Description

[0001] The invention relates to a covering arrangement for an interior component of a vehicle, according to the preamble of patent claim 1.

[0002] Cover arrangements or covers for interior components are available in numerous variations. These cover arrangements or covers feature a textile with a predefined structure or color.

[0003] In addition, textiles are known that vary their mesh size, reflectivity, and transmittance for infrared radiation depending on changes in temperature or humidity. This allows the textiles to change their insulating properties or their permeability to heat and moisture depending on temperature or humidity.

[0004] DE 20 2018 004 272 U1 discloses a covering arrangement for an interior component, wherein the covering arrangement corresponds to a seat cover and the interior component to a vehicle seat. The seat cover comprises a nonwoven structure with a first layer of a fiber composite and a second layer of a fiber composite. The first and second layers are arranged consecutively in a thickness direction perpendicular to the transverse direction and the longitudinal direction of the nonwoven structure. The first and second layers are connected to one another in at least two connecting regions by mechanical consolidation of the fiber composites. Relative to the longitudinal direction of the nonwoven structure, at least in sections, the at least two connecting regions each have a width of at most 5 cm in the transverse direction of the nonwoven structure. In addition, the at least two connecting regions are spaced from one another by at least 1 cm.

[0005] From "UMD RIGHT NOW," a University of Maryland journal dated February 7, 2019, a textile is known which is made up of at least one yarn with multiple fibers. The fibers comprise two different synthetic materials, a first material which absorbs water and a second material which repels water. The two materials are enclosed in carbon nanotubes. When the temperature or humidity increases, the fibers of the yarn lie more closely together than when the temperature or humidity decreases. This increases the mesh size of the textile. When the temperature or humidity decreases, the fibers of the yarn lie more loosely together, reducing the mesh size of the textile. In addition, the bandwidth of the infrared radiation which is reflected or transmitted by the carbon nanotubes is shifted.At a given first temperature or humidity, wavelengths of infrared radiation corresponding to a person's resting body temperature are transmitted. At a given second temperature, which is lower than the first temperature, wavelengths of infrared radiation corresponding to a person's resting body temperature are reflected. The textiles are suitable for the production of clothing.

[0006] DE 697 17 721 T2 discloses a knitted cover for a vehicle seat. The cover has a section that can change its shape if the cover undergoes heat treatment prior to installation of the vehicle seat. The section has an identification tab or a label knitted integrally with the cover, which acts as a visual and tangible indicator to indicate when the cover has undergone heat treatment.

[0007] DE 101 02 111 A1 discloses a process for producing three-dimensional components with either a uniform or variable height and / or curvature. This effect is achieved through the use of spacer fabrics or spacer knits in conjunction with special yarns that shrink under the influence of heat. By partially or completely applying covering materials before shrinking, even finished products with complex shapes can be provided with the appropriate coverings. This can be achieved, for example, by coating or gluing the flat blanks. After shrinking, the finished product is covered with the covering without any additional processing steps. Due to the structure of individual, intertwined fibers or threads, a component of this type can be further processed or joined using conventional textile industry processes.

[0008] DE 20 2011 004 899 U1 discloses a motor vehicle interior trim component consisting essentially of plastic. At least a portion of the surface of the interior trim component can be heated to a controllable temperature.

[0009] DE 603 ​​09 814 T2 discloses a shielding device that discloses a generic covering arrangement for an interior component of a vehicle. The covering arrangement comprises a textile formed from at least one yarn with multiple fibers, wherein at least one property of the textile can be specifically changed during use by changing the temperature and / or humidity.

[0010] The invention is based on the object of providing a covering arrangement for an interior component of a vehicle, which can be adapted to an ambient temperature or to an ambient humidity.

[0011] This object is achieved by a covering arrangement for an interior component of a vehicle having the features of patent claim 1. Advantageous embodiments with expedient further developments of the invention are specified in the dependent patent claims.

[0012] In order to provide a covering arrangement for an interior component of a vehicle which is adaptable to an ambient temperature or to an ambient humidity, at least one property of the textile can be specifically changed by means of a change in temperature and / or humidity.

[0013] A covering arrangement for an interior component of a vehicle is understood below to mean an assembly comprising at least one textile. The textile is formed from at least one yarn with multiple fibers. The textile can be woven, knitted, or crocheted. Furthermore, the textile can have connecting areas that are connected to the interior component. Additionally or alternatively, a fastening arrangement can releasably or permanently attach the textile to the interior component.

[0014] In the following, an interior component is understood to mean a vehicle seat and / or an armrest and / or a steering wheel and / or a door panel and / or a vehicle headliner.

