Description

Assembly comprising a heating unit and a sensor unit, method for assembling such an assembly, seat comprising such an assembly and evaluation module field of technology

[0001] The present invention relates to an assembly comprising at least one heating unit for heating a surface within a vehicle, which surface can be brought into contact with a person, and at least one sensor unit, which is fastened to the heating unit in an assembled state of the assembly and is used to detect the presence of a person in the vicinity of and / or on the surface. The present invention also relates to a method for assembling such an assembly. Furthermore, the present invention relates to a seat for a vehicle comprising such an assembly. The present invention also relates to an evaluation module which is configured to evaluate a sensor signal from a sensor unit of such an assembly. State of the art

[0002] Motor vehicle seats often have a heating unit for warming a surface of the seat with which a person may come into contact. In addition, other separate units are often built into the seat. For example, a sensor unit can be used to detect the presence of a person on the seat.

[0003] The numerous units require increasingly larger installation space and a growing number of cable harnesses inside the seat. This leads to steadily increasing manufacturing costs for automotive seats. Furthermore, it must be ensured that the different units do not interfere with each other's functionality. Summary of the invention

[0004] It is therefore an object of the present invention to overcome the described disadvantages of the prior art and in particular to provide means by which heating and sensor units can be provided and operated within a seat in a simple yet reliable manner.

[0005] The object is achieved by the invention according to a first aspect in that an assembly comprising at least one heating unit for heating a surface within a vehicle, which surface can be brought into contact with a person, and at least one sensor unit attached to the heating unit in an assembled state of the assembly for detecting the presence of a person in the vicinity of and / or on the surface,

[0006] wherein the assembly in the assembled state has at least one fastening arrangement which is formed by at least one holding means provided on the heating unit and at least one holding section provided by the sensor unit, wherein in at least one specific cross-sectional plane the holding section is arranged at least partially between at least a part of the heating unit and the holding means.

[0007] The invention is therefore based on the surprising finding that a more reliable heating and monitoring of the surface of the vehicle is possible by positioning the heating and sensor units, which are conventionally provided independently of one another, in a defined manner relative to one another.

[0008] By attaching the sensor unit to the heating unit in the proposed assembly by at least one fastening arrangement, the relative positioning of the two units can be specified and maintained particularly reliably. This allows the tolerances existing with regard to the relative positioning of the two units to be reduced.

[0009] With smaller tolerances, the surface area heated or monitored by the units can be better defined. The sensor information provided by the sensor unit can therefore also represent a higher-quality database. This, in turn, allows the presence of a person on the seat to be detected more reliably.

[0010] Tighter tolerances also allow the heating area of ​​the heating unit to be extended further toward the sensor unit. This allows for better surface heating and avoids or at least reduces cold spots on the surface.

[0011] Tighter tolerances also allow for the electrical connections between the two units to be optimized, particularly by reducing their length. By making such connecting lines shorter, the proposed assembly saves material and thus reduces the cost and weight of the assembly.

[0012] Tighter tolerances also allow for at least partial use of shared cable harnesses for both units. This allows, for example, the power supply of one unit to be shared with the other unit in a simple yet reliable and safe manner. Duplicate cable harnesses can thus be avoided, at least in part. This also allows for material savings, and thus cost and weight savings. If fewer cable harnesses are required in a seat in which the assembly is advantageously installed, the openings for cable feedthroughs in the seat materials can also be reduced.

[0013] In particular, the proposed assembly can be installed in a vehicle seat. This is because any influences on the units resulting from a person's loading of the seat, which would traditionally cause the two units to shift relative to each other, can be reliably avoided or at least reduced.

[0014] Lower tolerances therefore enable more reliable operation of both units.

[0015] The proposed assembly can therefore represent a functional module for heating and monitoring the surface that can be brought into contact with the person.

[0016] The surface that can be brought into contact with the person can, for example, be a surface of a vehicle seat. Preferably, the assembly is installed in the seat whose surface can be brought into contact with a person.

[0017] For example, the sensor unit represents or includes a proximity sensor and / or pressure sensor. The proposed assembly then advantageously makes it particularly easy to combine seat heating with a seat belt reminder.

[0018] The at least one fastening arrangement at least partially secures the sensor unit to the heating unit. Preferably, the sensor unit can be secured to the heating unit without the use of adhesive.

[0019] Preferably, the sensor unit is non-destructively detachably attached to the heating unit in the assembled state. This advantageously allows the sensor unit to be transferred non-destructively from the assembled state to a non-assembled state, particularly in which the sensor unit is not attached to the heating unit.

[0020] In particular, the assembly can be transferred from an unassembled state to the assembled state, wherein in the assembled state the assembly has the fastening arrangement with the described arrangement of holding means and holding section.

[0021] Preferably, the retaining means is attached to the heating unit as a separate part. Alternatively, the retaining means is formed integrally with the heating unit. Preferably, the retaining means cannot be removed from the heating unit without causing damage. This reliably prevents the retaining means from becoming lost. This enables secure and reliable attachment of the sensor unit to the heating unit.

