Abstract
Description
Field of the Invention
[0001] The present invention relates to an interior component and a method for manufacturing the interior component, the interior component having a carrier element and a textile upper layer arranged on the carrier element. Background Art
[0002] In particular, textiles, especially two-dimensional knitted fabrics and / or three-dimensional knitted fabrics, are used as surface materials or upper layers arranged or fixed on the carrier elements of interior components in motor vehicles.
[0003] However, the stretchable embodiments of the textile upper layer can currently only be achieved by subsequent processes during manufacturing or by using elastic yarns. Summary of the Invention
[0004] Therefore, the object of the present invention is to overcome the above-mentioned disadvantages and to provide an interior component having a textile upper layer and a method for manufacturing the interior component, wherein the textile upper layer can be elastically stretched at least locally.
[0005] This object is solved by the combination of features according to claim 1.
[0006] The basic idea of the present invention is that the textile upper layer of the interior component has at least one elastic stretch section, for which the elasticity of the stretch section is not achieved in the case of additional, especially elastic materials, but is provided in such a way that an elastic knitted fabric structure (Maschenbindung) is directly constructed by means of a suitable knitting technique during the manufacturing process of the textile upper layer. Here, in particular, a two-dimensional knitted fabric or a three-dimensional knitted fabric is manufactured by means of a knitting machine, especially a flat knitting machine. In addition, in particular, non-elastic yarns are used instead of elastic yarns.
[0007] The characteristic knitted fabric structure relates to the way of manufacturing textiles, especially knitted products. In the knitted fabric structure, loops made of yarns are knitted together with each other, thereby producing a fabric.
[0008] The elasticity of knitted fabric structure textiles (Maschenbindungstextilien) depends on different factors, including the yarns used, the knitting pattern, and the knitting technique. However, it is important to note that not all knitted fabric structure fabrics (Maschenbindungsgewebe) have the same elasticity. Here, the present invention utilizes the characteristics of the textile upper layer, according to which the elasticity varies according to the knitting pattern and the type of yarn. Some knitted fabric structures are highly stretchable, while other knitted fabric structures are less stretchable.
[0009] Within the scope of the present invention, a distinction is made between elastic knitted fabric structures and inelastic knitted fabric structures.
[0010] Here, an inelastic knitted fabric structure or an inelastic knitting pattern is a knitted fabric structure in which the resulting knitted piece is generally less stretchable and cannot stretch as easily as in the case of an elastic knitting pattern.
[0011] An elastic knitted fabric structure is a knitting technique in which the final product has high elasticity, which means that the final product can stretch easily and then return to its original shape. There are different knitting patterns and knitting techniques that can produce an elastic knitted fabric structure. Within the scope of the present invention, in an elastic knitted fabric structure, it is possible to stretch, in particular, by at least 20% of the extension dimension in the non-stretched state.
[0012] Advantages of the elastic stretch section of the textile upper layer are, for example, that the elastic stretch section has high stretchability and reversibly returns to its original shape when the stretch is released. In addition, the elastic stretch section has good adaptability to the carrier element of the inner member. Furthermore, the textile upper layer is arranged and / or fixed on the carrier element such that at least the elastic stretch section of the textile upper layer can also stretch elastically in the assembled state.
[0013] Therefore, according to the present invention, an inner member is proposed, in particular an inner member of a motor vehicle, which inner member has a carrier element and a textile upper layer arranged on the carrier element. Here, the textile upper layer is a knitted fabric and has at least one elastic stretch section. The at least one elastic stretch section of the textile upper layer has an elastic knitted fabric structure. Furthermore, the textile upper layer is arranged and / or fixed on the carrier element such that at least the elastic stretch section of the textile upper layer can stretch elastically.
[0014] In an advantageous embodiment variant of the present invention, it is provided that the textile upper layer has at least one further elastic stretch section and / or a plurality of further elastic stretch sections.
[0015] In one embodiment of the present invention, it is provided that the elastic stretch sections extend parallel to each other along the textile upper layer and / or are constructed and / or arranged in a predefined pattern, in particular in a honeycomb structure, polygon, trapezoid.
