【産業上の利用分野】[Industrial applications]

本考案は、自動車用シート(座席)などの車両用シートのクッション体として 使用される異硬度パッド、詳しくは、成形型内に仕切壁を設けて高硬度パッドか らなるサイド部と低硬度パッドからなる着座部とを一体に発泡成形して車両用シ ートの異硬度パッドに関する。 The present invention is a pad of different hardness used as a cushion for a vehicle seat such as an automobile seat (seat), and more specifically, a side wall and a low hardness pad that are formed of a high hardness pad by providing a partition wall in the mold. A different hardness pad for a vehicle seat that is integrally foam-molded with a seating part made of.

【0002】[0002]

【従来の技術】[Prior art]

従来の自動車用シートのパッドには、図7に示すシートクッションのパッド( P)の如く着座部(1)に低硬度パッドを使用して着座感を、また、着座部(1 )の左右に有するサイド部(2)(2)を高硬度パッドを使用して、ホールド性 を夫々向上させているものがある。 In a conventional automobile seat pad, a low hardness pad is used for the seating portion (1) like the seat cushion pad (P) shown in FIG. 7, and the seating feeling is provided to the left and right of the seating portion (1). Some of the side portions (2) and (2) have a high hardness pad to improve the holding property.

【0003】 この図7に示すパッド(P)は、図9に示す方法で発泡成形している。 即ち、成形下型(5)内に、パッド(P)を被覆する表皮(不図示)吊込用の 凹溝を形成する突起(3A)と、この突起(3A)に仕切壁(4A)を一体に設 け、この仕切壁(4A)に仕切られた一方に、高硬度パッド発泡用の発泡液(2 A)、他方に、低硬度パッド発泡用の発泡液(1A)を夫々注入して、発泡成形 して、図7、8に示すようなパッド(P)を成形している。The pad (P) shown in FIG. 7 is foam-molded by the method shown in FIG. That is, in the lower molding die (5), a projection (3A) forming a groove for hanging a skin (not shown) that covers the pad (P) and a partition wall (4A) are formed on the projection (3A). The foaming liquid (2 A) for foaming the high hardness pad and the foaming liquid (1 A) for foaming the low hardness pad are respectively injected into one of the partitions provided on the partition wall (4A) and the other. Then, foaming is performed to form a pad (P) as shown in FIGS.

【0004】 即ち、成形下型(5)の突起(3A)に対応する部分が、表皮吊込用の凹溝( 3)、仕切壁(4A)に対応する部分がスリット(4)となる。That is, the portion corresponding to the protrusion (3A) of the lower molding die (5) is the concave groove (3) for suspending the skin, and the portion corresponding to the partition wall (4A) is the slit (4).

【0005】[0005]

【考案が解決しようとする課題】[Problems to be solved by the device]

以上のパッド(P)は、着座部(1)とサイド部(2)の上面側の境界に設け た凹溝(3)の底部にスリット(4)が形成されており、サイド部(2)には、 乗員の着座時、乗降時に、着座部(1)に対して外方に負荷が加わる。 そのため、スリット(4)の下方に、応力が集中し、図8に示すようにパッド (P)に割れ(41)が発生し、シートの長期使用により、サイド部(2)が着 座部(1)から分離する虞れがあった。 In the above pad (P), the slit (4) is formed at the bottom of the concave groove (3) provided at the boundary between the seating portion (1) and the side portion (2) on the upper surface side, and the side portion (2) is formed. When the occupant is sitting or getting on and off, a load is applied to the seating portion (1) outward. Therefore, stress concentrates below the slits (4), and a crack (41) occurs in the pad (P) as shown in FIG. 8, and the side portion (2) is seated on the seat portion (2) due to long-term use of the seat. There was a risk of separation from 1).

【0006】 そこで、本考案は、上述の如く、パッドのサイド部を着座部と異硬度の発泡体 で一体成形してなるものにおいて、サイド部と着座部との間に割れが生じないよ うにすることを目的とする。Therefore, in the present invention, as described above, in the side portion of the pad integrally formed with the seat portion by the foam of different hardness, cracks do not occur between the side portion and the seat portion. The purpose is to do.

【0007】[0007]

【課題を解決するための手段】[Means for Solving the Problems]

以上の目的を達成するための本考案は、高硬度パッドからなるサイド部と低硬 度パッドからなる着座部との間に、パッド発泡用の成形型における仕切壁によっ て形成されるスリット内に、接着剤、若しくは、相互に係合する連結部材を設け て、スリットによって分離される部分のサイド部と着座部を一体にしてなるもの である。 To achieve the above object, the present invention provides a slit formed by a partition wall of a pad foaming mold between a side portion made of a high hardness pad and a seating portion made of a low hardness pad. An adhesive agent or a connecting member that engages with each other is provided on the upper side, and the side portion and the seating portion separated by the slit are integrated.

