Description

本発明は、自動車用冷暖房通風シートの熱電素子装着構造に係り、より詳細には、ランバーサポート装置と熱電素子方式の冷暖房通風シートが同時に適用されたシートにおいて、ランバーサポート装置の作動時、シートバック形状が不連続となって発生する座り心地感の悪さを解消し、ランバーサポートによってシートバックパッドが前後に動いても、熱電素子の空気吐出口とシートバックパッドとの間の機密が維持され、空気漏出による冷暖房効率の低下を防止した自動車用冷暖房通風シートの熱電素子装着構造に関する。   The present invention relates to a thermoelectric element mounting structure for an air conditioning / ventilation sheet for automobiles, and more specifically, in a seat to which a lumbar support device and a thermoelectric element type air conditioning / ventilation sheet are applied simultaneously, Even if the seat back pad moves back and forth by the lumbar support, the confidentiality between the air outlet of the thermoelectric element and the seat back pad is maintained, eliminating the inconvenience of sitting comfort caused by the discontinuity of the shape, The present invention relates to a thermoelectric element mounting structure for an automotive cooling / heating ventilation sheet that prevents a decrease in cooling / heating efficiency due to air leakage.

一般に、自動車のシートは、車内の限定された空間に、許容される重量の範囲内で設けられ、安全かつ快適に乗客を支持する。その配置によってシートはフロントシートとリアシートに分けられ、フロントシートはさらに運転席と助手席に分けられる。   In general, an automobile seat is provided in a limited space in a vehicle within an allowable weight range, and supports a passenger safely and comfortably. Depending on the arrangement, the seat is divided into a front seat and a rear seat, and the front seat is further divided into a driver seat and a passenger seat.

フロントシートに着席する運転者は、運転習慣及び乗客の身体条件によって、シートを前側に引き寄せ、あるいは後側に動かして着席する。一方、リアシートに着席する乗客が長身の場合には、フロントシートを前側に動かしてリアシートに着席させる場合もある。   A driver who sits on the front seat draws the seat to the front side or moves the seat to the rear side depending on driving habits and passengers' physical conditions. On the other hand, if the passenger seated in the rear seat is tall, the front seat may be moved forward and seated in the rear seat.

このようなシートのうちフロントシートには、運転者の背中を支持するシートバックがある。シートバックは、内部にシートバックフレームが備えられ、上部にヘッドレストが差し込まれ、その下部に回動装置を用意して運転者にとってシートの一番楽な姿勢に調節できる。   Among such seats, the front seat includes a seat back that supports the driver's back. The seat back is provided with a seat back frame, a headrest is inserted in the upper part, and a rotating device is prepared in the lower part of the seat back so that the driver can adjust the seat to the most comfortable posture.

しかし、長時間の運転時、搭乗者の着座姿勢の変化には根本的に対応が難しく、そのため自動車のシートバック内部には、搭乗者の背中を囲む緩衝装置及び腰部（Ｌｕｍｂｅｒ）を支えて腰の負担を軽減し、楽な着座姿勢を維持するランバーサポート装置が内蔵される。   However, when driving for a long time, it is fundamentally difficult to respond to changes in the sitting posture of the occupant. For this reason, a shock absorber and a waist that surround the occupant's back are supported in the seat back of the automobile. Built-in lumbar support device that reduces the burden on the user and maintains an easy sitting posture.

韓国登録特許第２０−０１７２３５６号には、車室内の空気をシートクッション下端部に装着されたブロワーで吸入し、ダクトを介してシートの着座面へ送り、冷暖房された空気として吐出できるように、ペルテェ効果（ｐｅｌｔｉｅｒ ｅｆｆｅｃｔ）を利用した熱電素子（１０、ＴＥＤ：Ｔｈｅｒｍｏ Ｅｌｅｃｔｒｉｃ Ｄｅｖｉｃｅ）をシートバック内部に装着する構成が示されている。   In Korean Registered Patent No. 20-0172356, air in the passenger compartment is sucked by a blower attached to the lower end of the seat cushion, sent to the seating surface of the seat through the duct, and discharged as air-conditioned air. A configuration is shown in which a thermoelectric element (10, TED: Thermo Electric Device) using a Peltier effect is mounted inside a seat back.

