Description

【０００１】
【発明の属する技術分野】
本発明は、自動車用シートなどの車両用シートの構造に関する。
【０００２】
【従来の技術】
従来の自動車用シート、例えばシートクッションは図４に示すようにモールド加工した発泡体製パッド１′にトリムカバー２０を接着して形成したものがある。
【０００３】
以上のトリムカバーは、シートクッションの着座面を形成する身頃部２０と、シートクッションの外側面を形成するまち部２１とを縫糸２２で接ぎ合わせ、その縫い代２０Ａ、２１Ａをパッド１′の上面イと側面ロとの境界であるパッド１′の上面イ外周囲に設けた収容凹部１１′内に収容して、縫い代２０Ａ、２１Ａによって、縫い代２０Ａ、２１Ａの外側部分が外方に突出することがないようにしている。
【０００４】
【発明が解決しようとする課題】
しかし、前記収容凹部１１′は、パッド１′の上面イ外周囲が曲線状に形成されているため、全体が曲線になる。また、縫い代２０Ａ、２１Ａが各々別体であるため、収容凹部１１′内において全体が一定の方向に向けて収容できない。
【０００５】
そのため、トリムカバー２０、２１の縫い代２０Ａ、２１Ａに対応する部分が蛇行したり、凹凸状になる。従って、シートクッションの着座面の外形形状を所期の設定したものに形成できない不具合があった。
【０００６】
そこで、本発明は斯様な従来品の不具合を解消することを目的とする。
【０００７】
【課題を解決するための手段】
以上の目的を達成するための本発明は、身頃部とまち部とを接ぎ合わせてなるトリムカバーと、このトリムカバーに被覆される発泡体製パッドとを有する車両用シートにおいて、前記パッドは、突出部と、前記身頃部とまち部とを接ぎ合わせた縫い代収納用の収納凹部と共に一体成形し、前記突出部はパッドの上面外周面に側面方向に突出成形し、前記収納凹部はパッドの側面に、前記突出部に上下方向に連続して成形してなる構成である。
【０００８】
以上のシートクッションＳＣ及びシートバックの着座面Ａ、Ａ′はトリムカバーの身頃部２０、外側面Ｂ、Ｂ′はまち部２１で各々形成されている。 身頃部２０はその大きさが従来の身頃部に対してやや大きく形成して周縁部２０′を延設して形成し、この周縁部２０′が図１、図２に示すようにシートクッションＳＣの外側面上部を形成している。
【０００９】
【発明の実施の形態】
以下、本発明の実施の一形態を図１乃至図３に基づいて説明する。
図１は本発明に係る車両用シートである自動車用シートを示し、図中ＳＣはシートクッション、ＳＢはシートバックを各々示す。
【００１０】
以上のシートクッションＳＣ及びシートバックの着座面Ａ、Ａ′はトリムカバーの身頃部２０、外側面Ｂ、Ｂ′はまち部２１で各々形成されている。
身頃部２０はその大きさが従来の身頃部に対してやや大きく形成して周縁部２０′を延設形成しし、この周縁部２０′が図１、図２に示すようにシートクッションＳＣの外側面上部を形成している。
【００１１】
トリムカバーの身頃部２０における周縁部２０′と前記まち部２１は、前記従来品と同様に縫糸２２で一体に接ぎ合わされており、その縫い代２０Ａ、２１Ａがパッド１の側面ロに設けた収容凹部１１内に収容されている。
【００１２】
パッド１はその上面イの外周囲に、側面ロ方向に突出する突出部１０が、前記収容凹部１１と共に一体にパッド発泡成形時に成形されている。
【００１３】
従って、突出部１０は図２に示すように前記身頃部２０の周縁部２０′によって被覆され、収容凹部１１は突出部１０に対して上下方向に連続して成形されている。
【００１４】
なお、トリムカバーの身頃部２０及び周縁部２０′はパッド１に接着剤で接着される。
【００１５】
【発明の効果】
本発明によれば、パッド１の上面イにおける外周囲に突出部を設け、トリムカバーの身頃部とまち部との接ぎ合わせ個所を収納する収納凹部をその下に設けているため、パッドの突出部の外形形状に沿ってトリムカバーの身頃部を被覆することができる。
【００１６】
従って、前記従来品の如く、トリムカバーの身頃部とまち部との接ぎ合わせ個所の外面が蛇行したりすることがない。そのため、シートの着座面の外周形状が常に一定で、外観品質に優れたシートを提供できる。

BACKGROUND OF THE INVENTION
The present invention relates to a structure of a vehicle seat such as an automobile seat.
