Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a groove structure in a sheet hanging portion in which the groove of the hanging portion has a width in order to provide various aesthetic appearances as a sheet appearance forming means.

Conventionally, as a method for forming the appearance of a sheet, as shown in FIGS. 1 and 2, a suspension bag 5 is sewn onto the outer skin 2 of the changing surface of the sheet, a wire rod 6 is inserted into the bag, and this is A method in which the wire rod 7 on the side of the pad 4, which has been placed in advance inside the changing surface of the sheet and is integrally foamed, is connected with a clip 8, or a hot press molding method is known. However, in the former case, although it can be said to be a simple method in which the changing surface of the sheet is divided by a single hanging portion 1, it is a simple method for forming the sheet appearance. In the latter case, although it is possible to freely form the hanging portion on the changing surface of the sheet, there are restrictions such as the inability to use it depending on the skin material, and it is technically difficult. The present invention was developed in view of the above-mentioned circumstances, and by making the hanging part of the sheet changing surface into a wide groove, it can create a more diverse aesthetic appearance than the conventional one expressed by a single line. It is an object of the present invention to provide a groove structure in a sheet hanging portion configured to exhibit the following characteristics.

In order to achieve the above object, the present invention forms a pad groove portion having an appropriate width on the surface of the pad material corresponding to the hanging portion of the sheet changing surface, and a first strip tape having a bonding function is attached to the bottom surface of this groove portion. At the same time, a second strip tape having a bonding function is attached to the back surface of the seat skin via a strip shape retaining panel, and the first and second strip tapes are joined by adhesive to form the sheet changing surface. It is characterized in that a hanging groove having a constant width is formed in the hanging part.

Hereinafter, the present invention will be described in detail based on illustrated embodiments. FIG. 3 is a perspective view of a seat in which a hanging groove 9 having a constant width according to the present invention is formed in the seat surface, and FIG. 4 is a sectional view of the groove 9.
This hanging portion has the following structure.

A pad groove portion 10 slightly wider than the suspension groove 9 is formed on the surface of the pad material 4 corresponding to the suspension portion of the changing surface of the sheet. A band-shaped tape 11 having a bonding function is attached to the bottom surface of the groove 10 with the bonding surface facing upward. This strip tape (first strip tape) 11 is integrally foamed during foam molding of the pad material and attached to the bottom surface of the pad groove 10.

On the other hand, a strip tape (second strip tape) 12 having a bonding function is also attached to the back surface of the seat skin 2. This belt-shaped tape 12 is sewn to the back surface of the seat skin 2 via a belt-shaped shape-retaining panel 13 with the joint surface facing down. This band-shaped shape-retaining panel 13 is slightly wider than the width of the hanging groove 9 to be obtained, and is made of, for example, a synthetic resin plate, and this panel 13 prevents the groove 9 from losing its shape. .

By joining the strip tapes 11 and 12, a hanging groove having a constant width can be formed in the hanging portion of the sheet changing surface. The band-shaped tapes 11 and 12 can be joined by simply adhering the tapes together, and the joining is easier and more workable than using hog rings or clips.

As explained in detail above, the groove structure in the sheet hanging part according to the present invention is created by simply bonding tapes having an adhesive function to each other without using any fastening means such as hog rings or clips. Workability is good because structures can be formed. Furthermore, the hanging portion that forms a changing surface in the external shape of the sheet can produce a three-dimensional aesthetic effect compared to a simple single strip.

In addition, by forming grooves with appropriate width and depth not only in the hanging part on the seat changing surface but also in the body pressure distribution part of the occupant, breathability, holding performance, and cushioning performance can be improved. It is.