[0015] By altering at least one property of the textile as a function of temperature and / or humidity changes, comfort for vehicle occupants or protection for the interior component can be advantageously improved. To ensure that an occupant feels comfortable in warm or hot temperatures and high humidity, for example, a different insulating capacity or permeability of the textile is specified than in cold temperatures and low humidity. Furthermore, a different insulating capacity or permeability of the textile is specified in warm or hot temperatures and high humidity than in cold temperatures and low humidity, so that the interior component is better protected.

[0016] In an advantageous embodiment of the covering arrangement according to the invention, the fibers of the at least one yarn can change a mesh size of the textile depending on the change in temperature and / or depending on the change in air humidity. In this case, the mesh size can be increased when the outside temperature or air humidity increases and reduced when the outside temperature and air humidity decrease. The larger mesh size allows heat or moisture to be dissipated more quickly and improves the breathability of the covering arrangement according to the invention. For example, the body heat and perspiration of the occupant who is in contact with the interior component having the covering arrangement according to the invention can be transported away from the occupant more quickly due to the large mesh size of the textile.As temperatures drop, the mesh size is advantageously reduced, thereby improving the insulating properties of the fabric. This allows the occupant's body heat to be better retained, providing a beneficial warming effect even without additional technical means.

[0017] In a further advantageous embodiment of the covering arrangement according to the invention, the fibers of the at least one yarn can contract with increasing temperature and / or increasing air humidity and can be arranged more tightly in the yarn, thereby increasing the mesh size of the textile. This advantageously improves the breathability of the textile and thus achieves better ventilation. The fibers of the textile can be heated by the body heat of the occupant and by the temperature in the vehicle. In addition, a heater in the interior component can heat the fibers of the textile. For example, the heat from a vehicle seat heater can advantageously be transported more quickly and effectively to the occupant sitting on the corresponding vehicle seat by increasing the mesh size.

[0018] In a further advantageous embodiment of the covering arrangement according to the invention, the fibers can be arranged more loosely in the yarn as the temperature and / or humidity decrease, thereby reducing the mesh size of the textile. This advantageously improves the insulating properties of the textile and thus better retains existing heat. At a cool temperature in the vehicle, an occupant who is in contact with the interior component can be better warmed by the textile.

[0019] In a further advantageous embodiment of the coating arrangement according to the invention, the fibers can comprise infrared-active carbon nanotubes. The carbon nanotubes can enclose several different synthetic materials that comprise the individual fibers. Furthermore, carbon nanotubes are transparent to infrared radiation with a predetermined first wavelength and reflect infrared radiation with a predetermined second wavelength.

[0020] In a further advantageous embodiment of the covering arrangement according to the invention, the wavelength of the infrared radiation to which the carbon nanotubes are permeable or which the carbon nanotubes reflect can depend on the condition of the fibers. In this case, if the fibers are tightly packed together in the yarn, the carbon nanotubes can transmit infrared radiation with a wavelength that corresponds to the body temperature of the occupant. This can advantageously further improve the breathability of the textile and thus achieve better ventilation. In this case, if the fibers are loosely packed together in the yarn, the carbon nanotubes can reflect infrared radiation with a wavelength that corresponds to the body temperature of the occupant. This can advantageously further improve the insulating capacity of the textile and thus achieve better warming of the occupant.

[0021] In a further advantageous embodiment of the covering arrangement according to the invention, the condition of the fibers and the mesh size of the textile can be influenced by applying current to the carbon nanotubes. This allows the insulating and breathability of the textile to be actively adapted to the current conditions in the vehicle and the needs of the occupant.

[0022] The features and feature combinations mentioned above in the description, as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figures, can be used not only in the respective combinations specified, but also in other combinations or on their own, without departing from the scope of the invention. Thus, embodiments are also to be considered encompassed and disclosed by the invention that are not explicitly shown or explained in the figures, but which emerge and can be produced from the explained embodiments through separate feature combinations.

[0023] An embodiment of the invention is illustrated in the drawing and explained in more detail in the following description. In the drawing, like reference numerals designate components or elements that perform the same or similar functions. Herein: Fig. 1 is a schematic block diagram of an embodiment of a coating arrangement according to the invention; Fig. 2 an enlarged section of the textile of the cover arrangement according to the invention from Fig. 1 with at least one yarn in a taut state; Fig. 3 a schematic perspective sectional view of the yarn of the textile from Fig. 2; Fig. 4 an enlarged section of the textile of the cover arrangement according to the invention from Fig. 1 with at least one yarn in a loose state; and Fig. 5 a schematic perspective sectional view of the yarn of the textile from Fig. 4.

[0024] As from Fig. 1 to 5, a covering arrangement 10 for an interior component 2 of a vehicle has a textile 20 which is formed from at least one yarn 30 with a plurality of fibers 32.