【0008】[0008]

【作用】[Action]

サイド部はスリット部分において、接着剤等により着座部に一体に形成される ため、サイド部と着座部との境界部分に応力集中が発生しない。 Since the side portion is integrally formed with the seat portion in the slit portion by an adhesive or the like, stress concentration does not occur at the boundary portion between the side portion and the seat portion.

【0009】[0009]

【実施例】【Example】

以下、本考案の実施例を、図1乃至図6に基づいて説明する。 図1、2は、本考案の第1実施例を示し、前記図9に示すが如く、従来と同一 の方法で、発泡成形したパッド(P)を使用し、その高硬度パッドからなるサイ ド部(2)と低硬度パッドからなる着座部(1)との間のスリット(4)が拡開 するように、サイド部(2)を着座部(1)に対して外方に加圧する。この状態 で、スリット(4)を形成する隔壁(42)(43)に接着剤を塗布する。然る 後、スリット(4)が閉鎖するように、サイド部(2)を着座部(1)方向に加 圧して、両隔壁(42)(43)を一体に接着する。 これにより、前記スリット(4)は閉口され、図2に示すパッド(P)が得ら れる。 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2 show a first embodiment of the present invention, and as shown in FIG. 9, a pad (P) formed by foam molding is used in the same manner as the conventional method, and a side made of a high hardness pad is used. The side part (2) is pressed outwardly against the seating part (1) so that the slit (4) between the part (2) and the seating part (1) made of a low hardness pad widens. In this state, the adhesive is applied to the partition walls (42) and (43) forming the slit (4). Then, the side portion (2) is pressed toward the seating portion (1) so that the slit (4) is closed, and the partition walls (42) and (43) are bonded together. As a result, the slit (4) is closed and the pad (P) shown in FIG. 2 is obtained.

【0010】 図3乃至図6は、本考案の第2実施例を示し、斯かる実施例は、前記スリット (4)の隔壁(42)(43)に相互に係合する面状ファスナーなどの連結部材 (42A)(43A)を設けて、サイド部(2)と着座部(1)とをスリット( 4)部分で一体に形成したものである。FIGS. 3 to 6 show a second embodiment of the present invention, which relates to a planar fastener or the like which is engaged with the partition walls (42) (43) of the slit (4). The connecting member (42A) (43A) is provided, and the side portion (2) and the seating portion (1) are integrally formed in the slit (4) portion.

【0011】 以上の連結部材(42A)(43A)は、図5、6に示すように、成形下型( 5)の仕切壁(4A)における左右両面に固定し、前記従来方法と同一方法で、 サイド部(2)と着座部(1)とを成形する。これにより、スリット(4)の隔 壁(42)(43)に連結部材(42A)(43A)が一体に固定される。 この連結部材(42A)(43A)をパッドを発泡成形後、相互に係合するこ とにより、図3、4に示すように、スリット(4)の両側の着座部(1)とサイ ド部(2)とが一体に連結される。 図5、6において、図9と同一符号は同一部材を示し、その説明を省略する。As shown in FIGS. 5 and 6, the above-mentioned connecting members (42A) and (43A) are fixed to both left and right sides of the partition wall (4A) of the lower molding die (5), and the same method as the conventional method is used. The side part (2) and the seating part (1) are molded. As a result, the connecting members (42A) (43A) are integrally fixed to the partition walls (42) (43) of the slit (4). By foaming the pads of the connecting members (42A) and (43A) and then engaging them with each other, as shown in FIGS. 3 and 4, the seat portion (1) and the side portion on both sides of the slit (4) are formed. (2) is integrally connected. 5 and 6, the same reference numerals as those in FIG. 9 indicate the same members, and the description thereof will be omitted.

【0012】[0012]

【考案の効果】[Effect of device]

本考案は成形型の仕切壁によって形成されるスリットが接着剤、相互に係合す る連結部材によって閉口されて、スリットによって分離されていた着座部とサイ ド部とが一体になる。 従って、応力が前記従来品の如く、スリットの下方に集中することがないため 、サイド部と着座部との間におけるパッドに割れが発生せず、シートの長期使用 によっても、サイド部が着座部から分離することがない。 また、従来品を単に接着等することにより、従来品の不具合を除去でき、特別 の設置、装置…等を必要としないため、低原価で提供できる。 In the present invention, the slit formed by the partition wall of the mold is closed by an adhesive and a coupling member that engages with each other, and the seat portion and the side portion separated by the slit are integrated. Therefore, unlike the conventional products, the stress does not concentrate below the slit, so that the pad does not crack between the side portion and the seating portion, and the side portion does not have a seating portion even when the seat is used for a long period of time. Never separated from. In addition, the conventional product can be provided at a low cost by simply adhering the conventional product to eliminate defects of the conventional product and without requiring special installation, equipment or the like.
