State of the art

From the DE 10 2019 200 093 A1 a sequin with at least one electrical or electronic functional element is shown, which can be fastened and electrically contacted to a piece of clothing.

Disclosure of Invention

Against this background, the approach presented here presents a functional application, in particular a rod bead, for a textile element, in particular for a piece of clothing, with a carrier element having a continuous, in particular tubular, recess. In this case, the recess delimits an inner surface of the carrier element from an outer surface of the carrier element. The functional application also includes at least one first electrical contact and at least one additional electrical contact, which is separate from the first electrical contact, in particular a second electrical contact, for electrically contacting an electronic component that is or can be arranged in and/or on the carrier element. In this case, the first electrical contact is arranged on the inner surface of the carrier element and the at least one further electrical contact is arranged on the outer surface of the carrier element. The functional application is characterized in that the carrier element has an essentially elongate shape and a longitudinal axis of the carrier element is arranged parallel or concentrically to a longitudinal axis of the recess.

An appliqué or appliqué can be understood to mean a specially worked element that is often used for decoration and is suitable for being attached or arranged on a textile element, in particular on a piece of clothing. Here, the appliqué can preferably have a three-dimensional design, such as a bead and in particular a stick bead, which can be sewn or embroidered onto the textile element using a thread. An application can have metal or plastic, for example. A functional application can be understood as an application that is provided with further electrical, electronic, optical or mechanical components or a combination of these components. An optical component can be understood as an LED, for example.

A functional application can therefore have sensors, actuators and/or acoustic, haptic and/or optical signal transmitters. A carrier element can be understood, for example, as a base body on or in which the aforementioned components can be arranged or integrated. A carrier element with a continuous recess can be understood to mean a base body which has a tubular, continuous hole. In this case, the recess can have a cylindrical, square or other arbitrarily shaped cross section, at least in some areas.

The carrier element can, for example, have a miniaturized, flexible and/or encapsulated printed circuit board, the printed circuit board being shaped as a hollow cylinder or rolled up to form a hollow cylinder and being encapsulated at least in regions with a plastic.

In this case, the recess corresponds to the interior of the hollow cylinder, which delimits the inner surface from the outer surface of the carrier element. In this case, the components can be arranged on the side of the printed circuit board which points to the inner surface of the carrier element, and can also be arranged on the other side of the printed circuit board which points to the outer surface of the carrier element.

The components can be contacted for signals and/or energy by the first electrical contact arranged on the inner surface of the carrier element and the second electrical contact arranged on the outer surface. In this case, the second electrical contact can have an electrical connection from the outer surface through the carrier element to the printed circuit board or to the component. The first electrical contact and/or the second electrical contact can be provided and set up to attach and/or electrically contact the functional application to a textile element, in particular to a piece of clothing. In this case, the same means can preferably be used to attach the appliqué to the textile element or to the item of clothing and to contact it electrically.

A substantially elongate shape of the carrier element can be understood to mean that the carrier element has a length that is greater than a diameter, a width or a height of the carrier element, in particular that the length more than 1.5 times, preferably more than twice, the diameter, the width or the height. The support element can be designed to be rotationally symmetrical, at least in certain areas. A parallel or concentric arrangement of the longitudinal axis of the carrier element to the longitudinal axis of the recess can be understood to mean that the elongated shape of the carrier element and the recess essentially point in the same direction with or without a lateral offset. This is the case, for example, with an appliqué designed as a rod bead, the rod bead having a recess for the passage of a thread, the longitudinal axis of which runs essentially parallel to a longitudinal axis of its elongated, outer shape or coincides with it.

Advantages of the Invention

The functional application has a particularly compact design due to its three-dimensionality. As a result, the components integrated in the application can be arranged in a particularly space-saving manner in comparison to a flat functional element. Accordingly, the application takes up very little space on a textile element on which it is arranged or integrated, so that even more complex circuits with several of these functional applications can be implemented on a relatively small area on the textile element.

