Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an interior door trim that is mounted on substantially the entire front side of a vehicle front door, and more particularly to a door trim upper that forms a belt line of the front door. The present invention relates to a door trim structure in which a front side has a shape that is bent obliquely upward and a warp portion of the door trim upper is reinforced by a phosphorus hose.

(Prior Art) As shown in FIGS. 4 and 5, an example of a front door 12 of an automobile 10 such as a passenger car is generally composed of a door outer panel 5 and a door inner panel 3 made of sheet metal. The front and rear mating portions of the door 5 and the door inner panel 3 and the mating portion on the lower end side are joined by riveting, welding or the like.

The belt line (waist line) side of the door outer panel 5 and the door inner panel 3 is open for opening and closing the door glass 9, and the belt line is provided on the upper end edge side of the door inner panel 3 to reinforce the opening portion. A belt line link hose 4 for reinforcing the portion is provided.

Further, from the substantially entire surface of the door inner panel 3 on the vehicle interior side to the belt line link hose 4, interior, sound insulation,
A door trim 1 is attached for sound absorption. The door trim 1 is usually made of a skin material 1a made of vinyl chloride, leather, cloth, etc. and a pad material 1b made of urethane foam, vinyl foam, etc. It is integrally molded.

Here, when the door trim upper 1c forming the upper portion of the door trim 1 is integrally formed, it is usually formed in a structure in which the cross-sectional shape is inverted U-shaped along the belt line link hose 4 as shown in the drawing, and the front door vehicle is formed. A belt line on the indoor side is formed, and a weather strip 7a for the door glass 9 is attached to the folded portion of the door trim upper 1c, and a gap between the folded portion of the door trim upper 1c and the door glass 9 is formed. It is sealed.

Further, the door outer panel 5 facing the weather strip 7a attached to the folded portion of the door trim upper 1c.
Door molding 6 usually made of stainless steel etc. on the side
Is attached to the door molding 6. A weather strip 7b for sealing the outside of the door window is attached to the door molding 6.
Is attached to seal the gap between the door glass 9 and the outer panel 5.

Incidentally, in FIG. 4 and FIG. 5, the above door trim upper is shown.
In the case of integral molding, the folded back length of the folded back portion 1e of 1c cannot be too long due to restrictions at the time of die cutting. Further, the upper surface of the door trim upper 1c forming the belt line of the front door 12 and the upper surface of the door molding 6 are usually formed in a straight line shape in order to ensure the sealability by the weather strips 7a and 7b and the design. Further, the height h of the upper surface of the door trim upper 1c and the upper surface of the door molding 6 are substantially the same, and there is almost no step between them.

By the way, when the belt line of the front door 12 is formed in a straight line, a step is usually generated between the front end of the door trim upper 1c and the side portion of the instrument panel due to the difference in the mounting height, and thus the instrument panel. There is a problem in that it does not have a continuous feeling with the upper surface (belt line) of the door trim upper 1c and it does not look good.

Also, when forming the outlet for the side defroster on the door trim upper 1c, an opening is provided on the front side of the door trim upper 1c, and the garnish for the defroster is mounted,
If the upper surface of the door trim upper 1c, that is, the belt line is linear, there is also a problem in that the air is not effectively blown out onto the entire surface of the door glass.

Therefore, in order to allow the wind from the side defroster garnish to effectively act on the entire surface of the door glass and to obtain a sense of continuity between the instrument panel and the door trim, as shown in FIG. Front end
1d has a structure in which it is bent obliquely upward so as to match the height of the instrument panel, and the side defroster garnish 8 is attached to the above-mentioned warped portion 1b of the door trim upper 1c,
A door trim structure is known in which the blowing direction is diagonally rearward.

(Problems to be solved by the invention) By the way, when the door trim 1 in which the front side of the door trim upper 1c is bent obliquely upward is formed by integral molding, the length of the folded-back portion 1e of the door trim upper 1c is the same as when the die is removed. Since it cannot be made too long due to the restriction of No. 2, the line of the edge of the folded-back portion also has a shape warped upward at the position of the warped portion.

Therefore, the folded-back portion does not reach the position of the weather strip 7a, and the weather strip 7a attached to the folded-back portion 1e of the door trim upper 1c and the molding 6 on the outer panel 5 side are attached to the door trim upper 1a as shown in A of FIG. The weather strips 7a and 7b must be shaped so as to be bent obliquely upward in accordance with the warp portion 1b.
Alternatively, the molding 6 needs to be remolded anew, resulting in an increase in manufacturing cost. In addition, if the front end side of the molding 6 is warped, the design of the outer appearance may be lost and the appearance may be deteriorated.

Further, the upper edge of the belt line link hose 4 is formed in a straight line shape. Therefore, when the front side of the door trim upper 1c is bent, the warp part 1d and the belt line link hose 4 at that position are separated. Since the relative distance increases, the warp portion 1b of the door trim upper 1d cannot be supported by the belt line hose 4, the warp portion of the door trim upper 1c floats, and the strength of the portion also decreases. In particular, when the side defroster garnish is mounted, since the opening is provided at the position of the warped portion 1d of the door trim upper 1c, the problem that the strength is further reduced occurs.

