Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a trunk trim for an automobile.

Recently, even in the trunk room of a passenger car, a trim member has been installed on the inner panel of the trunk room.

FIG. 1 shows the trunk room 2 of the automobile 1 and the trunk room trim 3 disposed therein. It is each divided into a funnel 4, a trunk rear finisher 5, a trunk side finisher 6, 6, and a trunk floor finisher 7,
Each of these members is made up of a combination of flat parts and molded parts made by laminating a core material with a skin material such as carpet.

However, in the case of the trunk room trim in which each member is separately formed to match the shape of each part of the trunk room 2, the number of parts is large because each member is formed separately as described above. Further, when each member is assembled on an automobile assembly line, each member must be attached and assembled separately in the trunk 2 of the automobile 1, which has the disadvantage of requiring a large number of assembly steps.

In addition, when assembled into one luggage compartment trim 3 in this way, the assembly is completed with the joined edges of each member brought together, but there may be gaps or edges exposed at the joined parts. Therefore, it was inferior in appearance.

This invention was made in view of the problems of the conventional trunk room trim as described above, and each piece of the inner panel is expanded to correspond to the three-dimensional shape of the inner panel that constitutes the floor surface and four surrounding walls in the trunk room of an automobile. The number of parts can be reduced by integrating the pieces into a single piece and making it possible to fold and unfold the joint edges of each piece.In addition, during the assembly process, the pieces can be simply raised from the folded state. The present invention provides a trunk room trim that can be completely assembled into an automobile.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIG. 2 and the following drawings.

FIG. 2a shows a flexible skin material 10 constituting a trunk room according to the present invention.

In Figure a, the skin material 10 is made of a material such as carpet, non-woven fabric, woven fabric, or PVC sheet, and this skin material 10 covers a trunk floor portion 11, a front portion 12 and a rear portion 1 formed before and after the trunk floor portion 11.
3, and side parts 14, 14 formed on the left and right sides of the trunk floor part 11,
This thing corresponds to the three-dimensional shape of the above-mentioned trunk room 2, and each part is trimmed and cut into a shape that expands the three-dimensional shape.

Further, one end is joined to the approximate center of the trunk floor portion 11, and an arcuate cut 11a is formed.
A spare tire cover part 15 is formed inside the spare tire cover part 15, which can be opened and closed using the above-mentioned one end as a hinge.

In addition, in each piece formed as described above, the portion indicated by a dotted line in the figure indicates a folding line or a winding end for winding onto the back side of a core material to be described later.

Corresponding to the skin material 10 configured as above,
The core material attached to the back side of this is formed into a shape corresponding to each part.

The one shown in FIG. 2b shows the core material to be attached to the back surface of each part of the skin material 10, which is a press board, a composite resin board (wood powder on polyolefin). board)
Alternatively, it can be selected from various materials such as a single plastic board or a plastic hollow core board (board shaped like cardboard), each of which is separately stamped and formed into a floor shape as shown in the figure. It comprises a plate 111, a front plate 112, a rear plate 113, side plates 114, 114, and a spare tire cover plate 115 formed by hollowing out the center of the floor plate 111 in a substantially arc shape.

Further, at appropriate positions of the side plates 114, 114, pressed portions 114' are formed symmetrically, and these pressed portions 1
Each side plate can be bent using the hinge 14'.

The core material formed into the shape of each of these parts is
The skin material is attached to the surface surrounded by the dotted line in each part of the skin material 10 described above so that the skin material extends along the outer periphery of each piece of the core material, and the outer periphery is glued as necessary. It is integrated by wrapping it around the back side as a margin.

FIG. 3 shows the form of the integrated luggage compartment trim 100. In the figure, the part indicated by a set of dots indicates the part where the above-mentioned skin material is visible. That is, at the front and rear ends of the side plates 114 and at the joint edges with the floor plate 111, the skin material is not folded back to the back surface thereof, and the skin material is left between each plate with sufficient gaps. This part, that is, the continuous part of each part of the skin material 10 is connected to the hinge 10.
Each piece can be folded and unfolded with respect to the floor part 11 as a, 10a, . . . . Further, at the front and rear of the side plate 114 and at the joint with the floor plate 111, the extending portion 10 of the skin material 10
b, 10b, . . . are configured with overlapping pieces so as to overlap adjacent joint portions when assembled to the inner panel.

