Description

本発明は、自動車用シートなどの車両用シートにおいてクッション材として用いられるクッションパッドに関するものである。   The present invention relates to a cushion pad used as a cushion material in a vehicle seat such as an automobile seat.

一般に、自動車の座席(シート)においてクッション材として用いられるクッションパッドは、軟質ポリウレタンフォームなどの弾力性のある軟質フォームからなり、所定形状の成形型内に発泡原液を注入し、発泡充填させることで成形されている(例えば、下記特許文献1,2参照)。   In general, a cushion pad used as a cushioning material in an automobile seat (seat) is made of a flexible flexible foam such as a flexible polyurethane foam. By injecting a foaming stock solution into a predetermined mold, the foam pad is filled with foam. It is molded (see, for example, Patent Documents 1 and 2 below).

ところで、車両用シートにはアームレスト付シートがあり、該シートのシートバックに用いられるクッションパッドとして、背もたれ部を構成するパッド本体部と、その側部に設けられて前面にアームレストを回動自在に収納する収納凹部を備えるアームレスト部とからなるものが知られている(下記特許文献3参照)。
特開2006−416号公報 特開2006−1213号公報 特開2001−258677号公報
By the way, the vehicle seat has a seat with an armrest, and as a cushion pad used for the seat back of the seat, the pad main body portion constituting the backrest portion and the armrest on the front side thereof can be rotated. What consists of an armrest part provided with the accommodation recessed part to accommodate is known (refer the following patent document 3).
JP 2006-416 A JP 2006-1213 A JP 2001-258777 A

上記のようなアームレスト付シートのクッションパッドにおいては、前記パッド本体部とアームレスト部との境界部に、シートバックを可倒式にするためのヒンジ部を受け入れるための切り欠き部26(図6参照)が設けられることがある。かかる切り欠き部が設けられた場合、アームレスト収納凹部6の下側の厚肉状の張り出し部22とパッド本体部12とが薄肉状の繋ぎ部28で接続された形状となる。   In the cushion pad of the seat with the armrest as described above, the notch portion 26 (see FIG. 6) for receiving the hinge portion for making the seat back collapsible at the boundary portion between the pad main body portion and the armrest portion. ) May be provided. When such a notch is provided, the thick overhanging portion 22 on the lower side of the armrest housing recess 6 and the pad main body 12 are connected by a thin connecting portion 28.

このような薄肉状の繋ぎ部で接続された形状の場合、成形型内において、厚肉部であるパッド本体部と張り出し部を成形するための比較的広い2箇所のキャビティの間が、繋ぎ部を成形するための狭い流路(即ち、絞られた流路)を介して接続されることになる。そのため、発泡充填時に、該狭い流路での発泡原液の流動が激しく、その周辺部の成形性に影響を与え、発泡セルの崩壊(コラプス)によるヒケや、エア溜まりなどが発生するおそれがある。   In the case of a shape connected by such thin-walled connecting portions, the connecting portion is formed between two relatively wide cavities for forming the pad main body portion that is a thick-walled portion and the overhang portion in the molding die. Are connected via a narrow flow path (that is, a narrowed flow path). Therefore, during foam filling, the flow of the foaming stock solution in the narrow flow path is intense, which affects the moldability of the peripheral portion, and there is a risk that sink due to collapse (collapse) of foamed cells or air accumulation may occur. .

本発明は、以上の点に鑑みてなされたものであり、アームレスト付シートのクッションパッドにおける成形性の向上を目的とする。   This invention is made | formed in view of the above point, and aims at the improvement of the moldability in the cushion pad of a seat with an armrest.

本発明の請求項1に係るクッションパッドは、背もたれ部を構成するパッド本体部と、該パッド本体部の側部に連結一体化されるとともに前面にアームレストを回動自在に収納する収納凹部が設けられたアームレスト部と、を成形型内における発泡原料の発泡充填により成形してなるクッションパッドであって、前記収納凹部の下側の厚肉状の張り出し部に隣接されて、前記アームレスト部と前記パッド本体部との境界部に、下方に向けて開かれた切り欠き部が設けられ、該切り欠き部により前記張り出し部と前記パッド本体部とが薄肉状の繋ぎ部で接続されるよう形成されており、前記張り出し部の裏面側にコア抜き凹部が設けられたものである。   A cushion pad according to claim 1 of the present invention is provided with a pad main body portion constituting a backrest portion, and a storage concave portion that is connected and integrated with a side portion of the pad main body portion and rotatably stores an armrest on the front surface. A cushion pad formed by foam filling of a foaming raw material in a molding die, adjacent to a thick overhanging portion on the lower side of the storage recess, and the armrest portion and the A notch portion opened downward is provided at a boundary portion with the pad main body portion, and the overhang portion and the pad main body portion are formed to be connected by a thin-walled connecting portion by the notch portion. And a cored recess is provided on the back side of the overhang.

