Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates to a door trim in which a door trim body and a garnish are formed separately, and in particular to an improvement in the joint structure thereof.

<<Prior art and its problems>> Automobile door trims are broadly classified into half-trim type and full-trim type.

A half-trim type door trim is attached only along the lower side of the waist of the door inner panel, and a full-trim type is attached to the door trim with a garnish that is approximately U-shaped in cross section to completely cover the waist part. It is integrated on the main body.

This type of full trim generally has a garnish core material made of a press-formed material such as a substantially U-shaped steel plate fixed to the upper edge of the core material constituting the door trim body using metal stitchers, etc., to form a core part. Generally, a skin material is bonded to the entire surface via a pad material or the like.

However, in the case of a structure in which the whole is integrated in this way, first of all, in terms of appearance, the outward protrusion of the garnish part is small, and the desired design appearance cannot be obtained. There is a lack of flexibility, such as the ability to use different colors for the door trim and the door trim body, or to arbitrarily choose between a half trim and a full trim.

In response to this, some door trims are divided into two parts, a door trim body and a garnish, and the two parts are attached to the door inner panel.

However, these two parts are attached using metal stitchers or separate clips, but these methods are difficult to work with or require separate parts such as other clips. Some drawbacks have been pointed out, such as poor adhesion strength after installation, and lack of flexibility in assembly line operations.

<<Purpose of the invention>> The object of this invention is to simplify the assembly of the two-part door trim as described above, and to increase the joint strength between the two parts.

<Configuration and Effects of the Invention> In order to achieve the above-mentioned object, the present invention provides a door trim in which a door trim body and a garnish are separated, and the garnish is provided with a tip thereof facing inward at an appropriate interval. a plurality of L-shaped elastic locking pieces that are biased, and a plurality of locking holes that engage with the locking pieces are formed in the upper edge of the door trim body; the door trim body of the garnish; When attaching to the garnish, by pressing the garnish with the upper edge of the door trim main body sandwiched between the inside of the garnish and the locking piece, the locking piece is elastically distorted and its tip is inserted into the locking hole. Further, in the inserted state, the locking piece elastically returns to prevent the locking piece from coming off.

According to the above configuration, when attaching the garnish to the upper edge of the door trim body as necessary, the garnish can be fitted and attached with one touch without the need for conventional attachment means such as metal stitchers or clips. The bonding strength is extremely high in this condition, making it easy to apply it to an inner panel as a half trim or as a full trim, depending on the order, on an assembly line for passenger car interior materials, for example. If you prepare several types with different color combinations, you can freely choose a combination.

<<Description of Embodiments>> FIGS. 1 and 2 show a two-part type automobile door trim according to this invention.

In the figure, the door trim includes a door trim body 1 attached to the side of the inner panel of the automobile;
It is composed of two parts: a garnish 2 that covers the waist part.

The door trim body 1 consists of a board core material 3 trim-cut along the surface shape of the inner panel, and a skin material 5 attached to one side surface of the core material 3 via a pad material 4, and The surface of the skin material 5 has the required linear groove pattern 6,
6... are formed, and the peripheral edge of the skin material 5 is rolled up and bonded to the back side of the core material 3.

The garnish 2 also includes a garnish core material 7 formed of a plastic injection molded body having a substantially U-shaped cross section, and an elastic material such as a foamed vinyl chloride sheet attached to the surface of one side of the garnish core material 7. It is composed of a skin material 8 having a.

And, on the inner surface of the garnish core material 7,
Elastic locking pieces 9, 9 that are L-shaped downwards...
are integrally molded, and a locking claw portion 9a is formed at each tip. This locking pawl 9a is located in an eccentric state toward the garnish core material 7 side.

Correspondingly, on the upper edge of the core plate 3 of the door trim body 1, corresponding to each of the elastic locking pieces,
A plurality of locking holes 3a, 3a, . . . are formed in a line at appropriate intervals.

Therefore, in the automobile door trim configured in two parts as described above, the garnish 2
To attach the elastic locking piece 9 to the door trim body 1, the upper edge of the door trim body is inserted between the elastic locking piece 9 and the inside of the garnish core 7, and the elastic locking piece 9 is inserted. The locking pawl 9a is elastically distorted, and if the garnish 2 is pressed from above in this state, the locking pawl 9a elastically enters the locking hole 3a, and in this state, the locking piece 9 elastically returns. By doing so, it is prevented from coming out from the locking hole 3a, thereby completing the connection between the two as shown in FIG.

Therefore, in order to integrally assemble the door trim according to this invention to the vehicle body side on an automobile production line, first the door trim body 1 is attached to the side surface of the inner panel, and then the garnish 2 is attached.
The installation is completed by fitting it onto the upper edge.

Conversely, it is also possible to attach the garnish to the door trim body 1 on the vehicle body side.

Claims (1)

[Claims for Utility Model Registration] In a door trim in which a door trim body and a garnish are separated, the garnish has a plurality of L-shaped elastic bars at appropriate intervals with their tips deviated inward. A plurality of locking holes are formed in the upper edge of the door trim body to engage with the locking pieces; when the garnish is attached to the door trim body, the garnish is engaged with the inside of the garnish. By pressing the garnish with the upper edge of the door trim body sandwiched between the locking pieces, the locking piece is elastically distorted and its tip is inserted into the locking hole, and in the inserted state, the locking piece elastically returns to its original state. An automobile door trim characterized in that the door trim is prevented from being removed.
