Description
Technical Field
The present invention relates to a trim part, in particular for a motor vehicle, having an airbag chute structure, a base and a plurality of layers covering the airbag chute structure and the base.
Background
An airbag cover with an invisible tear line is known, for example, from document EP 1745989B 1. In this type of airbag cover, a local weakening is added in the leather decorative layer to ensure that the folding open of the airbag flap is controlled along the tear line. As has been determined, however, even with the aging of the decorative layer, it is difficult to ensure that the tear line (tear seam) remains invisible on the visible side of the airbag cover and does not become apparent over time.
SUMMERY OF THE UTILITY MODEL
The object of the utility model is to develop a decorative component with gasbag turns over board, it can not be discerned by vehicle passenger, wherein, after decorative component is ageing, the tear line of gasbag should remain invisible. The tear line is a line along which the airbag cover tears when the airbag cover is deployed, in particular when the airbag flap opens. Furthermore, it is an object of the invention to reduce the processing steps required for manufacturing decorative components. It is another object of the present invention to provide a method of manufacturing a decorative element having these features.
According to the invention, at least one of the above objects is achieved by a decorative part having the features of the main claim. Advantageous embodiments and further developments of the invention emerge from the dependent claims and the features described below.
A trim component for a vehicle interior is provided. The decoration part comprises:
-a substrate comprising an opening extending therethrough;
-an airbag chute structure disposed in the opening and mounted to the substrate, the airbag chute structure comprising: a wall forming a channel to guide deployment of the airbag; and a pivotable flap for closing the passage;
-a foam layer covering the airbag chute structure and at least a portion of the substrate around the airbag chute structure;
-a decorative layer having a front side facing the vehicle interior and an opposite rear side; and
a spacer layer arranged on the back of the decorative layer between the decorative layer and the foam layer.
The airbag chute structure also includes ribs that project into the foam layer.
The foam layer has a locally reduced thickness due to the ribs protruding into the foam layer. In the case of airbag deployment, the reduced thickness of the foam layer in the region of the ribs can support the opening of the pivotable flap. Thus, by providing ribs protruding into the foam layer, a tear line of the airbag housing may be defined without locally weakening the airbag housing (e.g., a perforation or cutting step). Alternatively, the foam layer may be formed directly on the substrate and the airbag chute structure by applying a foam-forming material thereon. Thus, fewer processing steps are required during the manufacture of the trim part compared to conventional trim parts having a locally weakened layer.
The foam layer may abut the ribs and completely cover the ribs. In some examples, the first portion of the foam layer extends over the rib. More specifically, the first portion of the foam layer may extend over the top side of the rib. The second portion of the foam layer is adjacent to the first portion. In particular, the second portion does not extend over the rib. More specifically, the second portion can abut a side edge of the rib. In some embodiments, it is contemplated that the two second portions are on opposite sides of the rib. The thickness of the first portion of the foam layer may be less than the thickness of a second portion of the foam layer adjacent to the first portion of the foam layer. The second portion of the foam layer may have a uniform thickness. In some embodiments, the second portion of the foam layer extends over the pivotable flap and has a constant thickness. At least that part of the foam layer which extends over the pivotable flap can have a constant thickness.
In some examples, the airbag chute structure can include a weakened portion that can extend along at least a portion of the pivotable flap. The weakened portion may define a perimeter of the portion of the flap. The rib may be located adjacent the pivotable flap and/or along at least a portion of the weakening. The weakened portion may be formed on a side of the airbag chute structure facing away from the vehicle interior and/or on a side facing toward the vehicle interior. For example, the weakening comprises one single groove, a plurality of perforations or at least one cut. Preferably, the weakened portion may be an in-mold tear seam, i.e., formed during molding of the airbag chute structure. In this way, any additional perforation or cutting step for providing the weakening can be avoided. The perimeter of the pivotable flap may define a tear line. For example, the weakening forms a leading edge of a pivotable flap.
