Description

本発明は自動車用シートなどの車両用シートにおけるシートクッション構造に関する。   The present invention relates to a seat cushion structure in a vehicle seat such as an automobile seat.

従来の一般的な自動車用シートのシートクッションは、シートクッション自体の外側に、シートクッションと別体の合成樹脂製フィニッシャを取付けて、シートクッションの側方より露出するリクライニングデバイス、スライドレール、リフターなどの機構部品を被覆している(例えば、特開２００６−８８９４３号公報)。   Conventional seat cushions for general automobile seats are equipped with a synthetic resin finisher that is separate from the seat cushion itself, and a reclining device, slide rail, lifter, etc. exposed from the side of the seat cushion. These mechanical parts are covered (for example, JP-A-2006-88943).

特開２００６−８８９４３号公報JP 2006-88943 A

従って、従来のシートクッションはフィニッシャによって機構部品を被覆してシートクッションの外観品質を向上させているが、フィニッシャは合成樹脂で、シートクッションの外面を構成する布などの柔軟部材製トリムカバーに対して別体感が強く、デザイン上の制約を受けやすい。   Therefore, the conventional seat cushion covers the mechanical parts with the finisher to improve the appearance quality of the seat cushion, but the finisher is made of synthetic resin and is against the trim cover made of flexible material such as cloth that forms the outer surface of the seat cushion. It has a different feeling and is subject to design constraints.

また、フィニッシャはピン、フック、止めねじ等によってシートクッションのフレーム、スライドレールのアッパーレールなどに取付ける必要があり、その取付に工数を要する不具合があった。   Further, the finisher needs to be attached to the frame of the seat cushion, the upper rail of the slide rail, etc. by pins, hooks, set screws, etc., and there is a problem that requires a lot of man-hours for the attachment.

そこで、本発明はシートクッションの側方下部側に配設する前記合成樹脂製フィニッシャによる不具合を除去することを目的とする。   Therefore, an object of the present invention is to eliminate problems caused by the synthetic resin finisher disposed on the side lower side of the seat cushion.

以上の目的を達成するための本発明に係る車両用シートのシートバック構造は、シートクッションの側面を構成するトリムカバーのサイド部と、シートクッション側部の外方且つ下方より露出する機構部品をカバーするフィニッシャ部とを、合成樹脂を含浸させて凹凸状に成形した成形不織布で、一体に成形してなることを特徴とする。   In order to achieve the above object, a seat back structure for a vehicle seat according to the present invention includes a side portion of a trim cover that constitutes a side surface of a seat cushion, and a mechanism component that is exposed from the outside and below the side portion of the seat cushion. The finisher portion to be covered is formed integrally with a molded non-woven fabric impregnated with a synthetic resin and formed into an uneven shape.

また、前記成形不織布の代わりに、ショア硬さ５０程度又はそれ以下の硬さを有し縫合可能な素材を使用してもよい。   Moreover, you may use the raw material which has the hardness of about 50 or less Shore hardness, and can be sewn instead of the said shaping | molding nonwoven fabric.

また、前記トリムカバーのサイド部に相当する前記成形不織布又は前記素材のトリムカバー部に、凹溝又は凸条の撓み吸収部を設けるようにするのが好ましい。   Moreover, it is preferable to provide a groove or a ridge-shaped deflection absorbing portion in the molded nonwoven fabric or the trim cover portion of the material corresponding to the side portion of the trim cover.

本発明によれば、従来の合成樹脂製フィニッシャを使用しないため、従来のフィニッシャ取付作業が不要となる。加えて、シートクッションのトリムカバーのサイド部とフィニッシャ部とが一体に前記成形不織布又は前記素材で形成されているため、デザイン上の一体感があり、デザインのバリエーションが期待できる。   According to the present invention, since the conventional synthetic resin finisher is not used, the conventional finisher mounting operation becomes unnecessary. In addition, since the side portion and the finisher portion of the trim cover of the seat cushion are integrally formed of the molded nonwoven fabric or the material, there is a sense of unity in design and design variations can be expected.

加えて、前記成形不織布又は素材のトリムカバー部に撓み吸収部を設けることにより、シートクッションに加わる撓みが吸収され、前記成形不織布又は前記素材のフィニッシャ部の変形を防止することができる。   In addition, by providing a bending absorbing portion in the trim cover portion of the molded nonwoven fabric or material, the bending applied to the seat cushion is absorbed, and deformation of the molded nonwoven fabric or the finisher portion of the material can be prevented.