[0002]
[Prior art]
A conventional automobile seat, for example, a seat cushion, is formed by adhering a trim cover 20 to a foam pad 1 'molded as shown in FIG.
[0003]
The trim cover described above has the body part 20 that forms the seating surface of the seat cushion and the town part 21 that forms the outer side surface of the seat cushion, which are brought into contact with the sewing thread 22 and the seam allowances 20A and 21A are connected to the upper surface of the pad 1 '. The outer portion of the seam allowances 20A and 21A may be protruded outward by the seam allowances 20A and 21A. I am trying not to.
[0004]
[Problems to be solved by the invention]
However, since the outer periphery of the upper surface of the pad 1 ′ is formed in a curved shape, the receiving recess 11 ′ is curved as a whole. Further, since the seams 20A and 21A are separate bodies, the whole cannot be accommodated in a certain direction in the accommodation recess 11 ′.
[0005]
Therefore, the portions of the trim covers 20 and 21 corresponding to the seam allowances 20A and 21A meander or become uneven. Therefore, there has been a problem that the outer shape of the seating surface of the seat cushion cannot be formed to a desired one.
[0006]
Therefore, an object of the present invention is to eliminate such problems of conventional products.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a vehicle seat having a trim cover formed by joining a body part and a town part, and a foam pad covered with the trim cover . The protrusion is integrally formed with a storage recess for storing a seam allowance in which the body part and the town part are joined, and the protrusion is protruded in the lateral direction on the outer peripheral surface of the pad, and the storage recess is a side surface of the pad. Furthermore, it is the structure formed by shape | molding continuously to the said protrusion part in the up-down direction.
[0008]
The seat cushions SC and seat back seating surfaces A and A ′ are formed by a trim cover body 20 and outer surfaces B and B ′ are formed by a gusset 21. The body part 20 is formed to be slightly larger than the conventional body part and is formed by extending a peripheral part 20 '. The peripheral part 20' is a seat cushion SC as shown in FIGS. The upper part of the outer surface is formed.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 shows an automobile seat which is a vehicle seat according to the present invention, in which SC denotes a seat cushion and SB denotes a seat back.
[0010]
The seat cushions SC and seat back seating surfaces A and A ′ are formed by a trim cover body 20 and outer surfaces B and B ′ are formed by a gusset 21.
The body part 20 is slightly larger in size than the conventional body part and has a peripheral part 20 'extending to form the peripheral part 20' as shown in FIGS. The upper part of the outer surface is formed.
[0011]
The peripheral edge portion 20 ′ and the gusset portion 21 of the trim cover body portion 20 are joined together by a sewing thread 22 as in the conventional product, and the seam allowances 20 </ b> A and 21 </ b> A are provided in the side recesses of the pad 1. 11.
[0012]
In the pad 1, a protruding portion 10 that protrudes in the direction of the side surface B is formed around the outer periphery of the upper surface A together with the housing recess 11 at the time of pad foam molding.
[0013]
Therefore, as shown in FIG. 2, the protruding portion 10 is covered with the peripheral edge portion 20 ′ of the body portion 20, and the accommodating recess 11 is continuously formed in the vertical direction with respect to the protruding portion 10.
[0014]
The body part 20 and the peripheral part 20 ′ of the trim cover are bonded to the pad 1 with an adhesive.
[0015]
【The invention's effect】
According to the present invention, the protrusion is provided on the outer periphery of the upper surface A of the pad 1 and the storage recess for storing the joint portion between the body part and the town part of the trim cover is provided below the protrusion. The body part of the trim cover can be covered along the outer shape of the part.
[0016]
Therefore, unlike the conventional product, the outer surface of the joint portion between the body part and the town part of the trim cover does not meander. Therefore, the outer peripheral shape of the seating surface of the seat is always constant, and a seat with excellent appearance quality can be provided.
