position, one of the movement of the handle body

counteracting resistance force is formed generating.

A door handle assembly of the type described is known for example from EP 1 819 892 Bl. In this known door handle assembly is at the end of a first

Actuation of a manually operated handle body, a resistance device effectively, which increases the operating resistance kurzeitig, so that a switch for electrically opening the door lock is operated only after or upon overcoming a noticeable pressure point and the door lock opens electrically. If the handle is deflected beyond the first actuation path along a second actuation path, then this becomes

Door lock in an emergency, such as in the case of an empty vehicle battery, mechanically open, which requires an actuating force that is greater than the force that is necessary for electrical opening. It is due to the construction of the door handle assembly of EP 1 819 892 Bl already for a normal operation of the door handle assembly an increased operating force of the handle body required to the

Pressure point to reach or overcome and to open the door lock electrically, which adversely restricts the comfort of the door handle assembly. The invention has for its object to provide a solution that provides a structurally simple way an improved door handle assembly, by which the above-mentioned disadvantages are avoided and by which a more comfortable for the operator handling is possible.

In a door handle assembly of a motor vehicle of

The type described above, the object is achieved in that the force increasing means an elastically deformable and the resistance generating

Force increasing element, which is fixed to the handle body, cooperating with the force increasing element

Resistance element, which is both linearly movable and rotatably mounted on the handle body, and a with the

Resistance element cooperating movement element, which moves the resistance element in a movement of the handle body from the rest position to reach the intermediate position against the force generated by the force increasing element in the direction of the force increasing element translationally with respect to the axis of rotation of the handle body and upon movement of the handle body from the end position in the rest position

rotationally moving with respect to a rotation axis

is formed. In this case, the axis of rotation is fixed to the handle body or the resistance element rotates about the arranged on the handle body rotation axis. For the purposes of the invention is under a translational movement a

Movement meant, in which the resistance element moves linearly to the axis of rotation of the handle body, so that the

Resistor element is moved 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 embodiments and

Further developments of the invention will become apparent from the

Subclaims. By the invention, a door handle assembly is provided, 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 already be opened electrically before or when the intermediate position of the grip body is reached, so that the operator does not have to apply an increased force as in the prior art. It can therefore be electrically opened by applying a minimum amount of force the door lock. According to the invention, the force-increasing element generating the resistance force is effective only when the grip body is moved from the rest position to the intermediate position. In this way receives the

Operator of the door handle assembly a palpable for him

Feedback, whereby the intermediate position by the operator does not have to be reached, so that the door lock is electrically opened. The intermediate position must be reached and overcome by the operator only if a de-energized

Emergency operation is required, whereby the door lock can be opened purely mechanically by means of an actuation of the handle body, which is coupled for example via a Bowden cable with the door lock. Since the force-elevating element only in a movement of the handle body from the rest position in the

Intermediate position is effective, the operator of the

Door handle assembly for mechanical emergency opening of the door lock no increased by the force increasing device

Apply operating force, which is the operation of the

Door handle assembly according to the invention in an emergency operation

facilitated. According to the invention is therefore at a

Actuating movement of the handle body from the rest position in the direction of the end position to apply an actuating force by which the resistance element is moved translationally in the direction of the force-elevating element. This power increase is only available until reaching the intermediate position. Once the intermediate position is exceeded and the handle body continues in Direction of its end position is moved, no more force increase is felt by the operator. The resistance element is both in a movement of the handle body from the rest position to the end position as well as a movement of the handle body from the end position to the rest position in the path of movement of

Movement element arranged so that the moving element according to the invention endeavors to urge the resistance element from its path of movement. The handle body is usually biased by a spring element in its rest position, so that after the action of an actuating force by the operator of the handle body endeavors to return to its rest position. For a movement of the handle body from the

End position in the rest position, this spring element can be dimensioned small, because in the return movement of the handle body in the rest position, the resistance element on the

Handle body does not move as in the direction of the

End position translational, but rotatory moves, what a much lower power 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 projection projecting from a base body mounted on the carrier. The movement approach may be of the type

Guide surfaces serve to ensure that the functional body of the resistance element linear along and between the

Guide surfaces can be moved.

