Description

[0001] The invention relates to a cover for a seat, in particular a backrest cover or side cover for a vehicle seat. Furthermore, the invention relates to a method for manufacturing such a cover.

[0002] DE 30 22 017 C2 discloses a fiber composite material for a support component. DE 198 15 115 A1 discloses a leather-covered interior trim component for a vehicle.

[0003] From DE 94 01 121 U1 a textile surface structure for seat covers or upholstery for seats in motor vehicles is known.

[0004] Generally, covers for a vehicle seat are known as coverings for the side and / or backrest areas of the vehicle seat.

[0005] The object of the present invention is to provide an improved cover compared to the prior art, in particular a lightweight and strong cover, as well as an improved method for manufacturing such a cover.

[0006] The object of the invention is achieved by a cover for a seat, in particular a backrest cover and / or side cover for a vehicle seat, wherein the cover is formed from a cover material blank or layer and a carrier material blank or layer and an adhesive fleece arranged between them. The adhesive fleece can be formed as a separate layer and inserted or pre-assembled on the carrier material. In other words, the cover or panel according to the invention is manufactured as a separate component, in particular a composite component or 3D molded part, the cover material blank or layer of which is bonded to the carrier material blank or layer by means of the adhesive fleece or layer arranged between them, in particular a porous and / or breathable one.

[0007] The advantages achieved with the invention lie particularly in the fact that the weight of such a cover or panel is exceptionally light. Furthermore, one and the same press can be used for different cover materials, such as leather, vinyl, or fabric. This makes the production of the cover in various shapes simpler and more cost-effective. Such a cover is particularly suitable as a backrest or side cover / panel for a vehicle seat.

[0008] In one possible embodiment, the cover material and the substrate are joined together by means of an adhesive fleece or layer using a pressure forming and joining process, in particular a welding process. For example, the cover material and the substrate can be joined together by means of an adhesive fleece or adhesive layer using a pressure forming and joining process with high-frequency energy in the form of an electromagnetic field (also called high-frequency welding). Such a pressure forming and joining process activates the adhesive fleece / layer located between the cover material layer / cut and the substrate material layer / cut. In particular, the pressure, welding power, welding duration, and cooling duration influence the bond between the cover material cut / layer and the substrate material cut / layer.

[0009] The adhesive fleece has a porous structure and therefore open spaces. The adhesive fleece can be arranged as a separate layer between the backing material layer and the cover material layer. Alternatively, the adhesive material can be pre-applied to the backing material. In this case, the adhesive material is applied to the surface of the backing material facing the cover material.

[0010] In one possible embodiment, the cover material is a vinyl material, in particular a laminated or non-laminated vinyl material, for example, polyvinyl chloride (PVC). Alternatively, the cover material can be a laminated or non-laminated textile material, in particular a woven fabric, or a laminated or non-laminated natural material, in particular leather. The cover material may be pre-treated and is, for example, available as a continuous material that is cut to size for the production of the cover or seat trim. A resulting cover material blank has a shape adapted to the final form of the cover. This shape of the cover material is also called the cover material blank. The cover material may be reinforced and / or coated. The cover material may also be smooth or porous.In relation to the substrate material, the cover material is thin, whereas the substrate material has a greater thickness.

[0011] In another embodiment, the backing material is a carrier nonwoven, in particular a pressed felt, a carpet, or a knitted fabric, for example, made of synthetic fibers and / or natural fibers and / or reinforcing fibers. The fiber material can be pre-shaped and optionally pre-treated. The fiber material is, for example, a continuous material that is cut to size for the production of the cover. A resulting backing material blank has a shape adapted to the final shape of the cover. This shape of the backing material is also called the backing material blank. The fiber material can be made of one or more different materials, for example, polyester, polyethylene, polypropylene, and / or polyurethane. It can be made of tangled fibers, in particular recycled or non-recycled natural and / or synthetic fibers.The carrier nonwoven can be made of a three-dimensionally stochastically oriented fiber material. Alternatively, it can be a woven or nonwoven fabric. It can optionally be thermally pretreated. Advantageously, this is a three-dimensionally stochastically oriented fiber material. For example, the plastic fibers are made of a thermoplastic, in particular a modified and weldable thermoplastic. For example, the plastic fibers are made of polyethylene terephthalate (PET), polyester, or a synthetic polymer, in particular polylactic acid (PLA). A mixture of fibers from different plastics is also possible.