The opening of the base may be defined by an inner peripheral edge of the base and may be completely covered by an airbag chute structure mounted to the base. The airbag chute structure can include means for engaging an edge of the opening to retain the airbag chute structure on the substrate when the airbag chute structure is inserted into the substrate. For example, the airbag chute structure can include a mounting flange that can extend circumferentially from the wall. The mounting flanges may engage corresponding mounting grooves formed in the base. In a preferred embodiment, the connection of the air bag chute structure and the base is foam-sealed. For example, the mounting flange may sealingly engage the mounting groove. Additionally or alternatively, dedicated seals may be envisaged to provide a foam-sealed connection between the base and the airbag chute structure.
In some cases, the ribs may be flush with the wall, particularly with the interior of the channel. The ribs may protrude from a surface defined by the pivotable flap and/or the base around the pivotable flap. In some embodiments, the rib is positioned along at least a portion of the tear line. For example, the rib may be adjacent to an airbag deployment area defined by the pivotable flap. In the case of airbag deployment, the ribs may be fixedly mounted relative to the base. Thus, the rib may be arranged such that the rib does not pivot with the pivotable flap in the event of airbag deployment. For example, the ribs may be securely connected to the wall. Preferably, the ribs and walls are integrally formed, for example, during the moulding process. The ribs may guide the airbag during deployment of the airbag into the vehicle interior. This may reduce foam collapse of the foam layer during release of the bladder. To avoid sharp edges, the ribs may have tapered or rounded ends facing the vehicle interior. This may reduce the visibility of the rib on the visible side of the trim member.
The substrate may be formed of a rigid plastic material, such as Styrene Maleic Anhydride (SMA), Polycarbonate (PC), ABS, PC/ABS, polypropylene (PP) or any other substrate material for vehicle interior applications known to those skilled in the art. In some cases, the substrate may include fibers or may be made of a mat containing fibers. The fibers may include natural fibers, glass fibers, mineral fibers, carbon fibers, synthetic fibers or cellulosic fibers. The fibers may also comprise combinations of the above fibers. Optionally, the material of the base is different from the material of the airbag chute structure.
The wall and the pivotable flap can be connected by a material connection in the region of the weakening and/or in the region of the rib. In some cases, the wall and pivotable flap are integrally formed, i.e. from a single piece during the molding process. The pivotable flap and the wall may be connected at a portion of the periphery of the flap by a living hinge along which the flap will pivot at the opening. Additionally or alternatively, the ribs and walls may be integrally formed. According to some embodiments, the wall, the rib and the pivotable flap are integrally formed.
The air bag chute structure as a whole may be embodied as a unitary structure. For example, the air bag chute structure may be molded from a plastic material, for example, during an injection molding process. In some cases, the airbag chute structure can be formed from a polymeric material, particularly a moldable thermoplastic material. Exemplary materials include Thermoplastic Polyolefins (TPO), thermoplastic elastomers (TPE), Thermoplastic Elastomer Olefins (TEO), and the like. Preferably, the pivotable flap sealingly covers the channel so that the air bag chute structure may be foam-sealed, i.e. when foam material is applied to the pivotable flap, and the rib-like foam does not leak into the channel. Airbag chute structures are commonly used in airbag deployment systems for vehicles. The airbag chute structure may include a housing formed from a wall and a pivotable flap. The housing typically includes an air bag and dedicated components for its operation.
The decorative layer may be made of natural leather. In particular, the decorative layer may be a single layer of leather. Other materials, such as snow slush skin, are also contemplated. Furthermore, the spacer layer may be a textile layer, preferably a woven textile.
In an exemplary embodiment, the decorative layer and/or the spacer layer have a constant thickness. In this case, for example due to temperature changes, air humidity, drying, shrinkage or exposure to sunlight, it is possible to avoid significant local changes in the surface of the decorative layer on ageing, the position of the airbag remaining invisible for a longer period of time due to the constant thickness of the decorative layer and the spacer layer lying thereunder. The spacer layer arranged between the decorative layer and the foam layer can thus stabilize the decorative layer and allow the entire decorative layer to be designed in a thin manner, so that a controlled tearing of the airbag cover can be ensured. A constant thickness of the decorative layer and/or the spacer layer is easier to achieve than a local weakening in the layer, which extends along the tear line, because an additional processing step may be required for the local weakening of the decorative layer and/or the spacer layer. Thus, due to the constant thickness of the decorative layer and/or the spacer layer, expensive and time-consuming steps in the machining or machining process can be avoided.
