Description

[Detailed Description of the Invention] This invention relates to an improvement in the mounting structure of a garnish-less type door trim.

In general, automotive door trims include what is called a full trim that covers the entire side of the door inner panel, and the waist part of the door inner panel.
That is, there are two types of so-called half trims, which cover the side surfaces of the upper overhanging portion while leaving it exposed.

For this purpose, the full trim is made by pasting a skin material containing a foam layer on the core, which has a curved surface that covers the entire surface of the door inner panel, and the half trim is made by attaching a skin material containing a foam layer to the core, which is curved to cover the entire surface of the door inner panel. It was completed by pasting a skin material on the parts except for.

However, recently, in order to give the above-mentioned half trim an appearance similar to a full trim, the upper part of the skin material attached to the garnish dress core material is extended, and this extended end is attached under tension along the waist part. Subsequently, a type was developed in which the end part was wrapped inside the waist part and fixed.This eliminated the exposure of the waist part, which was a drawback of conventional half trims, and improved the appearance. At the same time, we are trying to reduce the number of parts and man-hours, which are the disadvantages of full trim.
(See No. 166917).

However, with this type of garnish-less type door trim, there is a problem in attaching it to the rolled-up end of the waist part, especially in the mounting groove part of the door partition window (triangular window of the fitting type). In this case, sufficient insertion allowance cannot be obtained, and the winding end is held in this area only by the clamping force between the weather strip for installing the window and the groove. Some drawbacks were pointed out, such as it coming off.

This invention was made in view of the above-mentioned drawbacks, and its purpose is to securely and firmly fix the winding end of the garnish-less type door trim.

In order to achieve the above object, the present invention is characterized in that a hard insertion piece having at least an L-shape in cross section is integrally attached along the longitudinal direction inside the wrapped end of the skin material. Hereinafter, embodiments of this invention will be described in detail with reference to the drawings.

FIG. 1 shows a case where this invention is applied to a door trim for a rear door.

In the figure, door 1 is door outer panel 2.
, a door inner panel 3, a sash 4 surrounding each panel 2, 3 in a frame shape, and an intermediate sash 5. , 3a includes a weather strip 6.
A rear partition window 7 is fitted through the window 7, and a window glass 8, which is raised and lowered by a lifting mechanism (not shown), is arranged on the front side of the window so that its peripheral edge abuts each of the sashes 4 and 5. has been done.

Therefore, a groove is formed in the waist portions 2a, 3a at the elevation position of the window glass 8, and the waist portion 3a of the inner panel 3 is folded inward as shown in FIG. A clip 9 for attachment is attached.

On the other hand, the installation position of the partition window 7 is such that the waist portions 2a and 3a are joined in a groove shape as shown in FIG. 3a, and the weather strip 6 is fitted into this groove 10.

Next, the door trim 11 includes a core material 12 which is attached along the lower edge of the waist portion 3a of the inner panel 3 and is made of a particle board or a polypropylene composite resin board that is trimmed into the panel shape.
A skin material 13 is attached to the side surface of the core material 12 and its peripheral edge is folded back and bonded to the back side of the core material 12, and the skin material 13 is integrated with the extension end of the upper extension side of the core material 12. An extension piece 14 is provided. Although they are shown separately in the figure, they are actually integrated.

The skin material 13 has a foam layer 13a made of polyethylene foam, foamed PVC, or the like on its back surface, and a skin layer 13b, which may be separate or integral, is formed on the surface of the foam layer 13a.

Further, the extension piece 14 is also made up of a foam layer 14a and a skin layer 14b in the same manner as described above, and an insert board 16 made of a hard vinyl chloride board is provided on the back side of the end 15 of the extension piece 14 that is wrapped around the waist portion 3.
are fixed together along the longitudinal direction by high-frequency welding or the like, and by inserting the insert board 16 into the clip 9 as shown in FIG. 2b, the front part of the extension piece 14 is Side winding end 15
a, that is, a portion located in front of the intermediate sash 5, is fixed, and the extension piece 14 is fixed to the side surface of the waist portion 3a in a state that it follows the bulging shape of the waist portion 3a.

Further, the rear winding end 15b of the extension piece 14,
That is, the portion located at the rear of the intermediate sash 5 is fused and cut at the same time as the insert board 16 is welded, corresponding to the width of the insertion allowance for the subsequent 10, and is formed narrower than the insertion allowance of the front winding end 15a. At the same time, as shown in FIG.
An insertion piece 17 made of a metal channel material and having a substantially L-shaped cross section corresponding to the shape of 0a is integrally attached.

A lip piece 6a is integrally formed on the side surface of the weather strip 6, and the weather strip 6 is press-fitted into the groove 10 together with the lip piece 6a.

Therefore, the L-shaped bent end of the insertion piece 17 is inserted between the lip piece 6a and the side wall of the groove 10 while bending it, and in the inserted state, its L-shaped end is bent as shown in FIG. 3b. The bent end of the shape engages and is fixed to the inner shoulder portion 10a of the groove 10 in a key shape.

Therefore, when this engaging portion is removed, it will not fall off unless it is pulled up to the upper portion shown in the arrow direction. In addition, at the beginning of assembly, this fixed part is held by the force of both the friction when it is inserted between the lip piece 6a and the groove 10 and the tension state of the extension piece 14, but as time passes, it becomes longer. When the piece 14 is loosened and its friction is also reduced, in the conventional case the extension piece 14 is easily removed by pulling it, whereas in this embodiment the insertion piece 17 engages in a key shape. As a result, it does not easily come off even with changes over time, and a strong bond can be obtained.

The insertion piece 17 and the extension piece 14 may be fixed together by, for example, adhesive or double-sided adhesive tape.
Alternatively, a claw is formed on the insertion piece 17, and the extension piece 1 is attached to this.
4 may be caulked.

As explained above in the embodiments, in the mounting structure of the automobile door trim according to the invention, in the above-mentioned garnishless type door trim, the upper part of the door outer panel and the door inner panel at the rear of the door panel is A mounting groove is formed along the edge joint into which the weather strip that holds the lower edge of the partition window is fitted, and the outer side wall of the weather strip is fitted between the inner side wall of the mounting groove and the weather strip. The wound end of the material is inserted and clamped, and a hard insertion piece having at least an L-shape in cross section is integrally attached along the longitudinal direction inside the wound end of the skin material to be inserted into this mounting groove. Therefore, if the wrapped end of the skin material including this insertion piece is inserted between the weather strip and the inner side wall of the mounting groove and fixed, the insertion end will have a key shape inside the waist part. A strong and secure fixation can be achieved.

Therefore, as shown in the embodiments, the present invention is extremely effective for attaching a door trim to a door where there is a portion where sufficient rolling allowance cannot be obtained, such as a partition window portion.
