Abstract
Description
FIELD OF THE INVENTION
[0001] The present invention relates to the fastening of components in a vehicle door or other movable closure component. In particular, the present invention relates to a fastening device for a locking device of a movable closure component, to a motor vehicle lock module, to a motor vehicle door module, and to a method for assembling a locking device of a movable closure component. BACKGROUND OF THE INVENTION
[0002] A variety of components are used in vehicle doors, such as window regulators, door locks, and various drives. Drives include, for example, closing aids that are held on a supporting structure of a vehicle door, such as a door panel or a multifunctional bracket attached to the door panel. Mounting buffers can be used for this purpose, for example to absorb structure-borne noise generated by the drive, e.g. the closing aid, so that it is transmitted into the vehicle structure to the smallest possible extent. EP 3098372 A1, for example, describes a fastening element with a vibration-damping effect. However, it has become apparent that there is a need for further improvement, due, for example, to increased user demands. SUMMARY OF THE INVENTION
[0003] An object of the present invention is therefore to provide a fastening for locking devices in vehicle doors which transmits as few vibrations as possible.
[0004] This object is achieved by the subject matter of the independent claims. Further examples are specified in the dependent claims. The aspects described below also apply to the fastening device for a locking device of a movable closure component, to the motor vehicle lock module, to the motor vehicle door module, and to the method for assembling a locking device of a movable closure component, and vice versa. Furthermore, even those features for which this is not explicitly mentioned can be freely combined with one another.
[0005] According to the invention, a fastening device for a locking device of a movable closure component is provided. The fastening device has a first fastening region for holding the locking device, a second fastening region for securing it to a supporting structure of the vehicle door, and a connecting region between the first and second fastening regions, which extends along a fastening axis. The connecting region transmits a holding force from the first fastening region to the second fastening region. The first fastening region or the second fastening region, or both, are designed as a vibration-damping fastening region and are made of an elastic material. The elastic material has a first vibration-damping property.The connecting area has a second vibration-damping property that differs from the first vibration-damping property. The connecting area also has a spring element that transmits the holding force.
[0006] The fastening device therefore provides a holder or mounting for a locking device on a vehicle door that also dampens vibrations. The locking device is therefore dampened. The locking device is, for example, a drive or similar; vibrations are regularly generated during operation of the drive. To ensure that these are transmitted as little as possible, the fastening device is designed to dampen vibrations. In contrast to simple mounting on rubber buffers, the spectrum of vibration-damping properties is expanded through the additional use of a spring element, thus reducing the amount of vibration transmitted overall. Fewer transmitted vibrations lead to a reduction in the noise that is perceived as annoying when the locking device is in operation.
[0007] One advantage is that the at least one vibration-damping fastening area dampens higher frequencies, i.e. transmits them only in a weakened form, and that the connecting area dampens lower frequencies, i.e. transmits them only in a weakened form.
[0008] The spring element ensures that the holding position is maintained, both in the primary spring direction, i.e. in the direction of the fastening axis, and transversely to it, for example when the fastening axis is horizontal.
[0009] According to one example, the connection region is configured as a vibration-damping connection region. The at least one vibration-damping fastening region is configured for damping a first frequency range, and the vibration-damping connection region is configured for damping a second frequency range. The first frequency range has higher frequencies than the second frequency range.
[0010] According to one example, the spring element is designed as a helical spring which is held captively at one end on the first fastening region and at the other end on the second fastening region.
[0011] According to one example, the spring element has a first connection region for force introduction into the first fastening region, a second connection region for force introduction into the second fastening region, and a central winding region between the first connection region and the second connection region. At least one of the group comprising the first connection region and the second connection region has a force-transmitting end region running transversely to the fastening axis and an axial transition region extending between the central winding region and parallel to the fastening axis.
[0012] The axial transition area allows penetration into a holding area with minimal entry area. The design of the transverse area for force transmission provides maximum grip.
[0013] According to one example, the spring element with the axial transition area projects into the respective fastening area.
