Description
本発明は自動車用シートなどの車両用シートのシートクッションに関するものである。 The present invention relates to a seat cushion of a vehicle seat such as an automobile seat.
自動車用シートのシートクッションには、枠状のフレームと、発泡体製パッドを支持するパネルとを有するものがある。
Some seat cushions for automobile seats have a frame-like frame and a panel that supports a foam pad.
以上のパネルはその周囲をフレームに溶接したり、或いは、例えば特開２００７-９９１９５号公報に開示されているように、パネルをフレームにバネで吊り下げたものがある。
また、パネル全体をバネ性を有する部材で形成してたもの（例えば、特開２００５-２３７５１９号公報）…など種々のものが提案されている。
Some of the above panels are welded to the frame around the panel, or the panel is suspended from the frame by a spring as disclosed in, for example, Japanese Patent Application Laid-Open No. 2007-99195.
In addition, various types such as those in which the entire panel is formed of a member having a spring property (for example, JP-A-2005-237519) have been proposed.
以上のパネルをフレームに溶接したものはクッション性が不足するため、肉厚が厚いウレタンフォームなどのパッドを使用している。そのため、シートクッションの厚さが厚くなり車内のスペースが制約される。
Since the above panel welded to the frame lacks cushioning properties, a thick foam pad is used. Therefore, the thickness of the seat cushion is increased and the space in the vehicle is restricted.
一方、パネルをフレームにバネで吊り下げたものは、構造が複雑で組立工数が多くなる。
On the other hand, a panel suspended from a frame by a spring has a complicated structure and requires a large number of assembly steps.
また、パネル全体をバネ性を有する部材で形成したものは、例えば、乗員の大腿部を支持する前部など、クッション性が要求されない部分もクッション性を有し、着座性が損なわれる。 Moreover, what formed the whole panel with the member which has a spring property also has cushioning properties, such as the front part which supports a passenger | crew's thigh, and cushioning properties are required, and seating property is impaired.
そこで、本発明は以上の従来品の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 the problems of the conventional products described above.
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クッションはフレームと、発泡体製パッドを支持するパネルとを有する車両用シートのシートクッションにおいて、前記パネルは乗員の尻部を支持する尻部支持部と、この尻部支持部の前方に一体に設けて左右を前記フレームの左右に乗員の大腿部を支持する大腿部支持部と、前記尻部支持部の後方に延設して左右を左右のフレームに固設した後部連結部とから構成し、前記尻部支持部はその前方を左右のフレーム間に溶接すると共にビードによって形成した可撓部を設けて、尻部支持部に可撓性を付与してなることを特徴とする構成である。 In order to achieve the above object, a seat cushion for a vehicle seat according to the present invention is a seat cushion for a vehicle seat having a frame and a panel for supporting a foam pad, wherein the panel supports the butt of an occupant. A buttocks support portion, a thigh support portion that is integrally provided in front of the buttocks support portion to support the occupant's thigh on the left and right sides of the frame, and extends to the rear of the buttocks support portion. And a rear connecting portion fixed to the left and right frames, and the buttocks support portion is welded to the left and right frames and a flexible portion formed by beads is provided. It is the structure characterized by providing flexibility to a support part.
以上の尻部支持部の可撓部は、断面略Ｕ字状に形成した平面側コ字状の凹溝からなるビードで、このビードに囲まれた部分が尻部支持部の他の部分に対してより可撓するように構成し、そのビードに囲まれた部分に、凸条からなる補強ビードを設けて補強するのが好ましい。 The flexible part of the above-mentioned buttocks support part is a bead composed of a U-shaped groove on a flat side formed in a substantially U-shaped cross section, and the part surrounded by this bead is the other part of the buttocks support part On the other hand, it is preferable to reinforce by providing a reinforcing bead made of a protruding line at a portion surrounded by the bead.
従って、大腿部支持部は可撓性を有しないが、尻部支持部の全体、特に前記ビードに囲まれた部分は可撓性を有する。 Therefore, the thigh support portion does not have flexibility, but the entire buttocks support portion, in particular, the portion surrounded by the beads has flexibility.
本発明によれば、ばね部材を用いることなく、クッション性が要求されるパネルの尻部支持部のみが可撓性を有するので、パネル上に載置される発泡体製パッドの厚みを薄くでき、前記従来品の不具合を除去できる。 According to the present invention, the foam pad placed on the panel can be made thin because only the bottom support portion of the panel that requires cushioning has flexibility without using a spring member. , It is possible to eliminate the problems of the conventional products.
以下、本発明に係るシートクッションの好適な一実施例を図面に基づいて説明する。図中１はパネルで、板厚が例えば0.8ミリ程度の金属板をプレス成形して、大腿部支持部
１１、後部支持部１０、後部連結部１２が一体に形成されている。
Hereinafter, a preferred embodiment of a seat cushion according to the present invention will be described with reference to the drawings. In the figure, 1 is a panel, and a thigh support part 11, a rear support part 10, and a rear connection part 12 are integrally formed by press-molding a metal plate having a thickness of, for example, about 0.8 mm.
