Description

Material member and vehicle seat

Technical Field

The utility model relates to a material member and a vehicle seat.

Background

Vehicle interiors and in particular seating furniture provided in motor vehicles are often equipped with one or more technical functions, for example adjustment functions. In particular, in the case of bad light, interior lighting is provided in motor vehicles in the vehicle interior and on the seats for sufficient orientation. Typically, the interior lighting is extinguished when the door is closed or when the engine is started. From this moment on, the operating elements of the lighting equipment with the individual light emitting diodes or the background make it easy to find them in space. Alternatively or additionally, the operating element can be illuminated at least indirectly by a light source mounted in a covering manner. In addition to the possible illumination of the footwell, it is also known to laterally delimit the interior by means of light sources arranged in the region of the door or/and the wall.

A method is known from WO 2013/49560 a1, which is directed to the integration of a light strip in a cover for a dashboard or a seat cushion. For this purpose, the two cutouts are connected to one another in the form of a slot, wherein a light strip for emitting light can be arranged on the rear side of the material component in the region of the slot in such a way that light energy of the light strip is at least partially detected through the slot from the front side of the material component opposite the rear side of the material component. In a specific embodiment, the light strip is formed by a laterally emitting optical conductor strand, wherein a light source, for example a light-emitting diode, is arranged at one of its ends.

In the case of a configuration of a cover for a motor vehicle seat, the optical conductor strand is used for the linear characteristic, which can be divided into individual segments by lines running through the optical conductor strand and/or by changes in the width of the slot. A regular spacing between the individual light sources is thus only possible at corresponding expense.

SUMMERY OF THE UTILITY MODEL

Against this background, the object of the utility model is to provide a material component which is suitable primarily for equipping vehicle interior components, furniture, saddles, clothing or motor vehicle seats, the configuration of the light strip provided in the region of the slot enabling a simpler realization of the light pattern to be produced.

To this end, the utility model proposes a material component, in particular a motor vehicle interior space component, having two cutouts which are connected to one another at least in some regions and form a slot, wherein a light strip which is designed to emit light is provided on a rear side of the material component, the light strip having light energy which is at least partially detectable through the slot from a front side of the material component opposite the rear side of the material component, characterized in that the light energy is at least partially detectable through gaps of the slot and the light strip has an at least partially electrically conductive carrier strip along which a plurality of individual light sources are arranged.

According to the utility model, the light strip is provided with an at least partially electrically conductive carrier strip, along which a plurality of individual light sources are arranged. In other words, the respective light patterns are now based on light sources which are separated from one another and are arranged at the respectively desired distance on the carrier strip. The light pattern thus obtainable no longer depends on the configuration of the slits, but only on the spacing of the individual light sources from one another. This enables a significantly simpler implementation when the desired light pattern is achieved.

According to a particularly preferred further development of the basic idea of the utility model, the individual light sources can be detachably coupled or/and couplable to the carrier strip. This means that the light sources can be individually arranged on and removed from the carrier strip. The carrier strip can advantageously be designed such that the light source coupled thereto already makes electrical contact with the carrier strip via its arrangement on the carrier strip. By means of the exchangeable arrangement of the individual light sources on the carrier strip, it is possible to obtain any desired light pattern in a "plug-in" like manner. Depending on the configuration, the light pattern is fixed here before the light strip is arranged on the rear side of the material element or can also be changed after said arrangement. In this way, the individual light sources can be supplemented or removed when required, for example on the basis of a fault. The configuration can also be selected such that the respective light source can be actuated through the slit and can thus be coupled to or removed from the carrier strip.

According to the utility model, the individual light sources can each be at least one light-emitting diode (LED). Such semiconductors have extremely small current requirements compared to their light intensity. Light-emitting diodes also achieve a high number of operating hours due to only a very small conversion of electrical energy into heat. Finally, the material of the cutouts is also protected, since it does not have to withstand the associated thermal loads due to the use of light-emitting diodes.

In principle, the light source is arranged in the region of the slot in such a way that it can be perceived at least partially through the gap of the slot. At least one or at least some of the light sources may be disposed at least partially inside the slot. This means that at least one of the light sources is arranged or can be arranged at least partially inside the gap of the slot. Depending on the position of the individual light sources relative to the slit, different effects can be achieved, which range from indirect, for example diffuse illumination to a pure point-by-point perception of the respective light source itself.