[0022] Preferably, the holding section is formed integrally with the sensor unit. This allows the holding section to be provided particularly easily and reliably.

[0023] Preferably, the specific cross-sectional plane intersects the fastening arrangement.

[0024] The heating unit is preferably able to be or is brought into heat-transferring connection with the surface to be heated.

[0025] Alternatively or additionally, it can also be provided that in the specific cross-sectional plane the holding section is arranged at least partially clamped between the at least one part of the heating unit and the holding means.

[0026] This allows the sensor unit to be held in a defined position on the heating unit simply yet reliably.

[0027] For example, the holding means and / or the heating unit can exert a clamping force on the holding section.

[0028] Alternatively or additionally, it can also be provided that, in the assembled state, the displaceability of the sensor unit relative to the heating unit in all three spatial directions is at least partially restricted by the fastening arrangement.

[0029] For example, the heating unit can be fixed within an installation volume (e.g., inside a seat). By restricting the sensor unit's mobility accordingly, a defined installation position within the installation volume can also be specified for the sensor unit.

[0030] Alternatively or additionally, it can also be provided that the heating unit has at least one flat first section and preferably the holding means is provided on the first section, in particular not removable without destruction.

[0031] In the present application, each section preferably has a specific thickness. The thickness is preferably measured along a direction parallel to the specific cross-sectional plane.

[0032] For example, the first section has a thickness of between 0.1 mm and 10 mm.

[0033] Preferably, in the sense of the present application, a section is formed flat if the section has a significantly larger (for example at least 3 times, 5 times or 10 times) extent in width and length than in thickness direction.

[0035] Preferably, the first carrier element is flat.

[0036] Optionally, the heating unit can also have electrical connections that can be connected, for example, to a power supply to supply the heating unit with electrical energy.

[0037] In one embodiment, the heating unit is designed, in particular at least partially, as a heating mat.

[0038] Alternatively or additionally, it can also be provided that the sensor unit has at least one flat second section and preferably the holding section is a part of the second section, in particular formed integrally with the sensor unit, in particular with the second section.

[0039] For example, the second section has a thickness of between 0.1 mm and 1 mm.

[0040] For example, the second section may be an arm-shaped section of the sensor unit.

[0041] For example, the sensor unit may comprise or form a capacitive sensor and / or pressure sensor.

[0042] Optionally, the sensor unit can also have electrical connections that can be connected, for example, to a power supply for supplying the sensor unit with electrical energy and / or via which sensor information can be transmitted. For example, the sensor unit can be electrically connected to the heating unit via electrical lines.

[0043] Alternatively or additionally, it can also be provided that the sensor unit has at least one second carrier element, such as at least one film element, and at least one sensor element, wherein preferably the sensor element has at least one conductor track structure, which is in particular at least partially arranged on the second carrier element.

[0048] Alternatively or additionally, it can also be provided that the second section has at least one convex or concave shaped end region.

[0049] By having a corresponding shape, the end region can be positioned particularly easily when attaching the sensor unit to the heating unit to form the fastening arrangement. In particular, this allows the end region to be guided through the retaining means more easily and securely, if this is required by a corresponding design of the retaining means, since any edges on the second section that could act as barbs can be easily and reliably avoided.

[0050] This makes the assembly and operation of the module safer.

[0051] Alternatively or additionally, it can also be provided that the second section has at least one, in particular lateral, recess in the region of the holding section, in which recess the holding means is guided at least in sections in the assembled state.

[0055] Preferably, in the context of this application, "lateral" is understood to mean a lateral side of the respective reference object (as opposed to a top side or a bottom side of the reference object), unless the context indicates otherwise.

[0056] Preferably, in the context of this application, a "lateral" recess of the second section is understood to mean a recess that is provided on a lateral side of the second section.

[0057] The recess is preferably part of the holding section.

[0058] For example, at least one transverse direction can be defined for the holding section, which, for example, points in the region of the holding section from one lateral side of the second section to the opposite lateral side of the second section. Preferably, the transverse direction perpendicular to the main extension of the second section and / or runs parallel to the specific cross-sectional plane.

[0059] In one embodiment, in the assembled state, the displaceability of the sensor unit relative to the heating unit can be restricted at least partially along a first spatial direction and / or a second spatial direction by an interaction of the recess and the holding means. In particular, the first spatial direction can be a spatial direction perpendicular to the specific cross-sectional plane, perpendicular to a surface normal of the heating unit and / or the holding section, and / or perpendicular to a transverse direction of the holding section. In particular, the second spatial direction can be a spatial direction parallel to the specific cross-sectional plane, perpendicular to a surface normal of the heating unit and / or the holding section, and / or parallel to a transverse direction of the holding section.

[0060] Alternatively or additionally, it can also be provided that at least one, in particular lateral, projection of the holding section is formed on the second section in the region of the holding section, and wherein at least one of the at least one recess is provided in the projection.

[0061] Preferably, the projection is a laterally protruding area of ​​the holding section.

[0062] For example, when looking at the second section, the projection may protrude laterally in a bulge-like manner.