[0012] According to the disclosure, the adhesive fleece is, in particular, a water- and / or solvent-free adhesive fleece, for example, a co-polyester fleece or a thermoplastic fleece. The adhesive fleece has, in particular, an open structure. That is, it contains hollow spaces. Upon activation, in particular by heat and pressure for a certain period of time, an open adhesive bond forms.

[0013] The covering surprisingly has a thickness in the range of 3 mm to 5 mm, particularly from 4.0 mm to 4.5 mm. Furthermore, it has surprisingly been found that such a thin covering has a hardness greater than 60 Shore A, specifically 65 Shore A for a 1000 g carrier nonwoven or 62 Shore A for an 800 g carrier nonwoven.

[0014] Preferably, the cover is characterized by a three-dimensional shape, in particular by a shell shape.

[0015] A device for manufacturing the cover comprises a forming and joining unit. The forming unit is, in particular, a press, such as a forming press, comprising an upper forming part and a lower forming part. The joining unit is, in particular, a generator. For example, the joining unit comprises a high-frequency generator that generates an electromagnetic field.

[0016] Furthermore, the generator is coupled to the press for the combined pressure forming and pressure joining process of the cover material blank and the carrier material blank for the production of the cover.

[0017] The press can be designed in particular as an electric, hydraulic or pneumatic press.

[0018] The generator produces an electromagnetic field between two electrodes, for example at a high frequency in a range greater than 20 MHz, particularly 25 MHz or 27 MHz. This generates heat, also known as welding heat, through molecular vibrations (frictional heat) directly in the materials to be joined, especially welded, particularly in plastic materials or in natural and plastic materials, and especially in the area of ​​their joint.

[0019] The negative molded part and the positive molded part have a negative or positive matrix shape corresponding to a final shape of the cover.

[0020] The inventive method for manufacturing the cover comprises the following steps: - Opening a forming and joining unit comprising at least one positive molded part and one negative molded part, - Positioning a carrier material blank and a cover material blank with an adhesive fleece or adhesive layer arranged between them in the open forming and joining unit on one of the molded parts, - Closing the forming and joining unit by moving the negative mold part towards the positive mold part or vice versa, - Joining the cover material cut to the carrier material cut using the adhesive layer or adhesive fleece by welding and forming the cover by pressure forming, and - Opening the forming and joining unit and removing the formed cover.

[0021] In a further training course, the cover material layer / cutout is joined to the carrier material layer / cutout using the adhesive layer / nonwoven cutout by high-frequency welding. For this purpose, for example, an electromagnetic field is generated in the area of ​​the joining or seam point of the materials to be joined, whereby these material layers are joined together by pressing the negative molded part onto the positive molded part or vice versa using the activated adhesive layer or the adhesive nonwoven and formed into the final shape of the cover, in particular pressure forming.

[0022] Exemplary embodiments of the invention are explained in more detail with reference to the drawings. These show: Fig. 1A schematically in enlarged vertical section an area of ​​a cover formed from a cover material layer and a carrier material layer and an adhesive fleece or adhesive layer arranged between them; Fig. 1B to 1D schematically in perspective representations various examples of a manufactured cover, Fig. 2.

Schematic top view of an example of a carrier material cut, Fig. Figures 5A to 5E schematically illustrate a process for manufacturing a cover according to the invention. Fig. 6 schematically in perspective view an embodiment of a forming and joining unit in the open state, and Fig. Figures 7A to 7H schematically illustrate a process flow for applying an optional pocket to the cover according to the invention.

[0023] Corresponding parts are marked with the same reference symbols in all figures.

[0024] Fig. Figure 1A schematically shows an enlarged vertical section of an area of ​​a cover 1. The cover 1 is, for example, a backrest cover, a side cover, a backrest shell or seat shell for a vehicle seat.

[0025] The cover 1 is formed from a cover material layer 2, an adhesive fleece 3 or adhesive layer and a carrier material layer 4.

[0026] The adhesive fleece 3 can be formed as a separate layer. Alternatively, an adhesive material or substance can be applied to or pre-assembled as an adhesive layer on the carrier material layer 4. The invention is described below with reference to a separate adhesive fleece 3. The invention is applicable analogously to a carrier material layer 4 pre-assembled with an adhesive layer.

[0027] The adhesive fleece 3 is arranged between the cover material layer 2 and the carrier material layer 4. The cover material layer 2 and the carrier material layer 4 are joined together by means of the adhesive fleece 3, in particular by means of a material bond. The cladding 1 according to the invention is thus manufactured as a composite component.

