Abstract
ABSTRACT OF THE DISCLOSURE
A pad article with supporter sheet capable of preventing the appearance of the flash of liquid foam resin at the parting line of the mold in the manufacturing process, so that cumbersome a labor of removing the flash can be omitted and thereby the efficiency of the manufacturing process can be improved. The pad article includes a supporter sheet to be combined with the pad member, having extended portions extending out from the pad member, the extended portions being held at parting lines between the lower mold and the upper mold when the upper mold and the lower mold are assembled.

Description
~035~3 PAD ARTICLE WITII SUPPORTER SHEET
B~CKGROUND OF THE INVENTIO~
Field of the Invention The present invention relates to a pad article with supporter sheet combined such as that to be utilized for an automobile seat.
lC Description of the Background Art Conventionally, as shown in Fig. 1, in manufacturing of a pad article 1 to be used for an automobile seat by making a pad member 3 from liquid foam resin, a su~porter sheet 5 is attached to a bottom face of an upper mold 13, and the upper mold 13 with this supporter sheet 5 attached is assembled with the lower mold 12 after the liquid foam resin has been poured into the lower mold 12, so that the pad article comprising the pad member 3 and the supporter sheet 5 combined together can be obtained.
~O However, conventionally, when the pad article 1 was manufacturing as described above, a flash of the liquid foam resin 3a appeared at a parting line 15 between the upper mold 13 and the lower mold 12, a removal of which required a cumbersome labor.
SUMMARY OF THE INVENTION
It is therefore an ob~ect of the present invention to provide a pad article with supporter sheet capable of preventin~ the appearance o~ the Plash of liquld Poam resin at the parting llne of the mold in the manufacturing process, so that a cumbersome labor of removing the flash can be omitted and thereby the efficiency of the manufacturing process can be improved.
This ob~ect is achieved ln the present invention by 5~3 providlng a pad artlcle to be manufactured by a mold compris1ng an upper mold and a lower mold, the pad article co~prisin~: a pad member to be made from liquid ~oam resin poured into a lower mold; and a supporter sheet to be combined with the pad member, having extended portions extending out from the pad member, the extended portions being held at parting lines between the lower mold and the upper mold when the upper mold and the lower mold are assembled.
Other features and advantages of the present invention will become apparent ~rom the following description taken in con~unction with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
Fig. 1 is a partial cross sectional view of a mold in a process o~ manufacturing a conventional pad article, for explaining a problem associated with the manufacturing of a conventional pad article.
Fig. 2 is a partial cross sectional view of one embodiment of a pad article with supporter sheet according to the present invention.
Fig. 3 is a partial cross sectional view of a mold in a process of manufacturing the pad article o~ Fig. 2.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to Fi~. 2, there is shown one embodiment of a pad article with supporter sheet according to the present invention.
In this embodlment, a pad article 21 comprises a pad member 23 to be made from liquid foam resin, and a supporter sheet 25 combined with the pad member 23 at a bottom of the pad article 21.
The supporter sheet 25 is made of a non-woven fabric, X0~3583 a rough cloth or a lawn, and has a thickness of approximately 3mm. Moreover, the supporter sheet 25 has such a size that an end portion 25a extends out to a side o~ the pad member 23 ~or a substantial length. This end portion 25a wlll be held at a partlng line between an upper mold and a lower mold in manu~acturing the pad article 21.
This pad article 21 is manu~actured as follows.
First, the supporter sheet 25 is attached loosely to the upper mold 13 by means o~ pins or double sided tapes.
Then, as shown ln Fig. 3, the upper mold 13 with the supporter sheet 25 attached is assembled with the lower mold 12 such that the end portion 25a is held at the parting line 15 between the upper mold 13 and the lower mold 12.
Next, the liquid foam resin 23a is poured into the lower mold 12 through openings 26 and 27 provided on the upper mold 13 and the supporter sheet 25, ~espectively, by a nozzle 28. The liquid ~oam resin 2~a subsequently undergoes the ~oaming process to become the pad member 23.
When the ~oamln~ process is completed, the resulting pad article 21 is li~ted out o~ the lower mold 12.
Here, because of the presence o~ the end portion 25a at the parting llne 15, no flash of the liquid ~oam resin 23a appears when the liquid foam resin 23a is poured into the lower mold 23. Instead, the liquid foam resin 23a will penetrate into the end portion 25a, so that this end portion 25a will stiffen by the time the pad article 1 is li~ted out of the lower mold 12.
The pad article 21 so obtained will then be covered by a skin cover, and the ends o~ the skin cover as well as those of the supporter sheet will be attached to a seat ~rame. Here, the ends of the supporter sheet can be made to contact the seat frame directly whlle the ends o~ the skin cover is attached over the supporter sheet, so as to prevent damaging of the skin cover by the seat frame.
20035a3 Thus. according to the present inventlon, it ls possible to obtaln a pad artlcle with supporter sheet capable of preventing the appearance of the flash of liquid foam resin at the parting line of the mold in the manufacturing process, so that a cumbersome labor of removing the flash can be omitted and thereby the efficiency of the manufacturing process can be improved.
It is to be noted that the skin cover may be placed on the lower mold before the liquid foam resln is poured so that the skin covered pad article can be obtained.
Besides this, many modifications and variations of the above embodiments may be made without departing from the novel and advantageous features of the present invention.
Accordingly, all such modifications and variations are intended to be included within the scope o~ the appended claims.