Furthermore, due to the special design of the functional application, the electronic components arranged in particular on the inner surface of the carrier element are particularly effectively protected against external influences. This is because a functional application arranged on a textile element or item of clothing is subject to impacts, kinks or friction during typical use of the textile element or item of clothing. Due to the special design of the application, the application is particularly resistant to these influences and potential damage.

Through the recess, the functional appliqué can be attached to the textile element or item of clothing in a particularly simple and robust manner by means of a thread, yarn or twine. Furthermore, the first electrical contact of the carrier element can be electrically contacted by means of a conductive thread, which is guided through the recess. In particular, both the electrical contacting of the first electrical contact of the carrier element and the mechanical attachment of the functional application to the textile element or item of clothing can be realized by means of the electrically conductive thread.

Further advantages result from the dependent claims.

In a preferred embodiment it can be provided that the carrier element has two or more electrical contacts, preferably a third and a fourth electrical contact, on the outer surface, the two or more electrical contacts being separated from one another and from the first electrical contact. As a result, several different electronic components can be electrically contacted within the functional application. An area of application of the functional application is thus expanded in a simple manner and it is made possible for more complex electronic circuits to be implemented within the application.

In a further embodiment it is further provided that the first electrical contact is designed as a first electrical contact surface and at least partially covers the inner surface of the carrier element and/or the at least one further, in particular the second, electrical contact as at least one further, in particular second, electrical contact surface is formed and at least partially covers the outer surface of the carrier element. As a result, the electrical contacts can be contacted in a particularly simple manner. This can be implemented, for example, by means of an electrically conductive thread lying against or resting on the electrical contact surface. The entire inner surface of the carrier element can preferably be designed as an electrical contact surface. Furthermore, the entire outer surface of the carrier element can preferably be designed as an electrical contact surface, with the first electronic contact surface being electrically separated from the one further electronic contact surface. The electrical contact surfaces can be implemented, for example, by vapor deposition of a conductive material, in particular a metal, or by means of a conductive, drying paste.

In a further preferred embodiment, it is also provided that the at least one further electrical contact extends as an at least partially strip-shaped or ring-shaped electrical contact surface essentially perpendicular to a longitudinal axis of the carrier element, in particular along a circumference of the outer surface, on the outer surface of the carrier element. In this way, the at least one further electrical contact can be electrically contacted in a particularly simple manner by an electrically conductive thread essentially perpendicular to the Longitudinal axis of the carrier element is guided over the outer surface in the region of the strip-shaped or ring-shaped electrical contact surface. Furthermore, the functional appliqué can advantageously be fixed mechanically to the textile element or item of clothing by means of the electrically conductive thread guided over the outer surface of the carrier element.

Furthermore, it is additionally advantageous if the outer surface has an at least partial constriction and/or indentation in the region of the at least one further electrical contact. As a result, an electrically conductive thread, with which the at least one further electrical contact is contacted, can be held in position in a particularly simple manner and secured against slipping in the longitudinal direction of the carrier element. This ensures reliable contacting of the at least one further electrical contact and the functional application is also particularly securely attached to the textile element or item of clothing. Since the constriction and/or indentation has a substantially smaller diameter than the appliqué itself, thread material can also be saved.

In a further preferred embodiment it is further provided that the constriction and/or the indentation is formed rotationally symmetrically in relation to a longitudinal axis of the carrier element and/or a longitudinal axis of the recess. This can be understood to mean that the constriction and/or the indentation runs at least partially or completely along the outer surface of the carrier element perpendicular to the longitudinal axis of the carrier element. The constriction and/or the indentation can preferably be in the form of a ridge, groove or furrow. As a result, particularly reliable electrical contacting of the at least one further electrical contact and, at the same time, particularly robust mechanical fixing of the appliqué to the textile element or the item of clothing can be achieved.

In a further embodiment, it is further provided that the outer surface of the carrier element is configured essentially rotationally symmetrically around a longitudinal axis of the carrier element, at least in regions, in particular in a region on which the at least one further electrical contact is arranged. On the one hand, this simplifies the electrical contacting and the mechanical fixing of the functional application to the textile element or item of clothing. On the other hand, the robustness of the functional appliqué, in particular when it is attached to the textile element or item of clothing, is increased by the rotational symmetry with respect to wear and/or damage occurring during typical use of the textile element or item of clothing.

