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 installed therein. Each is divided into a finisher 4, a trunk rear finisher 5, a trunk side finisher 69, 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 trunk room trim in which each member is formed separately 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 above-mentioned problems with the trunk room trim of a car. By integrating the pieces into one piece so that it can be unfolded, and by making the joint edges of the multiple pieces foldable and unfoldable, the number of parts can be reduced, and during the assembly process, simply raising the multiple pieces from the folded state allows the car to be assembled easily. The installation is completed to provide a trunk trim.

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

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

In the figure (a), the skin material 10 is made of a material such as carpet, nonwoven fabric, woven fabric, or PVC sheet. section 13 and its front section 11
It is composed of side parts 14 and 14 formed on the left and right sides of the trunk compartment 2, and each part is trim-cut integrally in a shape that expands the three-dimensional shape of the trunk room 2, corresponding to the three-dimensional shape of the trunk room 2. .

Further, one end is joined to the substantially medium heat of the trunk floor portion 11, and a circular arc-shaped cut 11a forms a spare tire cover portion 15 whose interior can be opened and closed using the one end as a hinge. .

In addition, in the multi-piece formed as described above, the portion indicated by the dotted line in the figure indicates a folding line or a winding end for winding onto the back side of the core material, which will 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.

What is shown in FIG. 2(b) shows the core material to be attached to the back surface of each part of the skin material 10. The material is selected from various materials, such as a board mixed with wood powder), a single plastic board, or a plastic hollow core board (a board shaped like cardboard), each of which is separately stamped and formed. , as shown in the figure, comprises a floor 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 circular arc shape. This is what I did.

Then, at appropriate positions of the side plates 114 and 114 marked -F, pressed parts 114' are formed symmetrically, and each side plate can be bent using these pressed parts 114' as hinges. It has become.

The core material formed in the shape of each of these parts is pasted on the surface surrounded by the dotted line in each part of the skin material 10 described above, and if necessary, the outer periphery can be used as a glue margin and rolled onto the back side. integrated by.

Figure 3 shows the integrated luggage compartment trim 100.
This shows the form of 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, the skin material is not folded back to the back surface thereof, and the skin material is exposed with a sufficient gap between each plate. This part, that is, the continuous part of each part of the F skin material 10 is connected to the hinges 10a, 10a,
...And the eight pieces can be folded and unfolded against the floor part 11. Further, at the front and rear parts of the side plate 1140 and at the joints with the floor plate 110, the edges of the skin material 10 are extended, and each extension piece 1
0b, 10b, . . . are assembled to the inner panel in such a way that they are sometimes overlapped at adjacent joints.

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

Further, as shown in FIG. 4, the threaded part 114' serves as a hinge, allowing the side part to be woven into a desired curved surface.For example, such a curved surface can be woven into a side plate. By forming it by pressing, it is formed into a shape that conforms to the protruding end of, for example, the wheel house portion of the luggage compartment 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. Line B in Figure 3
The portion surrounded by is formed corresponding to the bulged end, and a substantially arc-shaped cutout is formed at the joint portion of the floor plate 111 and side plate 114 here. In the actually assembled state, the floor plate 111 and side plate 114 in that part escape in correspondence with the bulging part P1 of the inner panel P in the boat trunk 2, as shown in more detail in the right end of Fig. 4 and in Fig. 6. The inner panel has such a shape that the skin material comes into direct contact with that portion, and the skin material can be deformed due to its flexibility in accordance with the bulged end of the inner panel.

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 a part of the spare tire cover, which is attached to the spare tire cover plate 115 on the back side of the spare tire cover part 15 of the skin material 10 mentioned above. The spare tire cover part 15 and the floor part 11 are formed so that they can be opened and closed with respect to the floor plate using a joint piece (shown by a dotted line in FIG. 2) as a hinge, and the floor plate 1
An edge frame 20 is fitted to the arc-shaped outer periphery of 15,
This allows, for example, if the foil is part of the spare tire cover.
This allows the floor part and the spare tire cover to remain on the same plane even if the spare tire cover is not stored on the underside of the tire.

When the trunk room trim 100 is assembled in the trunk room in this way, at least a means for fixing it is required, but as a preferred example in this case, a skin material provided on the rear plate 113 is shown in FIG. is formed to extend from its upper edge, and folded back to the rear side panel 2a of the trunk compartment 2 when assembled inside the luggage compartment 2, and a welt 3 is attached 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 luggage compartment trim according to the present invention, each part constituting the luggage compartment is integrally constructed, and the continuous edges of the skin material constituting the eight pieces 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 surface of the inner panel that makes up the trunk room.

Therefore, in this invention, by integrating 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 individually, and the transportation problem is also solved. Additionally, even when it is assembled into a trunk room on an assembly line, it has the advantage of being able to be assembled with a single touch.

In addition, as in the embodiment, when the floor part and the four peripheral wall parts are assembled in the cut-out part, the joint edge can be formed by extending the edge part of the skin material. Since the parts can be assembled in a manner that hides the parts that have been cut away from each other, the joint edges are less noticeable than when assembling each member in the past, and the appearance is improved, as the joints appear to be integrated. It has various advantages such as
