The invention provides a ventilation type seat backrest supporting back plate which is characterized in that a side sealing wall is arranged at the edge of the back plate, so that the side sealing wall and a wind bag film are mutually sealed; a ventilation space is formed in the air bag film and the back plate. A first ventilation opening is formed in the back plate, and a plurality of first ventilation holes are formed in the air bag film; and an air guide channel is formed in a ventilation space between the first ventilation opening and the first air hole. And gas passes through the first ventilation opening, the air guide channel and the first ventilation hole in sequence and continuously flows. By means of the mode, the structure of the back plate is improved, and an air guide channel is formed between the air bag film and the back plate. Compared with an existing mode, the mode that the air guide channel is arranged in the back plate has the advantages that the thickness of at least one layer of inner wall is reduced, the air bag and the back plate are combined, control over the arrangement space and the development cost is reduced, and a new integrated component is formed; the integrated and platform design is realized, and the development period and cost are greatly reduced.
本发明提供一种通风型座椅靠背支撑背板,包括:在背板的边缘处设置侧边密封墙,进而使侧边密封墙于风袋膜相互保持密封;在风袋膜和背板内部形成通风空间。背板上开设有第一通风口,风袋膜上开设有多个第一透气孔;第一通风口与第一透气孔之间的通风空间内形成导风通道。气体先后经过第一通风口、导风通道和第一透气孔,并持续流动。通过上述方式,对背板的结构进行改进,使风袋膜与背板之间形成导风通道。这种将导风通道设置在背板内部的方式与现有的方式相比至少减少了一层内壁的厚度,将风袋与背板两个零件相结合,减少布置空间及开发成本的管控,形成一种新的集成化的部件;实现了集成化,平台化的设计,大大缩减了开发周期及成本。
