    • It is a feature of a porous body (10, 20) comprising a three-dimensional network of node points (200) joined to one another by struts (100), and a void volume (300) present between the struts (100), that the struts (100) have an average length of ≥ 200 μm to ≤ 50 mm, the struts (100) have an average thickness of ≥ 100 μm to ≤ 5 mm, and that the porous body has a compression hardness (40% compression, DIN EN ISO 3386-1 : 2010-09) in at least one spatial direction of ≥ 10 to ≤ 100 kPa. The porous body according to the invention combines the advantages of a conventional mattress or cushion with ventilatability which results from its porous structure and is not achievable in conventional foams. The invention further relates to a method of producing such a porous body (10, 20) and to an apparatus comprising said body (10, 20) for supporting and/or bearing a person.
    • 包括由支柱(100)彼此连接的节点(200)的三维网络以及空隙体积(300)的多孔体(10,20)的特征在于, 存在于所述支柱(100)之间,所述支柱(100)具有≥200μm至≤50mm的平均长度,所述支柱(100)具有≥100μm至≤5mm的平均厚度,并且所述多孔体 在≥10至≤100kPa的至少一个空间方向上具有压缩硬度(40%压缩,DIN EN ISO 3386-1:2010-09)。 根据本发明的多孔体将传统的床垫或衬垫的优点与由多孔结构产生的通风性结合起来,并且在传统泡沫中是不可实现的。 本发明进一步涉及一种制造这种多孔体(10,20)的方法以及包括用于支撑和/或承载人的所述主体(10,20)的设备。
