Description

[Detailed Description of the Invention] << Industrial Application Field >> The present invention relates to an automobile door trim, and in particular, an armrest pad installed in an armrest part is made to also serve as a spacer between the door trim and the door inner panel. The present invention relates to an automobile door trim with a shortened manufacturing process.

<< Prior Art >> Usually, as shown in FIG. 6, an automobile door trim 2 installed in a door inner panel 1 includes a molded core material 3 formed in a curved shape so as to obtain a desired product appearance, and It is generally composed of a skin material 4 attached to the surface of the molded core material 3 and imparting decorativeness.

The molded core material 3 has sufficient rigidity in consideration of shape retention and attachment to the door inner panel 1.
In addition to the decorativeness of the product surface, the skin material 4 is lined with a foamed layer if desired to give a soft feeling.

Further, the molded core material 3 is formed so that its substantially central portion is bulged toward the vehicle interior side to form an armrest portion 5, and an armrest pad 6 for thickening formed by molding is attached to the armrest portion 5, and this cushion is formed. The effect is to make passengers comfortable.

By the way, a spacer 7 made of a cushion material such as urethane foam is provided between the door inner panel 1 and the door trim 2.
Even if the door trim 2 is pressed to the inner panel 1 side, the door trim 2 is not easily deformed, and an unpleasant sound due to vibration during traveling is prevented from being generated. .

<< Problems to be Solved by the Invention >> However, in such a conventional door trim for an automobile, a spacer 7 formed separately is formed into a formed core material 3.
Since it is attached to the back side of the door trim 2, the number of man-hours for manufacturing the door trim 2 is increased, which causes a cost increase, and the spacer 7 is a cut product of polyurethane foam. It is also pointed out that the shape cannot be effectively dealt with and the effective spacer function cannot be exhibited.

The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the number of cushion materials that function as spacers between the door inner panel and the door trim and to attach the cushion material separately to the door trim side. By reducing the number of man-hours required, the total manufacturing process of the door trim is shortened, and by providing a spacer that effectively corresponds to the shape of the door inner panel, we provide a vehicle door trim that guarantees a reliable installation. To do.

<Means for Solving the Problem> In order to achieve the above object, the present invention is to fix an armrest pad formed by molding on the surface of an armrest portion located substantially in the center of the core material, and to fix the core material and the armrest pad. In an automobile door trim having a front surface covered with a skin material, a protrusion is formed on the back side of the armrest pad, and an opening corresponding to the protrusion is formed in the core material, and the protrusion is opened. It is characterized in that the projection is configured as a spacer between the door trim and the door inner panel by projecting the core material through the through to the back surface side and abutting the tip end portion thereof against the door inner panel surface.

<Operation> With the above configuration, in the automobile door trim according to the present invention, the protrusion is provided on the back side of the armrest pad, and the protrusion is projected to the back side of the core material through the opening of the core material. Since the spacer function is provided between the inner panel and the inner panel, the cushion material as a spacer, which has been separately attached to the rear side of the armrest of the door trim, is not required.

Further, since the armrest pad is molded into a predetermined shape, it can sufficiently cope with the complicated surface shape of the door inner panel and an appropriate spacer function can be obtained.

<< Embodiment >> Hereinafter, each embodiment of the vehicle door trim according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 show a first embodiment of the present invention. FIG. 1 is a front view of a door trim, and FIG. 2 is a sectional view of the same vehicle door trim. FIGS. 3 to 5 show a second embodiment of the present invention. FIG. 3 is a front view of an automobile door trim, FIG. 4 is a sectional view of the door trim, and FIG. 5 is an armrest pad. It is an expanded sectional view shown.

First, a first embodiment of a vehicle door trim according to the present invention will be described with reference to FIGS.

In the drawing, a vehicle door trim 10 is an armrest.
11 and the door waist portion 12 are each bulged toward the vehicle interior side, and a molding core material 13 molded to have a desired curved shape, an armrest pad 14 adhesively fixed to the upper surface 11a of the armrest 11, and the above-mentioned molding It is composed of a core material 13 and a skin material 15 that covers the outer surfaces of the armrest pad 14.

More specifically, the molding core material 13 is obtained by mixing and stirring a mixture of a polyolefin resin and wood powder at an appropriate mixing ratio, and then extruding it into a sheet by a T-die extrusion molding machine.
After heating and softening this sheet, it is formed by press forming in a cold press forming die having a desired curved surface shape, and the armrest pad 14 is used when the occupant applies a load by applying an elbow. In addition, a polyurethane foam having a modulus of elasticity that gives a cushioning property without a feeling of bottoming is formed into a required shape in a mold for molding (not shown) using a material.

