PROBLEM TO BE SOLVED: To solve the problems that: a seating face and a back pad face of a seat is generally not well ventilated, readily causing sweating and unpleasantness, nevertheless, producing a specially-designed cushion in order to solve the unpleasantness becomes costly; and also, heating wires used for warming cannot follow stretching/contracting of the cushion, and therefore, causing the wires to be broken by fatigue.SOLUTION: Three-dimensional fiber for securing a ventilation passage is inserted between a bottom surface side formed of air impermeable fiber and an upper surface having air permeability of a bag shape, and cool air and warm air are sent therein from an air blower through a duct with an air-flow adjustment valve and are blown out from the upper surface having air permeability. The invention thus becomes free from the conventional dedicated design and can be integrated with a seat or can be applied as an upper surface cover of the seat, to enable expansion of the scope of product design because of versatility thereof and also cost reduction. Further, a risk such as damaging of heating wires can be eliminated, thereby a highly durable cool/warm air blowing system can be provided.SELECTED DRAWING: Figure 1
【課題】シートの座面および背当て面は一般的に通気が悪く汗ばんだりして不快感が出易かった。それを解決する為には専用設計したクッション成形を必要とする為にコストが高い。また暖房では電熱線を使う事でクッションの伸縮に追従出来ずに疲労断線する事が有った。【解決手段】無通気性の繊維を使った底面側と通気性を持った上面の袋状の間に通気路を確保する立体型繊維を入れて、風量調整バルブ付きダクトを介して送風機より冷気及び暖気を送り込み通気性を持った上面から吹き出して使用することで、従来の専用設計に捉われず、一体化またはシートの上面カバーとして設定でき汎用性がある為に商品の設計範囲を広げるとともにコストダウンが可能に成る。また、電熱線の様な故障リスクを排除出来るため耐久性の高いシートの冷・暖送風システムを提供できる。【選択図】図1