Particularly favorable in a further embodiment of the invention, it is when in a movement of the handle body of the

Resting position in the intermediate position, the moving element rests against the ramp surface and the functional body of the

Resistance element against the resistance of the

Force elevation element in the direction of the force increasing element linear with respect to the axis of rotation of the handle body along the at least one first guide surface and the at least one second guide surface is designed to be moving.

The movement of the functional body of the resistance element is effected by the movement element, wherein the invention provides in a further embodiment in this respect that the

Movement element in a movement of the handle body from the rest position into the intermediate position adjacent to and linear with respect to the axis of rotation of the handle body along the

Ramp surface is designed to be moving, wherein the

Movement element at a movement of the handle body over the intermediate position addition to the end position spaced from the ramp surface is arranged and the at least one

1 shows a vehicle or motor vehicle 1 in the form of a car, which in the example has four doors 2 (two of which are visible in FIG. 1), which has a door handle arrangement 3 and in particular with the aid of a handle body 4 attached handle part 4a (see for example Figure 2b) can be opened. With reference to Figures 1 to 3, the doors 2 will be over respective ones

Locked door locks 5 and can be opened from the outside via a respective actuation of the handle body 4 and handle part 4a. The grip body 4 has the grasping grip part 4a, which can be actuated to open the door lock 5, wherein the actuation in the in FIGS

illustrated embodiment, a force exerted on the handle body 4 and on the handle part 4a pulling force of an operator. To open the door 2, the handle body 4 is then pivoted to a certain extent during normal operation, whereby a switch is actuated, which in turn activates an electromechanical locking system 6 (see Figure 3), with the help of the door lock 5 can then be opened electrically , In the

Pivoting of the handle body 4 to a certain degree to open the door lock 5 electrically, the handle body 4 is moved from a rest position toward an end position. In this case, the electric opening before the

Achieving an intermediate position, done in the intermediate position or after exceeding the intermediate position but before reaching the end position.

It can be seen from FIG. 2 a that the grip part 4 a of the grip body 4 is on the outside on the door 2 of the motor vehicle 1 is arranged, wherein the grip part 4a is engaged by an operator behind. FIG. 2a shows a position in which the grip body 4 is arranged in the rest position.

For coupling the handle body 4 to the door 2, a frame-like design support 7 is provided, which is shown schematically and dashed lines only in Figure 2b and 3, since he

inside of the door 2 and thus in Figures 1 to 3 hidden from the door 2 is arranged. The carrier 7 is fastened on the inside of the door 2 via known fastening means and supports the grip body 4 with its grip part 4a arranged on the outside of the door 2. In other words, the carrier 7 is known to the attachment and storage of the handle body 4 and is fastened by means not shown screw on the inside of the door 2. Here, the carrier 7 for reasons of material saving predominantly from a

Frame structure formed, which has various recording and storage rooms, in addition to the handle body 4, which on the

Carrier 7 for opening a corresponding door 2 of the

Motor vehicle 1 is stored, for example a

To be able to record lock cylinder. In Figure 2b is the

Handle part 4a beyond the intermediate position into a

End position pivoted. In the end position, a mechanical opening of the door 2 is possible, which is achieved by a Bowden cable system 8 (see, for example, Figures 1 and 3), which mechanically connects the door lock 5 and the handle body 4 together. A mechanical opening is only in one

currentless emergency operation necessary, because in normal operation, the door lock 5 at the latest before reaching the

Intermediate position or when reaching the intermediate position or shortly after exceeding the intermediate position and before reaching the end position of the handle body 4 electrically

open .

