    Interior cover for a vehicle roof
    The present invention relates to a InnenveiWeldungeteil for a vehicle roof and in particular a so-called. Headliner panel for a vehicle with a sound-absorbing effect. A conventional trim panel for the roof trim of a motor vehicle is known from the official document WO 99/40567 A1. The therein referred to as surface acoustic absorber «characterized by a broad absorption spectrum. However, this requires a complex mechanical design with a high material usage. This in turn results in a high weight and the need to attach the Flä-10 chenabsorbers at several points of Rahhaus. One of the contemporary approaches corresponding cantilever headliner panel can be realized in this way difficult.
    An official publication WO 00/068039 A1 discloses a recording section for different areas in a motor vehicle and with a similar acoustic effect. Furthermore, DE 10 2004 015 472 A1, DE 102 48 266 A1, DE 101 52 759 A1, DE 41 23 593 A1 and EP 1 233 686 B1 are known as state of the art.
    Object of the present invention, it is against dam described background to provide a Verklei-training part for the headliner of a motor vehicle, which combines a good Scball insulation effect with a low weight and can be manufactured inexpensively with the known procedural 20 ren.
    This object is achieved by a trim panel for the headliner of a motor vehicle having the features specified in claim 1. Further advantageous embodiments and further developments are defined in the subsequent subclaims.
    The core idea of the invention here is to provide at least one passage opening in the support layer at least in a partial region 25 of the trim panel in order to improve the coupling of the volume in the interior space of the vehicle to the damping layer. Through the at least one passage opening in the carrier layer, sound which is generated by the motor vehicle and / or the surroundings of the motor vehicle is introduced into the damping layer 20/06/2011 07:47

    704972AT - 2 - so that the sound-absorbing properties of this layer can affect the interior acoustics of the vehicle.
    Here, the InnanauGkleidung example, a so-called headliner for a motor vehicle. The carrier layer is constructed stably so that a self-supporting suspension of the inner lining, with exclusive attachment to the edge regions of the carrier layer, is possible. Thus, it is sufficient to attach the inner lining to only a few points of the body of the motor vehicle, with advantages in terms of weight and manufacturing effort. For further stiffening, the carrier layer may have a three-dimensional shape. For the purpose of stiffening, a projection extending over a substantial part 10 of the length or the width of the carrier layer or a correspondingly configured bead may be provided.
    In a preferred embodiment of the invention, a plurality of passage openings with a comparatively small cross-section is provided, so that there results a planar perforation of the carrier layer. Such a perforation provides a carrier layer which has an acoustically optimized (ie reduced) flow resistance, so that an acoustically advantageous introduction of the sound into the damping layer is made possible. In contrast to only one large through-opening or only a few larger through-openings, the flat perforation does not appreciably reduce the intrinsic stiffness of the carrier layer. The particular acoustic effect of the inner lining according to the invention results from the interaction of the perforated carrier layer with the damping layer and the subsequent limitation of the acoustically effective volume by an adjacent body boundary, such as a vehicle roof. This arrangement acts as a chamber for a plurality of juxtaposed Helmholtz resonators and is also referred to in the literature as a hole-surface resonator. For sound waves impinging on the perforation from the vehicle interior, the effective frequency of which corresponds to the resonance frequency, this results in a maximum coupling to these Helmholtz resonators. As a result, the fast in the through holes and the adjoining environment above and below maximum. This Schnellema-30 maximum is deprived by the lying above the support layer damping layer with their increased flow resistance to a high degree of energy. This is a damping 20/06/2011 07:48

