The invention discloses a cushion capable of achieving hardness adjustment, an automobile seat and a cushion hardness adjustment method. The cushion comprises a supporting plate, air bags are distributed on the upper side of the supporting plate, a gap is formed between every two adjacent air bags, the gaps are filled with flexible materials, and height limiting structures are arranged in the air bags; in the inflation process of the air bag, the height limiting structure is used for forcing the air bag to expand outwards in the circumferential direction so as to horizontally extrude the flexible material, the number of materials in the unit section of the flexible material is increased, the hardness of the flexible material is increased, and therefore the hardness of the cushion is increased. Conversely, in the deflation process of the air bag, the horizontal extrusion force is reduced, the material in the unit section of the flexible material is reduced, and the hardness of the flexible material is reduced, so that the softness of the cushion is increased.
本发明公开了一种可实现硬度调节的坐垫、汽车座椅和坐垫硬度调节方法,坐垫包括支撑板,支撑板的上侧分布有气袋,相邻两个所述气袋之间具有间距,该间距内填充有柔性物料,所述气袋内部设有限高结构;所述气袋充气过程中,限高结构用于迫使气袋的周向向外膨胀,以水平挤压所述柔性物料,柔性物料单位截面内的材料变多,使得柔性物料的硬度变大,从而实现坐垫硬度增加。反之,气袋放气过程中,水平挤压力减小,柔性物料单位截面内的材料减少,柔性物料的硬度降低,从而实现坐垫软度增加。
