Abstract
Description
[0001] The invention relates to a door assembly for a vehicle door, a door module for such a door assembly, and a vehicle door with such a door assembly.
[0002] A vehicle door typically has a door body or door frame as its framework or basic structure. Such a door frame comprises an outer door panel (outer door sheet) forming the outer skin of the vehicle door and an inner door panel (inner door sheet) connected to the outer door panel on the vehicle's interior side. Between these panels is a cavity that serves as a mounting space for functional elements or door components, such as a window regulator, a door lock, an airbag, or similar items.
[0003] Since moisture can penetrate the cavity between the outer and inner parts of the door, also referred to below as the door interior, for example via the door sill slot for the insertion of a window pane which closes a window opening in the vehicle door, the cavity is divided by means of a wet-dry space separation into a wet space facing the vehicle environment or the outer part of the door (wet space side) and a dry space facing the vehicle interior or the interior trim (dry space side).
[0004] The inner part of the door, or the door frame, which is connected to the outer part of the door, typically has two opposing, spaced-apart side frame sections and a sill section connecting them, as well as a lower frame sill section (door bottom).
[0005] The sill section, oriented in the longitudinal direction of the vehicle (X-direction in the vehicle coordinate system), together with the side frame sections oriented in the direction of the vehicle height (Z-direction in the vehicle coordinate system) and the sill section connecting them to the bottom of the door and extending in the X-direction, defines a frame cutout (door cutout) of the inner door part (door shell). In the assembled state of the vehicle door, this frame or module cutout is at least partially, preferably completely, covered by a substantially plate-like or plate-shaped component carrier (door module carrier, functional carrier, base carrier) of a door module.
[0006] Various functional components of the vehicle door, such as window regulators, drive units, side airbag modules, speakers, control units, or the like, can be pre-mounted on the door carrier. The pre-assembled door carrier, also known as the door module, serves in particular to separate a wet compartment formed between the outer door panel and the door module from a dry compartment formed between the door module (door module carrier) and the inner door panel of the vehicle door, especially for moisture-sensitive functional components of the door module.
[0007] The door carrier thus creates a wet / dry compartment separation within the vehicle door during assembly. Typically, at least some door components, such as a door lock or a (side) door drive, are located in the wet compartment. In other words, these wet compartment components are usually pre-mounted on the wet compartment side of the door carrier. These wet compartment components therefore require appropriate sealing against the ingress of water or moisture.
[0008] It is possible that some door components on the door module, in their intended final assembly position, protrude beyond the outer contours of the door module, i.e., the outer circumference of the assembly carrier (e.g., door lock, door drive, cable interface to an A-pillar, etc.). In the context of an installation in a vehicle side door, the pre-assembled door components thus protrude, for example, in the Z-direction (vehicle height direction in the vehicle coordinate system) and / or in the X-direction (vehicle length direction in the vehicle coordinate system). The door components therefore project laterally beyond the edge of the assembly carrier, and consequently also beyond the opening edge of the mounting hole in the inner door panel.
[0009] For typical wet-room components, such as door locks, any component protrusion necessitates interrupting the continuous sealing path of the door module or the component carrier, thus requiring additional sealing materials to achieve the wet-dry room separation. In particular, such a wet-room door lock requires additional sealing in the area of the lock jaw.
[0010] Another problem is that with conventional door frame designs, it is not possible to mount a door module with a component overhang in the Y-direction (the vehicle's transverse direction in the vehicle coordinate system). Therefore, mounting the door module to the door frame requires either a pivoting and folding motion, or the protruding door component is only moved into its final position (pivoted, folded, or shifted) after the module has been mounted to the door frame.
[0011] The invention is based on the objective of specifying a particularly suitable door assembly for a vehicle door. In particular, a door assembly is to be specified for which a particularly simple assembly of a door module with a component protrusion is enabled. The invention is further based on the objective of specifying a particularly suitable door module for such a door assembly, and of specifying such a door assembly comprising a particularly suitable vehicle door.
[0012] With regard to the door assembly, the problem is solved according to the invention by the features of claim 1, with regard to the door module by the features of claim 12, and with regard to the vehicle door by the features of claim 13. Advantageous embodiments and further developments are the subject of the dependent claims. The advantages and embodiments mentioned with regard to the door assembly are also transferable mutatis mutandis to the door module and / or the vehicle door, and vice versa.
