その製造法に関するものである。
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cushion body for a seat formed by molding a frame of synthetic resin foam, and a method for manufacturing the same.

It is desired that this type of seat cushion body has cushioning characteristics that vary depending on the body part, so that even when seated for long periods of time, the user does not feel fatigued.

For this reason, a method has been adopted in which synthetic resin foam stock solutions with different hardnesses are simultaneously injected into the mold to form two or more flexible parts and hard parts with different hardnesses. A slight variation in the injection speed or amount of the synthetic resin foam causes the boundary position between the resulting soft part and hard part to shift, and furthermore, the boundary surface is unstable. For this reason, there is a drawback that a product of required specifications cannot be obtained.

There is also a method of forming a single type of synthetic resin foam molding and bonding them together to form a single cushion body for a seat.
Processing man-hours increase, making it unprofitable.

Furthermore, there is a method of molding the entire shape with synthetic resin foam and impregnating the molded body with a hard synthetic resin for slabs in the required places, but this also results in inconsistent impregnation and poor quality. Although it is stable, the impregnated layer feels like a foreign substance and is not comfortable to sit on.

Hereinafter, the present invention will be specifically explained based on illustrated embodiments. In the figure, numerals 1 and 2 are molds, and a frame 3 made of elastic metal wire or the like is loaded into the mold 1. Then, on this frame 3 or across the frame 3, a thermofusible synthetic resin, for example, a nylon polyamide resin is made.
A plate-shaped partition member 4 of about 50 μm to 150 μm is placed in the molds 1 and 2 to partition the internal space into two or more.
In each of these partitioned spaces, two or more synthetic resin foams having different hardnesses, such as Ultan, are used so that adjacent parts have different hardnesses, for example, a flexible part 5 and a hard part 6. Inject the resin foam.

The seat cushion body constructed in this manner, for example, the backrest member 7 and the seat member 8, each have a flexible portion 5 and a hard portion 6 at required locations, and the boundary surfaces thereof are accurately separated by the partition member 4. This allows for a stable supply of uniform products. Furthermore, the partition member 4 is softened and melted by the foaming heat of the synthetic resin foam injected on both sides thereof, and is integrated and attached to each foam. There is no risk of it being peeled off or decomposed.
