Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a seat cushion structure for an automobile seat, and more specifically, to an improvement of a seat cushion structure for giving a side volume of the seat cushion a volume feeling. .

(Prior Art and its Problems) FIGS. 4 and 5 show a conventional seat cushion structure for an automobile seat. In such a conventional product, in order to give the side surface of the seat cushion a voluminous feel and to improve the external shape, the foam pad member (1 ') extends from the seating surface (2') to the side surface (3 '). Urethane material (4 ') for shaping
Is attached to the foam pad member (1 '), and the upper portion of the side surface of the seat cushion is formed so as to bulge outward (FIG. 4).

Further, the side surface portion (6 ') of the skin member (5') covering the foam pad member (1 ') is hung toward the inside of the foam pad member (1'), and as described above. The side surface of the seat cushion gives a sense of volume (Fig. 5).

Such a conventional product has the shape of the side surface portion of the seat cushion, and therefore the shape forming urethane member (4 ') is attached or the skin member (5') is hung, but the side surface portion of the seat cushion is required. It is difficult to produce a shape having a curved shape, and since the shape-forming urethane member (4 ') and the like are used, the economy is poor.

In view of the above problems, it is an object of the present invention to provide an economical seat cushion structure for an automobile seat, which allows the side surface portion of the seat cushion to have the required shape.

(Means for Solving the Problems) In order to achieve the above object, a seat cushion structure for an automobile seat according to the present invention has the above-mentioned structure between a side surface portion of a foam pad material and a side surface portion of a skin member. A plate member is provided so that a side surface portion of the skin member is curved outward, and both ends of an upper skin and a lower skin constituting the skin member are integrally sewn to a lower end of the plate member.

According to such a seat cushion structure, the side surface of the skin member is curved outward by the plate member, a volume feeling is generated in the side surface portion of the seat cushion, and the plate member is fixed to the skin member to form an upper portion forming the skin member. Since both ends of the outer skin and the lower skin are sewn to the plate member, the connecting points of both ends are linear.

(Embodiment) An embodiment according to the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 is a seat cushion for an automobile seat using a seat cushion structure according to the present invention. This seat cushion (1) is made by tensioning a spring support member (3) between a frame (2) and the spring cushion. The foam pad material (4) is placed on the support material (3), and the foam pad material (4) is covered with a skin member (5).

The skin member (5) is composed of an upper skin (51) covering the upper surface and the upper side surface of the pad material (4) and a lower skin (52) covering the lower side surface of the pad material (4) as in the conventional product. The upper skin (51) and the lower skin (52) are joined together at the side surface of the pad material (4).

Then, between the side surface portion (4a) of the foam pad material (4) and the side surface portion (5a) of the upper skin (51), the side surface portion (5a) of the skin member (5) is directed outward. A plate material (6) that bulges in a curved shape is provided.

The plate material (6) is made of a synthetic resin material and is provided along the front surface and the left and right side surfaces of the seat cushion (1).

As shown in FIG. 3, the plate material (6) is curved between the upper and lower sides to form an arcuate portion (6a), and a long hole (6b) is formed in the vertical direction.
Is provided.

The long holes (6b) of the plate member (6) are provided at equal intervals in the longitudinal direction of the plate member (6), and when the plate member (6) is placed along the side surface of the seat cushion (1), This is for facilitating bending of the plate member (6).

That is, when the plate member (6) is bent from the front surface of the seat cushion (1) to the left and right side surfaces, the long hole (6b) is formed.
This plate member (6) is for bending along the shape of the seat cushion (1) from the side surface to the front surface of the seat cushion (1).

The lower end (6c) of the plate member (6) is integrally sewn to the end portions of the upper skin (51) and the lower skin (52), which are joined to each other. Therefore, the plate member (6) is fixed to the inside of the skin member (5).

The skin member (5) to which the plate member (6) is attached is covered with the foam pad material (4), and then the lower skin (52).
Attach the end (5b) to the frame (2) with a hog ring. In the figure, (a) shows a portion where the upper skin (51) and the lower skin (52) are joined.

The seat cushion (1) is curved outward from the left and right side surfaces and the front surface by the plate member (6) attached to the skin member (5), and the side surfaces can be shaped to give a volume feeling, so that the appearance is good. Turn into.

Further, since the plate member (6) is formed with the long hole (6b) to facilitate bending of the plate member (6), the plate member (6) is seated from the side surface to the front surface of the seat cushion (1). Since it can be arranged in the shape of the cushion (1), the corner portion of the seat cushion (1) can be surely shaped.

(Effect of the Invention) According to the present invention, the following effects are obtained.

Between the foam pad material and the skin member, a plate member for forming the side surface of the skin member outward in a bow shape is provided, so that the side and front surfaces of the seat cushion have a feeling of volume, and the appearance quality. Is improved.

By providing the plate member inside the skin member,
Since it has a voluminous feel, it is economical because it is not necessary to use urethane or the like for shaping as in the past.

Since the shape is formed by the plate member,
The shape of the side and front of the seat cushion does not collapse and the volume feeling can be maintained for a long period of time.

Since the plate member is sewn to the skin member, the plate member is fixed at a predetermined position on the skin member, and the pad material is deformed due to long-term use of the seat cushion, but the pad material is not deformed, so that the plate member is not deformed. Is always in place on the seat cushion.

Also, since both ends of the upper and lower skins are sewn directly to the plate member, even if the pad material is deformed due to long-term use of the seat cushion, the joints between the upper and lower skin ends do not meander. The straightness is maintained, and the appearance quality of the seat cushion is not impaired. Further, since the plate member can be sewn on the skin member in advance, the plate member can be easily fixed, and the plate member integrated with the skin member serves as a position when the pad member is covered with the skin member, The work of covering the pad material of the member can be performed accurately and easily.
