Description

Technical field

The invention relates to an inner door element for a motor vehicle door for positioning between the outer side of the door and the inner panel of the door.

BACKGROUND OF THE INVENTION

Such an inner door element, which is located in the door of a motor vehicle, forms the basis for a number of functional components and their fastening elements. This inner door element is usually made of sheet steel. Depending on the basic door concept, such interior door elements are then relatively heavy. In addition, there is a cost of sealing the passages in such interior door elements. In addition, interior door elements of plastic are known as a holder for motor vehicle door components. This results in a reduction in weight, but there is a problem with the acoustic function of these inner door elements, since neither a significant damping nor insulation is achieved. The known solutions are also not suitable as a barrier against moisture penetration. To compensate for these drawbacks, additional elements such as foils, damping foils and the like must be used.

SUMMARY OF THE INVENTION The object of the invention is to provide a structure of an inner door element which is simple to manufacture and which satisfies the other requirements imposed on such an inner door element.

SUMMARY OF THE INVENTION

This problem is solved and the drawbacks of known solutions of this kind are largely eliminated by the inner door element for a motor vehicle door for the location between the outer side of the door and the inner panel according to the invention. a sealing body positioned at the edge.

In addition, cable clamps are formed on this inner door element.

Further, a carrier ring can be formed on the inner door element for receiving the loudspeaker.

In addition, a cable gland can be formed on the inner door element.

The cable gland is preferably provided with a soft plastic peripheral lining.

The inner door element is preferably provided with a shaped casing.

Another advantageous embodiment of the inner door element is that the inner door element is provided with an intermediate carrier plate for mounting the motor.

Said support plate is preferably a metal plate.

Furthermore, it is advantageous if the inner door element is provided with injection molding bridges with freely accessible undersides.

A further advantageous embodiment of the inner door element is that the inner door element is provided in its wall with a recess for receiving the leaf insert.

Said sealing body is preferably formed by a caterpillar placed on the surface of the inner door element.

A preferred embodiment in this respect is that the sealing body is housed in an integrally formed groove of the inner door element.

Said groove is preferably formed by a curvature of the inner door element and a beaded thickening on the back of the inner door element.

The inner door element has different specific weights in its cross-section, i.e. it has a density of between 0.7 and 1.4 g / cm ³ in the unexpanded top layer and a density of 0.1 to 0.6 g / cm ³ in the expanded core.

The injection molding material of the inner door member preferably comprises a HMS (High Melt Strentgh) polymer component and fillers or reinforcing materials.

The inner door element is preferably provided at the front side of its perimeter with anchorage passages which are provided with integral shaping formed by massive linings.

It is further preferred that the anchoring passage is encircled from the front of the periphery by a projecting integrally formed lobe.

Advantageously, sleeves, threaded sleeves and the like are sprayed in the inner door element.

Furthermore, in the surface of the inner door element, its material is preferably partially removed or an impassable cut is made to provide access to its lower density.

The exposed core regions then serve as access to the anchoring means.

Finally, it is also advantageous if clips are fastened in the inner door element while maintaining the integral top layer.