上記構成によれば、厚肉状の張り出し部の裏面にコア抜き凹部を設けたことにより、アームレスト収納凹部の下部の張り出し部での容積が低減される。そのため、発泡充填時に、パッド本体部と張り出し部との間を繋ぐ繋ぎ部での発泡原液の流動が抑えられ、成形性が改善される。また、この場合、コア抜き分だけ成形後のクッションパッドの容積が低減されるので、その分、軽量化が図られ、コストダウンにもつながる。   According to the said structure, the volume in the overhang | projection part of the lower part of an armrest accommodation recessed part is reduced by providing the core extraction recessed part in the back surface of a thick-walled overhang | projection part. Therefore, at the time of foam filling, the flow of the foaming stock solution at the joint portion connecting the pad main body portion and the overhang portion is suppressed, and the moldability is improved. In this case, since the volume of the cushion pad after molding is reduced by the amount of core removal, the weight can be reduced by that amount, which leads to cost reduction.

本発明の請求項2に係るクッションパッドは、背もたれ部を構成するパッド本体部と、該パッド本体部の側部に連結一体化されるとともに前面にアームレストを回動自在に収納する収納凹部が設けられたアームレスト部と、を備えてなり、前記収納凹部の下側の厚肉状の張り出し部に隣接されて、前記アームレスト部と前記パッド本体部との境界部に、下方に向けて開かれた切り欠き部が設けられ、該切り欠き部により前記張り出し部と前記パッド本体部とが薄肉状の繋ぎ部で接続されるよう形成されたクッションパッドであって、前記切り欠き部の少なくとも上部を、前記張り出し部と該張り出し部に対向する前記パッド本体部の下端部とを連結する連結部にて塞いだ状態で、前記パッド本体部と前記アームレスト部を成形型内における発泡原料の発泡充填により一体に発泡成形し、該連結部を発泡成形後に切除することで前記切り欠き部を形成してなるものである。   A cushion pad according to claim 2 of the present invention is provided with a pad main body portion constituting a backrest portion, and a storage concave portion that is connected and integrated with a side portion of the pad main body portion and that rotatably stores an armrest on the front surface. An armrest portion formed on the lower side of the housing recess, adjacent to the thickened overhanging portion, and opened downward at the boundary between the armrest portion and the pad main body portion. A notched portion is a cushion pad formed so that the notched portion and the overhanging portion and the pad main body portion are connected by a thin-walled connecting portion, and at least an upper portion of the notched portion, The pad body portion and the armrest portion are formed in the mold in a state where the pad body portion and the lower end portion of the pad body portion facing the overhang portion are closed by a connecting portion. Foamed integrally molded by foam filling the raw material, those obtained by forming the cutout portion by excising the connecting portion after the foam molding.

上記構成によれば、薄肉状の繋ぎ部を形成する切り欠き部を連結部にて塞いだ形状に発泡成形するので、厚肉状の張り出し部とパッド本体部を成形する2つのキャビティ間を繋ぐ繋ぎ部の流路が該連結部により拡大されて、発泡原液の流動が抑えられ、成形性が改善される。   According to the above configuration, since the notched portion forming the thin-walled connecting portion is foam-molded into a shape in which the notched portion is closed by the connecting portion, the thick-walled overhanging portion and the two cavities for forming the pad main body portion are connected. The flow path of the connecting portion is expanded by the connecting portion, the flow of the foaming stock solution is suppressed, and the moldability is improved.

上記のように本発明によれば、パッド本体部とアームレスト部とを一体に発泡成形したものでありながら、ヒケやエア溜まりが抑制された成形性に優れるクッションパッドが得られる。   As described above, according to the present invention, it is possible to obtain a cushion pad excellent in moldability in which sink and air accumulation are suppressed while the pad main body portion and the armrest portion are integrally foam-molded.

