Description

本発明は、乗物用シートに関し、空気袋によりクッション長を変更可能とした乗物用シートに関する。   The present invention relates to a vehicle seat, and more particularly to a vehicle seat in which a cushion length can be changed by an air bag.

従来から着座者の体格や好みに応じてシートクッションの長さを調整可能なシートが知られている。下記特許文献１には、シートクッション前部のシートカバー付きパッドとフレームの間に空気袋を配置してこの空気袋に空気を出し入れすることによりシートクッションの長さを調整する技術が開示されている。このとき、空気袋に空気を出し入れしてシートクッション長を変化させてもシートカバーがたるむことなく常に張りを持たせておくために、シートカバー端部とフレームとの間にシートカバーをシートの内側方向に付勢するゴム材等の伸縮部材が設けられている。   Conventionally, a seat is known in which the length of a seat cushion can be adjusted according to the physique and preference of a seated person. The following Patent Document 1 discloses a technique for adjusting the length of a seat cushion by disposing an air bag between a pad with a seat cover at the front portion of the seat cushion and a frame and taking air into and out of the air bag. Yes. At this time, even if the seat cushion length is changed by taking air into and out of the air bag, the seat cover is always stretched without sagging so that the seat cover is placed between the end of the seat cover and the frame. An elastic member such as a rubber material that is urged inward is provided.

特開２００８−１４２１２０号公報JP 2008-142120 A

特許文献１に記載された従来技術では、シートカバー端部とフレームとの間にシートカバーをシートの内側方向に付勢する伸縮部材が設けられており常にシートカバー端部がフレーム方向に引っ張られている状態にある。ここで、空気袋の膨張がさほど大きくなくクッション長の伸張程度が少ない場合にはこの伸縮部材の伸張範囲内にあって問題は無い。しかし、空気袋を大きくしたり空気袋の個数を増すなどして空気袋の膨張体積を増やしてクッション長の伸張量を大きくしようとすると伸縮部材の伸縮度が大きい材料を使う必要が生じる。かかる材料の選択には自由度が大きく制限され、高価な材料の使用や複雑な構造の採用が必要となった。   In the prior art described in Patent Document 1, an elastic member that urges the seat cover toward the inner side of the seat is provided between the end of the seat cover and the frame, and the end of the seat cover is always pulled in the frame direction. Is in a state. Here, when the inflation of the air bag is not so large and the cushion length is not extended, the expansion member is within the extension range and there is no problem. However, if it is intended to increase the expansion amount of the cushion length by increasing the expansion volume of the air bag by increasing the size of the air bag or increasing the number of air bags, it is necessary to use a material having a large expansion / contraction degree of the expansion / contraction member. The choice of such materials is greatly limited in freedom and requires the use of expensive materials and the use of complex structures.

本発明は、このような点に鑑みて創案されたものである。シートクッションの長さを大きく変化させることができる乗物用シートにおいて、シートカバーが常にたるまないように張力を加えて支持し、シートクッション長を変化させてもシートカバーに皺等の外観を悪化させる現象が生じにくい乗物用シートを提供することを課題とする。   The present invention has been devised in view of these points. In a vehicle seat that can greatly change the length of the seat cushion, it is supported by applying tension so that the seat cover does not sag at all times, and even if the seat cushion length is changed, the appearance of the seat cover is deteriorated. It is an object of the present invention to provide a vehicle seat that is unlikely to cause a phenomenon.

本発明の第１発明は、シートカバーとシートフレーム間に配設された第１の空気袋に空気を出し入れすることで前記シートカバーの一部を前記シートフレームに対して変位させることができる乗物用シートであって、前記シートカバーの端部と前記シートフレームとが、第２の空気袋を介して結合されており、該第２の空気袋への空気の出し入れにより、前記シートカバーの端部と前記シートフレームとの距離を変更できることを特徴とする。   According to a first aspect of the present invention, there is provided a vehicle capable of displacing a part of the seat cover with respect to the seat frame by putting air into and out of the first air bag disposed between the seat cover and the seat frame. An end portion of the seat cover and the seat frame are coupled via a second air bag, and the end of the seat cover is removed by taking air into and out of the second air bag. The distance between the seat portion and the seat frame can be changed.