In a further embodiment it is additionally provided that the carrier element has rounded edges or rims at a first transition area, where the inner surface borders on the outer surface, and/or at a second transition area opposite the first transition area. A transition area can be understood here in particular as the area where a thread, in particular an electrically conductive thread, passed through the recess of the carrier element enters the recess and/or exits the recess and is guided there in the direction of the textile element or item of clothing in order to to be mechanically connected to the textile element or garment. Rounded edges or rims can be understood here as meaning that the edges or rims have a radius of 1 mm, preferably 2 mm, particularly preferably 5 mm. This minimizes mechanical stress from chafing and/or rubbing at the edges or margins of the thread guided through the recess of the carrier element during typical use of the textile element or item of clothing mechanically connected to the functional appliqué.

In a further embodiment, it can also be provided that the carrier element has a first end face and/or a second end face opposite the first end face, the first end face and/or the second end face being at least partially perpendicular to a longitudinal axis of the carrier element and/or is arranged to a longitudinal axis of the recess. For example, the first end face and/or the second end face can adjoin the rounded edges or rims on the first transition area and/or on the second transition area, in particular in the manner of a circular ring. The first end face and/or the second end face can form part of the outer surface of the carrier element. Alternatively, the first end face and/or the second end face can form an interface between the inner surface and the outer surface of the carrier element, on which no electrical contacts are arranged. As a result, the functional appliqué can be handled in a particularly simple manner during a method for attaching the appliqué to a textile element or item of clothing. In particular, this makes it easier to receive and equip several functional applications in a storage container and to subsequently process the applications.

In a further embodiment, it is also provided that the carrier element has a transparent plastic, such as polymethyl methacrylate or acrylic glass, at least in regions. This embodiment is particularly suitable for functional applications with light sources, such as LEDs, so that the optical signaling emitted by the light source can be transmitted through the carrier element or the application.

In a further embodiment it is further provided that the carrier element has an opaque plastic at least in regions. This embodiment is advantageous if at least certain components of the functional application are to be arranged so that they cannot be seen, in particular for optical or aesthetic reasons, or are to be protected from sunlight.

In a preferred embodiment, it can be provided that the carrier element has both a transparent plastic and at least in some areas a non-transparent plastic.

The aforementioned advantages also apply in a corresponding manner to a textile element with an appliqué according to one of the previously described embodiments. A textile element can in particular be a piece of clothing.

A preferred embodiment of the textile element provides that the carrier element is attached to the textile element by means of a first electrically conductive thread and that one of the electrical contacts, in particular the first electrical contact, is electrically contacted by means of the first electrically conductive thread. In this case, the carrier element can be sewn or embroidered onto the textile element or mechanically connected to the textile element via another similar connection. As a result, the electrically conductive thread can advantageously be used to make electrical contact as well as to mechanically fix the application to the textile element.

In a further preferred embodiment it can be provided that the carrier element is fastened to the textile element by means of at least one further electrically conductive thread and that the further electrical contact other than the one electrical contact contacted with the first electrically conductive thread, in particular the second electrical Contact is electrically contacted by means of at least one further electrically conductive thread. As a result, the robustness of the mechanical fixing of the appliqué to the textile element can be further increased and at the same time the functional appliqué can be contacted at the at least one further contact in terms of signals or energy. In particular, in the case of several separate, further electrically conductive threads, which each contact separate electrical contacts on the outer surface of the carrier element, the complexity of an electrical or electronic circuit in the functional application can be increased and the attachment of the application to the textile element can be further improved.

The aforementioned advantages also apply in a corresponding manner to a method for attaching a functional appliqué according to one of the previously described embodiments to a textile element. The textile element can be understood to mean a textile element of the previously described embodiments. The method has at least one step of providing and positioning the application on the textile element. Furthermore, the method has a step of guiding a first electrically conductive thread through the recess of the carrier element. There is also a step of attaching the first electrically conductive thread, in particular in a region of at least one end face of the carrier element, to the textile element in such a way that the first electrically conductive thread makes electrical contact with the first electrical contact of the carrier element.

