As described in No. 980 and No. 58-138622, in order to prevent damage to the back surface of the cushion body due to the spring, the support material is made of polyester with a basis weight of about 100 g/2 mm and a thickness of about 1 mm. Coarse blankets are used. However, with such a supporter material, there is a problem that the foaming solution seeps through the supporter material to the contact surface of the urethane layer, and as a result, the urethane layer rubs against the urethane layer, causing abnormal noise. For this reason, for example, a silicone mold release agent is applied to the mold, or a silicone mold release agent is sprayed onto 7-ohm urethane in a post-process to lower the coefficient of friction and prevent noise. Since the durability of the silicon mold release agent is about 3 months, there is a problem in that an abnormal noise is generated after that.

をＷｆｆｉとするシートパッドの製造方法に係る。(Means for Solving Problem S) The present invention integrates the supporter material into the bottom surface of a seat pad made of polyurethane foam by injecting and foam-molding a urethane foam stock solution into a mold in which a supporter material is attached to an upper mold of a foam mold. The present invention relates to a method of manufacturing a seat pad in which Wffi is such that the supporter material is a woven fabric or a non-woven fabric with an air permeability of 5 to 300 cc/es+cm/see and a thickness of 0.6 to 10 mm.

By using such a supporter material, the urethane foaming stock solution will not penetrate through the supporter material, and therefore no abnormal noise will be generated due to friction between the urethane layer and the urethane layer.

型になじまない等、不適当である。Supporter materials that fall outside the shaded area of the graph in Figure 1 and have an air flow rate greater than 300cc/'c+*2/see, and those that fall to the left of straight lines (A) to (B). In this case, when the foaming pressure is high such as Cold Cure 7 ohm, the urethane foaming stock solution penetrates the supporter material, which may cause abnormal noises due to the friction between the urethane layer and the urethane foam. Also, ventilation 1 is 5 cc/cm'/s
If it is less than ee, a problem may arise in that voids (empty pockets) are generated at the interface between the supporter material and the urethane layer, resulting in interfacial peeling and failure to integrate. Furthermore, if the thickness exceeds 1θ-1, it is difficult to set it in a mold, and it is not suitable because it does not fit in the mold.
