DETAILED DESCRIPTION OF THE INVENTION <<Field of the Invention>> The present invention relates to a mounting structure for a garnish-less type automobile door trim.

≪Prior art and its problems≫ In general, automotive door trims are divided into two types: one is a so-called full trim that covers the entire side surface of the door inner panel, and the other is a so-called full trim that covers the entire side surface of the door inner panel, and one that exposes the waist portion of the door inner panel, that is, the upper overhang. There are two types of so-called half trims, which cover the sides of the trim.

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

However, recently, in order to give the above-mentioned half trim the appearance of a full trim, the upper part of the skin material attached to the garnish dress core material is extended, and this extension piece is attached under tension along the waist part. Then, 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 the conventional half trim, and improved the aesthetic appearance. At the same time, it is possible to reduce the number of parts and man-hours that are disadvantages of full trim (see Utility Model Application No. 114917, 1983).

However, with this type of garnishless type door trim, there is a problem in attaching the insertion end to the waist portion. For this,
An insert board made of a hard vinyl chloride board is integrally welded to the winding end to provide clamping force when winding.

However, especially in the mounting groove part of the door partition window (triangular window of the fitting type), sufficient winding margin cannot be obtained, and the holding of the winding end against this part is difficult when installing the above-mentioned window. Since this is done only by the clamping force between the weather strip and the groove, there is a drawback that once it is inserted, it can easily come off due to external force.

The reason for this is that to prevent wrinkles from forming on the skin material,
Since the skin material is attached to the waist portion under tension, a force in the direction of shrinkage acts on the skin material in the attached state, and the skin material may also contract due to thermal contraction.

As time passes, the force of the weather strip to press the insert board against the inner panel becomes insufficient.

Since the insert board is made of thermoplastic resin, its shape retention is poor.

etc. are possible.

≪Object of the Invention≫ This invention was made in view of the above-mentioned circumstances, and an object of the present invention is to provide a garnish-less type door trim that is attached to a door having a door partition window. To provide a mounting structure for a door trim for an automobile, which securely and firmly fixes the wrapped end of a skin material attached to the part.

<Structure and Effects of the Invention> In order to achieve the above object, the present invention includes a core material attached to a lower side surface of a door inner panel, a core material laminated on the surface of the core material, and an upper extension end of the core material. It is made up of a skin material that is wrapped along the curved surface of the waist part of the inner panel, an insert board is attached to the wrapped end, and a skin material that is fixed by inserting the insert board inside the waist part. In a garnish-less type automobile door trim that is installed in a door panel having a garnish-less type, the winding end of the skin material that is wound into the mounting groove of the window formed at the lower edge of the partition window is provided with the insert board. A reinforcing steel plate is attached integrally with the window, and the edge of this reinforcing steel plate is bent and a locking pawl is provided along the longitudinal direction, and the weather window is inserted into the mounting groove to hold the window. The strip is characterized in that the locking claws of the reinforcing steel plate bite into the side surfaces of the strip, thereby preventing the wound ends of the skin material from coming off.

According to the above configuration, even in a part where there is no winding margin at the winding end of the skin material, such as the mounting groove of a partition window, the reinforcing board is integrated with the insert board attached to the winding end. By attaching the steel plate, the shape retention of the insert board is improved, and the locking pawl formed on the reinforcing steel plate bites into the side of the weather strip, preventing the wrapped end of the skin material from coming off. This prevents as much as possible the peeling of the skin material due to tension in the pulling direction being applied to the skin material, and the aging of the skin material and weather strip. This has the effect of making it possible to reliably and firmly attach the wound end portion of the skin material in the section.

<<Description of Examples>> Examples of the present invention will be described in detail below with reference to the drawings.