In a preferred embodiment of the method, the application is positioned on an upper side of the textile element. A sewing needle guiding the electrically conductive thread then pierces the recess of the carrier element of the application and the textile at a first position on the textile. The thread is then looped on an underside of the textile element and the sewing needle is pulled out of the recess together with the thread. After this, the sewing needle guiding the thread pierces the textile element at a second position, with a distance between the second position and the first position essentially corresponding to a length of the appliqué. The electrically conductive thread is then intertwined on the underside of the textile element in such a way that the electrically conductive thread makes electrical contact with the first electrical contact of the carrier element. Finally, the sewing needle together with the thread is pulled out of the textile element again.

In a further preferred embodiment, the method has a step of transferring at least one further, in particular a second, electrically conductive thread over the outer surface of the carrier element. Continue the method has a step of attaching the at least one further electrically conductive thread to at least one area on the side of the outer surface, in particular on both sides of the outer surface, of the carrier element on the textile element. In this case, the fastening takes place in such a way that the at least one further electrically conductive thread makes electrical contact with the at least one further first electrical contact of the carrier element and that the first electrically conductive thread and the at least one further electrical thread are electrically separated.

According to a further preferred embodiment of the method, the sewing needle pierces the textile at a third position to the side of the outer surface of the carrier element on the textile, the sewing needle guiding an electrically conductive thread. The electrically conductive thread can be the previously mentioned thread or another electrically conductive thread. The thread is then intertwined on the underside of the textile element and the sewing needle and thread are pulled out of the textile element. Finally, the sewing needle together with the electrically conductive thread is pierced into the textile element at a fourth position on the textile element, the fourth position being on a side of the outer surface opposite the third position. Finally, the electrically conductive thread is intertwined on the underside of the textile element in such a way that the electrically conductive thread electrically contacts the at least one other electrical contact on the outer surface of the carrier element, whereupon the sewing needle together with the electrically conductive thread is pulled out of the textile element.

As already explained above, the present invention describes a functional application for a textile element, a textile element with such a functional application, and a method for attaching a functional application. As a result, a robust, functional application that requires little installation space can be implemented in a particularly simple manner. This application attached to a textile element or piece of clothing makes it possible to equip the textile element or piece of clothing with complex electronic functions and thus form a “smart” textile element.

In 1 a functional application 1 is shown from a perspective view. The functional application 1 is designed as a rod bead 2 with an elongated shape. The rod bead 2 can, for example, have an outer diameter of approximately 2 mm to 3 mm and a length of, for example, 4 mm to 10 mm. The appliqué 1 comprises an elongate carrier element 5 which is designed to be essentially rotationally symmetrical about a longitudinal axis 40 . The carrier element 5 has a continuous recess 12 which delimits an inner surface 14 from an outer surface 16 of the carrier element 5 or of the application 1 . The recess 12 can be tubular with a particularly circular cross-section. The recess 12 is preferably aligned in the direction of the longitudinal axis 40 of the carrier element 5 . In particular, a longitudinal axis of the recess 12 can be identical to the longitudinal axis 40 of the carrier element 5 . The carrier element 5 comprises a circuit board 30 on which electronic components 32, such as an LED, are arranged. The printed circuit board 30 can be designed as a flexible printed circuit board 30 so that it essentially forms a hollow cylinder when bent around the longitudinal axis 40 . Both on The electronic components 32 can be arranged on one side as well as on the other side of the printed circuit board 30 . The electronic circuit board 30 and the electronic components 32 can be cast with a plastic and thus form the inner surface 14 and the outer surface 16 of the carrier element 5 . The plastic can be partially transparent. This is particularly useful when a signal, for example from an LED, is to be transmitted to the outside through the application 1 . In this case, the plastic can have, for example, polymethyl methacrylate or acrylic glass. As an alternative or in addition, the plastic can be made non-transparent or opaque in some areas in order, for example, to optically shield the printed circuit board 30 or the electronic components 32 from the outside or to protect them from the incidence of light.