The decorative layer and the spacer layer may be bonded into a composite, for example, by using an adhesive. The composite may have a lower tear force than another decorative layer of the same material as the decorative layer described above, e.g., leather, which is the same thickness as the composite. The composite need not be locally weakened to finely define the tear line and there is no need for a specially designed tear location.
Thus, neither the decorative layer, the spacer layer, nor the foam layer need to be locally weakened to deploy the airbag. It is sufficient if the airbag chute structure exhibits a local weakening along the tear line. In case the decorative layer is natural leather, the thickness of the layer is preferably reduced by detaching the natural leather.
The advantage when applying the compound is also a further processing, whereby the decorative part is laminated. Since preferably neither the leather decorative layer nor the spacer layer are provided with a local weakening, it is in particular also not necessary to carefully apply a weakened tear seam between each other, for example by making a perforation or a cut of the upper layer coincide with a weakening of the lower layer. The composite can thus be applied in a simple manner to the foam layer and/or to the airbag chute structure and/or to the substrate.
As to how thin the decorative layer to be designed in the mentioned partial areas may depend on the quality of the leather applied. The thickness of the decorative layer is chosen such that tearing of the airbag is ensured when it is released. In a typical design, the thickness of the decorative layer is 0.8mm at the maximum. Preferably, the spacer layer has a thickness of at least 0.4mm, more preferably at least 1.2 mm. The thickness of the decorative layer may for example be between 0.5mm and 1.5 mm. For this purpose, the thickness of the starting material of the decorative layer can be reduced uniformly. A spacer layer of typical design may have a thickness of, for example, between 1.2mm and 4.5 mm. The first portion of the foam layer may have a thickness of at least 1mm and the second portion of the foam layer may have a thickness of at least 2 mm. The first portion and/or the second portion may have a maximum thickness of at most 10mm and 15mm, respectively. The thickness of the first portion depends on the length of the ribs protruding into the foam layer. The ribs may protrude into the foam layer at least 0.5mm and/or at most 6 mm. Typically, the thickness of the second portion of the foam is between 5mm and 10mm, the thickness of the first portion of the foam is between 3mm and 6mm, and the ribs project into the foam layer by 2mm to 4 mm.
Alternatively, the spacer layer can have at least one preferred tearing direction along which tearing is easier than along the other directions, wherein the tear seam in the airbag chute structure extends at least in part parallel to the preferred tearing direction or parallel to one of the preferred tearing directions. In this way, controlled tearing of the airbag cover along the tear seam is facilitated. If the tear seam (tear line) is generally U-shaped or H-shaped, the spacing layer or the composite can be arranged or laminated in such a way that the seam extends almost anywhere parallel to one of the preferred tear directions. Typically there will be one preferred direction of tearing, but in some embodiments there may be two preferred directions perpendicular to each other, for example two directions defined by the directions of the warp and weft.
The spacer layer may be made of a different material than the decorative layer. Thus, the spacer layer preferably does not consist of leather. In a particularly preferred embodiment, the spacer layer may be a textile layer, for example a woven fabric (see also above). The direction of the warp and/or weft threads of the woven fabric may then define a preferred tearing direction, respectively, along which the distance layer tears more easily than in other directions. As long as the fabric is oriented such that the tear seam runs at least partially parallel to the warp threads and/or parallel to the weft threads, it is possible to ensure particularly well that the decorative part splits in a controlled manner along the tear seam. In the case of a released airbag, to allow a correspondingly controlled tearing of the airbag cover.
Thus, according to the decorative layer described above, the spacer layer and/or the foam layer may not be partially weakened by cutting or perforating the layers.
