本考案は車両用のサイドサポート装置、詳しく
は、シートバツクの左右に設けられたサイドサポ
ート部を傾動させて乗員の背部から側部にかけて
の支持形状を調整する装置に関するものである。[Detailed description of the invention] The present invention relates to a side support device for a vehicle, and more specifically, to a device that adjusts the support shape from the back to the side of the occupant by tilting the side support portions provided on the left and right sides of the seat back. .
従来、この種の一般的な装置は、例えば実開昭
58−100666号に開示されたもののように「シート

に回動するように」構成されている。 Conventionally, this type of general equipment was developed by, for example,
58-100666, a pair of rotating shafts rotatably supported along both sides of a seat frame, and a spring member connected between the pair of rotating shafts. and a pair of side support members respectively fixed to the rotation shaft so as to protrude to the opposite side of the rotation shaft to which the spring material is connected, and when the spring material is pressed downward. The rotation shaft is configured to rotate in response to a pressing force, and the tips of the pair of side support members are rotated in a direction in which the ends of the pair of side support members approach each other.
ところが、上記の如き構成ではサイドサポート

ポート部にかけての座面が体形に沿つた曲面に形
成されない不具合があつた。 However, in the above configuration, since the fulcrum of the side support member that tilts the side support part is located at the rotation axis located below the boundary between the seat bag main body and the side support part, a constriction occurs at the boundary part, causing the seat back to tilt. There was a problem where the seat surface from the main body to the side support part was not formed into a curved surface that followed the body shape.
更に、サイドサポート部を支持させるサイド支
持部材がその構造からついて剛性の高いもので形
成されており、このことがより一層座面形状を体
形にそぐわないものにしている。 Furthermore, the side support members that support the side support portions are made of a highly rigid material due to their structure, which makes the shape of the seat surface even more unsuitable for the body shape.

ようにしたものである。 To achieve the above object, the present invention consists of a pair of left and right boards arranged on the left and right sides of the back frame, a spring material that can support the seat back pad main body arranged on both the left and right boards, and a spring material attached to the board. It consists of an elastic support member provided with a support point whose height can be adjusted freely, and a support plate made of an elastic plate of the side support pad, which is supported by the elastic support member and is integrally locked with the spring material, and which is made of an elastic plate of the side support pad. By adjusting the height of the support point of the support member, the support plate of the side support pad is tilted in a curved manner, and the left and right side support portions of the seat back are tilted.

Bracket 1 installed with a predetermined play
0, a crank 11 rotatably connected to the bracket 10, a link 12 rotatably connected to the crank 11, an arm rod 13 rotatably connected to the link 12, and a connection for fixing the arm rod 13. The lever 1 is composed of a shaft 14, an operating rod 15 fixed to the connecting shaft 14, a cam 16 for rotating the operating rod 15, a lever 18 fixed to the cam shaft 17 of the cam 16, etc.
8 rotates the cam 16, the cam 16 rotates the communication shaft 14 via the operating rod 15, and the rotation of this communication shaft 14 causes the arm rod 1 to rotate.
3. Adjust the height of the left and right elastic support members 2 from the base plate 1 via the link 12 and the crank 11. Specifically, the heights of the support points 2' of the left and right elastic support members 2 from the substrate 1 are adjusted in conjunction with each other (FIG. 2).
尚、左右の弾性支持部材２の支持点２′の高さ
調節は１つのレバー１８の操作で連動させて行な
うのが一般的であるが、左右を夫々独立させて行
なうようにしてもよい。 Although the height adjustment of the support points 2' of the left and right elastic support members 2 is generally performed in conjunction with the operation of one lever 18, it may be performed independently for the left and right parts.
次に、支持板３は合成樹脂または弾性に富んだ
金属によつて形成され、一端にフツク１９を形成
し、他端を所定形状に湾曲させて形成している。 Next, the support plate 3 is made of synthetic resin or highly elastic metal, and has a hook 19 formed at one end and curved at the other end into a predetermined shape.
また、フツク１９寄りの上面には表皮２０の吊
に込み用の係止片２１が突設され、湾曲部近傍の
裏面には掛止片２２が突設されている。 Further, a locking piece 21 for hanging the skin 20 is provided protruding from the upper surface near the hook 19, and a locking piece 22 is provided protruding from the back surface near the curved portion.
尚、２３は吊り込み部の湾曲を滑めらかにする
ための抜き孔であり、この滑めらかにする手段と