A first electrical contact 20 is arranged on the inner surface 14 . In this case, the first electrical contact 20 is designed as an electrical contact area which essentially completely covers the inner surface 14 . Alternatively, it can be provided that the electrical contact area covers the inner surface 14 only in regions. The first electrical contact 20 is connected to the printed circuit board 30 or directly to the electronic components 32 in terms of signals and/or energy (not shown).

A second electrical contact 22 is formed on the outer surface 16 as an electrical contact area, which covers the outer surface 16 in the form of a strip or ring. In this case, the strip-shaped electrical contact 22 is arranged essentially centrally on the outer surface 16 and can cover the outer surface 16 at least in regions or completely along a circumference perpendicular to the longitudinal axis 40 . The appliqué 1 or the carrier element 5 has a constriction 7 on its outer surface 16, at which a diameter or a lateral dimension of the appliqué 1 is smaller than at the other areas of the outer surface 16. The second electrical contact 22 is for signals and/or connected in terms of energy to the printed circuit board 30 or directly to the electronic components 32 (not shown). The constriction 7 is advantageously designed to be rotationally symmetrical in relation to the longitudinal axis 40 . The outer surface 16 can also be designed to be rotationally symmetrical with respect to the longitudinal axis 40, preferably in an area on which the strip-shaped electrical contact 22 is applied.

The recess 12 and the first electrical contact 20 are designed to accommodate or guide an electrically conductive thread, with which the appliqué 1 can be mechanically attached to a textile element and electrically contacted. The second electrical contact 22 is designed so that a further electrically conductive thread can be placed on it in order to additionally mechanically fasten the appliqué 1 and make electrical contact. The constriction 7 is particularly useful here, since it secures the electrically conductive thread against slipping and thus ensures a particularly robust mechanical connection and electrical contact with the textile element. The electrically conductive thread can, for example, comprise a polyamide yarn or thread and have a maximum tensile strength of 500 cN-1500 cN, preferably 750 cN-1250 cN and particularly preferably 900 cN-1100 cN. The electrical resistance of the electrically conductive thread can be less than 500 ohms/m, preferably less than 300 ohms/m and particularly preferably less than 200 ohms/m. The textile element can be designed as a textile surface, in particular a woven fabric, a fleece and/or a knitted fabric, with the lowest possible stretch or elasticity. A basis weight of the textile element can be, for example, approximately 80 g/m ² to 200 g/m ² .

In 2 a functional application 1 is shown in a plan view. The functional application 1 essentially corresponds to the functional application 1 from 1 , A first end face 50 and/or a second end face 51 of the outer surface 16 now being configured substantially perpendicularly to the longitudinal axis 40 . This is particularly advantageous in a method for attaching the appliqué 1 or the rod bead 2 to a textile element, since it makes it easier to handle the appliqué 1 on the textile element while it is being sewn to the textile element with a thread. Furthermore, the carrier element 5 can have rounded edges at a first transition area 55 and/or at a second transition area 56 . The rounded edges in the first transition area 55 and/or in the second transition area 56 can have a radius of 1 mm, preferably 2 mm and particularly preferably 5 mm or more, so that a thread guided in the recess 12 and running over the edges which the application 1 is attached to the textile element is mechanically stressed as little as possible by friction.

The functional sequin 1 is in the form of a rod bead 2 with an elongated shape.

In 3 a functional application 1 is shown from a perspective view. The functional application 1 essentially corresponds to the functional application 1 from 1 , On the outer surface 16 now three separate electrical contacts 22, 22a, 22b in Substantially parallel to each other and perpendicular to the longitudinal axis 40 are arranged. Each of the additional electrical contacts 22, 22a, 22b is designed as an electrical contact surface in the form of a strip or ring with rotational symmetry about the longitudinal axis 40. Each of these electrical contact surfaces has a constriction 7, with which an electrically conductive thread can be guided over each of the other electrical contacts 22, 22a, 22b, so that on the one hand the mechanical fixing of the appliqué 1 to the textile element is reinforced and on the other hand each of the other electrical contacts 22, 22a, 22b can be contacted separately in terms of signaling and/or energy technology. Each of the additional electrical contacts 22, 22a, 22b is connected to the printed circuit board 30 or directly to the electronic components 32 in terms of signaling and/or energy (not shown).