第１発明によれば、第１の空気袋に空気を出し入れすることでシートカバーの一部をシートフレームに対して変位させたとき、シートカバーの端部とシートフレームの間が空気出し入れ可能な第２の空気袋を介して結合されているので第２の空気袋中の空気圧を調整することによりシートカバーの端部をシートフレームに引き付ける量を制御することが可能である。これによって第１の空気袋に出し入れする空気量を増減してシートクッション長を大きく変化させてもシートカバーに常に一定の張力を発生させ皺等の外観不具合が生じにくくすることが可能となる。   According to the first invention, when a part of the seat cover is displaced with respect to the seat frame by taking air into and out of the first air bag, the space between the end of the seat cover and the seat frame can be taken in and out. Since it is connected via the second air bag, it is possible to control the amount by which the end of the seat cover is attracted to the seat frame by adjusting the air pressure in the second air bag. As a result, even if the amount of air to be taken in and out of the first air bag is increased or decreased to greatly change the seat cushion length, it is possible to always generate a constant tension on the seat cover and to prevent appearance defects such as wrinkles.

本発明の第２発明は、上記第１発明に係る乗物用シートであって、前記第２の空気袋に空気を導入することにより前記シートカバーの端部と前記シートフレームとの距離を短くでき、前記第２の空気袋から空気を排出することにより前記シートカバーの端部と前記シートフレームとの距離を長くできるよう構成されたことを特徴とする。   A second invention of the present invention is the vehicle seat according to the first invention, wherein the distance between the end of the seat cover and the seat frame can be shortened by introducing air into the second air bag. Further, it is characterized in that the distance between the end portion of the seat cover and the seat frame can be increased by discharging air from the second air bag.

第２発明によれば、第２の空気袋中の空気圧を高めると第２の空気袋の断面は円形状に近づきより大きくシートカバーの端部をシートフレームに対して引き付けるようになり、反対に空気圧を低くすると空気袋の断面は線状に近づいてシートカバーの端部をシートフレームに引き付ける量は小さくなる。これによって、第２の空気袋に空気を導入することによってシートカバーをシートフレームに対して引き付けることができ、より確実に常に一定の張力を発生させて皺等の外観不具合が生じにくくすることが可能となる。   According to the second invention, when the air pressure in the second air bag is increased, the cross section of the second air bag approaches a circular shape, and the end of the seat cover is attracted to the seat frame. When the air pressure is lowered, the cross section of the air bag approaches a linear shape, and the amount of the end of the seat cover attracted to the seat frame decreases. As a result, by introducing air into the second air bag, the seat cover can be attracted to the seat frame, and a constant tension can be generated more reliably and less likely to cause appearance defects such as wrinkles. It becomes possible.

本発明の第３発明は、上記第１発明又は第２発明において、前記第１の空気袋への空気の導入と前記第２の空気袋への空気の導入を同一の給排気装置により行えるよう構成されたことを特徴とする。 According to a third aspect of the present invention, in the first or second aspect of the present invention, introduction of air into the first air bag and introduction of air into the second air bag can be performed by the same air supply / exhaust device. It is structured.

第３発明によれば、第１の空気袋への空気の導入と第２の空気袋への空気の導入を１つの給排気装置で行うことができるので、簡潔な機構で前記第１発明又は第２発明の作用効果を達成することができる。 According to the third invention, since the introduction of air into the first air bag and the introduction of air into the second air bag can be performed by one air supply / exhaust device, the first invention or The effect of the second invention can be achieved.

A front panel 14 disposed in the front portion is provided and configured in a frame shape. The front panel 14 includes a flat portion 14a disposed horizontally at the front portion between the side frames 12, and an inclined portion 14b extending in an inclined manner from the front end of the flat portion 14a toward the front lower side, It is formed from a bent portion 14c provided at the front end portion of the inclined portion 14b.