In Figure 4, the door handle assembly 3 according to the invention is shown in a perspective view, wherein for reasons of Clarity on a representation of the carrier 7 and the handle part 4a has been omitted. The grip body 4 has two pivoting levers 9, which are arranged at a distance from one another and to which the grip 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

Swing levers 9 is pivotable about an axis of rotation 10 on the

Carrier 7 stored so that an operator by a manual pulling movement on the handle part 4a, the handle body 4 to the

Rotate pivot axis 10 and can move the handle body 4 from a rest position via an intermediate position to an end position. On the carrier 7 is also a

Mass balance element 11 rotatably mounted, which at least contributes to or prevents the handle body 4 as a result of acting acceleration forces acting on the motor vehicle 1 in an accident, is deflected and the door lock 5 opens undesirable. The mass balance element 11 is a pivot axis 12 which is formed by laterally projecting pin 14 (in Figure 4 is only one of the two pins 14 to see) and which is parallel to the axis of rotation 10, rotatably mounted on the carrier 7, wherein the mass balance element 11 has a balancing mass 15, between the two

Swing levers 9 of the handle body 4 is arranged.

In Figure 5, the door handle assembly 3 of Figure 4 is shown in a rear view, whereas Figure 6 shows a perspective detail of the door handle assembly 3. It should be noted that for the door handle arrangement 3 according to the invention in FIGS. 5 to 38, a representation of the support 7 and the grip part 4a has been dispensed with for reasons of clarity. As can be seen in FIGS. 5 and 6, FIG

Door handle assembly 3 a attached to the handle body 4

Force increasing element 16 and cooperating with the force increasing element 16 resistance element 17 which is movably mounted on the handle body 4. With the resistance element 17 a movement element 18 cooperates, which in the illustrated embodiment, the mass balance element 11, so that the moving member 18 is pivotally mounted on the support 7 via the pivot axis 12. Alternatively, the moving 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 a

Movement approach 19, which at the balancing mass 15 in

Direction of the movement member 18 is formed protruding, wherein the balancing mass 15 simultaneously represents a base body 20 for the moving member 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 upon movement of the grip body 4 from the rest position until reaching the intermediate position of the movement of the handle body 4 counteracting resistance force is generated, whereas at a beyond the intermediate position extending movement of the handle body 4 in the direction of the end position and a movement of the handle body 4 from a position between the end position and the intermediate position in the direction of rest, the force increasing element 16 generates no resistance.

Details are shown in FIGS. 7 to 9, which relate to a coupling of the grip body 4 and the movement element 18

Respectively. For the movement element 18 is coupled to the handle body 4 in such a manner that the grip body 4 and the movement element 18 rotate in opposite directions during a movement of the grip body 4. If the grip body 4 is pivoted, for example, by an operator's operation about the rotation axis 10 in the counterclockwise direction, then the movement element 18 rotates clockwise as a result of the movement coupling in the clockwise direction

Pivot axis 12. The handle body 4 and the moving member 18 are consequently at a movement of the handle body 4 itself

rotating in opposite directions about the axis of rotation 10 and the pivot axis 12 motion coupled with each other. For this purpose, each of a pair of pivoting levers 9 of the handle body 4

Coupling recess 22 (see, for example, Figure 7) formed, where alternatively also a single coupling recess

would be sufficient to couple the handle body 4 with the moving member 18. Formed on the movement element 18 are two laterally projecting coupling lugs 23, which extend parallel to the pivot axis 12 (see for example FIG. 6), wherein a respective coupling lug 23 protrudes from a respective coupling arm 24 extending from the pivot axis 12 of the movement element 18 extends so that a respective one

Coupling approach 23 is arranged at a distance from the pivot axis 12. The coupling lugs 23 are correspondingly arranged within their respective associated coupling recess 22. FIG. 8 shows an enlarged detail view and FIG. 9 shows a lateral sectional view, it being apparent from the two figures how the coupling lugs 23 are arranged within the coupling recesses 22. According to the alternative embodiment, a coupling approach would also be sufficient in the case of a coupling recess in order to realize the movement coupling between the grip body 4 and the movement element 18.