[0028] The top layer 2 can be thin, whereas the base layer 4 can be thicker. In other words, the top layer 2 has a smaller thickness than the base layer 4.

[0029] Surprisingly, cover 1 has a thickness D in a range of 3 mm to 5 mm, in particular from 4.0 mm to 4.5 mm, and is therefore significantly thinner than conventional covers with thicknesses greater than 5 mm or 8 mm.

[0030] Furthermore, the cover 1 can have a hardness greater than 60 Shore A, in particular 65 Shore A for a 1000 g carrier material blank 4.1 (in particular a 1000 g carrier fleece) or 62 Shore A for an 800 g carrier material blank 4.1 (in particular an 800 g carrier fleece).

[0031] Fig. Figures 1B to 1D schematically show various examples of a manufactured cover in perspective drawings.

[0032] Fig. Figure 1B shows the reverse side of a cover 1, which is shaped as a shell-shaped backrest cover or a backrest cushion element. The reverse side of the cover 1 has a recess 1.1. The recess 1.1 is molded into the cover 1 during its manufacture. The recess 1.1 serves, for example, to provide legroom.

[0033] Along a circumferential edge 1.3, the cover 1 has a fastening means 5 in the form of a zipper for attaching a cover.

[0034] Fig. Figure 1C shows a further embodiment of a back side of the cover 1, which is shaped as a backrest cover or a shell-shaped backrest cushion element. The back side of the cover 1 additionally has a pocket 1.2 in the recess 1.1. The pocket 1.2 can be easily and releasably fixed in the recess 1.1. The pocket 1.2 is optional.

[0035] Fig. Figure 1D shows the circumferential edge 1.3 of the cover 1 in an enlarged view.

[0036] Fig. Figure 2 shows a schematic top view of an example of a cover material cut 2.1 of the cover material layer 2 for the cover 1.

[0037] The cover material of the cover material layer 2 is, for example, a vinyl material, in particular a non-laminated vinyl material. For example, the cover material can be polyvinyl chloride. Alternatively, the cover material can be a textile material, in particular a woven fabric, or a natural material, in particular leather. The cover material may be pre-treated. The cover material is, in particular, available as a continuous material. To manufacture the cover 1, the cover material is cut to size as a cover material blank 2.1 corresponding to the final shape of the cover 1. The cover material can be reinforced and / or coated. The cover material can also be smooth or porous.

[0038] The cover material cutout 2.1 may have tongues 2.2 or other suitable fastening tabs projecting along its outer contour. After the cover 1 has been manufactured, these tongues 2.2 serve, for example, to fasten a [missing information - likely a specific item or component] to a seat, such as a vehicle seat. Fig. 5E shown seat cover 7 (trim cover).

[0039] Fig. Figure 3 schematically shows a top view of an example of an adhesive fleece 3. The adhesive fleece 3 is available, in particular, as a continuous material. To manufacture the cover 1, the adhesive fleece 3 is cut to size as adhesive fleece blank 3.1, corresponding to the final shape of the cover 1.

[0040] The adhesive fleece blank 3.1 has a shape that corresponds to the face material blank 2.1 and the backing material blank 4.1. Specifically, the dimensions and / or size of the adhesive fleece blank 3.1 are largely identical to the dimensions and / or size of the face material blank 2.1 and / or the backing material blank 4.1. The adhesive fleece blank 3.1 has a smooth contour without tongues or flaps. The shape of the adhesive fleece blank 3.1 essentially corresponds to the smaller shape of the face material blank 2.1 or the backing material blank 4.1, if one of these is smaller.

[0041] The adhesive fleece 3 is, in particular, a water- and / or solvent-free adhesive fleece, for example, a co-polyester fleece or a thermoplastic fleece. The adhesive fleece 3 has, in particular, an open structure. The adhesive fleece 3 is characterized by cavities. Upon activation, in particular by heat and pressure for a specific period of time, an open adhesive bond forms between the cover material and carrier material layers 2 and 4, respectively. This allows the finished cover 1 to be designed as a breathable composite component.

[0042] Fig. Figure 4 shows a schematic top view of an example of a carrier material cut 4.1 of the carrier material layer 4.

[0043] The carrier material is present in particular as a continuous material. To manufacture the cover 1, the carrier material of the carrier material layer 4 is cut to size as carrier material blank 4.1, corresponding to the final shape of the cover 1.