In 4 Schematic representations of a textile element 80 are shown with a functional application 1 according to one of the examples given above. In the illustration above, an appliqué 1 designed as a rod bead 2 is fastened to the textile element 80 by means of two crossing conductive threads 82, 84. The two crossing conductive threads 82, 84 serve to connect the functional application 1 to the outside in terms of signaling and/or energy. Here, the first electrically conductive thread 82 is guided through the recess 12 of the rod bead 2 and sewn to the textile element 80 immediately before and after it. The closer this stitching 90 of the rod bead 2 with the textile element 80 is to the rod bead 2, the more robust the mechanical connection between the rod bead 2 and the textile element 80 and on the other hand the electrical contacting at the first electrical contact 20. The first electrically conductive thread 82 is also sewn to the textile element 80 at further points 90 , in particular regularly spaced apart from one another, in order to hold the first electrically conductive thread 82 stably in or on the textile element 80 . The second electrically conductive thread 84 is passed over the constriction 7 and the second electrical contact 22 of the rod bead 2 arranged at this point and sewn to the textile element 80 immediately before and after it. The closer this stitching 90 of the rod bead 2 to the textile element 80 is in contact with the rod bead 2, the more robust the mechanical connection between the rod bead 2 and the textile element 80 becomes. The second electrically conductive thread 84 is also at other points, in particular at regular intervals 90 sewn to the textile element 80 in order to keep the second electrically conductive thread 84 stable in or on the textile element 80. By guiding the second electrically conductive thread 84 over the rod bead 2, both electrically conductive threads 82, 84 remain electrically separated from one another.

The illustration below 4 differs from the upper one essentially in that both electrically conductive threads 82, 84 are arranged essentially parallel to one another. Here, a side strand 82a leads away from the first electrically conductive thread 82 in order to be guided through the recess 12 of the application 1 or the rod bead 2 in order to electrically contact them via the first electrical contact 20 and to robustly attach the rod bead 2 to the Textile element 80 to attach.

In 5 Schematic representations of a textile element 80 are shown with a functional appliqué 1 according to another of the examples set out above. In the illustration above, the appliqué 1 designed as a rod bead 2 is off 3 attached to the textile element 80 by means of a first electrically conductive thread 82 and further electrically conductive threads 84, 84a, 84b crossing this. The electrically conductive threads 82, 84, 84a, 84b serve to connect the functional application 1 to the outside in terms of signaling and/or energy. Here, the first electrically conductive thread 82 is guided through the recess 12 of the rod bead 2 and sewn to the textile element 80 immediately before and after it. The closer this stitching 90 of the rod bead 2 with the textile element 80 is to the rod bead 2, the more robust the mechanical connection between the rod bead 2 and the textile element 80 and on the other hand the electrical contacting at the first electrical contact 20. The first electrically conductive thread 82 is also sewn to the textile element 80 at further points 90 , in particular regularly spaced apart from one another, in order to hold the first electrically conductive thread 82 stably in or on the textile element 80 . The further electrically conductive threads 84, 84a, 84b are guided over constrictions 7 and the further electrical contacts 22, 22a, 22b of the rod bead 2 arranged at these points and sewn to the textile element 80 immediately before and after. The closer these stitchings 90 of the rod bead 2 to the textile element 80 are in contact with the rod bead 2, the more robust the mechanical connection between the rod bead 2 and the textile element 80 becomes regularly spaced points 90 sewn to the textile element 80 in order to keep the other electrically conductive threads 84, 84a, 84b stable in or on the textile element 80. Since the further electrically conductive threads 84, 84a, 84b are guided over the rod bead 2, the further electrically conductive threads 84, 84a, 84b remain and the first electrically conductive thread 82 are electrically separated from one another.