The object of the invention is thus solved by an inner door element, in which a sealing body is placed on its edge by the foam injection molding method. As a result, an inner door element that is easy to manufacture and has high performance properties is obtained because it associates the function of the support and sealing body in a body with a significantly reduced weight. The possibility of better shaping is also achieved. The inner door element, which is substantially plate-shaped, comprises reinforcements in several directions, which contributes to its reinforcement. Another factor that increases the mechanical stability of the inner door element is the formation of a vitreous surface layer that occurs spontaneously in the foam injection molding process. In addition, the good damping and insulating properties of such an inner door element. In addition, in this design of the inner door element, an optimum handling of the transition to the door support structure, for example an inner door sheet in the shape that carries the inner door element, is achieved by virtue of the circumferential sealing member. Due to the design of the inner door element of the splashed foam, optimum conditions are also provided for gripping the sealing body which is anchored in the surface layer of the inner door element. It is an elastomer sealing body which is sprayed directly onto the inner door element and thus firmly gripped in the relatively thin surface layer of the inner door element. The temperature when spraying the elastomeric material of the sealing body is sufficient for the surface layer of the inner door element to soften and for the elastomeric material of the sealing body to be bonded flat to the inner door element without any joints. On the other hand, there is no damage to the inner door element. The sealing body may comprise a through cavity to improve its adhesion. This not only reduces the weight, but also saves material. Further details are evident from DE 295 1 1492 U and the European patent application no. 98 1 15 150.1. These documents form part of this application in their entirety, including in order to incorporate the features of these documents into the claims of this application. Furthermore, it has proved to be advantageous if cable clamps are formed on the inner door element. In this way, the previously used fasteners are replaced. It is furthermore proposed that a support ring is formed on the inner door element for receiving the loudspeaker. This support ring represents a reinforcement of the respective loudspeaker opening in the inner door element and a sufficiently strong base for fasteners, such as screws, and a sealing of the passage between the inner door element and the loudspeaker is also achieved. It has also proved to be advantageous if a cable gland is formed on the inner door element. In order to ensure tightness between the cable body and the cable gland, the cable gland is provided with a soft plastic peripheral lining, for example TPE. Here, too, the cavity-type elastomer seal can be used in the same way, so that an extremely elastic annular membrane is formed. In order to retain fastening elements, such as screws and the like, in the inner door element, the inner door element is provided with a molded housing. It is usually a sleeve equipped with an internal thread, which, like the above-mentioned support ring, can be made of a harder solid plastic. It goes without saying that the number and placement of the cable clips and sheaths are adapted to the particular design. Furthermore, it is proposed that the inner door element be provided with an intermediate carrier plate for mounting the engine. It is advantageous for the support plate to be a metal plate. This support plate may be adapted to receive particular elements, i.e. be provided with suitable mounting holes or latching projections and the like to retain the motor flange and the like on the support plate. Furthermore, it is also proposed that the inner door element be provided with injection molding bridges with freely accessible undersides. Through the loops thus formed it is possible, for example, to thread cables or bundles of cables or bowden cables and the like. In order to increase the mechanical stability of the inner door element, it is further advantageous if the inner door element is provided in the wall with a recess for receiving a molding. It may be a steel insert.

The aforementioned sealing body is preferably formed by a caterpillar placed on the surface of the inner door element, which can be precisely laid by the robot. During this installation, the materials adhere to each other automatically, for which eventually the increased temperature of the inner door element can be used. The sealing body is preferably housed in an integrally formed groove of the inner door element. In order not to weaken the wall of the inner door element through this groove, this groove is formed by the curvature of the wall of the inner door element and the beaded thickening on the back of the inner door element. The inner door element can thus have a total thickness of, for example, only 5 mm. In addition, the camber of the inner door element at the groove location increases the mechanical stability of the inner door element, so that said cambered groove on the opposite side also constitutes a reinforcing rib. To increase the mechanical stability of the inner door element, it is also provided that the inner door element has different masses in its cross-section, i.e., in the unexpanded top layer, has a density of between 0.7 and 1.4 g / cm ³ and in expanded core weight of 0.1 to 0.6 g / cm ³ . The density of the compacted polymeric materials is approximately 1 g / cm ³ . Due to this layered structure, it is possible to create interior door elements with high rigidity, low weight and high integration potential, i.e. with the possibility of retaining many other diverse structural elements. Also provided for this purpose is that the injection molding foam material of the inner door element comprises an HMS component (High Melt Strentghj-Polypropylene-based polymer) which increases the melt stability of the copolymer, the proportion of the base component being approximately 90% by weight. The structurally isomeric propylene polymer will expand its processing conditions to achieve a defined chamber formation and uniform size, thus achieving a largely homogeneous structure of the inner door element. In this regard, it is proposed that the injection molding material of the inner door element contain fillers. In this way, the stiffness of the inner door element, which at the same time has a low weight, can be further increased, which can be approximately 20% by weight of glass fibers or talc. The inner door element was on the front of your circuit equipped with anchorage passages that are equipped with an integral molding formed massive unloading. These sleeve-shaped linings are connected on both sides of the inner door element with transversely extending massive upper layers of the inner door element. Said linings also reinforce the respective area so that the fastening elements inserted therein, for example self-tapping screws and the like, are firmly fastened even though the surrounding material has a low density. In this respect, it has further proven to be advantageous if the anchoring passage is encircled from the front side of the circumference by a projecting integrally formed lobe. Such a lobe increases the area surrounding the anchoring passage, around which there is more material of the inner door element. Furthermore, it is also advantageous if sleeves, threaded sleeves and the like are sprayed in the inner door element. These may be metal inserts. A further preferred embodiment of the inner door element, even with a separate meaning, is that in the surface of the inner door element its material is partially removed or an impassable cut is made to provide access to its lower specific weight core. In this case, the impermeability of the inner door element is maintained. Only one of the solid top layers of the inner door element is cut, thereby providing the anchoring element with the desired access to the core of the inner door element. In particular, this is accomplished such that the exposed core regions serve as access to the anchoring means. A further solution of the inner door element, with a separate meaning in itself, is to provide fasteners in the inner door element while retaining the integral top layer. It may be a pivoting anchor whose star-like or cross-shaped arms cut into the sides of the grooves, these grooves being positioned as a centering star or cross.