[0063] Preferably, due to the projection, the second section in the region of the holding section has a greater width at least in sections, in particular in comparison to a width of a section of the second section following the holding section.

[0064] The second section preferably has an unchanged thickness in the area of ​​the projection as in the rest of the second section.

[0065] Alternatively or additionally, it can also be provided that the second section in the region of the holding section has at least two, in particular lateral, recesses, in which recess the holding means is guided at least in sections in the assembled state, and wherein preferably the two recesses are provided at opposite positions and / or on different lateral sides of the second section,

[0068] In one embodiment, the depth T is at least 0.1 mm, in particular at least 1 mm, in particular at least 3 mm, in particular at least 5 mm, in particular at least 7 mm

[0069] In one embodiment, the depth T is at most 10 mm, in particular at most 7 mm, in particular at most 5 mm, in particular at most 3 mm.

[0070] Alternatively or additionally, it can also be provided that a width B of the holding section measured at a height of the at least one recess, where it has its maximum depth, along a transverse direction running perpendicular to the main extension of the second section has a value of between 3 mm and 7 mm.

[0075] In one embodiment, the ratio B / T is at most 10, in particular at most 7, in particular at most 5.

[0076] Alternatively or additionally, it can also be provided that in the assembled state the holding means, in particular in the region of the holding section, extends at least in sections, in particular parallel to the specific cross-sectional plane and / or transversely, along a surface, in particular the upper side, of the second section.

[0077] The upper side is preferably characterized by a surface that points upwards during use of the assembly in a world coordinate system.

[0078] Preferably, the holding means thus extends in the region of the holding section at least in sections along a transverse direction over the second section.

[0079] As a result, in the assembled state, the displaceability of the sensor unit relative to the heating unit can be at least partially restricted at least along a third spatial direction. In particular, the third spatial direction can be a spatial direction parallel to the specific cross-sectional plane, parallel to a surface normal of the heating unit and / or the holding section, and / or perpendicular to a transverse direction of the holding section.

[0080] Alternatively or additionally, it can also be provided that, in order to at least partially transfer the assembly from an unassembled state to the assembled state, the holding section can be pushed, in particular along a direction perpendicular to the specific cross-sectional plane, between the heating unit, in particular the first section, and the holding means, preferably forming a spaced arrangement of at least a partial region of the holding means from the heating unit, in particular from the first section.

[0081] Alternatively or additionally, it can also be provided that in the assembled state an extension of the holding means, in particular within the specific cross-sectional plane, has at least one change in direction, in particular from an at least section-wise extension of the holding means along a first direction running parallel to a surface, in particular the upper side, of the holding section outside the recess to an at least section-wise extension of the holding means along a second direction with a component perpendicular to the first direction within the recess, wherein the second direction preferably points in the direction of the first section.

[0082] By means of a correspondingly selected course of the holding means, a force, in particular a clamping force, can be exerted on the holding section in the direction of the heating unit by means of the holding means in the assembled state.

[0083] By a correspondingly selected course of the holding means, the displaceability of the sensor unit relative to the heating unit can be restricted in the assembled state at least along the first and / or second spatial direction, advantageously along all three spatial directions, as already described above.

[0084] In particular, the holding means is guided at least in sections by the recess in a lateral region, in particular running parallel to the transverse direction.

[0085] Alternatively or additionally, it can also be provided that a course of the extension of the holding means when transferring the assembly from a non-assembled state to the assembled state is adjustable at least partially depending on the holding section, in particular at least partially depending on a thickness and / or width of the holding section.

[0086] For example, the adjustable course can be an adjustable position and / or strength of the previously described change in direction and / or an adjustable distance between the heating unit and the holding means.

[0087] Alternatively or additionally, it can also be provided that in the assembled state at least a portion of an edge of the holding portion, in particular in the region of the recess, is arranged along a direction perpendicular to a surface, in particular the upper side, of the holding portion above the holding means.

[0090] Alternatively or additionally, it can also be provided that the holding means is formed by at least one thread section of at least one thread, wherein preferably in the assembled state the thread section, in particular in the region of the holding section, runs at least in sections, in particular parallel to the specific cross-sectional plane and / or transversely, along a surface, in particular top side, of the second section, and wherein preferably the two ends of the thread section are fixed to the first section, in particular the two ends of the thread section, in particular in the assembled state, are fixed to the first section on different lateral sides of the holding section, in particular at the level of the respectively adjacent recess.

[0091] The use of a thread is particularly advantageous because the thread can be sewn on. Since this can be done mechanically and thus at least partially automated, providing a corresponding holding means on the heating unit is very simple yet reliable. For example, a heating element of the heating unit (such as a heating wire) could be arranged or attachable by sewing to the first support element of the heating unit. Then, both the heating element and the holding means could be arranged accordingly within a single sewing process.

[0092] Furthermore, sewing offers advantages over gluing, for example, in terms of speed and sustainability. This can make the production of the assembly and its components more cost-effective.

[0093] Preferably, the thread section runs above the holding section.

[0094] One end of the thread section can be fixed on one side laterally to the side of the holding section on the first section and the other end of the thread section can be fixed on the other side laterally to the side of the holding section on the first section.

