2. Description of the Related Art Normally, a door trim for an automobile installed in a door panel has a function of improving the interior aesthetics and protecting an occupant against impact from the side. As shown in the drawings, there is a tendency that a door trim for an automobile with a high added value is often used by incorporating a heater device to enhance comfort in winter driving.

A door trim 1 for an automobile includes a core 2 formed by molding a resin plate, a fiber board, or the like into a required shape, and a core 2
And a pad material such as a polyurethane foam and a skin material 4 such as a polyvinyl chloride sheet laminated on the surface side of the sheet.

[0006] The heater device 5 is installed at a place where the occupant can easily touch, as shown by the area indicated by the broken line in FIG. It is attached and fixed via an agent.

In order to efficiently detect the temperature of the heater device 5, a thermostat 6 is installed at the center of the heater device 5, and an opening 2a is opened in the core member 2 at the thermostat 6 mounting portion. In reality, the thermostat 6 is accommodated in the opening 2a, and the mounting plate 6a supporting the thermostat 6 is fixed to the back surface of the core material 2 with rivets or the like.

[0006]

As described above, in the conventional vehicle door trim 1 incorporating the heater device 5, the thermostat 6 is accommodated in the opening 2a of the core member 2, but the surface of the door trim 1 is manually manipulated. It has been pointed out that when touched, the feel of the place where the thermostat 6 is installed is different from that of the other parts, causing a sense of discomfort on the product surface.

In order to attach the thermostat 6,
It is necessary to rive the mounting plate 6a, and this operation must be performed before the pad material 3 and the skin material 4 are crimped to the core material 2, which increases the number of work steps and increases the product cost. A defect has been pointed out.

Further, in order to enhance the cushioning performance of the door trim 1, especially when thickening pad material is attached to a place where the occupant can easily touch, as shown in FIG.
The heater device 5 is sandwiched between the thickening pad 7 and the thickening pad 7. In this case, however, it is necessary to separately open an opening 7 a for accommodating the thermostat 6 in the thickening pad 7. Also in the thick pad 7 installation type, since the thermostat 6 is mounted so as to protrude toward the surface side of the core material 2, the problem of giving a sense of incongruity to the product surface cannot be solved.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an automobile door trim with a built-in heater in which a sheet-like heater device is installed. An object of the present invention is to provide a door trim for an automobile having a high commercial value by simply attaching a thermostat for efficiently performing sensing without giving a sense of incongruity to a product surface.

[0010]

In order to achieve the above object, the present invention comprises a core material surface covered with a pad material and a skin material, and a sheet between the core material and the skin material. In a door trim for a vehicle with a built-in heater in which a heater device of a shape like is interposed, a part of the heater device is bent toward the back side of the core material, and a thermostat is attached to the bent portion. Features.

[0011]

As is evident from the above configuration, since a part of the heater device is bent to the back side of the core material and the thermostat is attached to the bent portion, the thermostat projects to the front side of the core material. As a result, the feel of the product surface is good without giving a sense of incongruity to the product surface.