[0044] The carrier material blank 4.1 may have tongues 4.2 or other suitable fastening tabs projecting along its outer contour. After the cover 1 has been manufactured, these tongues 4.2 serve, for example, to fasten the seat cover 7 (trim cover).

[0045] The backing material is, in particular, a carrier nonwoven, for example, a pressed felt, a carpet, or a knitted fabric. The carrier nonwoven is formed, for example, from synthetic fibers and / or natural fibers and / or reinforcing fibers. The fiber material can be pre-formed and, if necessary, pre-treated. The fiber material can be formed from one or more different materials, for example, polyester, polyethylene, polypropylene, and / or polyurethane. It can be formed from random fibers, in particular from recycled or non-recycled natural and / or synthetic fibers. The carrier nonwoven can be formed from a three-dimensionally, stochastically oriented fiber material. Alternatively, it can be a woven or non-woven carrier nonwoven. It can optionally be thermally pre-treated. Advantageously, this is a three-dimensional, stochastically oriented fiber material.Plastic fibers are made from thermoplastics, particularly modified and weldable thermoplastics. For example, these fibers are made from polyethylene terephthalate (PET), polyester, or a synthetic polymer, especially polylactic acid (PLA). A mixture of fibers made from different plastics is also possible.

[0046] Fig. Figures 5A to 5E schematically show a process for manufacturing a cover according to the invention 1.

[0047] A forming and joining unit 6 is provided for the production of the cover 1, which is located in the Fig. 5A to 5D is partially shown.

[0048] Fig. Figure 5A partially shows a forming unit 6.1 of the forming and joining unit 6. The forming unit 6.1 is designed, for example, as a press, in particular a forming press. The press can be designed, in particular, as an electric, hydraulic, or pneumatic press.

[0049] The forming unit 6.1 comprises at least one negative forming part 6.1.1 and one positive forming part 6.1.2. In the exemplary embodiment, the negative forming part 6.1.1 is an upper forming part, in particular a negative compression forming part. The positive forming part 6.1.2 is, for example, a lower forming part, for example, a positive compression forming part.

[0050] The positive mold part 6.1.2 has a die M1 that corresponds to the final shape of the cover 1 to be formed. The negative mold part 6.1.1 has a negative die M2 corresponding to the die M1. In other words, the negative mold part 6.1.1 and the positive mold part 6.1.2 have a negative and positive die shape M2 and M1, respectively, corresponding to a final shape, in particular a 3D shape, for example a shell shape, of the cover 1.

[0051] The forming unit 6.1 is shown in the open state. This means that the forming parts 6.1.1 and 6.1.2 are spaced apart from each other. This allows the blanks, i.e., the cover material blank 2.1, the adhesive fleece blank 3.1, and the carrier material blank 4.1, to be loaded or inserted into the forming unit 6.1.

[0052] In an alternative embodiment, not shown in detail, of an adhesive layer pre-assembled on the carrier material blank 4.1, the carrier material blank 4.1 with the pre-assembled adhesive layer is introduced into the forming unit 6.1 such that the adhesive layer points in the direction of the cover material blank 2.1 and is arranged between the cover material blank 2.1 and the carrier material blank 4.1 in the positioned state.

[0053] The molded parts 6.1.1 and 6.1.2 are made primarily of aluminum. This allows covers 1 made of different materials to be formed and manufactured in one and the same forming unit 6.1, regardless of the material used (fabric, linyl or leather).

[0054] Fig. Figure 5B shows the opened forming unit 6.1 with blanks arranged one above the other on the positive forming part 6.1.2 - cover material blank 2.1, adhesive fleece blank 3.1 and carrier material blank 4.1. In particular, the blanks are arranged in layers and, for example, in the manner of a sandwich, one above the other and aligned with each other.

[0055] Fig. Figure 5C shows the forming unit 6.1 in the closed state and with the blanks arranged between the forming parts 6.1.1 and 6.1.2 - cover material blank 2.1, adhesive fleece blank 3.1 and carrier material blank 4.1. Fig. 5D shows a joining unit 6.2 of the forming and joining unit 6.

[0056] The joining unit 6.2 is in particular a generator 6.2.0. The generator 6.2.0 is in particular a high-frequency generator that generates an electromagnetic field F in the area of ​​the cutouts to be added, such as cover material cutout 2.1, adhesive fleece cutout 3.1 and carrier material cutout 4.1, in order to join them together by means of frictional heat from moving molecules.

