Description

Interior trim for vehicles

The present invention relates to a vehicle interior trim.

Conventionally, an interior trim (vehicle interior trim) that covers the inside of a vehicle body panel is known from the viewpoint of decoration and various functions. The interior trim is composed of a base material and a surface layer material (skin, film, resin, etc.) covering one surface of the base material. The surface layer material is pasted simultaneously with the molding of the base material by molding, or is pasted to the base material obtained by molding by a technique such as pressure bonding.

When manufacturing the interior trim by such a method, since the product is manufactured in a state including the surplus area outside the original product shape, it is necessary to cut the surplus area. For the cutting process, for example, a cutter device such as an ultrasonic cutter device is used. For example, Patent Document 1 discloses a trimming apparatus that can cut an outer peripheral terminal portion of a molded product.

In order to cut the surplus area of the outer peripheral end portion by the cutter device, a cut line is set in the outer peripheral end portion of the exterior trim, and a copying surface is provided along the cut line. Since the cutting blade can be guided by placing the cutting blade on the copying surface, the outer edge portion (surplus region) outside the cutting line can be accurately cut.

JP 2008-207391 A

By the way, since the interior trim is provided with complicated modeling, it may be necessary to perform the cutting process by changing the angle of the cutting blade even between the outer peripheral end portions forming adjacent sides. In this case, as shown in FIG. 7, when the outer peripheral terminal portion 120 on the first side is cut along the cut line L11, the cut blade C1 is detached from the interior trim and the angle of the cut blade C1 is changed. The outer peripheral terminal portion 130 on the second side needs to be cut along the cut line L12.

However, this method has the disadvantage of low productivity because it takes time to move from the first side to the second side. Further, when cutting the second side, it is necessary to allow the cutting blade to enter from the outer peripheral terminal portion 120 of the first side on which the cutting process has been performed. At this time, since the position of the cutting blade is not stable, there is a problem that the processing accuracy of the outer peripheral end portion varies.

The present invention has been made in view of such circumstances, and an object thereof is to provide a vehicle interior trim that is excellent in productivity and processing accuracy.

In order to solve such a problem, the present invention provides a trim body that is attached to a vehicle body panel, and an outer edge portion that is provided on the trim body along a cut line that is set on an outer peripheral terminal portion of the trim body and that is outside the cut line. An interior trim for a vehicle having a copying surface that guides the cutting blade when the cutting blade is addressed when the cutting process is performed. In this case, the outer peripheral terminal portion is set with a first outer peripheral terminal portion where the first cut line is set, and a second cut line different from the first cut line, and a side adjacent to the first outer peripheral terminal portion. A copying surface including a first copying surface provided along the first cut line of the first outer peripheral terminal portion and a second cutting line of the second outer peripheral terminal portion. It is comprised by the 2nd copying surface in which the angle of the cut blade provided and addressed differs from the 1st copying surface, and the 3rd copying surface which connects the 1st copying surface and the 2nd copying surface continuously .

Here, in the present invention, it is preferable that the third copying surface has a curved surface shape.

In the present invention, it is preferable that the third copying surface is configured to change the angle of the cutting blade three-dimensionally in accordance with a change in the angle of the cutting blade between the first copying surface and the second copying surface. .

In the present invention, the first copying surface includes a stepped portion in which the thickness of the outer edge portion on the outer side of the trim main body is thinner than the thickness of the general portion on the inner side of the trim main body than the first cut line. The copying surface is preferably formed of a convex rib extending along the second cut line, and the third copying surface is preferably formed by continuing the step portion from the first copying surface to the rib of the second copying surface. .

In the present invention, the trim body is preferably composed of a base material and a surface layer material adhered to one surface of the base material.

According to the present invention, it is possible to provide a vehicle interior trim that is excellent in productivity and processing accuracy.

The door trim 1 is provided with an armrest 2, a door pocket 3, and the like at required positions.

Hereinafter, the features of the interior trim according to the present embodiment will be described using the lower trim 10 as an example. Here, FIG. 2 is a perspective view showing a main part of the lower trim 10 surrounded by the circumference shown in FIG. 1 from the back side. FIG. 3 is a perspective view showing the main part of the lower trim 10 before the cutting process is performed from the back side.

The lower trim 10 includes a base material 11 and a skin material 12 attached to the surface of the base material 11 (design surface on the passenger compartment side). The skin material 12 has both a cushion function and a cover function, for example, and is attached simultaneously with the molding of the base material 11 by mold molding, and is integrated with the base material 11. However, the skin material 12 may be bonded to the base material 11 obtained by molding by pressure bonding or the like and integrated with the base material 11.