以上のパネル１は、大腿部支持部１１、後部支持部１２が、フレーム２の左右に溶接され、尻部支持部１０はその左右の端縁１００、１００が湾曲状に切欠されている。 In the panel 1 described above, the thigh support portion 11 and the rear support portion 12 are welded to the left and right of the frame 2, and the left and right edges 100, 100 of the butt support portion 10 are notched in a curved shape.
従って、尻部支持部１０の左右幅は、左右のフレーム２、２間の幅より狭く形成されているため、フレーム２、２に対して独立状で、フレーム２、２には固定せず、可撓性を有するように形成され、その前方である大腿部支持部１１をフレーム２、２に溶接している。
Therefore, since the left and right width of the bottom support portion 10 is formed narrower than the width between the left and right frames 2 and 2, it is independent of the frames 2 and 2 and is not fixed to the frames 2 and 2. The thigh support part 11 which is formed so as to have flexibility and is in front thereof is welded to the frames 2 and 2.
なお、フレーム２、２、２´は、後部開放状のコ字状に形成され、左右のフレーム２、２の後端側に、前記後部連結部１２の左右端部が溶接されている。この後部連結部１２は尻部支持部１０に対して上方に湾曲状に立ち上げた形状に形成されている。
The frames 2, 2, 2 ′ are formed in a U-shape that is open at the rear, and the left and right ends of the rear connecting portion 12 are welded to the rear ends of the left and right frames 2, 2. The rear connection portion 12 is formed in a shape that rises upward in a curved shape with respect to the buttocks support portion 10.
尻部支持部１０は図示するように、例えば５ミリ程度の深さを有する断面Ｕ字状の凹溝からなるビード１０Ａが、平面略コ字状に設けて、このビード１０Ａに囲まれた部分を可撓部イとし、この可撓部イは尻部支持部１０の他の部分に対して、可撓性に優れている。
As shown in the figure, the bottom support portion 10 is a portion surrounded by a bead 10A in which a bead 10A having a U-shaped groove having a depth of about 5 mm is provided in a substantially U-shaped plane. The flexible portion A is excellent in flexibility with respect to other portions of the butt support portion 10.
そして、ビード１０Ａに囲まれた部分には、突条の補強ビード１０Ｂ、１０Ｂを設けて補強している。図中、１０Ｃは、前記ビード１０Ａに囲まれた部分の可撓性を向上させるために開孔した通孔を示す。
And the reinforcement | strengthening beads 10B and 10B of a protrusion are provided in the part enclosed by bead 10A, and are reinforced. In the figure, reference numeral 10C denotes a through hole that is opened to improve the flexibility of the portion surrounded by the bead 10A.
大腿部支持部１１は図３、４に示すように、左右方向の中央部がフレーム２´方向に向けて高く傾斜するように、また、左右が中央部に対して高くなるように湾曲状に形成して、左、右をフレーム２、２上に溶接している。 As shown in FIGS. 3 and 4, the thigh support portion 11 is curved so that the central portion in the left-right direction is highly inclined toward the frame 2 ′ direction, and so that the left and right portions are higher than the central portion. The left and right are welded onto the frames 2 and 2.
なお、図示するものは、以上の左、右のフレーム２、２に、リフター用の平行リンク４０、４０を設け、この平行リンク４０、４０をスライドレールのアッパーレール４１に連結している。図中４２はスライドレールのロアレール、５０、５０はフレーム２、２の後端に取付けるシートバックのバックフレームを示す。
In the figure, the left and right frames 2 and 2 are provided with lifter parallel links 40 and 40, and the parallel links 40 and 40 are connected to an upper rail 41 of a slide rail. In the drawing, reference numeral 42 denotes a slide rail lower rail, and 50 and 50 denote back frames of seat backs attached to the rear ends of the frames 2 and 2.
以上の大腿部支持部１１、尻部支持部１０、後部連結部１２上には発泡体製パッド３が載置され、このパッド３は表皮材に被覆されてシートクッションを形成する。 The foam pad 3 is placed on the thigh support part 11, the buttocks support part 10 and the rear connection part 12, and the pad 3 is covered with a skin material to form a seat cushion.
このシートクッションに乗員が着座すると、パネル１の尻部支持部１０全体が可撓性を有し、更に、尻部支持部１０の中央に位置する可撓部イの可撓性が良いため、肉厚の薄い発泡体製パッド３を使用できる。 When an occupant sits on this seat cushion, the entire bottom part support part 10 of the panel 1 has flexibility, and further, the flexibility of the flexible part a located in the center of the bottom part support part 10 is good. A thin foam pad 3 can be used.
また、パネル２の大腿部支持部１１はフレーム２、２に溶接されているため、クッション性がなく、着座者の大腿部を確実に支持できる。 Moreover, since the thigh support part 11 of the panel 2 is welded to the frames 2 and 2, there is no cushioning property and the thigh part of the seated person can be reliably supported.
従って、パネル１のクッション性が要求される部分である尻部支持部１０のみがクッション性を有するので、パッド３全体の厚みを薄くでき、シートクッションの薄形化を図ることができるし、座り心地が良いシートクッションを提供できる。
Therefore, since only the bottom support portion 10 which is a portion where the cushioning property of the panel 1 is required has the cushioning property, the thickness of the entire pad 3 can be reduced, the seat cushion can be reduced in thickness, A comfortable seat cushion can be provided.