[0095] For the purposes of this application, a thread is preferably understood to be a thin, long, and flexible structure, in particular a strand of textile material. A thread can, in particular, be a textile thread and / or a wire. For example, a thread can comprise at least one natural and / or at least one synthetic material. Examples of materials that a thread can comprise are cotton, silk, nylon, copper, steel, metal, and / or ceramic.

[0096] Alternatively or additionally, it can also be provided that the holding means is formed by a plurality of thread sections of at least one thread, wherein preferably in the assembled state the thread sections, in particular in the region of the holding section, each run at least in sections, in particular parallel to the specific cross-sectional plane and / or transversely, along a surface, in particular the top side, of the second section, and are preferably provided at least partially spaced from one another along the main extent of the second section, and wherein preferably the ends of the thread sections are fixed to the first section, in particular the two ends of each thread section, in particular in the assembled state, are each fixed to different lateral sides of the holding section, in particular at the level of the respectively adjacent recess, on the first section.

[0097] Preferably, a length of the holding means, in particular a single thread section, measured in particular along a direction parallel to (or directly in the specific cross-sectional plane), is between 0.5 times and 2 times, in particular between 0.6 times and 1.4 times, in particular between 0.8 times and 1.2 times, the smallest width of the holding section at the location of the holding means in the assembled state.

[0098] Alternatively or additionally, it can also be provided that immediately adjacent thread sections along the main extension of the second section have a distance from one another along the main extension of the second section of between 0.1 and 10 mm, in particular between 0.5 and 5 mm.

[0099] In one embodiment, the distance is at least 0.1 mm, in particular at least 1 mm, in particular at least 3 mm, in particular at least 5 mm, in particular at least 7 mm.

[0100] In one embodiment, the distance is at most 10 mm, in particular at most 7 mm, in particular at most 5 mm, in particular at most 3 mm.

[0101] Alternatively or additionally, it can also be provided that the plurality of thread sections are arranged along a section length of between 1 mm and 10 mm along the main extension of the second section.

[0102] In one embodiment, the section length is at least 1 mm, in particular at least 3 mm, in particular at least 5 mm, in particular at least 7 mm.

[0103] In one embodiment, the section length is at most 10 mm, in particular at most 7 mm, in particular at most 5 mm, in particular at most 3 mm.

[0104] Alternatively or additionally, it can also be provided that the plurality of thread sections are formed by a single thread with realization of at least one change of direction, in particular a 180° change of direction and / or a 90° change of direction, of the running direction of the thread.

[0105] This makes it particularly easy to manufacture the retaining means. Only a single thread needs to be provided on the first section, in particular, sewn to it. The retaining means can thus advantageously be attached and / or formed to the first section by machine.

[0106] Alternatively or additionally, it can also be provided that in at least one direction change region of the thread, in which a change in the running direction of the thread is realized, one or more auxiliary seams are provided, with which the end of at least one thread section, preferably the ends of at least two thread sections, of the thread is fixed to the first section in the direction change region.

[0107] This allows the holding means to be provided very simply yet reliably on the first section. For example, the single thread can be laid on the first section, perhaps forming a serpentine pattern and / or mechanically, and the auxiliary seams for securing the thread—and thus the ends of the respective thread sections—can be applied to the first section in the direction change areas, particularly mechanically.

[0108] For example, between 2 and 10, preferably between 3 and 4, auxiliary seams can be provided in each direction change area.

[0109] Alternatively or additionally, it can also be provided that the thread runs at least once through the first section.

[0110] Preferably, the thread passes through the first section at least twice.

[0111] For example, this state can be achieved by the thread passing through the first section at least once, preferably at least twice, by means of a stitch during a sewing process.

[0112] This allows a particularly reliable fixation of the thread to the first section.

[0113] Preferably, in the sense of this application, a thread runs through a (in particular first / second) section when the introduction of the thread into the section is carried out with at least partial and / or at least regional displacement and / or removal of the material of the respective section.

[0114] Alternatively or additionally, it may also be provided that the thread does not run through the second section.

[0115] This allows the heating unit to be manufactured separately from the sensor unit, which can increase the modularity of the assembly and / or reduce manufacturing costs.

[0116] In addition, this makes it particularly advantageous to achieve non-destructive detachability of the sensor unit from the heating unit.

[0117] Alternatively or additionally, it can also be provided that at least one thread section has a length which is greater than the smallest width of the second section in the region of the holding section.

[0118] This allows reliable positioning of the sensor unit to be achieved.

[0119] In one embodiment, all thread sections have a corresponding length.

[0120] Preferably, the length is measured along a direction parallel to the specific cross-sectional plane.

[0121] Alternatively or additionally, it can also be provided that at least one thread section has a length which is smaller than the greatest width of the second section in the region of the holding section, in particular in the region of its projection.

[0122] This allows for reliable positioning of the sensor unit, as it can reliably prevent the holding section from accidentally detaching from the holding means.

[0123] In one embodiment, all thread sections have a corresponding length.