DETAILED DESCRIPTION OF THE INVENTION

In the door 4 of the motor vehicle shown in vertical section in FIG. 2, an inner door element 3 is disposed in their interior space 2 and extends substantially vertically in the assembled door 1.

The inner door element 3 completely overlaps and at the same time seals the opening 4 in the inner door panel 5, which is designed as a frame.

On the outside, the inner space 2 of the door 1 is delimited by an outer door panel 6.

On the side of the interior of the motor vehicle, the interior space 2 of the door 1 is closed by a panel 7. Below this panel 7, a liner 8, so-called padding, can still project on this side.

A step 9 is formed at the edge of the opening 4 in the inner door panel 5, which forms a circumferentially extending support edge 11). Thus, the periphery 11 of the inner door element 3 can abut on the edge of the opening 4.

Said perimeter 11 abuts the support rim 10 via a sealing body 12 which is formed on the perimeter 11 of the inner door element 6 by spraying foam during manufacture of the inner door element 3. The sealing effect against the support rim 10 with the corresponding circumference is further enhanced by cavity 13 in active. The sealing body 12 is an elastomeric seal with a through cavity 13. The cavity 13 is formed simultaneously with the production of the sealing body 12 by gas blowing. The respective gas may be introduced through one or more cannulae. The punctured holes in these cannulae can be closed by themselves.

To the perimeter 11 of the inner door element 3, the facing fastening foot 14 of the sealing body 12 extends over the corner of the perimeter 11 of the inner door element 3 towards the outside of the door 1. Of course, it is possible for the fastening foot 14 of the sealing body 12 the side 15 of the circumference 11 of the inner door element 3, extends over the entire front side 15 or has been anchored to the front side 15. As can be seen from the enlarged section in FIG. 3, a thin layer 16 extends over the entire contact surface between the sealing body 12 and the inner door element 3, through which the elastomeric material of the sealing body 12 does not penetrate and which at the same time forms the binding layer.

For the door module, i.e. the inner door element 3, polypropylene, polyamide, acrylonitrile / butadiene / styrene or PET with a foaming blowing agent, which may be endothermic or exothermic, may be used as the material. The foaming or expansion is performed at approximately 50% of the initial specific gravity. During this foaming process, the inner door element 3 will acquire its final form and equipment as will be described further below. A suitable material for the sealing body 12 is TPE, for example TPE-V or SEBS. This material is also used for the holes described below and the like.

The advantages of the molding process can best be exploited by an inner door element 3 produced, for example, by a two-color injection molding process. In this way it is possible to realize complicated geometric shapes and various thick walls and at the same time to connect other elements. The inner door element 3 is light, stable and acts as a damping or insulating body.

