Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle instrument panel structure.

[0002]

2. Description of the Related Art As a conventional vehicle instrument panel structure, there are, for example, those shown in Japanese Utility Model Laid-Open No. 56-46438 and those shown in FIG. The instrument panel 1 of the vehicle M is formed by integrally providing a pad 2 made of polyurethane foam material and a skin member 3 made of polyvinyl chloride on the surface of a core material 2a, and an instrument is provided at a position facing the driver. The board 4 is embedded. This instrument panel 4
It consists of instruments 5 such as a speedometer and a fuel gauge, a bulb 6 for illumination, and an instrument box 7 containing these, and a glass (transparent body) 8 is provided at the front opening of the instrument box 7. Then, the light L from the outside that enters the inside of the vehicle through the front window panel 9 and the side window panel 10 is reflected by the glass 8 on the front surface (A side in the drawing) of the instrument panel 4 and the instruments 5
A hood 11 is provided above the instrument panel 4 by extending the instrument panel 1 in order to prevent the hood 11 from being hard to see. Further, the glass 8 is curved so that the reflected light of the light L from the rear does not enter the eyes of the driver.
Incidentally, 12 is a front pillar.

[0003]

However, in such a conventional technique, it is possible to prevent the light from the instrument panel 4 from being reflected on the front wind panel 9 or the like during night driving, or to prevent the front wind panel 9 from being reflected. Since the hood 11 projects toward the occupant in order to block a part of the light L incident from the side window panel 10 and the side window panel 10 to ensure the visibility, the spaciousness of the vehicle interior is impaired and the instrument is installed. It is disadvantageous because it becomes a restriction when modeling the panel 1 and the like.

The present invention was made by paying attention to such a conventional technique, and the driver can surely visually recognize the instruments without being dazzled by the light from the inside of the instrument panel or the light from the outside. And a structure of a vehicle instrument panel that gives the occupant a spacious feeling and improves the degree of freedom in shaping around the instrument panel.

[0005]

The structure of a vehicle instrument panel according to the present invention comprises an instrument panel in which an instrument panel and a light source are built-in and a transparent body is provided on the front surface. The front surface of the transparent body is integrally covered with a cloth skin member that transmits light but does not reflect light, and a stretch prevention sheet is attached to a portion of the skin member facing the transparent body.

[0006]

According to the structure of the vehicle instrument panel according to the present invention,
Since the transparent body on the front of the instrument panel is integrally covered with a cloth skin member used for the instrument panel that transmits light but does not reflect light, the light rays incident from the outside are directly Visibility can be ensured without hitting the transparent body and being reflected, and because the light from the instrument panel is not reflected on the front wind panel at the time of traveling at night and does not hinder the driver's view. For this reason, it is no longer necessary to provide a hood above the instrument panel as in the past, which increases the sense of unity and spaciousness of the instrument panel, and
The degree of freedom in the molding surface increases. Furthermore, since the stretch-preventing sheet is attached to the surface of the cloth-made skin member facing the transparent body, uneven expansion and contraction of the skin member due to the influence of temperature is prevented, and the light transmitted through the skin member becomes uniform. The visibility of the board is secured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to FIGS.
It will be explained based on. Here, parts common to those of the conventional example are denoted by the same reference numerals, and overlapping description will be omitted.

Reference numeral 20 is an instrument panel, which is provided on the front surface (side surface A in the figure) of an instrument panel 21 in the front portion of the vehicle compartment. Inside the instrument box 22 of the instrument panel 20, there are provided instruments 23 such as a speedometer, and a valve (light source) 24 for illuminating the instruments 23 from the rear at night to ensure visibility. A flat transparent resin body (transparent body) 25 is fitted on the front surface of the instrument box 22. Alphanumeric characters 26 are provided on the inner surface of the transparent resin body 25 in a color different from that of the transparent resin body 25 and the rear plate 22a of the instrument box 22. Then, the cloth member (fabric skin member) 27, which is the skin member of the instrument panel 21, is the pad 2
And covers the front surface of the transparent resin body 25. A transparent stretch prevention sheet 28 is attached to the back surface of the cloth member 27 facing the transparent resin body 25 so that the cloth member 27 does not stretch. The stretch preventing sheet 28 is positioned in front of the transparent resin body 25 with a predetermined space (including a case where the space is zero).