[0124] Preferably, the length is measured along a direction parallel to the specific cross-sectional plane.

[0125] Alternatively or additionally, it can also be provided that the holding means is formed by at least one material strip, wherein preferably in the assembled state the material strip, in particular in the region of the holding section, runs at least in sections, in particular parallel to the specific cross-sectional plane and / or transversely, along a surface, in particular top side, of the second section, and wherein preferably the two ends of the material strip are fixed to the first section, in particular the two ends of the material strip, in particular in the assembled state, are fixed to the first section on different lateral sides of the holding section, in particular at the level of the respectively adjacent recess.

[0126] The material strip can be fixed to the first section, for example, by sewing, gluing and / or welding the material strip.

[0127] Alternatively or additionally, it can also be provided that at least one blocking element is formed on the second section in an area adjacent to the holding section, and in the assembled state, the holding means is arranged at least partially adjacent to the blocking element and thereby a displaceability of the sensor unit relative to the heating unit along at least one direction is blocked,

[0128] wherein the blocking element is preferably formed by at least one, preferably two, in particular lateral, projections of the second section, and wherein the two projections are preferably formed at opposite positions and / or on different lateral sides of the second section.

[0129] For example, the blocked direction can be perpendicular to the specific cross-sectional plane.

[0130] In one embodiment, the assembly in the assembled state may have at least one further fastening arrangement, the holding means of which is arranged adjacent to a further blocking element.

[0131] In one embodiment, the assembly in the assembled state may have at least one further fastening arrangement whose holding means is not arranged adjacent to a blocking element.

[0132] Alternatively or additionally, it can also be provided that the module in the assembled state has a plurality of fastening arrangements, in particular of similar construction, wherein preferably each of the fastening arrangements is at least one holding means provided on the heating unit and at least one holding section provided by the sensor unit are formed, and in at least one specific cross-sectional plane, the respective holding section is arranged at least partially between the heating unit and the respective holding means,

[0133] and wherein preferably the plurality of fastening arrangements predetermines a permissible fastening of the sensor unit to the heating unit according to the Poka Yoke principle.

[0134] For this purpose, a plurality of holding means are preferably provided on the heating unit, and a plurality of holding sections are provided by the sensor unit. The individual fastening arrangements are then formed by at least one of the holding means, in particular exclusively, and at least one of the holding sections, in particular exclusively, wherein in at least one specific cross-sectional plane, the respective holding section is arranged at least partially between the heating unit and the respective holding means. "Exclusive" means that the respective holding means or the respective holding section contributes only to a single fastening arrangement of the plurality of fastening arrangements.

[0135] For example, the sensor unit may have a plurality of second sections, and at least two, preferably all, of the holding sections provided by the sensor unit are part of different second sections. In one embodiment, two or more than two holding sections provided by the sensor unit are part of an identical second section. In this case, the holding sections may be spaced apart from one another, in particular along a main extension of the respective second section.

[0136] For each fastening arrangement, an individual, specific cross-sectional plane is preferably defined. The previous references to the (single) specific cross-sectional plane then apply accordingly to the individual specific cross-sectional planes in connection with the respective fastening arrangement.

[0137] Due to the Poka Yoke principle, only a single alignment (in particular position, location and / or orientation) of the sensor unit relative to the heating unit is possible, so that a preferred alignment of the sensor unit relative to the heating unit can be specified particularly easily.

[0138] Preferably, the second sections in the region of at least two holding sections of different fastening arrangements of the plurality of fastening arrangements each have a recess on only one lateral side. In this case, it is advantageous if the openings of at least two of these recesses, each provided on only one side, point in different, preferably opposite, directions.

Description of the embodiments

[0151] Fig. 1a shows a schematic representation of an assembly 1 according to the first aspect of the invention in a first embodiment, in a plan view. Fig. 1b shows a sectional view of the assembly from Fig. 1a, wherein the section runs perpendicular to the plane of the drawing of Fig. 1a along the line S and the viewing direction is parallel to the direction R.

[0152] The assembly 1 has a heating unit 3 with which a surface within a vehicle, which surface can be brought into contact with a person, can be heated.

[0153] Fig. 2a shows a schematic representation of the heating unit 3 in a top view. Fig. 2b shows a cross-sectional view of the heating unit 3 from Fig. 2a, with the section running perpendicular to the plane of the drawing of Fig. 2a along the line QS.

[0154] The heating unit 3 can, for example, be designed as a heating mat. In this case, the heating unit 3 can have a first support element 5 (for example, a fleece element) and a heating element (not shown in Fig. 2a), such as a heating wire, arranged on the first support element.

[0155] The heating unit 3 has a flat first section 7. This first section 7 corresponds to the part of the first carrier element 5 shown in Fig. 2a. A holding means 9 is provided on the first section 7, which is formed by several, in the present case, for example, five, thread sections 11 of a thread 13. The thread 13 is laid on the first section 7 in a loop-like manner with several 180° changes in the running direction of the thread 13. The ends 15 of the thread sections 11 are fixed in regions 17 on the first section 7. This results in several thread sections 11 running parallel to one another and spaced apart from one another along the Y-direction. In the respective regions 17, in each of which If the direction of travel of the thread is changed, the ends 15 of the thread sections are fixed to the first section, for example by several auxiliary seams.

