Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates to a door trim for an automobile, and particularly to a mounting structure for a decorative member attached to a door waist portion.

<Prior Art and its Problems> Normally, an interior material called a door trim is attached to the interior side of the door panel of a passenger car.

Recently, various types of interior materials such as door trims with improved design have been proposed. For example, to explain a door trim as an example, parts that require a three-dimensional shape such as armrests use a resin core material to emphasize the three-dimensional effect, and the outer skin material is a combination of cloth, resin sheet, carpet, resin sheet, etc. Types that change the surface texture by using are now mainstream.

In FIG. 3, the door trim 1 includes a trim core body 6 consisting of a board core material 2 having a substantially flat shape, a resin core material 5 integrally forming an armrest portion 3 and a door waist portion 4, It is composed of a skin material 7 having cushioning properties such as polyethylene foam that covers a part of the surface, and a decorative member 8 that is directly attached to the board core material 2 to express a texture different from the skin material 7. ing.
The decorative member 8 is provided in three places on the door trim shown in FIG. It is set in three locations.

The structure of these decorative members 8 will be described by taking the example of a decorative member to be attached to the door waist portion 4. The decorative member 8 is made up of an iron plate core material 8a and a fabric 8b that covers the surface of the iron plate core material 8a and folds the periphery back onto the back surface of the core material 8a. If desired, the core material 8a may be further folded back onto the back surface of the fabric 8b.
To attach the cover 8 to the door trim 1, claws 8c are cut and raised at appropriate positions on the back surface of the core steel plate 8a, and the cover 8 is attached by inserting and fixing the claws 8c into mounting holes 4a in the door waist portion 4.

However, in door trims with this type of structure, a relatively heavy iron plate core material is used as the core material of the decorative member, which increases the weight of the product and causes problems that go against the goal of weight reduction. It was hot.

Furthermore, since the iron plate core material 8a is fitted and fixed to the outer surface of the door waist portion 4, it is necessary to bend it into approximately the same shape as the outer surface of the waist portion 4.
It must be formed accurately; for example, if the iron plate core material 8a is too small, it will not be possible to attach this decorative member to the door waist part, and if it is formed too large, problems such as wobbling may occur after installation. occurs. As described above, precision in shape is required for the iron plate core material that forms the base of the decorative member, and the irregularity of the shape makes installation difficult and causes problems such as wobbling after installation.

[Purpose of the invention] This invention was made in view of the above-mentioned circumstances.The purpose of this invention is to simplify the structure of the decorative member attached to the door trim, especially the door waist part, and to reduce the weight. It is an object of the present invention to provide a door trim for an automobile in which the workability of attaching the decorative member is improved.

《Structure and effects of the invention》 In order to achieve the above object, this invention consists of a three-dimensional armrest part and a door waist part made of a resin core material integrally molded with synthetic resin, and this resin core material is made into a substantially flat shape. A door trim is fixed on a board core material, a decorative member is attached to the door waist portion, and a skin material is coated on a desired part of the surface of the core material, the decorative member being folded into a U-shaped cross section. a pair of curved metal brackets; a wire connecting the pair of brackets at a predetermined interval so as to be positioned on both sides of the door waist portion; both sides of the brackets are attached to the bracket; It is made of a piece of cloth held in a shape that is approximately the same as the external shape of the door waist part, and is characterized in that a claw protruding from the back surface of the bracket is inserted and fixed into a mounting hole on the surface of the waist part.

In other words, regarding the door trim according to the present invention,
The decorative member attached to the door waist part of the door trim consists of a pair of metal brackets placed on both sides of the door waist part, a wire connecting the brackets, and a wire attached to the brackets, and is attached to the upper and lower surfaces of the door waist part. In addition, since it is composed of a fabric that covers the surface, the weight of the metal core material can be significantly reduced compared to those using conventional iron plate core materials, making it possible to reduce the weight of decorative components and, by extension, the weight of door trims. can make a major contribution.

Furthermore, in the mounting structure of the decorative member according to the present invention, metal brackets are fitted and fixed on both sides of the door waist portion, and the shape of the fabric is held by these brackets so as to follow the shape of the door waist portion. Because of this, the fabric easily follows the upper and lower surfaces of the door waist part and the surface other than where the bracket is attached, and compared to the conventional method where it is fitted and fixed to the entire door waist part, it is easier to fit only on both sides of the door waist part. Since only fitting and fixing is required, the number of parts requiring shape accuracy is reduced, which has the effect of maintaining good installation workability and stability after installation.

<<Description of Embodiment>> Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.
