以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

（実施の形態１）
本発明の第１の実施の形態を図１および図２を参照して説明する。 (Embodiment 1)
A first embodiment of the present invention will be described with reference to FIG. 1 and FIG.

図１は本発明の第１の実施の形態における暖房用の座席の外観図である。図中、座席１のシートバック２とシートクッション３には、着座した人体の後正中線に相対して発熱手段としてのシートヒータ５ａ、５ｂが配設されていて、それぞれ着座した人体の脊髄近傍と臀部中央部を加熱する。図２に人体の後正中線の外観図を示した。後正中線は人体計測で用いられる計測線の一つで、同図より脊髄Ｓや臀部Ｂの中央部を通る直線として表されている。 FIG. 1 is an external view of a heating seat in the first embodiment of the present invention. In the figure, the seat back 2 and the seat cushion 3 of the seat 1 are provided with seat heaters 5a and 5b as heat generating means relative to the rear midline of the seated human body, respectively, in the vicinity of the spinal cord of the seated human body And heat the center of the buttocks. FIG. 2 shows an external view of the back midline of the human body. The posterior median line is one of measurement lines used in human body measurement, and is represented as a straight line passing through the central part of the spinal cord S and the buttocks B from the figure.

シートヒータ５ａ、５ｂは通電により発熱する可撓性を有した面状発熱体で、例えば、電気ヒータ線を基布に蛇行配設して成形したものである。 The sheet heaters 5a and 5b are flexible sheet heating elements that generate heat when energized. For example, the sheet heaters 5a and 5b are formed by meandering electric heater wires on a base fabric.

座席１のシートバック２とシートクッション３にはそれぞれ凸部６ａ、６ｂが形成されている。凸部６ａ、６ｂはシートバック２とシートクッション３を構成する軟質ウレタンフォームを成形する際に人体着座側表面に設けられたものである。そして、シートヒータ５ａ、５ｂはそれぞれ凸部６ａ、６ｂと座席１の表皮（図示せず）との間に配設されている。 Protrusions 6 a and 6 b are formed on the seat back 2 and the seat cushion 3 of the seat 1, respectively. The convex portions 6 a and 6 b are provided on the human body seating side surface when the flexible urethane foam constituting the seat back 2 and the seat cushion 3 is molded. The seat heaters 5a and 5b are disposed between the convex portions 6a and 6b and the skin (not shown) of the seat 1, respectively.

上記構成により、人体の後正中線に相対してシートヒータ５ａ、５ｂを配設したので、寒冷下での脊髄近傍や臀部中央部からの放熱増加を抑制し、脊髄近傍や臀部中央部を暖房するので、体感的に十分な暖房を享受できるようになる。また、加熱面が脊髄近傍や臀部中央部の狭い範囲なので加熱エネルギーが少なくてよく、省エネ効果がある。 With the above configuration, since the seat heaters 5a and 5b are disposed relative to the posterior midline of the human body, an increase in heat radiation from the vicinity of the spinal cord and the center of the buttocks in the cold is suppressed, and the vicinity of the spinal cord and the center of the buttocks are heated. As a result, it becomes possible to enjoy a sufficient amount of heating. In addition, since the heating surface is a narrow area near the spinal cord or the center of the buttocks, less heating energy is required, and an energy saving effect is obtained.

また、座席１に設けられた凸部６ａ、６ｂが人体背面中央の凹部（脊髄位置）や臀部中央部の凹部と隙間無く密着するので、凸部６ａ、６ｂに配設されたシートヒータ５ａ、５ｂからの発生熱を人体へ効率的に伝えることができる。 Further, since the convex portions 6a and 6b provided on the seat 1 are in close contact with the concave portion (spinal cord position) at the center of the back of the human body and the concave portion at the central portion of the buttocks, there is no gap, so the seat heater 5a disposed on the convex portions 6a and 6b, Heat generated from 5b can be efficiently transmitted to the human body.

尚、本実施の形態では、脊髄位置に相対して縦長のシートヒータ５ａを配設したが、例えば、シートヒータを所定の企画寸法にモジュール化してもよい。図３にモジュール化したシートヒータを配設した暖房用の座席の外観図を示す。同図に示したように、シートヒータ５ａはモジュール化した２つのシートヒータ５ｃ、５ｄに分割してシートバック２に配設してある。尚、シートクッション３に配設したシートヒータ５ｂもモジュール化したシートヒータを用いればよい。モジュール化により、シートヒータの合理化が図れるとともに、座席形状に合わせてさまざまな組合せが可能となり、使い勝手が向上する。 In the present embodiment, the vertically long seat heater 5a is disposed relative to the spinal cord position. However, for example, the seat heater may be modularized to a predetermined planned size. FIG. 3 shows an external view of a heating seat provided with a modular seat heater. As shown in the figure, the seat heater 5a is divided into two modular seat heaters 5c and 5d and arranged on the seat back 2. The seat heater 5b disposed on the seat cushion 3 may be a modular seat heater. Modularization makes it possible to rationalize the seat heater and allows various combinations according to the seat shape, improving usability.

（実施の形態２）
本発明の第２の実施の形態を図４および図５を参照して説明する。 (Embodiment 2)
A second embodiment of the present invention will be described with reference to FIGS.