シートカバー２１は、ファブリックや皮革等の表皮に薄肉のウレタン製スラブパッドであるカバーパッドと、薄手のトリコットニットや綿布製の裏基布をこの順序でラミネート固定したもので通常の乗物用シートに使用されるものである。なお、カバーパッドや裏基布をラミネートせず表皮単体とするものであってもよい。   The seat cover 21 is formed by laminating a cover pad, which is a thin-walled urethane slab pad, and a thin tricot knit or cotton base fabric in this order on an outer skin such as fabric or leather. It is what is used. It should be noted that the cover pad or the back base fabric may not be laminated and may be a single skin.

フロントパネル１４上には、空気が導入されることで膨張し、排出されることで収縮する熱可塑性ウレタン樹脂性の第１の空気袋３０が配設されている。第１の空気袋３０は、上側に位置する上部空気袋３１と、この上部空気袋３１の下側に位置する下部空気袋３５とを備えている。上部空気袋３１と下部空気袋３５は、その各基部３１ａ、３５ａにおいて、フロントパネル１４の平坦部１４ａの上面に積層されて接着により固定されている。また、上部空気袋３１と下部空気袋３５は、フロントパネル１４の傾斜部１４ｂの上面に沿って配設されている。   On the front panel 14, a first urethane bag 30 of thermoplastic urethane resin that is inflated when air is introduced and contracted when discharged is disposed. The first air bag 30 includes an upper air bag 31 located on the upper side and a lower air bag 35 located on the lower side of the upper air bag 31. The upper air bag 31 and the lower air bag 35 are laminated on the upper surface of the flat portion 14a of the front panel 14 and fixed by bonding at their base portions 31a and 35a. Further, the upper air bag 31 and the lower air bag 35 are disposed along the upper surface of the inclined portion 14 b of the front panel 14.

図２に示すように、上部空気袋３１には、左右方向に延びる前側空気袋３２と、左右方向に延びる後側空気袋３３とが一部連通して形成されている。下部空気袋３５には、左右方向に延びる一つの空気袋３６が形成されている。また、上部空気袋３１の前側空気袋３２及び後側空気袋３３と、下部空気袋３５の空気袋３６とは、第１の切換弁（不図示）を介して空気の供給源としてのコンプレッサ５０に接続されている。第１の切換弁は、給気状態と排気状態と閉止状態の３つに切り換え可能な弁で手動操作ができる。給気状態に切り換えるとコンプレッサ５０を作動させるとともに、コンプレッサ５０と上部空気袋３１の前側空気袋３２及び後側空気袋３３と、下部空気袋３５の空気袋３６とを連通させ給気可能とする。排気状態に切り換えるとコンプレッサ５０の作動を停止させるとともに、上部空気袋３１の前側空気袋３２及び後側空気袋３３と、下部空気袋３５の空気袋３６とを外気に連通させ排気可能とする。また、閉止状態とするとコンプレッサ５０の作動を停止させるとともに、上部空気袋３１の前側空気袋３２及び後側空気袋３３と、下部空気袋３５の空気袋３６への空気の出入りを止める。これによって、切換弁の操作により上部空気袋３１の前側空気袋３２及び後側空気袋３３と、下部空気袋３５の空気袋３６への給排気および流出入の閉止が行われる。このコンプレッサ５０が特許請求の範囲記載の「給気装置」に相当する。   As shown in FIG. 2, the upper air bag 31 is formed with a front air bag 32 extending in the left-right direction and a rear air bag 33 extending in the left-right direction in part. The lower air bag 35 is formed with one air bag 36 extending in the left-right direction. Further, the front air bag 32 and the rear air bag 33 of the upper air bag 31 and the air bag 36 of the lower air bag 35 are a compressor 50 serving as an air supply source via a first switching valve (not shown). It is connected to the. The first switching valve can be manually operated with a valve that can be switched between an air supply state, an exhaust state, and a closed state. When switched to the air supply state, the compressor 50 is operated, and the compressor 50, the front air bag 32 and the rear air bag 33 of the upper air bag 31, and the air bag 36 of the lower air bag 35 are communicated to enable air supply. . When switched to the exhaust state, the operation of the compressor 50 is stopped, and the front air bag 32 and the rear air bag 33 of the upper air bag 31 and the air bag 36 of the lower air bag 35 are communicated with the outside air so that the air can be exhausted. Moreover, when it is in the closed state, the operation of the compressor 50 is stopped, and the entrance and exit of air into the front air bag 32 and the rear air bag 33 of the upper air bag 31 and the air bag 36 of the lower air bag 35 are stopped. Thus, the supply / exhaust to the air bag 36 of the upper air bag 31 and the rear air bag 33 and the air bag 36 of the lower air bag 35 and the inflow / outflow are closed by the operation of the switching valve. The compressor 50 corresponds to the “air supply device” recited in the claims.

