| 发明名称 | Extrusion preventing supporting device | ||
| 摘要 | The invention relates to an extrusion preventing supporting device (30) comprising interconnected chain elements (40; 50, 55). Outwardly curved ends (42; 57, 58) of the chain elements (40; 50, 55) are adapted to be received by inwardly curved ends (43; 52, 53) of adjacent chain elements (40; 50, 55). Each chain element comprises a through connection bore (44; 54, 59). The extrusion preventing supporting device (30) further comprises one continuous connection wire 70 provided through the respective connection bores (44; 54, 59). | ||
