Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat cover with a side support function that can firmly hold the lumbar region and the flank region of a seated person and is excellent in appearance quality.

[0002]

2. Description of the Related Art For example, in automobile seats,
When sitting for a long time, the waist and flanks become tired, so it is known to have a side support function. As a seat that exerts this side support function, it is common to use a pad body that constitutes a seat back with support ridges formed on both side parts, but in this case it is intended for all physiques As it is designed to fit an average physique, there is a problem in that it does not surely fit the waist and flanks of the seated person and cannot exert a sufficient side support function effect.

On the other hand, in order to solve such problems,
A support type ridge on both sides has been developed that can be adjusted by an adjustment mechanism. In this case, however, it is necessary to embed the ridge adjustment mechanism inside the seatback. However, there is a problem in that it becomes complicated and heavy in weight, and further in cost.

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned conventional problems and can reliably support the lumbar region and the flank region even for a seated person of any body type, and has a structure. The purpose of the present invention is to provide a seat cover with a side support function, which is simple and can contribute to weight reduction and productivity, and can significantly reduce the cost.

[0005]

The seat cover of the present invention, which has been made to solve the above problems, has auxiliary pads for side support attached to the inner surfaces of both side parts of the front part of the cover body for covering the seat back. It is characterized by being present.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described below with reference to the drawings. The drawings show the case in which the present invention is applied to a vehicle seat, and in the drawing, reference numeral 1 is a cover body that covers a seat back 10. The seat back 10 described above is a standard one designed to fit an average physique.
The cover body 1 for covering 0 is provided with the auxiliary pads 2 for side supports, which are made of a synthetic resin material having elasticity such as urethane foam, exchangeably attached to the inner surfaces of both side portions of the front surface 1a. That is, the auxiliary pads 2 for the side support are prepared in various sizes, and any one can be selected according to the body shape of the seated person. It surely fits the waist and flanks, and provides a sufficient side support effect.

More specifically, a bag portion 3 for accommodating auxiliary pads is provided on the inner surface of both side portions of the front surface portion 1a of the cover body 1, and the bag portion 3 is selected according to the physique. The auxiliary pad 2 for an arbitrary side support is stored. That is, the bag portion 3 is cut so that it conforms to the outer shape of the side portion of the seat back 10, and the front surface portion that is trimmed so as to conform to the outer shape of the surface portion of the auxiliary pad 2 for side support. 3b is sewn into a bag shape, leaving an opening for taking in and out the auxiliary pad, and the pad 2 is configured to be closely and firmly fixed to the side portion of the seat back 10. As shown in FIG. 3, if the cover main body 1 is formed by laminating a skin material 11 having excellent stretchability and a urethane foam sheet 12 having cushioning properties, it can be assisted in the bag portion 3. It is more preferable because the pad 2 is tightly wrapped and a proper cushioning property of the surface can be secured.

Further, a fixing means 4 for the cover body 1 is provided below the cover body 1. In the first embodiment shown in FIG. 4, the cover fixing means 4 includes a cover fixing pipe 5 which is inserted through an elastic cord 6 which is stretched laterally in a lower portion on the back side of the cover body 1 and a cover. It is composed of a fixed sheet piece 7 with a surface fastener 7a hanging from the lower end on the front surface side of the main body 1, and the fixed sheet piece 7 is folded back to the cover fixing pipe 5 and is locked and fixed by the surface fastener 7. However, as in the second embodiment shown in FIG. 5, elastic band members 8 provided on both lower sides of the back side of the cover body 1 are locked to both sides of the lower end of the seat back 10. There is no particular limitation on what is fixed, and the cover body 1 can be easily attached to the seat back 10 with one touch.
Anything can be used as long as it can fit exactly to 0. Further, as in the third embodiment shown in FIG. 4, the cover fixing means 4 is hung at the lower end on the front surface side of the cover body 1 and has a bag-sewn portion 7b formed at the tip thereof. The cover fixing pipe 5 is inserted into the inside 7b, and the bag sewn portion 7b is press-fitted and fixed between the lower end surface of the seat back 10 and the rear end upper surface of the seat cushion 10a. You can also

With such a structure, the auxiliary pads 2 for side support are attached to the inner surfaces of both side portions of the front surface portion 1a of the cover body 1 for covering the seat back 10, so that the pad of the seat back 10 becomes a side support portion. Even if it is a normal one, both side portions of the seat back 10 are raised by the auxiliary pad 2 as raised portions for support, and these portions are laid through the front face portion 1a of the cover body 1 to the waist and flanks of the seated person. It is possible to reliably support and maintain a stable posture, and therefore it is difficult for the user to feel fatigue even when sitting for a long time. Also, the auxiliary pad 2 for the side support can be selected to have an optimum size according to one's body shape, so that the side support function can be surely fitted and a satisfactory side support function effect can be obtained. Furthermore, since the auxiliary pad 2 for side support is inside the cover body 1 and is not visible to the outside, the appearance is also excellent.

[0010]

As is apparent from the above description, the present invention has the auxiliary pads for side supports attached to the inner surfaces of both side portions of the front portion of the cover body that covers the seat back, so that seated persons of all body types can be accommodated. In addition to being able to reliably support the lumbar region and the flank region, it is possible for the structure of the seatback pad to have a simple structure and to contribute greatly to weight reduction and productivity, as the side support part does not have to be formed. In addition, the cost can be significantly reduced. Therefore, the present invention, as a seat cover that eliminates the conventional problems, contributes greatly to industrial development.
