Definitions

  • the present invention relates to a hole-covering damping film for vehicle floors according to the preamble of claim 1.
  • Vehicle floor panels are shaped in a variety of ways to meet a variety of mechanical requirements.
  • these floor panels have stiffening beads or recesses which, among other things, serve to fasten other vehicle parts.
  • Hole beads generally have a hole through which a fastening means, in particular a screw, can be passed.
  • the vehicle floor panels are designed in such a way that they can be used for different types of vehicles. It is therefore understood that not all openings or holes made in the floor panel are used for their intended purpose in the assembled state. There is therefore a need to subsequently seal these openings again.
  • Elements for sealing unused holes in such floor panels are well known to the person skilled in the art and can be designed in the form of sealing plugs made of plastic and / or rubber. These plugs, for example, are attached to the floor panel in a watertight manner using adhesives.
  • Foil-like covers are also known, which are glued over the holes. These foils tend to sag heavily in the hole area. Films are therefore also known: which cover the entire surface with a stiffening layer, e.g. covered from cardboard, paper or aluminum
  • BFS1 ⁇ TIGLJNCSK0PIF are. These stiffened foils, however, are difficult to attach, in particular glue, to the floor panel in the area of beads, in particular perforated beads.
  • Attaching these hole covers requires a separate manufacturing step.
  • selected sealing plugs must be inserted into the differently shaped floor panel openings or differently sized pieces of film must be correctly positioned on the openings, which proves to be time-consuming and labor-intensive.
  • a hole cover is to be created which is suitable for use with hole beads and which does not sag significantly in the hole area in the case of larger openings.
  • a damping film having the features of claim 1, and in particular with a damping film which is partially provided with a reinforcing layer in predetermined areas.
  • the predetermined areas lie over a hole in the floor panel and in particular over a hole bead. This leads to the relatively white damping film being prevented from sagging through the hole by the reinforcing layer, which would lead to an undesired depression on the inside of the vehicle. It goes without saying that this reinforcing layer can be applied on either or on both sides of the damping film.
  • the area to be reinforced lies above a vibration area of the floor panel. It is known to the person skilled in the art that vibrations or.
  • Vibrations of larger flat components form different vibration areas between which so-called node lines run. In the area of the node lines, these flat components vibrate only minimally, while these components generate undesired antinodes in the vibration areas. It is these vibration areas that can be additionally dampened with the present invention without having to increase the mass of the damping film significantly in these areas.
  • this step can be dispensed with, but at the same time the steaming behavior of the steaming film can be locally influenced or controlled in the desired manner.
  • FIG. 1 shows a schematic section of a preferred embodiment of a damping film according to the invention in the assembled state
  • Fig. 2 is a schematic sectional view of a further embodiment of an inventive
  • FIG. 1 shows a base plate 1 m which has a hole bead 2 formed in it and which hole bead a central hole 3 having.
  • a damping film 4 according to the invention is attached to this floor panel.
  • This damping film is provided with an additional reinforcing layer 5 at least in the area ⁇ of the bead 2.
  • This reinforcing layer 5 can consist of paper, cards, plastic, felt, aluminum, etc. and can be designed to be completely flat or lattice-shaped.
  • This reinforcement layer can be laminated on, calendered and / or glued on. It is thereby achieved that the full-area damping film 4 can nestle unhindered along the course of the beads and thus can perform its sound-absorbing function even better.
  • the full-area damping film 4 can nestle unhindered along the course of the beads and thus can perform its sound-absorbing function even better.
  • the full-area damping film 4 can nestle unhindered along the course of the beads and thus can perform its sound-absorbing function even better
  • Reinforcement layer 5 prevents the damping film 4 from sagging in the hole area 3.
  • Reinforcement layers 5a influence and control the damping behavior of the damping film 4 in the desired manner.
  • areas 6a in which vibration antinodes are to be formed in a predictable manner hereinafter referred to as vibration areas, can be specifically damped.
  • the damping film 4 according to the invention thus fulfills several functions simultaneously.
  • damping film 4 according to the invention in the assembled state.
  • This damping film 4 is in turn applied to the entire surface of a floor panel 1 and conforms to the contours thereof, in particular in the area of severe deformations, for example a bead 2.
  • this damping film 4 is provided in the region 6 of the bead 2 with a reinforcing layer 5, which prevents the soft damping film 4 from sagging through the opening 3. It also protects Reinforcement layer 5 the damping film 4 against mechanical injuries in the hole area.
  • Suitable damping foils are well known to the person skilled in the art. In particular, it makes sense to use a damping film known under the name "IFF". It goes without saying that the partial reinforcement layers 5, 5a can be attached to both sides of the damping film 4 and the person skilled in the art can do so depending on the function to be performed Arrange and dimension reinforcement in a suitable manner, / ⁇ rd.
  • damping foil according to the invention allows the person skilled in the art to influence the damping behavior of the damping film in a targeted manner and the mere partial arrangement of the reinforcing layers 5, 5a allows the vehicle floor gaps to be sealed well, in particular water-impermeably, by the damping film without sagging in the area of the perforation 3. It goes without saying that these reinforcing layers 5, 5a can also be arranged in areas in which increased mechanical stress on the damping film can be expected.