[0014] According to one example, the force transmission end region extending transversely to the fastening axis extends perpendicular to the fastening axis. The force transmission end region is embedded in the fastening region.
[0015] As an option, the force transmission end area is provided with an extension that runs in one plane in the fastening area.
[0016] According to one example, the axial transition region is centered along the fastening axis.
[0017] According to one example, the central winding region is formed around a winding axis. The axial transition region extends coaxially to the winding axis.
[0018] According to one example, the at least one vibration-damping fastening region has a soft component.
[0019] According to one example, a hard component is provided at each of the first fastening region and the second fastening region, on which the spring element, for example, the coil spring, is held. The hard component is connected to the soft component.
[0020] According to one example, the connecting region has a travel limiter parallel to the fastening axis, which limits a possible change in length of the connecting region in at least one direction.
[0021] According to one example, at least one of the two fastening regions has a retaining groove for engaging an edge segment of a fastening opening on the closure device or the supporting structure. At least one of the two fastening regions is designed as a pull-through plug, which has an extension at the free end for applying a tensile force when inserting the fastening device into the fastening opening provided as a retaining hole.
[0022] According to one example, the first and second fastening areas are identical in their connection geometry.
[0023] According to one example, at least one of the group comprising the first and the second fastening region is each rotationally symmetrical about an axis aligned with the fastening axis.
[0024] According to the invention, a motor vehicle lock module is also provided, which has a locking device for a movable closing component and at least one fastening device according to one of the previous examples. The at least one fastening device is provided to fasten the locking device to a supporting structure. The locking device is designed as one of the group of door lock drive, pull assist drive and erection drive.
[0025] According to the invention, a motor vehicle door module is also provided, which has a supporting structure of a motor vehicle door and at least one motor vehicle lock module according to the previous example. The at least one motor vehicle lock module is held on the supporting structure.
[0026] According to the invention, a method for assembling a locking device of a movable closing component is also provided. The method comprises the following steps: - Attaching at least one fastening device according to one of the preceding examples to the locking device; one of the two fastening areas is inserted into a receptacle on the locking device; - positioning the locking device in relation to a supporting structure of the movable closure component; and - Inserting the other of the two fastening areas into a socket on the supporting structure.
[0027] In an alternative variant, one of the two fastening areas of the at least one fastening device is first inserted into a receptacle on a supporting structure of the movable closure component. A locking device is then positioned relative to the supporting structure, and the other of the two fastening areas is subsequently inserted into a receptacle on the locking device.
[0028] According to one aspect, a fastening device is provided in which several damping elements are combined. For example, the advantages of buffers made of elastomers and the buffering properties of metallic springs are combined. Elastomers have good buffering properties for vibrations above 500 Hz, and metallic springs in the range from 100 Hz to 500 Hz. By combining both elements, a larger frequency range can be damped. In one example, a buffer made of a soft plastic component is combined with a metallic compression spring. For example, in addition to the soft plastic component, another hard plastic component is used in the buffer, to which the compression spring is molded.
[0029] According to one aspect, a mounting buffer for components in vehicle doors is provided, in which two different damping areas are combined to achieve an expanded damping spectrum or improved damping for reduced vibration transmission. For this purpose, a spring element is combined with soft rubber areas for insertion into receptacles. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Fig. 1 shows a fastening device 10 for a locking device of a movable closure component. The fastening device 10 has a first fastening region 12 for holding the locking device (not shown), a second fastening region 14 for securing it to a supporting structure of the vehicle door (not shown), and a connecting region 16 between the first fastening region 12 and the second fastening region 14. The connecting region 16 extends along a fastening axis 20. The connecting region 16 transmits a holding force from the first fastening region 12 to the second fastening region 14. At least one of the group comprising the first fastening region 12 and the second fastening region 14 is designed as at least one vibration-damping fastening region and is made of an elastic material.The elastic material has a first vibration-damping property, and the connecting region 16 has a second vibration-damping property that differs from the first vibration-damping property. The connecting region 16 has a spring element 18 that transmits the holding force.