[0013] The conjunction “and / or” is to be understood here and in the following as meaning that the features linked by means of this conjunction can be both common and alternative to each other.
[0014] The door assembly according to the invention is designed, suitable, and configured for use in a vehicle door. The door assembly is specifically designed for a side door and comprises a door frame with an inner door section. The inner door section has a mounting opening onto which a door module is attached. The door module has a mounting bracket and at least one door component pre-mounted on the mounting bracket. The door component projects at least partially beyond the outer circumference or edge of the mounting bracket. In other words, the door component has a component projection.
[0015] In this and the following, an "aggregate carrier" refers specifically to a flat component on which the door component(s) can be (pre-)mounted. The aggregate carrier has at least one support or mounting surface for the arrangement of the respective door component.
[0016] The component carrier can be made of a metal, for example, steel or an aluminum alloy. Preferably, the component carrier is made at least partially of a composite or plastic material. This means, for example, that part or several parts of the component carrier are made of a plastic material. Preferably, a large proportion of the component carrier, i.e., more than 40% or 50% of the component carrier, and in particular the support or mounting surfaces defined by the component carrier for arranging the door components, are formed from the plastic material. For example, a fiber-reinforced plastic, preferably long-glass-fiber-reinforced polypropylene or an organosheet, is used as the plastic material.
[0017] In the following, a "door component" refers specifically to an electrical and / or mechanical functional element of the vehicle door, which is part of a door module or a pre-assembled door module assembly, and which, in a pre-assembled position, projects beyond the edge of the door module or its mounting bracket. Thus, in the pre-assembled position of the door component, the door module or mounting bracket exhibits a component or assembly projection relative to the door component.
[0018] The door component is preferably designed as a door lock and will be referred to as such below. However, the following descriptions for a door lock can also be applied analogously to other door components, such as a door drive or a door disconnect point of a wiring harness.
[0019] In the following, "protruding" or "assembly or component overhang" refers in particular to a section or part of the door component that extends beyond the outer circumference or outer edge of the aggregate carrier in a lateral direction, i.e., in the plane of the aggregate carrier.
[0020] The following information regarding spatial directions, particularly in a vehicle coordinate system, is given for an exemplary installation situation of the door module in the unfinished door frame of a side door of the vehicle. The abscissa (X-axis, X-direction) is oriented along the longitudinal direction of the vehicle (direction of travel), the ordinate (Y-axis, Y-direction) along the transverse direction of the vehicle, and the application axis (Z-axis, Z-direction) along the vehicle height.
[0021] In the pre-assembled position, the door component therefore protrudes at least partially beyond the outer circumference of the assembly carrier in the ±X or ±Z direction. In other words, the assembled door module has a mounting or component overhang in the ±X or ±Z direction.
[0022] According to the invention, the inner door panel has a molded-on receptacle for the door component, which is open in a direction perpendicular to the plane of the inner door panel. For example, the receptacle is designed as a recess in the inner door panel that is brought into the vertical direction. The receptacle is thus open, in particular, in the Y-direction. This allows the door module to be mounted perpendicular to the inner door panel. In other words, a purely Y-shaped mounting of the door module to the door frame is possible, enabling particularly simple and cost-effective module assembly at the original equipment manufacturer (OEM).
[0023] In its assembled state, the door module preferably provides a wet-dry compartment separation for the vehicle door or the door assembly. For this purpose, the door module or the assembly carrier has a sealing element. This sealing element is located on the wet-compartment side of the assembly carrier, i.e., on the side facing the environment. The seal to the inner door part is preferably in a vertical direction, i.e., along the Y-direction. With the door assembly according to the invention, the mounting direction of the door module is thus essentially identical to the direction of force of the seal, enabling a particularly reliable wet-dry compartment separation.
[0024] In an advantageous embodiment, the dry-room component is arranged or pre-assembled on a dry-room side of the assembly carrier, i.e., on a side facing the vehicle interior. In other words, the door component is designed as a dry-room component. By incorporating the inner door panel, it is particularly possible to relocate door components, which are typically pre-assembled as wet-room components on the wet-room side of the assembly carrier, to the dry side. This eliminates the need for additional seals on the wet-room side. Furthermore, the sealing path on the wet-room side is not interrupted by the protruding door component and is therefore independent of the inner door panel's placement.
