Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile interior skin material used as a skin material for seats, door trims and the like, and more particularly to a brushed interior skin material.

[0002]

2. Description of the Related Art Synthetic or natural leather materials or fabrics are used as a skin material for covering the surfaces of automobile seats, door trims, floor surfaces and the like. For example, according to Japanese Patent Application Laid-Open No. 61-138751, a pearl fabric, which is a kind of knitting used for fabrics of clothes, is used as a skin material for an interior of an automobile, and the pearl fabric covers the surface of a seat or a door trim. In this case, by making the texture pitch of the pearl woven fabric different between the portion that covers the flat portion and the portion that covers the corner portion of the seat or door trim, it is possible to prevent the texture pitch at the corner portion from becoming coarser than that at the flat portion. By configuring the weave pitch to be the same in all parts of the seat and door trim,
It is designed to improve the appearance.

[0003]

By the way, as a skin material for the interior of an automobile as described above, a napped skin material such as a pile fabric is used. This kind of napped skin material is Compared with other fabrics, it has a richer three-dimensional effect due to the difference in light and shade of color, the difference in gloss due to the reflection and absorption of light, and the shallowness of color.
It has excellent slipperiness or feel due to its large coefficient of friction, and is widely used as a skin material such as sheets.
However, in the napped skin material, the reflection and absorption states of light change depending on the napped state, and a so-called white blur state in which the surface is partially white is apt to occur. The original color of the sexual skin material is impaired, the appearance is deteriorated, and it becomes a factor of deteriorating the sense of quality.

Therefore, conventionally, by making the fiber material constituting the napped skin material semi-matt or frosted, the amount of surface reflection of the napped skin material is reduced as a whole to cause white blur. However, in this case, the gloss of the napped skin material is lost and the excellent properties originally possessed by the skin material are impaired,
Even in this case, the appearance is deteriorated and the quality is deteriorated.

Therefore, the present invention suppresses white blurring on the surface of the napped skin material as much as possible when the napped skin material is used as an interior skin material for covering the surface of an automobile seat or door trim. The purpose is not to spoil the original color of.

[0006]

In order to solve the above problems, the present invention is characterized in that it is configured as follows.

The feature is that the skin material is raised toward the rear side window side close to each seat.

The invention according to claim 4 of the present application (hereinafter,
A fourth invention) is characterized in that the hair tips of the napped skin material according to the first to third inventions are formed in a sharp shape.

[0012]

According to each of the above inventions, the following effects can be obtained.

First, according to the first aspect of the present invention, the napped skin material used for the interior of an automobile is napped in the direction of incidence of external incident light mainly incident on the surface thereof, and the napped skin The grain direction of the material is stretched toward the incident direction side of the external incident light.

By the way, the inventor of the present invention irradiates the surface of the napped skin material with the inspection light at a predetermined incident angle, and in the vertical plane passing through the inspection light and the normal line, 90 degrees to the right and left around the normal line. As a result of measuring the distribution state of the reflectance of the inspection light in each part within the range of °, the retroreflection at the time of fluffing (reflected along the incident direction) as compared with the time of raising the above-mentioned raising skin material
It was found that the greater the amount of reflection in the direction and the greater the difference in the amount of reflection in the retroreflective direction between the fluff and the raised hair, the more noticeable the white blur on the surface of the raised skin material. Then, when the incident direction of the inspection light and the normal direction of the napped skin material are directed substantially in the same direction, the difference in the amount of reflection in the retroreflection direction between the napped and raised of the napped skin material. Becomes larger, and white blurring on the surface of the napped skin material becomes noticeable. As described above, according to the first invention, the napped skin material is externally incident in the normal direction. Since it is stretched toward the light incident direction side, the difference in the reflection amount in the retroreflective direction between the bristling and raising of the napped skin material is reduced, which causes white blurring. It is prevented that the original color of the napped skin material is prevented from being impaired, and the high-class feeling is not deteriorated.

According to the second aspect of the invention, in a vehicle in which the windows are arranged substantially symmetrically on the left and right sides of the vehicle body, the napped skin material is napped toward the left and right window sides with the centerline in the vehicle front-rear direction as a boundary. As a result, the napped skin material is raised in the direction of incidence of externally incident light that enters the vehicle mainly through the left and right windows, increasing the amount of reflection in the retroreflective direction during raising. As a result, the difference in the amount of reflection in the retroreflective direction between raised and fluffed hair is reduced, white blur is suppressed, and the original color of the napped skin material is prevented from being impaired. It does not deteriorate the quality.