The illustration below 5 differs from the upper essentially in that the further electrically conductive threads 84, 84a, 84b are arranged essentially parallel to one another. Here, a side strand 82a leads away from the first electrically conductive thread 82 in order to be guided through the recess 12 of the application 1 or the rod bead 2 in order to electrically contact them via the first electrical contact 20 and to robustly attach the rod bead 2 to the Textile element 80 to attach.

In 6 a schematic representation of a textile element 80 with a functional application 1 according to a further embodiment is shown. Here, on the left-hand side of the illustration, the textile element 80 is sewn to a first electrically conductive thread 82 and a second electrically conductive thread 84, with the first electrically conductive thread 82 and the second electrically conductive thread 84 crossing one another. At the crossing point 86 there is thus a short circuit between the two threads 82 , 84 . Due to the complexity of an electronic circuit made up of several functional applications 1, several electrically conductive threads 82, 84 often have to be guided or sewn along the textile element 80. It is often unavoidable that the electrically conductive threads 82, 84 cross. In order to avoid short circuits at the crossing points 86, a functional application 1 or a rod bead 2 can be attached to the textile element 80 in such a way that, for example, the first electrically conductive thread 82 is guided through the recess 12 of the rod bead 2 and the second electrically conductive thread 84 is guided over the outer surface 16, in particular over the constriction 7, of the rod bead 2. As a result, the two electrically conductive threads 82 , 84 are electrically separated from one another at the crossing point 86 .

In 7a to e a schematic representation of a method for attaching a functional application 1 to a textile element 80 is explained. In 7a In a first step, the functional application 1 embodied as a rod bead 2 is positioned on an upper side of the textile element 80 below a sewing needle 92 guiding an electrically conductive thread 82 . In 7b In a next step, the sewing needle 92 together with the electrically conductive thread 82 is inserted into the recess 12 of the rod bead 2 and the textile element 80 is pierced. The electrically conductive thread 82 is intertwined on an underside 80b of the textile element 80 and is thus mechanically connected to the textile element 80 . As in 7c shown, in a next step the sewing needle 92 together with the electrically conductive thread 82 is pulled out of the textile element 80 and the recess 12 again. In 7d it is shown how, in a next step, the rod bead 2 together with the electrically conductive thread 82 located in the recess 12 is folded over, and FIG 7e how the sewing needle 92, together with the electrically conductive thread 82, pierces the textile element 80 at a second position on the textile element 80. A distance between the second position and the first puncture point essentially corresponds to a length of the rod bead 2. The electrically conductive thread 82 is also intertwined at the second position on the underside 80b of the textile element 80 and is thus mechanically connected to the textile element 80. In a next step, the sewing needle 92 can be pulled out of the textile element 80 again and further sew the electrically conductive thread 82 to the textile element 80 to form an electrical conductor track on or in the textile element 80 . A mechanical connection to a further electrically conductive thread 84, and thus also a further electrical contact to the at least one further electrical contact 22 on the outer surface 16 of the rod bead 2, can take place in an analogous manner.

In 8th a flowchart of a method 100 for attaching a functional application 1 to a textile element 80 is shown. In a first step 101, the application 1 is provided and positioned on the textile element 80. In a further step 102, a first electrically conductive thread 82 is passed through the recess 12 of the carrier element 5. In a further step 103, the first is fastened electrically conductive thread 82 on the textile element 80 such that the first electrically conductive thread 82 electrically contacts the first electrical contact 20 . Optionally, in a further step 104, at least one further electrically conductive thread 84 is transferred over the outer surface 16 of the carrier element 5. Optionally, in a further step 105, the at least one further electrically conductive thread 84 is fastened to at least one area on the side of the outer surface 16, in particular on both sides of the outer surface 16, of the carrier element 5 on the textile element 80 in such a way that the at least one further electrically conductive thread 84 makes electrical contact with the at least one further electrical contact 22 of the carrier element 5 and that the first electrically conductive thread 82 and the at least one further electrical thread 84 are electrically separated.