The present invention also relates to a method for manufacturing a decorative part, in particular to a method for manufacturing a decorative part as described above. The method comprises the following steps:
-providing a substrate comprising an opening;
-forming an air-bag ramp structure during the moulding process;
-arranging an airbag chute structure in the opening of the base;
-bonding the decorative layer and the spacer layer into a composite;
-forming a foam layer on the substrate and the airbag chute structure, and
-connecting the foam layer and the spacer layer of the composite.
In case the decorative layer is made of natural leather, the thickness of the decorative layer may be reduced to a constant value, preferably less than 0.8mm, before the decorative layer is bonded to the spacer layer. The thickness of the leather layer can be reduced by separating the leather layers.
In particular, the weakened portion of the airbag chute structure may be provided during the molding process.
The decorative layer may be bonded to the spacer layer by using an adhesive. The composite can be arranged such that the preferred tearing direction of the spacing layer extends at least in a cross section parallel to the tear seam.
The foam layer may be formed in different ways. In one embodiment, the foam-forming material is injected between the composite and one side of the substrate and the other side of the airbag chute structure, i.e. into the cavity formed by the composite, the substrate and the airbag chute structure. Thereafter, the foam-forming material cures and bonds to the composite, the substrate and the bladder ramp structure, thereby forming a foam layer. The trim part obtained in this way may be referred to as a foam-in-place (FIP) trim part.
In an alternative embodiment, the foam-forming material is applied to the substrate and the airbag chute structure. Then, a foam layer is at least partially formed. The composite may be applied to a foam layer, a partially formed foam layer or a foam forming material.
Therefore, a decorative member satisfying the above requirements can be obtained by the above method with a small force. Any feature described separately with respect to the trim component may also be used in the method, and vice versa.
Drawings
While multiple embodiments are disclosed, still other embodiments of the present invention will become readily apparent to those skilled in the art from the following detailed description, which shows and describes illustrative embodiments of the invention. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not as restrictive.
FIG. 1 illustrates a plan view of a portion of a trim component with an airbag chute structure installed therein; and
FIG. 2 shows a partial cross-section of the trim component of FIG. 1 taken along line A-A.
Detailed Description
Hereinafter, an exemplary embodiment will be described with reference to fig. 1 and 2 at the same time. FIG. 1 shows a plan view of a portion of a trim component 1 of a vehicle in which an airbag chute structure 3 is installed, while FIG. 2 shows a partial cross-section of the trim component of FIG. 1 taken along line A-A.
The trim part 1 can be part of an instrument panel, a center console, a door panel or a seat in the interior of a vehicle, in particular in the passenger compartment. The trim part comprises a rigid substrate 2 (carrier 2) having an opening 4 extending therethrough. The rigid substrate 2 may be formed of a plastic material, for example, Styrene Maleic Anhydride (SMA), Polycarbonate (PC), ABS, PC/ABS, polypropylene (PP) or any other substrate material for vehicle interior applications known to those skilled in the art. In some cases, the substrate may include fibers or may be made of a fiber mat.
The opening 4 of the base is configured to receive the airbag chute structure 3. Thus, the airbag chute structure 3 is arranged in the opening 4 and is mounted to the inner peripheral edge of the opening 4. In particular, the airbag chute structure 3 may include: a circumferential mounting flange 16 which mates with a corresponding mounting recess 17 formed in the base 2. The flange 16 and the groove 17 are firmly fixed to each other, for example by means of adhesive, screws or other suitable attachment means (not shown). The mounting flange 16 may sealingly engage the mounting groove 17 such that the connection therebetween is foam-tight.
The airbag chute structure 3 further includes a housing 18, the housing 18 being adapted to house an airbag (not shown) and various components for operating the airbag in the event of a vehicle collision. The air-bag chute structure 3 may be moulded from a plastics material, for example, in an injection moulding process. In some cases, the airbag chute structure can be formed from a polymeric material, particularly a moldable thermoplastic material. Exemplary materials include Thermoplastic Polyolefins (TPO), thermoplastic elastomers (TPE), Thermoplastic Elastomer Olefins (TEO), and the like. The material may be mixed with fillers that alter the melting temperature, flexibility, stiffness and other properties of the material. It is envisaged that the material of the air-bag chute structure 3 is different from the material of the substrate 2. For example, the airbag chute structure 3 may be formed of a more flexible material than the rigid substrate 2.
