Detailed Description
The decorative element 2 shown in fig. 1 and 2 is intended to be mounted in a motor vehicle. The decorative element 2 is for example selected from the following categories: door plant, instrument board, handrail and glove box door.
The decorative element 2 comprises a base 4 and a covering 6 covering the base 4. The substrate 4 defines the overall shape of the decorative element 2. The covering 6 defines the visual appearance of the decorative element 2. The covering 6 is a visible part of the decorative element 2. Preferably, the cover 6 covers the substrate 4 such that the substrate 4 is not visible.
The substrate 4 has a front surface 4A, and the cover 6 covers the front surface 4A. The front surface 4A of the base 4 faces the user.
The cover 6 has a front surface 6A oriented away from the substrate 4 and a rear surface 6B oriented toward the substrate 4.
The front surface 6A of the cover 6 is visible. The front surface 6A of the covering 6 defines a visible surface of the decorative element 2, which is also referred to as "surface a" in the field of motor vehicle decorative elements.
The decorative element 2 comprises at least one fastening element 8 of the hook and loop type for fastening the base 4 and the covering 6 together.
Each fastener 8 comprises a first fastening element 10 fixed to the base 4 and a second fastening element 12 fixed to the covering 6. The first fastening member 10 and the second fastening member 12 are configured to mechanically connect or snap to each other (or to each other) due to contact with each other.
In a known manner, the first fastening element 10 comprises a first support element 14 provided with a plurality of first engaging elements 16, the second fastening element 12 comprises a second support element 18 provided with a plurality of second engaging elements 20, the first engaging elements 16 and the second engaging elements 20 being configured to engage one another when in mutual contact.
Each first engaging element 16 is configured to be connected to one or more second engaging elements 20 when the first fastening element 10 and the second fastening element 12 are in contact with each other.
The first engaging element 16 of the first fastening element 10 and the second engaging element 20 of the second fastening element 12 of each fastener are configured to be connected to each other only by mechanical engagement or interaction.
Each fastener 8 is for example of the hook and loop type. In this embodiment, the first engagement element 16 is in the form of a hook or loop and the second engagement element 20 is in the form of a loop or hook, respectively.
In a variant, each fastener 8 is, for example, of mushroom and loop type. In this embodiment, the first engagement element 16 is in the form of a mushroom (i.e. a leg plus an enlarged head above the leg) or a loop, and the second engagement element 20 is in the form of a loop or a mushroom, respectively.
In a variant, each fastener 8 is, for example, of mushroom-mushroom type. In this embodiment, the first engagement element 16 is in the form of a mushroom and the second engagement element 20 is in the form of a mushroom.
In the example shown in fig. 2, each fastener 8 is of the hook and loop type.
As shown, in the preferred embodiment, the first engagement element 16 is in the form of a hook or mushroom and the second engagement element 20 is in the form of a loop.
These hook and loop fasteners 8 provide good fastening. Furthermore, fastening elements having hook-type or mushroom-type engagement elements are typically composed of a material that is more resistant to heat and pressure than the material of fastening elements having loop-type engagement elements. Thus, these fastening elements are more suitably overmoulded by the base 4, whereas fastening elements with loop-type engaging elements are less heat and pressure resistant and can be simply glued to the covering 6.
The first and second fastening elements 10, 12 are in the form of strips, each of the first and second fastening elements 10, 12 having a fastening face, wherein the fastening face of one fastening element is configured to be connected to the fastening face of the other fastening element when the fastening faces are joined to each other.
More specifically, the first support element 14 and the second support element 18 are each in the form of a flat belt, for example, with the first engaging element 16 being provided on the fastening face of the first support element 14 and the second engaging element 20 being provided on the fastening face of the second support element 18.
When the fastening surfaces are joined to each other, the first fastening member 10 and the second fastening member 12 are joined to each other by the first engaging member 16 and the second engaging member 20 engaging with each other.
The first fastening element 10 is arranged on the base 4, more particularly on the front surface 4A of the base 4, and the second fastening element 12 is arranged on the covering 6, more particularly on the rear surface 6B of the covering 6.
When the cover 6 is joined to the base 4, the first fastening elements 10 and the second fastening elements 12 are firmly fastened together, whereby the cover 6 is firmly fastened to the base 4.