FIG. 10 is an enlarged detail view of FIG

Handle body 4, force increasing element 16 and resistance element 17 are shown, whereas Figure 11 shows a perspective view of the force increasing element 16. The force increasing element 16 is formed elastically deformable and angled and has a mounting surface 25 which on one of the

Handle body 4 formed mounting surface 26 is fixed, for example via a screw connection. Extending in the direction of the resistance element 17 from the attachment surface 25 of the force-increasing element 16 is an angled spring arm 27, which has a rounded end 28 (see FIG. 11). The rounding 28 of the force increasing element 16 is at least in the rest position of the handle body 4 on a on the

Resistance element 17 formed support surface 29, as shown for example in FIG. The force increasing element 16 is thus arranged between the support surface 29 of the resistance element 17 and the mounting surface 26 formed on the handle body 4, wherein the support surface 29 at a plurality

Functions serving functional body 30 of the resistive element 17 is formed.

The figures 12 to 26 described below show structural details, by which the functional body 30 of the resistance element 17 is mounted on the handle body 4 movable in translation and rotationally movable, wherein for reasons of

Clarity in Figures 12 and 13 has been omitted from a representation of the force increasing element 16. At least in the rest position of the handle body 4, i. in the unactuated state of the door handle assembly 3, the functional body 30 of the

Resistance element 17 at least partially inserted into a adapted to the outer periphery of the functional body 30 Aufnähmerahmen 31 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 is in each case a support element 32 (see, for example, Figure 21). The support elements 32 of the functional body 30 extending laterally from the functional body 30 and parallel to the axis of rotation 10, wherein at least in the

Rest position of the handle body 4, the pin-shaped support elements 32 on the Aufnähmerahmen 31 of

Handle body 4 are arranged resting. If the

Support elements 32 of the functional body 30 on the

Aufnähmerahmen 31 of the handle body 4 are arranged resting, then 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 the Example is shown in Figure 10. The support elements 32 can be seen, for example, from FIG. 21, with pivots 33 being visible which are formed on opposite sides of the functional body 30 and which are formed lying between a respective support element 32 and the functional body 30. In the grip body 4 bearing receptacles 34 are formed corresponding to the pivot 33. More specifically, the bearing receivers 34 are formed in the receiving frame 31 of the grip body 4, and at least in the rest position of the grip body 4, the pivots 33 of the resistance member 17 are rotatably supported. At least in the

Rest position of the handle body 4 pushes the force increasing element

16, the pivot 33 in the associated bearing mounts 34, which is also characteristic that the resistance element

17 is arranged in its basic position. As can be seen, for example, from FIG. 21, the functional body 30 has two guide arms 35 formed on an opposite side of the functional body 30 and angled. The guide arms 35 of the resistance element 17 surround the

Aufnähmerahmen 31 of the handle body 4, wherein the parallel to the rotation axis 10 extending portions of the guide arms 35 have a respective support member 32 and a respective pivot 33. In addition, on the handle body 4, a first guide surface 36 and second guide surfaces 37th

formed, wherein the second guide surfaces 37 are arranged offset parallel to the first guide surface 36. The first guide surface 36 and the second guide surfaces 37 extend in the direction of the force-increasing element 16 or in the direction of the mounting surface 26, wherein the first guide surface 36 as an inner side of the Aufnähmerahmens 31 (see, for example

Figures 27 and 29) is formed, whereas the second

Guide surfaces 37 centrally disposed on the handle body 4 between the two pivot levers 9 of the handle body 4 and

are formed. The first guide surface 36 and the second Guide surfaces 37 are arranged spaced apart from one another such that the resistance element 17 is movable between the first guide surface 36 and the second guide surfaces 37. Finally, on the functional body 30 of the

Resistance element 17 a ramp surface 38 is formed, which is formed on the side facing away from the support surface 29 of the functional body 30 and which rises in a pointing towards the carrier 7 direction, as shown for example in Figure 22. While in Figures 12 and 13, the support members 32 of the functional body 30 on the receiving frame 31 and the

Trunnions 33 are arranged in the bearing receptacles 34 of the handle body 4, Figures 14 to 16 show a position of the functional body 30 in which the functional body 30 has been moved linearly from the position shown in Figures 12 and 13 and is arranged in a translational position, in which the support elements 32 and the pivot pins 33 are arranged at a distance from the Aufnähmerahmen 31. The functional body 30 is thus arranged translationally with respect to the axis of rotation 10 of the handle body 4 relative to the handle body 4 moves in its translational position, wherein the translational

