本発明は布地付アームレストの製造方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of manufacturing an armrest with fabric.
従来の布地付アームレストとしては例えば第８図に示す
ようなものがある。（特開昭５９−３１１５３号参照）
すなわち、図において、１はポリプロピレン（Ｐ Ｐ）
等の材料で射出成形により形成したアームレスト本体、
２はこのアームレスト本体１の上面に設けたパッド部で
、例えば発泡ウレタンフオーム材よりなるバンド材３と
、このパッド材３に埋設されその取付脚部４ａが前記ア
ームレスト本体２ａの上面に穿設した取付孔１ａに係止
された芯材４と、前記パッド材３を被覆する布地５とに
より形成されている。As a conventional armrest with cloth, there is one shown in FIG. 8, for example. (Refer to Japanese Patent Application Laid-Open No. 59-31153.) In other words, in the figure, 1 is polypropylene (PP).
The armrest body is formed by injection molding from materials such as
Reference numeral 2 denotes a pad portion provided on the upper surface of the armrest main body 1, which includes a band material 3 made of, for example, a foamed urethane foam material, and a mounting leg portion 4a embedded in this pad material 3, which is bored into the upper surface of the armrest main body 2a. It is formed by a core material 4 that is locked in the attachment hole 1a, and a fabric 5 that covers the pad material 3.
しかしながら、このような従来の布地付アームレストに
あっては、パッド部２がアームレスト本体１と別体で、
構造が複雑であり、かつパッド部２の布地５も後貼りで
作業工数がかかるとともに、これらが相俟ってコスト高
となるという問題点があった。However, in such conventional armrests with fabric, the pad part 2 is separate from the armrest main body 1,
The structure is complicated, and the fabric 5 of the pad portion 2 is pasted on later, which requires a lot of man-hours, and these factors together result in high costs.
本発明はこのような従来の問題点に着目してなされたも
ので、構造が簡単で作業工数の少ない安価な布地付アー
ムレストが得られ、しかも布地の位置保持性が確実でア
ームレスト本体から剥がれにくいようにした布地付アー
ムレストの製造方法を提供することを目的とする。The present invention has been made by focusing on these conventional problems, and it is possible to obtain an inexpensive armrest with fabric that has a simple structure and requires less man-hours.Moreover, the fabric retains its position reliably and is difficult to peel off from the armrest body. It is an object of the present invention to provide a method for manufacturing an armrest with fabric as described above.
本発明はかかる目的を達成するため、アームレスト本体

空隙の上流側に設けたゲートの開口より前記樹脂射出空
隙内に溶融樹脂を射出注入し、流れる樹脂により前記布
地の見切部が前記金型に押さえつけられるようにしたも
のである。In order to achieve such an object, the present invention has a parting section of a fabric to be covered on the upper surface of the armrest body, which has been previously formed into a product shape, inside an injection mold for injection molding the armrest body. The molten resin is set to be placed in a concave gap formed in a part of the resin injection gap, and the molten resin is injected into the resin injection gap through the opening of a gate provided on the upstream side of the concave gap. The parting part of the fabric is pressed against the mold.
アームレスト本体の射出成形特布地が一体に取りつくが
、この際布地はその見切部が流れる樹脂により金型に押
さえつけられているため、位置保持される。The special injection-molded fabric of the armrest body is attached to the armrest body, but at this time, the fabric is held in position because the parting part of the fabric is pressed against the mold by the flowing resin.
以下図面を参照して本発明の一実施例を説明する。 An embodiment of the present invention will be described below with reference to the drawings.

体閉型する。In FIG. 1, a fabric 11 to be covered on the upper surface of the armrest main body, which will be described later and has been previously formed into a product shape, is placed in a predetermined position in an outer mold (commonly called a cavity mold) 12 for injection molding the armrest main body. In this state, the outer mold 12 is combined with the inner mold (commonly called core mold) 13 and closed.

るようにする。In this case, as shown in detail in FIG.
3 and the parting part of the fabric 11 in the outer mold 12 (
A concave groove 14 and a protrusion 15 are formed in the portions corresponding to the lower end edge) 11a, respectively, to form a part of the resin injection cavity (corresponding to the shape of the armrest body) 16 into a concave cavity 17. The parting portion 11a of the fabric 11 is kept in place.
また、合体した前記外側金型１２および内側金型１３に
より形成される樹脂射出空隙１６に溶融樹脂を射出注入
する複数のゲート１８の開口は前記凹状空隙１７の上流
側に設けておく。Further, openings of a plurality of gates 18 for injecting molten resin into the resin injection cavity 16 formed by the combined outer mold 12 and inner mold 13 are provided on the upstream side of the concave cavity 17.
次に前記ゲート１８により溶融樹脂１９を樹脂射出空隙
１６に射出注入する。この場合、各ゲート１８の開口か

際、凹状空隙１７において、流れる溶融樹脂１９により
布地１１の見切部１１ａが外側金型１２の突条１５に押
さえつけられるようになっている。Next, the molten resin 19 is injected into the resin injection gap 16 through the gate 18 . In this case, the molten resin 19 injected from the opening of each gate 18 first flows while being dispersed in the direction of the arrow, as shown in FIG. flows to the side. At this time, the parting portion 11a of the fabric 11 is pressed against the protrusion 15 of the outer mold 12 by the flowing molten resin 19 in the concave space 17.
かくして樹脂射出空隙１６に溶融樹脂１９が完全に充填
された後、該溶融樹脂１９を固化させ内、外側金型１３
．１２から外せばアームレスト本体の射出成形工程は終
了し、第４図に示すようなアームレスト本体２０に布地
１１が一体に徽り付いた布地付アームレスト２１が形成
される。After the resin injection cavity 16 is completely filled with the molten resin 19 in this way, the molten resin 19 is solidified and the inner and outer molds 13 are
．． Once removed from the armrest body 12, the injection molding process for the armrest body is completed, and an armrest 21 with fabric is formed in which the fabric 11 is integrally attached to the armrest body 20 as shown in FIG.
なお、第４図において、２２は布地付アームレスト２１
が取り付けられたドアである。In addition, in FIG. 4, 22 is an armrest 21 with fabric.
This is a door with an attached door.

で、しっかりとアームレスト本体２０に取り付き、剥が
れにくいものとなる。The armrest 21 with fabric manufactured in this way looks the same as the conventional one, but has an extremely simple structure in which the fabric 11 is simply attached to the armrest body 20, and the injection molding process of the armrest body 20 Since it can be completed all at once, it requires fewer man-hours and is inexpensive. Furthermore, during injection molding, the parting part 11a of the fabric 11 is pressed against the protrusion 15 of the outer mold 12 by the flowing molten resin, so that the fabric 11 is reliably held in position, firmly attached to the armrest body 20, and does not peel off. It becomes difficult.
また、使用時においても布地１１はその見切部１１ａが
凹部内に位置するため、乗員の手や物品が接触すること
がなく、剥がれにくくなっている。Further, even during use, the parting portion 11a of the fabric 11 is located within the recess, so the occupant's hands and articles do not come into contact with the fabric 11, making it difficult to peel off.

3.23. . . . are provided in a protruding manner, and as shown in FIG. The parting part 11a of the fabric 11 placed in the concave gap 17 is intermittently held between the inner bottom surface of the concave groove 14 in the inner mold 13, and the injection pressure during injection molding is applied. Preventing the fabric 11 from shifting,
This provides even better position retention. In this case, protrusion 2
The larger the width W of 3, the greater the effect. In this example, the shape of the manufactured armrest main body 20 is as shown in FIG. 7.