Further, according to the third aspect of the present invention, the raised skin material covering the left and right front seats is provided on the pillar portion side between the side portion of the front window and the front portion of the front side window which are close to the respective front seats. Since it is fluffed toward, the napped skin material is raised in the incident direction of the external incident light that is mainly incident on the surface of the left and right front sheets from the pillar side, The amount of reflection in the retroreflective direction increases, which reduces the difference in the amount of reflection in the retroreflective direction between raising and fluffing, suppressing white blur, and raising the left and right rear sheets. Since the elastic skin material is raised toward the rear side window side close to each rear seat, the incident direction of the external incident light mainly incident on the surface of the left and right rear seats from the rear side window. The napped epidermal material will be napped toward it, and the amount of reflection in the retroreflective direction during napping will increase, which results in the difference in the amount of reflection in the retroreflective direction between nap raising and bunting. Is suppressed and white blurring is suppressed, and the original color of the napped skin material that covers the surfaces of the left and right front seats and rear seats is prevented from being impaired, and the high-class feeling is not deteriorated.

In particular, according to the fourth aspect of the present invention, since the hair tips of the napped skin material have a sharpened shape, the napped skin material has a sharper shape than that when the napped skin material has a flat shape. The amount of reflection in the retroreflective direction will increase, and the difference in the amount of reflection in the retroreflective direction between raised and fluffed fibers will decrease, which causes white blurring on the surface of the raised skin material. Suppression is prevented and the original color of the skin material is prevented from being impaired, and the high-class feeling is not deteriorated.

A front window 5 is arranged in front of the driver's seat side front seat 2 and the passenger's seat side front seat 3, and each of the front seats 2 and 3 is arranged.
Front side windows 6a and 6b are respectively arranged on the side portions of. Further, a rear window 7 is arranged behind the rear seat 4 and the rear seat 4
Rear side windows 8a and 8b are respectively arranged on both side portions of.

In the present embodiment, as shown in FIGS. 1 to 3, the seat cushions 2a and 3a and the seat backs 2b and 3b of the front seats 2 and 3 are provided.
The surface of the seat cushion 4a of the rear seat 4 and the surface of the seat back 4b are also covered with the napped skin material 9 as the interior skin material according to the present embodiment. In the brushed skin material 9 that covers the surfaces of the seat cushion 2a and the seat back 2b of the driver's seat side front seat 2, the side portion of the front windshield 5 and the front portion of one of the front side windows 6a are formed. The nap is raised toward the front pillar portion 10a side, and the forward direction of the napped skin material 9 is mainly incident on the front pillar 10a side into the vehicle interior as indicated by the arrow in FIG. It is set toward the incident direction side of the external incident light.

Further, in the raised skin material 9 that covers the surfaces of the seat cushion 3a and the seat back 3b of the front passenger seat side front seat 3, the side portion of the front window glass 5 and the front side of the other front side window 6b are provided. Between the front pillar portion 10b and the front pillar portion 10b, and the forward direction of the napped skin material 9 is, as shown by the arrow in FIG. Is set toward the incident direction side of the external incident light that is incident on.

Further, in the raised skin material 9 covering the surfaces of the seat cushion 4a and the seat back 4b of the rear seat 4, the left and right rear side windows 8a, 8b are bordered by the central portion of the rear seat 4 in the vehicle width direction. Externally incident while being fluffed toward the side and the forward direction of the napped skin material 9 is mainly incident on the left and right rear side windows 8a, 8b into the vehicle interior as shown by the arrow in FIG. It is set toward the light incident direction side.

Here, in order to elucidate the mechanism of the white blur state on the surface of the napped skin material 9, a method of measuring the state of light reflection on the surface of the napped skin material 9 performed by the inventor of the present invention. 4, the surface of the napped skin material 9 is irradiated with the inspection light L at a predetermined incident angle, that is, at an incident angle of −45 ° with respect to the normal line Y, and the inspection light L is irradiated. Then, in the vertical plane passing through the normal line Y, the light receiving means 11 was moved in the range of 90 ° to the left and right around the normal line Y, and the distribution state of the reflectance of the inspection light L at each site was measured. As a result, when the forward direction of the napped skin material 9 shown by the arrow X in FIG. 4 and the incident direction of the inspection light L are directed in the same direction, as shown by the solid line A in FIG. The reflectance in the retroreflective direction at the time of fluffing of the napped skin material 9 is
It was confirmed that the reflectance was much higher than the reflectance when raised, which is indicated by the dotted line B. It was found that the larger the difference in reflectance in the retroreflective direction between when the hair is fluffed and when the hair is raised, the more pronounced the white blurring on the surface of the napped skin material 9.