The first fastening member 10 is fixed to the base 4 such that the first engaging member 16 is located on the front surface 4A of the base 4, and the second fastening member is fixed to the cover 6 such that the second engaging member 20 is located on the rear surface 6B of the cover 6, so that the first engaging member 16 and the second engaging member 20 are mutually engaged with each other when the cover 6 is bonded to the base 4.
The first fastening element 10 is fixed to the base body 4 such that the fastening face of the first supporting element 14 bearing the first engaging element 16 faces the covering 6, and the second fastening element 12 is fixed to the covering 6 such that the fastening face of the second supporting element 18 bearing the second engaging element 20 faces the base body 4.
The fixation is reliable. In fact, each first coupling element 16 engaged with the second coupling element 20 provides a lower retention force when fastening the first fastening element 10 with the second fastening element 12, but the multitude of first and second coupling elements 16, 20 engaged together produces a high retention force. Thus, the fastener/fasteners 8 provide a very secure fastening between the base 4 and the cover 6.
In an exemplary embodiment, the base 4 is a molded article, and the first fastening element 10 of each fastener 8 is secured to the base 4 by overmolding the base over the first fastening element 10.
The fixing of the first fastening element 10 to the base body 4 by over-moulding the base body 4 with the first fastening element 10 enables process time to be saved, since the first fastening element 10 is perfectly fixed to the base body 4 when the base body 4 is moulded, without the need for an additional step of fixing the first fastening element 10 to the previously produced base body 4. Furthermore, the manufacturing costs are reduced compared to gluing the first fastening element 10 to the substrate, since no adhesive is required.
Fig. 3 shows the overmoulding of the base 4 on the first fastening element 10 of each fastener 8.
The mold 22 includes a first mold portion 24 and a second mold portion 26 defining a mold cavity 28 therebetween.
The mould 22 comprises a respective retaining assembly 30, the retaining assembly 30 being adapted to retain each first fastening element 10 during moulding of the substrate 4 so as to enable the substrate 4 to be moulded over the first fastening element 10 without the first engagement element 16 being exposed to the substrate 4.
Each retaining assembly 30 comprises, for example, a retaining edge 32, the retaining edge 32 being intended to engage in a sealing manner the edge of the first supporting element 14 of the first fastening element 10 around the first coupling element 16, the retaining edge 32 delimiting a receiving cavity 43 for receiving the first coupling element 16.
In an exemplary embodiment, the first fastening element 10 is bonded to the first mold component 24. The matrix material, in a liquid or molten state, is then molded in the mold cavities 28 by covering the first fastening elements 10 of each fastener 8. Each retaining assembly 30 is disposed on first mold portion 24.
In the exemplary embodiment, the base body 4 is formed by injection molding. In this embodiment, the mold 22 is opened by moving the first mold portion 24 and the second mold portion 26 away from each other. The first fastening element 10 of each fastener 8 is placed in the open mould 22, the mould 22 is closed by bringing the first mould part 24 and the second mould part 26 close to each other, and the matrix material is injected into the closed mould 22 in a liquid or molten state.
In another exemplary embodiment, the matrix 4 is formed by compression molding. In this embodiment, the mold 22 is opened by moving the first mold portion 24 and the second mold portion 26 away from each other, the first fastening element 10 of each fastener 8 is placed in the opened mold 22, the matrix 4 material in a molten state is placed within the opened mold 22, and then the mold 22 is closed by moving the first mold portion 24 and the second mold portion 26 toward each other, the matrix 4 material thus being molded between the first mold portion 24 and the second mold portion 26.
The material of the base body 4 is, for example, a plastic material. The plastic material is, for example, polypropylene (PP), glass fiber reinforced polypropylene, in particular long glass fiber reinforced polypropylene (PP LGF), natural fiber reinforced polypropylene, polyethylene (P/E), in particular medium density polyethylene (P/EMD), Acrylonitrile Butadiene Styrene (ABS), and/or acrylonitrile butadiene styrene and polycarbonate mixture (ABS/PC). The material may be formed by injection or compression moulding.