Movement of the resistive element 17 from the first

Guide surface 36 and the second guide surfaces 37 is guided by the first guide surface 36 and the second

Guide surfaces 37 associated side surfaces of the

Function body 30 lead, and against one of the

Force increasing element 16 generated resistance force 39 (see, for example, Figure 16) takes place. Furthermore, FIGS. 17 to 20 show illustrations in which the resistance element 17 is moved out of a position in which the support elements 32 of FIG

Resting functional body 30 on the support frame 31, is rotationally moved. The rotational movement of the

Resistance element 17 takes place in the bearing receivers 34 of the handle body 4 about the pivot 33, so that the pivot 33 has a rotation axis 40 (see, for example, Figure 20) for the Define resistance element 17. As can be seen from FIGS. 17 and 18, two are in the grip body 4

Guide recesses 41 (see, for example, Figures 17 and 18) are formed, in which upon rotation of the resistance element 17, the free ends of the guide arms 35 can move in and in which the free ends of the guide arms 35 are arranged, when the functional body 30, the in the figures 17 to 20 rotational position occupies. During a rotational movement of the

Resistance element 17 thus lead the guide recesses 41, the movement of the free ends of the guide arms 35. In this case, the guide recesses 41 extend into one

Actuation direction 42 of the handle body 4, wherein the

Actuation direction 42 (see, for example, Figure 29) is defined as the direction in which the handle body 4 and its pivot lever 9 moves in a movement from the rest position in the direction of the end position or move.

Responsible for the translational and rotational movement of the resistance element 17 is the movement element 18 with its movement approach 19, which cooperates 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 at a movement of the handle body 4 of the

Resting position in the direction of the end position and a movement of the handle body 4 from a position lying between the intermediate position and the end position in the direction of the rest position in the path of movement of the movement approach 19 of the

Movement element 18 is arranged so that the movement element 18 endeavors to urge the functional body 30 of the resistance element 17 from the movement path. Figures 23 and 24 show again the structural details of the moving member 18, namely the pivot axis 12, the movement approach 19 and the coupling lugs 23 for movement coupling with the handle body 4. In Figures 25 and 26, two positions are further shown, the interaction of the moving element 18 and Show resistance element 17. In this case, Figure 25 shows a position in which the handle body 4 has been moved from the rest position in the direction of the intermediate position, so that the

Movement approach 19 of the moving member 18 comes into contact with the ramp surface 38 of the resistive element 17 and the

Resistance element 17 linear or translationally in the direction of the force increasing element 16 urges. The moving member 18 thus urges the resistance element 17 from its home position to its translational position when the handle body 4 moves from its rest position to its intermediate position. On the other hand, FIG. 26 shows a position in which the grip body 4 is moved out of the end position in the direction of the rest position, the movement attachment 19 of the movement element 18 also coming into abutment against the functional body 30 and the

Functional body 30 rotates about the rotation axis 40 or

rotatory moves. Consequently, the moving member 18 urges the resistance element 17 from its home position to its

Rotation position when the handle body 4 moves from a position lying between the end position and the intermediate position in the direction of its rest position.

With reference to FIGS. 27 to 39, the functioning of the door handle arrangement 3 according to the invention will now be described below

described. The figures 27, 29, 31, 33, 35 and 37 each show a sectional view, in which the section runs centrally through the door handle assembly 3. On the other hand, Figures 28, 30, 32, 34, 36 and 38 each show one

Sectional view in which the section runs just before one of the two guide arms 35.