以下、本発明の一実施例を図面に基づいて説明する。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

図１は本発明に係るシートクッション構造の自動車用シートを示し、図中Ａ、Ａは前記成形不織布、ＢはシートクッションＳＣのトリムカバーのメイン部を各々示す。   FIG. 1 shows an automobile seat having a seat cushion structure according to the present invention, in which A and A show the molded nonwoven fabric, and B shows a main part of a trim cover of the seat cushion SC.

成形不織布Ａ、Ａは、例えば、合成樹脂を含浸させて凹凸状にプレスなどで成形した成形不織布を使用している。
この成形不織布Ａ、Ａは、図２に示すように、合成樹脂を含浸させて凹凸状にプレスなどで成形したもので、硬質且つ保形性を有するように、例えば実開平７−１５４４８号に開示されている材質、成形方法によって成形したものを使用する。 As the molded nonwoven fabrics A and A, for example, molded nonwoven fabrics that are impregnated with a synthetic resin and formed into a concavo-convex shape with a press or the like are used.
As shown in FIG. 2, the molded nonwoven fabrics A and A are impregnated with a synthetic resin and molded into a concavo-convex shape with a press or the like. For example, Japanese Utility Model Laid-Open No. 7-15448 A material molded by the disclosed material and molding method is used.

この成形不織布Ａ、ＡはシートクッションＳＣの側面を構成するトリムカバーのサイド部に相当するトリムカバー部１と、このトリムカバー部１と一体でシートクッションＳＣ側部の外方且つ下方より露出するリクライニングデバイス、スライドレール、リフターなどの機構部品を被覆するフィニッシャ部２とから構成されている。   The molded non-woven fabrics A and A are exposed from the trim cover portion 1 corresponding to the side portion of the trim cover constituting the side surface of the seat cushion SC, and from the outside and the lower side of the side portion of the seat cushion SC integrally with the trim cover portion 1. The finisher unit 2 is configured to cover mechanical parts such as a reclining device, a slide rail, and a lifter.

以上のトリムカバー部１のトリムカバーのメイン部Ｂに臨む端末１２には、スライドファスナーの一方のファスナーチェン１３Ａが縫合され、他方のファスナーチェン１３Ｂは図３に示すようにメイン部Ｂに縫合されている。   One fastener chain 13A of the slide fastener is sewn to the terminal 12 facing the main part B of the trim cover 1 of the above trim cover part 1, and the other fastener chain 13B is sewn to the main part B as shown in FIG. ing.

なお、メイン部Ｂはモールド成形された発泡体製のパッド５の表面に接着等して固定されている。   The main part B is fixed to the surface of the molded foam pad 5 by bonding or the like.

従って、メイン部Ｂの左右に、スライドファスナーで成形不織布Ａのトリムカバー部１を連結することにより、前記パッド５は被覆される。なお、スライドファスナーの代わりにトリムカバー部１をメイン部Ｂに縫合して連結しても良い。   Therefore, the pad 5 is covered by connecting the trim cover portion 1 of the molded nonwoven fabric A to the left and right of the main portion B with slide fasteners. Instead of the slide fastener, the trim cover portion 1 may be sewn and connected to the main portion B.

そして、図示するこのトリムカバー部１には上下二段状に前後方向に向けて撓み吸収部１０、１１が設けている。従って、着座時などパッド５が荷重により撓み、それに追従してトリムカバー部１が撓むが、この撓みを,撓み吸収部１０，１１で吸収する。従って、フィニッシュ部２に前記撓みが伝達されないため、フィニッシュ部２が前記荷重によって変形しない。   The trim cover portion 1 shown in the figure is provided with bending absorbing portions 10 and 11 in the front and rear direction in two vertical stages. Therefore, the pad 5 bends due to a load, such as when seated, and the trim cover portion 1 bends following the load. The bending absorbing portions 10 and 11 absorb this bending. Accordingly, since the bending is not transmitted to the finish portion 2, the finish portion 2 is not deformed by the load.

図示する撓み吸収部１０、１１は内方に凹む凹溝からなるものであるが、この凹溝の代わりに外方に突出する凸条に形成しても良い。   Although the illustrated bending absorbing portions 10 and 11 are formed of concave grooves that are recessed inward, they may be formed as protruding ridges protruding outward instead of the concave grooves.

以上の成形不織布Ａのトリムカバー部１はその内側にフック、差し込みプレートなどを縫着して、フック等をシートクッションのフレーム６や、スライドレールのアッパーレール(不図示)などに固定するのが望ましい。   The trim cover portion 1 of the above molded nonwoven fabric A is sewn with hooks, insertion plates, and the like, and the hooks are fixed to the frame 6 of the seat cushion or the upper rail (not shown) of the slide rail. desirable.

