Description

Component and method for its production

description

The invention relates to a method for producing a component, in particular a carrier component for a seat, and a vehicle seat. Furthermore, the invention relates to a component produced by the method.

The prior art according to the Applicant's EP 2 933 136 A1 discloses a cushioning element and a method for producing a

Upholstery element known. The upholstery element is made of a

Fiber composite formed with a three-dimensional stochastically oriented fiber material. The fiber composite material comprises at least one weldable thermoplastic.

Also from DE 30 22 017 C2 is a fiber composite material for a

Carrier component known.

Object of the present invention is to provide a comparison with the prior art improved method for producing a component and an improved component produced by the method.

The object is achieved by a method for

Production of a component and by such a component.

In a method for producing a component, according to the invention a fiber layer, in particular a nonwoven fabric made of a three-dimensionally stochastically oriented fiber material, is thermally pretreated such that a porosity of the fiber layer can be adjusted. This shows that manufactured component has a thickness of less than 8 mm, in particular equal to or less than 7 mm and / or a density of greater than 90 kg / m ³ .

In particular, the fiber layer, in particular a prefabricated or preformed nonwoven fabric, has a density of greater than 90 kg / m ³ .

A further development provides that the manufactured component has a density of greater than 100 kg / m ³ , in particular in a range of 100 kg / m ³ to 300 kg / m ³ .

In particular, the density is the mass density with a quotient of the mass m of the component and its volume. In one possible measurement, a measurement sample is cut from the component and determined by means of a conventional measuring method, for example by measuring the displaced liquid volumes. Alternatively, the density can also be determined theoretically by specifying the volume of the component and the mass, for example the amount of fiber and foam material added.

In particular, by such an adjustable density and therefrom

resulting adjustable porosity of the fiber layer, in particular of the nonwoven fabric, is the penetration of a subsequently applied

Foam material controllable. As a result, a component is also produced with an adjustable density of greater than 90 kg / m ³ and thus with a predetermined strength and hardness.

The fiber material is preformed and optionally pretreated. The fiber material can be made of one or more different materials, for example of polyester, polyethylene, polypropylene and / or

Polyurethane be formed. It may be formed from tangled fibers, in particular from recycled or non-recycled natural and / or synthetic fibers. Alternatively, it may be a woven or nonwoven web. Due to the thermal treatment of the fiber material, this is also called thermal nonwoven. This is advantageously a three-dimensional stochastically oriented fiber material. Plastic fibers are formed for example from a thermoplastic, in particular from a modified and weldable thermoplastic. For example, the plastic fibers are made of polyethylene terephthalate (PET), of polyester or of a synthetic polymer, in particular of polylactide (PLA). Also a mixture of fibers from different ones

Plastics is possible.

For binding the fiber material, a binder, in particular a thermosetting binder, is provided. The binder is, for example, a thermosetting adhesive, in particular a halogenated hydrocarbon, for example chloroprene rubber and / or a polyurethane-based thermosetting binder, for example a PU or PUR adhesive.

In a further embodiment, the preformed fiber material, for example a nonwoven fabric, in particular a nonwoven fabric, is coated. For example, the preformed fiber material is additionally provided with a plastic layer. As a material for a plastic layer is particularly suitable polyethylene (PE). The coating material is particularly thin and is for example in the form of a

Plastic film applied to the preformed fiber material. This allows for improved air regulation. In addition, a coated preformed fibrous material, for example a coated fibrous web, is optimized and less susceptible to mechanical stresses, particularly damage, bruises, fractures.

The fiber material may, for example, on a surface side of a

Forming tool are applied. For the thermal treatment of the fiber material, this can in one embodiment in the mold even thermally treated once or several times. Alternatively, the fiber material can be prefabricated and thermally treated and placed in the mold. By the thermal treatment, the fiber material softens, wherein the thermal treatment is controlled so that a predetermined porosity can be achieved. In this case, the fiber material may optionally be preformed into a semifinished product having a predetermined porosity, in particular surface porosity.

Subsequently, a foam material, in particular polyurethane, is introduced into the mold. In this case, the mold can already be closed. Alternatively, the foam material, for example liquid polyurethane, can be introduced into the mold when the mold is open, and then the mold is closed.

For example, the preformed nonwoven fabric on the lid of a

Forming tool arranged and introduced the foam material in the bottom of the mold. Subsequently, the lid is closed, so that the liquid foam material penetrates into the nonwoven fabric.

For example, liquid components for the liquid

Foam material mixed at room temperature and placed in the mold. In particular, the liquid components are at a temperature of 18 ° C to 25 ° C, in particular from 20 ° C to 22 ° C.

processed. Due to the liquid state of the foam material, this penetrates safely and controlled into the fiber fleece or the fiber layer. In particular, there is a controlled penetration and / or penetration of the fiber fleece or the fiber layer with liquid foam material at a temperature of more than 20 °, in particular in one

Temperature range from 20 ° to 90 °. Depending on the thickness of the fiber fleece / the fiber layer, complete penetration of the fiber fleece or fiber layer with the liquid foam material may also occur. Subsequent heat supply in the mold, the liquid foam material is activated, resulting in foaming of the liquid

Foam material leads directly into the fiber fleece. For example, the liquid foam material may be provided with a blowing agent such that

Temperature-dependent is activated.

Furthermore, it is provided that, in particular, such an amount of liquid foam material is introduced into the mold or that, in addition to the partial or complete penetration of the fiber layer with the liquid foam material, a foam layer forms on at least one upper side of the fiber layer. For example, the nonwoven fabric, in particular a preformed nonwoven fabric has a basis weight in a range of 150 to 700 g / m ² .

By activation of the liquid foam material in the penetrated into the nonwoven fabric and optionally outside lying state within the mold, the component is simultaneously brought into its final shape, in particular pressed. The fiber fleece inside with the

Invaded and foamed foam material compacted and molded to a desired thickness of less than 8 mm. Thus, in the final form, the component has an outer foam layer, in particular formed on an upper side, and a partially or completely foamed nonwoven fabric. In one possible embodiment, the nonwoven fabric is already preformed, so that the nonwoven fabric is still solidified by the foam material and provided on the outside with a cushion layer.

Depending on the contour, in particular inner contour of the molding tool, the component can be partially densified differently. When using a coated preformed fibrous web less liquid Schaummate al enters the nonwoven fabric, since the coating acts as a barrier.

As a component, in particular a component for a vehicle is produced by means of the method, expediently a vehicle interior component, in particular a component for a vehicle seat, for example a

Backrest support or a seat cushion support for a vehicle seat.

The invention further relates to a particular by means of

Method produced inventive component, the one

Fiber layer, in particular a nonwoven fabric, from a three-dimensionally stochastically oriented fiber material with partially or completely penetrated foam material and in the finished state a density, in particular a total density in a range of greater than 90 g / l (= kg / m ³ ), in particular greater than 100 g / l or in a range of 100 g / l to 300 g / l, and / or has a thickness of less than 8 mm.

In this case, the fiber layer has a higher density than the foam layer. For example, the density of the fiber layer is in a range between 150 g / l and 700 g / l and that of the foam layer in a range between 100 g / l and 300 g / l. This allows a particularly thin component with a comfortable support surface, wherein the component has a total thickness of less than 12 mm, in particular a total thickness in a range of 5 mm to 12 mm, for example between 8 mm and 10 mm or less than 8 mm.

In particular, a prefabricated as a preformed nonwoven fabric

formed fiber layer has a very high rigidity. Advantageously, the fibrous layer forms a front side of the component, for example a back support or a seat cushion support, and the foam layer a back or vice versa. The fibrous layer preferably forms the rear side of the component. On the front of the component can then be formed to form the vehicle seat nor the seat of a seat cushion or a seat back, for example, by still a cushioning material and a seat cover are arranged or only a seat cover is arranged.

The fiber layer, in particular the nonwoven fabric, advantageously has a constant basis weight, so that the components produced can also be formed with a substantially constant weight per unit area. The nonwoven fabric can optionally be prefabricated to a semi-finished and preformed. In addition, the preformed nonwoven fabric may be provided with a coating, in particular a plastic coating, for example a polyethylene layer or a polyethylene film.

For preforming the fiber web and / or for thermal treatment, in particular thermal aftertreatment of a preformed

Nonwoven fabric, a heated plate may be provided, on which the nonwoven fabric or the preformed nonwoven fabric is placed to heat it and then insert it into the mold. Alternatively or in addition to the heated plate, other heating means for heating the nonwoven fabric are possible, for example, a heating by means of infrared irradiation by one or more

Infrared heaters. Ie. it is a heating of the nonwoven fabric by means of at least one heating device required to soften it in the heated state so that a predetermined porosity is adjustable at least in the surface region of the nonwoven fabric. Appropriately, liquid plastic material, in particular a liquid, foamable plastic, applied to the arranged in the mold fiber fleece and the component is formed, pressed or injection molded by means of the molding tool. As a result, only a single manufacturing station is required, in which the entire process can be carried out.

