Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in a door trim that constitutes the lining of a door of a vehicle, such as an automobile.

[Conventional technology]

2. Description of the Related Art In a vehicle such as a passenger car, the front door of the vehicle is formed as shown in FIG. That is, 1 is a door body, T is a door trim, 3 is a weather strip, 4 is a door glass, 5 is a door inner handle, 6 is a handle for raising and lowering the door glass, 7 is a door bracket, and 8 is an armrest. In particular, the door trim T is conventionally constructed as shown in FIG. 4 or FIG. 5.

First, starting with the one shown in FIG. 4, reference numeral 10 denotes a door inner plate made of a metal plate. This door inner plate 1
The lower surface of 0 is the board base material 11 that constitutes the lower part.
covered by. 12 is this board base material 11
This is a top base material whose lower end is interposed between the back side of the upper end and the door inner plate 10, and which extends over the upper part. The surfaces of the board base material 11 and the top base material 12 are covered with a lining material 15 consisting of a pad 13 and a skin 14 covering the surface thereof. The upper end portion of this lining material 15 is overlapped with the upper end bent portion of the upper base material 12. Then, only the upper end portion of the skin 14 is attached to the door inner plate 10.
It comes into contact with the upper bent portion of the door and is attached to the door inner plate 10 by a support fitting 16. This support fitting 16 is
It supports a weather strip 17 with which the door glass 4 (not shown) slides. That is, a claw portion 18 is cut and formed on the support fitting 16, and this claw portion 18 is formed by cutting out and raising the claw portion 18 between the skin 14 and the door inner panel 10.
The support fitting 16 and the skin 14 are attached to the door inner plate 10 by inserting the support fitting 16 into a mounting hole 19 that is drilled over the entire length and bending the protruding portion.
This type of door trim structure is applied to relatively high-end passenger cars.

In the case shown in FIG. 5, a lower lining material 22 consisting of a pad 20 and a skin 21 is coated on the surface of a board base material 11 constituting the lower portion. Door inner plate 10a extending to the upper part of this board base material 11
is directly covered with a top lining material 25 consisting of a pad 23 and a skin 24. In addition, the door inner plate 10
A holding plate 26 is interposed between the upper end of A and the upper end of the skin 24, and a mounting hole 27 is provided therebetween. Reference numeral 28 denotes a supporting metal fitting to which the weather strip 17 is attached, and a claw 29 protruding from the back side of this metal fitting is inserted and fixed. This type of door trim structure is often applied to relatively inexpensive light cars or trucks.

[Problem that the invention attempts to solve]

However, the structure shown in FIG. 4 has a good appearance because both the lower part and the top part of the lining material 15 are integrated, but it requires the top base material 12 as well as the board base material 11, and is particularly difficult to use. Since the upper base material 12 supports the pad 13 and the skin 14, a material with high rigidity must be selected.
For example, it is a board material or sheet metal made of wood powder hardened with a resin material. For this reason, the weight of the door itself becomes large, force is required to open and close the door, and the cost inevitably tends to increase.

Furthermore, in the structure shown in FIG. 5, the weight of the door is reduced because the atsupah base material 12 is not required, but the lower lining material 22
The boundary between this and the Atsupa lining material 25 is clearly noticeable and spoils the aesthetic appearance.

As described above, each of the conventional door trim structures has its advantages and disadvantages, and there is a strong demand for a door trim that eliminates the disadvantages.

The present invention was developed with attention to these problems, and its purpose is to reduce the weight, improve the appearance, and make it easier to attach the weather strip and to the inner panel of the door. The present invention also aims to provide a reliable door trim structure.

[Means for solving problems]

That is, in the present invention, the upper end of the door inner plate is bent into a substantially inverted U-shaped cross section, a notch is opened in the upper bent part, and a board base material is used to cover the lower surface of the door inner plate. The surface of the board base material and the door inner plate surface of the upper part formed on the upper part of the board base material are integrally formed with a lining material consisting of a pad and a skin covering the surface of the pad. cover, fix a plate along the upper end of these pads and the skin, provide a mounting hole in this plate, insert the claw part of the support fitting for attaching the weather strip into the mounting hole of the plate, and bend it. Attach it using the mounting part of the sheet metal clip to elastically sandwich the plate and the end of the lining material, and insert the fixing part of the sheet metal clip into the notch of the door inner plate to attach a part of the door inner plate. This is a door trim structure that is characterized by elastically clamping.