As shown in FIG. 3, when the lower trim 10 is manufactured, the product is manufactured in a state including the surplus area W outside the original product shape. Therefore, in the lower trim 10 as the final product (see FIG. 2), the surplus The area W has been removed by the cutting process. For the cutting process, for example, an ultrasonic cutter device is used.

In order to cut the surplus area W of the outer peripheral terminal portion by the ultrasonic cutter device, a cut line is set in the outer peripheral terminal portion of the lower trim 10, and the lower trim 10 is provided with a copying surface along the cut line. Yes. The cut line indicates the cutting direction of the cutting blade of the ultrasonic cutter device, and corresponds to the original product shape. Cut processing is performed along the cut line, and the outer edge portion (the surplus area W) outside the cut line is removed, whereby the lower trim 10 is completed.

Specifically, among the outer peripheral terminal portions of the lower trim 10, the first cut line L1 is set in the first outer peripheral terminal portion 20 that forms one side on the upper side of the rear terminal portion. The first outer peripheral terminal portion 20 is provided with a first copying surface 21 along the first cut line L1. The first copying surface 21 is composed of a step portion in which the thickness T2 of the outer edge portion outside the base material 11 is thinner than the thickness T1 of the general portion inside the base material 11 with the first cut line L1 as a boundary. ing. The height of the stepped portion, that is, the first copying surface 21 (its width) can be set in the range of 0.2 mm to 3.0 mm.

Moreover, the 2nd cut line L2 is set in the 2nd outer periphery terminal part 30 which makes the edge | side (one side of an upper terminal part rear side) adjacent to the 1st outer periphery terminal part 20 among the outer periphery terminal parts of the lower trim 10. Yes. The second outer peripheral terminal portion 30 is provided with a second copying surface 31 along the second cut line L2. The second copying surface 31 is composed of a convex rib extending along the cut line. The height of the rib can be formed in the die-cutting direction, so there is no upper limit restriction and can be set at 0.2 mm or more. The second profile surface 31 is configured such that the angle of the cut blade is different from that of the first profile line 21 because the angle of the cut blade differs between the first cut line L1 and the second cut line L2. .

Further, as one of the features of this embodiment, the lower trim 10 is provided with a third copying surface 41 that continuously connects the first copying surface 21 and the second copying surface 31. The third copying surface 41 has a curved surface shape, and for example, the radius of curvature is set in the range of 2 mm to 10 mm. The third copying surface 41 advances the cutting blade while being directed to the third copying surface 41, so that the cutting blade can be moved in accordance with the angle change of the cutting blade between the first copying surface 21 and the second copying surface 31. It is configured to change the direction three-dimensionally. In the present embodiment, the third copying surface 41 is configured by continuing the above-described stepped portion from the first copying surface 21 to the rib of the second copying surface 31.

Hereinafter, the cutting process for the outer peripheral terminal portion of the lower trim 10 will be described. Here, FIG. 4 is an explanatory view schematically showing changes in the cutting blade C. FIG. FIG. 5 is a cross-sectional view schematically showing the state of the cutting blade C. FIG. 5 (a) shows the AA cross section shown in FIG. 4, and FIG. 5 (b) shows the BB cross section shown in FIG. . Moreover, FIG. 6 is explanatory drawing which shows typically the cross section cut by the cutting process.

First, the first outer peripheral terminal portion 20 is cut. The cutting blade C is advanced in the direction indicated by the broken-line arrow in a state where it is addressed to the first copying surface 21. Since the cutting blade C is guided by the first copying surface 21, it advances along the first cutting line L1.

Next, when the cutting blade C reaches the end of the first copying surface 21, the cutting blade C moves forward in the direction indicated by the broken-line arrow in a state of being addressed to the third copying surface 41. A third copying surface 41 is provided between the first copying surface 21 and the second copying surface 31 so as to be continuous between them. For this reason, the cutting blade C is advanced from the angle corresponding to the first copying surface 21 to the angle corresponding to the second copying surface 31 by moving the cutting blade C forward while being addressed to the third copying surface 41. It will change. Due to this change in angle, when the cutting blade C enters the second outer peripheral terminal portion 30, the cutting blade C is properly addressed to the second copying surface 31.

Then, the second outer peripheral terminal part 30 is cut. The cutting blade C is advanced in the direction indicated by the broken line arrow while being directed to the second copying surface 31. Since the cutting blade C is guided by the second copying surface 31, it advances along the second cutting line L2.

