Description

[0001] The invention relates to a piping for a cover element of a motor vehicle.

[0002] Piping is known from the state of the art in a wide variety of forms. In the manufacture of upholstery covers, for example, for vehicle seats, piping is used to conceal seams or as decoration. Physically, piping also reinforces the edges of vehicle seat upholstery covers. This makes the vehicle seats more resistant to abrasion.

[0003] The piping known from the state of the art usually consists of a cord wrapped in fabric, leather, or other material. This cord is then inserted into the upholstery cover to create a thin bead.

[0004] In order to improve the visual appeal of an upholstery cover, piping is known from the prior art in which the piping core is transparent and connected to a light source.

[0005] With the well-known piping, customization, for example of the piping color, is often not possible or only possible at considerable expense.

[0006] An object of an embodiment of the invention is to propose a piping for a cover means of a motor vehicle, which can be easily customized by a user.

[0007] This object is achieved by a piping for a cover means of a motor vehicle, with at least one piping core, with at least one transparent and / or translucent piping casing in which the piping core can be arranged or is arranged, which surrounds the piping core completely or at least in sections with respect to a circumferential direction running transversely to the longitudinal axis of the piping core and which is designed to be elastically deformable, in particular elastically stretchable, at least in the circumferential direction, and with at least one planar piping flag which is fixed to the piping casing and to which at least one cover means can be fixed or is fixed.

[0008] Because the piping includes a piping sheath that is transparent and / or translucent, a piping core comprising a color can shine through the piping sheath to the outside or be visually perceptible from the outside.

[0009] Because the piping sleeve is elastically deformable, at least in the circumferential direction relative to the longitudinal axis of the piping core, the piping core can be easily moved and, in particular, replaced within the piping sleeve. This allows users to easily and cost-effectively replace the piping core, particularly without having to visit a workshop, and thus customize the piping.

[0010] It proves to be advantageous if the elastic deformability of the keder jacket, at least in the circumferential direction, comprises a maximum of 15%, in particular a maximum of 10%, of the undeformed state.

[0011] This allows for the arrangement of piping cores of different diameters within the piping casing. This also allows the user to customize the extension of the bead formed by the piping.

[0012] Furthermore, embodiments of the piping are provided in which the piping core is detachably fixed, in particular by frictional engagement, in the piping casing and is movable relative to the piping casing along the longitudinal axis of the piping core when a certain tensile force is exceeded and / or in which the piping core comprises a diameter transverse to the longitudinal axis in which the piping core is designed to correspond, in particular complement, to the hollow space formed by the piping casing and the piping casing is undeformed, or in which the piping casing is deformed by a maximum of 5% compared to the undeformed state.

[0013] Because the piping core is releasably secured, particularly by frictional engagement, in the piping casing, the piping core can be fixed relative to the casing during normal operation. The frictional engagement can be increased if the piping core has a diameter larger than the diameter of the cavity in its undeformed state. In this case, the casing is stretched relative to its undeformed state, exerting an additional tensile force on the piping core.

[0014] In principle, it is conceivable that the piping core, when arranged in the piping casing, is arranged entirely within the piping casing. The replaceability and accessibility of the piping core can be simplified if the piping core protrudes from the piping casing with a free first end section accessible from the outside at a coupling point of the piping casing, at which the piping core can be inserted into the piping casing, in an arrangement arranged in the piping casing, and / or if the piping core protrudes from the piping casing with a free second end section accessible from the outside at a coupling point of the piping casing, at which the piping core can be removed from the piping casing, in an arrangement arranged in the piping casing.

[0015] In this case, the piping core protrudes beyond the piping casing on both sides. This makes the piping core easier to grasp and more accessible for manual replacement.

[0016] In order to prevent the welt core from being accidentally pulled into the welt casing, embodiments of the welt comprise at least one cap element which is fixed detachably, in particular by means of frictional or positive locking, or non-detachably, in particular by means of material, frictional or positive locking, to the free first end section or to the free second end section of the welt core.

[0017] In a further development of the latter embodiment, it proves to be advantageous if the cap element has a diameter transverse to the longitudinal axis of the welt core which is larger than the diameter of the welt core and which is smaller than the diameter of the welt jacket stretched to its maximum extent in the circumferential direction.

[0018] If the cap element has a diameter transverse to the longitudinal axis of the piping core that is larger than the diameter of the piping core, it is easy to ensure that the piping core cannot be accidentally drawn into the piping casing. Because the cap element has a diameter that is smaller than the diameter of the circumferential direction of the piping casing when fully stretched, it can be ensured that the piping core with the cap elements can be pulled through the piping casing, for example, to be replaced.

[0019] At least one of the at least one cap element can be fixed to the piping core by means of gluing, welding or shrinking.

[0020] In order to facilitate the exchangeability of a piping core, it proves to be advantageous if the piping has at least two cap elements, wherein a first cap element is fixed to the first free end section of the piping core and wherein a second cap element is fixed to the second free end section of the piping core and / or if the piping has at least one coupling unit which has at least one receptacle on or in the first cap element or in the second cap element and which comprises at least one coupling element on the second cap element or on the first cap element, which is designed to correspond, in particular complementarily, to the receptacle and which can be detachably fixed in or on the receptacle.

[0021] This makes it possible to replace a piping core located in a piping casing with another piping core by attaching a cap element encompassing the coupling element or the receptacle to the cap element encompassing the receptacle or the coupling element. This simply requires pulling on the free cap element of the piping core, which then pulls the new piping core into the piping casing.

[0022] The term “respectively” is used here in accordance with its etymological origin in the sense of “and in the other case”.

[0023] The piping core can, in principle, be designed in any way. Conceivable embodiments include transparent and / or translucent piping, a coloring such as a coating or dyeing, and / or an actively emitting illuminant, such as a light source, in particular an LED or an electroluminescent light cord, or a passively emitting illuminant, such as a light guide, neon light cord, fluorescent body, or phosphorescent body.

[0024] This allows for different color schemes or lighting options that can be seen from the outside through the transparent and / or translucent piping.

[0025] It proves to be advantageous if the first cap element and / or the second cap element comprises a light coupling section through which the first cap element and / or the second cap element can be coupled to a light coupling point of a light source and / or the welt core designed as a light guide extends within the first cap element and / or the second cap element up to the light coupling section.

[0026] In such a case, the first cap element and / or the second cap element can also be used to fix the piping core to a light source.

[0027] Finally, it proves to be advantageous if the piping jacket and the at least one piping flag form a common one-piece component and / or that the piping jacket and / or the piping flag comprise a flexibly bendable textile or a flexibly bendable plastic, in particular polyvinyl chloride, polyethylene or polypropylene.

[0028] In principle, it is conceivable for the piping sheath and at least one piping flag to both be transparent and / or translucent. Furthermore, the piping flag can also be opaque or impermeable to light. If the piping sheath and piping flag comprise a single, integral component, they can, for example, comprise a plastic injection-molded part. If the piping flag is not transparent and / or translucent, the plastic injection-molded part can then comprise a two-component plastic injection-molded part.

[0029] In addition, designs of the piping are conceivable in which at least two piping flags are provided on the piping casing.

[0030] Further features, details and advantages of the invention emerge from the appended patent claims, from the drawings and the following description of preferred embodiments of the piping.