On the inner door element 3 according to FIG. 4 shaped cable clamps 17. This clamp 17 consists of two freely protruding spring arms 19 which are oriented perpendicular to the main plane of the inner door element 3. The spring arms 19 extend towards the inner door element 3 and are formed therebetween in the transverse direction the plug hole 20 for the cable 18 extending in the direction of the web. The plug hole 20 is slightly undercut so that the cable 18 between the spring arms 19 is locked.

In FIG. 5, instead of laying the cable 18 on the inner door element 3, the passage of the cable 18 through the inner door element 3 is shown. For this purpose, a cable gland 21 is formed in the inner door element 3. This is formed by an opening 22 in the inner door element 3 and arcuately extending a sealing mouthpiece 23 which tapers towards its free end up to a cross-section of cable 18 or more, thereby achieving sealing of the cable 18. Said sealing mouthpiece 23 may be of the same material as the sealing body 12. Forming to the glazed outer side of the inner door The sealing mouthpiece 23 may also have a straight shape instead of the arcuate shape shown and be positioned perpendicular to the main plane of the inner door element 3. It is also possible that the sealing mouthpiece 23 is additionally bent according to the desired diameter cable routing 18.

In the cable gland 21 shown in FIG. 6, instead of the protruding sealing mouthpiece 23, the opening 22 is used substantially in the thickness of the inner door element 3. The cable gland 21 is here formed by a circumferential lining 24 of the opening 22 which is preferably of the same material as the sealing body 12. 24 may be similar to the sealing body 12. Also in this case a circumferential cavity 25 may be used. This results in a diaphragm practically filling the opening 22, and after the cable 18 has been inserted into the central opening in the cable gland 21 abuts.

FIG. 7, a threaded sleeve 26 with an internal thread 27 for a fastening element 28 is shown which is designed as a screw with a corresponding external thread. Said casing 26 extends perpendicular to the main plane of the inner door element 3 and is disposed in a curvature 29 with a rectangular cross-section 11 in the inner door element 3. The housing 26 is anchored at the bottom of the camber 29 and extends into the interior space 30 of the camber 29. in this case, the sleeve 26 does not exceed the length of the fastening element 28. The free front edge of the sleeve 26 is substantially flush with the left outer side of the inner door element 3.

In FIG. 8 shows a support ring 31 for receiving a loudspeaker 32, which is indicated by dotted lines and is provided with a support rim 33. This loudspeaker 32 is adapted to be mounted on its periphery to the support ring 31 for example. hard polyvinyl chloride.

The annular support ring 31 is exposed positioned at the profile edge 34 of the corresponding aperture 35 in the inner door element 3. The cross-section of this profile edge 34 has the shape of a tapered cone. The support ring 31 has a rectangular or square cross section. The outer side of the support ring 31 facing the inner door element 3 is fully supported on the profile edge 34 with its entire surface. This also applies to half the height of the outer circumferential side of the support ring 31. The fastening is similar to the sealing body 12. 35 is flush with the inner circumference of the carrier ring 3 1.

The rotationally symmetrical tapered profile edge 34 mechanically stabilizes the region of the support ring 31.

A further modification of the inner door element 3, which serves to retain another element in the rightwardly domed region 38 of the inner door element 3, is apparent from FIG. 9. In this case, it is an intermediate carrier plate 36 which forms the carrier base for the motor 37, which is indicated by dotted lines. In the domed area 38, a shoulder 39 is formed which corresponds to the contour of the support plate 36, the outer edge of which is covered by the edge flange 40 of the inner door element 3, which defines a window 41 in which a motor 37 can be mechanically stably mounted. the inner periphery 42 of this window 41.

The illustrated carrier plate 36 is provided with slot projections 43 which engage into the die bore 44. This may be an irreversible snap joint. The tactile protrusions 43 are in the form of mushroom-like snap-in elements, which with their rear edges engage beyond the edge of the matrix opening 44.

