Description

【考案の詳細な説明】（産業上の利用分野）本考案は車両用のシートクツシヨンパツドに関
するもである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a seat cushion pad for a vehicle.

（従来技術）従来、シートクツシヨンパツドには以下のよう
なものがあつた。(Prior Art) Conventionally, there have been the following seat cushion pads.

(1)注入発泡モールドによるもの、(2)チツプウレ
タンモールドによるもの、(3)スラブウレタン張り
付けによるもの等があつた。 There were (1) those using injection foam molding, (2) those using chip urethane molding, and (3) those using slab urethane pasting.

（考案が解決しようとする問題点）従来は前記の通りであつたため、(1)の注入発泡
の場合は、高精度の注入発泡機を必要とし、しか

タンモールドの場合は、重量が重くなることがあ
つた。(3)のスラブウレタン場合は、外観が悪く、
かつ形状が限定されていた。(Problems to be solved by the invention) Conventionally, as described above, injection foaming in (1) requires a high-precision injection foaming machine and requires heating at 150°C to 250°C to harden the foam. Requires a furnace;
The work efficiency was poor, as it took about 20 minutes from injection to mold release, and equipment costs were high. In the case of the chip urethane mold (2), the weight was sometimes heavy. (3) Slab urethane has a poor appearance;
And the shape was limited.

以上のことが問題となつていた。 The above was the problem.

イス材を使用している。 As shown in FIG. 1, the sheet cushion pad 1 according to the present invention is produced by coating both sides of a slab urethane 2 with a resin-impregnated slab urethane foam 3, inserting it into a mold (not shown), and pressurizing it with steam. It is formed by molding, and leg parts 5 are formed at the overlapping ends 4 of both resin-impregnated slab urethane foams 3 during pressure molding. In this embodiment, a soft urethane slice material having a specific gravity of about 0.025 is used as the slab urethane 2.
