The invention relates to a backrest gradient supporting hardness foam structure of an integrated laminar flow ventilation duct. A universal wind collecting and rectifying structure is arranged on the foam B surface; the backrest foam is divided into three hardness areas, namely a first hardness area, a second hardness area and a third hardness area; foam reinforcing ribs with gradually-changed widths are reserved on the foam surface B from the waist to the shoulders, so that gradually-softened hardness support required by the back of the human body from the waist to the shoulders is provided; when the local thickness of the foam is larger than 50 mm, the laminar flow ventilation air channel of the first air collection and rectification structure is provided with an air outlet position structure; when the local thickness of the foam is smaller than 50 mm, the laminar flow ventilation air channel of the second air collection and rectification structure is provided with an air outlet position structure; when the local thickness of the foam is not uniform, the laminar flow ventilation air ducts of the first and second air collection rectification structures are arranged in a mixed manner at the air outlet positions; the air collecting and rectifying structure and the backrest gradually-changing supporting hardness foam structure are arranged and designed in a combined mode, so that a driver and passengers can better perceive the comfort of the ventilation environment.
本发明涉及一种集成层流通风风道的靠背渐变支撑硬度泡沫结构;在泡沫B面设置通用集风整流结构;靠背泡沫分三个硬度区,分别第一硬度区、第二硬度区、第三硬度区;泡沫B面从腰部到肩部留有渐变宽度的泡沫加强筋,提供人体背部从腰部到肩部所需的逐渐变软的硬度支撑;泡沫局部厚度大于50mm时,设置第一种集风整流结构的层流通风风道有出风口位置的结构;泡沫局部厚度小于50mm时,设置第二种集风整流结构的层流通风风道有出风口位置的结构;泡沫局部厚度不均匀时,将第一、二种集风整流结构的层流通风风道有出风口位置的结构混合设置;本发明设有集风整流结构及靠背渐变支撑硬度泡沫结构,二者结合设计,使驾乘者更能感知到通风环境舒适性。
