Definitions

  • the invention relates to a cushion element with a cover, which covers a core made of elastic material, preferably made of a foam, and is fastened to it by an anchoring element which is enclosed by the core, as well as a method for its manufacture.
  • Upholstery elements for example for the interior of motor vehicles, generally consist of an elastic core, the surface of which is completely or partially covered by a cover, for example made of fabric, leather or the like, for protection and for optical design.
  • a cover for example made of fabric, leather or the like, for protection and for optical design.
  • foams preferably polyurethane
  • anchoring elements which are enclosed by the core material, are common in the prior art for the large-scale distribution of force loads that occur.
  • Utility model DE shows an example of an anchoring element in the form of a profile which can be foamed into a core
  • the anchoring element described has the particular advantage that, with the exception of a network of fibers, it is made of poly there is lyurethane so that recycling of the upholstery material is made considerably easier by a uniform material and avoidance of metal parts.
  • Fastening means for example hooks, which penetrate the foam, which is often provided with cutouts for this purpose, serve to connect the anchoring elements and the cover.
  • the anchoring elements known in the prior art require a high outlay in the manufacture of the upholstery, the clinging of the cover and anchoring elements and their insertion into the foaming tool being particularly labor-intensive. Furthermore, there is a permanent connection between the core of the upholstery and the cover, which makes it considerably more difficult to replace it in the event of wear or for aesthetic reasons.
  • the task is to develop an upholstery element in which the effort for anchoring the cover is reduced and its replacement is possible without loosening permanent connections.
  • the surface of the core has a groove which widens inwards, and an edge of a material strip is attached to the cover on the inside, the opposite edge of which is provided with a dimensionally stable body, the body in the groove is inserted and the maximum diameter of the body is in the groove and larger than that minimum diameter of the groove is.
  • the core of the proposed cushioning element has in its surface a groove in the form of a hollow profile, which is on the bottom side, i.e. widened towards the inside of the core.
  • a preferably profile-shaped body is located in the groove, its maximum diameter being arranged in the groove and being larger than its minimum diameter.
  • the narrowest area of the groove is expediently its opening.
  • a dimensional stability of the body is only necessary for adequate anchoring, so that its inherent elasticity can absolutely correspond to that of the core material.
  • the connection between cover and body is made by a strip of material, which can also be part of the latter.
  • Strips of material made of flexible material, for example a net or a fabric, are expedient, which are attached to the edge on the inside of the cover, for example attached.
  • the groove is preferably filled by a single body in the form of a profile, the strip of material being connected to the body and cover along its long sides. Alternatively, it is conceivable to insert several bodies into a groove, each of which is attached to the cover by means of individual strips.
  • the cover is anchored to the core of the upholstery element in such a way that the core with the groove is first produced by a customary production process.
  • the groove is usually shaped by a corresponding increase in the shape of the molding tool, for example during injection molding.
  • the body and cover are connected by the strip of material, for example by being attached to both.
  • the type of connection can vary with different designs of body and material strips, as will be explained later.
  • the main advantage compared to the prior art is that the connection to be produced between the body and the inside of the cover is freely accessible for processing, whereas previously the attachment was carried out in a confined space between the cover and the core of the cushion Has.
  • the body is pressed into the groove, which creates a load-bearing connection between the core and the cover that can be released by sufficient tension. It is conceivable to pull apart or push the edges of the groove apart to make it easier to press in.
  • the proposed upholstery element is considerably easier to manufacture than it is in the prior art Technology is possible. There is no longer any need to pre-prepare prefabricated anchoring elements or to insert them into the foam mold. Since curved, square or intersecting grooves are also possible, any seam patterns can be produced on the upholstery surface. There is no need for complex clinging between the cover and the anchoring element. Furthermore, the cover can be detached from the core of the cushion in a simple manner, for example in order to replace it in the event of wear. However, the low cost of loosening and attaching the cover, which is easily possible even for laymen and without tools, suggests, for example, to replace the covers for a motor vehicle for aesthetic reasons or to adapt to the season.
  • the weight of the upholstery which is particularly important when used in a motor vehicle, and in the recycling of the upholstery material.
  • Metal-free cushions can in particular be easily crushed or chemically dissolved.
  • the attachment of the cover according to the invention can also be used for cores made of different materials, for example with a spring-loaded foam layer, provided that there is an outer area made of elastic and homogeneous material of sufficient depth to introduce a groove.
  • the strip of material is a nonwoven, which consists, for example, of polypropylene fibers and passes through Sewing can easily be attached to the cover.
  • a material strip is preferred, the side of which facing away from the cover consists of two partial strips running next to one another.
  • the cross section of the strip of material is thus approximately of the shape of a "T" or "Y", the base of which is attached to the cover. The end splitting into two partial strips improves and expands the possibilities for attaching a body.
  • Suitable cross sections of the groove are, for example, wedge-shaped or T-shaped, the vertical line of the iir p ii preferably being oriented perpendicular to the surface of the core.
  • the opening or narrowest point of the groove can be very narrow and, in extreme cases, represent a slot in the core surface.
  • the groove it is expedient for the groove to have rounded edges in its cross section, which facilitate demolding of the core.
  • the body preferably has similar material properties to the core, so that it cannot be felt in an uncomfortable manner by the user of the cushion. In addition, mutual damage avoidance of groove and body.
  • the body thus preferably consists of a foam which is glued to the material strip, for example.
  • an intensive, resilient connection can also be produced by foam encasing on the edge. A particularly intensive connection can be achieved if the material strip is subdivided into partial strips on the edge.
  • Forming in a foaming tool generally gives foam parts a closed-pore, smooth surface structure, so that two molded parts slide on one another with comparatively little friction. To ensure the liability of the body in the

  • the edges of the open foam pores act similarly to hooks and are slightly pressed into the smooth surface of the groove, since the load is limited to narrow webs between the pores.
  • the advantageous consequence is a substantial increase in the static friction between the body and the groove and thus a firm fit.
  • the manufacture in the extruder permits an advantageous and inexpensive endless production of the body.
  • An alternative body is an integral part of the material strip and can be created, for example, by stabilizing the shape of the material of a fleece. make it.
  • a thermal treatment of the nonwoven material which causes the fibers to harden or melt on the surface, is particularly suitable for this purpose.
  • the fleece is compacted with intensively connecting fibers lying one on top of the other, so that a dimensionally stable body is formed which can be fixed in the groove.
  • Complete stabilization of the shape of the material strip ie also in the area between the body and the cover, is conceivable, but is generally not necessary.
  • An advantage is a body that widens in the direction of the opening of the groove, ie in the direction in which the groove becomes narrower. At its widest point, the body is bordered on the outside by an edge.
  • a profile with a trapezoidal cross section is suitable, for example, the narrower of the parallel trapezoidal sides being oriented toward the bottom of the groove.
  • the edge of the body presses into the wall of the groove and thus fixes it in its position.
  • the cover fastening can be considerably improved in this way.
  • the only prerequisite for hooking into the groove wall is that the body widens relative to the cross section of the groove.
  • a body with a rectangular or T-shaped cross section For a heavy-duty connection, the body has the cross section of a barb, ie tips or edges which point at an acute angle against the opening of the groove.
