Moreover, it is an attempt to provide a loose cushion seat that is comfortable to sit on.

[Means to solve the problem]

The loose cushion sheet according to the present invention is a loose cushion sheet in which wading, in which a soft foam material is sandwiched between a skin material and a lining cloth, is placed on a molded form with a webbing interposed therebetween, in which the wading and the webbing is characterized by having a structure in which the central part of the upper surface is joined to the seater by welding, and the side parts of the upper surface are not joined.

The above loose cushion sheet is manufactured as follows. That is, the method for manufacturing a loose cushion sheet according to the present invention includes sequentially positioning a webbing cloth, a wading made of a backing cloth, a soft foam material, and a skin material between a mold electrode of a predetermined shape and an electrode plate, and A step of welding the force cloth and the wading together at the position of the blade of the die electrode corresponding to the center portion of the upper surface of the cushion sheet by applying it to the mold electrode; A process of placing the cloth in a stretched state on the electrode board and placing it with a bend on the side of the wading, and a step of placing the cloth placed on the electrode board, the end of the wading, and the side of the sheet. This method is characterized by the step of welding the edge of the skin material to the edge of the skin material, and placing the webbing and wading on the mold form.

〔Example〕

Embodiments of the present invention will be described below in detail based on the drawings, but the present invention is not limited to the following embodiments unless it exceeds the gist thereof.

This embodiment relates to a motorcycle seat processed by high frequency welding.

FIG. 1 of the accompanying drawings is an external view of the loose clothing according to the present invention, and relates to a structure in which only the side portions 15, 15 of the loose clothing sheet are not joined with the webbing. FIG. 2 is a sectional view taken along the line -- in FIG. 1 of the loose cushion sheet according to the present invention. In general, the loose cushion sheet 1 includes wadding 2, a mold form 3, a frame 4, and the like.

The wading 2 includes a skin material 5, a soft foam material 6,
It is composed of a lining cloth 7. In other words, the skin material 5,
A material in which a soft foam material 6 such as polyurethane, polyvinyl chloride, or rubber foam is bonded to a backing cloth 7 is used.

The skin material 5 is made of cloth, synthetic leather, fabric, or the like. The webbing 8 is made of knitted fabric, nylon, or other material with strong tensile strength. As shown in Fig. 6, the edge of the cushion is covered with a skin material 1 that covers the gusset part of the cushion.
1. After joining the skin material 5, backing cloth 7, and webbing cloth in a desired shape, bend the mold form 3 in the direction of arrow a, and drive fixing tools 13 such as tassels or nails into the frame 4 to tension it. will be established.

As the mold form, semi-rigid urethane foam, polyethylene, polyvinyl chloride foam, etc. are used. And mold form 3
is covered with a covering film 9 made of polyethylene or the like to ensure good sliding with the webbing.

Normally, all the desired joints of a quilting structure are joined together with the dressing cloth, lining cloth, etc., but in the present invention, as shown in FIG. Both sides of the top surface of 1
5 and 15, only the outer skin material 5 and the back cloth 7 are joined by welding, and the center part of the upper surface for the seater is not joined to the webbing 8 by welding. In other words, conventionally, all of the wadding 2 is joined to the webbing 8 even in the side part 15, so even if the quilting structure of the cushion can take some sagging, the amount is small and is not effective. It was not possible to generate wrinkles, and the cushioning effect could not be sufficiently exhibited. According to the present invention, on both sides of the cushion, as shown in FIG. 7, the wading 2 is not in close contact with the webbing 8, and even if the webbing 8 is fixed in a strongly tensioned state, the loose cushion sheet is The loose feel does not deteriorate, and the cushioning effect can be fully demonstrated. In addition, as shown in FIG. 2, in the longitudinal direction (front-back direction or up-down direction) of the person sitting on the loose cushion seat 1, the quilting structure is such that the outer material 5, the lining material 7, and the webbing material 8 are integrated. As a result, a zygote is formed. This results in
The seater's position in the vertical direction can be maintained in a sufficiently stable manner as before.

Next, a method for producing quilting of a loose cushion sheet by high-frequency welding, which is one of the embodiments of the present invention, will be described. Figures 3 to 6
The figure is a schematic diagram showing a vertical cross-sectional view for easy understanding when carrying out the manufacturing method of the present invention, and FIGS. 3 to 6 show the movement according to the process order of the method of the present invention. It represents.
