Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a seat, in particular, the surface of the seat is formed of woven or knitted fabric into a shape that follows the surface shape of the seat body, and the interior is bonded to urethane or other cushion material. relates to an integrally molded seat filled with

BACKGROUND OF THE INVENTION Conventional molded seats have been made using only one skin, or one type of skin. Such conventional one-piece seats do not accommodate localized differences in seating elongation requirements. For example, the epidermis of the bucket part is usually stretched more than that of the seated part. In particular, when the bucket seat part is molded into one piece up to the side surface (gusset part) of the seat, the skin of the bucket seat part is further stretched. Therefore, the current situation is that the same skin that satisfies the highly stretched areas is also used for the less stretched areas.
On the other hand, depending on the specifications, the bucket part may stretch less, the seating part may have unevenness, and the outer skin may be stretched more than the bucket part. Generally, the more elongated the epidermis, the higher the price. In addition, the epidermis, which stretches a lot like this, can often develop wrinkles and sagging.

Furthermore, if it is necessary to change the color of the skin on the seat, bucket, or even side surfaces due to design requirements, it is possible to mold After that, the degree of elongation differs locally, so it is very difficult to get the border lines of different colors at the required positions after molding, and the design cannot be satisfied.

Further, in conventional molded seats, the seating portion is required to have grooves or concave and convex portions in the design. This shape heats the epidermis and compresses it using an upper mold and a lower mold. Therefore, when changing this shape, the upper mold for skin molding and cushion molding,
The lower mold must be changed, which increases costs and requires a lot of time to manufacture the mold.

Means for Solving the Problems The present invention aims to solve the above-mentioned drawbacks of the prior art. The ends are joined and individually adhered to each other within the concave groove of the cushion body.

It is preferable to use skin pieces with good elasticity for areas where elasticity is required, such as the bucket part of the seesaw, and use skin pieces with less elasticity for areas such as the seating area.

Therefore, the skin has partially different elasticity, and when sitting, one skin piece does not pull the other skin piece.

An embodiment of the present invention will be described below based on the drawings.

In the figure, reference numeral 4 denotes a seating portion of a seat body (seat cushion), and raised bucket portions 4a, 4a are provided on the left and right sides of this seating portion 4. 2 in the figure shows a side view of the seat body.

The cushion material 5 made of a molded product such as urethane foam that constitutes the seat body shown in the figure has a plurality of grooves on the seating side of the seat body, and the surface between the grooves is made of urethane foam or the like. Slab materials 6 are bonded together with adhesive.

The skin 1 to which the cushion material 5 and the slab material 6 are covered and adhered is composed of a plurality of independent skin pieces 1a, 1b, _1b2 cut into predetermined shapes, and has a seating area 1a shown in the figure. In contrast to the skin pieces, the bucket skin pieces shown as 1b and 1b in the figure are made of a highly elastic material, knitted, or woven.

Further, the portion of the skin 1 that constitutes the gusset is formed integrally with the bucket skin piece 1b.

Each skin piece 1a... is individually adhered to the cushion material 5, and the ends of the bucket part skin piece 1b and the seating part skin piece 1a are joined in the groove of the cushion material 5. Clothes, etc. are not combined as one body.

The above seating part skin piece 1a and bucket part skin piece 1
It is optional to use a different color from b, and by using such a skin piece, it is possible to provide a seat body with an excellent design.

Effects According to the present invention, since the plurality of skin pieces adhered to the surface of the cushion material are each independent, one skin piece is not affected by other skin pieces when sitting, before and after sitting. . That is, since one skin piece is not pulled by the other skin piece, the other skin piece and the cushion material to which this skin piece is adhered will not be deformed. Further, since the elasticity of one skin piece is not impaired by the other skin piece, the elasticity of one skin piece can be obtained as desired.

In addition, since a skin having the necessary elasticity can be used in the necessary locations on the seat body, wrinkles and sagging can be completely prevented.