On the other hand, the skin material 15 is integrated by vacuum molding or the like so as to cover the outer surfaces of the molding core material 13 and the armrest pad 14, but in consideration of cost and moldability, ABS resin mixed P
A VC sheet is preferable, and if desired, a soft feeling can be given to the entire surface of the door trim 10 by lining a foam layer such as polypropylene foam or polyethylene foam on the back side.

The structure of the automobile door trim 10 according to the present invention is characterized in that the armrest pad 14 has a protrusion 16 formed on the back side thereof, and the protrusion 16 is formed at two positions in this example. Two openings 17 are formed in the material 13, through which the projections 16 are projected to the back side of the molding core material 13, and the door inner panel 18 is brought into contact with the tip portion 16a of the projections 16 and the armrest. The shape of the pad 14 is set.

In this way, the protrusion 16 integrally formed on the back surface side of the armrest pad 14 imparts a spacer function between the door trim 10 and the door inner panel 18, and the protrusion 16
The tip portion 16a of the spacer is in contact with the door inner panel 18, and the protruding portion 16 is a spacer bonded to another portion.
It has the same function as 19 and therefore the car door trim
Even if 10 is pressed toward the door inner panel 18, the door trim 10 is not likely to be deformed, and rattling noise is not generated due to vibration or the like during traveling.

Therefore, compared to the conventional cushion material used as a spacer that is attached to the door trim side, the cushion material on the back side of the armrest is not required and the attaching process can be omitted, resulting in material saving and process shortening. Cost reduction can be expected.

Further, since the armrest pad 14 is formed by molding, the shape of the protrusion 16 can be arbitrarily set, so that the armrest pad 14 can follow the complicated surface shape of the door inner panel 18 and thus is superior to the conventional urethane cut product. A buffering effect can be expected.

Furthermore, when positioning and fixing the armrest pad 14 to the molded core material 13 side, if the protrusion 16 of the armrest pad 14 is passed through the opening 17, the armrest pad 14 can be easily and quickly attached to the molded core material 13. Even if external pressure is applied to the armrest pad 14 in the step of covering and adhering the outer surface of the molding core material 13 and the armrest pad 14 with the skin material 15, the armrest pad can be positioned.
There is an advantage that the armrest pad 14 can be held at an appropriate position without causing the position shift of the 14.

Next, a second embodiment of a vehicle door trim according to the present invention will be described with reference to FIGS. In the present example, the automobile door trim 20 is formed by integrally coating the outer surface of a flat core material 21 with a pad material 22 such as polyurethane foam on the outer surface thereof with a skin material 23 such as a PVC sheet. The door trim main body 24 is configured by winding and adhering the peripheral edge of the skin material 23 onto the back surface side of the core material 21.
Then, a separately formed armrest pad 25 is attached to substantially the center of the door trim body 24 to form the vehicle door trim 20.

The armrest pad 25 is composed of a pad 26 formed by molding polyurethane foam into a desired shape by molding, and a skin 27 covering the front surface side of the pad 26, and a protrusion 28 on the back surface side of the pad 26. It is provided as one
The projecting portion 28 penetrates an opening 29 formed in the core material 21 and projects to the rear surface side of the door trim 20, and a tip portion 28a thereof is in contact with the surface of the door inner panel 30. The reference numeral 31 is a core material.
21 Shows a spacer bonded to the back surface.

Therefore, also in this example, the pad of the armrest pad 25
26 Since the protrusion 28 is provided on the back side and the conventional spacer is also used by this protrusion 28, the cushion material located on the back side of the armrest is manufactured in a separate process, and the step of attaching to the back side of the door trim can be omitted. In addition to reducing the manufacturing cost, an effective spacer function can be obtained by following the surface shape of the door inner panel 30 and constantly maintaining the contact state between the protrusion 28 and the surface of the door inner panel 30. It has the same effect as.

Further, a core material 32 as shown in FIG. 5 may be inserted inside the pad 26 of the armrest pad 25 so that the armrest pad 25 can maintain an appropriate shape even when a large external force is applied.

<Effect> As described above, according to the vehicle door trim of the present invention, the protrusion is provided on the back side of the armrest pad attached to the core, and the protrusion is passed through the opening provided in the core of the door trim. Since it is made to project to the back side and the tip portion is brought into contact with the door inner panel, the cushion material conventionally installed between the door trim and the door inner panel can be omitted. In addition to saving the cost, the step of attaching the cushion material to the door trim side can be omitted, and the manufacturing process can be significantly shortened, resulting in a significant cost reduction.

Furthermore, since the protrusions that have spacer functions are molded integrally with the armrest pad by molding, they can handle the complicated surface shape of the door inner panel, and therefore, a superior cushioning effect can be obtained compared to conventional urethane cut products. There is an advantage that can be.