In particular, the nonwoven fabric replaces a conventional wool wadding used in the prior art, which has the described advantages of

Vorformvlieses, in particular the stiffness, does not have. Therefore, for example, an application of the fiber material to the wool mat outside of the mold and subsequent transport to the mold would not be possible or only with considerable additional effort. The thermally treated nonwoven fabric having the above-described adjustable porosity and density is formed of, for example, polyester fibers and / or other plastic fibers, especially melt fibers. Also an education from with such plastic fibers, especially melt fibers, mixed

Wool / cotton wool is possible. Ie. the fiber layer or the fiber fleece is designed such that it im in a given

The softening temperature heated state is reshapeable or malleable and stiffened by subsequent cooling again so that at least in

Surface area of the fiber layer or the nonwoven fabric a

predetermined porosity and / or a predetermined density is adjustable.

The formed from non-woven fabric with penetrated foam material component has a high rigidity and at the same time an improved

Contouring and high strength and resistance after molding or injection molding on. The nonwoven used, in particular rolled or sheet goods, for example, comprises a polyester material and / or others

Fused fibers, d. H. it expediently comprises fibers

Plastic, in particular of thermoplastic. Furthermore, it may also include, for example, natural fibers or other fibers. Suitable for forming the nonwoven fabric are, for example, the above-mentioned fiber materials.

The molding of the component in the mold is done by a

cohesive bonding of the fibers of the fiber material of the fiber layer or the fiber fleece with the liquid foam material and by

Pressing by means of the mold. The cohesive bonding takes place by means of the binder and / or by heating the

Fiber material and the liquid foam material in the mold.

In one possible embodiment, one or more inserts made of plastic may or may additionally be made, for example

Polyethylene terephthalate (PET), be provided. Such an insert, for example a plastic film, such as a polyurethane film, in particular allows a seat ventilation. This insert is expediently applied to the fiber layer or the fiber fleece and bonded to the fiber layer or the fiber fleece with a so-called adhesive tape and / or by hot riveting by means of a so-called hot riveting unit and / or by cold stamping. Then that will be

Introduced fiber material into the mold, in particular laid, and the component in the mold by introducing the foam material and then molding of fiber layer and foam layer formed so that the insert or the inserts integrated in the component, in particular partially or largely completely surrounded by the foam material, in particular recast or are. Due to a thereby partially different thickness of the applied and to be pressed fiber material than in the region of the insert or the inserts in comparison to a formation of a component without

Inserting parts is expediently used as a molding tool, a so-called cassette tool, wherein by means of one or more

Cassettes the shape of the mold can be changed. There are thus not several molds required, but that

Mold tool can be adapted to different shapes. This embodiment of the component has compared to the prior art, a lower weight, can be well dry after forming in the cassette tool and has a higher purity sort because, for example, the inserts, the fiber material and the

Foam material have the same plastic, for example polyester or polyethylene terephthalate (PET), while in the prior art, a woolen fleece is used, d. H. another material that the

Component 1 according to the invention. FIG. 1 shows a component 1 designed as a backrest cushion part, and FIG. 2 shows a component 1, designed as a seat part cushion, of a vehicle seat (not shown).

The formed in particular as a padding element for a vehicle seat component 1 is alternatively formed to a known nonwoven or upholstery, in particular a wool-fleece nonwoven or natural fiber pad from a fiber layer 1 .1 of a fiber material, at least on one

Surface side is provided with a foam layer 1 .2. In this case, the foam layer 1 .2, in particular a padding foam layer, completely on the at least one surface side on the fiber layer 1 .1 be applied. Alternatively, this can also be applied only partially.

The component 1 according to the invention comprises at least one

Fiber layer 1 .1, wherein the foam material of the foam layer 1 .2 at least partially or completely, in particular in the surface region of the fiber layer 1 .1 penetrated. In the finished state, the component 1 has a density in a range of greater than 90 g / l (= kg / m ³ ), in particular greater than 100 g / l or in a range of 100 g / l to 300 g / l.

In this case, the component 1 at a complete penetration of the liquid foam material in the fiber layer 1 .1 a high density, in particular a density in the range of 300 kg / m ³ . It only comes to a partial Penetration of the Schaummatehals in the fiber layer 1 .1 has the

Component 1 in the final state at least a density of greater than 90 kg / m ³ , in particular greater than 100 kg / m ³ .

