(7) FIGS. 1a, 1b show an in-principle illustration of a door handle operator 1 for a motor vehicle door 100. The door lock operator 1 has a first switch 10, and a first pivot arm 30 which is mounted or mountable so as to be pivotable about a first rotation axis 21.1 of a first articulation 21, along a first degree of freedom 31, presently in relation to the motor vehicle door 100. The first pivot arm 30 has a further degree of freedom 32 which is perpendicular to the first rotation axis 21.1. The first switch 10 is operable by way of movement of the first pivot arm 30 along a first direction of the further degree of freedom 32. The first switch 10 is provided to be connected to an electric door lock 120 by way of a signal line 110, such that the electric door lock 120 is operable by way of the first switch 10. These figures furthermore also show the motor vehicle door system having the motor vehicle door 100, the door lock operator 1, and having the door lock 120, wherein the motor vehicle door 100 has the signal line 110 which connects the first switch 10 to the electric door lock 120.

(8) The non-operated state of the door lock operator 1 is shown in FIG. 1a. FIG. 1b shows the operated state which, proceeding from FIG. 1a, is achieved by traversing the first pivot arm 30 to the right, along the further degree of freedom 32.

(9) Furthermore, a preferred design embodiment of the further degree of freedom 32 by means of a mounting in an elongate bore is shown here. To this end, the first articulation 20 has an axle element 21.2 which is guided so as to be traversable in an elongate bore 21.3.

(10) FIGS. 2a-e, on the basis of FIGS. 1a and 1b, show various views of a preferred embodiment of a door lock operator 1 according to the invention, which presently and in an exemplary manner is conceived as an internal door handle, but which may also be designed as an external door handle. FIG. 2a shows a section through a front view, FIG. 2b shows an oblique perspective view from the left front/above, wherein the first pivot arm is only shown as a fragment, FIG. 2c shows an oblique perspective view of a detail of the upper region of the first articulation 21 from the left front and slightly from above, FIG. 2d shows a further oblique perspective view of a detail of the upper region of the first articulation 21 from the right front/above, FIG. 2e shows a further perspective view of a detail of the upper region of the first articulation 21 from the rear. While FIGS. 2a, 2b, 2c, and 2e show the door lock operator 1 in a state in which the first switch 10 is not operated, FIG. 2d shows a state in which the first switch 10 is operated.

(11) Along at least a part-region of the first degree of freedom 21, the first pivot arm 30 is impinged by a first spring element 11. The spring element 11 here is a preferred catch spring, coupled to the first switch 10. The first articulation 21 has a pivot arm sided part and a motor vehicle door sided part, the elongate bore 21.3 being present in the motor vehicle door sided part. The axle element 21.2 is a pin which on side is guided in the elongate bore 21.3 so as to be traversable in a manner perpendicular to the first rotation axis 21.1. On another side of the axle element 21.2, the pin is mounted in a bore 21.4 so as not to be traversable in relation to the first rotation axis 21.1. The pin is mounted in a rotationally fixed manner, the first pivot arm 30 being rotatably mounted on the pin.

(12) The door lock operator 1 has two stops 50, 50 which in a pivoted position of the first pivot arm 30 restrict movement of the pivot arm 30 along the further degree of freedom 32 more than in another pivoted position of the first pivot arm 30. The stop 50 beyond a specific outwardly pivoted state of the pivot arm 30 blocks the further degree of freedom. The stop 50 beyond a specific inwardly pivoted state blocks the further degree of freedom. The stops 50, 50 are configured as cams and are disposed on the pivot arm 30. At a specific angular position, said stops 50, 50 move into an intermediate space between the axle element 21.2 and a fixed part on the side of the vehicle door in the elongate bore 21.3, such that the axle element 21.2 cannot be traversed therein.

(13) The first pivot arm 30 has an operation portion which is to be manually pulled and to be manually depressed, the former therefore at the same time being an operation element 60. The operation element 60 in the region of the first articulation 21 has a pressure area 61.1 as an operation area 61, and a handle portion 62 having traction areas 61.2 as an operation area 61.

(14) In addition to the first switch 10, the door lock operator 1 has a coupling portion 33 for a mechanical operation means, presently for a Bowden cable, of the door lock 120. Thus, the operation element 60 by way of a Bowden cable is additionally connected or connectible to the door lock in a conventional manner.