[0025] When the door component is designed as a door lock, a dry-room lock is implemented for the door assembly. This eliminates the need for wet-room contact at the door lock. Furthermore, no additional sealing is required in the area of the lock jaw. Additionally, the design of the door lock can be simplified due to its dry-room orientation, resulting in a particularly cost-effective door module, which in turn positively impacts the overall cost of the door assembly.
[0026] In one conceivable embodiment, particularly in the case of a door lock as a door component, the door component is pre-mounted on the aggregate carrier, projecting in the transverse direction, i.e. in the +X or -X direction.
[0027] In a further advantageous embodiment, the door component is mounted on a plate element that is pre-assembled to the assembly carrier with an overhang at the edge. The door component, for example, the door lock, is arranged on the plate element, which acts as a mounting or retaining plate, and is indirectly attached or pre-mounted to the assembly carrier via the plate element. The plate element is located on the dry-room side and is attached to the assembly carrier. The plate element thus serves as a door lock holder. If the door component is designed as a door drive, the plate element serves, for example, as a door drive holder.
[0028] In one possible design, the recess is embossed as a depression or indentation in the inner door panel. This ensures simple and cost-effective manufacturing of the inner door panel.
[0029] The door module is preferably mounted in the Y-direction on the inner door panel, so that the door components are inserted into the receptacle perpendicular to the plane of the inner door panel (XZ), with the plate element covering the receptacle like a lid. In particular, the plate element is attached to the inner door panel. The plate element is thus designed as a reinforcing plate or sheet, which forms a closed profile around the perimeter or in certain areas together with the door frame and thus contributes to the door's rigidity. The plate element can therefore, for example, serve as both a door lock holder and a lock reinforcement, thus achieving advantageous functional integration.
[0030] The mounting bracket, for example, has a hole-like mounting opening that completely passes through the bracket as a through-hole. This mounting opening is, for example, a screw point.
[0031] In this context, and in the following, a "screw point" refers specifically to a location on the component carrier designed to receive a fastening screw, thereby creating a secure and reliable connection between the component carrier and one or more components, particularly a door component and / or the door frame. Such a screw point comprises a screw hole in the form of the fastening opening, which extends completely through the component carrier.
[0032] The screw point serves, for example, to screw the door component, in particular the panel element, onto the assembly carrier and / or to screw the assembly carrier to the door frame, in particular to the inner door panel, by means of a fastening screw. The screw point is thus designed, for example, as a fastening point for attaching the door module or assembly carrier to the inner door panel, wherein the assembly carrier or the screw point is penetrated by the fastening screw in the fastened state, and wherein the fastening screw is, for example, screwed into a threaded hole or a threaded nut for fixing to the inner door panel. The door component has a corresponding fastening opening, which is arranged coaxially with the fastening opening of the screw point for (pre-)assembly.
[0033] In this and the following, "axial" or an "axial direction" refers specifically to a direction parallel (coaxial) to a central axis of the mounting opening, i.e., perpendicular to the sides of the mounting opening. Similarly, in this and the following, "radial" or a "radial direction" refers specifically to a direction oriented perpendicular (transverse) to the central axis of the mounting opening along a radius of the mounting opening. In this and the following, "tangential" or a "tangential direction" refers specifically to a direction along the circumference of the mounting opening (circumferential direction, azimuthal direction), i.e., a direction perpendicular to both the axial and radial directions.
[0034] An additional aspect of the invention provides that the door component is clipped to the mounting opening for pre-assembly by means of a separate mounting clip. In particular, the panel element is clipped to at least one mounting opening by means of such a mounting clip. The mounting clip passes through the mounting openings of the door component and the assembly carrier and thus secures them by means of a positive and / or non-positive locking connection.
[0035] The separate mounting clip allows door components to be attached or pre-assembled to existing mounting holes, screw points, or other openings in the door frame. Screwing the door frame to the door structure permanently fixes the door component in its position, enabling it to fulfill structural functions.
