[0005] However, if a parting line is arranged at the corner of the connecting portion and the flange portion in the molding die for forming the back pad in which the ring-shaped protrusion is formed at the connecting portion, the ring-shaped protrusion provided on the back pad will Since the mold cannot be opened because it will be located further outside the rotation path of the upper mold, the parting line must be placed on the ridge of the ring protrusion
In this way, there are following problems: the air stagnant in the corner of the joint part and the flange part cannot be exhausted, and the outer surface of the corner part of the joint part and the flange part of the formed back pad is likely to be insufficiently filled, etc. bad

Embodiment Construction
[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0024] Figure 1 ~ Figure 4 The back pad 10 of the illustrated embodiment is a pad used as a cushioning material in, for example, a backrest in a rear seat of an automobile. The back pad 10 includes a pad main body 12 made of an elastic foam such as soft urethane foam, and a reinforcing cloth 14 laminated and integrated on the back side thereof. The back pad 10 is covered with an unillustrated skin material made by stitching woven fabric or leather, etc., and is assembled into the frame 4 (refer to Figure 4 ), thereby constituting the backrest.
[0025] On the upper edge portion in the back side of the pad body 12 , an inward flange-like protrusion 16 including a coupling portion 18 and a flange portion 20 is integrally provided. The frame 4 is disposed between the pad main body 12 and the protruding portion 16 .
[0026] The connecting portion 18 extends from the ...

Through holes and an annular protruding portion protruding upwards from the periphery of the through holes are formed on a connection portion extending from the upper edge portion of a cushion body to the rear side while ensuring the formability. A cushion body 12 with soft foam, the connection portion 18 extending from the upper edge portion of a cushion body 12 to the rear side, the protruding rim portion 20 spaced from the back of the cushion body 12 and extending downwards, through holes 32 vertically through the connection portion 18, and the annular protruding portion 34 protruding upwards from the periphery of the through holes are foamed and integrated into the back cushion 10 of the seat through a forming die 50. An outward recessing portion 21 is arranged on the boundary of the inner surfaces of the connection portion 18 and the protruding rim portion 20.
Description
technical field [0001] The present invention relates to a back pad for a seat used in automobiles and the like and a method of manufacturing the back pad for a seat. Background technique [0002] Generally, a back pad used as a cushioning material in the backrest of a vehicle seat consists of a molded product of foamed resin such as soft urethane foam, which is assembled into a metal frame, and a skin material is covered on the pad surface, etc. And the backrest part of the vehicle seat is comprised. The back pad for a seat is provided with an inwardly protruding portion including a connecting portion extending rearward from the upper side of the pad body and a flange portion extending downward from the connecting portion at a distance from the back surface of the pad body. In one piece, forming a bag shape with an open back, the frame is held between the pad body and the protrusion. [0003] When the back pad is foam-molded, a three-part molding die including the followin...