[0156] The holding means 9 can therefore only be detached from the first section 7 by opening the auxiliary seams and thus not without destruction.

[0157] From the cross-sectional view of Fig. 2b, it can be seen that the thread section 11 shown therein (as well as the other thread sections of the holding means) lies loosely on a surface 19 of the first section 7 and that its ends 15 are fixed in the regions 17 on the first section 7. The air gap visible in Fig. 2b between the first section 7 and the thread section 11 is shown merely to better identify the individual elements.

[0158] With regard to the holding means 9, for the sake of clarity, only one of the features in Figs. 1a, 1b, 2a and 2b is provided with a reference symbol for features that occur frequently (such as the multiple thread sections 11 or their ends 15).

[0159] In addition, the assembly 1 has a sensor unit 21 with which the presence of a person in the vicinity and / or on the surface (which can be heated by the heating unit) can be detected.

[0160] Fig. 3 shows a schematic representation of the sensor unit 21 in a plan view.

[0161] The sensor unit 21 can, for example, have a second carrier element 23 in the form of a film element. The second carrier element 23 can be flexible and thus curved. A sensor element 25 in the form of several conductor track structures is arranged on the second carrier element 23. Furthermore, the sensor unit 21 has various electronic components in a component area 27. The component area 27 is firmly connected to the second carrier element. The sensor unit 21 thus forms a capacitive proximity sensor.

[0162] The sensor unit 21 has a flat second section 29 with an elongated extension along the Y-direction. This second section 29 corresponds to the part of the second support element 23 shown in Fig. 3a, but could only be a part of it. As a part formed integrally with the second section 29, the sensor unit 21 provides a holding section 31. In other words, the holding section 31 is a partial section of the second section 29.

[0163] The second section 29 has, in the region of the holding section 31, two lateral projections 33, which are part of the holding section 31. These projections 33 are formed on different lateral sides of the second section 29 and at opposite positions of the second section 29. In each projection 33, a lateral recess 35 of the second section 29 is provided. The openings 37 of the two lateral recesses 35 point in opposite directions. The recesses 35 are oval-shaped. The holding section 31 is thus formed symmetrically to a central axis of the second section 29. Therefore, for the sake of clarity, only one of the features that occur equally on both lateral sides of the second section is provided with a reference symbol in Figs. 1a, 1b, and 3.

[0164] The maximum depth of the two recesses 35 is, for example, 5 mm each. The maximum depth is measured along the dashed line shown in Fig. 3 for orientation. The measuring section runs along a transverse direction (X direction) that is perpendicular to the main extension (Y direction) of the second section 29.

[0165] Where the two recesses 33 have their maximum depth (and thus in this case the holding section 31 has its smallest width), the width of the holding section 31 is, for example, 14 mm.

[0166] In another embodiment, the holding section 31 could also have only one of the two lateral projections 33 and thus only a single recess 35.

[0167] In another embodiment, the recesses 35 could be rectangular instead of oval.

[0168] The heating unit 3 shown separately in Fig. 2a and Fig. 2b and the sensor unit 21 shown separately in Fig. 3 are components of the assembly 1 shown in Fig. 1a in an assembled state. In an assembled state of the assembly 1, the sensor unit 21 is fastened to the heating unit 3 by means of a fastening arrangement 39 of the assembly 1.

[0169] As can be seen in particular from the sectional view of Fig. 1b, the fastening arrangement 39 is formed by the holding means 9 and the holding section 31. In a specific cross-sectional plane intersecting the fastening arrangement 39, which in this case is the drawing plane of Fig. 1b, the holding section 31 is arranged at least partially between the heating unit 3, in particular the first section 7, and the holding means 9.

[0170] The holding means 9 (in this case, the thread sections 11) extends in the region of the holding section 31 transversely along a surface 41 of the second section 29, which in Figs. 1a and 1b represents an upper side of the second section 29. This surface 41 is simultaneously a surface of the holding section 31.

[0171] Due to the fastening arrangement, in the assembled state, the displaceability of the sensor unit 21 relative to the heating unit 3 in all three spatial directions is restricted.

[0172] No matter in which of the three spatial directions X, Y and Z the sensor unit 21 is moved relative to the heating unit 3, the holding means 9 (here the thread sections 11) restricts The displaceability of the holding section 31, and thus the displaceability of the entire sensor unit 21, is accordingly limited. In other words, the threads of the thread sections 11 prevent the relative displaceability of the holding section 31.

[0173] If, for example, the heating unit 3 is stationary, the holding means 9 restricts the displaceability of the sensor unit 21 relative to the stationary heating unit 3, in particular along a direction parallel (and antiparallel) to the X-axis (thus to the right or left in Fig. 1a), along a direction parallel (and antiparallel) to the Y-axis (thus up or down in Fig. 1a) and along a direction parallel to the Z-axis (thus in Fig. 1a in the direction of the observer).