[0057] For this purpose, the generator 6.2.0 is coupled with the forming unit 6.1 for the pressure forming and pressure joining process of the cover material blank 2.1 and the carrier material blank 4.1 by means of the adhesive fleece blank 3.1 for the production of the cover 1.

[0058] The generator 6.2.0, for example, comprises two electrodes 6.2.1 and 6.2.2, each coupled to one of the forming parts 6.1.1 and 6.1.2 of the forming unit 6.1, respectively. The forming parts 6.1.1 and 6.1.2 themselves can form the electrodes 6.2.1 and 6.2.2, respectively. Alternatively, the electrodes 6.2.1 and 6.2.2 can be designed separately and integrated into the forming parts 6.1.1 and 6.1.2, respectively.

[0059] The generator 6.2.0, in particular a high-frequency generator, generates the electromagnetic field F between the two electrodes 6.2.1 and 6.2.2, for example at a high frequency in a range greater than 20 MHz, in particular 25 MHz or 27 MHz. Heat, also called welding heat, is generated by molecular vibrations (frictional heat) directly in the materials to be joined, in particular welded, especially in the blanks, such as cover material blank 2.1, adhesive fleece blank 3.1, and carrier material blank 4.1. This results in the activation of the adhesive or adhesive material of the adhesive fleece blank 3.1 or the adhesive layer and its melting and fusion with the cover material of the cover material layer 2 and the carrier material of the carrier material layer 4, thereby joining them together.

[0060] Heating the forming unit 6.1, in particular its forming parts 6.1.1, 6.1.2, and / or the cover material, carrier material and / or adhesive before and / or during the joining of the layers is not required. This allows the cover 1 to be produced simply and cost-effectively in various material variations using one and the same forming and joining unit 6.

[0061] Fig. Figure 5E shows the shaped cover 1 with the tongues 2.2 and 4.2 for attaching the cover 1 to the seat cover 7 after removing the cover 1 from the forming and joining unit 6.

[0062] The inventive method for manufacturing the cover 1 comprises, in summary, at least the following steps: - Opening of the forming and joining unit 6 ( Fig. 5A), - Positioning the cover material blank 2.1, the adhesive fleece blank 3.1 and the carrier material blank 4.1 into the opened forming and joining unit 6, for example on the positive molded part 6.1.2 ( Fig. 5B), - Closing the forming and joining unit 6.1, for example by moving the negative forming part 6.1.1 in the direction of the positive forming part 6.1.2 ( Fig. 5C), - Joining the cover material cutout 2.1 with the carrier material cutout 4.1 by means of the adhesive fleece 3 or the adhesive layer by welding and forming the cover 1 by pressure forming ( Fig. 5D), and - Opening the forming and joining unit 6 and removing the formed cover 1 ( Fig. 5E).

[0063] The cover material layer / cut 2.1 can be joined to the carrier material layer / cut 4.1 by means of the adhesive layer / nonwoven cut 3.1, for example by high-frequency welding. For this purpose, a field F, in particular an electromagnetic field, is generated in the area of ​​the joining or seam point of the materials to be joined, whereby these material layers are joined and formed into the final shape of the cover 1 by pressing the negative molded part 6.1.1 onto the positive molded part 6.1.2 or vice versa, using the activated adhesive layer or the adhesive nonwoven cut 3.1, in particular by pressure forming.

[0064] The manufactured and shaped cover 1 can then be sewn to the seat cover 7 or attached using a zipper. The cover 1 can be applied and fastened to the seat, in particular a cushion element or a seat support, either separately or together with the seat cover 7.

[0065] The cover 1 can be part of a seat component and, for example, cover a side surface or a backrest surface.

[0066] Fig. Figure 6 schematically shows a perspective view of an embodiment of the forming and joining unit 6 in its open state. The forming and joining unit 6 can additionally include a fixing frame 6.1.3 to position, align, and fix the blanks, such as the cover material blank 2.1, the adhesive fleece blank 3.1, and the carrier material blank 4.1, within the forming and joining unit 6.

[0067] Fig. Figures 7A to 7H schematically show a process sequence for applying an optional pocket 1.2 to the cover 1 according to the invention.

[0068] When forming and joining the exemplary cover 1 according Fig. 7A to 7H in the forming and joining unit 6, fastening openings 8 are inserted or formed into this cover 1. Optionally, a recess 1.4 can be formed into the formed recess 1.1. Alternatively, the fastening openings 8 and / or the recess 1.4 can be subsequently added to the already formed and joined cover 1 (as shown above based on the Fig. (described in sections 5A to 5E) are introduced.