従来は、図５、図６に示すように、シートバック３にランバーサポート装置と熱電素子方式の冷暖房通風シートが同時に適用された場合、ランバーサポート装置を作動させると、ランバープレート２１がシートバックパッド５の下端部を押し出すので、シートバックパッド５が前方に突出される。この時、熱電素子１０がシートバックパッド５にマウンティングブラケット１２′を介して直接装着されているので、熱電素子１０も一緒に移動しようとする構造である。   Conventionally, as shown in FIG. 5 and FIG. 6, when a lumbar support device and a thermoelectric element type cooling / heating ventilation sheet are applied to the seat back 3 at the same time, when the lumbar support device is operated, the lumbar plate 21 becomes the seat back pad. Since the lower end of 5 is pushed out, the seat back pad 5 protrudes forward. At this time, since the thermoelectric element 10 is directly attached to the seat back pad 5 via the mounting bracket 12 ′, the thermoelectric element 10 also moves together.

この場合、シートバックパッド５と熱電素子１０との間には、格子形状にワイヤが設置されたフレーム形態の荷重支持構造物７があり、熱電素子１０の移動を邪魔する。そのため、シートバックパッド５の下端面は前方に突出されるが、シートバックパッド５の上端面は熱電素子１０が相対的に引っ張る形になり、図６に示すように、シートバック３の着座面が不連続的な輪郭（ｃｏｎｔｏｕｒ）を形成するようになり、座り心地感が低下してしまう問題点がある。
韓国登録特許第２０−０１７２３５６号 特開２００１−２７５７８４号公報 In this case, between the seat back pad 5 and the thermoelectric element 10, there is a load supporting structure 7 in the form of a frame in which wires are installed in a lattice shape, which obstructs the movement of the thermoelectric element 10. Therefore, the lower end surface of the seat back pad 5 protrudes forward, but the upper end surface of the seat back pad 5 has a shape in which the thermoelectric element 10 is pulled relatively, and as shown in FIG. However, there is a problem in that a discontinuous contour is formed and the feeling of sitting is lowered.
Korean Registered Patent No. 20-0172356 JP 2001-275784 A

本発明は、上記のような問題点を解決するためになされたもので、その目的は、ランバーサポート装置と熱電素子方式の冷暖房通風シートとが同時に適用された車両において、ランバーサポート装置の作動時、シートバック形状の不連続によって発生する座り心地感の悪さを解消することにある。すなわち、熱電素子をシートバックの荷重支持構造物に装着してシートバックパッドが自由に動くようにする一方、ランバーサポートによってシートバックパッドが前後に動く時は、熱電素子の空気吐出口とシートバックパッドとの間の機密が維持されるように、ベローズを連結し、空気漏出による冷暖房の効率低下を防止した自動車用冷暖房通風シートの熱電素子装着構造を提供することである。   The present invention has been made to solve the above-described problems, and its object is to provide a vehicle in which a lumbar support device and a thermoelectric element air-conditioning / ventilation sheet are applied at the same time when the lumbar support device is in operation. The object is to eliminate the poor sitting comfort caused by the discontinuity of the seat back shape. That is, the thermoelectric element is attached to the load support structure of the seat back so that the seat back pad can move freely, while when the seat back pad moves back and forth by the lumbar support, the air discharge port of the thermoelectric element and the seat back To provide a thermoelectric element mounting structure for an air conditioning / ventilation sheet for an automobile, in which a bellows is connected so as to maintain confidentiality between the pad and a cooling / heating efficiency reduction due to air leakage is prevented.

好ましい実施形態として、前記ランバーサポート装置が作動する時、前記シートバックパッドが前方に突出すると、前記シートバックパッドと前記熱電素子の空気吐出口が離脱しないように、前記シートバックパッドと前記空気吐出口の間にベローズを連結したことを特徴とする。   As a preferred embodiment, when the lumbar support device is operated, if the seat back pad protrudes forward, the seat back pad and the air discharge port are prevented from separating from the air outlet of the thermoelectric element. A bellows is connected between the outlets.