[0174] In particular, displaceability is limited at least along a direction parallel (and antiparallel) to the X-axis and along a direction parallel (and antiparallel) to the Y-axis by an interaction between the holding means 9 and the two recesses 33. This is achieved in that, in the assembled state, the holding means 9 in the form of the thread sections 11 is guided at least partially in the two recesses 35. This, in turn, is achieved in that the extension of the holding means 9 has a change in direction in the region of the recesses 35. Namely, from a course of the holding means 9 along a (first) direction parallel to the surface of the holding section 31 (i.e., approximately parallel to the X-axis) to an extension of the holding means 9 along a (second) direction with a component perpendicular to the first direction. Specifically, the second direction points in the direction of the first section 7.

[0175] Since the two ends 15 of each thread section 11 are each fixed 7 to the first section on different lateral sides of the holding section 31 in the assembled state, the change of direction can be achieved very easily by forcing the thread sections upwards at least in a central region through the holding section 31 and thereby arranging them there at a distance from the first section 7.

[0176] As can be seen from the sectional view of Fig. 1b, in the assembled state, a portion of an edge 43 of the holding portion 31 is arranged in the region of the recess 35 along the Z direction above the holding means 9. Thus, when the thread portions 11 abut a (particularly inner) surface 45 of the recess 35 during a displacement of the sensor unit 21 relative to the heating unit 3 along the Y direction, further displacement of the sensor unit 21 along the Y direction is restricted.

[0177] In addition, the ability to move at least along a direction parallel (and antiparallel) to the X-direction is also limited by the interaction between the holding means 9 and the holding section 31. Because of the selected course of the holding means 9 in the assembled state, especially in the area of ​​the recesses 35, the Thread sections 11 allow the holding section 31 to be displaced in the region of the recess 35, as can also be seen from Fig. lb.

[0178] The sensor unit 21 can therefore be easily attached to the heating unit 3 by sliding the holding section 31 (from below in Fig. 1a) along the Y direction between the first section 7 and the holding means 9. This is facilitated by the fact that the second section 29 has a convexly shaped end region 47. The convex shape of the end region 47 of the second section 7 allows particularly reliable insertion of the second section 7 between the first section 7 and the holding means 9. Furthermore, the upper regions of the projections 33 acting as shoulders 49 facilitate the secure guidance of the holding means 9 along the projections 33 (possibly by stretching the holding means 9 and / or by curving the second section 29) until the holding means 9 is guided in the recesses 35 as described. Further relative displacement is then limited, as explained.

[0179] Adjacent thread sections 11 of the present five thread sections 11 are spaced apart by 1 mm along the main extension of the second section (Fig. 1a; Y-direction) and thus extend along a section length of 5 mm. The individual thread sections 11 each have a length that is greater than the smallest width of the second section 29 in the region of the holding section 31.

[0180] In this way, the sensor unit 21 is non-destructively detachably attached to the heating unit 3 by means of the fastening arrangement 39. To detach the sensor unit 21 from the heating unit 3, for example, the sensor unit 21 can be curved in the region of the second section 29 and / or the holding means 9 can be manually stretched so that the holding section 31 can be removed from the effective range of the holding means 9.

[0181] Fig. 4 shows a schematic representation of an assembly 1' according to the first aspect of the invention in a second embodiment in a plan view.

[0182] The assembly 1' of the second embodiment is constructed similarly to the assembly 1 of the first embodiment (Figs. 1a, 1b). Therefore, identical features are provided with identical, but single-primed, reference numerals. For this reason, only the differences between the assembly 1' of the second embodiment and the assembly 1 of the first embodiment need be described.

[0183] In the assembly 1' of the second embodiment, the holding means 9' is formed by a material strip 51'. The two ends 15' of the material strip are each fixed to the first section 7' ​​in the regions 17' on different lateral sides of the holding section 31'.

[0184] Fig. 5 shows a schematic representation of an assembly 1" according to the first aspect of the invention in a third embodiment in a plan view.

[0185] In the assembly 1" of the third embodiment, features that are the same as those of the assembly 1 of the first embodiment are provided with the same reference numerals, but with double primes. Only the differences between the assembly 1" of the third embodiment and the assembly 1 of the first embodiment will be described below.

[0186] In the assembly 1" of the third embodiment, the second section 29" in the region of the holding section 31" has no lateral projections (like the projections 33 in the first embodiment or projections 33' in the second embodiment) and no recesses (like the recesses 35 in the first embodiment or recesses 35' in the second embodiment). Accordingly, the holding means 9", which in the third embodiment is designed in the form of thread sections 11", entirely in accordance with the first embodiment, is also not guided in recesses. Instead, it runs transversely along the second section along the surface 41" of the holding section 31".

[0187] Thus, the assembly 1" of the third embodiment forms a fastening arrangement 39" with the holding means 9" and the correspondingly modified holding section 31".

[0188] In the assembly 1" of the third embodiment, however, a blocking element 53" is formed on the second section 29" in a region adjacent to the holding section 31" (in Fig. 5 in the Y direction below the holding section 31").