[0016] Preferably, the inner member is constructed such that at least one elastic stretch section of the textile upper layer has at least one pleated area including at least one pleat.
[0017] In a further advantageous variant according to the invention, fixing means are provided for fixing the textile upper layer in the extended state.
[0018] Furthermore, the following embodiment is advantageous, in which the textile upper layer has integrated, in particular woven-in, finishing elements.
[0019] In a preferred embodiment of the invention, openings are formed in the textile upper layer. The openings are in particular arranged, further in particular slotted, segmented and / or formed in the at least one elastic stretch section during knitting of the textile upper layer. Further advantageously, receiving means, preferably bags, compartments, bins and / or consoles, are arranged in particular at the openings.
[0020] In a further advantageous variant, it is provided that the entire textile upper layer consists of one or more elastic stretch sections.
[0021] The internal component according to the invention is constructed in a preferred embodiment such that the elastic knitted fabric structure of the elastic stretch section is a hem pattern (Bündchenmuster), a cable pattern (Zopfmuster), a diamond pattern, a ripple pattern, a jersey pattern (Jerseymuster) and / or a plain knitted fabric pattern (glattes Maschenmuster). These embodiments of the knitted fabric structure are particularly suitable for achieving an elastic knitted fabric structure.
[0022] The hem pattern or rib pattern (Rippenmuster) is very elastic or provides the most elastic knitted fabric structure, in which front and back loops (rechte und linke Maschen) (rib structure (Rechts-Rechts-Maschen) and purl stitch structure (Links-Links-Maschen)) are knitted alternately. Although the cable pattern is generally less elastic than the hem pattern, it provides a certain degree of stretch. The elasticity then depends on the number and size of the cables. A very elastic fabric can be produced using a diamond pattern (double knitting) since it includes two material layers. Thus, double knitting can be used for stretchable and reversible materials. The ripple pattern produces an elastic fabric with a wavy design. This pattern is less elastic than the hem pattern but still provides a certain degree of stretch. Elastic stretch sections produced using a jersey pattern or a plain knitted fabric pattern can also have sufficient elastic stretchability to implement the invention, although the elasticity of the loops (Maschen) knitted in plain right knitting is less than that of the hem pattern. The same applies to rib knitted fabric structures.
[0023] The elasticity of a knitted piece depends not only on the selected knitting technique, but also on factors such as the yarn used, the needle size, and the knitting tension. In order to achieve the desired elasticity in their knitting projects, it can be useful to experiment with different knitting techniques and settings.
[0024] In one embodiment of the invention, it is provided that the textile upper layer consists of inelastic yarn. Within the scope of the present invention, a distinction is made between elastic and inelastic yarns. Elastic yarns often contain synthetic fibers that give the yarn elasticity, such as elastane (spandex) or rubber. These yarns can stretch and then return to their original shape. Inelastic yarns, especially those made of natural fibers such as cotton, linen, or silk, generally do not exhibit significant elasticity. Although these inelastic yarns can stretch to a limited extent, they generally do not or do not fully return to their original shape.
[0025] For a preferred embodiment variant, the internal component according to the invention is configured as and / or can be used as an alternative element for automotive seats, steering column trim, card pockets, door pockets, glove boxes, headliners, covers, interior trim, center consoles, and / or luggage compartment nets.
[0026] Furthermore, according to the invention, there is provided a method for manufacturing an internal component, in particular for a motor vehicle, according to the above disclosure, the internal component having a carrier element and a textile upper layer arranged on the carrier element. Here, the textile upper layer is manufactured by means of a knitting machine, in particular a flat knitting machine. Furthermore, at least one elastic stretch section is configured during the manufacture of the textile upper layer. Furthermore, the textile upper layer is arranged and / or fixed on the carrier element such that at least the elastic stretch section of the textile upper layer can stretch elastically.
[0027] The features disclosed above can be combined arbitrarily, provided that this is technically feasible and the features do not contradict each other. Description of the Drawings