図２及び図３に示すように、シートカバー２１の端末とフロントパネル１４の折り曲げ部１４ｃ先端部との間には熱可塑性ウレタン樹脂性の第２の空気袋４０が配設されている。第２の空気袋４０には、左右方向に延びる一つの空気袋４１が形成されている。第２の空気袋４０の前側の基部４０ａはシートカバー２１の端末に対して縫製により固定され、第２の空気袋４０の後側の基部４０ｂはフロントパネル１４の折り曲げ部１４ｃ先端部に対して接着により固定されている。また、空気袋４１は、第２の切換弁（不図示）を介して空気の供給源としてのコンプレッサ５０に接続されている。このコンプレッサ５０は、第１の空気袋３０への空気の供給源としてのコンプレッサ５０と同一のものであり、共用されるものである。第２の切換弁は、給気状態と排気状態と閉止状態の３つに切り換え可能な弁で手動操作ができる。給気状態に切り換えるとコンプレッサ５０を作動させるとともに、コンプレッサ５０と空気袋４１とを連通させ給気可能とする。排気状態に切り換えるとコンプレッサ５０の作動を停止させるとともに、空気袋４１を外気に連通させ排気可能とする。また、閉止状態とするとコンプレッサ５０の作動を停止させるとともに、空気袋４１への空気の出入りを止める。これによって、切換弁の操作により空気袋４１への給排気および流出入の閉止が行われる。   As shown in FIGS. 2 and 3, a thermoplastic urethane resin second air bag 40 is disposed between the end of the seat cover 21 and the front end of the bent portion 14 c of the front panel 14. The second air bag 40 is formed with one air bag 41 extending in the left-right direction. The base 40a on the front side of the second air bag 40 is fixed to the end of the seat cover 21 by sewing, and the base 40b on the rear side of the second air bag 40 is fixed to the front end of the bent portion 14c of the front panel 14. It is fixed by bonding. The air bladder 41 is connected to a compressor 50 as an air supply source via a second switching valve (not shown). The compressor 50 is the same as the compressor 50 as a supply source of air to the first air bag 30 and is shared. The second switching valve can be manually operated with a valve that can be switched between an air supply state, an exhaust state, and a closed state. When switched to the air supply state, the compressor 50 is operated, and the compressor 50 and the air bag 41 are communicated to enable air supply. When switched to the exhaust state, the operation of the compressor 50 is stopped, and the air bag 41 is communicated with the outside air to enable exhaust. Further, when in the closed state, the operation of the compressor 50 is stopped, and the entry and exit of air into the air bag 41 is stopped. As a result, the air supply / exhaust to the air bladder 41 and the inflow / outflow are closed by operating the switching valve.

図３に示すように、第１の空気袋３０の前側空気袋３２、後側空気袋３３及び空気袋３６とに空気が供給されて、上部空気袋３１と下部空気袋３５が膨張された状態において、第２の空気袋４０は排気され断面が直線状になるように設定されている。このとき、シートカバー２１の端末とフロントパネル１４の折り曲げ部１４ｃ先端部との距離は最大となる。また、図２に示すように、第１の空気袋３０の前側空気袋３２、後側空気袋３３及び空気袋３６から空気を排出して収縮された状態において、第２の空気袋４０は給気され断面が略円形状になるように設定されている。このとき、シートカバー２１の端末とフロントパネル１４の折り曲げ部１４ｃ先端部との距離は最小となる。   As shown in FIG. 3, the air is supplied to the front air bag 32, the rear air bag 33, and the air bag 36 of the first air bag 30, and the upper air bag 31 and the lower air bag 35 are inflated. The second air bag 40 is set to be evacuated and to have a straight cross section. At this time, the distance between the terminal of the seat cover 21 and the front end of the bent portion 14c of the front panel 14 is maximized. In addition, as shown in FIG. 2, the second air bag 40 is supplied in a state in which air is discharged from the front air bag 32, the rear air bag 33, and the air bag 36 of the first air bag 30 and is contracted. It is set so that the cross section is substantially circular. At this time, the distance between the terminal of the seat cover 21 and the front end of the bent portion 14c of the front panel 14 is minimized.

