DETAILED DESCRIPTION

(6) A motor vehicle 1 having a motor vehicle door 2 according to the proposal is illustrated in FIG. 1a. As for the meaning of the term “motor vehicle door”, reference may be made to the introductory part of the description. In particular, the motor vehicle door 2 can be any type of the motor vehicle doors 2 mentioned at the outset.

(7) The motor vehicle door 2 from FIG. 1a is illustrated in FIG. 1b. Said motor vehicle door 2 has an activation installation 3 according to the proposal. The activation installation 3 has a distribution installation 4 and a flexible transmission means 5.

(8) The distribution installation 4 has a first input 6 and a first output 7 as well as a second output 8. Said distribution installation 4 is furthermore configured for distributing an activation movement to two functional units 9, 10. The first functional unit 9 and/or the second functional unit 10 herein can be assigned to the activation installation 3. The first functional unit 9 herein can be a motor vehicle lock 9a, and the second functional unit 10 herein can be a secondary lock 10a and/or a door arrester 10b.

(9) According to the proposal, the flexible transmission means 5 can be configured for transmitting the activation movement at least in portions from the distribution installation 4 to the first functional unit 9, or for transmitting the activation movement at least in portions from the distribution installation 4 to the second functional unit 10. A transmission means 5a for transmitting the activation movement at least in portions from the distribution installation to the second functional unit 10 can be provided in the exemplary embodiment, and a further transmission means 5b for transmitting the activation movement at least in portions from the distribution installation 4 to the first functional unit 9 can be provided in the exemplary embodiment.

(10) The concept that underlies various embodiments is now that in the assembled state of the activation installation 3, on a first portion of an activation movement that acts on the first input 6 of the distribution installation 4, the first input 6 for transmitting the activation movement in portions to the second functional unit 10 is coupled or is to be coupled to the second output 8, and that at the commencement of a second portion of the activation movement, the first input 6 and the second output 8 for interrupting the transmission of the activation movement to the second functional unit 10 are decoupled.

(11) On account thereof it is possible for an activation movement to be distributed to the two functional units 9, 10 in a particularly advantageous manner. If the first functional unit 9 is a motor vehicle lock 9a, in particular a primary lock, and if the second functional unit 10 is a door arrester 10b and/or a secondary lock 10a, by way of an activation movement on a first portion a clearance that is provided in the transmission means 5 and/or in the primary lock can first be travelled through, while the door arrester 10b and/or the secondary lock 10a is already being opened or released, respectively, such that on the second portion of the activation movement, following decoupling of the second functional element 10, thus in particular of the door arrester 10b and/or of the secondary lock 10a, force no longer has to be applied for the further adjustment of the second functional unit 10, and the force can be used for adjusting the first functional unit 9, thus the motor vehicle lock 9a herein. On account thereof, the effort in terms of force required, or the activation path required, respectively, is reduced by virtue of a gearing that is to be chosen so as to be higher. This leads to an increase in comfort for the user.

(12) In a corresponding manner it is possible that in the assembled state of the activation installation 3, on a second portion of an activation movement that acts on the first input 6 of the distribution installation 4, the first input 6 for transmitting the activation movement in portions to the first functional unit 9 is coupled or is to be coupled to the first output 7, and/or that in the assembled state of the activation installation 3, on a first portion of an activation movement that acts on the first input 6 of the distribution installation 4, the first input 6 for transmitting the activation movement in portions to the first functional unit 9 is coupled or is to be coupled to the first output 7.

(13) As has already been described above, the activation installation 3 can have the first functional unit 9. The latter can be a motor vehicle lock 9a, in particular a primary lock. Said motor vehicle lock 9a can be capable of being moved to different locking states. The latter can in particular be at least two or three of the locking states “unlocked”, “locked”, “anti-theft locked” and/or “child locked”. The first output 7 in the exemplary embodiments is coupled to an external activation lever 9b of the motor vehicle lock 9a.

(14) The actuation installation 3 can furthermore have the second functional unit 10. The latter herein can be a secondary lock 10a and/or a door arrester 10b. A secondary lock 10a in the closed state of the motor vehicle door 2 additionally locks the latter to the vehicle body. A door arrester 10b serves for holding the motor vehicle door 2 at least in an opened, in particular a fully opened, position. The second output 8 in the exemplary embodiment is coupled to a release lever 10c of the secondary lock 10a and/or to a release lever 10d of the door arrester 10b, in particular by way of the flexible transmission means 5, 5a.

(15) In order for the activation movement to be transmitted at least in portions from the first output 6 to the first functional unit 9, the activation installation 3 has a further transmission means 5b. The further flexible transmission means 5b herein can couple to the first output 7 to the external activation lever 9b, or according to an alternative design embodiment to the internal activation lever 9c of the motor vehicle lock 9a.