FIG. 4 shows the trunk trim constructed as described above in an assembled state. In this case, the above-mentioned extension pieces 10b are rolled inward as shown in FIG. 5, so that the cut portion formed by each piece is covered.

In addition, as shown in FIG.
4' serves as a hinge so that the side part can be woven into a desired curved surface.For example, by forming such a curved surface by pressing the side plate, the above-mentioned It is formed in a shape that conforms to the protruding end of, for example, a wheel house portion of the trunk room 2.

Note that, in addition to a large protrusion such as the foil house, for example, a small curved protruding end may be formed in the trunk room 2. The portion surrounded by line B in FIG. 3 is formed corresponding to the bulging end, and the floor plate 111 and side plate 11 here
A substantially arc-shaped cutout is formed at the joint portion 4. In the actually assembled state, as shown in more detail in the right end of FIG. 4 and FIG.
1 and the side plate 114 are shaped so that they escape, and the skin material comes into direct contact with these parts, and the skin material deforms due to its flexibility in accordance with the bulging end of the inner panel. It's becoming possible.

Note that the explanation above is based on the case where the inner panel has only one protruding end, but if there are protruding parts in other parts, cut outs should be made in each part of the core material accordingly. If the bulging end is covered with only the skin material, the luggage compartment trim will be formed in a shape that perfectly follows the curved shape of the luggage compartment.

Next, FIG. 7 shows a cross section of the spare tire cover portion, in which a spare tire cover plate 115 is adhered to the back surface of the spare tire cover portion 15 of the skin material 10 described above. , and a joint piece between the spare tire cover part 15 and the floor part 11 (shown by a dotted line in FIG. 2)
is formed so that it can be opened and closed with respect to the floor plate 115 using a hinge, and an edge frame 20 is fitted to the arc-shaped outer periphery of the floor plate 115, so that, for example, the foil can be used as a spare tire cover. The floor part 11 and its spare tire cover can be kept on the same plane even if they are not housed in the lower surface of the part 15.

And like this trunk room trim 100
When assembled in the trunk,
At least a means for fixing is required, but as a preferred example in this case, as shown in FIG. In this state, fold it back to the rear side panel 2a of the trunk compartment 2, and attach the welt 3 to the folded part.
0, this part is fixed and the end face is hidden at the same time, and the purpose of fixing the trunk trim and improving the appearance can be achieved at the same time.

As explained above in the embodiments, in the trunk room trim according to the present invention, each part constituting the trunk room is integrally constructed, and the continuous edges of the skin material constituting each piece are hinged. Since each part can be folded and unfolded, for example, the trunk trim is formed into an unfolded shape as shown in Fig. 3, and when transporting it, the rear, front, and side sections are separated from the floor. If it is folded, it can be transported in a completely flat state. When assembling this folded state into the trunk of a car on an assembly line, first place the floor section in the folded state in the trunk, and then assemble the side and side sections in the reverse order. By unfolding the rear and front sections, the vehicle can be unfolded into a shape that follows the shape of each wall of the inner panel that makes up the trunk.

Therefore, in this invention, by integrating the members as described above, the number of parts is extremely reduced compared to the conventional method in which each member constituting the luggage compartment trim is formed separately, and there are no transportation problems. It also has the advantage that even when it is assembled into a trunk room on an assembly line, it can be assembled with a single touch.

In addition, as in the embodiment, if the edge of the skin material is extended at the joint edge of the cut-out part when assembling the floor surface part and the four peripheral walls, the joint edge can be formed by this extension part. Since assembly can be carried out in a manner that hides the cut-off parts between the edges, compared to the conventional method of assembling each member, the joined edges are less noticeable and appear to be integrated, which improves the appearance. It has various advantages such as:
