The invention discloses a double-layer soft structure polyurethane cushion, which comprises a cushion body, gauze is sewed on the inner wall of the cushion body, the cushion body is divided into a first filling chamber and a second filling chamber by the gauze, the inner wall of the first filling chamber is filled with polyurethane sponge, and a plurality of uniformly distributed hemispherical grooves are formed in the polyurethane sponge. Linen is fixed to the inner wall of the hemispherical groove and filled with down feather. By using the seat cushion body, the polyurethane sponge, the linen, the down feather and the gauze and utilizing the characteristics of the polyurethane sponge and the down feather, the elasticity of the seat cushion can be improved, and the seat cushion is more pressure-reducing, comfortable and breathable; the corrugated composite structure is formed by using the first composite fabric and the second composite fabric, so that the elasticity of the cushion is better, meanwhile, the polyurethane foam particles are filled in the corrugated composite structure, and the air bag is mounted in the corrugated composite structure, so that the elasticity of the cushion is further enhanced, and the impact force absorption and memory deformation capability of the cushion are improved.

    本发明公开了一种双层式软结构聚氨酯坐垫,包括坐垫本体,所述坐垫本体内壁缝制有纱布,且纱布将坐垫本体分隔为第一填充室和第二填充室,所述第一填充室内壁填充有聚氨酯海绵,且聚氨酯海绵上开有若干个均匀分布的半球槽,所述半球槽内壁固定有亚麻布,且亚麻布内填充有羽绒。本发明通过使用坐垫本体、聚氨酯海绵、亚麻布、羽绒和纱布,利用聚氨酯海绵和羽绒的特性,能够提高坐垫的弹性,且使得坐垫更加减压、舒适和透气;通过使用第一复合面料和第二复合面料,形成瓦楞复合结构,使得坐垫弹性更好,同时在瓦楞复合结构内填充聚氨酯泡沫粒和安装气囊,使得坐垫弹性得到进一步加强,提高了坐垫的吸收冲击力和记忆变形能力。
