た。FIG. 6 is a perspective view showing a state in which such a seat heater is mounted on a seat of an automobile. In the seat heater 4, a central portion 5 is a seat center B of a seat A, and a side portion 6 is a seat side C. Is attached to. A seat heater is also attached to the back portion D of the seat A. The heater wiring direction of the central portion 5 of the seat heater 4 is shown in FIG.
As shown in (b), most of the lateral direction is with respect to the seat, and with respect to the side portion 6, as shown in (3), the straight line portion is a mixture of the lateral direction and the longitudinal direction with respect to the seat.

の前後方向に構成されている。As shown in FIG. 1, in the seat heater 9 of this embodiment, the heater wire 1 is sewn and fixed to the support 2 by the upper thread and the lower thread by an automatic sewing machine as in the case of FIG. The wiring direction of the heater wire 1 of the side portion 6 is configured in the front-back direction of the seat.
【００１７】以上のように構成することにより、シート
への乗降時の荷重でシートサイドＣが押しつぶされてサ
イド部６にシワが発生してももヒータ線１は、荷重方向

で、対策後の数値は十分に満足できるものといえる。[0020] Generally, the entry / exit endurance standard of an automobile manufacturer is not definite but is said to be 25,000 times or more, so it can be said that the value after the countermeasure is sufficiently satisfactory.
【００２１】（実施例２）図２は、本発明の第２の実施
例２におけるシートヒータの平面図である。(Embodiment 2) FIG. 2 is a plan view of a seat heater according to a second embodiment 2 of the present invention.
【００２２】実施例１と異なるところは中央部５とサイ
ド部６の連結部１１がシートの前方に位置し、サイド部
６のヒータ配線の折返し点Ｆがシート全体の前後距離Ｈ
の、後方より１／３以内に配置されていることである。The difference from the first embodiment is that the connecting portion 11 between the central portion 5 and the side portion 6 is located in front of the seat, and the turning point F of the heater wiring of the side portion 6 is the front-rear distance H of the entire seat.
It is arranged within 1/3 of the rear.
【００２３】このように構成することにより、乗降時最
も荷重のかかり易いサイド部６の中心付近から、折返し
点を遠ざけることができるのでヒータ線１にかかる荷重
を軽減できる。With this configuration, the turning point can be moved away from the vicinity of the center of the side portion 6 where the load is most likely to be applied when getting on and off, so that the load applied to the heater wire 1 can be reduced.
【００２４】本実施例ではヒータ線１を支持体２に固定
するための方法として、ミシンによる自動配線を用いた
が、図３に示すようにヒータ線１を支持体２ａ、２ｂで
貼り合わせて固定するという方法でも同様の効果がある
ことはいうまでもない。In the present embodiment, automatic wiring by a sewing machine was used as a method for fixing the heater wire 1 to the support body 2. However, as shown in FIG. 3, the heater wire 1 is bonded to the support bodies 2a and 2b. Needless to say, the method of fixing has the same effect.
【００２５】尚、サイド部６の配線方向をシートの前後

り、問題はない。There is a concern that the length of the heater wire 1 will be shorter than in the conventional case and the warmth of the side portion will be reduced by making the wiring direction of the side portion 6 forward and backward of the seat. The original purpose of arranging the side portions is to obtain warmth of a fluffy atmosphere from the left and right sides of the seat when seated, and there is no problem.
【００２６】さらに、図４に示すように、連結部１１を

あれば必ずしも必要ではない。Further, as shown in FIG. 4, by providing the connecting portions 11 on both the seat rear side and the seat front side, the movement of the side portions can be restricted, and the workability when sewing to the seat is improved. Can be improved. In addition, although 12 is a through hole of the fishing cloth of the seat surface, it is not always necessary if it is not necessary for the structure of the seat.

ため、乗降時の荷重ストレスに強く断線のない信頼性の
高いシートヒータが得られる。As described above, according to the present invention, since the wiring direction of the heater wire on the side portion is in the front-back direction of the seat, the seat heater is highly resistant to load stress at the time of getting on and off and has high reliability and is not broken. Is obtained.
