PROBLEM TO BE SOLVED: To provide a blowing device of a vehicular seat which comprises, across a blower, a first air blowing path at one side and a second air blowing path at the other side in a flowing direction of air of the blower, where both air blowing paths are provided along a seated surface, which is improved in the problem that sitting comfort of the seat is deteriorated, by enhancing strength of layers forming the first and second air blowing paths without impairing cushion performance and by suppressing lack in strength of the layers forming the first and second air blowing paths even if the first and second air blowing paths have great volumes.SOLUTION: In a seat cushion, a layer forming a first air blowing path 211a and second air blowing paths 42a and 211c is divided into two layers along a seated surface, and a cushion panel 42 in the layer near a counter-seated surface side is configured to have higher strength than a cushion pad 211 in the layer near the seated surface. The first and second air blowing paths are formed so that opposite sides of the respective layers are opened, and flowing between the first and second air blowing paths is shut off at an area where the first and second air blowing paths formed on the layers overlap with each other across the layers.SELECTED DRAWING: Figure 2
【課題】送風機を挟んで、送風機の空気の流れで一方側の第1送風路と、他方側の第2送風路とを備え、両送風路が着座表面に沿って設けられている乗物用シートの送風装置において、クッション性を犠牲にすることなく、第1及び第2送風路を形成する層の強度を高め、第1及び第2送風路の容積が多くても、第1及び第2送風路を形成する層の強度不足を抑制して、シートの座り心地が悪化する問題を改善する。【解決手段】シートクッションにおいて第1送風路211a及び第2送風路42a、211cを形成する層を着座表面に沿って2層に分割し、着座面側層のクッションパッド211に比べて反着座面側層のクッションパネル42は高強度に構成し、第1及び第2送風路は、各層の対向側が開放して形成され、各層に形成された第1及び第2送風路が層を跨って重なる領域では、第1及び第2送風路間の空気の通流が遮断されている。【選択図】図2
