Description

  • The invention relates to a trim part arrangement for a vehicle, in particular for a motor vehicle, according to the preamble of claim 1.
  • A well-known, generic trim part assembly has a first trim part and a second trim part, wherein in the assembled state of both trim parts in a vehicle interior a trim part edge region of the first trim part from the vehicle interior at least partially behind a trim part edge region of the second trim part to form a coverage area is arranged. At least one airbag is disposed behind the cowling subassembly which, when activated in the course of its deployment, exerts a compressive force at least on the first cowling.
  • Specifically, the first trim part is formed by a headliner for a motor vehicle. The headliner has, in addition to a stiffening layer, a fabric layer facing the vehicle interior in the mounted state as a visible side. The fabric layer is laminated to a thin foam material, so that overall the perceived by the vehicle occupants impressions in terms of look and feel are desired in the desired manner. In addition, a further foam layer with appropriate material thickness is provided, which acts in the manner of an energy absorption layer. This means that, for example, an energy absorption occurs in the case of a vehicle rollover due to this foam layer. The stiffening layer extends to the edge regions of the headliner seen in the mounted state of the headliner, so that these edge regions of the headliner extending in the vehicle longitudinal direction have a desired stability in the mounted state. In the field of columns, such as. B. the B-pillar is a pillar trim arranged as a second trim panel in the mounted state relative to the headliner that seen in the vehicle vertical direction upper edge region of the pillar trim partially covers the edge region of the headliner. If, in the event of a collision, an airbag arranged behind the headliner in the region of the roof spar is activated, a compressive force acts from the rear on the edge region of the headliner during the deployment of the airbag, whereby a corresponding airbag outlet opening for the airbag is formed. In the overlap area of the pillar cladding over the headliner, this compressive force therefore also acts on the upper edge region of the pillar trim, so that there is a risk of breakage of the pillar trim. To prevent this, the roof lining in the region of the overlap with the pillar trim pruned jagged, so that thereby a correspondingly "soft" coverage area is formed on the headliner. As a result, the headliner can be pushed out of the covering area during the deployment of the airbag without a possible breakage of the pillar trim.
  • Such a trim part arrangement for accommodating a side airbag in the gutter of a motor vehicle is for example from the US 2003/0146606 A1 known. Furthermore, the shows DE 697 13 246 T2 also a comparable arrangement for a vehicle occupant / protection device.
  • The object of the invention is to improve a generic trim part assembly for a vehicle, in particular for a motor vehicle, with simple and cost-effective production on.
  • The object is achieved with respect to the trim part assembly with the features of claim 1.
  • In accordance with claim 1, the trim part edge region of the first trim part in the overlapping area is designed as a trim part weakening area with a reduced rigidity compared to the adjacent trim area of the first trim part as well as to the trim part edge area of the second trim part lying in the overlap area.
  • The advantage here is that due to the trim part weakening region in the case of a force applied to the first trim part in the direction of the second trim part in the covering area, such as in an airbag shot, in which the unfolding airbag exerts a compressive force on the first trim panel, a possible breakout or Canceling the second trim part, in particular in the trim part edge region of the second trim part, is excluded. The first trim panel is pressed over the trim panel edge portion of the second trim panel with such a load on the "soft" trim panel weakened area. Since the second trim panel with its trim part edge region seen from the vehicle interior is arranged in front of the trim part edge region of the first trim part to form the overlap region and preferably forms an abutment there with the first trim part, the first trim part is despite the reduced stiffness In the paneling weakening area in the assembled state, functionally reliable and stable.
  • According to a further embodiment, the covering part may be constructed from a fabric layer as the visible side of the covering part, the stiffening layer and a foam layer. The fabric layer creates an appealing look and feel for the trim panel. The fabric layer can be easily laminated on the stiffening layer, for example. The foam layer may be designed to have an energy absorption function. As a result, the safety for the vehicle occupants is additionally increased, since an energy absorption occurs in the event of an impact of the vehicle occupant against the trim part due to the foam layer.
  • Furthermore, a stiffening layer can be arranged on each side of the foam layer. As a result, an inherently stable covering part is created as a whole, but due to the foam layer has a desired energy absorption function. In the trim part weakening region, both stiffening layers can then be reduced or completely omitted with respect to the material thickness.
  • In a preferred embodiment, the first trim part may have an at least two-layered construction with at least one stiffening layer. The stiffening layer is in the overlapping area at least partially reduced in terms of material thickness or is completely omitted to form a trim part weakening range. Thus, the trim panel weakening area can be easily and inexpensively manufactured.
  • In a specific embodiment, the stiffening layer may be made of a glass fiber material. Through the use of glass fibers, fewer or no glass fibers can be arranged in the lining part weakening area during the production of the lining part or the stiffening layer of the lining part, so that the covering part weakening area can thereby be formed in a simple manner. In principle, other materials for stiffening the trim part, such as glass fiber mats can be used instead of the glass fibers. The glass fiber mats may have a corresponding trim in the region of the trim part weakening region, so that no glass fiber mat is present when the glass fiber mats are applied to form the stiffening layer in the trim part weakening region.