(15) In order for the door lock 120 to be operated, the user may either depress the pressure area 61.1, on account of which the axle element 21.2 within the elongate bore 21.3 is traversed counter to the spring element 11 (to the position shown in FIG. 2d) and is thus pivoted in its entirety. On account thereof, the switch 10 is operated. By virtue of the operation of the switch, the door lock 120 is then electrically operated. Additionally, the user may traction the operation element 60 by way of the handle portion 62, thus operating the door lock 120 by way of the Bowden cable. In the case of this design embodiment, enhanced safety (in the case of an accident, for example) is provided by virtue of the redundant mechanical possibility for opening the door.

(16) FIG. 2f shows a variant of a design embodiment of the door lock operator 1 according to FIGS. 2a-e, in which the axle element 21.2 is guided so as to be traversable and rotatable in the elongate bore 21.3, and on the other side is mounted so as to be rotatable in the other bore. The first pivot arm 30 is mounted on the axle element 21.2 so as to be rotatable or to be rotatably fixed, or has the axle element 21.1 as a component part.

(17) FIGS. 3a-d and 4a-c, on the basis of FIGS. 1a and 1b, show various views of a door lock operator 1 according to the invention, which in an exemplary manner is presently conceived as an external door handle, but may also be designed as an internal door handle. FIGS. 3a, 3b, and 3d show the door lock operator 1 in a retracted position of the operation element 60 (see below), while FIGS. 4a, 4b, and 4c show a deployed position. FIG. 3a shows a plan view of the door lock operator 1. FIG. 3b shows a rear view of the first pivot arm 30 in the region of the first articulation 21. FIGS. 3c and 3d show the operation of the switch 10 (FIG. 3c) or of the switch 40 (FIG. 3d), respectively, in the retracted position of the operation element 60, and FIGS. 4b and 4c show the operation of the switch (FIG. 4b) or of the switch 40 (FIG. 4c), respectively, in the deployed position of the operation element 60.

(18) The door lock operator 1 has a further switch 40, and the further switch 40 is operable by way of movement of the first pivot arm 40 in a second direction, counter to the first direction, along the further degree of freedom 32. The first pivot arm 30 along a part-region of the first degree of freedom 31 is impinged by a first spring element 11, and along a further part-region of the first degree of freedom 31 is impinged by a further spring element 41, both spring elements 11, 41 here being preferred catch springs and each being coupled to the respective switch 10, 40. Thus, the pivot arm 30 in terms of the freedom of movement thereof in the one direction is limited in a force-dependent manner by the first spring element 11, and in the other direction by the second spring element 40. The first switch 10 and the second switch 40 are locationally fixed in relation to the first pivot arm 30.

(19) The axle element 21.2 is a pin which on one side of the axle element 21.2 in the elongate bore 21.3 is guided so as to be rotatable and traversable in a manner perpendicular to the first rotation axis 21.1, and on another side of the axle element 21.2, differing from FIGS. 2a-e, in a further elongate bore is likewise guided so as to be rotatable and traversable in relation to the first rotation axis 21.1. The axle element 21.2 per se is locationally fixed in relation to the motor vehicle door 100.

(20) The door lock operator 1 has a separate operation element 60 having an operation portion which is to be manually gripped and to be manually depressed. The operation element 60 by way of a second articulation 22 is mounted on the first pivot arm 30. The door lock operator 1 has a second pivot arm 70 which by way of a third articulation 23 is mounted or mountable so as to be pivotable in relation to the motor vehicle door 100. The operation element 60 by way of a fourth articulation 24 is mounted on the second pivot arm 70. The second, third, and fourth articulation each are pure rotary joints, the articulation axes of which are substantially parallel with the first rotation axis 21.1. The four articulations 21, 22, 23, 24 form a four bar linkage or a parallelogram linkage, respectively, wherein the respective axes of the first and third articulation 21, 23 are locationally fixed in relation to the vehicle door 100. The first pivot arm 30 along the further degree of freedom 32 by means of rotating movement of the operation element 60 which is performed about the fourth articulation 24 is bidirectionally traversable.

(21) The operation element 60 on either side of the fourth articulation 24 has at least one operation area 61. The operation areas 61 on either side of the fourth articulation 24 presently are pressure areas 61.1, 61.1, and traction areas 61.2.