[0032] In one option, both fastening areas, i.e. the first and the second fastening area, are each designed as a vibration-damping fastening area.
[0033] The term “fastening device” refers to a component with which the locking device can be fastened, i.e. held permanently. The fastening device 10 serves to transmit the holding force so that the locking device is mounted on a supporting structure. The fastening device 10 is directly responsible for the force transmission. In this case, several fastening devices 10 can be provided for one locking device, for example two, preferably three or more, for example three, four, five or more fastening devices 10, in order to hold the locking device securely. The holding can be detachable or non-detachable. Detachable means that the fastening device 10 can be released again, i.e. dismantled and then reassembled. For example, the fastening device 10 can be inserted into an opening or receptacle and removed from there again.Indetachable means that the fastening device 10 can only be removed by destroying or at least damaging the fastening device 10 and can then no longer be used.
[0034] The term “movable closure component” refers to a movable component on a motor vehicle with which an opening or access can be temporarily closed by closing the movable closure component and with which the opening or access can be temporarily made accessible by opening the movable closure component. The term “movable closure component” therefore refers to a movable closure of a motor vehicle. The movable closure component is, for example, a motor vehicle door, a motor vehicle flap, a motor vehicle hood or a loading flap. The movable closure component comprises at least one from the group comprising motor vehicle doors, motor vehicle flaps, motor vehicle hoods or loading flaps. Motor vehicle doors can, for example, be doors that swing open to the side, or sliding doors or even doors or door segments that swing open upwards.Motor vehicle flaps can be, for example, tailgates. Motor vehicle hoods can be, for example, engine compartment hoods, for example in the front area of the vehicle. Motor vehicle hoods can also be front hoods for closing off storage areas underneath. These front hoods are also referred to as frunks (from the English: front trunk). Loading flaps can be, for example, pivoting flaps provided at the rear or on the side to allow access to a loading area or a loading area. The loading flaps can also be referred to as motor vehicle loading flaps. In connection with so-called pick-up trucks, e.g. with an open loading area, the loading flaps are also referred to as drop gates. When motor vehicle doors are mentioned in the context of the present invention, this also includes the other forms of the movable closing component mentioned as examples.The term door lock includes, for example, a lock for a motor vehicle door, a lock for a motor vehicle hatch, a lock for a motor vehicle hood or a lock for a tailgate.
[0035] The term “locking device” refers, for example, to mechanical assemblies for locking or moving a movable vehicle component.
[0036] For example, the locking device is a door lock, a door lock drive or a door drive.
[0037] The term "door lock" refers to a lock on a vehicle door. A door lock, for example, releasably holds a striker or locking bolt to keep a door closed.
[0038] The term "door lock drive" refers to a drive for the locking mechanism of a door lock. A door lock drive is, for example, an electric drive for opening the locking mechanism of a door lock. The door lock drive can also be designed as an electric drive for closing the rotary latch of a vehicle lock to close a door. The door lock drive is designed, for example, as a closing aid.
[0039] The term “door drive” refers to a drive for moving the vehicle door, for example to at least partially open or close the door. The door drive is, for example, a door stay, also known as a door presenter or push-out unit, with which the door is opened ajar. The door drive is, for example, a drive for completely opening a movable closing component, for example a tailgate. The door drive is, for example, a closing aid with which the door, i.e. the movable closing component, is pulled into the closed position, for example against the sealing pressure of the door seal. The door drive is, for example, designed as a door stay, which pushes the door away from a vehicle body in order to open the door ajar. The door drive can also act as a drive on a door check in order to move the door in relation to the body.
[0040] The term “fastening area” refers to the area or part of the fastening device 10 which is intended for the actual fastening, i.e. the hold on the locking device or the supporting structure.
[0041] The term “connecting area” refers to the area or part between the two fastening areas 12, 14. The connecting area 16 serves to transfer the holding force from one fastening area to the other fastening area.