[0025] According to the invention, at least one property of the textile 20 can be specifically changed by means of a change in temperature T and / or a change in air humidity LF.

[0026] The Fig. The textile 20 shown in Figures 1 to 5 is knitted from the at least one yarn 30. In an alternative embodiment of the textile 20 not shown, the textile 20 can also be woven or crocheted from the at least one yarn 30.

[0027] The Fig. The cover arrangement 10 according to the invention shown in Figure 1 can have, in addition to the textile 20 shown, a fastening arrangement (not shown) in order to detachably or permanently connect the textile 20 to the corresponding interior component 2.

[0028] As from Fig. 1, the textile 20 of the covering arrangement 10 according to the invention is arranged between the interior component 2 and an occupant 50. Alternatively, the textile 20 can also be arranged merely between the interior component 2 and an interior of the vehicle. The occupant 50 generates heat and moisture. In the illustrated embodiment, the interior component 2 corresponds to a vehicle seat 2A, which is covered with the textile 20. Alternatively, the interior component 2 can correspond to an armrest or a steering wheel or a door panel or a vehicle headliner. In a vehicle, several interior components 2 can have a corresponding covering arrangement 10 according to the invention. The dimensions of the textile 20 and the corresponding fastening arrangement are adapted to the interior component 2.The textile 20 of the covering arrangement 10 according to the invention of the corresponding interior component 2 can be in direct contact with the occupant 50 or can be arranged in the vehicle interior without direct contact with the occupant 50.

[0029] As from Fig. 2 to 5, the fibers 32 of the at least one yarn 30 change a mesh size 22 of the textile 20 depending on the temperature change T or the air humidity change LF or depending on a combination of temperature change T and air humidity change LF.

[0030] As from Fig. 2 and Fig. As can be further seen in Figure 3, the fibers 32 of the at least one yarn 30 contract with increasing temperature or with increasing air humidity, or with increasing temperature and with increasing air humidity, and are arranged more tightly in the at least one yarn 30, thereby increasing the mesh size 22 of the textile 20. If the yarn 30 has fibers 32 in a taut state, the corresponding textile 20 and the corresponding cover arrangement 10 according to the invention are more permeable, whereby breathability and ventilation are improved. The mesh size 22 of the textile 20 can increase in this case by heat generated from naturally occurring heat sources, such as the sun or the at least one occupant 50, or by artificial heat sources, such as a heater 4, 4A.By increasing the mesh size 22 as temperatures rise, the heat from a seat heater 4A of the vehicle seat 2A can be transported more quickly to the occupant 50 sitting on the vehicle seat 2A. At high temperatures, the body heat of the occupant 50 can be transported away from the occupant 50 more quickly due to the enlarged mesh size 22.

[0031] As from Fig. 4 and Fig. As can be further seen in Figure 5, the fibers 32 are arranged more loosely in the yarn 30 as the temperature and / or humidity decrease, thereby reducing the mesh size 22 of the textile 20. If the yarn 30 has fibers 32 in a loose state, the corresponding textile 20 and the corresponding cover arrangement 10 according to the invention are less permeable, thereby improving insulation properties. As a result, at cool temperatures, the body temperature of the occupant 50 on the vehicle seat 2A remains with the occupant 50, keeping them warm.

[0032] As from Fig. 3 and Fig. 5, the fibers 32 comprise infrared-active carbon nanotubes 34. The carbon nanotubes 34 can enclose a number of different synthetic materials that comprise the individual fibers 32. The wavelength of infrared radiation at which the carbon nanotubes 34 are transparent, or which the carbon nanotubes 34 reflect, depends on the state of the fibers 32. In the illustrated embodiment of the textile 20, when the fibers 32 are taut, wavelengths of infrared radiation are transmitted that correspond to the body temperature of the occupant 50, thereby further improving the breathability and ventilation of the covering arrangement 10 according to the invention. When the fibers 32 are loose, wavelengths of infrared radiation that correspond to the body temperature of the occupant 50 are reflected, thereby further improving the insulating capacity of the covering arrangement 10 according to the invention.

[0033] As from Fig. 1, the illustrated covering arrangement 10 according to the invention additionally has an energizing device 40. By energizing the carbon nanotubes 34, the state of the fibers 32 and the mesh size 22 of the textile 20 are influenced. For example, the fibers 32 can be converted from a loose state to a taut state by the energization. This can, for example, improve the effectiveness of seat ventilation, since the cooling air flow generated by the seat ventilation can reach the occupant 50 through large mesh sizes 22. In addition, the mesh size 22 and the reflection or permeability for certain wavelengths of infrared radiation can be adjusted independently of the current vehicle interior temperature by the energizing device 40. This can be sensor-controlled or, at the request of the occupant 50, by appropriate operating elements.