成形不織布Ａのフィニッシャ部２は従来のフィニッシャと略同形状に、トリムカバー部１に対して外方に突出するように成形されている。   The finisher portion 2 of the molded non-woven fabric A is shaped so as to protrude outward with respect to the trim cover portion 1 in substantially the same shape as the conventional finisher.

そして、この成形不織布Ａは成形時に同時に装飾用の樹脂(ポリエステルなど)フィルムを成形不織布Ａの表面にラミネート加工するのが好ましく、斯様にラミネートすることにより、成形不織布Ａの表面が樹脂フィルムで被覆されるため、外観品質が良好になるし、成形不織布Ａの保形性を向上させることができる。   The molded non-woven fabric A is preferably laminated with a decorative resin (polyester or the like) film on the surface of the molded non-woven fabric A at the same time as the molding, and by laminating in this way, the surface of the molded non-woven fabric A is a resin film. Since it is coated, the appearance quality is improved, and the shape retention of the molded nonwoven fabric A can be improved.

図中２０はフィニッシャ部２のシートバックＳＢ傾動用リクライニングデバイス７等の操作部材３、４を収容する収容凹部で、操作部材の差込口３１、４１が開口されている。２１はフィニッシャ部２の上部突出部を示す。   In the drawing, reference numeral 20 denotes an accommodation recess for accommodating the operation members 3 and 4 such as the reclining device 7 for tilting the seat back SB of the finisher portion 2, and the operation member insertion ports 31 and 41 are opened. Reference numeral 21 denotes an upper projecting portion of the finisher portion 2.

なお、図示するものはメイン部Ｂの左右両側に、成形不織布Ａ、Ａを連結しているが、一側のみ成形不織布Ａを設け、他側はメイン部Ｂと同一の材質からトリムカバーで形成しても良い。   In the figure, the molded nonwoven fabrics A and A are connected to the left and right sides of the main part B, but the molded nonwoven fabric A is provided only on one side, and the other side is formed from the same material as the main part B with a trim cover. You may do it.

また、メイン部Ｂは従来この種のシートに使用されている織物地、合成樹脂製レザー、皮革などで形成されている。   The main part B is formed of a woven fabric, synthetic resin leather, leather, or the like conventionally used for this type of sheet.

また、この成形不織布Ａの代わりに、ショア硬さ５０程度又はそれ以下の硬さを有し縫合可能な素材で，前記トリムカバー部１、フィニッシャ部２、撓み吸収部１０、１１をプレスなどにより凹凸状に成形してもよい。
この素材は、例えば，保形性を有する合成樹脂材製プレートに合成皮革、フィルムなどを貼着したもので、その端末にスライドファスナーの一方のファスナーチェンなどが縫合可能なものを使用している。 Further, instead of the molded nonwoven fabric A, the trim cover portion 1, the finisher portion 2, and the bending absorbing portions 10 and 11 are made of a material having a shore hardness of about 50 or less and capable of being sewn. You may shape | mold in uneven | corrugated shape.
This material is made of, for example, a synthetic resin plate having a shape-retaining property, and synthetic leather, a film, etc., and a terminal that can be sewn with one fastener chain of a slide fastener. .

そして、前記トリムカバー部１と、フィニッシャ部２に相当する部分のショア硬さを変え、例えば、トリムカバー部１の硬さをフィニッシャ部２に対して柔らかにして、トリムカバー部１をより一層撓み易くしても良い。
また、前記素材を使用した場合には、その外面側の合成樹脂材製プレート又は合成皮革など装飾加工などして、保形性を向上させると共に外観品質を良好にすることができる。 Then, the shore hardness of the trim cover portion 1 and the portion corresponding to the finisher portion 2 is changed, for example, the hardness of the trim cover portion 1 is softened with respect to the finisher portion 2, and the trim cover portion 1 is further made It may be easy to bend.
Moreover, when the said raw material is used, decoration processing etc., such as the synthetic resin material plate or synthetic leather of the outer surface side, can improve a shape retention property and can make appearance quality favorable.

従って、前述の如く、成形不織布又は素材で、従来のトリムカバーのサイド部と合成樹脂製フィニッシャに相当する部分を一体に成形しているため、前記従来のフィニッシャが不要になり、しかも、フィニッシャ部２がトリムカバー部と一体化されているため、シートクッションとシートクッションの付属部材とのデザイン上の一体感があり、外観品質に優れたシートクッションを提供できる。   Therefore, as described above, since the side portion of the conventional trim cover and the portion corresponding to the synthetic resin finisher are integrally formed with the molded nonwoven fabric or material, the conventional finisher becomes unnecessary, and the finisher portion Since 2 is integrated with the trim cover part, there is a sense of unity in design between the seat cushion and the attached member of the seat cushion, and a seat cushion excellent in appearance quality can be provided.