(16) In order for the activation movement to be generated, the activation installation 3 herein can have a door handle 11, in particular an internal door handle 11b and/or an external door handle 11a, which acts on the first input 6 of the distribution installation 4. The door handle 11 can act on the first input 6 by way of a flexible transmission means 5, 5c.

(17) The first input 6 and the first output 7 in the exemplary embodiments can be formed by a first coupling element 12. As is shown in the exemplary embodiment, the first coupling element 12 can be configured so as to be integral. Particularly, the transmission means 5c at the first input 6, and the first coupling element 12 and/or the transmission means 5b at the first output 7, and the first coupling element 12 are configured so as to be integral, as is the case in all exemplary embodiments. However, in an alternative design embodiment, the coupling element 12 for example can also be configured so as to be integral, and the transmission means 5b at the first output 7 and/or the transmission means 5c at the first input 6 can be releasably connected to the coupling element 12. The connection between the first coupling element 12 and the transmission means 5, or the plurality of transmission means 5, respectively, can in this instance be designed as a snap-fit connection, for example.

(18) The first coupling element 12 herein can have a substantially cuboid shape. Alternatively, the first coupling element 12 can however also have a cylindrical shape, for example. The distribution installation 4 has a guide 13 for guiding the movement of the first coupling element 12. The guide 13 herein can be provided by a housing 14. The housing in the exemplary embodiment is the housing 14 of the distribution installation 4. The distribution installation 4 herein can be disposed separately from the first functional element 9, separately from the second functional element 10, and separately from the door handle 11.

(19) However, in an alternative design embodiment (not shown), it can also be provided that the distribution installation 4 is assigned to a motor vehicle lock 9a. In this case it can be that the distribution installation 4 is disposed in a housing 15 of the motor vehicle lock 9a. The housing 15 of the motor vehicle lock 9a can provide the guide in this instance.

(20) Alternatively, the distribution installation 4 can also be disposed in a housing of the secondary lock 10a and/or of the door arrester 10b.

(21) Alternatively, it can furthermore be provided that the distribution installation 4 is assigned to the door handle 11. In this case, the guide can be provided by a support structure 16 of the door handle 11, for example.

(22) The second output 8 is formed by a second coupling element 17. The latter can be also configured so as to be integral. In particular, said second coupling element 17 can also be configured so as to be integral to the transmission means 5a at the second output 8, as is the case at least in the exemplary embodiments of FIGS. 2 and 4a. However, for example, the second coupling element 17 can also be releasably connected to the transmission means 5a, for example by means of a snap-fit connection.

(23) Various design embodiments of the coupling element 17 are moreover possible. The second coupling element 17 herein can be configured so as to be displaceable (cf. FIGS. 2 and 4a) and/or in the manner of a lever (cf. FIGS. 3 and 4b).

(24) The second coupling element 17 for decoupling can have a deflection contour 17a which for decoupling the second output 8 from the first output 6 slides on the first coupling element 12, on account thereof decoupling the second coupling element 17 from the activation movement.

(25) The second coupling element 17 can also have a guide 18. The second coupling element 17 herein can be guided by the guide 18 and by the first coupling element 12. As is shown in FIG. 2, the guide 18 can have a decoupling portion 18a which enables decoupling of the second coupling element 17 from the first coupling element 12.

(26) The activation movement in the exemplary embodiment of FIG. 2 acts on the first input 6. The first coupling element 12 correspondingly covers the distance of an activation path. On the first activation portion of the activation movement the first coupling element 12 transmits a portion of the activation movement to the second coupling element 17. When the decoupling portion 18a is reached, the second coupling element 17 by sliding on the deflection contour 17a decouples from the first coupling element 12. The second coupling element 17 herein can be also moved at least transversely to the activation movement. As a result, an activation path that is longer for the first coupling element 12 than for the second coupling element 17 can be created. The movement of the second coupling element 17 herein can be performed in a purely translatory manner.

(27) Herein it can apply furthermore that the second coupling element 17 following decoupling remains decoupled from the first coupling element 12 for at least until the first coupling element 12 again completes a movement counter to the activation movement, such as until said first coupling element 12 has been returned to the decoupling position.

(28) The second coupling element 17 in the exemplary embodiment of FIG. 3 is not configured so as to be displaceable, but rather in the manner of a lever. The lever-type second coupling element 17 has a coupling point 17b which forms the second output 8. Said second coupling element 17 herein can be rotatably mounted on the housing 14 by way of a centre of rotation 17c. The coupling point 17b can be disposed so as to be closer to the rotation axis of the coupling element 17 than the deflection contour 17a. A variation in the gearing of the activation movement is enabled on account thereof. Said variation in the gearing can be utilized for adapting the force or adapting the path, respectively, of the activation movement when the latter is distributed to the second functional element 10.