[0042] The fastening device 10 is, for example, elongated and has a fastening area 12, 14 at both ends. The fastening areas 12, 14 serve to initiate or transmit the holding force.
[0043] The term "elastic material" refers to a soft, i.e., flexible, yet dimensionally stable material. An elastic material is, for example, a rubber or an elastomer. The elastic material provides vibration damping primarily due to its material properties.
[0044] The term "spring element" refers to a component that has a resilient, i.e., compliant, shape. The spring element 18 provides vibration damping primarily due to its geometric deformability.
[0045] Optionally, the connection region 16 is configured as a vibration-damping connection region. The at least one vibration-damping fastening region is configured for damping a first frequency range, and the vibration-damping connection region is configured for damping a second frequency range. The first frequency range has higher frequencies than the second frequency range.
[0046] By dampening a wider frequency range, better absorption of structure-borne noise can be achieved, resulting in less noise that is disturbing to the user.
[0047] In one option, both fastening areas 12, 14 are designed as vibration-damping fastening areas.
[0048] In a further option, one vibration-damping mounting region is configured for damping a first frequency range, and the other vibration-damping mounting region is configured for damping a further frequency range, for example, a second frequency range. The vibration-damping connection region is then configured for damping a still further frequency range, for example, a third frequency range.
[0049] The frequency range(s) of the two fastening areas 12, 14 can also be referred to as the primary frequency range(s). The frequency range of the connecting area 16 can also be referred to as the secondary frequency range.
[0050] Fig. 2a shows another example of the fastening device 10. For example, the spring element 18 is designed as a helical spring 22, as in Fig. 1. The coil spring 22 is captively held at one end to the first fastening region 12 and at the other end to the second fastening region 14.
[0051] The spring element 18 can also be designed, for example, as a torsion spring, conical spring, double spring, helical spring, spiral spring, bellows, pin with one or more disc springs or made of foam.
[0052] The double spring, for example, has two springs arranged inside each other.
[0053] In the example shown, the coil spring has a round cross-section. For example, the spring is made of a round, e.g., circular or oval profile.
[0054] In another example, the coil spring has a square cross-section. For example, the spring is made from a rectangular, e.g., square, profile.
[0055] In one option, the spring element 18 is provided with different stiffnesses, i.e. different spring forces, along the possible elastic deformation.
[0056] Fig. 2b shows the fastening device 10 from Fig. 2a in a sectional view.
[0057] As an option, it is shown that the at least one vibration-damping fastening region has a soft component 24. For example, the soft component is a soft rubber.
[0058] As a further option, it is shown that a hard component 26 is provided on each of the first fastening region 12 and the second fastening region 14, to which the spring element 18, for example, the helical spring 22, is held. The hard component 26 is connected to the soft component 24.
[0059] In one example, the coil spring 22 is held with a free end region of the spring coils embedded in the hard component 26. For example, the coil spring 22 is held captively at the respective fastening area by means of injection molding or overmolding.
[0060] For example, the coil spring 22 has two coils at the beginning and / or end that lie against each other.
[0061] In one example, the hard component 26 is held on the soft component 24 or connected to it by partial overmolding with the soft component 24.
[0062] As a further option, it is shown that at least one of the two fastening areas 12, 14 has a retaining groove 28 for engaging an edge segment 30 of a fastening opening on the locking device or the supporting structure.
[0063] For example, one fastening opening is provided in a housing 30a of the locking device (not shown). For example, the other fastening opening is provided in a supporting plate 30b of the locking device (not shown). The housing 30a and the supporting plate 30b are shown in dashed lines.
[0064] As an option, it is shown that at least one of the two fastening areas 12, 14 is designed as a pull-through plug 32, which has an extension 34 at the free end. This serves to apply a tensile force when inserting the fastening device 10 into the fastening opening provided as a holding hole.