For this purpose, the component 1 is formed from a fiber layer 1 .1, which is thermally treated such that a porosity at least in

Surface region of the fiber layer 1 .1 is adjustable. In this case, the fiber layer 1 .1, in particular a nonwoven fabric, as a roll or

Preformed plate material and be at least once or several times thermally pretreated.

In addition, the fiber layer 1 .1 may also be preformed.

The fiber layer 1 .1, in particular a nonwoven fabric is made of a

formed three-dimensional stochastically oriented fiber material.

For example, the fibrous layer 1 .1 has such a surface-open porosity open by thermal treatment that a liquid

Foam material of the foam layer 1 .2 up to a predetermined depth in particular controlled in the fiber layer 1 .1 can penetrate.

The fibrous material may comprise, for example, at least one modified and weldable thermoplastic, which is formed, for example, from a three-dimensional stochastically oriented polyethylene terephthalate (PET) or polyester or from a synthetic polymer, in particular from polylactide (PLA for short), which additionally comprises, for example, a thermosetting binder or one

FIG. 3A shows an enlarged sectional view of a component 1 in one possible embodiment. Due to the improved strength and Hardness of the component 1 as a result of in the fiber layer 1 .1 penetrated in the liquid state and then foamed there

Foam material of the foam layer 1 .2, the fiber layer 1 .1 over conventional padding elements for a vehicle seat have a smaller thickness. The component 1 shown as a cushioning element in Figure 3 preferably has a thickness D of less than 8 mm, in particular of less than 7 mm.

In this case, the fiber layer 1 .1 in particular has a thickness D1 of 0.5 mm to 5 mm. The foam layer 1 .2 has a thickness D2 of less than 6 mm. The thickness D2 of the foam layer 1 .2 also depends on the degree of penetration of the foam material into the fiber layer 1 .1.

The foam material of the foam layer 1 .2 penetrates the

Fiber layer 1 .1 completely, so the foam layer 1 .2 has a small thickness D2, for example, from 1 mm to 4 mm.

Advantageously, the fiber layer 1 .1 forms a back side of the component 1 and the foam layer 1 .2 a front side, in particular pad side of the vehicle seat. On the front of the component 1 can then be used to form the vehicle seat nor the seat of a

Seat cushion or a seat back are formed by, for example, still a cushioning material and a seat cover are arranged or only a seat cover is arranged.

The fiber layer 1 .1 advantageously has a constant

Basis weight, so that the manufactured component 1 is formed with a substantially constant basis weight.

The foam layer 1 .2 is formed in particular of polyurethane.

Alternatively, another suitable foam material, such as polyethylene and polypropylene, may be used. FIG. 3B shows an alternative embodiment of a component 1 with an enlarged sectional view through the component 1. The nonwoven fabric 1 .1 is provided with a coating 1 .3. The coating 1 .3 is particularly thin, in particular as a film formed on the nonwoven fabric 1 .1.

For example, the coating 1 .3 made of plastic, in particular made of polyethylene. The coating 1 .3 causes improved strength and hardness of the component 1, in particular the fiber layer 1 .1.

The coating 1 .3 is designed such that the

Foam material of the foam layer 1 .2 at least partially in the

Fiber layer 1 .1 can penetrate. The combination of coating 1 .3 on the fiber layer 1 .1 and partially in the fiber layer 1 .1

Penetrated foam material of the foam layer 1 .2 further increases the strength and causes the component 1 compared to conventional padding elements for a vehicle seat has a much smaller thickness.

FIG. 3C shows a further embodiment of a component 1 with an enlarged sectional view through the component 1.

In this case, an intermediate layer 1 .4 is provided between the fibrous web 1 .1 and the foam layer 1 .2. The intermediate layer 1 .4 is used for ventilation especially in the intended use. For this reason, the intermediate layer 1 .4, for example, cavities, in particular a capillary structure, for example, fine elongated cavities in order to form ventilation ducts in the intended use. Alternatively, the intermediate layer 1 .4 may also be formed as a film.

In addition, for example, on the outside of the

Surface side 01 of the foam layer 1 .2 facing away from the inside Surface side 02 openings 5, in particular ventilation vents, small holes or channels may be provided, which then with the

Capillary structure or the cavities in the intermediate layer 1 .4 are fluidly coupled to transport moisture from the surface side 01 and thus a seat or back surface away and to allow optimal air circulation.

For this purpose, the intermediate layer 1 .4 of a corresponding material, in particular a moisture-transporting material, such as a spacer fabric or polyurethane-based spacer fabric, and having a corresponding shape, in particular capillary structure,

Spacer fabric or spacer fabric, provided. For example, the intermediate layer 1 .4 has a thickness D3 of 1 mm. In particular, the

Interlayer 1 .4 a thickness D3 in a range of 0.5 mm to 2 mm.