本発明による自動車用の冷暖房通風シートの熱電素子装着構造によれば、ランバーサポート装置の作動時、シートバックの不連続な輪郭を解消してシートの座り心地感を向上させることができる。   According to the thermoelectric element mounting structure for an air conditioning / ventilating seat for automobiles according to the present invention, when the lumbar support device is operated, the discontinuous contour of the seat back can be eliminated and the seating feeling of the seat can be improved.

また、ランバーサポート装置によってシートバックパッドが前後に動いても、ベローズによって熱電素子の空気吐出口とシートバックパッドとの間の機密が維持されるので、空気漏出による冷暖房効率の低下を防止することができる。   In addition, even if the seat back pad moves back and forth by the lumbar support device, the bellows maintains the confidentiality between the air discharge port of the thermoelectric element and the seat back pad, thus preventing a decrease in cooling and heating efficiency due to air leakage. Can do.

以下、図面を参照しながら、本発明の実施例を詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

図１は、本発明に係る自動車用の冷暖房通風シートの熱電素子装着構造を示した図である。図２及び図３は、本発明に係る自動車用の冷暖房通風シートの熱電素子装着構造において、ランバーサポート装置の作動前と作動後の状態を示す作動図である。図４は、本発明に係る自動車用の冷暖房通風シートの熱電素子装着構造において、ランバーサポート装置の作動時、シートバックパッドの作動状態を示す図である。   FIG. 1 is a view showing a thermoelectric element mounting structure of a cooling / heating ventilation sheet for an automobile according to the present invention. 2 and 3 are operation diagrams showing states before and after the operation of the lumbar support device in the thermoelectric element mounting structure for an air conditioning / heating draft sheet for automobiles according to the present invention. FIG. 4 is a diagram showing an operating state of the seat back pad when the lumbar support device is operating in the thermoelectric element mounting structure for an air conditioning / ventilating seat for automobiles according to the present invention.

図１に示すように、自動車用シートに内蔵して搭乗者の着座面で冷暖房空気を吐出させる熱電素子１０は、特に、シートバックパッド５後方のインサート成形された部位に装着されていて、本発明の好ましい実施形態において、熱電素子１０は、シートバックパッド５の後方に位置する格子状のワイヤが設置されたフレーム形態のシートバック荷重支持構造物７にマウンティングブラケット１２を介して装着されている。   As shown in FIG. 1, a thermoelectric element 10 that is built in an automobile seat and discharges air-conditioning air on a seating surface of a passenger is particularly mounted on an insert-molded portion behind a seat back pad 5. In a preferred embodiment of the invention, the thermoelectric element 10 is mounted via a mounting bracket 12 on a seat back load support structure 7 in the form of a frame in which grid-like wires located behind the seat back pad 5 are installed. .

このように、熱電素子１０が、シートバックパッド５に装着されるのではなく、シートバックパッド５の直後に位置するシートバック荷重支持構造物７に装着される場合、搭乗者の腰を楽に支えるランバーサポート装置２０が作動した場合でも、シートバックパッド５は、上下端部全体が自由に前後方向に動くので、自然な輪郭（ｃｏｎｔｏｕｒ）を形成することができる。   Thus, when the thermoelectric element 10 is not attached to the seat back pad 5 but is attached to the seat back load support structure 7 positioned immediately after the seat back pad 5, the passenger's waist is easily supported. Even when the lumbar support device 20 is actuated, the seat back pad 5 can freely move in the front-rear direction, so that a natural contour can be formed.

これによって、シートバック３の不連続な輪郭が解消されるので、シート１の座り心地感を向上させる。   As a result, the discontinuous contour of the seat back 3 is eliminated, so that the sitting comfort of the seat 1 is improved.