以下、本発明の実施形態について図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(第1実施形態)
図1は第1実施形態に係るクッションパッド10の正面図、図2は同クッションパッド10の裏面図である。
(First embodiment)
FIG. 1 is a front view of the cushion pad 10 according to the first embodiment, and FIG. 2 is a rear view of the cushion pad 10.

このクッションパッド10は、図6に示すような自動車のリアシート1を構成するシートバック2に用いられる高弾性の軟質ポリウレタンフォームからなるクッション材である。シートバック2は、左右の着座部3,4の間にアームレスト5を備え、アームレスト5は、図6に示す前倒しされた使用状態と、収納凹部6内に押し込まれた縦姿勢の収納状態とに切り替えることができるように回動自在に設けられている。本実施形態が対象とするクッションパッドは、上記アームレスト5を収納する収容凹部を一体に備えたクッションパッド10であり、図6において中央部を含む右側のシートバック部分に用いられるものである。   The cushion pad 10 is a cushion material made of a highly elastic flexible polyurethane foam used for a seat back 2 constituting a rear seat 1 of an automobile as shown in FIG. The seat back 2 is provided with an armrest 5 between the left and right seating portions 3 and 4, and the armrest 5 is in a forward use state shown in FIG. 6 and a vertically stored state pushed into the storage recess 6. It is rotatably provided so that it can be switched. The cushion pad targeted by the present embodiment is a cushion pad 10 that is integrally provided with a housing recess that houses the armrest 5, and is used for the right seat back portion including the center portion in FIG.

図1に示すように、クッションパッド10は、着座部4の背もたれ部を構成するパッド本体部12と、その車両中央側の側部12Aに連結一体化されたアームレスト部14とを備えてなる。アームレスト部14は、その前面14Aに、アームレスト5を回動自在に収納する収納凹部16を備え、該収納凹部16は、アームレスト部14の下部を除く全体に矩形状に形成されている。そして、収納凹部16内における下端部の両側部には、アームレスト5を回動可能に支持するためのヒンジ用開口部18,20が設けられている。   As shown in FIG. 1, the cushion pad 10 includes a pad main body portion 12 that constitutes a backrest portion of the seating portion 4 and an armrest portion 14 that is connected and integrated with a side portion 12A on the vehicle center side. The armrest portion 14 includes a storage recess 16 that rotatably stores the armrest 5 on the front surface 14 </ b> A, and the storage recess 16 is formed in a rectangular shape except for the lower portion of the armrest portion 14. And the opening parts 18 and 20 for hinges for supporting the armrest 5 so that rotation is possible are provided in the both sides of the lower end part in the storage recessed part 16. As shown in FIG.

アームレスト部14における収納凹部16の下側部分は、図3にも示されるように、パッド本体部12の前面と略面一になるように、前方に張り出した張り出し部22として構成されており、すなわち、収納凹部16が設けられた薄肉状部分に対して厚肉状に形成されている。   As shown in FIG. 3, the lower portion of the storage recess 16 in the armrest portion 14 is configured as a protruding portion 22 that protrudes forward so as to be substantially flush with the front surface of the pad main body portion 12. That is, it is formed thick with respect to the thin-walled portion provided with the storage recess 16.

アームレスト部14とパッド本体部12との境界部24における下端部には、上記張り出し部22に隣接させて切り欠き部26が設けられている。この切り欠き部26は、シートバック2を倒すヒンジ部を受け入れるために、下方に向けて開かれた平面視コの字状に形成されている。また、切り欠き部26の高さ(シートバック2の上下方向における切り欠き部の長さ)は、上記張り出し部22の高さと略同じ寸法に設定されている。   A notch 26 is provided at a lower end portion of the boundary portion 24 between the armrest portion 14 and the pad main body portion 12 so as to be adjacent to the protruding portion 22. The notch 26 is formed in a U-shape in a plan view that is opened downward to receive a hinge part that tilts the seat back 2. Further, the height of the notch 26 (the length of the notch in the vertical direction of the seat back 2) is set to be approximately the same as the height of the overhanging portion 22.

上記のように切り欠き部26が設けられたことにより、張り出し部22とパッド本体部12とは、薄肉状の繋ぎ部28で接続された形状となっている。より詳細には、厚肉状のパッド本体部12と張り出し部22の隣接する角部同士が、絞り形状となる幅狭の繋ぎ部28を介して接続されている。   By providing the cutout portion 26 as described above, the overhang portion 22 and the pad main body portion 12 are connected by the thin-walled connecting portion 28. More specifically, adjacent corners of the thick pad main body 12 and the overhanging portion 22 are connected to each other via a narrow connecting portion 28 having a drawing shape.