The housing 18 of the air-bag chute structure 3 comprises a wall 5, which wall 5 forms a channel 6 for guiding the deployment of the air-bag; and a pivotable flap 7 for closing the passage 6 in the normal operating state of the vehicle (i.e. when the airbag is not released). The wall 5 extends from the side facing the interior of the vehicle. The pivotable flap 7 is pivotably connected to the wall 5 on one side by a hinge portion (not shown), for example a living hinge, and at least partially covers the opening 4 in the base 2. In addition, the mounting flange 16 extends away from the wall 5 and the channel 6. In the embodiment shown, there is a single U-shaped door flap 7. Alternative flap arrangements known to those skilled in the art, such as an "H-shaped" flap arrangement with two door flaps, may also be used. Other flap arrangements are also contemplated.
The air bag ramp structure 3 further comprises a rib 11 extending substantially orthogonally from the plane defined by the pivotable flap 7. As shown in fig. 2, the ribs 11 are flush with the side of the wall 5 facing the channel 6. For example, the ribs may form an extension of the wall 5. The rib 11 may be adjacent to an airbag deployment area 19 defined by the pivotable flap 7. The rib 11 is therefore arranged such that the rib 11 does not pivot together with the pivotable flap 7 in the event of airbag deployment. During deployment of the airbag, the airbag is guided by the channel 6 and the ribs 11 into the passenger compartment. The ribs 11 may also minimize or eliminate foam collapse of the foam layer 8 during balloon release.
The wall 5 and the pivotable flap 7 can be glued to one another by a material connection. More specifically, the wall 5 and the pivotable flap 7 can be connected by a material connection in the region of the rib 11 and/or in the region of the weakening 12. In this way, a foam-tight connection can be achieved between the wall 5 and the pivotable flap 7. The wall 5, the rib 11, the flange 16 and/or the pivotable flap 7 may be formed of the same material. In particular, the wall 5, the rib 11, the flange 16 and the pivotable flap 7 may be integrally formed in a moulding process. More specifically, the airbag chute structure 3 as a whole may be embodied as a unitary structure formed in an injection molding process to minimize the number of manufacturing steps, reduce the number of parts, and reduce complexity.
The airbag chute structure 3 includes a weakened portion 12 extending along a tear seam 13 (tear line). As the tear line 13 defines the pivotable flap 7, the rib 11 is positioned along the tear line 13 and follows its course. For example, the weakening 12 comprises a groove having the same course as the tear seam 13, e.g. a U-shaped groove corresponding to the U-shaped course of the tear seam 13 of fig. 1. The weakening 12 may alternatively comprise a plurality of slits, cuts or perforations arranged along the course of the tear line 13. In the case of an H-shaped tear line, two pivotable flaps are envisaged. In this case, the two ribs may be located respectively at the sides of the H-shaped tear line, i.e. not at the middle strip of the H. In any case, the ribs can therefore be arranged such that they do not pivot together with the pivotable flap in the event of airbag deployment.
Preferably, the weakened portion 12 is an in-mold tear seam, but may alternatively be formed by cutting or perforating the shell 18 of the airbag chute structure 3 after it is molded. As shown in fig. 2, the weakened portion 12 may be formed on a side facing away from the vehicle interior. Additionally or alternatively, the weakened portion 12 may also be formed on the side facing the vehicle interior.
The trim part 1 further comprises a foam layer 8, a decor layer 9 and a spacer layer 10.