As shown in FIG. 6, when the normal direction of the napped skin material 9 and the incident direction of the inspection light L are directed in the same direction, when the napped skin material 9 is raised. The inspection light L is specularly reflected by the tip surface of the tip of the hair, and the amount of reflection in the retroreflection direction is reduced, and as shown in FIG. 7, the normal direction of the napped skin material 9 and the incident direction of the inspection light L. In the same direction, the inspection light L is reflected in the retroreflective direction by the side surface of the napped epidermal material 9 when the napped hair 9 is fluffed, and the amount of reflection in the retroreflective direction is increased. This is because the difference in the reflectance in the retroreflective direction becomes larger.

On the other hand, in the case where the normal direction of the napped skin material 9 is opposite to the X direction with respect to the incident direction of the inspection light L shown in FIG. 4, as shown by the solid line A in FIG. While the reflectance of the napped skin material 9 in the retroreflection direction at the time of fluffing decreases, as shown by the dotted line B, the reflectance of the napped skin material 9 in the retroreflection direction at the time of napping increases, It was confirmed that the difference in reflectance in the retroreflective direction between when bristled and when raised was reduced.

As shown in FIG. 9, this is the case when the napped skin material 9 is raised when the normal direction of the napped skin material 9 is set toward the incident direction side of the inspection light L. 10, the inspection light L is reflected in the retroreflective direction by the tip surface of the bristle tip, and the amount of reflection in the retroreflective direction is increased.
As shown in FIG. 6, when the normal direction of the napped skin material 9 and the incident direction of the inspection light L are directed in the same direction, the inspection light L is positively reflected by the side surface of the napped skin material 9 when the hair is fluffed. This is because the amount of reflection in the retroreflective direction decreases due to reflection.

As described above, by stretching the napped skin material 9 so that the normal direction of the napped skin material 9 is toward the incident direction side of external incident light, the napped skin material 9 is fluffed. The difference in the amount of reflection in the retroreflective direction from that when brushed will decrease,
It is possible to prevent white blur and prevent deterioration of the high-class feeling without damaging the original color of the napped skin material 9.

In particular, according to this embodiment, the brushed skin materials 9, 9 covering the front seats 2, 3 on the driver's seat side and the passenger's seat side are close to the front seats 2, 3 respectively. Pillar portion 10 between the side portion of the front window 5 and the front portions of the left and right front side windows 6a and 6b.
Since the naps are raised toward the a and 10b sides, the pillar portions 10a and 10b are mainly formed on the surfaces of the front seats 2 and 3.
The napped skin materials 9, 9 are raised in the incident direction of the external incident light incident from the side, and the amount of reflection in the retroreflection direction during raising is increased. The difference in the amount of reflection in the retroreflective direction between when the hair is fluffed and when the hair is fluffed is suppressed, and white blurring is suppressed. Since the nap is raised toward the rear side windows 8a, 8b, the napped skin material 9 is raised on the surface of the rear seat 4 mainly in the incident direction of external incident light incident from the left and right rear side windows 8a, 8b. As a result, the amount of reflection in the retroreflective direction during raising is increased, which reduces the difference in the amount of reflection in the retroreflective direction between raising and fluffing and suppresses white blur. To be done on Never be original color of the hair raising of the skin material 9 covering the surface of the front sheet 2, 3 and the rear seat 4 is impaired to lower the luxury is prevented.

11 and 12 show the second and third embodiments of the napped skin material 9, and the napped skin material 19 of the second embodiment shown in FIG. 11 is the napped skin material. Material 19
Since the pile tips of each of the pile materials 19a constituting the above are formed into a tapered conical shape, the external incident light L irradiated on the tip of the cone is reflected in the retroreflection direction by the action of the conical surface. The amount of reflection in the retroreflective direction at the time of raising the hair is increased as compared with the case where the hair tips of the hair raising skin material 19 are flat, and thus, the recurrence at the time of raising and at the time of bending By reducing the difference in the reflection amount in the reflection direction, it is possible to prevent white blurring on the surface of the napped skin material 19 and prevent the original color of the skin material from being impaired, thereby lowering the sense of quality. Absent.

On the other hand, in the napped skin material 29 of the third embodiment shown in FIG. 12, each pile material 29a constituting the napped skin material 29 has a V-shape in which the tips of the pile materials 29a are expanded as compared with the root. Since the external incident light L applied to the expanded pile material 29a is reflected in the retroreflection direction by the side surface of each expanded pile material 29a, the napped skin material 29 is set upright. The amount of reflection in the retroreflective direction during raising is increased compared to the case of raising, and this reduces the difference in the amount of reflection in the retroreflective direction between raising and fluffing. It is possible to prevent white blurring on the surface of the sexual skin material 29 from being suppressed, and to prevent the original color of the skin material from being impaired, so that the high-class feeling is not deteriorated.

In this embodiment, the case where the surfaces of the front seats 2, 3 and the rear seat 4 are covered with the napped skin material 9 has been described, but the napped skin material 9 is not limited to the seat skin material. Not something.