以上のように構成される実施形態は、以下のような作用効果を奏する。シートクッション１０のクッション長を増大させる場合、第１の切換弁を給気状態に切り換えると、コンプレッサ５０が作動して第１の空気袋３０の前側空気袋３２、後側空気袋３３及び空気袋３６に空気が供給されてそれらが膨張する。これによって、フロントパネル１４に対してシートカバー２１前部とクッションパッド２０前部が前方に向かって押出されることによって、クッション長が増大する。この過程において、第２の切換弁は排気状態に切り換えられている。これによって、第２の空気袋４０の空気袋４１からは空気が排出され断面が直線状に近づいていく。所望のクッション長になったとき第１の切換弁を閉止状態に切り換える。このとき、シートカバー２１には所定の張力が発生しておらず皺等が発生しやすい状態にある。次に、第２の切換弁を給気状態に切り換えるとコンプレッサ５０が作動して第２の空気袋４０の空気袋４１に空気が供給されてそれが膨張する。これによって、第２の空気袋４０の空気袋４１の断面が円形に近づいていき、シートカバー２１の端末はフロントパネル１４の折り曲げ部１４ｃ先端部に向かって引っ張られていく。シートカバー２１に所定の張力が発生した状態で第２の切換弁を閉止状態に切り換える。この操作によって、シートカバー２１に皺等の外観不具合が生じにくい状態でクッション長の変更が可能となる。   The embodiment configured as described above has the following operational effects. When the cushion length of the seat cushion 10 is increased, when the first switching valve is switched to the air supply state, the compressor 50 is activated and the front air bag 32, the rear air bag 33, and the air bag of the first air bag 30 are operated. Air is supplied to 36 and they expand. Accordingly, the front portion of the seat cover 21 and the front portion of the cushion pad 20 are pushed forward with respect to the front panel 14, thereby increasing the cushion length. In this process, the second switching valve is switched to the exhaust state. As a result, air is discharged from the air bladder 41 of the second air bladder 40 and the cross section approaches a straight line. When the desired cushion length is reached, the first switching valve is switched to the closed state. At this time, a predetermined tension is not generated in the seat cover 21, and wrinkles or the like are likely to occur. Next, when the second switching valve is switched to the air supply state, the compressor 50 is operated and air is supplied to the air bag 41 of the second air bag 40 to expand it. As a result, the cross section of the air bladder 41 of the second air bladder 40 approaches a circular shape, and the end of the seat cover 21 is pulled toward the front end of the bent portion 14c of the front panel 14. The second switching valve is switched to the closed state when a predetermined tension is generated in the seat cover 21. By this operation, the cushion length can be changed in a state where appearance defects such as wrinkles are unlikely to occur in the seat cover 21.

前述のクッション長を増大させる操作において、第１の空気袋３０の前側空気袋３２、後側空気袋３３及び空気袋３６への空気の供給を続けていくと、第２の空気袋４０が最終的には直線状になる。このとき、シートカバー２１の端末とフロントパネル１４の折り曲げ部１４ｃ先端部間の距離は最長となり、クッション長は最大になる。これが図３に示す状態である。この状態では第２の切換弁は閉止状態でも排気状態でもいずれでもかまわない。   In the operation of increasing the above-described cushion length, if the supply of air to the front air bag 32, the rear air bag 33, and the air bag 36 of the first air bag 30 is continued, the second air bag 40 is finally finished. It becomes linear. At this time, the distance between the terminal of the seat cover 21 and the front end of the bent portion 14c of the front panel 14 is the longest, and the cushion length is the maximum. This is the state shown in FIG. In this state, the second switching valve may be closed or exhausted.