[Effect]

According to such a structure, since there is no base material in the top part, the weight is reduced, and since the lining material integrally covers the lower part and the top part, the appearance is good. Moreover,
The weather strip is securely attached to the support metal fittings using claws as in the past, and the lining material is securely attached to the door inner plate using sheet metal clips, completely separately from this.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. Since the shape and structure of the door was previously explained based on FIG. 1, that figure will be applied and new explanation will be omitted here. However, this specific structure is as shown in FIGS. 2 and 3.

That is, 30 is a door inner plate. The lower part of the door inner plate 30 is recessed inwardly, and a board base material 31 forming a lower part is attached to the surface thereof. Further, the upper end of the door inner plate 30 is bent to have a substantially inverted U-shaped cross section, and a plurality of notches 32 (only one is shown) are opened at a predetermined interval in the upper end bent portion. A pad 33 integrally covers the surface of the board base material 31 and the surface of the door inner plate 30 at the top portion formed at the upper portion of the board base material 31, and the surface of the pad 33 is covered with a skin 34. Lining material 35 from pad 33 and skin 34
is configured. A plate 36 is welded along the upper end of the skin 34 extending from the upper end of the pad 33. Attachment holes 37 (only one location is shown) are provided in the plate 36 and the skin 34 at predetermined intervals. 38 is a weather strip, and this weather strip 38 is attached and fixed to a support fitting 39. Claw portions 40 are cut and raised at predetermined intervals on the back side of the support fitting 39. The claw portion 40 is inserted into the mounting hole 37 with the weather strip 38 attached, and is bent and mounted. Further, 41 is a sheet metal clip, which has a width dimension that allows it to be inserted into the notch 32,
It is integrally curved to open upwardly and downwardly. To explain, this is formed by continuously forming a substantially U-shaped cross section and a substantially inverted U-shaped cross section, with the upper open portion serving as the attachment portion 42 and the lower open portion serving as the fixing portion 43. The mounting portion 42 is attached to the epidermis 3.
The welded portions of the plates 36 of No. 4 are elastically clamped.
Further, the fixing portion 43 of the sheet metal clip 41 is inserted into the notch 32 of the door inner plate 30, and elastically clamps a portion of the door inner plate 30.

Next, a method for assembling the door trim constructed in this way will be explained. A board base material 31 is attached to the lower surface of the door trim inner plate 30 formed into a regular shape, and this board base material 31 and the board base material 31
A lining material 35 consisting of a pad 33 and a skin 34 is attached over the surface of the door inner plate 30, which is the upper part of the door. A plate 36 is welded along the back side of the skin 34 extending upward from the upper end of the pad 33 to temporarily secure it. At this time, the mounting holes 37 are communicated with each other. Next, the support metal fitting 39 with the claw portion 40 cut out is attached to the weather strip 38. In this state, the support fitting 39 is opposed to the plate 36, and the claw portion 40 is inserted into the mounting hole 37. The weather strip 38 is attached to the lining material 35 by bending the claw portion 40 projecting toward the back side of the plate 36 along the plate 36. Furthermore, plate 3
Attach the sheet metal clip 4 to the overlapping part of 6 and the outer skin 34.
The mounting portion 42 of 1 is elastically clamped. A portion of this attachment portion 42 will intervene between the skin 34 and the support fitting 39. Finally, the lining material 35 to which the weather strip 38 and sheet metal clip 41 are attached
is attached to the door inner plate 30. That is, the fixing part 43 of the sheet metal clip 41 is inserted into the notch 32 provided in the door inner plate 30, and the lower part of the notch 32 is elastically clamped. This results in the installation of a so-called door trim.

According to such a structure, even when the door is opened and closed, there is no base material at the top, so the door is lightweight and can be opened and closed easily. Since the weather strip 17 is attached using the claw portion 40, it is highly reliable. Furthermore, since the attachment of the lining material 35 to the door inner plate 30 is done completely separately from the attachment of the weather strip 38, the work is easy.

[Effect of idea]

As explained above, according to the present invention, the weight of the door can be reduced, the weather strip and the door inner plate can be easily and securely attached, and the workability can be improved and costs can be reduced. .