[0036] The terms "clip fastening" or "clip-fastened" refer here and in the following to a snap-fit or locking mechanism that connects at least two components (in this case, in particular, a fastening clip, a door component, a mounting bracket, or a fastening screw). Such a clip fastening, for example, features an interlocking or overlapping of corresponding contours that form a detachable connection.
[0037] The term "positive locking" or "positive locking connection" between at least two interconnected parts is understood here and in the following to mean, in particular, that the cohesion of the interconnected parts in at least one direction is achieved either through a direct interlocking of the contours of the parts themselves or through an indirect interlocking via an additional connecting element. The "blocking" of mutual movement in this direction is thus due to the form.
[0038] In the following, a "force-fit" or "force-fit connection" between at least two connected parts is understood to mean, in particular, that the connected parts are prevented from sliding against each other due to a frictional force acting between them. If a "connecting force" that generates this frictional force is absent (this means the force that presses the parts against each other, for example, a screw force or the force of gravity itself), the force-fit connection cannot be maintained and can therefore be broken.
[0039] In a preferred embodiment, the fastening clip has a cuff-like (tubular, hollow cylindrical) sleeve body with a central through-hole for the passage of a fastening screw's shank. The sleeve body further features a flange collar, preferably integrally molded on its end face, as a bearing surface for the screw head of a fastening screw. The sleeve body also includes at least one radially flexible locking tab (clip tab) with a free-end locking lug (clip lug) for positive and / or force-fit clip attachment to the fastening opening. This results in a particularly suitable fastening clip for pre-assembly of the door component.
[0040] For clipping, the sleeve body is inserted into the mounting holes of the door component and the assembly carrier, thereby adjusting the locking tab radially inwards into the through-hole of the sleeve body. The resulting mechanical preload causes the locking tab to automatically move radially outwards again after passing through the mounting holes, so that the locking lug engages behind the edge of one of the mounting holes. This creates a radial and axial positive locking connection via the mounting clip, which secures the door component to the assembly carrier. In the clipped state, the sleeve body is thus seated in the two mounting holes of the door component and the assembly carrier, with the flange collar projecting radially beyond one edge of the opening, and the opposite edge of the opening being positively engaged by the locking tab or locking lug.
[0041] The sleeve body is designed, for example, as a segmented ring wall with a number of ring wall sections, wherein a locking tab for clip attachment is arranged between each pair of adjacent ring wall sections. Preferably, the sleeve body has several, i.e., at least two, preferably three locking tabs, so that, preferably in the clipped state, a three-point mounting, arranged particularly symmetrically, is realized, which provides the locking lug rear grips.
[0042] Starting from the flange collar, the locking tabs preferably extend over the entire axial length of the sleeve body and protrude axially upwards at the end face of the sleeve body at least by means of a tab section having the locking lugs.
[0043] In a suitable further development, a raised retaining sleeve is formed on the flange collar as an annular collar for receiving a fastening screw, which is aligned coaxially to the sleeve body, wherein the retaining sleeve has a number of radially inwardly projecting retaining lugs for axially holding a fastening screw, in particular a screw head, in a pre-assembly position.
[0044] The retaining sleeve and the sleeve body are integrally formed on opposite flat sides of the approximately annular flange collar, wherein the sleeve body encloses a radially inner annular opening as the opening of the central through-hole, and wherein the retaining sleeve is in particular arranged circumferentially on an outer circumference of the flange collar.
[0045] The ring collar or retaining sleeve acts in particular as a positioning aid when inserting the fastening screw.
[0046] The retaining lugs are integrally formed, i.e., monolithically, on the inner circumference of the retaining sleeve. This ensures a particularly stable connection of the retaining lugs. The retaining lugs have a fixed end that is fixed to the ring collar and a free end designed to hold the screw head in the pre-assembled position. The free end is preferably designed to be flexible or spring-like.
[0047] The retaining sleeve is designed, for example, as a closed, continuous circular cylinder or as a pipe section, so that the fixed ends are particularly stable and rigid. In a possible further development, the retaining sleeve is segmented, meaning that it has a number of axially extending slots or breaks. This gives the ring segments of the retaining sleeve a certain degree of compliance or flexibility, particularly along a radial direction, which has a beneficial effect on the retaining lugs attached to them. In particular, this simplifies the locking or clipping of the screw head to the retaining lugs in the pre-assembly position.