In Figures 27 and 28, the handle body 4 in its rest position, in which the handle body 4 is unactuated, 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 Aufnähmerahmen 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 operation, the handle body 4 is actuated by an operator by pulling on the handle part 4a. In this pulling operation, the grip body 4 is pivoted about the rotation axis 10 in the counterclockwise direction (see arrow 43 in FIG. 29), the movement element 18 being clockwise due to the movement coupling of grip body 4 and movement element 18 (see arrow 44 in FIG

in the opposite direction to the handle body 4, about the pivot axis 12 rotates. In this movement of the handle body 4 from the rest position in the direction of the intermediate position of the movement approach 19 of the moving member 18 comes into contact with the ramp surface 38 of

Functional body 30, as can be seen from Figure 29. The resistance element 17 is still arranged in its basic position.

If the operator then continues to pull on the grip part 4a of the grip body 4, then the grip body 4 is further pivoted counterclockwise about the rotation axis 10, wherein due to the movement coupling, the movement element 18 pivots further about the pivot axis 12 in the clockwise direction. In FIGS. 31 and 32, the grip body 4 is in its intermediate position

reached, in which during normal operation of the door handle assembly 3, an electrical opening of the door 2 is effected by a button or sensor in a known manner in this position

is triggered, which sends a signal to the locking system 6 for the electrical opening of the door 2. The pulling operation of the handle body 4 by an operator in the direction of actuation 42 takes place against the resistance force 39, of the

Force increasing element 16 is exerted on the resistance element 17. For with a movement of the handle body 4 in the direction of the intermediate position shown in Figure 31 presses the

Movement approach 19 of the movement element 18 the

Resistance element 17 in the direction of the force increasing element 16th and moves the resistance element 17 in translation along the first guide surface 36 and the second guide surfaces 37. Due to the translational movement of the resistance element 17, the resistance element 17 compresses the force increasing element 16, which thereby generates the resistance force 39, which acts in the opposite direction of the translational movement. By the translational movement of the

Resistance element 17 applied force is felt by the operator of the door handle assembly 3, a force increase for pivoting the handle body 4. Before reaching the intermediate position shown in Figures 31 and 32, the door 2 is electrically opened in a normal operation of the door handle assembly 3 - as already mentioned above, so that an operator the handle body 4 at most unintentionally or too much force to the intermediate position or about the intermediate position

moved out. In the intermediate position of the grip body 4 of the movement approach 19 of the moving member 18 has reached a maximum of the ramp surface 38.

Summarizing Figures 29 to 32 is to be noted that upon movement of the handle body 4 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 resistive element 17 against the resistance force 39 of the force increasing element 16 in the direction of the force increasing element 16 linearly or.

translational with respect to the axis of rotation 10 of the handle body 4 along the first guide surface 36 and the second

Guide surfaces 37 is designed to move. During the movement of the grip body 4 from the rest position into the intermediate position, the movement element 18 is thus designed such that its movement approach 19 moves along the ramp surface 38 and the resistance element 17 is linear or translational with respect to the axis of rotation 10 of the grip body 4 in the direction of the force increasing member 16 so that the resistance element 17 compresses the force increasing member 16. In the in the Figures 31 and 32 shown intermediate position of the handle body 4, the resistance element 17 assumes a translational position.

In the translational position of the resistance element 17, the pivot pins 33 of the functional body 30 are at a distance from the bearing receivers 34 and the support elements 32 of the

Functional body 30 is arranged at a distance from the Aufnähmerahmen 31, wherein the functional body 30 within the

Capture frame 31 relative to its home position

arranged translationally, as it is already shown in Figures 14 and 16.

An electric opening of the door can thus during movement of the movement approach 19 of the moving member 18 along the

Ramp surface 38 or alternatively after exceeding the intermediate position, wherein the operator of the

Door handle assembly 3 during translational movement of the

Functional body 30 perceives a noticeably increasing resistance by the force increasing element 16, whereas when the intermediate position is exceeded by the operator

expended force for pivoting the handle body 4 noticeably decreases and possibly exceeding a

acoustic noise can be accompanied, which signals to the operator that he has reached or exceeded the actuation point for electrically opening the door 2.