    704972AT -3- the sound intensity is accompanied by the adjacent body boundary, for example, the vehicle roof, returning sound energy is greatly reduced.
    In a preferred embodiment of the invention, the carrier layer is configured as a sandwich component with at least two layers, wherein the at least one passage opening is located in the core layer, while the underside air-permeable cover layer has no passage opening. Thus, a total of "acoustically open" support layer (made of core layer and cover layer) is given, which binds the damping layer to the interior of the motor vehicle. Due to the volumächlge cover layer without Durchgartgsöffnung is eireicht that the at least one through hole does not appear at the unsurfaced decorative 10 schlchl. As a result, a uniform and uniform appearance of the ink discharge over the entire surface of the carrier layer is achieved.
    In a further advantageous embodiment of the invention, the damping layer is provided only in one area or only in several areas of the inner lining. Consequently, the passage openings are introduced only in this area or in these areas of the inner lining. This reduces the expense of producing the inner lining and increases the tensile strength of the support layer. The areas with a damping layer are primarily determined by the acoustic effectiveness. Another criterion is the installation space for the damping layer present on the inside of the vehicle roof. In an embodiment of the invention, the passage openings have a circular cross-section. Such passage openings are to be introduced in a simple manner. Their diameter is for example about 1.5 mm to 9 mm. Of course, in addition to the circular shape and other Querschnlttsformen possible. The hole area ratio is to be tuned to the specific installation ratios and may, for example, assume values of about 10% 25 to about 70%, for example 25%.
    The production of Durchgangsöffhungen or holes, for example, by cutting, drilling. Punching, thermal processes, etc. take place. When using a thermal process (for example, reader beam cutting) in a thermoplastic Kunststoffma material can be done by melting the tailor edges an additional stiffening of the carrier layer. The passage openings can be introduced over the entire surface of the carrier layer for reasons of simplifying the production. Alternative 20/06/2011 07:48

    704972 AT -4- the through holes can be limited to those areas in which a damping layer is disposed at the top of the carrier layer. If the passage openings are introduced by punching, the punching device can be designed, for example, as a punch or as a roller. In one possible embodiment of the invention, in those embodiments of the invention in which the sound-absorbing layer is arranged only in a partial region of the supporting layer of the inner lining, the upper side of the supporting layer not covered with the sound-absorbing layer is provided with an air-impermeable layer, too Here to prevent contamination of the decorative layer. Also, the transition between the air-impermeable layer at the top of the sound-absorbing layer and the air-impermeable layer at the top of the support layer is made airtight to prevent air leakage.
    In the case of an air-impermeable layer attached directly to the rear side of the carrier layer, in which the at least one region with at least one through-opening (preferably with a plurality of through-openings - perforation *) is recessed, an additional soundproofing results , higher frequency range. For a higher-frequency shielding radiation whose effective wavelength is approximately four times the distance between the carrier layer and the adjacent body border (for example the vehicle roof), the air-permeable carrier layer acts in the same manner as the above-mentioned damping layer. Thus, the invention Innenausldeidung realizes a good sound attenuation in two different frequency ranges. For the typical application in a motor vehicle, the low-frequency absorption is tuned to the engine-induced sound, while the higher-frequency absorption preferably designed for tire and wind noise wild. In one embodiment of the invention, a cover layer is provided on the carrier layer both on the underside and on the upper side. This symmetrical sandwich construction achieves a high rigidity of the carrier layer.
    The at least one cover layer of the carrier layer is formed, for example, by a nonwoven which is reinforced with natural fibers. This results in an improved Recydingfä-30 ability of the carrier layer. When selecting natural fibers Care should be taken to ensure that they do not obstruct air permeability. For example, sisalfa- 20/06/2011 07:48 are suitable for this purpose

    The damping layer consists, for example, of an open-pore PUR foam with a comparatively low density. Alternatively, the damping layer can also be formed from a nonwoven web of natural and / or synthetic fibers, as well as another type of lightly packed textile material or mixed forms thereof (fiber or mixed fiber fabrics). The sound absorption in the damping layer is primarily not by their mass, but by the sound-absorbing properties of the foam or the fleece or Tex-tllmaterials by the materials mentioned counteract the passage of the air flow a 10-th flow resistance, the sound waves in the cavities of the foam or of the nonwoven or of the textile material thus "dead run" *.

