Description

DETAILED DESCRIPTION OF THE INVENTION Cushioning articles with pads (hereinafter referred to as pads) include office chairs, motorcycle saddles, and the like.

Conventionally, the method of manufacturing this woodcutter's pad was to bond a rayon base material 3 to a PVC-based soft sheet 2 as shown in 1ii5.
) 4 (Z) is generally used, in which a composite sheet 4 is pasted with #1 and filled with a soft binding material 5 such as urethane foam.

However, with this method, the three-dimensional shape requires a base material S, so the composite seam is 4 m! It is difficult to form and process it, so it has to be cut into the required shape, sewn to the thinnest, etc., and the S layer to be made to the thinnest, etc., which takes 7 tons of man-hours.

For example, if there is no base material, soft PVC material is molded as a skin material and then molded into a cylindrical steel plate) (1) Thickness α6B~α
5. The frequency of the epidermis is too weak and the sheet thickness is too thin.
, if the thickness is increased to 0, etc., there was a problem that the soft feel would be lost.The present invention has not been able to solve this problem as a result of careful consideration, and requires steps such as **. Thermoplastic 1 is used in the manufacturing method of the cushioning article with a skin of the present invention.
2 stick sea) The step of shaping with a k female mold, and the above-mentioned true g! A fiber base material having an air permeability of 1F is placed on the molded glass sheet cabinet, and then a foamable synthetic resin stock solution is injected and foamed. As a thermoplastic glass snack sheet, it does not matter if it is Atsumachi Hasetsu 12 Stex which has a flexibility of R'45, but a sheet made of normal wire soft polyvinyl chloride is suitable, even if it is made of To9 foam. 6. Also, as the breathable fiber base material, knitted fabrics such as knitted fabrics or carpets such as kimono cloth may be used, or nonwoven fabrics may be used.

It may be 4bO. The breathable material of the housing must be highly extensible, and must have a phase-change elongation rate. -F vacuum forming, rutted fiber material is wrinkled on the inner surface, and then foaming component M and biased fat stock solution' are injected and foamed, or vacuum forming is performed.
You can step out the 11-12 stick sheet and set it in another Oka-sized female mold before moving on to the next process, or you can move to the deoxidizing Jin and Na (Kyuko A). Good. One-hole vacuum molded resin inner oriented t-emboss knife machining is optional.The present invention will be described in detail below with reference to Figure In which shows an embodiment. Figures 1 to 3 rJ show the molding process of the present invention, in which a porous material 8 as shown in Figure 1 is placed in a female Hatake vacuum forming mold 7 horizontally inside the mold. α5~α5aIIIl rhinoceros soft polyvinyl chloride sea) 2
kA blank molding ・12 11 [l must be 12 embossed] Next, as shown in FIG. At the same time, foaming polyurethane coolant 5 was injected.
By foaming the upper mold 9 (Fig. 5), the rayon cloth 5 is pressed against the F-sheet 2 side by the foaming pressure of the urethane foam, and at the same time, between the sheet 2 and the rayon cloth 6. A thin furetane additive layer 10 is formed, and the sheet 2 and the rayon cloth 5 are integrated into a contact layer (see Figure 4). It will not be used as a substitute.

As described above in the present invention, molded fL7'C-Plasticity 1
The inner surface of the rustic sheet is coated with a fibrous base material R * and then a foaming liquid is injected into it to harden it by foaming. A cushioning article with a padded leather that has a strong texture, etc., or one that can be manufactured on a contract basis for 6 km.