シートクッション１０のクッション長を減少させる場合、第１の切換弁を排気状態に切り換えると、コンプレッサ５０は作動せず、第１の空気袋３０の前側空気袋３２、後側空気袋３３及び空気袋３６の中の空気が排出されてそれらが収縮する。これによって、フロントパネル１４に対してシートカバー２１前部とクッションパッド２０前部を前方に向かって押出す力が減少することによって、クッション長が減少する。この過程において、第２の切換弁は給気状態に切り換えられている。これによって、第２の空気袋４０の空気袋４１には空気が供給され断面が円形に近づいていく。所望のクッション長になったとき第１の切換弁および第２の切換弁を同時に閉止状態に切り換える。このとき、シートカバー２１には所定の張力が発生しており皺等が皺等の外観不具合が生じにくい状態にある。かかる操作は、第１の切換弁および第２の切換弁を同時に操作する必要があり煩雑である。これを避けるためには、一旦、第１の空気袋３０の前側空気袋３２、後側空気袋３３及び空気袋３６の中の空気を排出してクッション長を減少した状態にしてから前述のクッション長を増大させる操作を行えばよい。   When reducing the cushion length of the seat cushion 10, when the first switching valve is switched to the exhaust state, the compressor 50 does not operate, and the front air bag 32, the rear air bag 33, and the air bag of the first air bag 30. The air in 36 is exhausted and they contract. As a result, the force for pushing the front part of the seat cover 21 and the front part of the cushion pad 20 toward the front with respect to the front panel 14 is reduced, so that the cushion length is reduced. In this process, the second switching valve is switched to the supply state. As a result, air is supplied to the air bladder 41 of the second air bladder 40 and the cross section approaches a circular shape. When the desired cushion length is reached, the first switching valve and the second switching valve are simultaneously switched to the closed state. At this time, a predetermined tension is generated in the seat cover 21, and the heel or the like is in a state in which appearance defects such as the heel are less likely to occur. Such an operation is complicated because it is necessary to operate the first switching valve and the second switching valve simultaneously. In order to avoid this, once the air in the front air bag 32, the rear air bag 33, and the air bag 36 of the first air bag 30 is discharged to reduce the cushion length, the above-mentioned cushion is used. An operation for increasing the length may be performed.

前述のクッション長を減少させる操作において、第１の空気袋３０の前側空気袋３２、後側空気袋３３及び空気袋３６からの空気の排出と、第２の空気袋４０への空気の供給を続けていくと、最終的には第２の空気袋４０の断面が略円形状になる。このとき、シートカバー２１の端末とフロントパネル１４の折り曲げ部１４ｃ先端部間の距離は最短となり、クッション長は最小になる。これが図２に示す状態である。この状態では第１の切換弁、第２の切換弁とも閉止状態である必要がある。   In the operation of reducing the cushion length, the air is discharged from the front air bag 32, the rear air bag 33, and the air bag 36 of the first air bag 30, and the air is supplied to the second air bag 40. If it continues, the cross section of the 2nd air bag 40 will become a substantially circular shape finally. At this time, the distance between the terminal of the seat cover 21 and the front end of the bent portion 14c of the front panel 14 is the shortest, and the cushion length is the minimum. This is the state shown in FIG. In this state, both the first switching valve and the second switching valve need to be closed.

以上、特定の実施形態について説明したが、本発明は、それらの構成に限定されず、本発明の要旨を変更しない範囲で種々の変更、追加、削除が可能である。例えば、
１．上記実施形態においては、第１の空気袋３０が、前側空気袋３２、後側空気袋３３及び空気袋３６の３つに分かれている形態としたが、これに限らず１つであっても他の複数であってもよい。
２．上記実施形態においては、第１の空気袋３０及び第２の空気袋４０への空気の出入を制御する第１の切換弁及び第２の切換弁の操作を手動で行ったが、これに限らずシートカバー２１に生じる張力を一定に制御すべく自動で行ってもよい。
３．上記実施形態においては、シートカバー２１の端部を第２の空気袋４０を介して直接フロントパネル１４に結合したが、これに限らず第２の空気袋４０とフロントパネル１４との間に布帛や樹脂シートもしくはシートカバー２１と同材質、構成の部材等を介して結合してもよい。 As mentioned above, although specific embodiment was described, this invention is not limited to those structures, A various change, addition, and deletion are possible in the range which does not change the summary of this invention.
