IPC分类号： F16B2/08
摘要： A support band (14) is described comprising a loop of a composite material, the loop including a curved region (20) that, in use, extends around part of a support (10), wherein the curved region (20) is of a curvature such that, at rest, voids are present between the band (14) and lateral parts of the support (10). When the support band (14) is used to support an object (12) from the support (10), the support band (14) needs bend to close the void before coming into contact with lateral parts of the support (10), whereby contact friction is avoided between the support band (14) and the support (10).
