The seat cushion includes a seat 5 and a backrest cushion 1, and the mechanical component storage unit 2 is normally stored in a side portion of the backrest cushion. However, the mechanical component storage section is not limited to the back cushion, and may be stored in the seat cushion. It is only preferable that the back cushion side part is preferable in view of the indirect load.

Since the distance L 1 between the pipe surface A and the slit B is smaller than the maximum dimension L 2 of the relief shape of the mechanical component storage portion, it is not possible to extract a nest (not shown) made of aluminum, iron or plastic in the F direction. Not possible without destroying the shape. Mechanical parts storage (Lumber)
In the present invention, it is not removable in the present invention, and the synthetic resin molding hollow body 4 of FIG. 4 which is closely adhered to the mechanical component storage portion is made in advance, placed on the mold, and the soft polyurethane foaming stock solution is injected, After curing and heating, the mold is removed, and when the mechanical parts are mounted, the synthetic resin molded hollow body cutting and discarding part is cut from the synthetic resin molded hollow body cutting part 7, and the necessary mechanical parts are mounted.

It is made by blow molding of polypropylene or polyethylene resin. The thickness of blow molding is designed according to the required strength, but it is required to be 0.2 to 2.3 mm in order to maintain the hardness as a sheet that is not felt when sitting. 0.2 mm
Below, the buckling strength is weak, and when it is 2.3 mm or more, the cushioning property is deteriorated. 0.6-1.2 mm is desirable
The degree is desirable. This is attached to the required position of the mold of the seat cushion pad and integrally molded with the soft polyurethane foam stock solution. After heating and aging, the mold is removed from the mold, and a thin cutting and discarding part (0.1 to 0.5 mm) that is easily processed is cut and opened, and necessary mechanical parts are mounted. If the thickness of the cutting and discarding part is less than 0.1 mm, it may be cut during the work, and if it is more than 0.5 mm, the cutting is troublesome and time-consuming.

の効果がある。According to the conventional "nesting" method, the mold releasing agent on the surface of the "nesting" remains around the foam when the mold is removed, and when the mechanical parts are mounted at that place, the mold releasing agent adheres to the mechanical parts. However, although there was a drawback that the shape of the foam was not retained and the human body was loaded on the mechanical parts, the molded hollow body made of synthetic resin had the shape retention and the mechanical parts did not come into direct contact with the urethane foam. It has a great effect on maintaining the function of parts.