In a preferred manner, at least some of the light sources may be arranged at a distance from one another. By varying the spacing between the individual groups of light sources, a light pattern can be generated which consists of luminous and non-luminous strips. By spacing the individual light sources from one another, a light pattern in the form of a dot-dash line can be generated, which can be realized in a laterally emitting light guide without the individual segments having to be covered. In addition to a significantly simpler construction, this also enables a clearer boundary to be produced without any scattered light being produced.

A preferred spacing between two light sources may be, for example, 1 to 10 times the width of the respective light source extending in the direction of the slit. Alternatively, the distance may also correspond to 1 to 20 times the width of a light source. In principle, the light source can be a light source with a circular diameter, so that its dimensions in the direction of the slit and in the direction transverse to the slit are the same. Of course, a design of the light source with a rectangular cross section is also conceivable. By using other geometries for at least some of the light sources, for example triangular cross sections, it is possible to even indicate the direction of extension of the light strip, which can for example act as a reminder for a certain use case, for example in front or behind.

Within the scope of the present invention, different configurations of the slot are conceivable, which allow an integration or an arrangement of the light source in the sense according to the utility model.

The two cutouts can be at least partially sewn to one another by means of their edge sections facing one another by threads, wherein the first thread is guided through mutually opposite bending regions of the edge sections bent toward the rear side of the material element a plurality of times. The free projections of the edge sections facing away from each other are in this case each secured to the rear side of the material component by a line which is guided through the respective projection and the associated cutout a plurality of times. The carrier strip of the light strip is fixed on the rear side of the material component by the two lines for fixing the extension. Such a seam formation may also be referred to as a french seam.

The width of the carrier strip running transversely to its extent extends substantially parallel to the rear side of the material element, wherein the light sources of the carrier strip are arranged between the lines for fastening the extensions.

Alternatively, the first and second cutouts of the material element can be sewn to one another at least in regions by threads via their edge sections facing one another, wherein the first thread is guided through the mutually opposite bending regions of the edge sections of the two cutouts that are bent toward the rear side of the material element a plurality of times. The free extensions of the two edge sections, which are directed toward the first cutout, are then fixed to the rear side of the material part by means of second threads which are guided through the extensions and the first cutout several times. The carrier strip of the light strip is at least partially integrated between the free extensions of the two edge sections and is fixed by a second thread which fixes the extensions on the rear side of the material component. Such seam formation may also be referred to as an open or simple hem seam (kappanaht).

The widths of the carrier strip running transversely to its extent can be folded over one another and arranged between the two free projections of the edge section in such a way that its light source is located in the region of the slit. The orientation of the light source is dependent on the fold of the carrier strip, so that the light source can be oriented, for example, toward the gap of the slot or obliquely relative to the gap.

In principle, at least one of the light sources may be arranged below the gap of the slit, so that the light source is not located inside the gap, but only its light is emitted through the gap.

One embodiment of the arrangement of the light strip in the region of the slot shows the material component according to the utility model now provided, wherein a cover part may be preferred, which enables an extremely simple realization of the respective light pattern to be produced. In particular, the detachable, for example pluggable, arrangement of the individual light sources on the carrier strip of the light strip facilitates the generation of different light patterns many times. This can be achieved according to the configuration in that the corresponding light pattern can also be adapted and/or changed afterwards.

Furthermore, the utility model is also directed to a vehicle seat having a seat part and a back part connected to the seat part. The seat part or/and the back part/here is/are at least partially equipped with a material component according to the utility model. The advantages resulting therefrom have already been explained in connection with the description of the material component according to the utility model by way of further explanation, so that here it is intended to avoid repeated reference to corresponding embodiments. As far as the cover is concerned next, the described embodiments are correspondingly also suitable for use of the material arrangement according to the utility model for other use cases. In addition to the use of the material arrangement according to the utility model as a covering for a vehicle interior space arrangement (vehicle seat, vehicle seat part, vehicle seat backrest) or for furniture, the material arrangement according to the utility model is also considered, for example, for the outer material of a saddle or a garment. The outer material is a material which, in the intended use, is directed towards the outside of the object provided with the material member.

Detailed Description

Fig. 1 shows a light strip 1 for a material component according to the utility model (for example for a cover, for example a seat cover or parts thereof, not visible here further), having a carrier strip 2, in the longitudinal direction X of which individual light sources 3 are arranged. As can be seen from the symbol for the light sources 3, these are each embodied here purely by way of example as light-emitting diodes (LEDs). In order to ensure electrical contact, the carrier strip 2 here also has, purely by way of example, at least two electrically

conductive tracks

4a, 4b spaced apart from one another in parallel, wherein in each case one contact of the light source 3 is connected to in each case one electrically

conductive track

4a, 4 b. The light sources 3 are arranged in a detachable manner along the carrier strip 2 in such a way that they can be decoupled from the carrier strip if required, in a manner not described further, and can be coupled to the carrier strip in this case.