[0048] Preferably, the retaining sleeve has two types of retaining lugs. For example, a number of first retaining lugs are integrally formed on the retaining sleeve to provide axial support for the screw head, and a number of second retaining lugs are integrally formed to provide axial securing for the screw head. The first and second retaining lugs are, for example, arranged axially and tangentially offset from each other.
[0049] Preferably, the door component is pre-assembled at the mounting opening of the assembly carrier by means of the mounting clip. Additionally or alternatively, a mounting screw is preferably pre-assembled in the mounting clip, particularly in the retaining sleeve, in the pre-assembly position. In the pre-assembly position, for example, the screw head of the mounting screw is axially positively locked between the first and second retaining lugs, with the shank of the mounting screw being at least partially engaged in the through-opening of the sleeve body, and thus in the mounting openings of the assembly carrier and / or the door component.
[0050] The fastening clip described above is inventive in itself and thus constitutes an original invention. In particular, the fastening clip can also be used for pre-assembling door components onto the assembly carrier, provided these components do not protrude beyond the outer edge of the assembly carrier. The fastening clip can also be designed, independently of any door component, solely for pre-assembling the fastening screw.
[0051] The door module according to the invention is designed, suitable, and configured for a door assembly as described above. The door module comprises a mounting bracket and a door component pre-mounted thereon, with an edge-side component overhang. The door module can be configured as a compact module, a standard module, or a structural module.
[0052] The vehicle door according to the invention is particularly designed as a side door for a motor vehicle. The vehicle door comprises a door assembly as described above. The door assembly, or rather the Y-shaped mounting of the door module that can be implemented according to the invention, results in a vehicle door that is particularly easy to install.
[0053] An embodiment of the invention is explained in more detail below with reference to a drawing. The drawing shows: Fig. 1. In perspective view, a section of a door module with an aggregate carrier, a plate element, and a door component. Fig. 2.

[0054] Corresponding parts and sizes are always marked with the same reference symbols in all figures.
[0055] The Fig. 1 and Fig. Figure 2 shows a door module 2 for a door assembly 4 of a vehicle door 6 ( Fig. 10). The vehicle door 6 is designed in particular as a side door of a motor vehicle.
[0056] The following information regarding spatial directions is also given in a vehicle coordinate system (vehicle coordinate system) with respect to the side door. The abscissa (X-axis, X-direction) is oriented along the vehicle's longitudinal direction (direction of travel), the ordinate (Y-axis, Y-direction) along the vehicle's transverse direction, and the application axis (Z-axis, Z-direction) along the vehicle's height.
[0057] The door module 2 has an aggregate carrier 8 arranged essentially in the XZ plane, which is mounted as a wet / dry compartment divider for the door assembly 4. The aggregate carrier 8 thus has a dry compartment side 10 facing the vehicle interior and a wet compartment side 12 facing the vehicle environment ( Fig. 9) on.
[0058] The door module 2 has a panel element 14 pre-mounted on the dry room side 10, which projects beyond an outer circumference or outer edge 16 of the aggregate carrier 8, particularly in the X direction. The panel element 14 is designed as follows: Fig. 1 to Fig. 10 is attached to the aggregate carrier 8 by means of two fastening screws 18.
[0059] The plate element 14, which is approximately L-shaped in the YZ plane, is fixed to the dry room side 10 at the free end of the long leg of the L by means of the fastening screws 18. The short leg of the L is oriented approximately in the Y direction towards the wet room side 12 and extends upwards towards the wet room side 12 in the Y direction. The short leg of the L thus encompasses at least part of the aggregate carrier 8.
[0060] As particularly evident in the semi-transparent representation of the Fig. As can be seen in Figure 2, a door lock is pre-mounted as a door component 20 on the inside of the L-shaped plate element 14. The plate element 14, designed as a lock plate, has a recess for the lock jaw 22, which extends over the corner area of the L-legs. The door lock 20 is fixed to the shorter L-leg by means of three screw elements 24.
