Description

Technical Field

[0001] The present invention relates to a protective cover for a motor vehicle body. Background Art

[0002] Protective covers for motor vehicle bodies are known. The protective covers are mainly used in the interior area of the motor vehicle body. They are also used in the front or rear area of the motor vehicle body.

[0003] A tape designed to be moisture-proof and flame-retardant is known from the published document DE 10 2013 223 504 A1. The tape is based on modified polylactic acid and is used for bundling and fixing cables.

[0004] A tape for wrapping cables is also known from the patent document EP 1 315 781 B1, where the tape is guided helically around the cable. The carrier of the tape consists of a non-woven fabric having an acrylate system on one side, and the acrylate system serves as an adhesive substance and is applied in strip form. For flame retardancy, red phosphorus, an organic phosphorus compound, an inorganic compound or a foaming compound of ammonium polyphosphate, together with a co-agent (such as antimony trioxide), is added to the non-woven fabric or the acrylate system.

[0005] A flexible composite system can be known from the published document WO 2010 / 057478 A2, which consists of a fabric layer, carbon fibers, and a resin that connects the fabric layer and the carbon fibers and keeps the composite system flexible. The composite system obtains an adhesive after curing under the fabric layer. The composite system is used for the inner lining of a motor vehicle body. Summary of the Invention

[0006] The object of the present invention is to provide an improved protective cover for a motor vehicle body.

[0007] According to the present invention, this object is achieved by a protective cover for a motor vehicle body having the features described below. Advantageous designs with convenient and important improvement solutions of the present invention are given in the corresponding following text.

[0008] The protective cover for a motor vehicle body according to the present invention has a substrate, which has a first coating and a second coating. According to the present invention, the substrate is made of a flame-retardant fabric, wherein the first coating is an adhesive layer and the second coating is a metal layer.

[0009] The protective cover according to the present invention is characterized in that it is particularly compatible with paint and corrosion-resistant. Due to the adhesive layer, the protective cover has a high adhesive force and is waterproof.

[0010] In particular, if the flame-retardant fabric is a flame-retardant glass fabric and / or the first coating is an acrylic adhesive layer and / or the second coating is an aluminum coating and preferably if the substrate is particularly directly accommodated between the first coating and the second coating, the protective cover has flame retardancy and a retention force of more than 6 minutes at 1000 °C. In addition, the protective cover can be applied automatically, thus enabling low-cost manufacture of a motor vehicle body.

[0015] 2. The protective cover according to 1 above,

[0016] characterized in that

[0017] the flame-retardant fabric is a flame-retardant glass fabric.

[0018] 3. The protective cover according to 1 or 2 above,

[0019] characterized in that

[0020] the first coating (4) is an acrylic adhesive layer.

[0021] 4. The protective cover according to any one of 1-3 above,

[0022] characterized in that

[0023] the second coating (5) is an aluminum coating.

[0024] 5. The protective cover according to any one of 1-4 above,

[0025] characterized in that

[0026] the substrate (3) is accommodated between the first coating (4) and the second coating (5). Description of the Drawings

[0027] Other advantages, features and details of the present invention are obtained from the following description of the preferred embodiments and with the aid of the drawings. Without departing from the framework of the present invention, the features and combinations of features mentioned above in the description and the features and combinations of features mentioned below in the description of the drawings and / or shown individually in the drawings can be used not only in the given combinations, but also in other combinations or individually. The same reference numerals are assigned to the same or functionally identical elements. For reasons of clarity, these elements may not be marked with their reference numerals in all the drawings, but this does not affect their relevance. In the drawings:

[0030] Figure 3 The protective cover according to the invention for a motor vehicle body in a third embodiment is shown in perspective view, and

[0031] Figure 4 The protective cover according to the invention for a motor vehicle body in a fourth embodiment is shown in perspective view. Detailed Description

[0032] The protective cover 1 according to the invention for a motor vehicle body 2 is designed according to Figures 1 to 4 design.

[0033] The protective cover 1 (which can also be referred to as a protective pad or a heat protection pad or a sealing cover) serves to cover an opening (not shown in detail) formed in the motor vehicle body 2, wherein preferably a flush arrangement with the body surface (not shown in detail) of the motor vehicle body 2 surrounding the opening is produced. Thus, for example, a fuse box (not shown in detail) arranged in the motor vehicle body 2 can have a baffle to prevent the fuse box from being visible from the interior space of the motor vehicle body 2 with the protective cover 1. However, various arrangements of the protective cover 1 in the motor vehicle body 2 can be envisaged.

[0034] The protective cover 1 is substantially plate-shaped or disc-shaped and is in particular formed with a small thickness 11. The protective cover has a base body 3 formed of a flame-retardant glass fabric. The base body 3 is formed between a first coating 4 and a second coating 5, wherein the first coating 4 is formed in the form of an adhesive layer, preferably an acrylic adhesive layer 4, and the second coating 5 is a metal coating, preferably an aluminum coating. Since the base body 3 is a fabric, the coatings 4, 5 are of course also arranged at least in the edge region 6 of the base body 3.

[0035] In a first embodiment according to Figure 1 and according toFigure 2 In a second embodiment, the protective cover 1 has a circular contour 7, wherein the circular contour 7 of the protective cover 1 according to the first embodiment is interrupted by two nose-shaped portions 8.

[0036] In accordance with Figure 3 a third embodiment and in accordance with Figure 4 a fourth embodiment, the protective cover 1 has a substantially rectangular or square contour 7 with rounded edges 9. Again, the edges 9 can also be implemented as sharp.
