Description

Interior panel for vehicle and method for manufacturing interior panel for vehicle

The present invention relates to an interior panel for a vehicle such as an instrument panel and a manufacturing method thereof.

Interior panels such as instrument panels and door trims are installed in the car interior. For example, Patent Document 1 discloses such an interior panel and a manufacturing method thereof.

A conventional interior panel is composed of a base material molded into a predetermined shape and a skin member adhered to the surface of the base material.

The base material is made of, for example, polypropylene resin. The skin member is made of, for example, polyvinyl chloride resin.

When manufacturing such an interior panel, first, the base material is formed by injection molding. And the raw fabric sheet | seat which is the raw material of the said skin member is heated and softened, and is affixed with respect to the surface of a base material. A raw sheet having a uniform thickness as a whole is used.

JP-A-10-156866

The following problems may occur in the interior panel and the manufacturing method thereof described above. For example, as shown in FIG. 19, when manufacturing an instrument panel having a meter hood 102 having a bent portion 104, a skin member 120 is attached to the surface of a base material 110. The attached skin member 120 is stretched at the bent portion 104 more than other portions. Thereby, the cushioning property of the skin member 120 is impaired at the bent portion 104 of the meter hood 102. Therefore, when the occupant pushes the bent portion 104, the bent portion 104 reaches the compression limit earlier than other portions, and the tactile sensation is impaired.

In contrast, it is conceivable to use a thick skin member. However, in this case, since the skin member is thickened more than necessary to the part that the occupant hardly touches, the weight of the interior panel may increase.

An object of the present invention is to provide an interior panel for a vehicle that can suppress an increase in the weight of the interior panel while suitably improving the feel of the interior panel. Moreover, it is providing the manufacturing method of the interior panel for vehicles which can manufacture easily the interior panel which improved the tactile sense.

In order to achieve the above object, an interior panel for a vehicle according to the present invention has a base material, a laminated skin layer and a cushion layer, and is attached to the surface of the base material with the skin layer on the outside. A member. An intermediate member having a cushion layer is interposed between a part of the base material and the skin member.

According to this configuration, the cushion layer at the portion where the intermediate member is interposed in the interior panel becomes thick. For this reason, the cushion layer of the interior panel can be partially thickened. Therefore, an increase in the weight of the interior panel can be suppressed while suitably improving the tactile sensation of a specific portion of the interior panel.

It is preferable that a recess for accommodating at least the end of the intermediate member is formed on the surface of the base material.

In this case, since the end of the intermediate member enters the recess formed on the surface of the base material, the step formed on the surface of the skin member at the end of the intermediate member can be reduced. Therefore, it can suppress suitably that the designability and tactile sense of an interior panel are impaired.

Further, it is preferable that the intermediate member is housed in the recess so that the surface of the base material and the surface of the intermediate member are flush with each other.

In this case, since the base material and the intermediate member are flush with each other by the recess, no step is formed on the surface of the skin member by the end of the intermediate member. Therefore, it can avoid that the designability and tactile sense of an interior panel are impaired.

An end portion of the intermediate member housed in the recess has a pointed cross-sectional shape, and the back surface of the intermediate member at the end portion gradually approaches the surface of the intermediate member as it approaches the tip of the end portion. And the base member includes a first part in which the concave part is formed and a second part in which the concave part is not formed, and the surface of the second part and the bottom surface of the concave part. It is preferable that an inclined surface is formed between and the surface of the second part is connected to the bottom surface of the recess by the inclined surface.

Further, the base material includes a first part in which the concave part is formed and a second part in which the concave part is not formed, and a stepped part is formed in the base material at a boundary between the second part and the concave part. In addition, it is preferable that the thickness of the first portion of the base material increases as the distance from the stepped portion increases.

For example, it is conceivable that a concave portion is formed over the entire portion where the intermediate member is provided on the surface of the base material, and a thin portion that is uniformly thinned is formed at the position of the concave portion in the base material. However, in this case, the rigidity of the substrate may be insufficient depending on the thickness of the thin portion.

In this regard, as described above, if the thickness of the first portion where the concave portion is formed in the base material increases as the distance from the step portion increases, the portion of the base member where the intermediate member is provided Compared to a configuration having a thin portion that is uniformly thinned as a whole, the thin portion can be reduced. Therefore, it can suppress suitably that the designability and tactile sense of an interior panel are impaired, and it can suppress suitably that the rigidity of a base material falls.

It is preferable that the interior panel includes a bent portion, and the intermediate member is provided at least in the bent portion of the interior panel.

In this case, at least the cushion layer of the bent portion of the interior panel can be thickened, and the tactile sensation can be suitably improved.

Moreover, it is preferable that the interior panel has a portion facing the vehicle seat and provided with the intermediate member.

In this case, since the intermediate member is provided at the portion of the interior panel that faces the vehicle seat, the portion that is easily touched by the occupant is thickened, and the tactile sensation of the portion can be improved suitably. On the other hand, the portion of the interior panel that is difficult for an occupant to touch is not thickened. Therefore, it is possible to suppress an increase in the weight of the interior panel while suitably improving the tactile sensation of the portion that is easily touched by the occupant in the interior panel.

The intermediate member is preferably made of the same material as the skin member.

In this case, since the intermediate member is made of the same material as the skin member, the number of types of necessary materials can be reduced compared to a configuration in which the intermediate member is made of a material different from that of the skin member, and the interior panel has a simple configuration. Can be formed.

Further, it is preferable that the portion where the intermediate member is interposed on the surface of the base material has a larger coefficient of friction than the remaining portion.

In this case, when manufacturing the interior panel, the intermediate member placed on the surface of the base material is less likely to be displaced, and part of the intermediate member is suppressed from floating from the surface of the base material. Therefore, it can suppress that a part of skin member floats or a wrinkle is formed on the surface of a skin member.

Moreover, it is preferable that the surface of the base material is subjected to a graining process on the portion where the intermediate member is interposed.

In order to achieve the above object, a method for manufacturing an interior panel for a vehicle according to the present invention includes a first step of placing an intermediate member having a cushion layer on a part of the surface of a substrate, and a laminated skin It is the 2nd process of sticking the skin member which has a layer and a cushion layer on the surface of the above-mentioned substrate, and the above-mentioned skin member is stuck so that the above-mentioned skin layer may be outside and the above-mentioned intermediate member may be covered 2 steps.

According to the method, prior to the step of attaching the skin member to the surface of the base material, the cushion member is partially formed by placing the intermediate member having the cushion layer on a part of the surface of the base material. A thickened interior panel is formed. Therefore, it is possible to easily manufacture an interior panel in which the cushion layer is suitably thickened and the tactile sensation is improved.
