Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention has excellent assembly workability.
In addition, the present invention relates to a door trim for an automobile, which can significantly reduce weight and cost.

[0002]

2. Description of the Related Art In a vehicle door trim having a weatherstrip for a window glass seal mounted on a garnish portion of a door trim body, an attachment structure for fixing and integrating the weatherstrip to the door trim body is shown in FIG. A base member 31 having an L-shaped cross section is attached to the garnish portion of 30, and a weather glass strip 33 for windshield sealing, in which a core metal 32 is embedded, is attached to the base metal 32.
It is widely known that it is attached with the cut-and-raised claws 32a. Further, as disclosed in Japanese Utility Model Laid-Open No. 6-18030, there is proposed a boss provided on the lower surface side of the garnish portion, which is engaged and fixed to both the inner panel and the weather strip.

However, in any such mounting structure, the base member 31 for mounting is indispensable in any case, so that there is a problem that the number of parts is increased and the weight is increased, and the core is It is necessary to process the cut-and-raised claws 32a on the gold 32, which is troublesome, and further, because the base member 31 is attached to the door trim body 30 in advance, the cutting process of the skin material at the terminal part is There was also the problem that it was difficult to reduce the yield.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and easily and reliably fixes and integrates a door trim body and a weather strip without using a conventional base member. In addition, the number of parts can be reduced, the weight can be reduced, and the processing cost can be reduced. Furthermore, the caulking work can be performed after the skin material is wrapped around the base material, and the freedom of mounting work can be expanded. The present invention has been completed with the object of providing a door trim for an automobile, which is capable of significantly improving the yield of the skin material.

[0005]

SUMMARY OF THE INVENTION An automobile door trim of the present invention made to solve the above-mentioned problems is a vehicle door trim in which a weather glass strip for a window glass seal is attached to a garnish portion of a door trim body. However, the lip portion made of soft synthetic resin is integrated with the main body made of hard synthetic resin in which the connecting boss is formed on the lower surface of the collar-shaped fixing plate. The connecting boss is attached to the door trim main body in a state of being engaged and fixed to an attaching hole provided in the garnish portion.

[0006]

With this structure, the weather strip is composed of a main body made of hard synthetic resin and a lip portion made of soft synthetic resin, and a weather strip is provided on the upper edge of the main body. Since the connecting boss on the lower surface is engaged and fixed in the mounting hole provided in the garnish part, the weather strip can be firmly fixed and integrated in the door trim body at an accurate position without using a conventional base member. In addition, the glass strip also exhibits a sufficient weather strip function. Furthermore, the attachment work of both can be performed very easily and accurately.

[0007]

The present invention will now be described in detail with reference to the illustrated embodiments. In the figure, 1 is a door trim main body, 2 is a weather strip for a window glass seal attached to the garnish portion of the door trim main body 1, and the door trim main body 1 is a fabric in which a urethane foam layer is formed on the back surface of the base material. It is attached with a skin material such as, and the above configuration is basically the same as the conventional one.

In the present invention, the weather strip 2 is formed by injection molding a body portion 21 made of a hard synthetic resin such as vinyl chloride and a lip portion 22 made of a soft synthetic resin like vinyl chloride. It is assumed that they are integrally formed by extrusion molding or the like.
A brim-shaped fixing plate 23 is provided on the upper edge of the main body 21, and connecting bosses 24 are provided at several places on the lower surface of the fixing plate 23. On the other hand, the garnish portion of the door trim body 1 is provided with a mounting hole 5,
The present invention is characterized in that the weather strip 2 is attached to the door trim body 1 by inserting the connecting boss 24 into the attachment hole 5 and engaging and fixing the boss 24 by an arbitrary means.

That is, in the present invention, instead of burying the core metal inside the weather strip as in the conventional case, the main body portion 21 of the weather strip is made of a hard synthetic resin having sufficient mechanical strength. The weather strip 2 is attached to the door trim main body 1 by engaging and fixing the connecting boss 24 provided on the lower surface of the collar-shaped fixing plate 23 at the upper edge of the main body portion to the attachment hole 5 formed in the garnish portion. With this structure, an extremely simple mounting structure is obtained without using a special base member. Of course, the main body portion 21 and the lip portion 22 may be separately molded and then bonded and integrated in a later step.

As means for fixing and fixing the boss 24 inserted into the mounting hole 5 at the tip of the garnish, heat staking is used as shown in the embodiment, and a nut spring 6 is used as shown in FIG. Any fixing means can be adopted depending on design conditions, such as fixing with screws 7 as shown in FIG. 4 or fixing with clips 8 as shown in FIG.

The door trim having such a structure is similar to the conventional one in that the weather strip 2 is attached to the garnish portion of the door trim body 1 to seal the glass window 10, but in the present invention, the weather strip 2 is used. A main body portion 21 made of a hard synthetic resin and a lip portion 22 made of a soft synthetic resin, and is provided on the lower surface of the collar-shaped fixing plate 23 at the upper edge of the main body portion 21 made of the hard synthetic resin. The weather strip 2 has a structure in which the weather strip 2 is attached to the door trim body 1 by engaging and fixing the boss 24 in the attachment hole 5 formed in the garnish portion, and the weather strip 2 can be attached to the door trim without using a conventional base member or core metal. It can be firmly fixed and integrated with the main body 1, and the lip portion 2 made of soft synthetic resin
By 2, the function as a weather strip can be fully exhibited. In addition, such weather strip 2 is mounted by inserting a boss 24 provided on the lower surface of the collar-shaped fixing plate 23 into the mounting hole 5 of the garnish portion to perform heat caulking, or a retaining member such as a nut spring 6 or the like. It can be integrated easily and surely simply by stopping, and it is extremely simple and can be done in a short time without the need for complicated positioning work, etc. In the present invention, the attaching work of the weather strip 2 is performed on the garnish portion which is simply cut and the base material which is wound with the skin material, while the terminal portion is difficult to cut and the yield is poor. Since it is only carried out, the difficult cutting work etc. is not necessary at all, and the processing yield etc. of the skin material can be greatly improved.

[0012]

As is apparent from the above description, according to the present invention, the door trim main body and the weather strip can be easily and surely fixedly integrated without using the conventional base member, and the parts The number of points can be reduced, the weight can be reduced, and the processing cost can be reduced. Furthermore, the caulking work can be performed after the skin material is wrapped around the base material, and the degree of freedom of the mounting work can be expanded, and the skin material can be expanded. The yield can be remarkably improved. Therefore, the present invention has an extremely great contribution to the development of industry as an automobile door trim that eliminates the conventional problems.
