Abstract

PROBLEM TO BE SOLVED: To increase hardness and to improve side supportability by biting skin into many closed small recesses disposed in a side support section and adhering the skin, thereby forming recessed parts for decoration. SOLUTION: A pad 2 is constituted by simultaneously expansion molding the many small recesses 10 and hollow grooves 11 and 12 in the built-up side support section 15 as well as hollow grooves 13 for forming hollow grooves for ornamentation on a front part side at the time of molding. The many small recesses 10 are, therefore, integrally foamed in the side support section 15 of a pad 1. The adhesive is sufficiently adhered into the respective small recesses 10, the hollow grooves 11 and 12 and the hollow grooves 13 to form the cured layers of the adhesive in such a manner that the skin 2 is bitten and adhered into the respective small recesses 10, the hollow grooves 11 and 12 and the hollow grooves 13. Since the seat is constituted by forming such recessed parts for ornamentation, the side support of the seat is made rigid and the side supportability is improved. In addition, there is no odd feel at the time of use and a comfortable feel to seat is obtained. Since the pad may be formed with one kind of foams, the moldability is improved as well.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a surface (seating surface) structure of a vehicle seat such as an automobile seat.

[0002]

2. Description of the Related Art Some automotive seats are provided with raised side support portions on the left and right sides of a seat cushion and a seat back in order to improve the holdability of a seated person.

[0003] The adhesive sheet having the side support portion is formed by bonding a skin to a molded foam pad.

In some cases, the pad corresponding to the side support portion is formed of a high-density or hard foam at a central portion in order to improve the side support properties.

[0005]

In the above-mentioned pad, the portion corresponding to the side support portion is formed of a high-density, hard foam, and is formed of at least two types of foam pads. In addition to poor moldability, the center portion of the pad and the side support portion have different elasticity and the like, so that there is a problem in that a foreign-body sensation occurs during use.

On the other hand, when the entire pad is formed of the same foam, the above-mentioned problem is solved, but the side support is deteriorated, and the side support has a problem that the sheet is fattered by long-term use of the sheet.

Therefore, an object of the present invention is to eliminate such disadvantages of the conventional product.

[0008]

According to the present invention, there is provided a foam pad having raised side support portions on the left and right sides of a surface, which is formed by covering and bonding a skin. In the vehicle seat, a large number of independent small recesses are provided in the side support formation portion of the pad, and the skin is bitten into and bonded to each of the small recesses,
This is a configuration in which a large number of decorative concave portions are provided in the side support portions of the seat.

Therefore, the decorative concave portion formed by biting the skin into a large number of independent small concave recesses provided on the pad and bonding the hardened portion is hardened by hardening of the adhesive, biting of the skin, and the like. The performance is improved.

In addition, since each small concave is formed by foaming with a mold at the same time as pad foam molding, a hardened layer is formed in each small concave portion, so that the side support properties are further improved, and The cured layer also improves the adhesion of the skin.

In addition, since the decorative concave portion is formed in the shape of a circular plane, the appearance quality of the sheet is also improved.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a seat cushion (SC) of an automobile seat according to the present invention.
Indicates a circular decorative recess formed in the raised side support portions (9) on the left and right sides of the seating surface.

The large number of decorative concave portions (4) are disposed in decorative annular concave grooves (5) and (6) formed around the side support portions (9) and (9) to improve the appearance quality of the sheet. Have improved.

A central portion (8) between the left and right side support portions (9) is substantially flat and has a side support portion (9).
It is formed lower than (9). (7) in the figure shows a decorative groove formed on the front side of the seating surface of the seat cushion (SC).

As shown in FIG. 2, the decorative concave portion (4) has a skin (2) in a small concave portion (10) provided in a foam pad (1) supported by a frame (3). ) Is formed by biting and bonding with an adhesive.

As shown in the figure, the annular groove (5)
(6) also the concave grooves (11) and (12) provided in the pad (1)
It is formed by biting the skin (2) into the inside and bonding with an adhesive.

Therefore, the side support portions (9) (9)
Is hardened with respect to the central portion (8) by the annular concave grooves (5) and (6) and a large number of decorative concave portions (4) provided therein, and side support properties are improved.

FIG. 3 shows a state before the skin (2) is bonded to the pad (1). The pad (2) is molded into a substantially outer shape of the seat cushion (SC), and a bump-like shape is formed during the molding. A large number of small concaves (10) and concave grooves (11) and (12) are formed in the side support forming part (15), and a concave groove (13) for forming a decorative groove (7) is formed on the front side. Foam molding is performed simultaneously on the surface.

Therefore, a large number of small concave portions (10) are integrally foamed in the side support forming portion (15) of the pad (1). Accordingly, the center (1) of the seating surface of the pad (1)
Compared with 4), the impregnated hardened layer per unit area is formed to be large, and especially in the small recessed recess (10), the hardened layer on the side wall of the recess almost coincides with the load direction applied to the side support formation portion of the pad. And the side support is improved.

As shown in FIG. 4, the pad (1) is placed on a pan-shaped frame (3) or foamed integrally with the frame (3) and sewed in a bag shape in advance. The skin (2) is covered and adhered with an adhesive.

The above-mentioned skin (2) is formed by each of the small concaves (10),
Each of the small recesses (10) and the concave grooves (11) so that they are bitten into the concave grooves (11) and (12) and the concave grooves (13) and are bonded.
(12) An adhesive is sufficiently adhered in the groove (13) so that a cured layer of the adhesive is formed.

The amount of adhesive applied (per unit area)
The left and right side support forming portions (15)
It is preferable that a hardened layer by an adhesive is formed on the side support (9) of the seat cushion (SC) in comparison with 4).

[0023]

According to the present invention, a decorative concave portion is formed by making the outer skin bite and adhere to a number of independent small concave portions provided in the side support forming portion of the pad. Becomes hard, the side support properties are improved, and a comfortable sitting feeling is obtained without any discomfort during use.

Further, since the pad can be formed with one kind of foam, the formability is also improved.

According to the second aspect of the present invention, since each small concave portion of the pad is foam-formed by a mold at the same time when the pad is formed, an impregnated layer of a foaming liquid is formed along each small concave portion,
Further, the side support property is improved, and the adhesion of the skin to each small concave is also improved. Therefore, the side support property is further improved by the cured layer of the adhesive.

According to the third aspect of the present invention, since the decorative concave portion is formed in the side support portion of the sheet, the appearance quality of the sheet can be improved.