The carrier plate 36 may be of metal.

In FIG. 10 shows a bridge 45 which is injection molded on the inner door element 3. The underside 46 of the bridge 45 is freely accessible. This is a cut-off area of the surface of the inner door element 3, which is pushed out of the main plane of the inner door element 3. This results in a passage 47, for example for threading the cable 18 or as shown in FIG. 10, the bowden pull 48. The structure of the sections is apparent from FIG. 1 in the area designated X-X.

The inclined surfaces of the underside 46 of the bridge 45 may be provided with projections (not shown) for gripping the bowden pull 48 on its sheath.

The wedge portions of the cross-section of the passage 47 in the bridge 45 that are not filled with the bowden pull 48 may be filled with sealant if necessary.

Finally, as shown in FIG. 2, in the central part of the surface of the inner door element 3, a recess 49 is formed in its wall that faces the interior of the motor vehicle. In this way, a groove 50 is formed in the inner door element 3, for example for receiving a reinforcing element, which is designed as a sheet insert 51 of steel. The groove 50 has a trapezoidal cross section.

These and other significantly reinforced areas of the inner door element 3 as well as the support plate 36 provide a good base for the installation of the crank mechanism for ejecting the glass and its spindles, levers and the like.

The inner door element 3 can be screwed onto the support rim 10. Gluing can also be used.

A variant of the inner door element 3 shown in FIG. 11, also consists of splashed foam material. A large group of thermoplastics can be used, such as polypropylene, polyamide, acrylonitryl / butadiene / styrene, PET, polycarbonate, PBT, and others. In order to achieve special material properties, two types of polypropylene are joined together. The base component, which represents up to 90% by weight, is a copolymer. Block copolymers with lower α-olefins, especially ethylene, generally exhibit higher impact resistance. In order to increase the melt stability of the copolymers, a polypropylene-based polymer is added to the base component of the HMS (high melt strenght). Due to this structurally isomeric propylene polymer, the range of processing conditions is expanded and stable cell growth and uniform cell size are achieved.

Fillers and reinforcing materials are added to the foam injection material, i.e. to the polymeric materials. It is up to 20 wt. glass fibers or talc. These stiffening materials increase the stiffness of the inner door element 3.

Also in this case, the construction of the inner door element 3 is based on a layered structure composed of layers of different densities. In practice, this is done so that the specific weight of the inner door element 3 in its cross-section is first about 0.7 to 1.4 g / cm ³ in the unexpanded topsheet 52. By the topsheet 52 is meant the major surfaces of the inner door element 3, not the front sides 15 of the periphery 11 of the inner door element 3 mentioned above, although the topsheet 52 extends to the periphery 11 where it passes into the peripheral layer 53 which constitutes the substrate. The density of the core 54 of the inner door element 3, which is closed by the massive upper layers 52 and the outer layers 53 and constituted by the expanded porous layer, is in contrast 0.1 to 0.6 g / cm ³ .

Surprisingly, the foam structure of the thermoplastic foam casting has a high homogeneity, which almost penetrates the massive topsheet 52 so that the desired hard topsheet is closed on all sides.

While the solid topsheet 52, including the perimeter layer 53, cannot be pierced naturally without additional equipment, it is possible to pierce or cut through the sealed core 54 in these layers 52, 53 with little force. The usefulness of this will be further described.

The required high E-modulus of the upper layers 52 and the outer layers 53 is achieved even with a relatively small proportion of the thicknesses 52, 53 on the total thickness of the inner door element 3. For a total thickness of the inner door element 3 of about 5 mm about 0.4 mm and a thickness of the peripheral layer 53 of about 0.7 mm. The stiffness of such topsheets 52 is approximately 2500 N / mm ² . In contrast, the stiffness of the core 54 is only about 600 N / mm ² .

All of the above creates the prerequisites for the interior door element 1 to be able to grip well the components that are normally housed in the door 1 of a motor vehicle, such as loudspeakers, loudspeaker assemblies, cable grips 17 and these cables 18 themselves, at least some.