(22) The operation element 60 by means of an actuator 80 by way of parallel traversing is alternatable between two positions. This is performed by means of rotating the first pivot arm 30 along the first degree of freedom 31. The one position is a position of the operation element 60 in which the latter is retracted into the motor vehicle door 100 (FIGS. 3a, 3c, 3d). The external face of the operation element 60 here terminates so as to be flush with the surface of the motor vehicle door 100. The other position is a position of the operation element 60 in which the latter projects from the motor vehicle door 100 (FIGS. 4a, 4b, 4c). Here, at least one traction area 61.2 is provided for the user for operating the door lock operator 1, and/or for pivoting open the motor vehicle door 100.

(23) The actuator 80, in an exemplary manner, presently has a gear box having a tappet which is linearly traversable and which impinges the second pivot arm 70 counter to a resetting installation 81 (a spring, for example), thus causing the fourth rotary joint 24 to be fixed in the respective position such that the operation element 60 may advantageously be pivoted about the axis of the fourth rotary joint 24 in order to achieve traversing of the first pivot arm 30 along the further degree of freedom 32.

(24) In the retracted position the operation element 60 has only pressure areas 61.1. The operation element 60 has a handle portion 62 which in one of these positions lies within the motor vehicle door 100, and which in the other of these positions projects from the motor vehicle door 100 and is manually grippable. In the position which projects from the motor vehicle door 100, the rear wall of the handle portion is flush with the surface of the motor vehicle door.

(25) The further degree of freedom 32 of the first pivot arm 30 is present in two mutually opposite directions in each of the two positions. As is shown in FIG. 3c, the first switch 10 may be operated by depressing the pressure surface 61.1 in the retracted position of the operation element 60; as is shown in FIG. 3d, the further switch 40 may be operated in the opposite direction by depressing on the pressure area 61.1 in the retracted position of the operation element 60. As is shown in FIG. 4b, the first switch 10 may be operated as before by depressing the pressure area 61.1 in the deployed position of the operation element 60, and, as is shown in FIG. 4c, the further switch 40 may be operated in the opposite direction by tractioning the traction area 61.2.

(26) A design embodiment in which the first articulation 21, which has the further degree of freedom 32, mounts the first pivot arm 30 in relation to the motor vehicle door is shown in FIGS. 3a to 4c. Alternatively, however, another of the four articulations may have the further degree of freedom 32, for example the articulation 23 which then in the context of the claims may be considered to be the first articulation, or in an analogous manner the articulations 22 or 24. Depending on the case, the pivot arm which is presently referenced as 70 is to be considered the first pivot arm in the context of the claims, and the pivot arm which is presently referenced as 30 is to be considered to be the second pivot arm.