[0061] The Fig. Figure 3 shows an inner door part 26 of a standard door assembly. The inner door part 26 has a central mounting opening 28 for the door module 2 or the assembly carrier 8. Furthermore, the inner door part 26 has the lock jaw 22 and the recesses for the screw elements 24 for attaching the door lock 20. The door lock 20 has a component projection in the X-direction to be fixed to the door frame. Therefore, to mount the door module to the door frame, either a pivoting and folding movement is necessary, or the projecting door component is only moved into its final position (pivoted, folded, or shifted) after the module has been mounted to the door frame.
[0062] Fig. Figure 4 shows an inner door part 26 according to the invention for mounting the in Fig. 1 and Fig. 2 door module 2 shown. In contrast to the prior art, the inner door part 26 in the area of the door lock 20 has a receptacle 30 open in the Y direction in the form of a recess or indentation brought in along the Y direction.
[0063] As in the Fig. 5 and Fig. As shown in Figure 6, the door module 2 is mounted in the Y direction onto the inner door part 26, so that the door lock 20, which is held in a cantilever-like manner on the plate element 14, is arranged in the receptacle 30. The plate element 14 rests at its edge against a support surface surrounding the receptacle 30, and is screwed to the inner door part 26 in the area of the short L-leg as a reinforcing plate.
[0064] As in Fig. As shown in Figure 7, the mounting of the door lock 20 on the plate element 14 ensures that a sealing element 32, running around the entire perimeter of the aggregate carrier 8 on the wet room side, is not interrupted in the area of the door lock 20. The sealing element 32 is, for example, designed as a foam seal (sealing bead) along the outer edge 16.
[0065] As in Fig. As shown in Figure 8, a closed profile of the door assembly 4 is thus made possible, in which the door lock 20 is accommodated. This results in a particularly stable door assembly 4. Fig. Figure 9 shows a section view along the section line IX-IX of the Fig. 8 through the closed profile made of panel element 14 and the inner part of the door 26 of the door shell.
[0066] The Fig. Figure 10 shows a section of the lock area of the vehicle door 6 with the door assembly 4 and an interior trim panel 34 as well as a body seal 36.
[0067] The following is based on the Fig. 11 to 17 explain an alternative fastening or pre-assembly of the door component 20 or the panel element 14 on the aggregate carrier 8.
[0068] The assembly carrier 8 has two hole-like mounting openings 38 that completely penetrate the assembly carrier 8 as through-holes. The mounting openings 38 are designed, for example, as screw points. The plate element 14 has corresponding mounting openings 40. In contrast to the embodiment described above, no mounting screw 18 is inserted into the mounting openings 38, 40, but rather a mounting clip 42 in each case. The mounting clip 42 secures the plate element 14 to the assembly carrier 8 by means of a positive and / or non-positive locking connection. The plate element 14 – and thus the door component or the door lock 20 – is therefore pre-assembled and fastened to the assembly carrier 8 without mounting screws 18.
[0069] The fastening clip 42 is designed and configured to pre-assemble the plate element 14 on the aggregate carrier 8, i.e., to pre-position it and fix it in such a pre-assembly or delivery position ( Fig. 15) The fastening clip 42 thus provides, in particular, a preliminary positioning or arrangement of the plate element 14 on the assembly carrier 8, which takes place before final assembly in order to facilitate the assembly processes. Preferably, for final assembly, a fastening screw 18 is guided through the fastening clip 42, so that by screwing the assembly carrier 8 to the door frame or inner door part 26, the plate element 14 is finally fixed in its position on the assembly carrier 8, and can thus also fulfill structural functions ( Fig. 17).
[0070] The in Fig. The fastening clip 42, shown in Figure 14, has a cuff-like sleeve body 44 with a central through-hole 46 for the passage of a screw shank 48 of the fastening screw 18. The sleeve body 44 defines an axial direction A and a radial direction R of the fastening clip 42, wherein the axial direction A is oriented parallel to the transverse direction Y of the vehicle, i.e., perpendicular to the component carrier 8, in the assembly state. The sleeve body 44 has an outer circumference which essentially corresponds to the inner circumference of the fastening openings 38, 40, so that the sleeve body 44 can be inserted radially into the fastening openings 38, 40 in a form-fitting manner during pre-assembly or clipping.
