Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for attaching automobile interior parts such as floor carpets, pillar garnishes, and ceiling interior materials to the body of an automobile.

[Conventional technology]

Conventionally, these attachments have been carried out using clips, hook-and-loop fasteners (for example, magic tape: a registered trademark of Velcro), and the like. In particular, hook-and-loop fasteners have been widely used because they require no force to attach and can be attached even if they are slightly out of position.

However, since the back side of conventional hook and loop fasteners is made of polyamide fabric, if the back side of the interior item is made of a polyethylene backing layer, such as a floor carpet, it is not compatible with the polyamide fabric, and the surface It was very difficult to attach the Fuasuna to the interior parts. For example, when welding by heat, polyamide and polyethylene resin have poor compatibility and easily peel off. Furthermore, there are few adhesives that can adhere to both polyethylene and polyamide, and they are difficult to use.

In addition, an adhesive is applied to the back side of the tape-shaped base fabric in advance, and the upper and lower surfaces of the adhesive layer are covered with a film to prevent drying by volatilization so that its adhesive strength does not deteriorate during storage. A magic fastener (Japanese Utility Model Application Publication No. 36906/1983) has been disclosed in which the adhesive layer is laminated in layers and a protective film on the surface of the adhesive layer is peeled off and adhered. Even when this fastener was used, it peeled off due to poor compatibility between the polyethylene resin and the adhesive.

Therefore, the generally used structure was to fix the inner parts to the interior parts with tassels 3, 3', as shown in FIG.

[The problem that the idea aims to solve]

However, fixing by tatsukar 3, 3',
Although sufficient mounting strength can be obtained, Tatsukar 3,
3' stood out on the carpet surface, making it unsightly.

The present invention overcomes the above problems, allows the surface fastener and interior parts to maintain good performance, and is easy to secure.
The purpose of the present invention is to provide a mounting structure for automobile interior parts that does not spoil the appearance.

[Means for Solving the Problems] The means of the present invention for solving the problems is that in a mounting structure for automobile interior parts in which the interior parts are attached to the body of a car using a pair of male and female hook-and-loop fasteners, one The back side of the hook-and-loop fastener is laminated with woven fabric, non-woven fabric, etc. to make it fluffy, and the hook-and-loop fastener is fixed to the back side of the interior component by means such as welding or adhesive bonding, and is attached to the body side in advance. It was attached to the other side.

[Effect]

By fluffing the nonwoven fabric or woven fabric laminated on the back side of one of the pair of surface fasteners, the adhesive permeates and is well fixed to the back side of the interior product due to the anchor effect.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 is a cross-sectional view of the surface fastener of the present invention, and FIG. 2 is a cross-sectional view of the mounting structure of the present invention. Here, 1 is one side of the surface fastener, 2 is the floor carpet, and 4 is the nonwoven fabric. Non-woven fabric 4
The backing layer 2b on the back surface of the floor carpet 2 is fixed by heat welding. However, it may also be fixed using a hot melt adhesive. In this case, all you need to consider is whether or not it can be bonded to the polyethylene side. This is because the side of the surface fastener 1 is fluffy, so that the fibers are well fixed by the anchor effect of biting into the polyethylene or hot melt adhesive. On the other hand, the nonwoven fabric 4 and the surface fastener 1
This is easy if a polyamide hot melt adhesive is used. Alternatively, the nonwoven fabric 4 and the surface fastener 1 may be overlapped and needled to cause the fibers of the nonwoven fabric 4 to bite into the surface fastener 1 side.

In this embodiment, the interior material is the floor carpet 2, but it may also be a pillar garnish.
This is usually made of ABS resin, polypropylene resin, etc., and is not compatible with polyamide fibers. In this case as well, adhesiveness can be improved by laminating the nonwoven fabric 4 or woven fabric on the surface fastener 1 side in the same manner as described above. Further, even if the hook and loop fastener is made of other fibers such as polyester fibers instead of polyamide fibers, the adhesiveness can be improved by adopting the same structure.

[Effect of idea]

As mentioned above, by laminating woven fabric or non-woven fabric on the back side of the hook-and-loop fastener as in the present invention, the adhesion between the interior material and the hook-and-loop fastener is greatly improved, eliminating the need for fixing with a tassel as in the past. , it looks better.