[0065] The term "pull-through plug" refers to a configuration of the ends of the fastener that are designed to be inserted into mounting holes or other receptacles by pulling the end. With the pull-through plug or pull-through end, only the end is pulled into the mounting hole, not the entire fastener.
[0066] In one variant, both fastening areas 12, 14 are formed with a retaining groove. Instead of a retaining groove, a projection can also be formed that protrudes laterally and, once pulled through an opening, forms a kind of rear grip and secures the fastening device.
[0067] In one variant, only one of the two fastening areas 12, 14 is designed as a pull-through plug 32. In another variant, both fastening areas 12, 14 are designed as pull-through plugs 32. In an alternative variant, neither of the two fastening areas 12, 14 is designed as a pull-through plug.
[0068] The pull-through plugs 32 can also be referred to as pull-through ends of the mounting buffer.
[0069] In one option, the first and second fastening areas 12, 14 are designed identically in their connection geometry.
[0070] The term “equal” refers to a design of the connections that is so similar that it allows for installation in any direction, which simplifies assembly.
[0071] For example, the first and second fastening areas 12, 14 are formed symmetrically, for example mirrored transversely to the fastening axis.
[0072] In an alternative embodiment, the two fastening areas 12, 14 are so different in their connection geometry that confusion can be excluded and thus a fixed installation direction is guaranteed.
[0073] In one option, the first fastening area 12 or the second fastening area 14 or both fastening areas 12, 14 are each rotationally symmetrical about an axis aligned with the fastening axis 20.
[0074] The fastening device 10 can, for example, be installed independently of rotation.
[0075] For example, the first and second fastening regions 12, 14 are rotationally symmetrical.
[0076] For example, the fastening device 10 is formed in one piece.
[0077] The one-piece design provides that the individual components and areas are connected to one another in a captive manner, so that both storage and handling and assembly of the fastening device 10 are simplified.
[0078] In an example not shown in detail, the spring element 18 has a coil region with a first and a second end. The coil region engages with the first fastening region at the first end and with the second fastening region at the second end. The coil region extends a short distance into the first and second fastening regions, for example, half or one whole or more coils of the coil spring.
[0079] Fig. 3a shows a side view of another example of a fastening device. The spring element 18 has a first connection region 52 for introducing force into the first fastening region 12, and a second connection region 54 for introducing force into the second fastening region 14. The spring element 18 also has a central winding region 56 between the first connection region 52 and the second connection region 54. At least one of the group comprising the first connection region 52 and the second connection region 54 has a force-transmitting end region 58 running transversely to the fastening axis, and an axial transition region 60 extending between the central winding region 56 parallel to a fastening axis 59.
[0080] The spring element 18 has, for example, a spiral winding region 61.
[0081] Fig. 3b shows the example from Fig. 3a in a perspective view.
[0082] The force transmission end region 58, which runs transversely to the fastening axis, transmits the holding force into the fastening region with a type of positive locking, for example by embedding the force transmission end region in plastic or another suitable material.
[0083] In an alternative example, at least one of the group comprising the first connection region 52 and the second connection region 54 has an axial transition region 60 extending between the central winding region 56 parallel to the spring axis 62.
[0084] Fig. 4 shows the spring element 18 of the example from Fig. 3b in an isolated perspective view, without the first fastening area 12 and without the second fastening area 14.
[0085] In one example, the first connection region 52 has a first force-transmitting end region extending transversely to the fastening axis, and a first axial transition region extending between the central winding region and parallel to the fastening axis. Optionally, the second connection region is configured as a continuation of the winding region. The second connection region can also be shaped differently.
[0086] In another example, the second connection region has a second force-transmitting end region extending transversely to the fastening axis, and a second axial transition region extending between the central winding region and parallel to the fastening axis. Optionally, the first connection region is configured as a continuation of the winding region. The first connection region can also be shaped differently.
