Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to automobile interior parts such as armrests, console lids, glove doors, and the like, and more specifically, injection molding of polyvinyl chloride resin, ABS resin, etc., metal Injection molding on the surface of insert molded by press molding,
The present invention relates to an automobile interior product having a skin formed separately by vacuum forming, slush forming, rotation forming blow forming, or the like, which is characterized by a joint structure between the skin and the insert.

(Prior Art) For example, an automobile armrest is used as an armrest of a driver or an occupant, or as a pull handle when opening and closing a door, and is widely mounted in passenger cars, commercial vehicles and other automobiles. The structure of the armrest depends on the purpose of the car,
Various types have been proposed according to the application, but as a relatively simple structure and sturdy, it is necessary to use a separately molded skin directly on the insert molded by injection molding or press molding, or if necessary. Correspondingly, a material attached via a cushion material is widely used.

Further, conventionally, as a method of joining the insert of the armrest and the epidermis, a means for adhering the both with an adhesive or a double-sided adhesive tape between them has been used.

(Problems to be solved by the invention) Although automobile interior parts such as armrests of the related art have good characteristics immediately after manufacturing, they are apt to lose their shape over time and are improved in this respect. It had a problem to be done.

In other words, it is not uncommon for the interior temperature of an automobile to rise to around 80 ° C in the summer, and to drop below freezing in the winter.

When conventional automotive interior parts are exposed to such a wide range of temperature changes, the difference in expansion and contraction rate due to the difference in the materials of the skin and insert, and the expansion due to the difference in the wall thickness and curvature of each part Adhesion of the epidermis may be peeled off due to the difference in contraction rate, and this problem frequently occurs especially in the structure in which the epidermis is attached with a cushioning material partially interposed.

In order to solve this problem, improvements have been made to the adhesive and double-sided tape, and the flexibility of the adhesive itself has been improved so that the adhesive can follow the shape change of the epidermis and prevent peeling of the epidermis. However, even with this method, it is unavoidable that swelling and wrinkling occur at various parts of the epidermis, particularly at the corners of the concave part of the epidermis.

Therefore, the present invention focuses on the drawbacks of the prior art, and proposes an automobile interior product capable of preventing peeling of the skin and the insert and generation of wrinkles on the surface and maintaining good appearance for a long period of time.

(Means for Solving the Problems) Therefore, the feature of the present invention for achieving the above-mentioned object is that the insert has a slit in the automobile interior part in which the surface of the insert is covered with a separately molded skin. And, a protrusion is provided in the vicinity of the slit on the back surface of the insert, and the epidermis has a tongue-like portion at a position corresponding to the slit, and the tongue-like portion is provided with B, and the tongue-like portion of the epidermis is There is an automobile interior product in which a skin is attached to an insert in a state in which a surface of the insert is inserted into a slit, and a protrusion of a back surface has a hole of a textured portion. When automobile interior parts are placed in a high temperature or in a low temperature atmosphere, each part of the epidermis tends to move from its original position, and each part tends to swell or wrinkle.

However, since the tongue-shaped portion of the armrest of the present invention has the tongue-shaped portion locked to the protrusion of the automobile interior parts and strongly pulled from the back side, the movement is suppressed, and the bulge generated at each portion disappears by being pulled to the tongue-shaped portion. To do.

(Example) Hereinafter, a specific example of the present invention will be described.

1 is a sectional view of an armrest according to a specific embodiment of the present invention, and FIG. 2 is a view in the direction of arrow A in FIG.

In FIG. 1, (1) shows an armrest in a concrete embodiment of the present invention. The armrest of this embodiment is attached to an automobile door trim (not shown), and has an outer shape having a recessed portion (3) used as a pull handle in addition to an upper surface portion (2) that functions as an armrest.

Then, the inner structure has a skin (5) which is separately molded by injection molding, vacuum molding, blow molding, slush molding or the like on the surface of a synthetic resin or metal insert (4) molded by injection molding, press molding or the like. In particular, the cushioning material (6) made of polyethylene, polystyrene, urethane, pulp, or a recycled material of these, which is formed separately, is embedded only around the upper surface portion on which the occupant's elbows and arms come into contact.

Then, when the skin (5) is attached to the insert (4), the folded-back portions (7) and (8) are provided at the end portions of the skin and the folded-back portions (7) and (8) are fitted with the end portions of the insert (4). Although it is made by penetrating, the following configurations should be noted in the embodiment of the present invention.

That is, the insert of the present embodiment has slits (9) at the corners of the recess (3), and the vicinity of the slit (9) side on the back surface of the insert overhangs (10) in an extended manner with respect to the slit (9).
Is provided, and a projection (20) is provided at the tip of the overhang (10).

Further, the slit (9) is provided with a notch (11) on the surface facing the overhang (10).

On the other hand, the skin (5) is similar to the insert (4) in the recess (3).
A tongue (12) is formed on the back surface of the corner of the. This tongue (12) is roughly the same thickness as the epidermis (5).
It is about 5 to 2 mm and the tip is thinned and the hole (13)
Is provided. The tongue (12) has an upper hole (13) inserted into the slit (9) of the insert (4) from the front side and locked by being inserted into the protrusion (20).

In the configuration of the present embodiment, the position where the tongue-like portion (12) is provided is arbitrary, and the more the tongue-like portion (12) is provided, the greater the effect. Since it is easy to do so, the maximum effect can be achieved with the minimum number of attachments when it is provided in that part.

Further, the length of the tongue-shaped portion (12) and the protruding portion (10) absorbs the deformation of the epidermis (5) by the elasticity of the tongue-shaped portion (12), and it is preferable that the length is as long as possible. Position of the hole (13) provided in the tongue (12) and the protruding portion (10)
The length relationship between the two may be equal at room temperature, but if the overhang (10) is made slightly longer, the initial tension of the tongue (12) will be applied and the sense of unity with the insert will increase. Is obtained and is preferable.

Specifically, it is most preferable to set the overhang portion of about 5 to 20% to be long. Further, the relationship between the width of the slit (9) and the thickness of the tongue (12) is that the tongue (12) absorbs the deformation of the epidermis due to the expansion and contraction of the tongue (12) so that the tongue (12) moves within the slit (9). It is desirable to set it so that it can move, and it is also effective to provide the notch (11) as in this embodiment.

However, on the other hand, depending on the material of the epidermis, the slit is set to be narrower than the thickness of the tongue, and the tongue can be engaged with the slit to assist in locking the epidermis.
In this structure, it is also effective to provide a large number of notches in the slit and improve the elasticity of the slit to further improve the fitting of the two.

Further, it is preferable to set the tip of the tongue (12) thin as in the present embodiment because it has an effect of facilitating the assembling.
The armrest of the present invention can sufficiently maintain its shape without interposing an adhesive or the like between the outer skin and the insert, but when used together with the adhesive, a greater effect can be obtained. Needless to say. Although the armrest is taken as an example in the present embodiment, the same structural plasticity can be adopted for other automobile interior parts.

(Effect) The automobile interior part of the present invention has a tongue-shaped portion on the surface of the skin, and the tongue-shaped portion is inserted into the slit of the insert, and by adopting a structure in which it is locked to the back side of the insert by a hole, The tongue portion absorbs the deformation of the skin and the insert, especially the deformation due to heat, and has the effect of preventing the surface from swelling or peeling.

In addition, there is an effect that the step of applying an adhesive or the like to the insert, which has been essential in the past, can be omitted, which also contributes to improvement in workability and productivity.