Through the above steps, the outer edge portion (excess region W) outside the cut lines L1, L2 is cut by the cutting process. The hatched area shown in FIG. 6 indicates an area cut by the cutting blade C. Thereby, the lower trim 10 corresponding to the product shape is completed.

Thus, the lower trim 10 of the present embodiment is provided on the trim body along the trim body attached to the door inner panel and the cut line set on the outer peripheral terminal portion of the trim body, and the outer edge portion outside the cut line. When the cutting process is performed, the cutting blade C is addressed so as to guide the cutting blade C.

Here, the outer peripheral terminal portion is set with a first outer peripheral terminal portion 20 in which the first cut line L1 is set and a second cut line L2 different from the first cut line L1, and the first outer peripheral terminal portion 20 is set. And a second outer peripheral terminal portion 30 that forms an adjacent side. The copying surface is provided along the first copying surface 21 provided along the first cut line L1 of the first outer peripheral terminal portion 20 and the second cutting line L2 of the second outer peripheral terminal portion 30. A second copying surface 31 in which the angle of the cutting blade C directed to the surface is different from that of the first copying surface 21, and a third copying surface 41 that continuously connects the first copying surface 21 and the second copying surface 31; , Is composed of.

According to this configuration, the third copying surface 41 is provided so as to continuously connect between the first copying surface 21 and the second copying surface 31. For this reason, when moving from the first cut line L 1 to the second cut line L 2, the cut blade C moves forward to the first copying surface 21 by moving the cutting blade C forward to the third copying surface 41. It will naturally change from the corresponding angle to the angle corresponding to the second copying surface 31. Due to this angle change, when the cutting blade C enters the second outer peripheral terminal portion 30, the cutting blade C is properly addressed to the second copying surface 31.

For this reason, when moving from the first outer peripheral terminal portion 20 on the first side to the second outer peripheral terminal portion 30 on the second side, it is necessary to detach the cutting blade C from the lower trim 10 and change the angle of the cutting blade C. Absent. Therefore, the time for shifting from the first outer peripheral terminal portion 20 to the second outer peripheral terminal portion 30 can be shortened. Moreover, when cutting the 2nd outer periphery terminal part 30, it is not necessary to make the cutting blade C approach again from the outer periphery terminal part 20 of the 1st edge in which the cutting process was performed. Accordingly, it is possible to solve the problem that the cutting position is not stable and the processing accuracy of the outer peripheral terminal portion varies. Thus, the lower trim 10 excellent in productivity and processing accuracy can be provided.

In the present embodiment, the third copying surface 41 has a curved surface shape.

According to this configuration, the angle of the cutting blade C can be changed smoothly. Thereby, the cut surface can be finished with good aesthetics.

In the present embodiment, the third copying surface 41 changes the direction of the cutting blade C three-dimensionally in accordance with the change in the angle of the cutting blade C between the first copying surface 21 and the second copying surface 31. It is configured.

According to this configuration, even when the angle of the cutting blade C is three-dimensionally changed between the first copying surface 21 and the second copying surface 31, the angle of the cutting blade C is changed to the first copying surface. It is possible to naturally change from the surface 21 to the second copying surface 31. Therefore, it is not necessary to detach the cutting blade C from the lower trim 10 and change the angle of the cutting blade C when shifting from the first outer peripheral terminal portion 20 to the second outer peripheral terminal portion 30.

In the present embodiment, the first copying surface 21 is a step in which the thickness T2 of the outer edge portion outside the trim body is thinner than the thickness T1 of the general portion inside the trim body, with the first cut line L1 as a boundary. It consists of parts. On the other hand, the second copying surface 31 is composed of a convex rib extending along the second cut line L2. Then, the third copying surface 41 is configured such that the stepped portion is continuous from the first copying surface 21 to the rib of the second copying surface 31.

According to this configuration, the third copying surface 41 can be appropriately formed so that the direction of the cutting blade C changes three-dimensionally.

In this embodiment, the trim body is composed of a base material 11 and a skin material (surface layer material) 12 adhered to the surface (one surface) of the base material 11.

In the trim main body having this configuration, the surplus area W that protrudes outward from the original product shape is produced in the middle at the time of production, but such surplus area W can be appropriately cut. Thereby, the productability of the lower trim 10 manufactured by the cutting process can be improved.

The vehicle interior trim of this embodiment has been described above, but the present invention is not limited to this embodiment, and various modifications can be made within the scope of the invention. In the present embodiment, the lower trim is exemplified, but the present invention can also be applied to various door trims including an upper trim, and can also be applied to various vehicle interior trims such as a pillar trim (pillar garnish).