そして、図2,4に示すように、本実施形態では、上記厚肉状の張り出し部22の裏面22Aに、コア抜き凹部30が設けられている。コア抜き凹部30は、張り出し部22の中央部を含む略全域にわたって、裏面側から四角錐台状に陥没する肉抜き凹所として設けられており、これにより、張り出し部22は、正面側から見た外形形状の変更を伴うことなく、比較的薄肉状に形成されている。   As shown in FIGS. 2 and 4, in this embodiment, a cored recess 30 is provided on the back surface 22 </ b> A of the thick overhang 22. The cored concave part 30 is provided as a hollow part recessed into a quadrangular pyramid shape from the back side over substantially the entire region including the center part of the projecting part 22, whereby the projecting part 22 is viewed from the front side. It is formed in a relatively thin shape without changing the outer shape.

クッションパッド10は、図5に示すように、パッドの正面側を成形する凹状の下型50と、パッドの裏面側を成形する上型52と、を備える成形型54を用いて、発泡成形により製造される。すなわち、下型50に、ポリウレタン原液などの発泡原液56を供給し、上型52を被せて型閉めして、これにより形成される成形型54のキャビティ(発泡空間)58内で発泡原液56を発泡充填させることで、クッションパッド10が発泡成形され、成形後、脱型することにより、クッションパッド10が得られる。   As shown in FIG. 5, the cushion pad 10 is formed by foam molding using a molding die 54 that includes a concave lower mold 50 that molds the front side of the pad and an upper mold 52 that molds the back side of the pad. Manufactured. That is, a foaming stock solution 56 such as a polyurethane stock solution is supplied to the lower mold 50, and the upper mold 52 is covered and the mold is closed, and the foaming stock solution 56 is formed in a cavity (foaming space) 58 of the mold 54 formed thereby. The cushion pad 10 is foam-molded by foam filling, and the cushion pad 10 is obtained by removing the mold after molding.

かかる発泡成形時、上記クッションパッド10においては、アームレスト部14の下端部の張り出し部22とパッド本体部12とが薄肉状の繋ぎ部28で接続されており、そのため、パッド本体部12を成形するための広いキャビティがこの繋ぎ部28で急激に絞られている。また特に本実施形態の場合、収納凹部16内に設けられた中央側のヒンジ用開口20により、この繋ぎ部28近傍における発泡原液56の流路が一層狭められているが、上記張り出し部22の裏面にコア抜き凹部30を設けたことにより、該張り出し部22を成形するためのキャビティの容積が大幅に低減されている。そのため、発泡充填時に、パッド本体部12と張り出し部22との間を繋ぐ繋ぎ部28での発泡原液56の激しい流動が抑えられ、成形性が改善される。   At the time of foam molding, in the cushion pad 10, the overhanging portion 22 at the lower end portion of the armrest portion 14 and the pad main body portion 12 are connected by the thin-walled connecting portion 28, and thus the pad main body portion 12 is molded. A wide cavity for this purpose is abruptly squeezed by the connecting portion 28. In particular, in the case of the present embodiment, the flow path of the foaming stock solution 56 in the vicinity of the joint portion 28 is further narrowed by the hinge opening 20 on the central side provided in the housing recess 16. By providing the cored recess 30 on the back surface, the volume of the cavity for forming the overhanging portion 22 is greatly reduced. Therefore, at the time of foam filling, the intense flow of the foaming stock solution 56 at the connecting portion 28 connecting the pad main body portion 12 and the overhang portion 22 is suppressed, and the moldability is improved.

よって、本実施形態によれば、上記繋ぎ部28での激しい液流動に起因するその周辺部での成形性不良が改善され、発泡セルの崩壊(コラプス)によるヒケや、エア溜まりなどが抑制される。また、本実施形態によれば、コア抜きした分だけ成形後のクッションパッド10の容積が低減されるので、その分、軽量化が図られ、コストダウンにもつながる。   Therefore, according to the present embodiment, the formability failure in the peripheral portion due to the intense liquid flow in the connecting portion 28 is improved, and sink marks due to collapse (collapse) of foamed cells, air accumulation, and the like are suppressed. The Moreover, according to this embodiment, since the volume of the cushion pad 10 after shaping | molding is reduced by the part which removed the core, the weight reduction is achieved by that much and it leads also to a cost reduction.

