Title (EN) POROUS BODY, ADDITIVE MANUFACTURING METHOD FOR THE BODY AND APPARATUS FOR SUPPORTING AND/OR BEARING A PERSON
(FR) CORPS POREUX, PROCÉDÉ DE FABRICATION ADDITIVE POUR LE CORPS, APPAREIL DE SUPPORT ET/OU DE PORTAGE DE PERSONNE
Abstract:
(EN) 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.
(FR) L'invention concerne un corps poreux (10, 20) qui comporte un réseau tridimensionnel de points nodaux (200) reliés les uns aux autres par des étrésillons (100) et un volume de vide (300) présent entre les étrésillons (100), ceux-ci (100) ayant une longueur moyenne de ≥ 200 µm à ≤ 50 mm, les étrésillons (100) ayant une épaisseur moyenne de ≥ 100 μm à ≤ 5 mm et le corps poreux ayant une dureté de compression (compression de 40 %, DIN EN ISO 3386-1 : 2010-09) dans au moins une direction spatiale de ≥ 10 à ≤ 100 kPa. Le corps poreux selon l'invention combine les avantages d'un matelas ou d'un coussin classique ayant une ventilation qui résulte de sa structure poreuse et qui ne peut pas être obtenue dans des mousses classiques. L'invention concerne en outre un procédé de fabrication d'un tel corps poreux (10, 20) et un appareil comprenant ledit corps (10, 20) pour supporter et/ou porter une personne.