[0071] The sleeve body 44 has a flange collar 50 molded onto its end face, in particular in one piece, i.e., as a single unit or monolithic, as a contact surface for a screw head 51 of the fastening screw 18 ( Fig. 17) The flange collar 50 is integrally formed on an end face of the sleeve body 44 facing the dry room side 10 in the assembly state, and is radially widened with respect to the outer circumference of the sleeve body 44. In particular, the outer diameter of the flange collar 50 is dimensioned larger than the inner diameter of the fastening openings 38, 40, so that the flange collar 50 acts as an axial stop or limit of the clipping in the clipped state.
[0072] In the illustrated embodiment, the sleeve body 44 is designed as a segmented ring wall with three ring wall sections 52, wherein a locking tab 54 for clip fastening is arranged between each pair of adjacent ring wall sections 52. The sleeve body 44 thus has three tangentially evenly distributed locking tabs 54.
[0073] Starting from the flange collar 50, the locking tabs 54 preferably extend over the entire axial length of the sleeve body 44 and project axially upwards at its end face.
[0074] The locking tabs 54 are radially flexible due to the clearances to the ring wall sections 52, and each has a locking lug 56 on the free end for positive and / or force-fit clip fastening. In the clipped state, the locking lug 56 engages behind a wet-room-side opening edge of the mounting opening 38 of the aggregate carrier 8 ( Fig. 13, Fig. 15).
[0075] For clipping, the fastening clip 42 is inserted, for example, from the dry room side 10, together with the sleeve body 44, into the fastening openings 40, 38 of the door component 20 and the aggregate carrier 8. The radially outwardly directed locking lugs 56 have an axially extending wedge shape, so that when the sleeve body 44 is inserted, the locking lugs 56 slide along the opening edge of the fastening opening 40 of the plate element 14, thereby deflecting the locking tabs 54 radially inwards.
[0076] The resulting mechanical preload causes the locking tab 54 to move radially outwards automatically after passing through the fastening openings 40, 38, so that the locking lugs 56 engage radially behind the opening edge of the fastening opening 38 and thus clip into place.
[0077] For example, in the sectional view of the Fig. As can be seen in Figure 15, the plate element 14 and the aggregate carrier 8 are thus axially positively fixed in the clipped state between the flange collar 50 and the locking lugs 56. Furthermore, the ring wall sections 52, which are seated in the mounting openings 38, 40, provide a radial positive fit through the clipping.
[0078] For example, on the wet room side 12 of the aggregate carrier 8, three locking receptacles 58 are provided, into which the locking lugs 56 can be tangentially engaged in a form-fitting manner. This ensures that the fastening clip 42 is also tangentially fixed in a form-fitting manner when clipped in.
[0079] By using the fastening clip 42, it is possible to pre-position or fasten (stiffening) elements, such as the plate element 14, on the aggregate carrier 8 without undercutting.
[0080] As for example in the enlarged view of the Fig. As can be seen in Figure 16, the sleeve body 44 or the ring wall sections 52 and locking tabs 54 have a radial clearance 60 with respect to the fastening openings 38, 40 for a tolerance compensation of the plate element 14 to the aggregate carrier 8.
[0081] The Fig. Figure 15 shows a pre-assembled or delivery state in which the plate element 14 – and thus the door lock 20 – is clipped to the aggregate carrier 8 by means of the fastening clip 42. Fig. Figure 17 shows a corresponding final assembly state in which the fastening screw 18 is guided through the through-hole 46 of the fastening clip 42 by means of the screw shaft 48 and is screwed into a (threaded) nut 62 on the inner part of the door 26.
[0082] The following is based on the Fig. A second embodiment of the fastening clip 42 is explained in more detail in sections 18 to 24.
[0083] In this embodiment, a retaining sleeve 64, which in the assembled state protrudes upwards on the dry-room side, is formed as an annular collar for receiving and holding a fastening screw 18. The circumferentially closed retaining sleeve 64 is aligned coaxially with the sleeve body 44.