図４は本発明の第２の実施の形態における暖房用の座席の外観図である。第1の実施の形態では、着座した人体の後正中線に相対してシートヒータ５ａ、５ｂを配設したが、本実施の形態では、図４に示すように、着座した人体の後正中線と後大腿部とに相対してモジュール化したシートヒータ５ｂ〜５ｅを配設している。この構成により、後大腿部にも
相対してシートヒータ５ｅを配設したので、さらに暖房感が向上する。 FIG. 4 is an external view of a heating seat in the second embodiment of the present invention. In the first embodiment, the seat heaters 5a and 5b are disposed relative to the back midline of the seated human body. However, in the present embodiment, as shown in FIG. 4, the back midline of the seated human body. The seat heaters 5b to 5e that are modularized are disposed opposite to the rear thigh. With this configuration, since the seat heater 5e is also disposed relative to the rear thigh, the feeling of heating is further improved.

また、本実施の形態では、モジュール化されて分割されたシートヒータ５ｂ〜５ｅを交互に発熱制御する制御手段（図示せず）を備えている。この制御方法を図５に基づき説明する。図５はシートヒータ５ｂ〜５ｅの発熱制御シーケンスを示す動作図である。同図より、時刻ｔ０で人体が着座してシートヒータ５ｂ〜５ｅの通電をオンすると、時刻ｔ１まではシートヒータ５ｂ〜５ｅ全てを通電して暖房の立ち上がりを早める。時刻ｔ１は通電前の室温によるが、温熱的中立レベルの暖房感を得られる時間として、少なくとも５〜１０分程度の間で設定すればよい。 Moreover, in this Embodiment, the control means (not shown) which controls heat_generation | fever alternately by the sheet heaters 5b-5e divided | segmented into the module is provided. This control method will be described with reference to FIG. FIG. 5 is an operation diagram showing a heat generation control sequence of the seat heaters 5b to 5e. As shown in the figure, when the human body is seated at time t0 and the energization of the seat heaters 5b to 5e is turned on, all the seat heaters 5b to 5e are energized until the start of heating until time t1. Although the time t1 depends on the room temperature before energization, the time t1 may be set to at least about 5 to 10 minutes as a time for obtaining a thermal neutral level heating feeling.

次に、時刻ｔ１以降は、図５に示すように、各シートヒータ５ｂ〜５ｅを時間幅Ｔで交互にオンオフ制御する。ここで、時刻ｔ１まではシートヒータ５ｂ〜５ｅ全てが通電オンされて座席１が暖まり、人体の熱容量もあるのでシートヒータ５ｂ〜５ｅの通電をオフしても人体接触面の温度は急激に低下することは無く、ｔ１以降は各シートヒータ５ｂ〜５ｅを時間幅Ｔで交互にオンオフ制御しても暖房感が維持される。時間幅Ｔは実験的に予め求めておくことが可能である。 Next, after time t1, as shown in FIG. 5, the seat heaters 5b to 5e are alternately turned on and off with a time width T. Here, until time t1, all the seat heaters 5b to 5e are energized and the seat 1 is warmed, and there is also a heat capacity of the human body, so even if the energization of the seat heaters 5b to 5e is turned off, the temperature of the human body contact surface rapidly decreases. After t1, the heating feeling is maintained even if the seat heaters 5b to 5e are alternately turned on and off by the time width T. The time width T can be obtained experimentally in advance.

上記制御により、全シートヒータ５ｂ〜５ｅを通電する場合に比べて交互通電する場合は、シートヒータ５ｂ〜５ｄで消費電力を１／５に、シートヒータ５ｅで消費電力を２／５に低減すことが可能となり、快適性を維持しながらも省エネが実現できる。 With the above control, when the energization is alternately performed as compared with the case where all the seat heaters 5b to 5e are energized, the power consumption is reduced to 1/5 by the seat heaters 5b to 5d and the power consumption is reduced to 2/5 by the seat heater 5e. It is possible to save energy while maintaining comfort.

尚、上記構成では、時間幅Ｔを一定としたが、例えば、姿勢により密着性のばらつきが大きくなるシートヒータ５ｃについては放熱損失が大きいため他のシートヒータよりもＴを長く設定する等、シートヒータ位置での人体と座席との密着度合いに応じてＴを変える構成としてもよく、暖房感をより維持することが可能となる。 In the above configuration, the time width T is constant. However, for example, the seat heater 5c in which the variation in adhesion is large depending on the posture has a large heat dissipation loss, so that the sheet heater 5c is set longer than the other seat heaters. It is good also as a structure which changes T according to the contact | adherence degree of the human body and seat in a heater position, and it becomes possible to maintain a feeling of heating more.

以上の実施の形態では、シートヒータとして電気ヒータ線を基布に蛇行配設して成形したものを用いたが、ＰＴＣ抵抗体からなる可撓性を有した面状発熱体を用いてもよく、電気ヒータ線に比して温度むらがなく、さらに快適で省エネな暖房が可能となる。 In the above embodiment, the sheet heater is formed by meandering the electric heater wire on the base fabric, but a flexible sheet heating element made of a PTC resistor may be used. Compared to electric heater wires, there is no temperature unevenness, and more comfortable and energy-saving heating is possible.

以上のように、本発明にかかる暖房装置は、自動車や一般住宅、オフィス、航空機、劇場、屋外観戦場所、屋外作業場所等のさまざまな座席での多様な暖房に展開が可能である。 As described above, the heating device according to the present invention can be applied to various heating in various seats such as automobiles, ordinary houses, offices, airplanes, theaters, outdoor watching places, outdoor work places, and the like.