[0087] In one example, the first connection region has a first force-transmitting end region running transversely to the fastening axis, and a first axial transition region extending between the central winding region and parallel to the fastening axis. The second connection region has a second force-transmitting end region running transversely to the fastening axis and a second axial transition region extending between the central winding region and parallel to the fastening axis.
[0088] The spring element 18 extends into the fastening area 12, 14 in the axial direction with the connection area 52, 54, and the connection area is then deformed within the fastening area transversely to the axial direction, e.g., vertically. To achieve the best possible force transmission, the connection area has a curvature, e.g., a semicircle, a three-quarter circle, or more. The connection area can also have an angled orientation transversely to the axial direction.
[0089] The spring element 18, for example, has, following the windings, a web region 64 extending radially to the axis, which then merges into an axial part extending in the axial direction, i.e., the extending axial transition region 60, which projects into the plastic. This is followed by a further web region 66 extending radially to the axis, which then in turn merges into a transversely extending holding part, i.e., the force transmission end region 58 running transversely to the fastening axis.
[0090] In one option, as shown, it is provided that the spring element 18 projects with the axial transition area into the respective fastening area.
[0091] The axial transition region 60 has an exposed part which transitions into the central winding region and a part embedded in the fastening region.
[0092] In one example, the spring element 18 projects with the first axial transition region into the first fastening region, and with the second axial transition region into the second fastening region.
[0093] In one example, the force transmission end region 58, which runs transversely to the fastening axis, extends perpendicular to the fastening axis 62. The force transmission end region is embedded in the fastening region. Optionally, the force transmission end region may have an extension that runs in a plane within the fastening region.
[0094] In one example, the extension has a round outline, i.e., a round shape. In another example, the extension has an angular outline, i.e., a shape. In another example, the extension has a triangular outline, i.e., a triangular shape.
[0095] In one example, the first force-transmitting end region, which runs transversely to the fastening axis, extends perpendicularly to the fastening axis, and the second force-transmitting end region, which also runs transversely to the fastening axis, also extends perpendicularly to the fastening axis. The first and second force-transmitting end regions are each embedded in the fastening region.
[0096] In another example, the first force transmission end region extending transversely to the fastening axis extends perpendicular to the fastening axis, and the second force transmission end region extends deviatingly.
[0097] In yet another example, the second force transmission end region extending transversely to the fastening axis extends perpendicular to the fastening axis, and the first force transmission end region extends deviatingly.
[0098] According to one example, the axial transition region is centered along the fastening axis.
[0099] According to one example, the central winding region is formed around the winding axis 62. The axial transition region extends coaxially to the winding axis.
[0100] This enables, for example, spring neutrality around the longitudinal axis of the fastening device.
[0101] Fig. Figure 5 shows yet another example of a fastening device in a side view. A hard component 66 is provided on each of the first fastening region 12 and the second fastening region 14, to which the spring element 18 is held. The hard component is connected to the soft component.
[0102] In one example, a first hard component is provided on the first fastening region 12, to which the spring element 18 is held. The hard component is connected to the soft component. Another fastening is provided on the second fastening region 14.
[0103] In another example, a second hard component is provided on the second fastening region 14, on which the spring element 18 is held. The hard component is connected to the soft component. Another fastening is provided on the first fastening region 12.
[0104] In another example, a first hard component is provided on the first fastening region 12, on which the spring element 18 is held and which is connected to the soft component. Furthermore, a second hard component is also provided on the second fastening region 14, on which the spring element 18 is held and which is connected to the soft component.
[0105] As an option, it is provided that the hard component is designed as an insert in a softer plastic and that the widening of the first and / or the second connection area is provided in the insert.
[0106] Fig. 6 shows a further example of the fastening device 10. The connecting region 16 has a travel limiter 36 parallel to the fastening axis, which limits a possible change in length of the connecting region 16 in at least one direction.
[0107] The term "travel limiter" refers to a component that restricts, i.e., limits, a possible deformation of the fastening device 10. The travel limiter 36 has no or only a minimal influence on the vibration-damping properties for the unrestricted range of deformation of the fastening device 10.