That is, the pad 2 expands and contracts due to thermal deformation due to the temperature change in the passenger compartment, and the cloth member 27 covering the pad 2 also expands and contracts, which causes wrinkles and local expansion. May occur greatly. Therefore, the expansion preventing sheet 28 is provided in order to prevent the cloth member 27 from expanding and contracting and maintain a certain light transmittance. This stretch prevention sheet 28
Is determined according to the elongation rate of the cloth member 27 used. For example, in the case of the cloth member 27 having a high elongation rate, even if the pad 2 is expanded by heat, the cloth member 27 in the portion corresponding to the pad 2 is sufficiently expanded following the pad 2, so that the front surface of the transparent resin body 25 is The cloth member 27 in the portion corresponding to is not affected much (is not stretched so much). Therefore, the thickness of the stretch prevention sheet 28 can be small. On the other hand, in the case of the cloth member 27 having a low elongation rate, the cloth member 27 in the portion corresponding to the pad 2 does not expand sufficiently, and the expansion amount of the pad 2 becomes larger than the expansion amount of the cloth member 27. The cloth member 27 is pulled due to the difference in the amount of expansion between the two, and as a result, the cloth member 27 in the portion corresponding to the front surface of the transparent resin body 25 also expands. Therefore, in such a case, it is necessary to increase the thickness of the stretch prevention sheet 28 in order to reliably prevent the stretch of the cloth member 27. The elongation of the cloth member 27 is caused not only by such a temperature factor but also by factors such as moisture in the vehicle compartment. The elongation-preventing sheet 28 of this embodiment surely prevents elongation of any cause.

The elongation rate of the cloth member 27 with respect to the tensile force is shown in FIG. The horizontal axis indicates the horizontal elongation rate, and the vertical axis indicates the vertical elongation rate as a percentage. In the figure, the range indicated by a is of a crimped knit, the range indicated by b is a plain weave of elastic yarn, the range indicated by c is of a knitted elastic yarn, and the range indicated by d is an intermediate orientation system of polyester. , And shows the distribution of elongation rate, respectively. It should be noted that since a tension of about 2.5 t is applied to a and b, and a tension of about 3.5 t is applied to c and d, the a and b groups and the c and d groups are simplified. Although it cannot be compared, it can be said that the elongation rate increases as going from a to d. Here, the elastic yarn is generally 35% rayon yarn and 65% polyester yarn.
A urethane-based yarn is wound around the blended yarn to make it easier to stretch. This stretchable yarn is added to the conventional blended yarn, for example, 1
The cloth member 27 that has been shrunk by being mixed at a rate of 0% has been described. In addition, crimped means a crimped wound thread. And the intermediate orientation system is generally made by pulling to align the direction of the molecules of the thread in one direction when making the thread, but it is made without pulling it so much that the molecule tends to stretch when heat is applied It has the character of trying to line up in one direction.

Reference numeral 29 is a needle for indicating speed, temperature and the like. The needle 29 is a colored transparent member, but has a color different from the color of the cloth member 27 and the rear plate 22a of the instrument box 22 from the viewpoint of visibility. And 3
0 is a vent grill.

As described above, since the front surface of the transparent resin body 25 on the front surface of the instrument panel 20 is covered with the cloth member 27, the light of the valve 24 inside the instrument panel 20 is reflected on the front window panel 9 while traveling at night, and the front view is reduced. It is possible to prevent the external light from being reflected on the front surface of the transparent resin body 25 and dazzling the driver during the daytime driving and the nighttime driving. Further, since the stretch preventing sheet 28 is attached to the portion of the cloth member 27 facing the resin transparent body 25 to prevent the cloth member 27 from stretching, uneven stretching of the cloth member due to temperature and humidity is prevented, and the cloth member 27 is prevented. The light transmitted through 27 becomes uniform and visibility can be secured. Further, this eliminates the need for providing the hood 11 around the instrument panel 4 as in the conventional case, so that the feeling of spaciousness is increased and the degree of freedom in shaping around the instrument panel 20 is increased.

In the above embodiment, the stretch prevention sheet 28 attached to the cloth member 27 is located in front of the transparent resin body 25. However, as shown in FIG.
The stretch prevention sheet 28 may be attached to the front surface of the transparent resin body 25 with an adhesive. In this case, it should be noted that the thickness of the stretch-preventing sheet 28 is increased in consideration of the influence of expansion and contraction of the transparent resin body 25. The other structure is the same as that of the above-mentioned embodiment, and the same effect can be obtained. Further, although the example in which the bulb 24 is provided as a light source separately from the instruments 23 is described in the above embodiment, the invention may be applied to a so-called electronic meter in which the instruments 23 themselves emit light.

[0014]

As described above, in the structure of the vehicle instrument panel according to the present invention, the transparent body on the instrument panel front surface is integrally covered with the cloth skin member used for the instrument panel. Light rays incident from the outside do not directly hit the transparent body and are not reflected, and the light from the instrument panel is not reflected on the front wind panel during nighttime driving, which does not hinder the driver's view. Also, there is no need to provide a hood above the instrument panel as in the past,
In addition to increasing the sense of unity and spaciousness of the instrument panel, it also increases the degree of freedom in terms of modeling. Furthermore, since the stretch-preventing sheet is attached to the portion of the fabric skin member facing the transparent body, uneven stretching of the fabric skin member due to the influence of temperature is prevented, and the light transmitted through the skin member becomes uniform. The visibility of the instrument panel is secured.