The foam layer 8 covers the airbag chute structure 3 and at least a portion of the substrate 2 around the airbag chute structure 3. In an exemplary embodiment, the foam layer 8 may comprise Polyurethane (PU) or other suitable material. As shown in fig. 2, the ribs 11 extend into the foam layer 8. The foam layer 8 abuts the ribs 11 and completely covers the ribs 11. A first portion 14 of the foam layer 8 extends over the rib 11, wherein said first portion 14 of the foam layer 8 has a thickness which is smaller than a thickness of a second portion 15 of the foam layer 8 adjacent to the first portion 14 of the foam layer 8. Due to its reduced thickness, the first portion 14 is more prone to rupture during balloon release than the second portion 15. Even if the foam layer 8 protrudes into the gap between the mounting flange 16 and the base 2, the channel 6 and the areas on the back of the base 2 and the air bag chute structure 3 are free of foam. At least that part of the foam layer 8 which extends over the pivotable flap 7 can have a constant thickness.
Typically, the materials of the decorative layer 9 and the spacer layer 10 are different from each other. For example, the decorative layer 9 is made of natural leather, while the spacing layer 10 may be a textile layer 10, such as a woven fabric. Decorative layer 9 and fabric layer 10 are bonded by an adhesive and together form composite 20. Both the decorative layer 9 and the spacer layer 10 have a uniform thickness. In a typical design, the thickness of the decorative layer is at most 1.2 mm. Preferably, the spacer layer has a thickness of at least 1.2 mm. The thickness of the decorative layer may for example be between 0.4mm and 0.7mm, for example 0.55 mm. For this purpose, the thickness of the starting material of the decorative layer can be reduced uniformly, for example by detaching a leather layer. A spacer layer of typical design may have a thickness of, for example, between 1.3mm and 4.5 mm.
The spacer layer 10 is bonded to the back of the decorative layer 9, while the front of the decorative layer faces the vehicle interior. The foam layer 8 is attached to the back of the spacer layer 10. In some cases, the pivotable flap 7, the foam layer 8, the decorative layer 9 and the spacer layer 10 covering the airbag channel 6 are referred to as an airbag cover. The distance layer 10 comprises a woven fabric whose warp and weft define two preferred tearing directions, which are substantially orthogonal to each other. The blank layer 10 tears more easily in these tearing directions than in other directions. The U-shaped tear lines 13 each extend parallel to one of the preferred tearing directions.
The invention also relates to a method for manufacturing a decorative part 1 as described above. Reference is again made to fig. 1 and 2 and the detailed description above.
As a first optional step, the thickness of the leather layer may be reduced to a constant value, preferably less than 0.8mm, so as to form decorative layer 9. Decorative layer 9 may be bonded to spacer layer 10 by an adhesive, thereby forming composite 20.
Furthermore, a substrate 2 is provided. The airbag chute structure 3 is integrally formed in the injection molding process. In particular, the weakened portion 12 may be provided in the airbag chute structure 3 during the molding process. Subsequently, the airbag chute structure is arranged in the opening 4 of the base 2 and mounted thereon.
According to the implanted form, the trim part is a FIP (foam in place) part. In these embodiments, the foam layer 8 is formed by injecting a foam forming material between the substrate 2 and the spacer layer 10 and between the air bag chute structure 3. The composite 20 can be aligned such that the preferred tearing direction of the distance layer 10 extends at least in a cross section parallel to the tear line 13. During manufacture, the foam layer 8 is typically formed by injecting a foam-forming material into the cavity defined by the spacer layer 10 and the substrate 2 and the air-bag chute structure 3. During curing of the foam-forming material, the foam layer 8 is formed and bonded to the spacer layer 10, the substrate 2 and the airbag chute structure 3.
In an alternative embodiment, the foam-forming material is applied to the base 2 and the air bag chute structure 3. Subsequently, the foam layer 8 is formed. The composite 20 may be applied to the foam layer 8, to the partially formed foam layer 8 or to the foam-forming material during the formation of the foam layer 8. Furthermore, the composite 20 can be aligned such that the preferential tear direction 10 of the spacing layer extends at least in a cross section parallel to the tear line 13.
Various modifications and additions may be made to the exemplary embodiments discussed without departing from the scope of the present invention. For example, although the embodiments described above refer to particular features, the scope of the present invention also includes embodiments having different combinations of features and embodiments that do not include all of the described features.
