[0058] In the subsequent figures the identic reference signs are used for the same technical features even in different embodiments.

[0059] FIG. 1 shows a rear view of a door handle system 10 according to the invention which is assembled at the inner side 101.1 at the moveable part 101 of the vehicle 100. Therewith, from a mounted door handle 12 only the connecting means 12.3 are visible which serves for the fastening of the door handle 12 at the carrier 11. For this purpose at the carrier 11 a fastening element 15 is provided which is configured in form of a pusher. The fastening element 15 itself formfittingly retained via guidance means 11.1 at the carrier 11, wherein counter guidance means 8 in form of longitudinal holes are provided with enlargements at the fastening element 15. The fastening element 15 shown in FIG. 1 comprises a first section 15.3 and a second section 15.4, wherein the first section 15.3 corresponds mainly to a first part 15.5 and the second section 15.4 corresponds mainly to a second part 15.3 of the fastening element 15. The first section 15.3 serves thereby to secure a possibly existing locking cylinder 17 formfittingly at the carrier 11. In this FIG. 1 only the rear part of the locking cylinder 17 is shown which is connected with a lever for the transfer of the mechanic turning movement of the closing cylinder. The second section 15.4 serves for the fixation of the door handle 12, particularly by connecting means 12.3 of the door handle. The exact functionality is described in detail in FIGS. 3, 4, 5 and 6. Like it is shown in FIG. 1 the fastening element 15 is presently configured in two parts 15.5, 15.6, wherein the two parts are formfittingly connected with one another by the shown connecting means 15.7. These connecting means 15.7 can be configured from bolts which extend from the first part 15.5 of the fastening element 15 and which formfittingly interact with holes in the second part 15.6 of the fastening element 15. The adjustment elements 16 can be configured as rivets or screws. Further, it is possible that the two parts 15.5, 15.6 are materially bonded with one another. Like previously described it is also possible that the whole fastening element 15 is configured from one part.

[0060] In FIG. 1 at the left edge of the carrier 11 an acceptance 11.3 for an adjustment element 16 is shown which is shown in form of a screw 16.1. Likewise, the honeycomb-like structure of the carrier 11 with its reinforcement rips 11.4 is shown.

[0061] In FIG. 2a a detail enlargement of the left area of the carrier 11 with the adjustment element 16 is shown. Hereby, it is shown that the adjustment element 16 is configured as adjustment screw 16.1. The screw head is thereby formfittingly, but turnably arranged in the acceptance 11.3 of the carrier 11. Hereby, it is effected that the adjustment element 16 remains stationary at the carrier 11. The thread of the screw 16.1 interacts with the screw of the fastening means 15, particularly in the first section 15.3. Thereby, a turning of the screw through the existing through hole in the carrier 11 leads to a longitudinal displacement of the whole fastening element 15 in the direction of the shown arrow 25. Therewith, the fastening element 15 can be moved from a release position I in a fixing position II and back by a turning of the adjustment screw 16.1. Therewith, it is obvious that the whole door handle 12 can be moved between a release position I and a fixing position II only by an actuation of the adjusting element 16.

[0062] In the second FIG. 2b an optional configuration of the adjustment element 16 is shown comparable to the detail enlargement of FIG. 2a. Hereby, the adjustment element 16 is shown as a spring 16.2 which appropriately comprises a resting means 16.3. Like it is shown the adjustment element 16 is mounted in an acceptance 11.3 of the carrier 11. Thereby, initially the adjustment element 16 is mounted in the existing resting means 16.3 in recesses in the acceptance 11.3. In case the screw like adjustment element 16 is turned by a vehicle key projection in the head area the resting means 16.3 are getting out of the recesses and the spring 16.2 pushes the whole adjustment element 16 into direction of the shown arrow, wherein the fastening element 15 is transferred from its release position I in the fixing position II. For this purpose, the adjustment element 16 is rigidly connected with the fastening element 15. The assembly of such a configured door handle system according to the invention is particularly simple since the locking of the door handle 12 is achievable only by a slight turning of the adjusting element 16.

[0063] In the further FIG. 2c an enlargement of the right connecting means 12.3 of the door handle 12 of FIG. 1 is shown in exemplary form. Hereby, the head area of the connecting means 12.3 comprises contacts of the plug connection 19 which are electrically connectable with a counter plug connection at the carrier 11. Therewith, the fastening of the door handle 12 in the carrier 11 leads at the same time to an electrical connection of the part of the electronic unit 13 arranged in the door handle with the carrier 11 or the vehicle related electronic. Optionally, from at least one connecting means 12.3 a wire can be lead out with a plug connection 19 like shown in FIG. 1.