    704972AT 7 rear section above the rear seats 6 are arranged. An air-impermeable barrier layer 80 attached to the back of the backing layer 30 is cut out in these areas 38.40. The barrier layer 80 is preferably formed as a nonwoven impregnated with plastic of *, which is surface-connected to the carrier layer 30 and prevents the passage of air from the interior into the space between the Veikleidungsteii and the vehicle roof This serves the known purpose of to improve an increased fouling of the decorative layer 56 due to a Partlkelablagerungen when flowing through the Veddel-tion part with contaminated ambient air during closing and opening the vehicle doors. Particularly advantageous in the present case, the barrier layer in the areas 10 36,40 not only identical to the perforation 70 broken through but completely in this
    Area recessed. As a result, the carrier layer 30 of the message part within the regions 36, 40 still has an air permeability which extends beyond the passage cross section of the perforation 70
    In the areas 38 and 40, a damping layer 32 is arranged as sound insulation on the interior trim part 2 on the top side. Preferably, this damping layer 32 is designed as a loose fleece or another lightly packed textile material which opposes the passage of an air flow with a certain flow resistance. The damping layer 32 may, for example, be formed as an open-pored PUR foam and has a comparatively large overall height H. Due to the relatively low density 20 of the damping layer 32, nevertheless, a relatively low weight of the acoustically effective Dämpfiingsechicht 32 results.
    The structure of the interior trim part 2 is shown in more detail in FIGS. 3 and 4. FIG. 3 shows the structure of the carrier layer 30 on the left, outer edge of the vehicle, to which the partial region 40 tapers toward the middle of the Fehrzeugmitte. Decisive for the Eigenstabll-25 did the carrier layer 30 is their structure as a surface laminate. The surface laminate comprises at least a first layer 50, for example of a PUR foam, and a second layer of a fiber mat, preferably a natural fiber mat. In the illustrated embodiment, the surface laminate additionally comprises a top and bottom cover layer 52. The two cover layers 52 and 54 are formed, for example, by an air-permeable nonwoven reinforced with sisal fibers. The antifoam layer 30 comprises the first layer 50 and the cover layers 52 and For example, 54 has a thickness D of about 6 mm in total.

On the outside, the decorative layer 56 has, for example, a textile fabric 57. On the inside of the textile fabric 57, a foam backing 58, for example with a PUR foam, is provided to provide a so-called " soft-touch effect " to reach. The thickness 5 d of the decorative layer 56 is for example about 3 to 4 mm.
    The sectional view of Fig. 4 shows the course of the interior trim part 2 over the width of the motor vehicle. The interior trim part 2 extends below the vehicle roof 60, which consists for example of a light metal material or of a carbon fiber reinforced plastic. The interior trim part 2 has partial areas 36 and 40 with a width B. In Flg. 4, the portion 40 is shown in cross section. The schematic representation of the Flg. 2 is to be understood that the partial area 40 (as well as the partial area 38) is not formed as a full-surface cutout, but aulweist has a plurality of circular Durehgengsöffnun gene which evenly or non-uniformly over the surface of the portion 40 (and 15 corresponding to the portion 38th In other words, the interior trim part 2 is provided with a perforation 70 in the subregions 38 and 40. As shown in Fig. 1, two separate cushioning layers 32 are provided in the subregions 36 and 40, respectively.
    The passage openings or holes of the perforation 70 are matched to the acoustic Eigen-20 sheep of the relevant motor vehicle in terms of diameter, number, spacing and distribution. The holes of the perforation 70 are in the drawing represent Flg. 2 not drawn over the entire surface of the subregions 38 and 40, but distributed in the actual embodiment over the entire surface of the subregions 38 and 40. As can be seen in particular from FIG. 3, the holes of the perforation 70 only extend within the carrier layer 30. The top and bottom cover layers 52 and 54 are permeable to air and have no perforation 70.
    As previously described, a barrier layer 80 is provided at the top of the carrier layer 30. In subregions 38 and 40, there is no barrier layer 80. Alternatively, the barrier layer 80 is present prior to the introduction of the perforations 70 in the portions 38 and 40, but is removed locally with the introduction of the perforation 70, respectively, to produce the air patency. 20/06/2011 07:50