なお、このようにして成形されたクッションパッド10は、シートバックフレームに組み込まれ、表面に表皮が被せられ、更にアームレスト5を装着することにより、リアシート1として構成される。   The cushion pad 10 molded in this way is assembled as a rear seat 1 by being incorporated in a seat back frame, covered with a skin, and further equipped with an armrest 5.

(第2実施形態)
次に、第2実施形態に係るクッションパッド10Aについて図7,8に基づいて説明する。第2実施形態のクッションパッド10Aは、上記切り欠き部26を塞いだ状態に発泡成形し、発泡成形後に上記塞いだ部分を切除することで切り欠き部26を所定形状に形成することを特徴とするものである。
(Second Embodiment)
Next, a cushion pad 10A according to a second embodiment will be described with reference to FIGS. The cushion pad 10A of the second embodiment is characterized in that the notched portion 26 is foam-molded in a closed state, and the notched portion 26 is formed in a predetermined shape by excising the closed portion after foam molding. To do.

詳細には、図7に示す発泡成形後の状態では、切り欠き部26は、その下端部を除いて連結部32により塞がれている。連結部32は、図8にも示されるように、張り出し部22の側面22Bと、これに対向するパッド本体部12の下端部34の側面34Aとを連結するように設けられており、これにより、張り出し部22とパッド本体部12とを繋ぐ上記繋ぎ部28での繋がり面積が大きく確保されている。   Specifically, in the state after foam molding shown in FIG. 7, the cutout portion 26 is closed by the connecting portion 32 except for its lower end portion. As shown in FIG. 8, the connecting portion 32 is provided so as to connect the side surface 22B of the overhang portion 22 and the side surface 34A of the lower end portion 34 of the pad main body portion 12 opposed thereto. In addition, a large connection area is secured at the connecting portion 28 that connects the overhang portion 22 and the pad main body portion 12.

このように、薄肉状の繋ぎ部28を形成する切り欠き部26を連結部32にて塞いだ形状に発泡成形するので、厚肉状の張り出し部22とパッド本体部12を成形する2つのキャビティ間を繋ぐ繋ぎ部28の流路が該連結部32により拡大されるので、発泡原液の激しい流動が抑えられ、成形性が改善される。   In this way, since the notched portion 26 forming the thin-walled connecting portion 28 is foam-molded into a shape in which the connecting portion 32 is closed, the two cavities for forming the thick-walled overhanging portion 22 and the pad main body portion 12 are formed. Since the flow path of the connecting portion 28 connecting the two is expanded by the connecting portion 32, the intense flow of the foaming stock solution is suppressed, and the moldability is improved.

なお、この例では、張り出し部22の裏面側に、第1実施形態のようなコア抜き凹部30は設けられていないが、上記連結部32により、同様に発泡原液の激しい流動が抑えられる。   In this example, the cored recess 30 as in the first embodiment is not provided on the back surface side of the overhanging portion 22, but the connecting portion 32 similarly suppresses the intense flow of the foaming stock solution.

上記連結部32は、発泡成形後に、カッターなどの切断手段を用いて切り取られ、これにより、切り欠き部26が形成されて(図3と同様な状態)、所定形状のクッションパッド10Aが得られる。かかる切断時における作業性の観点より、上記切り欠き部26を完全に塞いでしまうよりも、下端部を除いて塞ぐことが好ましく、より詳細には、繋ぎ部28近傍の切り欠き部26上部のみを塞ぐことが好ましい。   After the foam molding, the connecting portion 32 is cut using a cutting means such as a cutter, whereby a cutout portion 26 is formed (the same state as in FIG. 3), and a cushion pad 10A having a predetermined shape is obtained. . From the viewpoint of workability at the time of cutting, it is preferable to close the cutout portion 26 except for the lower end portion, rather than completely closing the cutout portion 26. More specifically, only the upper portion of the cutout portion 26 in the vicinity of the joint portion 28 is covered. It is preferable to block.

その他の構成は、第1実施形態と同様であり、同様の作用効果が奏される。   Other configurations are the same as those of the first embodiment, and the same operational effects are achieved.

本発明は、自動車シートを始めとする各種のアームレストを備えるシートのクッション材として利用することができる   INDUSTRIAL APPLICABILITY The present invention can be used as a cushion material for seats including various armrests including automobile seats.