In FIGS. 33 and 34, the grip body 4 is now actuated maximally by an operator and in its end position

arranged. In this case, the resistance element 17 after the

Passing through the intermediate position of the handle body 4 is now again arranged in its basic position. After the

Movement approach 19 of the moving member 18 has passed the ramp surface 38 of the functional body 30, presses that

Force increasing element 16 due to its elasticity the

Resistance element 17 from the translational position (see

FIGS. 31 and 32) back to its basic position (see FIGS. 33 and 34), so that the support elements 32 now open again the Aufnähmerahmen 31 of the handle body 4 rest and the

Trunnion 33 of the functional body 30 back into the

Bearing mounts 34 of the handle body 4 are arranged. The

Movement element 18 is in the movement of the handle body 4 beyond the intermediate position to the end position

spaced apart from the ramp surface 38.

During the movement of the grip body 4 from the rest position into the end position, the movement attachment 19 of the movement element 18 thus moves on the functional body 30 of the movement element

Resistance element 17 over and moves the resistance element 17, which in the path of movement of the movement element 18th

is arranged, at least temporarily translationally in the direction of the force-increasing element 16, as shown in Figures 27 to 34.

Upon movement of the grip body 4 from the end position in the direction of the intermediate position, the movement projection 19 of the movement element 18 moves toward the functional body 30 and comes into abutment against the functional body 30, as can be seen in FIGS. 35 and 36. In this case, the movement approach 19 of the moving member 18 is located at one of the ramp surface 38th

adjacent side surface 45 of the functional body 30 at. The functional body 30 has due to its storage of

Trunnion 33 in the bearing mounts 34 now the

Freedom of movement, around the pivot 33, which the

Rotary axis 40 define to rotate when the

Movement approach 19 of the moving member 18 due to the movement of the handle body 4 back to its rest position on the

Functional body 30 attacks and urges against it. The figures 35 and 36 show a position in which the

Functional body 30 already around the axis of rotation 40 in the

Bearing mounts 34 is arranged rotated counterclockwise, wherein the handle body 4 in this case in a clockwise direction 44 about the axis of rotation 10 and with the handle body. 4

motion-coupled movement element 18 against the Clockwise 43 rotates about the pivot axis 12. As already described for FIGS. 17 to 20, during the movement of the grip body 4 out of the end position into the rest position, the two guide arms 35 are at least temporarily in the

Guiding recesses 41 of the handle body 4 lying and guided arranged, wherein the moving member 18 on the functional body 30 comes into abutment and arranged with its two pivot 33 in the corresponding bearing mounts 34

Functional body 30 rotates counter to the direction of rotation of the handle body 4 in the bearing mounts 34 about the rotation axis 40 moves. In FIGS. 35 and 36, the resistance element 17 assumes a rotational position, in which the resistance element 17, which is rotated out of the basic position about the rotation axis 40, is arranged in the bearing receptacles 34.

During the movement of the grip body 4 from the end position back into the rest position, the movement attachment 19 of the movement element 18 thus moves on the functional body 30 of the

Resistance element 17 over and rotates the resistance element 17, which in the path of movement of the movement element 18th

is arranged, at least temporarily around the axis of rotation 40 and from the path of movement of the moving member 18, wherein the

Direction of rotation of the functional body 30 is directed against the direction of rotation of the handle body 4.

In summary, above is an inventive

Door handle assembly 3 has been described, which is characterized by the

Krafterhöhungseinrichtung 21 distinguished, which increases the actuation resistance for an operator noticeably upon actuation of the handle body 4. The force increasing means 21 comprises the elastically deformable and resistance force generating force increasing member 16 which is fixed to the grip body 4 cooperating with the force increasing member 16

Resistance element 17, which is both linearly movable and rotatably mounted on the handle body 4, and that with the

Resistive element 17 cooperating movement element 18, which the resistance element 17 during a movement of the

Handle body 4 from the rest position until reaching the

Intermediate position against the resistance force 39 generated by the force-increasing element 16 in the direction of

Force increasing element 16 translationally with respect to the

Rotational axis 10 of the handle body 4 and moving in a movement of the handle body 4 from the end position to the rest position rotationally with respect to a rotation axis 40 moving
