Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat cover for covering a seat of a vehicle or the like, and more particularly, to a backing cloth which is laminated and adhered to a seat cover pad of the seat cover.

[0002]

2. Description of the Related Art Conventionally, a seat cover 1 for covering a cushion pad attached to a seat frame of a vehicle or the like of this type has a fabric as shown in FIG.
A skin material 2 made of vinyl chloride leather or the like, and a cover pad 3 made of a urethane foam slab adhered to the skin material 2.
And a back base cloth 4 made of a non-woven fabric that is adhered to the cover pad 3.

[0003]

However, in the conventional seat cover structure, the skin material 2 and the cover pad 3 are stretchable fabrics, PVC leather and urethane foam slabs, whereas the backing fabric 4 is made of fibers. Since it is a non-woven fabric that is made into an aggregate without being made into a thread, and the fibers are adhered to each other and compressed into a thin cloth shape, it lacks elasticity and therefore external force acts to cause the skin material 2 and the cover pad 3 to elastically deform into a curved shape. The backing cloth 4 cannot follow this, and as a result, as shown in FIG. 8 (b), there is a problem that creases 5 are generated on the side of the skin material 2 and the appearance is deteriorated. The present invention has been made to solve the above-mentioned conventional problems, and a seat cover pad that can follow the expansion and contraction of the skin material and the cover pad and can prevent the occurrence of creases in the skin material. It is intended to provide a backing cloth.

[0004]

In order to solve the above technical problems, the present invention provides a seat cover comprising a cover material for covering a seat cushion, a cover pad, and a back base material, wherein the back base cloth is provided. In this configuration, elongated opening / closing means are arranged in a zigzag pattern in which they are 90 degrees in phase with each other, and the opening / closing means is embossed or slit-shaped slots so that an occupant can sit on the seat. The skin material of the seat cover and the cover pad are elastically displaced in a curved shape, so that when an external force acts on the back base cloth attached to the cover pad in the outer peripheral direction centered on the seating portion, the back base cloth is applied to the back base cloth. Is a structure in which elongated opening / closing means are arranged in a zigzag pattern in which the longitudinal directions thereof are alternately phased by 90 degrees, and are bonded to a cover pad by having an adhesive portion and an adhered portion of the opening / closing means portion. because there is, Country, deformation of Hirakichijimi means in the width direction,
Displacement is remarkable, and it is possible to open and contract following the elastic displacement of the skin material and cover pad by comprehensive deformation and displacement of each opening and contraction means, so that creases will occur on the skin material side. The effect of is prevented.

[0005]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a sectional view of a seat cover 1, FIG. 2 is a plan view of a back base cloth 6, and FIG. 3 is a line AA in FIG. A cross-sectional view is shown. This seat cover 1 is made of the same fabric,
A skin material 2 made of vinyl chloride leather or the like, and a cover pad 3 made of a urethane foam slab adhered to the skin material 2.
And a back base cloth 6 made of a non-woven fabric that is adhered to the cover pad 3.

The non-woven fabric which is the back base fabric 6 is a sheet form in which the fibers are formed into an aggregate without being made into threads, and the fibers are adhered to each other and compressed into a thin cloth form to form an uneven embossing process in the compression process. The shape of the uneven embossing 7 (also referred to as opening and contracting means) formed in the shape of an ellipse is as shown in FIGS. 2 and 3 (for example, longitudinal direction l = 20 mm, width w = 10 mm, depth t).
= 1 mm) and a recess 7a is formed on the back side of the emboss 7, and as shown in the drawing, the emboss 7 is arranged in a zigzag pattern in which the longitudinal direction 1 is alternately 90 degrees in phase. There is.

When the non-woven fabric, which is the backing fabric thus formed, is laminated and adhered to the back side of the cover pad 3, a non-adhesive part 9 is formed in the adhering part 8 and the embossing 7 part as shown in FIG. . When the occupant sits on the seat cover 1 with the back base cloth 6 adhered to the seat cover 1 as described above, the seat cover 1 as shown in FIG. 4 (b) and FIG. The skin material 2 and the cover pad 3 are elastically displaced in a curved shape.
Due to the elastic displacement of the cover pad 3, an external force F acts on the back base cloth 6 attached to the cover pad 3 in the outer peripheral direction around the seat portion.

As described above, the back base cloth 6 which receives the external force F is provided with the oval-shaped embosses 7 in a zigzag pattern in which the longitudinal directions thereof are alternated by 90 degrees, and the adhesive portions 8 are formed on the cover pad 3. Since the embossing 6 and the adhered portion 9 are bonded together, the deformation / displacement of the embossing 7 in the width w direction is particularly remarkable. Since it is possible to open and contract following the elastic displacement of the skin material 2 and the cover pad 3, it is possible to prevent the generation of the creases 5 on the skin material 2 side.

FIGS. 6 and 7 (a) (b) show another mode of the opening / shrinking means formed on the non-woven fabric. The backing base fabric 10 has slit-like slots 11 instead of the embosses 7. The slit-shaped slot 11 has a length l =
It is formed to have a width of about 20 mm and a width w of about 1 mm, and is arranged in a zigzag pattern in which the length directions thereof are alternately phased by 90 degrees as shown in the figure as described above. By adhering the back base cloth 10 thus formed to the cover pad 3, the bonded portion 8 and the slit-shaped slot 11 become the adhered portion 9, whereby the slit-shaped slot hole is formed in the same manner as described above. Numeral 11 can follow the elastic displacement of the skin material 2 and the cover pad 3 to prevent the generation of the crease 5 on the skin material 2 side.

In the above embodiment, the means for opening and contracting the oval-shaped embossing 7 and the slit-shaped slot 11 has been exemplified, but the invention is not limited to this, and an elongated embossing or hole, for example, an ellipse. 9 each other in shape, diamond shape, etc.
It suffices as long as the opening and closing means are arranged in a zigzag pattern with 0 degree phase and can be opened and closed in the x and y directions.

[0011]

As described above, according to the present invention, when the occupant sits on the seat as described above, the skin material of the seat cover and the cover pad are elastically displaced in a curved shape, whereby the backing cloth attached to the cover pad is When an external force is applied in the outer peripheral direction centered on the seating portion, elongated back-and-forth opening and closing means are arranged in a zigzag pattern in which the longitudinal directions thereof alternate in 90 degrees, and the back base cloth is bonded to the cover pad. Since it is bonded by having the portion and the adhered portion of the opening / closing means portion, the deformation / displacement of the opening / closing means in the width direction is particularly remarkable, and the total deformation of each opening / closing means. -By the displacement, it is possible to open and contract following the elastic displacement of the skin material and the cover pad, so that it is possible to prevent the generation of creases on the skin material side.