The component 1 shown as a cushion element in FIGS. 3A, 3B or 3C preferably has a total thickness D of less than 8 mm, in particular less than 7 mm. The total thickness D may in particular be in a range between 5 mm and 12 mm, preferably 8-10 mm.

A process for the production is shown schematically in FIG. In a first method step S1, the fiber layer 1 .1 is thermally, for example by, for the production of the component 1

Heat supply T, treated in such a way that a predetermined porosity P1 .1, in particular at least on a surface side of the fiber layer 1 .1 a predetermined surface porosity is adjustable. In this case, the fiber layer 1 .1 can be partially thermally treated differently, so that different solid fiber layer regions arise. For example, areas with inserts 2 to 4 may become thermally stronger treated to achieve higher strength than in other areas.

In a second step S2, the fiber layer 1 .1 is provided with a liquid foam material, in particular polyurethane, at least on one surface side, preferably on the one with the predetermined porosity P1 .1. For example, for this purpose, the fiber layer 1 .1 as a preformed

Fiber fleece inserted in a mold. The liquid foam material is then introduced into the mold.

In this case, due to the permeable and open surface porosity of the fibrous layer 1 .1, the liquid foam material penetrates into its surface. Here, the predetermined and adjustable porosity P1 .1 is the

Fiber layer 1 .1 characterized as a result of the thermal treatment, by an adjustable number of pores, an adjustable size of the pores and / or an adjustable depth of the pores.

In this case, the foam material does not penetrate through the fiber layer 1 .1. The fibrous layer 1 .1 is produced with such a porosity P1 .1 that the foam material penetrates only on the surface side and does not penetrate.

The component 1 is formed by closing the mold and pressing, in particular hot pressing of the two layers, in particular the fiber layer 1 .1 and the foam layer 1 .2, finally. In this case, it can come to activate the liquid and penetrated foam material in the fiber layer 1 .1, so that this fiber layer 1 .1 is solidified after cooling and curing of the foam material.

Such a component 1 has a small thickness of less than 8 mm, in particular less than 7 mm. In addition, such a component 1 has a high density of greater than 90 g / l, in particular from 100 g / l to 300 g / l. The fiber layer 1 .1 can be thermally treated in the mold itself. For example, the fiber material in the

Molded are introduced, in particular scattered, and thermally treated and optionally preformed. Subsequently, the liquid foam material of the foam layer 1 .2 is introduced into the mold. Due to the given porosity P1 .1, this leads to a

Penetration of the foam material into the fiber layer 1 .1, so that the liquid foam material that has penetrated and thus, after activation of the foam, does not or only partially foams. Subsequently, the mold is closed and the component 1 is formed,

for example, hot pressed.

Alternatively, the fiber layer 1 .1 can be prefabricated and thus be in solid form, for example as a non-woven fabric in roll or mat product. The nonwoven fabric can be introduced into the mold and thermally treated there. Alternatively, the nonwoven fabric outside of

Forming be heat treated.

The introduced into the mold foam material of

Foam layer 1 .2 filled due to its high resilience a remaining space between the fiber layer 1 .1 and one of the shape of the back corresponding mold half of the mold without further action. The foam material thus fills the free volume of the mold and forms an outer cushion layer - the foam layer 1 .2 - and penetrates beyond the already in

Forming tool inserted or introduced fiber layer 1 .1.

Subsequently, both layers 1 .1, 1 .2 are pressed together and connected together. As a result, the component 1 in the finished final state has good rigidity, strength and resistance, and preferably nevertheless a softness. After the molding of the component 1, for example a backrest part or seat part, the component 1 is dried. In addition, the component 1 can still be punched or pinned. The pinching is advantageously carried out during drying, the punching is advantageously carried out after drying, wherein the component 1, for example, either pimped or stamped or, for example, partially pimped and partially punched. The drying is expediently carried out in a closed mold. Is expediently dried by an air supply to the component. 1

In addition, the component 1 with at least one or more

Depositors / n 2 to 4 are provided. As depositors 2 to 4 become

For example, fastener 2, nonwoven inserts 3 to 4 integrated into the component 1. In this case, the component 1 and the inserter (s) 2 to 4 are connected to one another by means of suitable connections, such as so-called adhesive tape or hot riveting unit.

The conventional production method results in an improved high strength and density of greater than 100 g / l with simultaneously small thickness D of less than 12 mm, in particular less than 10 mm or less than 8 mm of the component 1.