[0064] In FIG. 3 a door handle system 10 according to the invention with a partial cross section over the longitudinal extension 18 is shown. The fastening element 15 is thereby in a release position I, wherein the carrier 11 has already taken an assembly position III at the moveable part 101. Like it is shown the fastening element 15 is configured from two parts 15.5, 15.6. The first part 15.5 can thereby be configured as a casting in order to effect a particularly secure fastening of the lock cylinder 17 at the carrier 11. This lock cylinder 17 is formfittingly secured by a displacement of the fastening element 15 from the release position I into the fixing position II. Therefore, the fastening element 16 with its first section 15.3 is driven behind the projection of the lock cylinder 17, wherein a form fit is configured. The second part 15.6 of the fastening element 15 is configured metal sheet-like and comprises two through holes for the connecting means 12.3 of the door handle 12. In the mounting position III of the carrier 11 and the release position I of the fastening element 15 the door handle 12 is guided through the opening 101.3 in the moveable part 100, wherein at the same time the connecting means 12.3 are partially guided through the carrier 11. Like it is shown in FIG. 3 the door handle 12 comprises a longitudinal extension 18 wherein the door handle comprises two edges 12.2. At the two edges 12.2 the rod-like connecting means 12.3 extend which are mainly orthogonally adjusted to the longitudinal extension 18 of the door handle 12. Via this rod-like connecting means 12.2 the previously described sealings can be pushed.

[0065] In FIG. 4 it is shown how the carrier 11 is retained with a hook-like retaining means 11.2 in the mounting position III at the moveable part 101. Additionally, a fixation element 14 is provided in form of a screw in order to adjust and retain the carrier 11 exactly at the moveable part 101. The fixation element 14 is configured in form of a screw and is guided through the moveable part 101 at the outer side 101.2 and acts with a thread at the carrier 11 which is indicated in FIG. 4. Further, between the door handle 12 and the moveable part 101 a sealing 20 is provided around the opening 101.3.

[0066] From the further FIGS. 5 and 6 the locking of the door handle 12 at the carrier 11 is shown. For this purpose, the fastening element 15 is transferred from its release position I in its fixing position II through the actuation of the adjusting element 16. This transfer occurs in the present case through a pure linear movement of the fastening element 15. Hereby, the whole fastening element 15 is displaced along the guidance means 11.1 at the carrier 11. Hereby, corresponding longitudinal holes 15.9 are provided in the fastening element 15.

[0067] In FIG. 6 the generated form fit between the fastening element 15 and the door handle 12 is shown. For this purpose at the fastening element 15 the fastening means 15.1 configured as projections are provided which are brought into recesses or notches in the connecting means 12.3. These recesses or notches configure counter fastening means 12.4 for the fastening means 15.1. In order to facilitate the retraction of the fastening means 15.1 into the counter fastening means 12.4 leading inflow slopes 12.5 are provided at the counter fastening means 12.4 and the fastening means 15.1. Additionally, the fastening means 15.1 comprise preload means 15.2 as spring tongues, wherein an increased contact pressure of the door handle 12 at the outer side 101.2 of the moveable part 100 is affected. These preload means 15.2 are configured as trapezoid-like configurations of the fastening means 15.1, wherein the inclinations at the same time configure leading inflow slopes for the counter fastening means 12.4 of the door handle 12. The fastening means 15.1 extend into the counter fastening means 12.4 on both sides of the connecting means 12.3. Therewith, the punctual closing of the door handle 12 can be prevented, wherein likewise the stability of the fastening can be significantly increased.

[0068] FIG. 8 schematically shows in a perspective view the first part 30 and the second part 40 of the fastening element 15 during the assembly at a carrier 11 of a further door handle system 10 according to the invention. The second part 40 is preferably configured as a locking system and comprises an elastic deformable area at the end 42 facing the first part 30.

The carrier 11 comprises guidance means 11.1 which serve for a guidance of the mounted second part 40. The guidance means 11.1 are configured at two opposing sides of the carrier as wing like projections. The second part 40 comprises recesses/longitudinal holes 15.9 at its sides which serve for plugging on the second part 40 via the guidance means 11.1 of the carrier 11. This plugging on is shown in FIG. 8. The plug direction of the second part 40 to the carrier 11 is indicated with reference sign 44. The second part 40, the carrier 11 and the recesses/longitudinal holes 15.9 in the second part 40 and the guidance means 11.1 of the carrier 11 are configured and dimensioned such that during the plugging on of the second part 40 to the carrier 11 the elastic deformable end 42 of the second part 40 is deformed.

[0069] FIG. 9 schematically shows a perspective view of the first part 30 and the second part 40 of the fastening element 15 according to FIG. 8 during the coupling with one another. Meaning after the assembly of the second part 40 to the carrier 11 and the therewith connected deformation of the elastic deformable end 42 of the second part 40, the second part 40 is displaced from the mounting position III into release position II linear along the guidance means 11.1 of the carrier 11 until the counter coupling means 41, here in form of angular recesses, to which coupling elements 31 of the first part 30 rest due to its pretension caused by their deformation. After the resting of the counter coupling elements 41 to the coupling elements 31 configured as projections the second part 40 is coupled formfittingly and loss-proof to the first part 30.

[0070] FIG. 10 schematically shows in a perspective view the coupled fastening element 10 according to FIG. 9 in the fixing position II. The ring-like configured first part 30 of the fastening element 15 comprises a thread hole 32 for the acceptance of an adjusting element 16 arranged at the carrier 11. The adjusting element 16 serves for pulling out or guiding away the first part 30 by a turning. In FIG. 10 the first part 30 is transferred from the release position I into the fixing position II by a turning of the adjusting element 16 configured as a screw. In this fixing position II the first part 30 can retain a lock cylinder at the carrier 11 at therewith at the moveable part 101 of the door handle system 10 at least partially guided through the carrier 11 and the inner of the first part 30.
