く行なうことが困離であることの欠点があった。Conventionally, when a notebook pad is integrally molded with a notebook frame, as shown in FIGS. The seat butt molding material leaks out of the molding mold cavity from the root part 4 of 3, and post-processing is required. /-The notch part 6 of the dopant 2 is molded by cutting out a part of the seat pad 2 after completion of foam molding, and at the same time, the cutout part 7 of the seat frame 1 is formed by cutting out a part of the seat pad 2. Post-processing such as cutting out the seat pad 2 is required to expose the take-out surface 8, and furthermore, it is difficult to position the seat frame 1 relative to the seat pad 2 in a short time and with high precision. There was a drawback.

れることはない。FIG. 3 shows a take-up part 7 for a reclining adjuster arm 5, which is a part of the seat frame 1, between a plate 10 and a leaf spring 11 arranged in parallel inside the cavity of the upper mold 9. 1 shows a state in which the hand 2 is press-fitted and fixed, and the hand 2 is integrally molded with the seat frame 1. Here, the plate 10 is integrally molded with the upper mold 9, and the leaf spring 11 is fixed to the upper mold 9 with a mounting screw 13 or the like. The plate 10 and the leaf spring 1
When the mounting portion 7 of the seat frame 1 is inserted between the plates 10 and 1, the mounting portion 7 is inserted into the plate 10 so that the mounting surface 8 is brought into close contact with the plate 10 by the force of the plate spring 11. −
io is forced to visit. Therefore, the molding material is foamed in the second mold 9 and the lower mold 12, and the seat pad 2
When the seat frame 1 is molded, not only is the seat frame 1 positioned relative to the seat pad 2 in the vehicle width direction (direction of arrow A), but also the plate 10 occupies the seat pad 2 during molding. After the molding is completed, the formed portion forms the notch 6 shown in FIG.
This serves to expose the first surface 8 of the seat frame 1 from inside the seat pad 2. Note that the tip 14 of the leaf spring 11 is curved so that the mounting portion 7 of the seat frame 1 can be easily inserted between the spring 11 and the plate 10 against the force of the leaf spring. Even when the mold 9 is pulled away from the lower mold 12, the tip 14 will not damage the sorting pad 2 since the dopant 2 is soft and bends.

Yes, but it's okay. Further, in the illustrated embodiment, the plate spring 11 constitutes the biasing part, but instead of the plate spring 11,
An elastic member such as synthetic rubber may also be used. Further upper mold 9
The protruding portion and the biasing member may both be provided side by side on the lower mold 12, or one may be attached to the lower mold 12 so as to face the other. Good too.

When the upper mold 9 and the lower mold 12 are combined, the base portion 4 of the N-I frame 1 covered with This shows a state in which the N-i band 2 is integrally molded with the notebook frame 1 after being gripped and fixed by the slits 16 and 17. When the upper mold 9 and the lower mold 12 are combined, the gap between the root portion 4 of the notebook frame 1 and the slits 16 and 17 is completely sealed by the urethane material 15. Therefore, when the molding material is foamed in the upper mold 9 and the lower mold 12 and the seat pad 2 is molded, the seat frame 1
Not only is the molding material prevented from leaking out from the root portion 4 of the frame 1 in the direction of the protruding portion 3 of the top plate 1, but also the molding material is prevented from leaking from the root portion 4 of the notebook frame 1 to the seat pad 2 in the front-rear direction (in the direction of the arrow). Rank B: Decisions are made forcibly 1
, In this embodiment, Surin l-16 and 17 are respectively attached to the upper mold 9. Although it is molded integrally with the lower mold 12, the slit is formed in the upper mold 9. It may be constructed of different members each fixed to the lower mold 12 with several screws or the like, or a seal member interposed between the sulin 16 and 17 and the base portion 4 of the seat frame 1 may be used. In and 17, natural rubber or the like may be used instead of the urethane material 15.

成形用材オ・Ｉを発泡させればよい。The operation using the manufacturing method 4-1 of the present embodiment may be performed by simultaneously performing the operations shown in FIGS. 3 and 4. That is, the base portion 4 of the front sort frame 1 is covered with the urethane material 15, and then the seven-piece frame 1 is placed in the lower mold 12 for molding with the urethane material 15.
The base part 4 of the seat frame 1 which has been plowed in step 15 is set so as to be supported by the slit 17 formed in the lower mold 12, and then the upper mold 9 for molding is set.
The mounting part 7 of the frame 1 is combined with the lower molding mold 12 and placed inside the molding mold so that it is press-fitted between the plate 10 and the plate notches 11 attached to the upper molding mold 9. What is necessary is to foam the sheet plate forming material O.I.

う顕著な効果を奏する。The notebook manufacturing method according to the present invention has the above-mentioned configuration, and when the seat/gradle is integrally molded with the seat frame, a part of the sorting frame is attached to a protruding mold attached to the molding die. By being press-fitted and fixed between the seat support members, the 7-toe frame is automatically positioned, and at the same time, the seat (・frame installation (-1) required mounting surface is removed from inside the seat pad. Not only will it be exposed,
The other part of the notebook frame is held and fixed between the knots attached to the molding mold through the sealing material, thereby preventing the molding material from leaking out. At the same time, a remarkable effect is achieved in that the position of the frame is determined.