[0084] The retaining sleeve 64 and the sleeve body 44 are integrally formed on opposite flat sides of the approximately annular flange collar 50, wherein the sleeve body 44 encloses a radially inner annular opening as the opening of the central through-hole 46, and wherein the retaining sleeve 64 is arranged circumferentially on an outer radius of the flange collar 50.
[0085] The retaining sleeve 64 has a number of radially inwardly projecting retaining lugs 66, 68 for axially retaining the fastening screw 18, in particular the screw head 51, in a pre-assembly position V. The screw head 51 has a radially widened fastening collar 70, which is axially positively locked in place by the retaining lugs 66, 68 in the pre-assembly state.
[0086] The retaining lugs 66, 68 are in particular one-piece, i.e. monolithic, formed on the inner circumference of the retaining sleeve 64.
[0087] In the illustrated embodiment, the retaining sleeve 64 has three wedge-shaped retaining lugs 66 as axial supports for the screw head 51 or the fastening collar 70, which are arranged tangentially around the inner circumference of the retaining sleeve 64. The inner diameter of the retaining sleeve 64 corresponds essentially to the outer diameter of the fastening collar 70, so that the radially inwardly projecting retaining lugs 64 act as axial supports for the fastening collar 70.
[0088] The supports for the fastening collar 70 are, for example, axially inclined radially inwards, so that when axial pressure is applied to the fastening screw 18, the fastening collar 70 slides axially on the supports.
[0089] In the illustrated embodiment, the retaining sleeve 64 further comprises three wedge-shaped retaining lugs 68 for axial securing of the screw head 51 or the mounting collar 70. The retaining lugs 68 are arranged tangentially offset from the retaining lugs 64 and are positioned axially outwards relative to the retaining lugs 66 with respect to the flange collar 50. The retaining lugs 68 engage the mounting collar 70 radially when the latter rests on the retaining lugs 66. This ensures that the mounting collar 70 – and thus the fastening screw 18 – is axially positively locked in place by the retaining lugs 66, 68 in the pre-assembly position V.
[0090] The retaining lugs 66, 68 are arranged axially on the retaining sleeve 64 such that the fastening screw 18, in the pre-assembly position V, engages with the screw shank 48 in the feedthrough opening 46. Preferably, the fastening screw 18 is positioned in the pre-assembly position V such that the locking tabs 54 on the end face of the screw shank 48 protrude at least partially axially upwards ( Fig. 23).
[0091] For pre-assembly of the fastening screw 18, it is inserted into the retaining sleeve 64 via the screw shank 48. The screw shank 48 is moved into the through-hole 46, and the fastening screw 18 is lowered axially until the fastening collar 70 rests against the wedge surfaces of the retaining lugs 68. The retaining lugs 66, 68 are at least partially axially and / or radially flexible, so that when the fastening screw is pressed in axially, the retaining lugs 68 are deformed, particularly elastically, causing the fastening collar 70 to come to rest on the retaining lugs 66, and the retaining lugs 68 to return to their initial position.
[0092] To insert the fastening screw 18 into the Fig. To move the screw head 51 from the pre-assembly position V shown in Figure 24 to the final assembly position E, it is pressed axially towards the flange collar 50. This elastically deforms the retaining lugs 68 until the fastening collar 70 is released and the axial positive locking of the retaining lugs 66, 68 is broken. The fastening screw 18 is then screwed to the door frame or the inner door part 26.
[0093] The fastening clip 42 of the Fig. The components 18 to 24 enable the pre-positioning of fastening screws 18 or other fastening elements on the door module 2 or on the assembly carrier 8, so that fastening screws 18 or other fastening elements can be delivered pre-assembled to the OEM at the assembly line. With a suitable design of the fastening clip 42, it is conceivable that only the fastening screws 18 on the door module 2 or assembly carrier 8 need to be pre-positioned.
[0094] The claimed invention is not limited to the embodiment described above. Rather, other variants of the invention can also be derived by a person skilled in the art within the scope of the disclosed claims without departing from the subject matter of the claimed invention. In particular, all individual features described in connection with the embodiment can also be combined in other ways within the scope of the disclosed claims without departing from the subject matter of the claimed invention.
[0095] Thus, the fastening clip 42 is inventive on its own or in combination with a door module, and therefore also represents an invention in its own right, independent of the door component 20 or the panel element 14.