The sealing body 12 is in this case formed solely by a bead placed by the machine on the inner door element 3. This bead is continuously laid on the surface 55 of the inner door element 3. It is a foam body with an integrally formed highly elastic cover layer 56 as shown. FIG. 13. wherein the cover layer 56 is indicated by a single line. A good anchoring of the sealing body 12 is sufficient here for its mushroom cross-section, the heel of which is embedded in a groove 57 which was already formed during the injection molding of the foam 55 in the inner door element 3. The walls of this groove 57 are formed by an upper layer 52. on this side it is located on the surface 55 of the inner door element 3. The sides and the bottom of the groove 57 are consequently sufficiently mechanically rigid because they are also supported by a relatively resistant core 54 of the inner door element 3.

In the seating area of the sealing body 12, the mechanical conditions are optimal and stable, since the groove 57 is formed by an overlap of the wall of the inner door element 3. There is no reduction in the thickness of the inner door element 16 because 58.

It will be appreciated that the width of the reinforcement 58 significantly exceeds the clear width of the groove 57. The ratio of these widths is approximately 2: 1.

The reinforcement 58 has a constant height over its course and leaves this plane only if the course of the support rim 10 at the step 9 of the inner door panel 5 of the motor vehicle door 1 changes. The groove 57 has a depth such that its bottom, which is formed by the solid topsheet 52, is substantially in the plane of the topsheet 52 on the back 59 of the inner door element 3.

The anchoring of the foot of the sealing body 12 in the groove 57 is supported by the mutual adhesion of the contact surfaces. Thermoplastic adhesion of the soft-foam sealing body 12 occurs.

Fig. 13, where the location of the sealing body 12 is shown, also in connection with FIG. 11 special punching for passage of fasteners. In FIG. 11, it is shown in the area of section XIII-XIII that anchoring passages 60 are unevenly distributed on the front side 15 of the inner door element circumference 11. Although the holes could be additionally perforated or laser-cut openings, it is preferred that the anchors shown the passages 60 are already formed during the injection molding of the foam. The interior of the anchorage passages 60 then has, according to FIG. 13 has the same structure as described above in relation to the topsheet 52 and the peripheral layer 53. i.e., the topsheet 52 is located on the inner periphery of the anchorage passage 60. In other words, by integrally forming the anchorage passages 60, their massive stabilizing lining 61 is achieved. This lining 61 is in the form of a sleeve which, in the form of a hollow rivet, constitutes a solid material bridge between the two upper layers 52, between which the core 54 of the inner door element 3 is located. As a result, after insertion and tightening of the fastening element, for example a screw, or in the event of excessive force, the inner door element 3 is not compressed so easily. Conversely, a restoring force is achieved by the restoring forces, which contributes to the reliability of the gripping of the inner door element 3. The described anchoring passages 60 simultaneously represent anchors that connect the top layers 52 together, thereby significantly increasing the mechanical stability of the inner door element 3. Due to the close proximity of the groove 57, it also extends to the seating area of the sealing body 1.2. At the same time, a mechanical stabilization of the entire circumference 11 of the inner door element 3 formed by the foamed body is achieved.

As further evident from FIG. 11, the anchoring passage 60 on the front side 15 of the perimeter 11 is encircled from this front side 15 by a projecting lobe 62, also integrally formed. trapezium. The outer periphery of the inner door element 3 is thus enlarged to such an extent that the axes of the generally circular anchorage passages 60 are then located on the front side line 15 of the periphery 11 of the inner door element 3. Into these anchorage passages 60 or other passages in the surface of the inner door element 3 also in this case, the usual bushings, threaded inserts and the like are inserted, which is preferably done by spraying these elements. Sufficient details in this respect have already been given in relation to the basic version of the inner door element 3.