    It is particularly advantageous if the barrier layer 80 in the subregions 38 and / or 40 is not only perforated according to the perforation {perforated openings 70), but is completely recessed in these regions. This results in an improved air permeability, which extends beyond the passage cross section of the through-openings 70. S Likewise, an air-impermeable barrier layer 82 is provided on the upper side of the damping layer 32. Also, this barrier layer 82 is impermeable to air and prevents the intensive air exchange between the passenger compartment and the space to the vehicle roof through the decorative layer 56 of the Verkleidsteiis. The connection between the two barrier layers 80 and 82 is designed airtight. For example, the edge region R of the damping layer 32 is pressed together and adhered to an adhesive layer 84 mH of the upper side of the carrier layer 30, more precisely to the barrier layer 80.
    The areas 3Θ and 40 in which the perforation 70 and the damping layers 32 are located are as large as possible. In the present example, the width B of the areas 38 and 40 is about 800 to 900 mm. The length L1 or L2 of the areas 38 and 40 15 is about 350 or 450 mm. As a result of the interior mirror module 14, a reduced length L3 of about 260 mm is given in the center region.
    In principle, it is advantageous if the regions 38 and 40 provided with perforation together occupy an area of at least 0.5 m 2. The regions 38 and 40 are preferably rectangular or trapezoidal. As can be seen in particular from the illustration of FIG. 4, the interior trim part 2 according to the invention requires a comparatively large installation space below the vehicle roof 60. This space requirement is primarily due to the relatively high height H of the damping layer 32. The height H is for example about 20 to 30 mm. Despite the comparatively large required height of the InnenvertdeklungsteHs 2, the Innenverkiei-25 tion part 2 has a relatively low weight because of the relatively low density of the shadow-absorbing layer 32 as a whole.
    The space required is not available over the entire surface of the vehicle roof 60. In particular in the region of the projection 16, in which there is a transverse bow or a bead for reinforcing the vehicle roof 80, the required installation space 30 is not provided. For this reason, the attenuator 32 is divided into two sections as shown in Figs. Also in the Randberaichen of the vehicle roof 60 is the 20/06/2011 07:51

    As a rule, since the damping layer 32 is available as a plate product with a constant material thickness, the regions with reduced installation space can not be provided with a damping layer 32. Decisive for the perception by the vehicle occupants, however, is that the attenuation layer 32 is mainly "close to the head". is arranged to the vehicle occupants
    In summary, the invention can be described as follows: An inventive interior trim part 2 for a vehicle roof has a carrier layer 30, which is provided on the underside with a decorative layer 56. Above the carrier layer 30, a damping layer 32 is provided. According to the invention, the carrier layer 30 in at least one partial area 38, 40 has a planar perforation with a plurality of passage openings 70 in order to couple the interior of the vehicle to the damping layer 32
    The particular acoustic effect of the above-described fairing results from the interaction of the perforation 70 in the areas 38,40 of the carrier layer 30, the thereto after installation above subsequent damping layer 32 and 15 the overlying roof panel of the vehicle body. The air layer between the roof plate and the perforation partially in the damping layer 32 and partially above it. In the areas 38, 40 of the carrier layer 30 acts as a chamber for a number of adjacent Helmholtz resonators. This arrangement is sometimes referred to in the literature as Lochflächenresonator, the resonant frequency fa can be a-20 times determined by the formula given below (from: Schalttechnisches Taschenbuch, Helmut Schmidt, VDf-Verlag Dusseldorf, 1996): U s 5400
    Therein f, the hole area fraction, r the Lochradlus, d the perforated plate thickness and a the chamber height respectively in centimeters (cm). The effective frequency of a plane sound wave that does not radiate deadly on the surface of the lattice part is to be understood as the frequency corrected by the angle of incidence. For coming from the vehicle interior to the perforation in the areas 38,40 sound waves whose effective frequency corresponds to the resonant frequency, there is a maximum coupling to these Helmholtz resonators Thus, the fast in the 20/06/2011 07:51

    7Q4972AT - 11 - Openings of the perforation and adjoining surroundings above and below maximum. This fast maximum is strongly deprived of energy by virtue of the damping layer 32 lying above the carrier layer 30 in a manner known per se, owing to the resulting increased resistance to interference. This is accompanied by a damping of the sound intensity 5. The sound energy returning from the roof panel is greatly reduced
    Since in the Ausfühningsform described the directly attached to the back of the support layer 30 barrier layer 80, the areas 38,40 with the perforation completely spared, resulting in addition a SchalWämpfung in another, higher frequency range. For a higher frequency acoustic radiation whose effective wavelength is approximately four times the distance between the Trägerschichl 30 and the roof plate, the partially air-permeable material of the support layer 30 acts in the same manner as above the overlying cushioning layer. Thus, the presented cladding realized a good sound attenuation in two different frequency ranges. For the typical application in a motor vehicle, the low-frequency absorption will be tuned to the typical photon-induced sound, while the higher-frequency absorption will preferably be designed for tire and wind noise. 20/06/2011 07:51