  • In a further embodiment, the stiffening layer can be formed by a carrier layer to which a glass fiber material is applied as a stiffening material and connected thereto. The carrier layer may be designed so that the desired rigidity is achieved by applying and bonding the glass fiber material to the carrier layer. In principle, the glass fiber material can also be applied directly to a layer present on the lining part, such as, for example, the foam layer, and connected to it in a corresponding manner.
  • According to a further embodiment, the individual layers of the trim part can be firmly connected to each other. Thus, despite the plurality of different layers as a final product in the production of a single component is formed as a trim part. A simple way of connecting the individual layers is, for example, a bond, wherein in principle all other technically possible bonding techniques can be used.
  • In a specific embodiment, the first trim part may be formed by a headliner and the second trim part may be formed by a pillar trim. Thus, a conventional construction of trim parts in a vehicle interior is proposed, in which the pillar trim in the vehicle vertical direction protrudes upward to form the overlap region partially over the edge region of the headliner. In the edge region of the headliner next to the trim part weakening region, the stiffening layer is present continuously, so that there is formed in the desired manner an intrinsic stability of the edge region of the headliner. In the trim part weakening area, in which the stiffening layer is preferably completely absent, so that the rigidity of this edge region of the headliner is reduced, a "support" for this edge region of the headliner is given by the overlapping pillar trim in the mounted state of headliner and pillar trim.
  • Reference to a drawing, an embodiment of the invention is explained in detail.
  • Show it:
  • 1 a schematic plan view of a portion of a headliner,
  • 2 a schematic sectional view through a headliner and a pillar trim as trim part assembly in the assembled state,
  • 3 a schematic sectional view through a trim panel with stiffening layer, and
  • 4 a schematic representation of a manufacturing process of a stiffening layer.
  • In 1 is a schematic plan view of a portion of a headliner 1 shown as a trim part. Each in a lateral edge area of the headliner 1 with a hatched area is a fairing weakening area 2 located. The headliner 1 is multi-layered, wherein in the two trim part weakening areas 2 a stiffening layer 3 is missing. This stiffening layer 3 is in the remaining area of the headliner 1 designed so that overall a dimensionally stable component is created, which in the trim part weakening areas 2 due to the lack of stiffening layer 3 Is formed "soft", ie that there the rigidity of the headliner 1 is reduced.
  • In 2 is a schematic sectional view through a trim part assembly 4 passing through the headliner 1 and a pillar trim 5 is formed. The headliner 1 and the pillar trim 5 are shown in each assembled state, the sectional plane is defined by the vehicle vertical direction and the vehicle transverse direction. The headliner 1 is from a fabric layer 6 , which at the same time the visible side to a vehicle interior 7 forms, the stiffening layer 3 and a foam layer 8th built up. With the fabric layer 6 is given to the vehicle occupants a visually and haptically appealing design of the headliner. The foam layer 8th may be formed in the manner of an energy absorbing element.
  • The pillar trim 5 forms in the vehicle vertical direction seen upper edge region a coverage area 9 with the edge area of the headliner 1 out. How out 2 is apparent in this coverage area 9 the trim part weakening area 2 arranged, ie that here the stiffening layer 3 is omitted. This is the headliner 1 in the overlap area 9 "Soft" trained with a reduced rigidity compared to the subsequent cladding area of the headliner ( 1 ) as well as in the overlapping area ( 9 ) lying trim part edge region of the pillar trim ( 5 ). Behind the trim part assembly 4 is an airbag 18 arranged. In the course of deployment of the airbag 18 becomes a compressive force on the headliner 1 exercised in the overlap area 9 also on the pillar trim 5 is transmitted. Due to the trim part weakening area 2 but is the edge area of the headliner 1 over the edge area of the pillar trim 5 pressed, causing a breakout or cancel the pillar trim 5 is prevented. This is schematic with dashed lines in 2 located.
  • In 3 is a schematic sectional view through a cowling 10 in a further embodiment with a stiffening layer 11 shown. Such a trim part 10 For example, as related to the 1 and 2 be described, formed by a headliner. The fairing part 10 has a fabric layer 12 on, to which a carrier layer 13 borders. On the carrier layer 13 are glass fibers 14 arranged so that the glass fibers 14 together with the carrier layer 13 the stiffening layer 11 form. To the glass fibers 14 closes a foam layer 15 on, where on this another stiffening layer 11 made of glass fibers 14 and carrier layer 13 exists, is arranged. The individual layers 11 . 12 . 13 and 15 can be firmly connected to each other with an adhesive, so that a total of a one-piece trim part 10 is trained.
  • How out 4 become apparent in the production of the stiffening layer 11 the glass fibers 14 , for example via a corresponding conveyor belt 16 on the carrier layer 13 applied, while at the same time an adhesive can be applied, so that the glass fibers 14 firmly on the carrier layer 13 are connected. The carrier layer 13 is doing in the arrow direction of the arrow 17 relative to the conveyor belt 16 moved, so that allows the glass fibers 14 on the total surface of the carrier layer 13 are arranged. To form a trim part weakening area, the carrier layer 13 Covered with a corresponding cover (not shown here), so that there are no glass fibers on the carrier layer 13 can be attached. After attaching the glass fibers 14 on the carrier layer 13 the covers are simply removed, so that the trim part weakening areas are formed free of glass fibers.