In FIG. 15, a particular feature of the inner door element 3 is shown in that in its rear side 59 there is a prominent protrusion 63 which has the shape of a dome at its rear side 59 in order to achieve a sufficient depth of screwing of the fastening element which is not to protrude from the inner door element. The topsheet 52 on the opposite side, i.e. on the surface 55 of the inner door element 3, runs in parallel to the main plane of the inner door element 3. Such local reinforcements or protrusions are also used in the basic version of the inner door element. 3 and described therein in connection with FIG. 4 and 9 therein, in order to ensure a good anchorage of the carrier plate 36 to the edge flange 40, where the shoulder 39 is provided in cross-section with a reinforcement exceeding the thickness of the inner door element 3, which is essentially plate-shaped.

While the passage anchorage passages 60 are essentially only provided within the surface of the sealing body 12, the passage anchorage passages formed in the inner region of the inner door element 3, i.e. in the region located within the periphery of the seal body 12. The sealing effect of the inner The door element 3 'also acts as a partition wall. This prevents the passage of moisture.

The attachment of the respective anchoring means 64, in which case it may be a cable or bowden cable clamp or the like, is achieved in two different ways. The first of these methods consists in that, according to FIG. 21 to 23 partially mills the material. The reference numerals of the preceding embodiments are used without being repeatedly explained here. For this purpose, in the foam injection molding process, a recess is formed on the respective side of the inner door element 3 which extends into the core 54. According to FIG. 22 and 23, it is a tray 65 in the form of an elongated opening. This tray 65 of FIG. 22 extends to the vicinity of the lower massive topsheet 52, so that a certain thickness of the core material 54 is retained despite the introduction of the milling cutter (not shown), the oval wall 66 of the tray 65 is milled across the main plane of the inner door element. The respective anchoring means 64 is introduced and the desired anchorage is formed when it is inserted. Indeed, minimal scraping is sufficient because the milling cutter has access to the core 54 with a lower material density.

The anchor 67 which is inserted into the tray 65 is provided parallel to the main plane of the inner door element 3 extending through the tongue 67 '. In the direction of rotation of the armature 67 at the rear side of the armature 67, a protruding pawl 68 may be formed which counteracts the spontaneous reversal of the armature 67.

If a greater depth of penetration of the armature 67 is to be achieved, it can be shown in FIG. 21 locally increase the thickness of the core 54 so that a protrusion 63 is formed at this point and a tray 65 is formed in the topsheet 52.

According to FIG. 21 to 23, the anchoring means 64 is an object having only one anchor 67.

Another situation is in the case of FIG. 17 to 20, which show another method of anchoring the anchoring means 64. The tray 65 here has the shape of a paw cross, so that. This is a cross tray 65. However, chip machining is not used here. Instead, the anchoring means, for example as a buckle, is retained in the inner door element 3, while retaining the integral topsheet 52. This means that neither the topsheet 52 in the region of the tray 65 nor the oval wall is removed. The correspondingly shaped anchor 67 also has the shape of a cross. Its four arms, which are arranged at equal angles to one another, or blades 67 'on these arms, extend below the remaining regions 69 of the inner door element 3, cutting the path through the oval wall 66 of the tray 65 by themselves. reaches the closure of the cut road again. Also in this case, punches 68 are used that protrude from the arm of armature 67. As f

as a whole, a centering system of depressions for self-cutting anchors of the pivots of the anchor 67 of the anchoring means 64 is formed.

A free-standing base 70 with a non-circular sheath protrudes from the plane of the anchor 67 above the rim of the tray 65, further facilitating the fixation of the anchoring means 64 when the auxiliary rotary tool is mounted. The non-circular cross-section of the base 70 can be hexagonal so that .

It is not necessary for the pedestal to be integral with the coaxial adjoining buckle 71. The flattened buckle 71 is then also not used as a handle and is connected to the pedestal 70 by a screw connection. This embodiment also has the advantage that the clip 71 can be conveniently adjusted relative to the object to be fastened, for example a bowden pull. Thus, the angular position or the final rotation of the pedestal 70 is irrelevant.

All the features described are significant to the invention. The content of the application in this sense also includes the content of the respective priority ones