The present invention has been made in view of the above circumstances, and even when the front end side of the door trim upper of the door trim is formed in a shape that is bent obliquely upward, the strength of the warped portion does not decrease, Moreover, it is an object of the present invention to provide a door trim structure that can use straight door moldings and weather strips and can easily and reliably attach a garnish for a side defroster.

(Means for Solving the Problems) In order to achieve the above object, according to the present invention, an integrally molded door trim is mounted on substantially the entire inner surface of a front door of a door inner panel, and an upper portion of the door trim is formed. The door trim upper is supported by the belt line reinforcement of the door inner panel, and the front side of the door trim upper has a structure in which the front side is bent obliquely upward, and a side defroster is formed in the opening formed in the warped portion of the door trim upper. In a door trim structure with a garnish attached for use between the back side of the warp portion of the door trim upper and the belt line reinforcement, while supporting the warp portion of the door trim upper supported by the belt line reinforcement. It is characterized in that a sheet metal reinforcement for fixing the garnish is provided.

(Operation) According to the present invention, between the back side of the warp portion of the door trim upper and the belt line reinforcement, the warp portion of the door trim upper is supported by the belt line reinforcement and the garnish for the side defroster is supported. By providing the sheet metal reinforcement for fixing, the strength of the warp portion of the door trim upper is increased, the garnish is easily attached, and the fixing is also reliable.

Further, by providing the above-mentioned reinforcement, it is possible to supplement a portion of the door trim that cannot be integrally formed by setting the shape of the reinforcement, and it becomes easy to attach a weather strip or the like.

Here, in the case of integral molding, the door trim upper 1c forming the upper surface portion of the door trim 1 is usually formed in a structure in which the cross section is inverted U-shape along the belt line link hose 4 as shown in the drawing. Forms a belt line on the vehicle interior side.

Further, the front side of the door trim upper 1c is formed in a structure that is bent obliquely upward in order to give a sense of continuity with the instrument panel, and an opening is formed in the warp part 1d of the door trim upper 1c. A garnish 8 for forming an outlet of the side defroster is attached to the opening. 1 and 2 show the door trim upper.
The cross section of the warped portion 1d of 1c is shown.

The cross-sectional structure of the portion other than the warped portion is substantially the same as the general structure shown in FIG.

Here, in the present invention, between the back surface side of the warp portion of the door trim upper 1c and the flange portion 4a formed at the upper edge of the belt line reinforcement 4 is supported by the flange portion 4a of the belt line reinforcement 4. Is provided with a sheet metal reinforcement 2 for supporting the warped portion of the door trim upper 1c and used for fixing the garnish 8 to increase the strength of the warped portion of the door trim upper 1c and to secure the fixing of the garnish 8. To

FIG. 3 shows an example of the shape of the sheet metal reinforce 2. In the illustrated reinforce 2, the outer shape is formed in a saddle shape, and the upper surface 2e is slanted along the warp of the door trim upper 1c. Is inclined to. Further, a concave step portion 2b is formed in the central portion of the upper surface, and the rear surface side of the concave step portion 2b is on the upper surface of the flange portion 4a of the belt line reinforcement 4 as shown in FIGS. 1 and 2. The door trim upper 1c is brought into contact with the upper and lower parts of the door trim upper 1c. Further, a rectangular opening 2c is formed in the upper surfaces 2b, 2e of the reinforcement 2 including the concave step portion 2d, and the lower end side of the garnish 8 is fitted into the opening 2c. A step portion and a plurality of claw-shaped projections 8b are provided on the outer peripheral surface of the garnish 8 that abuts against the opening edge of the opening 2c, and the claw-shaped projections 8b engage with the opening peripheral edge of the reinforcement 2. Then, the garnish 8 is hooked and fixed to the reinforcement 2.

The side walls 2d and 2f extending downward from both side edges of the upper surfaces 2b and 2e of the reinforcement 2 are, as shown in FIG.
Joined with the back side of the warp portion of the door trim upper 1c, the warp portion of the door trim upper 1c is supported and reinforced, and
A step portion is formed on the lower side of the side wall portion 2f located on the door glass 9 side, the step portion being in contact with the edge of the folded-back portion 1e of the door trim upper 1c, and the flange portion 2a extends downward from the step portion.

That is, as shown in FIGS. 1 and 2, when the door trim upper 1c has a structure in which the front side is bent obliquely upward, the door trim upper at the position of the warp
The length of the folded portion 1e of the 1c on the side of the door glass 9 cannot be made long due to the restriction at the time of die cutting. Therefore, the length of this portion is insufficient at the warped portion of the door trim upper 1c, and the weather strip is attached to the folded portion 1e of the door trim upper 1c. Cannot be installed.

For this reason, in the case of the conventional door trim structure, the weather strip side had to be formed into a warped shape in accordance with the warp of the door trim upper. However, in the present invention, the flange portion 2a of the reinforcement 2 has the door trim upper 1c. In order to make up for the lacking portion, the weather strip 7a can be attached to the flange portion 7a of the reinforcement 2 while being linearly formed.

Therefore, in the present invention, it is possible to directly use the straight strip that is usually used as the weather strip. Therefore, the shape of the molding 6 on the door-out panel 5 side can be used as it is, and therefore the line of the molding 6 can be linearly formed as shown in FIG. Will not hurt.
