The invention relates to the field of automobile seats, in particular to a seat backrest foaming air duct structure which is characterized in that a foaming seat backrest is formed in a foaming mode, a groove is formed in the foaming seat backrest, through holes are formed in the inner wall of the groove, the diameter of the through holes ranges from 15 mm to 30 mm, and the distribution density of the through holes in the vertical direction of the foaming seat backrest is gradually increased. A sealing assembly can cover a U-shaped groove, a ventilation hole is formed in the sealing assembly, the ventilation hole can communicate with an air pipe output port of a fan, and the fan can circulate internal air to the outside; the ventilation volume is reduced, the fan power is fixed, the single-volume ventilation quantity is increased, the ventilation effect is enhanced, and the heat dissipation effect is improved.

    本发明申请涉及汽车座椅领域,尤其涉及一种座椅靠背发泡风道结构,其特征在于,发泡座椅靠背发泡成型,在发泡座椅靠背上开槽,槽的内壁开设通孔,通孔的直径大小范围在15mm‑30mm之间,通孔沿发泡座椅靠背竖向方向上分布密度逐渐变大,封闭组件能够覆盖U形槽,且封闭组件上设置有通风孔,通风孔能够连通风机的风管输出口,风机能够将内部的空气流通于外;通风体积减小,风机功率一定,单体积通风量增大,通风效果增强,散热效果提高。