The couplability can be based on a corresponding plug connection in which the contacts of the light source 3 engage, for example, in recesses of the carrier strip 2. The recesses can be arranged in the region of the

conductive tracks

4a, 4b in such a way that the contacts of the light source 3 engaging in the recesses each forcibly contact one of the

conductive tracks

4a, 4b in order to be able to achieve the required current. The carrier strip 2 may be at least partially formed of fabric, wherein the voids may be formed by intersections of the fabric-forming threads and the electrically

conductive tracks

4a, 4 b.

The individual light sources 3 are arranged at a distance a from one another. With regard to the width B of the individual light sources 3 extending in the longitudinal direction X, the distance a here corresponds purely by way of example to 3 to 4 times the width B of the light sources 3.

Fig. 2 shows a section through the first configuration of the seam 5 of the cover part 6 according to the utility model. The cover 6 has two

cutouts

7, 8, which are connected to one another at least in some regions, forming the seam 5. The slot 5 is formed here as a french slot 5. The

edge sections

7a, 8a of the two

cutouts

7, 8 facing one another are sewn to one another at least in some regions by

threads

9, 10, 11. As can be seen, the two

edge sections

7a, 8a are bent away from each other toward the cover rear side 6 a. The first thread 9 is guided several times through mutually opposite bending regions C1, C2 of the

edge sections

7a, 8 a. Furthermore, the

free projections

7b, 8b of the

curved edge sections

7a, 8a facing away from each other are each fixed to the material component rear side 6a by means of a

line

10, 11 which is guided through the

respective projection

7b, 8b and the associated

cutout

7, 8a plurality of times. In particular, the first extension 7b of the first edge section 7a of the first cutout 7 is fixed to the material component rear side 6a by means of the second thread 10, while the second extension 7b of the second edge section 7a of the second cutout 8 is fixed to the material component rear side 6a by means of the third thread 11. The light strip 1 shown in fig. 1 and also visible here in section is also arranged here on the reference rear side 6a, wherein its carrier strip 2 is fixed to the material component rear side 6a by two

lines

10, 11 for fixing the

extensions

7b, 8 b.

In this way, the light sources 3 of the light strip 1 are arranged in the region of the slot 5 in such a way that their light, which can be emitted in the activated state, is at least partially detectable by the material component front side 6b opposite the material component rear side 6a through the gaps 12 of the slot 5.

Depending on the configuration, the light sources 3 or at least one of said light sources can be arranged at least partially here, as shown here, below the gap 12 of the slot 5 or, as not shown here, inside the gap 12 of the slot 5.

Fig. 3 shows an alternative configuration of the seam 5 of the cover 6 in the form of an open or simple hemming seam. As can be seen, the first thread 9 is also guided multiple times here through the bending regions C1, C2 of the

edge sections

7a, 8a of the two

cutouts

7, 8. In contrast to the french seam 5 of fig. 2, however, the two

free projections

7b, 8b are now jointly bent toward the first cutout 7, where they are jointly fastened to the material component rear side 6a by means of the second thread 10 which is guided through them and the first cutout 7 several times. In this case, the carrier strip 2 of the light strip 1 is now at least partially integrated between the two

free extensions

7b, 8b of the

edge sections

7a, 8a and is also fixed in this way on the material component rear side 6a by the second thread 10. For this purpose, the carrier strip 2 is folded correspondingly in its longitudinal direction X, wherein the light source 3 is arranged in the region of the slot 5.

The amount of light that can be emitted by the light source 3 can be adjusted correspondingly by the opening width of the gap 12 of the slit 5. Of course, it is also possible here to arrange at least some of the light sources 3 at least partially inside the gap 12.

Fig. 4 and 5 each show a plan view of the region of the cover 6. Fig. 4 shows the region of the slot 5 of fig. 2, while fig. 5 illustrates the region of the slot 5 of fig. 3. The difference is apparent in the third thread 11, which is not present in fig. 5, and which is present in fig. 4 as a configuration of the french seam 5. As is evident from the two plan views in fig. 4 and 5, the line 9 connects the two

cutouts

7, 8 only in sections, so that a recess 13 is produced between the sections, in which recess the light source 3 of the light strip 1 is arranged.