持する。また、シートバツクパツド本体７とサイ
ドサポートパツド２４との境界部２５において表
皮２０が係止片２１に吊り込まれる。 This support plate 3 locks a hook 19 to a spring member 8 that can support the seat back pad main body 7, and also loosely fits the support point 2' of the elastic support member 2 into a locking piece 22 on the back surface. The seat back pad main body 7 is supported by the hook 19 side, and the side support pad 24 is supported by the other part. Further, the outer skin 20 is suspended by the locking piece 21 at the boundary 25 between the seat back pad main body 7 and the side support pad 24.
このことから、サイドサポート部２６を傾動さ
せるにはレバー１８を回動し、弾性支持部材２の
支持点２′の高さを変えて行なう。 Therefore, in order to tilt the side support portion 26, the lever 18 is rotated to change the height of the support point 2' of the elastic support member 2.
つまり、支持点２′の高さが変わると支持板３
がフツク１９を支点として傾動し、サイドサポー
ト部２６を傾動させる。 In other words, if the height of the support point 2' changes, the support plate 3
is tilted using the hook 19 as a fulcrum, and the side support portion 26 is tilted.
この時、支持板３はその一端がフツク１９によ
つてスプリング材８に固定され回動しない。従つ

緩やかに湾曲して傾動するので、サイドサポート
パツド２４と一体となつてシートバツクパツド本
体７の側部が湾曲し、それらの境界部２５におい
てくびれが生じない。 At this time, one end of the support plate 3 is fixed to the spring member 8 by the hook 19 and does not rotate. Therefore, the support plate 3 gently curves and tilts from the hook 19 due to its elasticity, so that the sides of the seat back pad main body 7 are curved together with the side support pads 24, and the boundary portion 25 between them is bent. No constriction occurs.
また、基板１および支持板３がスプリング材８
に支持されているので両部材１，３がスプリング
材の撓みに追従し、かつ柔軟性に富んだ支持板３
が弾性支持部材２によつて支持されているので、
体形に沿つた滑らかな座面が得られる。 Further, the substrate 1 and the support plate 3 are connected to the spring material 8.
Since both members 1 and 3 follow the deflection of the spring material, the supporting plate 3 is highly flexible.
is supported by the elastic support member 2, so
Provides a smooth seating surface that follows your body shape.
本考案は叙上の桃如く構成したので以下の効果
を有する。 The present invention is constructed as described above, and has the following effects.
支持板は弾性を有し、一端はフツクによつてス
プリング材に固定され回動することがない。従つ
て、支持板の他端の支持点を弾性支持部材で変え

ので、着座者の体形に沿つた滑らかな座面が得ら
れる。そのため、精神的にも肉体的にも疲労の少
ないバケツトシートが得られる。 The support plate has elasticity, and one end is fixed to the spring material by a hook so that it does not rotate. Therefore, by changing the support point of the other end of the support plate with an elastic support member, the support plate is tilted in a curved manner using the hook as a fulcrum, so that a smooth seating surface that conforms to the body shape of the seated person can be obtained. Therefore, it is possible to obtain a bucket seat that is less tiring both mentally and physically.
また、支持板の肉厚の変化や各種リブの形成に
よつて、より高度の人間工学に則した完成度に高
いバケツトシートが得られる。 Furthermore, by changing the thickness of the support plate and forming various ribs, a bucket seat with a high degree of perfection and a higher degree of ergonomics can be obtained.