(27) FIGS. 5a-5f, on the basis of FIGS. 1a and 1b, show various state of a further door lock operator 1 which in particular has a transmission lever 90. The latter, by way of rotation axis 90.1 which is aligned so as to be parallel with the rotation axis 21.1, is likewise rotatably mounted. The first pivot arm 30 and the transmission lever 90 here are disposed so as to be reciprocal, that is to say that the transmission lever 90 from the rotation axis 90.1 extends substantially in the direction of the rotation axis 21.1, and that the first pivot arm 30 from the rotation axis 21.1 extends substantially in the direction of the rotation axis 90.1. Moreover, the first pivot arm 30 and the transmission lever 90 are mutually overlapping. The transmission lever 90 lies between the switch 10 and the first pivot arm 30, in particular in relation to at least one transmission of force from the pivot arm 30 to the switch 10. The first switch 10 is operable by way of pivoting the first pivot arm 30 along a first direction of the first degree of freedom 31 (FIG. 5e). To this end, the first pivot arm 30 in the region of the first articulation 21 has an eccentric contour 34 which operates the switch 10 beyond a predefined specific pivoted angle, in the present example by way of the transmission lever 90 as a force/torque transmitter. The first pivot arm 30 along at least a part-region of the first degree of freedom 32 is indirectly impinged by a first spring element 11. In the case of this device it is preferable for the axle element 21.1 on one side of the axle element 21.2 to be guided in the elongate bore 21.3 so as to be traversable in a manner substantially perpendicular to the first rotation axis 21.1, and on another side of the axle element 21.2 to be guided in a further elongate bore, or in the same elongate bore which however is extended up to the other side, so as to be linearly traversable in a manner substantially perpendicular to the first rotation axis 21.1. The door lock operator 1 has a pivotably mounted transmission lever 90 which impinges the first switch 10, and which by the first pivot arm 30 by pivoting the first pivot arm 30 and/or by the movement of the first pivot arm 30 along the first direction of the further degree of freedom 32 is impingeable in such a manner that, on account thereof, the first switch 10 is operable by means of the transmission lever 90. The door lock operator 1 between the first pivot arm 30 and the transmission lever 90 has a transmission contact region 91 in which the first pivot arm 30 and the transmission lever 90 bear on one another. The transmission contact region 91 from an imaginary line 32.1 through the first rotation axis 21.1, which is parallel or collinear with the further degree of freedom 32, has a spacing . Moreover, a further transmission contact region 92 is present between the first pivot arm 30 and the transmission lever 90, the former being separated from the first transmission contact region 91 by a region in which there is no contact between the first pivot arm 30 and the transmission lever 90. The first pivot arm 30 bears on the transmission lever in these transmission contact regions 91, 92. Preferably, the first pivot arm 30 is urged against the transmission lever 90 by means of a spring element. The transmission contact region 91 is formed half-way between the rotation axis 90.1 and the rotation axis 21.1, on account of which advantageous uniformity of the required pressure force along the pressure area 61.1 results. The closer the transmission contact region 91 is displaced from here toward the rotation axis 21.1, the lower the required pressure force for operating the switch at the left end of the first pivot arm 30, that is to say that end that faces the rotation axis 90.1. In order of the transmission contact region to be defined, the transmission lever 90 has a protrusion which faces the first pivot arm 30. The second transmission contact region 92 is formed so as to be level in height with the rotary joint 21. The first pivot arm 30 has an operation portion that is to be manually pulled and/or to be manually depressed, the former thus at the same time being an operation element 60. The operation element 60 is manually and preferably by means of an optional actuator 80 alternatable between at least two positions. The operation element 60 has a pressure area 61.1 which is to be manually depressed, the operation element 60 by way of manual pressure on this pressure area 61.1 being manually pivotable from one of these two positions, the one of these two positions being a standby position of the operation element 60. The operation element 60 has a handle portion 62. The latter in one of these positions preferably lies substantially within the motor vehicle door 100, or is specified to lie therein. In the other of these positions, said handle portion 62 projects from the motor vehicle door 100, and is at least manually more readily grippable than in the one position. A stop 51 serves as an overload protector (FIG. 5e). While FIGS. 5a-5e are plan views, FIG. 5f shows an oblique view from slightly above; here, only the elongate bore 21.3 is more angular and less oval than in FIGS. 5a-5e, and lengths of levers are different; otherwise, this embodiment shown is analogous to those of FIGS. 5a-5e. The articulation 21 has an axle element 21.2 which is disposed so as to be rotationally fixed in the elongate bore 21.3, but is linearly traversable. The first pivot arm, for example by way of an actuator, may thus be torsioned by means of rotating the axle element 21.1 which is rotatably disposed in a housing (not shown).

(28) The various operation potentials resulting therefrom will now be described by means of FIGS. 5b-5e, switching of the switch 10 being in each case indicated by means of a small lightning flash. Commencing directly from the standby position of the operation element 60 (FIG. 5a), the switch 10 is operable by means of a pressure force in the region of the first articulation 21 (FIG. 5b) up to that end of the operation element 60 (FIG. 5c) that faces away from the pressure area 61.1, thus serving as a wide pushbutton. In the case of FIG. 5b, transmission of force from the first pivot arm 30 to the transmission lever 90 is increasingly performed by way of the transmission contact region 92, in the case of FIG. 5c increasingly by way of the transmission contact region 91. Furthermore, commencing from the standby position of the operation element 60 (FIG. 5a), the operation element 60 may be moved out of the standby position thereof to a projecting position (FIG. 5d) in that a manual pressure force is applied to the area 61.1, or in that a traction force is applied to the area 61.2 (to the extent that the latter is grippable) of the handle portion 62. Moreover, it is possible for an actuator to be coupled to the first pivot arm 30 to this end. Here, the first pivot arm 30 in the transmission contact region 91 is raised from the transmission lever 90. The switch 10 is then operable also from the position shown in FIG. 5d, in the simplest manner by means of continuing traction engaging on the area 61.2 (FIG. 5e).

(29) A new door lock operator which offers a large variety of employment possibilities for operating a door lock has been proposed herein. This is possible in particular by virtue of an articulation which has two degrees of freedom, a switch by way of which the door lock is operable or is operated, respectively, being operated by way of at least one of these degrees of freedom. The articulation here may serve directly as a mounting for an operation element, for example, (an internal door handle, for example), or be part of a complex gearbox, in particular of a four bar linkage, for example, which permits very comfortable and at the same time aerodynamic or protected (against dust/dirt/damage) positioning of an operation element.