しかしながら、ランバーサポート装置２０が作動する時、シートバックパッド５が自由に前方に移動すると、シートバックパッド５から熱電素子１０の空気吐出口１１が離脱して、冷暖房空気が漏出される可能性がある。これを改善するためにシートバックパッド５面と空気吐出口１１との間にベローズ３０を設けた。   However, when the lumbar support device 20 is operated, if the seat back pad 5 freely moves forward, the air discharge port 11 of the thermoelectric element 10 may be detached from the seat back pad 5 and air conditioning air may leak out. is there. In order to improve this, a bellows 30 is provided between the surface of the seat back pad 5 and the air discharge port 11.

図２及び図３に示したシートバックパッド５の移動の前と後の状態において、先ず、図２は、ランバーサポート装置２０の作動前の状態として、シートバック荷重支持構造物７に装着された熱電素子１０の空気吐出口１１が、シートバックパッド５面と近接するように位置する。空気吐出口１１及びシートバックパッド５面の間には、ベローズ３０が折られた状態に連結されている。   In the state before and after the movement of the seat back pad 5 shown in FIGS. 2 and 3, first, FIG. 2 is attached to the seat back load support structure 7 as a state before the operation of the lumbar support device 20. The air discharge port 11 of the thermoelectric element 10 is positioned so as to be close to the surface of the seat back pad 5. A bellows 30 is connected in a folded state between the air discharge port 11 and the seat back pad 5 surface.

図３は、ランバーサポート装置２０の作動後の状態として、シートバックパッド５が搭乗者の身体を囲むように前方に押し出される。そのため、熱電素子１０の空気吐出口１１がシートバックパッド５面と相対的に離れて位置する。空気吐出口１１及びシートバックパッド５面との間に、ベローズ３０が位置して、その周面が直線方向に弾力的に伸張され、空気吐出口１１とシートバックパッド５面との間の空いている長さを補償する。   FIG. 3 shows the state after the operation of the lumbar support device 20 as the seat back pad 5 is pushed forward so as to surround the body of the passenger. Therefore, the air discharge port 11 of the thermoelectric element 10 is positioned relatively away from the seat back pad 5 surface. A bellows 30 is located between the air discharge port 11 and the seat back pad 5 surface, and its peripheral surface is elastically stretched in a straight line direction, so that there is a space between the air discharge port 11 and the seat back pad 5 surface. Compensate for the length.

すなわち、上記のように、ランバーサポート装置２０と熱電素子方式の冷暖房通風シート１が同時に適用される場合、ランバーサポート装置２０の作動時にランバープレート２１がシートバックパッド５を前方に突出させると、シートバックパッド５とシートバック３内部のシートバック荷重支持構造物７に固定されている熱電素子１０の間の間隔が空くが、その間に装着されるベローズ３０が伸びるので、空気吐出口１１がシートバックパッド５から離脱することを防止する。   That is, as described above, when the lumbar support device 20 and the thermoelectric element type cooling / heating ventilation seat 1 are applied at the same time, when the lumbar plate 21 projects the seat back pad 5 forward when the lumbar support device 20 is operated, the seat The space between the back pad 5 and the thermoelectric element 10 fixed to the seat back load support structure 7 inside the seat back 3 is widened, but the bellows 30 mounted between them is extended, so that the air discharge port 11 becomes the seat back. It is prevented from detaching from the pad 5.

このように、熱電素子１０の空気吐出口１１とシートバックパッド５との間の機密が維持され、冷暖房空気の漏出による冷暖房効率の低下が防止される。   In this way, confidentiality between the air discharge port 11 of the thermoelectric element 10 and the seat back pad 5 is maintained, and a decrease in cooling / heating efficiency due to leakage of cooling / heating air is prevented.

以上、本発明は、上述の好ましい実施形態に限定されるものではなく、本発明の基本概念に基づき様々に変更が可能であり、そのような形態も本発明の技術範囲に属する。   As described above, the present invention is not limited to the above-described preferred embodiments, and various modifications can be made based on the basic concept of the present invention, and such forms also belong to the technical scope of the present invention.

本発明による自動車用シートの熱電素子装着構造は、シートにランバーサポート装置と冷暖房通風機構が同時に適用される場合に好適である。   The thermoelectric element mounting structure for an automobile seat according to the present invention is suitable when the lumbar support device and the cooling / heating ventilation mechanism are simultaneously applied to the seat.