[0189] In the assembled state of the assembly 1" shown in Fig. 5, the holding means 9" is arranged at least partially adjacent to the blocking element 53". This blocks the displaceability of the sensor unit 21" relative to the heating unit 3" along at least the positive Y-direction.

[0190] The blocking element 53" is formed by two lateral projections 55" of the second section 29". The two projections 55" are formed at opposite positions and on different lateral sides of the second section 29" (in Fig. 5, "left and right").

[0191] In another embodiment, the assembly 1" could have a further fastening arrangement, wherein the further fastening arrangement could be designed like the fastening arrangement 39" of the third embodiment, like the fastening arrangement 39' of the second embodiment, or like the fastening arrangement 39 of the first embodiment. The further fastening arrangement could, for example, be provided offset from the fastening arrangement 39" along the second section 29" (for example, in Fig. 5 is offset upwards along the Y-direction). The retaining means of the additional fastening arrangement would preferably not be arranged adjacent to a (further) blocking element in the assembled state. The additional fastening arrangement could make the attachment of the sensor unit 21" to the heating unit 3" more reliable.

[0192] Fig. 6 shows a schematic representation of an assembly according to the first aspect of the invention in a fourth embodiment in a plan view.

[0193] The assembly 1"' of the fourth embodiment is constructed similarly to the assembly 1 of the first embodiment (Figs. 1a, 1b). Therefore, identical features are provided with the same, but triple-primed reference numerals. And for this reason, only the differences between the assembly 1"' of the fourth embodiment and the assembly 1 of the first embodiment need be described.

[0194] Three holding means 9"' are provided on the heating unit 3"'. Each holding means 9"' is designed in the form of several thread sections, like the (single) holding means 9 of the first embodiment. The individual details of the holding means 9"' are not provided with reference numerals in Fig. 6 for the sake of clarity. Instead, reference can be made to the illustration in the corresponding figures of the first embodiment.

[0195] The three holding means 9"' are therefore three groups of thread sections, each group of thread sections being formed by a thread. Alternatively, the three groups of thread sections could also be formed by a single thread.

[0196] The sensor unit 21"' has three second sections 29"'. A holding section 31'" is provided on each second section 29'". Each holding section 31'" is designed like the (single) holding section 31 of the first embodiment. The individual details of the holding section 31'" are not provided with reference numerals in Fig. 6 for the sake of clarity. Instead, reference can be made to the illustration in the corresponding figures of the first embodiment.

[0197] The sensor unit 21'" thus has, in the assembled state, three identically constructed fastening arrangements 39'". For each fastening arrangement 39'", a separate specific cross-sectional plane is defined, which runs perpendicular to the drawing plane of Fig. 6 along the respective line S'". In each of these specific cross-sectional planes, the holding section of the respective fastening arrangement 39'" is arranged at least partially between the first section 7'" and the holding means of the respective fastening arrangement 39'".

[0198] Due to the plurality of fastening arrangements 39'" in the assembly 1'" of the fourth embodiment, here three fastening arrangements 39'", a permissible fastening of the sensor unit 21'" to the heating unit 3'" according to the Poka Yoke principle is specified. If the Sensor unit 21"' is rotated (in the plane of the drawing in Fig. 6), there is no second position in which the sensor unit 21"' can be attached to the heating unit 3"".

[0199] Fig. 7 shows a flowchart of a method according to the second aspect of the invention.

[0200] The method enables the reliable assembly of an assembly comprising at least one heating unit, on which at least one holding means is provided, and at least one sensor unit, which provides at least one holding section. For example, this can be an assembly according to the first aspect of the invention, such as assembly 1 of the first embodiment, assembly 1' of the second embodiment, assembly 1" of the third embodiment, or assembly 1'" of the fourth embodiment.

[0201] In 101, the heating unit and the sensor unit are provided for this purpose.

[0202] In 103, the sensor unit is attached to the heating unit by forming at least one fastening arrangement. The fastening arrangement is designed such that, in at least one specific cross-sectional plane, the holding section is arranged at least partially between at least a portion of the heating unit and the holding means.

[0203] Fig. 8 shows a schematic representation of a seat 201 according to the third aspect of the invention in a cross-sectional view.

[0204] The seat 201 has a base 203 and a back 205. Within the seat 201, in particular within the base 203, an assembly 207 according to the first aspect of the invention is provided. This can, for example, be one of the assemblies 1, 1', 1", or 1'" described above. The heating unit of the assembly 207 can heat a surface 209 of the seat 201. Furthermore, the sensor unit of the assembly 207 can detect the presence of a person near (and also on) the surface 209.

[0205] Fig. 9 shows a schematic representation of an evaluation module 211 according to the fourth aspect of the invention.

[0206] The evaluation module 211 is configured to evaluate a status signal II (as a first input variable) of a safety belt of a motor vehicle and a sensor signal I2 (as a second input variable) of a sensor unit of an assembly installed in the motor vehicle according to the first aspect of the invention and to generate a result signal O (as an output variable) which is indicative of the fact that a person at least partially detected as being present by means of the sensor unit has not yet properly fastened the safety belt.
