Description

[Detailed description of the invention] (Industrial application field) The present invention is a lining material for a vehicle door that covers the inside plate of a vehicle door, such as an automobile door, from the front part to the handrail part of the upper edge. This is related to the improvement of

(Prior art) A laminated skin material made of polyurethane foam and skin is attached to one side of the mounting board with the upper part extending from the upper edge of the mounting board, and a part of it is attached to the mounting board to form a linear welded part. A vehicle door lining material in which a weather strip is attached to the upper edge of the skin material is already known from Japanese Utility Model Application Publication No. 54-87518.

(Problem to be solved by the invention) However, because the upper covering material of the conventional one is a laminated skin material made of flexible polyurethane foam and skin, the shape retention of the upper part extending from the upper edge of the mounting board is poor. In addition, workability is poor as it tends to wrinkle due to the difference in expansion and contraction between the polyurethane foam and the skin, and if the polyurethane foam is thick, welding strength for linear welds cannot be obtained, etc. The problem remains.

(Means for Solving the Problems) The present invention relates to a lining material for a vehicle door that does not have such problems, and includes a lining material and a skin material on one side of a mounting board above the upper edge of the mounting board. In the lining material for a vehicle door, the lining material is extended and attached, a part of which is welded to the mounting board with a linear welded part, and a weather strip is attached to the upper edge of the skin material, The lower bed material is made of flexible polyurethane foam attached to the mounting board, and the lower part is attached to the upper part of the mounting board with the lower edge close to the upper edge of the lower bed material. The present invention is characterized in that it is made of an upper bed plate with excellent shape, and that the linear welded portion is located at the boundary between the lower bed sheet and the upper bed board.

(Function) The lining material of such a vehicle door may be used in the same manner as conventional door lining materials of this type by covering the door from the front surface to the upper handrail.

(Embodiments) Next, the present invention will be described in detail with reference to illustrated embodiments.

Reference numeral 1 denotes a mounting board, and on one side of the mounting board 1, a lining material 2 and a skin material 3 are attached with the upper part extending from the upper edge of the mounting board 1, and a part of them is mounted. The board 1 is welded to the board 1 with a linear weld 4, and a weather strip 5 is attached to the upper edge of the skin material 3. hardness is 40~
A lower bed material 2b made of flexible polyurethane foam with an angle of about 55 degrees (measured value according to Japan Rubber Association standard SRIS-0101) is attached to the upper part of the mounting board 1 with its lower edge approaching the upper edge of the lower bed material 2b. The hardness of polyethylene foam etc. with the lower part added is 55~
It is divided into an upper bed plate that retains its shape at an angle of about 70 degrees. On the other hand, the skin material 3 is also attached to the surface of the lower bed material 2b with its upper end slightly overhanging its upper edge, and is attached to the surface of the upper bed board 2a by means such as welding or gluing. The upper bed plate 2a
Upper skin 3a whose lower end slightly overhangs the lower edge of
The overlapping portion of the upper skin 3a and the lower skin 3b, which corresponds to the boundary between the lower bedroll material 2b and the upper bedsheet 2a, is welded to the mounting board 1 as a linear welded portion 4. A weather strip 5 is attached to the upper edge of the upper skin 3a. In addition, 6 in the figure is a belt core fixed as necessary to the upper edge of the skin material 3 to which the bed material 2 is attached, and is the weather strip 5 in the illustrated embodiment.
is attached to the upper edge of the skin material 3 with a clip 7 having one end secured to the band core 6.

When a vehicle door constructed in this way is constructed by covering the door from the front surface of the inner panel to the upper handrail, similar to the lining material of conventional vehicle doors of this type, Since the skin material 3 exhibits a buffering effect, it is excellent in safety, and the weather strip 5 also exhibits the effect of preventing rainwater from entering and vibration of window glass. 2, the upper part extending above the upper edge of the mounting board 1 is used as the upper bed plate 2a, which is made of polyethylene foam that has not only elasticity but also shape retention, so it does not lose its shape and is durable. In addition, since the upper skin 3a is integrally attached to the upper bed board 2a by means such as welding or gluing, the properties of the material and the material properties make it easy to move along the arc of the handrail of the door inner board. Wrinkling that is likely to occur due to the difference in the amount of curvature between the front side and the back side can be accurately prevented.In contrast, the lower bed material 2b that covers the mounting board 1 is made of a flexible polyurethane foam that is inexpensive and has good cushioning properties. Therefore, there are no performance or price issues. Moreover, since the linear welded part 4 is located at the boundary between the lower bedsheet 2b and the upper bedboard 2a, the adhesive strength will not be weakened by the bedside material interposed in between, and the strength of the welded part will be sufficient. There is no separation and no wrinkles occur in this area. Moreover, when working on covering the inner door panel, the upper skin 3a and the upper bed board 2a are attached in advance, and the lower bed material 2b and the lower skin 3b are sequentially attached to the mounting board 1, and the upper part is attached above it. Attach the upper skin 3a with the bed board 2a so that the lower edge of the upper bed board 2a approaches the upper edge of the lower bed material 2b, and overlap the overhanging ends of the upper skin 3a and the lower skin 3b, Since this part can be connected and integrated by forming the linear welded part 4 using a high-frequency welding machine or the like, mass production becomes easy.

(Effects of the invention) As is clear from the above description, the present invention has good shape retention in the part extending from the upper edge of the mounting board, so it is not only durable but also less prone to wrinkling and improves workability. Moreover, it has various advantages such as excellent welding strength of the linear welded part, and has great practical value as a solution to the problems of conventional vehicle door lining materials of this type. It is something.