(29) The deflection contour 17a herein can be formed by a cylindrical portion. If an activation movement acts now on the first input 6, the first coupling element 12 likewise covers the distance of a corresponding activation path. On the first activation portion of the activation movement the first coupling element 12 by way of the deflection contour 17a transmits a portion of the activation movement to the second coupling element 17. Said deflection contour 17a herein can be configured as a pin. The second coupling element 17 that is configured in the manner of a lever is deflected. The deflection contour 17a in this case slides on the first coupling element 12, decoupling the second coupling element 17 on a second portion of the activation movement. Here too, the second coupling element 17 can remain decoupled from the first coupling element 12 at least until the first coupling element 12 completes a movement counter to the activation movement.

(30) The activation arrangement 3 can furthermore also have a second input 19 and/or a third output 20. Two exemplary embodiments relating thereto are shown in FIG. 4. Said two exemplary embodiments moreover are configured in a manner substantially identical to that of the activation arrangements of the exemplary embodiments of FIGS. 2 and 3.

(31) In this instance, in the assembled state of the activation installation 3, on a first portion of an activation movement that acts on the second input 19 of the distribution installation 4, the second input 19 for transmitting the activation movement in portions to the second functional unit 10 can be coupled or is to be coupled to the second output 8. In this instance, at the commencement of a second portion of the activation movement, the second input 19 and the second output 8 for interrupting the transmission of the activation movement to the second functional unit 10 are decoupled.

(32) According to the third and the fourth exemplary embodiment (FIG. 4) it can be that the distribution installation 4 has a third output 20, and that in the assembled state of the activation installation 3, on a first portion of an activation movement that acts on the second input 19 of the distribution installation 4, the second input 19 for transmitting the activation movement in portions to the first functional unit 9 and/or to a third functional unit (not shown) is coupled or is to be coupled to the third output 20. Additionally or alternatively, in the assembled state of the activation installation 3, on a second portion of an activation movement that acts on the second input 19 of the distribution installation 4, the second input 19 for transmitting the activation movement in portions to the first functional unit 9 and/or to a third functional unit (not shown) can be coupled or is to be coupled to the third output 20.

(33) In order for the activation movement to be transmitted at least in portions from the third output 20 to the first functional unit 9 or to the third functional unit, the activation installation 3 herein can have a further flexible transmission means 5d. The further flexible transmission means 5d herein can couple the third output 20 to the internal activation lever 9c or to the external activation lever 9b of the motor vehicle lock 9a.

(34) The activation installation 3 herein can have a further door handle 11, in particular an internal door handle 11b and/or an external door handle 11a, which acts on the second input 19 of the distribution installation 4. The further door handle 11 herein acts on the second input 19 by way of a flexible activation element 5e.

(35) In the exemplary embodiments of FIG. 4, the second input 19 and/or the third output 20 are/is formed by a third coupling element 21. Here too, the third coupling element 21 is configured so as to be integral.

(36) In terms of the design embodiment of the third coupling element 21 and of the transmission means 5d, 5e that engage on the third coupling element 21 reference is made to the explanations pertaining to the first coupling element 12. The first coupling element 12 and the third coupling element 21 can be of identical design. However, the lengths of the transmission means 5 that engage on the coupling elements 12, 21 can differ.

(37) The third coupling element 21 can be guided by a guide 22. The latter herein can be configured by the housing 14. In an activation movement that acts on the second input 19, the second coupling element 17 herein can be guided by the guide 18 and by the third coupling element 21.

(38) In order for the second output 8 to be decoupled from the first input 6 and/or the second input 19 during the commencement of a second portion in the activation movement, the second coupling element 17 herein by the first coupling element 12 and/or the third coupling element 21 can be moved out of the movement path of the first coupling element 12 or of the third coupling element 21, respectively. This can be performed in a manner such as has already been described above for the exemplary embodiments of FIGS. 2 and 3 in the context of the first and the second coupling element 12, 17.

(39) The activation movements of the first and of the third coupling element 12, 21 can run in parallel. The activation movement that is transmitted in portions to the second coupling element 17 can likewise run so as to be parallel with the activation movement of the first and/or the third coupling element 12, 21. However, the activation movement of the second coupling element 17 do not run in a common plane shared with the activation movements of the first and of the third activation element 12, 21.

(40) It is finally to be pointed out that the flexible transmission means 5, 5a, 5b, 5c, 5d, 5e herein can be Bowden controls. However, these can also be cables.