[0108] As an option, the travel limiter 36 is provided to limit a possible change in length of the connecting area 16 in only one direction, for example only in the tensile or only in the compressive direction.
[0109] As an option, Fig. 6, it is provided that the travel limiter 36 limits the change in length of the connecting area 16 only in the pulling direction.
[0110] As an example, the travel limiter 36 is in Fig. 6 as at least one tension element 38, which limits the change in length of the connecting region 16 in the tension direction to a maximum length L max limited. Two tension elements 38 are shown as an option. Only one or more than two tension elements 38 may be provided.
[0111] In an option not shown, a circumferential bellows-like cover is provided. The cover acts as the travel limiter 36 and also protects the spring element 18, keeping the travel area clear and preventing, for example, other components such as cables from getting between the spring coils.
[0112] The tension element 38 is, for example, a piece of rope, for example a rope loop, embedded in the two fastening areas 12, 14. In one example, the rope loop is flexible to prevent a hard impact.
[0113] In another option (not shown), it is provided that the travel limiter 36 limits the change in length of the connecting area 16 only in the pressure direction.
[0114] In a further option, the travel limiter 36 limits a possible change in length of the connecting area 16 in both directions, for example in the tensile and compressive directions.
[0115] The travel limiter 36 serves, for example, to ensure that the fastening device 10 does not expand too far, ie is not stretched too far, in the event of strong acceleration of the door in the direction of the fastening axis, for example when the vehicle door or tailgate is slammed shut, if, for example, the component to be fastened is arranged on a supporting structure on the side towards the interior.
[0116] Fig. 7a shows another example of the fastening device 10 with a second example of the integrated travel limiter 36.
[0117] The tension element here is designed in the form of two arms 40 extending toward one another, the two free ends 42 of which engage behind one another in the direction of tension to form a stop. For example, two pairs of arms are provided on opposite sides of the spring element. The engagement is designed, for example, so that the two ends are sufficiently spaced apart to prevent rattling during driving.
[0118] Fig. 7b shows the fastening device from Fig. 7a in a sectional view. The arms 40 are, for example, formed integrally with a hard component. The arms 40 can also be made of metal or another material and embedded at one end in the respective fastening area.
[0119] Fig. 8 schematically shows an example of a motor vehicle lock module 100. The motor vehicle lock module 100 has a locking device 102 for a movable closure component and at least one example of the fastening device 10 according to one of the preceding examples. The at least one fastening device 10 is provided to fasten the locking device 102 to a supporting structure (not shown). The locking device 102 is designed, for example, as a door lock drive, closing aid drive, or opening drive.
[0120] In the example, three fastening devices 10 are shown; however, more fastening devices 10 may be provided, for example four, five or more, or fewer.
[0121] In a further option (not shown), a support structure module is provided. The support structure module has a holding area for a locking device for a movable closure component and at least one example of the fastening device 10 according to one of the preceding examples. The at least one fastening device 10 is provided to fasten the locking device 102 to the support structure. The support structure is designed, for example, as a door structure, e.g., a door panel, or a multifunctional bracket.
[0122] Fig. 9 schematically shows an example of a motor vehicle door module 150 comprising a support structure 152 of a motor vehicle door and at least one example of the motor vehicle lock module 100 from Fig. 8. The at least one motor vehicle lock module 100 is held on the support structure 152. In Fig. 9, the support structure 152 is designed as a multifunctional bracket, also referred to as a multifunctional bracket (MFB). The motor vehicle lock module 100 is, for example, a drive, for example a closing aid or a multifunctional drive. The motor vehicle lock module 100 is connected to a door lock 156 and a door stay 158 via a force transmission means 154, for example a Bowden cable. The multifunctional bracket 152 is held on a door structure 160. Instead of the multifunctional bracket 152, the motor vehicle lock module 100 can also be attached to the door structure 160. The motor vehicle door is indicated by a window area 162 and two hinges.