The material of the matrix 4 consists for example of a fibre-reinforced material, i.e. a material in which fibres are integrated in a matrix.
The fibers may be natural fibers or synthetic fibers. The natural fibers may include wood fibers, hemp fibers, flax fibers, or kenaf fibers. The synthetic fibers may include polyethylene fibers.
The matrix may be a plastic matrix or a resin matrix, in particular a matrix consisting of polypropylene (PP). Due to the presence of fibres, this material is difficult to form by injection moulding, but can be formed by compression moulding.
In a particular embodiment, the material of the matrix 4 consists of a polypropylene matrix reinforced with natural fibers.
As shown in fig. 4, the second fastening element 12 of each fastener 8 is connected, for example, to the covering 6, more specifically to the rear surface 6B of the covering 6. This connection is obtained by providing an adhesive 36 between the covering 6 and the second fastening member 12, more particularly the support member 18 of the second fastening member 12.
The covering 6 is, for example, single-layered or multi-layered, in particular double-layered. The multi-layered covering 6 may include a base layer defining a rear surface 6B of the covering 6, covered by an appearance layer defining a front surface 6A of the covering 6. The base layer can, for example, consist of foam if it is desired to impart elasticity to the decorative element.
In an exemplary embodiment, the covering 6 comprises a layer defining a front surface 6A of the covering 6, the layer being composed of a material selected from the following classes: natural leather, synthetic leather, textiles, knits and plastic layers.
When the cover 6 is a single layer, the cover 6 may be composed of a layer composed of a material selected from the following classes: natural leather, synthetic leather, textiles, knits and plastic layers.
In a particular example, the covering 6 comprises a layer of natural leather or a layer of synthetic leather defining a front surface 6A of the covering 6. When the cover 6 is a single layer, the cover 6 may thus be composed of a natural leather layer or a synthetic leather layer. The leather layer gives the decorative element 2 a high quality impression.
The textile or fabric may be composed of natural or synthetic materials such as wool or plastic materials.
A manufacturing method for manufacturing a decorative element 2 comprises: obtaining a base 4 with at least one first fastening element 10 fixed on the base 4, and obtaining a cover 6 with at least one second fastening element 12 fixed on the cover 6, each second fastening element 12 forming, together with the matching first fastening element 10, a hook-and-loop fastener 8; the covering 6 is joined to the base body 4 such that the first fastening element 10 and the second fastening element 12 are fastened to one another (fig. 1 and 2).
A "mating" first fastener 10 is a fastening element configured to fasten to a second fastening element 12 when the first fastening element 10 and the second fastening element 12 are in contact with each other.
More particularly, the first fastening element 10 of the hook type is matched to the second fastening element 12 of the loop type, and the first fastening element 10 of the mushroom type is matched to the second fastening element 12 of the loop type or of the mushroom type.
In one embodiment, to provide a substrate 4 having at least one first fastening element 10 secured to the substrate 4, the method of manufacture includes, for example: the first fastening element 10 of each fastener 8 is placed in a mold 22 and the base 4 is then molded in the mold 22 such that the base 4 is molded over the first fastening element 10 of each fastener 8.
In another embodiment, to provide the substrate 4, the manufacturing method comprises, for example: the first fastening element 10 of each fastener 8 is adhered to the substrate 4, for example by means of an adhesive.
In one embodiment, to provide a covering 6 having at least one second fastening element 12 secured to the covering 6, the method of manufacture comprises: the second fastening element 12 of each fastener 8 is adhered to the covering 6, for example by means of an adhesive.
The present invention is not limited to the above examples. Other examples may be considered without departing from the invention.
As shown in fig. 1 and 2, the first fastening element 10 of each fastener 8 has a first engaging element 16 in the form of a hook, while the second fastening element 12 has a second engaging element 20 in the form of a loop.
This configuration is advantageous because the fastening elements having hook-type engagement elements are typically made of a more heat resistant material than the fastening elements having loop-type engagement elements. Thus, a fastening element having hook-type engaging elements is more suitable for matrix overmolding.
In other embodiments, the configuration of each fastener 8 is reversed. The first fastening element 10 of each fastener 8 has a loop-shaped first engagement element 16 and the second fastening element 12 has a hook-shaped second engagement element 20.
