Definitions

  • the present invention relates to a vehicle trim part with a light guide, which is provided in particular for the interior of a motor vehicle, and to a method for producing the vehicle trim part.
  • Such vehicle trim parts are known from the prior art and are used for interior or exterior lighting of a motor vehicle.
  • Vehicle trim parts according to the prior art have the disadvantage that the light guides in the unlit state are relatively unsightly and / or that their installation is relatively complex.
  • the invention is therefore based on the object to offer a vehicle trim part, which does not have the disadvantages of the prior art.
  • the object is achieved according to the invention with a vehicle trim part with a light guide, which has a groove with which the light guide is positively connected, cohesively and / or clamped.
  • a further preferred or inventive subject of the present invention is a vehicle trim part with a light guide, which has a groove, wherein the groove at least partially receives the light guide.
  • the present invention relates to an equipment part of a vehicle, in particular a vehicle interior trim part, which has a groove.
  • the groove receives the light guide at least partially. It is preferably provided that the light guide can be inserted at least approximately flush into the groove.
  • the light guide is preferably at least partially pressed into the groove and / or inserted into the groove and parallel to it.
  • the width of the visible opening of the groove is smaller than the largest width of the light guide. This results in a positive and / or frictional connection between the
  • the groove is provided with an undercut, for example a recess
  • the light guide has a projection and / or a slope, wherein the projection and / or the bevel engages in the undercut.
  • the light guide may then be provided, for example, trapezoidal or substantially oval or substantially circular.
  • the shape of the cross section of the light guide substantially corresponds to the shape of the cross section of the groove.
  • the size of the cross section of the light guide is equal to or slightly larger or slightly smaller than the cross section of the groove.
  • the cross section of the light guide and / or the groove is provided substantially T-shaped or substantially circular or substantially oval.
  • the vehicle trim part on a decorative skin in which the groove is incorporated.
  • the opening of the groove is located on the visible side of the decorative skin.
  • the decorative skin can be grained.
  • the groove can be introduced by original or reshaping or by removal of material in the decorative skin.
  • Preferred methods are spraying, casting, injection molding, in particular RIM, the slush method or deep drawing.
  • the groove has two opposite sides, wherein at least one undercut is provided on at least one of the sides, preferably on both sides.
  • the groove is substantially rectangular or square or omega-shaped and has at least one, preferably both sides (s), which is provided at right angles to the opening, in each case at least one undercut / bevel.
  • the arrangement of the undercuts is preferably mirror-image.
  • the undercuts are arranged opposite one another.
  • Each undercut may extend over the entire length of the groove or be provided only in sections.
  • the decorative skin is foam-backed with a foam, ie the foam is provided on the side opposite the visible side of the decorative skin.
  • the foam between the decorative skin and a carrier layer of the vehicle trim part.
  • the foaming can be used to mold the groove in the decorative skin, that is done simultaneously with this. The foam stabilizes the shape of the groove and thus improves the bond between the decorative skin and the light guide.
  • the light guide is flexible, d. H. he can be bent comparatively easily. As a result, the optical fiber in an accident is not a security risk.
  • the light guide is made as a very long material and then cut to the desired length.
  • the light guide is not a molded part.
  • the light guide may optionally be provided in the groove.
  • the light guide has one or more points at which light is coupled out, so that the light guide acts as a light source.
  • the light guide fills the cross section of the groove preferably almost completely or preferably completely, but is visible with advantage.
  • the light guide may also partially protrude out of the groove.
  • the light guide can thus serve not only the light transmission, but also the, for example, linear, light extraction.
  • the groove is preferably arranged in a decorative skin of the piece of equipment, which may for example consist of a shaped film, a slush skin or a skin made by injection molding (eg RIM).
  • a decorative skin of the piece of equipment which may for example consist of a shaped film, a slush skin or a skin made by injection molding (eg RIM).
  • RIM injection molding
  • Another object of the present invention is a method for producing the vehicle trim part according to the invention, in which a light guide is pressed into the groove and / or inserted.
  • the groove is provided by Ur- and / or reshaping in the decorative skin.
  • the decorative skin is foam-backed with a foam.
  • the decorative skin is heated prior to molding of the groove.
  • the groove is formed during the foaming of the decorative skin in this.
  • the single figure shows an example and schematically an embodiment of the invention.
  • the fitting 1 consists of a thin decorative skin 2, in which a groove 3 is formed.
  • the groove 3 has a substantially U-shaped cross-section with lateral, mirror-inverted arranged undercuts in the form of depressions 4.
  • the decorative skin 2 is the back, d. H. not visible, provided with a foam 5, which upholstered the decorative skin and at the same time stabilizes the groove in shape.
  • the light guide 6 protrudes slightly beyond the decorative skin 2 and is provided along its longitudinal extent for linear delivery of light (arrows 8). However, it is also conceivable that the height of the light guide is smaller than the height of the groove.
